Part III.) When, therefore, the mind is assailed by any emotion, the

body is at the same time affected with a modification whereby its power

of activity is increased or diminished. Now this modification of the body

(IV:v.) receives from its cause the force for persistence in its being;

which force can only be checked or destroyed by a bodily cause (II:vi.),

in virtue of the body being affected with a modification contrary to

(III:v.) and stronger than itself (IV.Ax.); wherefore (II:xii.) the mind

is affected by the idea of a modification contrary to, and stronger than

the former modification, in other words, (by the general definition

of the emotions) the mind will be affected by an emotion contrary to and

stronger than the former emotion, which will exclude or destroy the

existence of the former emotion; thus an emotion cannot be destroyed nor

controlled except by a contrary and stronger emotion. Q.E.D.

Corollary.- An emotion, in so far as it is referred to the mind, can

only be controlled or destroyed through an idea of a modification of

the body contrary to, and stronger than, that which we are undergoing.

For the emotion which we undergo can only be checked or destroyed by an

emotion contrary to, and stronger than, itself, in other words, (by the

general Definition of the Emotions) only by an idea of a modification

of the body contrary to, and stronger than, the modification which we

undergo.

Prop. VIII. The knowledge of good and evil

is nothing else but the emotions of pleasure

or pain, in so far as we are conscious

thereof.

Proof.- We call a thing good or evil, when it is of service or the

reverse in preserving our being (IV:Def.i.&.ii.), that is (III:vii.),

when it increases or diminishes, helps or hinders, our power of activity.

Thus, in so far as we perceive that a thing affects us with pleasure or

pain, we call it good or evil; wherefore the knowledge of good and evil

is nothing else but the idea of the pleasure or pain, which necessarily

follows from that pleasurable or painful emotion (II:xxii.). But this idea

is united to the emotion in the same way as mind is united to body

(II:xxi.); that is, there is no real distinction between this idea and

the emotion or idea of the modification of the body, save in conception

only. Therefore the knowledge of good and evil is nothing else but the

emotion, in so far as we are conscious thereof. Q.E.D.

Prop. IX. An emotion, whereof we conceive

the cause to be with us at the present time,

is stronger than if we did not conceive the

cause to be with us.

Proof.- Imagination or conception is the idea, by which the mind regards

a thing as present (II:xvii.note), but which indicates the disposition of

the mind rather than the nature of the external thing (II:xvi.Coroll.ii).

An emotion is therefore a conception, in so far as it indicates the

disposition of the body. But a conception (by II:xvii.) is stronger,

so long as we conceive nothing which excludes the present existence

of the external object; wherefore an emotion is also stronger or more

intense, when we conceive the cause to be with us at the present time,

than when we do not conceive the cause to be with us. Q.E.D.

Note.- When I said above in III:xviii. that we are affected by the image

of what is past or future with the same emotion as if the thing conceived

were present, I expressly stated, that this is only true in so far as we

look solely to the image of the thing in question itself ; for the thing's

nature is unchanged, whether we have conceived it or not; I did not deny

that the image becomes weaker, when we regard as present to us other

things which exclude the present existence of the future object: I did

not expressly call attention to the fact, because I purposed to treat

of the strength of the emotions in this part of my work.

Corollary.- The image of something past or future, that is, of a thing

which we regard as in relation to time past or time future, to the

exclusion of time present, is, when other conditions are equal, weaker

than the image of something present; consequently an emotion felt towards

what is past or future is less intense, other conditions being equal,

than an emotion felt towards something present.

Prop. X. Towards something future, which we

conceive as close at hand, we are affected

more intensely, than if we conceive that

its time for existence is separated from

the present by a longer interval; so too

by the remembrance of what we conceive to

have not long passed away we are affected

more intensely, than if we conceive that

it has long passed away.

Proof.- In so far as we conceive a thing as close at hand, or not long

passed away, we conceive that which excludes the presence of the object

less, than if its period of future existence were more distant from the

present, or if it had long passed away (this is obvious) therefore (by the

foregoing Prop.) we are, so far, more intensely affected towards it. Q.E.D.

Corollary.- From the remarks made in IV:Def.vi. of this part it follows

that, if objects are separated from the present by a longer period than

we can define in conception, though their dates of occurrence be widely

separated one from the other, they all affect us equally faintly.

Prop. XI. An emotion towards that which

we conceive as necessary is, when other

conditions are equal, more intense than

an emotion towards that which impossible,

or contingent, or non-necessary.

Proof.- In so far as we conceive a thing to be necessary, we, to that

extent, affirm its existence; on the other hand we deny a thing's

existence, in so far as we conceive it not to be necessary :xxxiii.note.i.);

wherefore (IV.ix.) an emotion towards that which is necessary is, other

conditions being equal, more intense than an emotion that which is

non-necessary. Q.E.D.

Prop. XII. An emotion towards a thing,

which we know not to exist at the present

time, and which we conceive as possible,

is more intense, other conditions being

equal, than an emotion towards a thing

contingent.

Proof.- In so far as we conceive a thing as contingent, we are affected

by the conception of some further thing, which would assert the existence

of the former (IV:Def.iii.); but, on the other hand, we (by hypothesis)

conceive certain things, which exclude its present existence. But, in

so far as we conceive a thing to be possible in the future, we there by

conceive things which assert its existence (IV:iv.), that is (III:xviii.),

things which promote hope or fear: wherefore an emotion towards something

possible is more vehement. Q.E.D.

Corollary.- An emotion towards a thing, which we know not to exist in the

present, and which we conceive as contingent, is far fainter, than if we

conceive the thing to be present with us.

Proof.- Emotion towards a thing, which we conceive to exist, is more

intense than it would be, if we conceived the thing as future V:ix.Coroll.),

and is much more vehement, than if the future time be conceived as far

distant from the present (IV:x.). Therefore an emotion towards a thing,

whose period of existence we conceive to be far distant from the present,

is far fainter, than if we conceive the thing as present; it is,

nevertheless, more intense, than if we conceived the thing as contingent,

wherefore an emotion towards a thing, which we regard as contingent,

will be far fainter, than if we conceived the thing to be present with us.

Q.E.D.

Prop. XIII. Emotion towards a thing contingent,

which we know not to exist in the present, is,

other conditions being equal, fainter than an

emotion towards a thing past.

Proof.- In so far as we conceive a thing as contingent, we are not

affected by the image of any other thing, which asserts the existence

of the said thing (IV:Def.iii.), but, on the other hand (by hypothesis),

we conceive certain things excluding its present existence. But, in so

far as we conceive it in relation to time past, we are assumed to

conceive something, which recalls the thing to memory, or excites the

image thereof (II:xviii.&Note), which is so far the same as regarding

it as present (II:xvii.Coroll.). Therefore (IV:ix.) an emotion towards a

thing contingent, which we know does not exist in the present, is fainter,

other conditions being equal, than an emotion towards a thing past. Q.E.D.

Prop. XIV. A true knowledge of good and evil

cannot check any emotion by virtue of being true,

but only in so far as it is considered as an emotion.

Proof.- An emotion is an idea, whereby the mind affirms of its body a

greater or less force of existing than before (by the general Definition

of the Emotions); therefore it has no positive quality, which can be

destroyed by the presence of what is true; consequently the knowledge

of good and evil cannot, by virtue oi being true, restrain any emotion.

But, in so far as such knowledge is an emotion (IV:viii.) if it have

more strength for restraining emotion, it will to that extent be able

to restrain the given emotion. Q.E.D.

Prop. XV. Desire arising from the

knowledge of good and bad can be

quenched or checked by many of the

other desires arising from the

emotions whereby we are assailed.

Proof.- From the true knowledge of good and evil, in so far as it is an

emotion, necessarily arises desire (Def. of the Emotions, i.), the strength

of which is proportioned to the strength of the emotion wherefrom it arises

(III:xxxvii.). But, inasmuch as this desire arises (by hypothesis) from the

fact of our truly understanding anything, it follows that it is also

present with us, in so far as we are active (III:i.), and must therefore

be understood through our essence only (III:Def.ii.); consequently

(III:vii.) its force and increase can be defined solely by human power.

Again, the desires arising from the emotions whereby we are assailed are

stronger, in proportion as the said emotions are more vehement; wherefore

their force and increase must be defined solely by the power of external

causes, which, when compared with our own power, indefinitely surpass it

(IV:iii.); hence the desires arising from like emotions may be more

vehement, than the desire which arises from a true knowledge of good and

evil, and may, consequently, control or quench it. Q.E.D.

Prop. XVI. Desire arising from the knowledge

of good and evil, in so far as such knowledge

regards what is future, may be more easily

controlled or quenched, than the desire for

what is agreeable at the present moment.

Proof.- Emotion towards a thing, which we conceive as future, is fainter

than emotion towards a thing that is present (IV:ix.Coroll.). But desire,

which arises from the true knowledge of good and evil, though it be

concerned with things which are good at the moment, can be quenched

or controlled by any headstrong desire (by the last Prop., the proof

whereof is of universal application). Wherefore desire arising from

such knowledge, when concerned with the future, can be more easily

controlled or quenched, &c. Q.E.D.

Prop. XVII. Desire arising from the true

knowledge of good and evil, in so far as

such knowledge is concerned with what is

contingent, can be controlled far more

easily still, than desire for things

that are present.

Proof.- This Prop. is proved in the same way as the last Prop. from

IV:xii.Coroll.

Note.- I think I have now shown the reason, why men are moved by opinion

more readily than by true reason, why it is that the true knowledge of good

and evil stirs up conflicts in the soul, and often yields to every kind of

passion. This state of things gave rise to the exclamation of the poet:

(Ov. Met. vii.20, "Video meliora proboque, Deteriora sequor.")

The better path I gaze at and approve,

The worse - I follow."

Ecclesiastes seems to have had the same thought in his mind, when he says,

"He who increaseth knowledge increaseth sorrow." I have not written the

above with the object of drawing the conclusion, that ignorance is more

excellent than knowledge, or that a wise man is on a par with a fool in

controlling his emotions, but because it is necessary to know the power

and the infirmity of our nature, before we can determine what reason can

do in restraining the emotions, and what is beyond her power. I have said,

that in the present part I shall merely treat of human infirmity. The

power of reason over the emotions I have settled to treat separately.

Prop. XVIII. Desire arising from pleasure is,

other conditions being equal, stronger than

desire arising from pain.

Proof.- Desire is the essence of a man (Def. of the Emotions, i.),

that is, the endeavour whereby a man endeavours to persist in his own

being. Wherefore desire arising from pleasure is, by the fact of

pleasure being felt, increased or helped; on the contrary, desire

arising from pain is, by the fact of pain being felt, diminished or

hindered; hence the force of desire arising from pleasure must be

defined by human power together with the power of an external cause,

whereas desire arising from pain must be defined by human power only.

Thus the former is the stronger of the two. Q.E.D.

Note.- In these few remarks I have explained the causes of human infirmity

and inconstancy, and shown why men do not abide by the precepts of reason.

It now remains for me to show what course is marked out for us by reason,

which of the emotions are in harmony with the rules of human reason, and

which of them are contrary thereto.

But, before I begin to prove my Propositions in detailed geometrical

fashion, it is advisable to sketch them briefly in advance, so that

everyone may more readily grasp my meaning.

As reason makes no demands contrary to nature, it demands, that every

man should love himself, should seek that which is useful to him - I mean,

that which is really useful to him, should desire everything which really

brings man to greater perfection, and should, each for himself, endeavour

as far as he can to preserve his own being. This is as necessarily true,

as that a whole is greater than its part. (Cf. III:iv.)

Again, as virtue is nothing else but action in accordance with the

laws of one's own nature (IV:Def.viii.), and as no one endeavours to

preserve his own being, except in accordance with the laws of his own

nature, it follows, first, that the foundation of virtue is the endeavour

to preserve one's own being, and that happiness consists in man's power

of preserving, his own being; secondly, that virtue is to be desired for

its own sake, and that there is nothing more excellent or more useful to

us, for the sake of which we should desire it; thirdly and lastly that

suicides are weak-minded, and are overcome by external causes repugnant to

their nature. Further, it follows from Postulate iv. Part.II., that we can

never arrive at doing without all external things for the preservation of

our being or living, so as to have no relations with things

which are outside ourselves. Again, if we consider our mind, we see that

our intellect would be more imperfect, if mind were alone, and could

understand nothing besides itself. There are, then, many things outside

ourselves, which are useful to us, and are, therefore, to be desired.

Of such none can be discerned more excellent, than those which are in

entire agreement with our nature. For if, for example, two individuals

of entirely the same nature are united, they form a combination twice

as powerful as either of them singly.

Therefore, to man there is nothing more useful than man - nothing,

I repeat, more excellent for preserving their being can be wished for

by men, than that all should so in all points agree, that the minds and

bodies of all should form, as it were, one single mind and one single

body, and that all should, with one consent, as far as they are able,

endeavour to preserve their being, and all with one consent seek what is

useful to them all. Hence, men who are governed by reason - that is, who

seek what is useful to them in accordance with reason, desire for

themselves nothing, which they do not also desire for the rest of mankind,

and, consequently, are just, faithful, and honourable in their conduct.

Such are the dictates of reason, which I purposed thus briefly to

indicate, before beginning to prove them in greater detail. I have taken

this course, in order, if possible, to gain the attention of those who

believe, that the principle that every man is bound to seek what is useful

for himself is the foundation of impiety, rather than of piety and virtue.

Therefore, after briefly showing that the contrary is the case, I go

on to prove it by, the same method, as that whereby I have hitherto

proceeded.

Prop. XIX. Every man, by the laws of his

nature, necessarily desires or shrinks

from that which he deems to be good or bad.

Proof.- The knowledge of good and evil is (IV:viii.) the emotion of

pleasure or pain, in so far as we are conscious thereof; therefore,

every man necessarily desires what he thinks good, and shrinks from

what he thinks bad. Now this appetite is nothing else but man's nature

or essence (Cf. the Definition of Appetite, III.ix.note, and Def. of

the Emotions, i.). Therefore, every man, solely by the laws of his

nature, desires the one, and shrinks from the other, &c. Q.E.D.

Prop. XX. The more every man endeavours,

and is able to seek what is useful to him -

in other words, to preserve his own being -

the more is he endowed with virtue; on the

contrary, in proportion as a man neglects

to seek what is useful to him, that is, to

preserve his own being, he is wanting in power.

Proof.- Virtue is human power, which is defined solely by man's essence

(IV:Def.viii.), that is, which is defined solely by the endeavour made by

man to persist in his own being. Wherefore, the more a man endeavours,

and is able to preserve his own being, the more is he endowed with virtue,

and, consequently (III:iv.&,vi.), in so far as a man neglects to

preserve his own being, he is wanting in power. Q.E.D.

Note.- No one, therefore, neglects seeking his own good, or preserving his

own being, unless he be overcome by causes external and foreign to his

nature. No one, I say, from the necessity of his own nature, or otherwise

than under compulsion from external causes, shrinks from food, or kills

himself: which latter may be done in a variety of ways. A man, for

instance, kills himself under the compulsion of another man, who twists

round his right hand, wherewith he happened to have taken up a sword, and

forces him to turn the blade against his own heart; or, again, he may be

compelled, like Seneca, by a tyrant's command, to open his own veins -

that is, to escape a greater evil by incurring, a lesser; or, lastly,

latent external causes may so disorder his imagination, and so affect his

body, that it may assume a nature contrary to its former one, and whereof

the idea cannot exist in the mind (III:x.) But that a man, from the

necessity of his own nature, should endeavour to become non-existent, is

as impossible as that something should be made out of nothing, as everyone

will see for himself, after a little reflection.

Prop. XXI. No one can desire to be blessed,

to act rightly, and to live rightly, without

at the same time wishing to be, act, and to

live - in other words, to actually exist.

Proof.- The proof of this proposition, or rather the proposition itself,

is self-evident, and is also plain from the definition of desire. For the

desire of living, acting, &C., blessedly or rightly, is (Def. of the

Emotions, i.) the essence of man - that is (III:vii.), the endeavour

made by everyone to preserve his own being. Therefore, no one can

desire, &c. Q.E.D.

Prop. XXII. No virtue can be conceived

as prior to this endeavour to preserve

one's own being.

Proof.- The effort for self-preservation is the essence of a thing

(III:vii.); therefore, if any virtue could be conceived as prior

thereto, the essence of a thing would have to be conceived as

prior to itself, which is obviously absurd. Therefore no virtue, &c.

Q.E.D.

Corollary.- The effort for self-preservation is the first and only

foundation of virtue. For prior to this principle nothing can be

conceived, and without it no virtue can be conceived.

Prop. XXIII. Man, in so far as he is

determined to a particular action

because he has inadequate ideas,

cannot be absolutely said to act in

obedience to virtue; he can only be

so described, in so far as he is

determined for the action because

he understands.

Proof.- In so far as a man is determined to an action through having

inadequate ideas, he is passive (III:i.), that is (III:Def.i., &iii.),

he does something, which cannot be perceived solely through his essence,

that is (by IV:Def.viii.), which does not follow from his virtue. But,

in so far as he is determined for an action because he understands, he

is active; that is, he does something, which is perceived through his

essence alone, or which adequately follows from his virtue. Q.E.D.

Prop. XXIV. To act absolutely in obedience

to virtue is in us the same thing as to act,

to live, or to preserve one's being (these

three terms are identical in meaning) in

accordance with the dictates of reason on the

basis of seeking what is useful to one's self.

Proof.- To act absolutely in obedience to virtue is nothing else but

to act according to the laws of one's own nature. But we only act, in

so far as we understand (III:iii.) : therefore to act in obedience to

virtue is in us nothing else but to act, to live, or to preserve one's

being in obedience to reason, and that on the basis of seeking what is

useful for us (IV:xxii.Coroll.). Q.E.D.

Prop. XXV. No one wishes to preserve his

being for the sake of anything else.

Proof.- The endeavour, wherewith everything endeavours to persist in its

being, is defined solely by the essence of the thing itself (III:vii.);

from this alone, and not from the essence of anything else, it necessarily

follows (III:vi.) that everyone endeavours to preserve his being.

Moreover, this proposition is plain from IV:xxii.Coroll., for if a man

should endeavour to preserve his being for the sake of anything else, the

last-named thing would obviously be the basis of virtue, which, by the

foregoing corollary, is absurd. Therefore no one, &c. Q.E.D.

Prop. XXVI. Whatsoever we endeavour in

obedience to reason is nothing further

than to understand; neither does the mind,

in so far as it makes use of reason, judge

anything to be useful to it, save such

things as are conducive to understanding.

Proof.- The effort for self-preservation is nothing else but the essence

of the thing in question (III:vii.), which, in so far as it exists such

as it is, is conceived to have force for continuing in existence (III:vi.)

and doing such things as necessarily follow from its given nature (see the

Def. of Appetite, II:ix.Note). But the essence of reason is nought else but

our mind, in so far as it clearly and distinctly understands (see the

definition in II:xl.Note:ii.) ; therefore (III:xl.) whatsoever we endeavour

in obedience to reason is nothing else but to understand. Again, since this

effort of the mind wherewith the mind endeavours, in so far as it reasons,

to preserve its own being is nothing else but understanding; this effort

at understanding is (IV:xxii.Coroll.) the first and single basis of virtue,

nor shall we endeavour to understand things for the sake of any ulterior

object (IV:xxv.); on the other hand, the mind, in so far as it reasons,

will not be able to conceive any good for itself, save such things as are

conducive to understanding.

Prop. XXVII. We know nothing to be certainly

good or evil, save such things as really

conduce to understanding, or such as are

able to hinder us from understanding.

Proof.- The mind, in so far as it reasons, desires nothing beyond

understanding, and judges nothing to be useful to itself, save such

things as conduce to understanding (by the foregoing Prop.). But the

mind (II:xli.&Note) cannot possess certainty concerning anything,

except in so far as it has adequate ideas, or (what by II:xl.Note,

is the same thing) in so far as it reasons. Therefore we know nothing

to be good or evil save such things as really conduce, &c. Q.E.D.

Prop. XXVIII. The mind's highest good is

the knowledge of God, and the mind's

highest virtue is to know God.

Proof.- The mind is not capable of understanding anything higher than God,

that is (I:Def.vi.), than a Being absolutely infinite, and without which

(I:xv.) nothing can either be or be conceived; therefore (IV:xxvi.,

&xxvii.), the mind's highest utility or (IV:Def.i.) good is the knowledge

of God. Again, the mind is active, only in so far as it understands, and

only to the same extent can it be said absolutely to act virtuously. The

mind's absolute virtue is therefore to understand. Now, as we have already

shown, the highest that the mind can understand is God; therefore the

highest virtue of the mind is to understand or to know God. Q.E.D.

Prop. XXIX. No individual thing, which is

entirely different from our own nature,

can help or check our power of activity, and

absolutely nothing can do us good or harm,

unless it has something in common with our nature.

Proof.- The power of every individual thing, and consequently the power of

man, whereby he exists and operates, can only be determined by an

individual thing (I:xxviii.), whose nature (II:vi.) must be understood

through the same nature as that, through which human nature is conceived.

Therefore our power of activity, however it be conceived, can be determined

and consequently helped or hindered by the power of any other individual

thing, which has something in common with us, but not by the power of

anything, of which the nature is entirely different from our own; and

since we call good or evil that which is the cause of pleasure or pain

(IV:viii.), that is (III:xi.Note), which increases or diminishes, helps

or hinders, our power of activity; therefore, that which is entirely,

different from our nature can neither be to us good nor bad. Q.E.D.

Prop. XXX. A thing cannot be bad for us

through the quality which it has in common

with our nature, but it is bad for us in so

far as it is contrary to our nature.

Proof.- We call a thing bad when it is the cause of pain (IV:viii.), that

is (by the Def., which see in III:xi.Note), when it diminishes or checks

our power of action. Therefore, if anything were bad for us through that

quality which it has in common with our nature, it would be able

itself to diminish or check that which it has in common with our nature,

which (III:iv.) is absurd. Wherefore nothing can be bad for us through

that quality which it has in common with us, but, on the other hand, in

so far as it is bad for us, that is (as we have just shown), in so far as

it can diminish or check our power of action, it is contrary to our nature.

Q.E.D.

Prop. XXXI. In so far as a thing is in harmony

with our nature, it is necessarily good.

Proof.- In so far as a thing is in harmony with our nature, it cannot be

bad for it. It will therefore necessarily be either good or indifferent.

If it be assumed that it be neither good nor bad, nothing will follow from

its nature (IV:Def.i.), which tends to the preservation of our nature,

that is (by the hypothesis), which tends to the preservation of the thing

itself; but this (III:vi.) is absurd; therefore, in so far as a thing is

in harmony with our nature, it is necessarily good. Q.E.D.

Corollary.- Hence it follows, that, in proportion as a thing is in harmony

with our nature, so is it more useful or better for us, and vice versa, in

proportion as a thing is more useful for us, so is it more in harmony with

our nature. For, in so far as it is not in harmony with our nature, it

will necessarily be different therefrom or contrary thereto. If different,

it can neither be good nor bad (IV:xxix.); if contrary, it will be contrary

to that which is in harmony with our nature, that is, contrary to what is

good - in short, bad. Nothing, therefore, can be good, except in so far as

it is in harmony with our nature; and hence a thing is useful, in proportion

as it is in harmony with our nature, and vice versa. Q.E.D.

Prop. XXXII. In so far as men are a prey

to passion, they cannot, in that respect,

be said to be naturally in harmony.

Proof. Things, which are said to be in harmony naturally, are understood to

agree in power (III:vii.), not in want of power or negation, and

consequently not in passion (III:iii.Note); wherefore men, in so far as

they are a prey to their passions, cannot be said to be naturally in

harmony. Q.E.D.

Note.- This is also self-evident; for, if we say that white and black only

agree in the fact that neither is red, we absolutely affirm that the do not

agree in any respect. So, if we say that a man and a stone only agree in the

fact that both are finite - wanting in power, not existing by the necessity

of their own nature, or, lastly, indefinitely surpassed by the power of

external causes - we should certainly affirm that a man and a stone are in

no respect alike; therefore, things which agree only in negation, or in

qualities which neither possess, really agree in no respect.

Prop. XXXIII. Men can differ in nature,

in so far as they are assailed by those

emotions, which are passions, or passive

states; and to this extent one and the

same man is variable and inconstant.

Proof.- The nature or essence of the emotions cannot be explained solely

through our essence or nature (III:Def.i.&ii.), but it must be defined by

the power, that is (III:vii.), by the nature of external causes in

comparison with our own; hence it follows, that there are as many kinds of

each emotion as there are external objects whereby we are affected

(III:lvi.), and that men may be differently affected by one and the same

object (III:li), and to this extent differ in nature; lastly, that one and

the same man may be differently affected towards the same object, and may

therefore be variable and inconstant. Q.E.D.

Prop. XXXIV. In so far as men are assailed

by emotions which are passions, they can be

contrary one to another.

Proof.- A man, for instance Peter, can be the cause of Paul's feeling pain,

because he (Peter) possesses something similar to that which Paul hates

(III:xvi.), or because Peter has sole possession of a thing which Paul also

loves (III:xxxii.&Note), or for other causes (of which the chief are

enumerated in III:lv.Note) ; it may therefore happen that Paul should hate

Peter (Def. of Emotions: vii.), consequently it may easily happen also, that

Peter should hate Paul in return, and that each should endeavour to do the

other an injury, (III:xxxix.), that is (IV:xxx.), that they should be

contrary one to another. But the emotion of pain is always a passion

or passive state (III:lix.); hence men, in so far as they are assailed by

emotions which are passions, can be contrary one to another. Q.E.D.

Note.- I said that Paul may hate Peter, because he conceives that Peter

possesses something which he (Paul) also loves; from this it seems, at first

sight, to follow, that these two men, through both loving the same thing,

and, consequently, through agreement of their respective natures, stand in

one another's way; if this were so, II:xxx. and II:xxxi. would be untrue.

But if we give the matter our unbiased attention, we shall see that the

discrepancy vanishes. For the two men are not in one another's way in

virtue of the agreement of their natures, that is, through both loving the

same thing, but in virtue of one differing from the other. For, in so far

as each loves the same thing, the love of each is fostered thereby

(III:xxxi.), that is (Def. of the Emotions: vi.) the pleasure of each is

fostered thereby. Wherefore it is far from being the case, that they are

at variance through both loving the same thing, and through the agreement

in their natures. The cause for their opposition lies, as I have said,

solely in the fact that they are assumed to differ. For we assume that

Peter has the idea of the loved object as already in his possession, while

Paul has the idea of the loved object as lost. Hence the one man will be

affected with pleasure, the other will be affected with pain, and thus they

will be at variance one with another. We can easily show in like manner,

that all other causes of hatred depend solely on differences, and not on

the agreement between men's natures.

Prop. XXXV. In so far only as men live

in obedience to reason, do they always

necessarily agree in nature.

Proof.- In so far as men are assailed by emotions that are passions, they

can be different in nature (IV:xxxiii.), and at variance one with another.

But men are only said to be active, in so far as they act in obedience to

reason (III:iii.); therefore, what so ever follows from human nature in so

far as it is defined by reason must (III:Def.ii.) be understood solely

through human nature as its proximate cause. But, since every man by the

laws of his nature desires that which he deems good, and endeavours to

remove that which he deems bad (IV:xix.); and further, since that which we,

in accordance with reason, deem good or bad, necessarily is good

or bad (II:xli.); it follows that men, in so far as they live in obedience

to reason, necessarily do only such things as are necessarily good for

human nature, and consequently for each individual man (IV:xxxi.Coroll.);

in other words, such things as are in harmony with each man's nature.

Therefore, men in so far as they live in obedience to reason, necessarily

live always in harmony one with another. Q.E.D.

Corollary I - There is no individual thing in nature, which is

more useful to man, than a man who lives in obedience to reason. For that

thing is to man most useful, which is most in harmony with his nature

(IV:xxxi.Coroll.); that is, obviously, man. But man acts absolutely

according to the laws of his nature, when he lives in obedience to reason

(III:Def.ii.), and to this extent only is always necessarily in harmony

with the nature of another man (by the last Prop.); wherefore among

individual things nothing is more useful to man, than a man who lives in

obedience to reason. Q.E.D.

Corollary II.- As every man seeks most that which is useful to him, so are

men most useful one to another. For the more a man seeks what is useful to

him and endeavours to preserve himself, the more is he endowed with virtue

(IV:xx.), or, what is the same thing (IV:Def.viii.), the more is he endowed

with power to act according to the laws of his own nature, that is to live

in obedience to reason. But men are most in natural harmony, when they live

in obedience to reason (by the last Prop.); therefore (by the foregoing

Coroll.) men will be most useful one to another, when each seeks most that

which is useful to him. Q.E.D.

Note.- What we have just shown is attested by experience so conspicuously,

that it is in the mouth of nearly everyone: "Man is to man a God." Yet it

rarely happens that men live in obedience to reason, for things are so

ordered among them, that they are generally envious and troublesome one to

another. Nevertheless they are scarcely able to lead a solitary life,

so that the definition of man as a social animal has met with general

assent; in fact, men do derive from social life much more convenience than

injury. Let satirists then laugh their fill at human affairs, let

theologians rail, and let misanthropes praise to their utmost the life of

untutored rusticity, let them heap contempt on men and praises on beasts;

when all is said, they will find that men can provide for their wants much

more easily by mutual help, and that only by uniting their forces can they

escape from the dangers that on every side beset them: not to say how much

more excellent and worthy of our knowledge it is, to study the actions of

men than the actions of beasts. But I will treat of this more at

length elsewhere.

Prop. XXXVI. The highest good of those

who follow virtue is common to all,

and therefore all can equally rejoice

therein.

Proof.- To act virtuously is to act in obedience with reason (IV:xxiv.),

and whatsoever we endeavour to do in obedience to reason is to understand

(IV:xxvi.); therefore (IV:xxviii.) the highest good for those who follow

after virtue is to know God; that is (II:xlvii.&Note) a good which is

common to all and can be possessed. by all men equally, in so far as they

are of the same nature. Q.E.D.

Note.- Someone may ask how it would be, if the highest good of those who

follow after virtue were not common to all? Would it not then follow, as

above (IV:xxxiv.), that men living in obedience to reason, that is

(IV:xxxv.), men in so far as they agree in nature, would be at variance

one with another? To such an inquiry, I make answer, that it follows not

accidentally but from the very nature of reason, that main's highest good

is common to all, inasmuch as it is deduced from the very essence of man,

in so far as defined by reason; and that a man could neither be, nor be

conceived without the power of taking pleasure in this highest good. For

it belongs to the essence of the human mind (II:xlvii.), to have an

adequate knowledge of the eternal and infinite essence of God.

Prop. XXXVII. The good which every man,

who follows after virtue, desires for

himself he will also desire for other

men, and so much the more, in proportion

as he has a greater knowledge of God.

Proof.- Men, in so far as they live in obedience to reason, are most

useful to their fellow men (IV:xxxv;Coroll.i.); therefore (IV:xix.),

we shall in obedience to reason necessarily endeavour to bring about that

men should live in obedience to reason. But the good which every man, in

so far as he is guided by reason, or, in other words, follows after virtue,

desires for himself, is to understand (IV:xxvi.); wherefore the good, which

each follower of virtue seeks for himself, he will desire also for others.

Again, desire, in so far as it is referred to the mind, is the very

essence of the mind (Def. of the Emotions, i.); now the essence of the

mind consists in knowledge (III:xi.), which involves the knowledge of God

(II:xlvii.), and without it (I:xv.), can neither be, nor be conceived;

therefore, in proportion as the mind's essence involves a greater knowledge

of God, so also will be greater the desire of the follower of virtue, that

other men should possess that which he seeks as good for himself. Q.E.D.

Another Proof.- The good, which a man desires for himself and loves, he

will love more constantly, if he sees that others love it also (III:xxxi.);

he will therefore endeavour that others should love it also; and as the

good in question is common to all, and therefore all can rejoice therein,

he will endeavour, for the same reason, to bring about that all should

rejoice therein, and this he will do the more (III:xxxvii.), in proportion

as his own enjoyment of the good is greater.

Note 1- He who, guided by emotion only, endeavours to cause others to love

what he loves himself, and to make the rest of the world live according to

his own fancy, acts solely by impulse, and is, therefore, hateful,

especially, to those who take delight in something different, and

accordingly study and, by similar impulse, endeavour, to make men live in

accordance with what pleases themselves. Again, as the highest good sought

by men under the guidance of emotion is often such, that it can only be

possessed by a single individual, it follows that those who love it are not

consistent in their intentions, but, while they delight to sing its praises,

fear to be believed. But he, who endeavours to lead men by reason, does not

act by impulse but courteously and kindly, and his intention is always

consistent. Again, whatsoever we desire and do, whereof we are the cause

in so far as we possess the idea of God, or know God, I set down to

Religion. The desire of well-doing, which is engendered by a life

according to reason, I call piety. Further, the desire, whereby a

man living according to reason is bound to associate others with

himself in friendship, I call honour (Honestas); by honourable I mean

that which is praised by men living according to reason, and by base

I mean that which is repugnant to the gaining of friendship. I have also

shown in addition what are the foundations of a state; and the difference

between true ,virtue and infirmity may be readily gathered from what I

have said; namely, that true virtue is nothing else but living in

accordance with reason; while infirmity is nothing else but man's

allowing himself to be led by things which are external to himself,

and to be by them determined to act in a manner demanded by the general

disposition of things rather than by his own nature considered solely

in itself.

Such are the matters which I engaged to prove in IV:xviii., whereby it

is plain that the law against the slaughtering of animals is founded rather

on vain superstition and womanish pity than on sound reason. The rational

quest of what is useful to us further teaches us the necessity of

associating ourselves with our fellow men, but - not with beasts, or things,

whose nature is different from our own; we have the same rights in respect

to them as they have in respect to us. Nay, as everyone's right is defined

by his virtue, or power, men have far greater rights over beasts than

beasts have over men. Still I do not deny that beasts feel: what I deny is,

that we may not consult our own advantage and use them as we please,

treating them in the way which best suits us; for their nature is not like

ours, and their emotions are naturally different from human emotions

(III:Ivii.Note). It remains for me to explain what I mean by, just and

unjust, sin and merit. On these points see the following note.

Note II.- In the Appendix to Part I. I undertook to explain praise and

blame, merit and sin, justice and injustice.

Concerning praise and blame I have spoken in III:xxix.Note: the time

has now come to treat of the remaining terms. But I must first say a few

words concerning man in the state of nature and in society.

Every man exists by sovereign natural right, and, consequently, by

sovereign natural right performs those actions which follow from the

necessity of his own nature; therefore by sovereign natural right every man

judges what is good and what is bad, takes care of his own advantage

according to his own disposition (IV:xix. and IV:xx.), avenges the wrongs

done to him (III:xl.Coroll. ii.), and endeavours to preserve that which he

loves and to destroy - that which he hates (III:xxviii.). Now, if men lived

under the guidance of reason, everyone would remain in possession of this

his right, without any injury being done to his neighbour V:xxxv.Coroll.i.).

But seeing that they are a prey to their emotions, which far surpass human

power or virtue (IV:vi.), they are often drawn in different directions, and

being at variance one with another (IV:xxxiii., xxxiv.), stand in need of

mutual help (IV:xxxv.Note). Wherefore, in order that men may live together

in harmony, and may aid one another, it is necessary that they should

forego their natural right, and, for the sake of security, refrain from

all actions which can injure their fellow-men. The way in which this end

can be obtained, so that men who are necessarily a prey to their emotions

(IV:iv.Coroll.), inconstant, and diverse, should be able to render each

other mutually secure, and feel mutual trust, is evident from IV:vii. and

III:xxxix. It is there shown, that an emotion can only be restrained by an

emotion stronger than, and contrary to itself, and that men avoid inflicting

injury through fear of incurring a greater injury themselves.

On this law society can be established, so long as it keeps in its own

hand the right, possessed by everyone, of avenging injury, and pronouncing

on good and evil; and provided it also possesses the power to lay down a

general rule of conduct, and to pass laws sanctioned, not by reason, which

is powerless in restraining emotion, but by threats (IV:xvii.Note). Such a

society established with laws and the power of preserving itself is called

a State, while those who live under its protection are called citizens. We

may readily understand that there is in the state of nature nothing, which

by universal consent is pronounced good or bad; for in the state of nature

everyone thinks solely of his own advantage, and according to his

disposition, with reference only to his individual advantage, decides

what is good or bad, being bound by no law to anyone besides himself.

In the state of nature, therefore, sin is inconceivable; it can only

exist in a state, where good and evil are pronounced on by common consent,

and where everyone is bound to obey the State authority. Sin, then,

is nothing else but disobedience, which is therefore punished by the right

of the State only. Obedience, on the other hand, is set down as merit,

inasmuch as a man is thought worthy of merit, if he takes delight in the

advantages which a State provides.

Again, in the state of nature, no one is by common consent master of

anything, nor is there anything in nature, which can be said to belong to

one man rather than another: all things are common to all. Hence, in the

state of nature, we can conceive no wish to render to every man his own,

or to deprive a man of that which belongs to him; in other words, there is

nothing in the state of nature answering to justice and injustice. Such

ideas are only possible in a social state, when it is decreed by common

consent what belongs to one man and what to another.

From all these considerations it is evident, that justice and

injustice, sin and merit, are extrinsic ideas, and not attributes which

display the nature of the mind. But I have said enough.

Prop. XXXVIII. Whatsoever disposes the human

body, so as to render it capable of being

affected in an increased number of ways, or

of affecting external bodies in an increased

number of ways, is useful to man ; and is so,

in proportion as the body is thereby rendered

more capable of being affected or affecting

other bodies in an increased number of ways;

contrariwise, whatsoever renders the body less

capable in this respect is hurtful to man.

Proof.- Whatsoever thus increases the capabilities of the body increases

also the mind's capability of perception (II:xiv.); therefore, whatsoever

thus disposes the body and thus renders it capable, is necessarily good or

useful (IV:xxvi., IV:xxvii.); and is so in proportion to the extent to

which it can render the body capable; contrariwise (II:xiv., IV:xxvi.,

IV:xxvii.), it is hurtful, if it renders the body in this respect less

capable. Q.E.D.

Prop. XXXIX. Whatsoever brings about

the preservation of the proportion of

motion and rest, which the parts of

the human body mutually possess, is

good; contrariwise, whatsoever causes

a change in such proportion is bad.

Proof.- The human body needs many other bodies for its preservation

(II:Post.iv.). But that which constitutes the specific reality (forma)

of a human body is, that its parts communicate their several motions

one to another in a certain fixed proportion (Def. before Lemma iv. after

II:xiii.). Therefore, whatsoever brings about the preservation of the

proportion between motion and rest, which the parts of the human body

mutually possess, preserves the specific reality of the human body, and

consequently renders the human body capable of being affected in many ways

and of affecting external bodies in many ways; consequently it is good

(by the last Prop.). Again, whatsoever brings about a change in the

aforesaid proportion causes the human body to assume another specific

character, in other words (see Preface to this Part towards the end,

though the point is indeed self-evident), to be destroyed, and

consequently totally incapable of being affected in an increased

numbers of ways; therefore it is bad. Q.E.D.

Note.- The extent to which such causes can injure or be of service to the

mind will be explained in the Fifth Part. But I would here remark that I

consider that a body undergoes death, when the proportion of motion and

rest which obtained mutually among its several parts is changed. For I do

not venture to deny that a human body, while keeping the circulation of

the blood and other properties, wherein the life of a body is thought to

consist, may none the less be changed into another nature totally different

from its own. There is no reason, which compels me to maintain that a body

does not die, unless it becomes a corpse; nay, experience would seem to

point to the opposite conclusion. It sometimes happens, that a man

undergoes such changes, that I should hardly call him the same. As I have

heard tell of a certain Spanish poet, who had been seized with sickness,

and though he recovered therefrom yet remained so oblivious of his past

life, that he would not believe the plays and tragedies he had

written to be his own: indeed, he might have been taken for a grown-up

child, if he had also forgotten his native tongue. If this instance seems

incredible, what shall we say of infants? A man of ripe age deems their

nature so unlike his own, that he can only be persuaded that he too has

been an infant by the analogy of other men. However, I prefer to leave such

questions undiscussed, lest I should give ground to the superstitious for

raising new issues.

Prop. XL. Whatsoever conduces to man's

social life, or causes men to live

together in harmony, is useful, whereas

whatsoever brings discord into a State is bad.

Proof.- For whatsoever causes men to live together in harmony also causes

them to live according to reason (IV:xxxv.), and is therefore (IV:xxvi.

and IV:xxvii.) good, and (for the same reason) whatsoever brings about

discord is bad. Q.E.D.

Prop. XLI. Pleasure in itself is not

bad but good: contrariwise, pain in

itself is bad.

Proof.- Pleasure (III:xi.&Note) is emotion, whereby the body's power of

activity is increased or helped; pain is emotion, whereby the body's power

of activity is diminished or checked; therefore (IV:xxxviii.) pleasure in

itself is good, &c. Q.E.D.

Prop. XLII. Mirth cannot be excessive,

but is always good; contrariwise,

Melancholy is always bad.

Proof.- Mirth (see its Def. in III:xi.Note) is pleasure. which, in so

far as it is referred to the body, consists in all parts of the body being

affected equally: that is (III:xi.), the body's power of activity is

increased or aided in such a manner, that the several parts maintain their

former proportion of motion and rest; therefore Mirth is always good

(IV. xxxix.), and cannot be excessive. But Melancholy (see its Def. in

the same note to III:xi.Note) is pain, which, in so far as it is referred

to the body, consists in the absolute decrease or hindrance of the body's

power of activity; therefore (IV:xxxviii.) it is always bad. Q.E.D.

Prop. XLIII. Stimulation may be excessive

and bad; on the other hand, grief may be

good, in so far as stimulation or pleasure

is bad.

Proof.- Localized pleasure or stimulation (titillatio) is pleasure, which,

in so far as it is referred to the body, consists in one or some of its

parts being affected more than the rest (see its Definition, III:xi.Note);

the power of this emotion may be sufficient to overcome other actions of

the body (IV:vi.), and may remain obstinately fixed therein, thus rendering

it incapable of being affected in a variety of other ways: therefore

(IV:xxxviii.) it may be bad. Again, grief, which is pain, cannot as such

be good (IV:xli.). But, as its force and increase is defined by the power

of an external cause compared with our own (IV:v.), we can conceive

infinite degrees and modes of strength in this emotion (IV:iii.);

we can, therefore, conceive it as capable of restraining stimulation,

and preventing its becoming excessive, and hindering the body's

capabilities; thus, to this extent, it will be good. Q.E.D.

Prop. XLIV. Love and desire may be excessive.

Proof.- Love is pleasure, accompanied by the idea of an external cause

(Def_of_Emotions:vi.); therefore stimulation, accompanied by the idea of

an external cause is love (III:xi.Note); hence love maybe excessive.

Again, the strength of desire varies in proportion to the emotion from

which it arises (III:xxxvii.). Now emotion may overcome all the rest of

men's actions (IV:vi.); so, therefore, can desire, which arises from the

same emotion, overcome all other desires, and become excessive, as we

showed in the last proposition concerning stimulation.

Note.- Mirth, which I have stated to be good, can be conceived more easily

than it can be observed. For the emotions, whereby we are daily assailed,

are generally referred to some part of the body which is affected more than

the rest; hence the emotions are generally excessive, and so fix the mind

in the contemplation of one object, that it is unable to think of others;

and although men, as a rule, are a prey to many emotions - and very few

are found who are always assailed by one and the same - yet there are

cases, where one and the same emotion remains obstinately fixed. We

sometimes see men so absorbed in one object, that, although it be not

present, they think they have it before them; when this is the case with a

man who is not asleep, we say he is delirious or mad; nor are those persons

who are inflamed with love, and who dream all night and all day about

nothing but their mistress, or some woman, considered as less mad, for

they are made objects of ridicule. But when a miser thinks of nothing but

gain or money, or when an ambitious man thinks of nothing but glory, they

are not reckoned to be mad, because they are generally harmful, and are

thought worthy of being hated. But, in reality, Avarice, Ambition, Lust,

&c., are species of madness, though they may not be reckoned among diseases.

Prop. XLV. Hatred can never be good.

Proof.- When we hate a man, we endeavour to destroy him (III.xxxix.),

that is (IV:xxxvii.), we endeavour to do something that is bad.

Therefore, &c. Q.E.D.

N.B. Here, and in what follows, I mean by hatred only hatred towards men.

Corollary I.- Envy, derision, contempt, anger, revenge, and other emotions

attributable to hatred, or arising therefrom, are bad; this is evident from

III:xxxix. and IV:xxxvii.

Corollary II.- Whatsoever we desire from motives of hatred is base, and in

a State unjust. This also is evident from III:xxxix., and from the

definitions of baseness and injustice in IV:xxxvii.Note.

Note.- Between derision (which I have in Coroll. I. stated to be bad) and

laughter I recognize a great difference. For laughter, as also jocularity,

is merely pleasure; therefore, so long as it be not excessive, it is in

itself good (IV:xli.). Assuredly nothing forbids man to enjoy himself,

save grim and gloomy superstition. For why is it more lawful to satiate

one's hunger and thirst than to drive away one's melancholy? I reason, and

have convinced myself as follows: No deity, nor anyone else, save the

envious, takes pleasure in my infirmity and discomfort, nor sets down to my

virtue the tears, sobs, fear, and the like, which axe signs of infirmity of

spirit; on the contrary, the greater the pleasure wherewith we are affected,

the greater the perfection whereto we pass; in other words, the more must

we necessarily partake of the divine nature. Therefore, to make use of what

comes in our way, and to enjoy it as much as possible (not to the point of

satiety, for that would not be enjoyment) is the part of a wise man. I say

it is the part of a wise man to refresh and recreate himself with moderate

and pleasant food and drink, and also with perfumes, with the soft beauty

of growing plants, with dress, with music, with many sports, with theatres,

and the like, such as every man may make use of without injury to his

neighbour. For the human body is composed of very numerous parts, of

diverse nature, which continually stand in need of fresh and varied

nourishment, so that the whole body may be equally capable of performing

all the actions, which follow from the necessity of its own nature; and,

consequently, so that the mind may also be equally capable of -

understanding many things simultaneously. This way of life, then, agrees

best with our principles, and also with general practice; therefore, if

there be any question of another plan, the plan we have mentioned is the

best, and in every way to be commended. There is no need for me to set

forth the matter more clearly or in more detail.

Prop. XLVI. He, who lives under the

guidance of reason, endeavours, as

far as possible, to render back love,

or kindness, for other men's hatred,

anger, contempt, &c., towards him.

Proof.- All emotions of hatred are bad (IV:xlv.Coroll.i.); therefore he who

lives under the guidance of reason will endeavour, as far as possible, to

avoid being assailed by, such emotions (IV:xix.); consequently, he will

also endeavour to prevent others being so aspect (IV:xxxvii.). But hatred

is increased by being reciprocated, and can be quenched by love III:xliii.),

so that hatred may pass into love (III:xliv.); therefore he who lives under

the guidance of reason will endeavour to repay hatred with love, that is,

with kindness. Q.E.D.

Note.- He who chooses to avenge wrongs with hatred is assuredly, wretched.

But he, who strives to conquer hatred with love, fights his battle in joy

and confidence; he withstands many as easily as one, and has very little

need of fortune's aid. Those whom he vanquishes yield joyfully, not through

failure, but through increase in their powers; all these consequences

follow so plainly from the mere definitions of love and understanding,

that I have no need to prove them in detail.

Prop. XLVII. Emotions of hope and fear

cannot be in themselves good.

Proof.- Emotions of hope and fear cannot exist without pain. For fear is

pain (Def. of the Emotions:xiii.), and hope (Def. of the Emotions,

Explanation xii. and xiii.) cannot exist without fear; therefore (IV. xli.)

these emotions cannot be good in themselves, but only in so far as they

can restrain excessive pleasure (IV:xliii.). Q.E.D.

Note.- We may add, that these emotions show defective knowledge and an

absence of power in the mind; for the same reason confidence, despair, joy,

and disappointment are signs of a want of mental power. For although

confidence and joy are pleasurable emotions, they, nevertheless imply a

preceding, pain, namely, hope and fear. Wherefore the more we endeavour to

be guided by reason, the less do we depend on hope; we endeavour to free

ourselves from fear, and, as far as we can, to dominate fortune, directing

our actions by the sure counsels of wisdom.

Prop. XLVIII. The emotions of over-esteem

and disparagement are always bad.

Proof.- These emotions (see Def. of the Emotions, xxi., xxii.) are

repugnant to reason; and are therefore (IV. xxvi., IV:xxvii.) bad. Q.E.D.

Prop. XLIX. Over-esteem is apt to

render its object proud.

Proof.- If we see that any one rates us too highly, for love's sake,

we are apt to become elated (III:xli.), or to be pleasurably affected

Def. of the Emotions:xxx.); the good which we hear of ourselves we readily

believe (III:xxv.); and therefore, for love's sake, rate ourselves too

highly; in other words, we are apt to become proud. Q.E.D.

Prop. L. Pity, in a man who lives

under the guidance of reason, is in

itself bad and useless.

Proof.- Pity (Def. of the Emotions:xviii.) is a pain, and therefore

(IV:xli.) is in itself bad. The good effect which follows, namely, our

endeavour to free the object of our pity from misery, is an action which

we desire to do solely at the dictation of reason (IV:xxxvii.); only at

the dictation of reason are we able to perform any action, which we know

for certain to be good (IV:xxvii.); thus, in a man who lives under the

guidance of reason, pity in itself is useless and bad. Q.E.D.

Note.- He who rightly realizes, that all things follow from the necessity

of the divine nature, and come to pass in accordance with the eternal laws

and rules of nature, will not find anything worthy of hatred, derision, or

contempt, nor will he bestow pity on anything, but to the utmost extent of

human virtue he will endeavour to do well, as the saying is, and to rejoice.

We may add, that he, who is easily touched with compassion, and is moved by

another's sorrow or tears, often does something which he afterwards regrets;

partly because we can never be sure that an action caused by emotion is

good, partly because we are easily deceived by false tears. I am in this

place expressly speaking of a man living under the guidance of reason. He

who is moved to help others neither by reason nor by compassion, is

rightly styled inhuman, for (III: xxvii.) he seems unlike a man.

Prop. LI. Approval is not repugnant

to reason, but can agree therewith

and arise therefrom.

Proof.- Approval is love towards one who has done good to another (Def. of

the Emotions:xix.); therefore it may be referred to the mind, in so far as

the latter is active (III:lix.), that is (III:iii.), in so far as it -

understands; therefore, it is in agreement with reason, &c. Q.E.D.

Another Proof.- He, who lives under the guidance of reason, desires for

others the good which he seeks for himself (IV:xxxvii.); wherefore from

seeing someone doing good to his fellow his own endeavour to do good is

aided; in other words, he will feel pleasure (III:xi.Note) accompanied by

the idea of the benefactor. Therefore he approves of him. Q.E.D.

Note.- Indignation as we defined it (Def. of the Emotions:xx.) is

necessarily evil (IV:xlv.); we may, however, remark that, when the

sovereign power for the sake of preserving peace punishes a citizen

who has injured another, it should not be said to be indignant with the

criminal, for it is not incited by hatred to ruin him, it is led by a sense

of duty to punish him.

Prop. LII. Self-approval may arise

from reason, and that which arises

from reason is the highest possible.

Proof.- Self-approval is pleasure arising from a man's contemplation of

himself and his own power of action (Def. of the Emotions:xxv.). But a

man's true power of action - or virtue is reason herself (III:iii.), as

the said man clearly and distinctly contemplates her (II:xl., II:xliii.);

therefore self-approval arises from reason. Again, when a man is

contemplating himself, he only perceived clearly and distinctly or

adequately, such things as follow from his power of action (III:Def.ii.),

that is (III:iii.), from his power of understanding; therefore in such

contemplation alone does the highest possible self-approval arise. Q.E.D.

Note.- Self-approval is in reality the highest object for which we can hope.

For (as we showed in IV:xxv.) no one endeavours to preserve his being for

the sake of any ulterior object, and, as this approval is more and more

fostered and strengthened by praise (III:liii.Coroll.), and on the

contrary (III:lv.Coroll.) is more and more disturbed by blame, fame

becomes the most powerful of incitements to action, and life under

disgrace is almost unendurable.

Prop. LIII. Humility is not a virtue,

or does not arise from reason.

Proof.- Humility is pain arising from a man's contemplation of his own

infirmities (Def. of the Emotions:xxvi.). But, in so far as a man knows

himself by true reason, he is assumed to understand his essence, that is,

his power (III:vii.). Wherefore, if a man in self-contemplation perceives

any infirmity in himself, it is not by virtue of his understanding himself,

but (III:lv.) by virtue of his power of activity being checked. But, if we

assume that a man perceives his own infirmity by virtue of understanding

something stronger than himself, by the knowledge of which he determines

his own power of activity, this is the same as saying that we conceive

that a man understands himself distinctly (IV:xxvi.), because (Land reads:

"Quod ipsius agendi potentia juvatur"- which I have translated above. He -

suggests as alternative readings to `quod', 'quo' (= whereby) and 'quodque'

(= and that).) his power of activity is aided. Wherefore humility, or the

pain which arises from a man's contemplation of his own infirmity, does

not arise from the contemplation or reason, and is not a virtue but a

passion. Q.E.D.

Prop. LIV. Repentance is not a virtue,

or does not arise from reason ; but he

who repents of an action is doubly

wretched or infirm.

Proof.- The first part of this proposition is proved like the foregoing

one. The second part is proved from the mere definition of the emotion in

question (Def. of the Emotions:xxvii.). For the man allows himself to be

overcome, first, by evil desires; secondly, by pain.

Note.- As men seldom live under the guidance of reason, these two emotions,

namely, Humility and Repentance, as also Hope and Fear, bring more good

than harm; hence, as we must sin, we had better sin in that direction.

For, if all men who are a prey to emotion were all equally proud, they

would shrink from nothing, and would fear nothing; how then could they be

joined and linked together in bonds of union? The crowd plays the tyrant,

when it is not in fear; hence we need not wonder that the prophets, who

consulted the good, not of a few, but of all, so strenuously commended

Humility, Repentance, and Reverence. Indeed those who are a prey to these

emotions may be led much more easily than others to live under the

guidance of reason, that is, to become free and to enjoy the life of the

blessed.

Prop. LV. Extreme pride or dejection

indicates extreme ignorance of self.

Proof.- This is evident from Def. of the Emotions:xxviii. and xxix.

Prop. LVI. Extreme pride or dejection

indicates extreme infirmity of spirit.

Proof.- The first foundation of virtue is self-preservation

(IV:xxii.Coroll.) under the guidance of reason (IV:xxiv.). He, therefore,

who is ignorant of himself, is ignorant of the foundation of all virtues,

and consequently of all virtues. Again, to act virtuously is merely to

act under the guidance of reason (IV:xxiv.): now he, that acts under the

guidance of reason, must necessarily know that he so acts (III:xliii.).

Therefore he who is in extreme ignorance of himself, and consequently of

all virtues, acts least in obedience to virtue; in other words

(IV:Def.viii.), is most infirm of spirit. Thus extreme pride or dejection

indicates extreme infirmity of spirit. Q.E.D.

Corollary.- Hence it most clearly follows, that the proud and the

dejected specially fall a prey to the emotions.

Note.- Yet dejection can be more easily corrected than pride; for the

latter being a pleasurable emotion, and the former a painful emotion, the

pleasurable is stronger than the painful (IV:xviii.).

Prop. LVII. The proud man delights in the

company of flatterers and parasites,

but hates the company of the high-minded.

Proof.- Pride is pleasure arising from a man's over estimation of himself

(Def. of the Emotions:xxviii. and vi.); this estimation the proud man will

endeavour to foster by all the means in his power (III:xiii.Note); he will

therefore delight in the company of flatterers and parasites (whose

character is too well known to need definition here), and will avoid the

company of high-minded men, who value him according to his deserts. Q.E.D.

Note.- It would be too long a task to enumerate here all the evil results

of pride, inasmuch as the proud are a, prey to all the emotions, though to

none of them less than to love and pity. I cannot, however, pass over in

silence the fact, that a man may be called proud from his underestimation

of other people; and, therefore, pride in this sense may be defined as

pleasure arising from the false opinion, whereby a man may consider

himself superior to his fellows. The dejection, which is the opposite

quality to this sort of pride, may be defined as pain arising from the

false opinion, whereby a man may think himself inferior to his fellows.

Such being the ease, we can easily see that a proud man is necessarily

envious (III:xli.Note), and only takes pleasure in the company, who fool

his weak mind to the top of his bent, and make him insane instead of

merely foolish.

Though dejection is the emotion contrary to pride, yet is the dejected

man very near akin to the proud man. For, inasmuch as his pain arises

from a comparison between his own infirmity and other men's power or

virtue, it will be removed, or, in other words, he will feel pleasure, if

his imagination be occupied in contemplating other men's faults; whence

arises the proverb, "The unhappy are comforted by finding fellow-sufferers."

Contrariwise, he will be the more pained in proportion as he thinks

himself inferior to others; hence none are so prone to envy as the

dejected, they are specially keen in observing men's actions, with a

view to fault-finding rather than correction, in order to reserve their

praises for dejection, and to glory therein, though all the time with a

dejected air. These effects follow as necessarily from the said emotion,

as it follows from the nature of a triangle, that the three angles are

equal to two right angles. I have already said that I call these and

similar emotions bad, solely in respect to what is useful to man. The

laws of nature have regard to nature's general order, whereof man is but

a part. I mention this, in passing, lest any should think that I have

wished to set forth the faults and irrational deeds of men rather than

the nature and properties of things. For, as I said in the preface to the

third Part, I regard human emotions and their properties as on the same

footing with other natural phenomena. Assuredly human emotions indicate

the power and ingenuity, of nature, if not of human nature, quite as fully,

as other things which we admire, and which we delight to contemplate.

But I pass on to note those qualities in the emotions, which bring

advantage to man, or inflict injury upon him.

Prop. LVIII. Honour (gloria) is not repugnant

to reason, but may arise therefrom.

Proof.-This is evident from Def. of the Emotions:xxx., and also from the

definition of an honourable man (IV:xxxvii.Note.i.).

Note.- Empty honour, as it is styled, is self- approval, fostered only by

the good opinion of the populace; when this good opinion ceases there

ceases also the self-approval, in other words, the highest object of each

man's love (IV:lii.Note); consequently, he whose honour is rooted in

popular approval must, day by day, anxiously strive, act, and scheme in

order to retain his reputation. For the populace is variable and

inconstant, so that, if a reputation be not kept up, it quickly withers

away. Everyone wishes to catch popular applause for himself, and readily

represses the fame of others. The object of the strife being estimated as

the greatest of all goods, each combatant is seized with a fierce desire

to put down his rivals in every possible way, till he who at last comes

out victorious is more proud of having done harm to others than of having

done good to himself. This sort of honour, then, is really empty, being

nothing.

The points to note concerning shame (pudor) may easily be inferred

from what was said on the subject of mercy and repentance. I will only

add that shame, like compassion, though not a virtue, is yet good, in so

far as it shows, that the feeler of shame is really imbued with the

desire to live honourably; in the same way as suffering is good, as

showing that the injured part is not mortified. Therefore, though a man

who feels shame is sorrowful, he is yet more perfect than he, who is

shameless, and has no desire to live honourably.

Such are the points which I undertook to remark upon concerning the

emotions of pleasure and pain; as for the desires, they are good or bad

according as they spring from good or evil emotions. But all, in so far

as they are engendered in us by, emotions wherein the mind is passive,

are blind (as is evident from what was said in IV:xliv.Note), and would

be useless, if men could easily, be induced to live by the guidance of

reason only, as I will now briefly, show.

Prop. LIX. To all the actions, whereto we

are determined by emotion wherein the mind

is passive; we can be determined without

emotion by reason.

Proof.- To act rationally, is nothing else (III:iii. and III:Def.ii.)

but to perform those actions, which follow from the necessity, of our

nature {to persist} considered in itself alone. But pain is bad, in so

far as it diminishes or checks the power of action (IV:xli.); wherefore

we cannot by pain be determined to any action, which we should be unable

to perform under the guidance of reason. Again, pleasure is bad only

in so far as it hinders a man's capability for action (IV:xli., IV:xliii.);

therefore to this extent we could not be determined by, it to any action,

which we could not perform under the guidance of reason. Lastly, pleasure,

in so far as it is good, is in harmony with reason (for it consists in the

fact that a man's capability for action is increased or aided); nor is the

mind passive therein, except in so far as a man's power of action is not

increased to the extent of affording him an adequate conception of

himself and his actions (III:iii., &Note).

Wherefore, if a man who is pleasurably affected be brought to such a

state of perfection, that he gains an adequate conception of himself and

his own actions, he will be equally, nay more, capable of those actions,

to which he is determined by emotion wherein the mind is passive. But all

emotions are attributable to pleasure, to pain, or to desire (Def. of the

Emotions:iv. explanation); and desire (Def. of the Emotions:i.) is nothing

else but the attempt to act; therefore, to all actions, &c. Q.E.D.

Another Proof.- A given action is called bad, in so far as it arises

from one being affected by hatred or any evil emotion. But no action,

considered in itself alone, is either good or bad (as we pointed out in

the preface to Pt. IV.), one and the same action being sometimes good,

sometimes bad; wherefore to the action which is sometimes bad, or arises

from some evil emotion, we may be led by reason (IV:xix.). Q.E.D.

Note.- An example will put this point in a clearer light. The action of

striking, in so far as it is considered physically, and in so far as we

merely look to the fact that a man raises his arm, clenches his fist, and

moves his whole arm violently downwards, is a virtue or excellence which

is conceived as proper to the structure of the human body. If, then, a man,

moved by anger or hatred, is led to clench his fist or to move his arm,

this result takes place (as we showed in Pt.II.), because one and the

same action can be associated with various mental images of things;

therefore we may be determined to the performance of one and the same

action by confused ideas, or by clear and distinct ideas. Hence it is

evident that every desire which springs from emotion, wherein the mind is

passive, would become useless, if men could be guided by reason. Let us

now see why desire which arises from emotion, wherein the mind is passive,

is called by us blind.

Prop. LX. Desire arising from a pleasure

or pain, that is not attributable, to

the whole body, but only to one or certain

parts thereof, is without utility in

respect to a man as a whole.

Proof.- Let it be assumed, for instance, that A, a part of a body, is so

strengthened by some external cause, that it prevails over the remaining

parts (IV:vi.). This part will not endeavour to do away with its own

powers, in order that the other parts of the body may perform its office;

for this it would be necessary for it to have a force or power of doing

away with its own powers, which (III:vi.) is absurd. The said part, and,

consequently, the mind also, will endeavour to preserve its condition.

Wherefore desire arising from a pleasure of the kind aforesaid has no

utility in reference to a man as a whole. If it be assumed, on the other

hand, that the part, A, be checked so that the remaining parts prevail,

it may be proved in the same manner that desire arising from pain has no

utility in respect to a man as a whole. Q.E.D.

Note.- As pleasure is generally (IV:xliv.Note) attributed to one part

of the body, we generally desire to preserve our being with out taking

into consideration our health as a whole: to which it may be added, that

the desires which have most hold over us (IV:ix.) take account of the

present and not of the future.

Prop. LXI. Desire which springs from

reason cannot be excessive.

Proof.- Desire (Def. of the Emotions:i.) considered absolutely is the

actual essence of man, in so far as it is conceived as in any way

determined to a particular activity by some given modification of itself.

Hence desire, which arises from reason, that is (III:iii.), which is

engendered in us in so far as we act, is the actual essence or nature of

man, in so far as it is conceived as determined to such activities as are

adequately conceived through man's essence only (III:Def.ii.). Now, if

such desire could be excessive, human nature considered in itself alone

would be able to exceed itself, or would be able to do more than it can,

a manifest contradiction. Therefore, such desire cannot be excessive. Q.E.D.

Prop. LXII. In so far as the mind conceives

a thing under the dictates of reason, it is

affected equally, whether the idea be of a

thing future, past, or present.

Proof.- Whatsoever the mind conceives under the guidance of reason, it

conceives under the form of eternity or necessity (II:xliv.Coroll.ii.),

and is therefore affected with the same certitude (II:xliii.&Note).

Wherefore, whether the thing be present, past, or future, the mind

conceives it under the same necessity and is affected with the same

certitude; and whether the idea be of something present, past, or future,

it will in all cases be equally true (II:xli.); that is, it will always

possess the same properties of an adequate idea (II:Def.iv.); therefore, in

so far as the mind conceives things under the dictates of reason, it is

affected in the same manner, whether the idea be of a thing future, past,

or present. Q.E.D.

Note.- If we could possess an adequate knowledge of the duration of things,

and could determine by reason their periods of existence, we should

contemplate things future with the same emotion as things present; and

the mind would desire as though it were present the good which it

conceived as future; consequently it would necessarily neglect a lesser

good in the present for the sake of a greater good in the future, and

would in no wise desire that which is good in the present but a source of

evil in the future, as we shall presently show. However, we can have but

a very inadequate knowledge of the duration of things (II:xxxi.) and the

periods of their existence (II:xliv.Note) we can only determine by

imagination, which is not so powerfully affected by the future as by the

present. Hence such true knowledge of good and evil as we possess is

merely abstract or general, and the judgment which we pass on the order

of things and the connection of causes, with a view to determining what

is good or bad for us in the, present, is rather imaginary than real.

Therefore it is nothing wonderful, if the desire arising from such

knowledge of good and evil, in so far as it looks on into the future, be

more readily checked than the desire of things which are agreeable at the

present time. (Cf. IV:xvi.)

Prop. LXIII. He who is led by fear,

and does good in order to escape evil,

is not led by reason.

Proof.- All the emotions which are attributable to the mind as active,

or in other words to reason, are emotions of pleasure and desire (III:lix.);

therefore, he who is led by fear, and does good in order to escape evil,

is not led by reason.

Note.- Superstitions persons, who know better how to rail at vice than

how to teach virtue, and who strive not to guide men by reason, but so

to restrain them that they would rather escape evil than love virtue,

have no other aim but to make others as wretched as themselves; wherefore

it is nothing wonderful, if they be generally troublesome and odious to

their fellow-men.

Corollary.- Under desire which springs from reason, we seek good directly,

and shun evil indirectly.

Proof.- Desire which springs from reason can only spring from a pleasurable

emotion, wherein the mind is not passive (III:lix.), in other words, from

a pleasure which cannot be excessive (IV:lxi.), and not from pain;

wherefore this desire springs from the knowledge of good, not of evil

(IV:viii.); hence under the guidance of reason we seek good directly and

only by implication shun evil. Q.E.D.

Note.- This Corollary may be illustrated by the example of a sick and a

healthy man. The sick man through fear of death eats what he naturally

shrinks from, but the healthy man takes pleasure in his food, and thus

gets a better enjoyment out of life, than if he were in fear of death,

and desired directly to avoid it. So a judge, who condemns a criminal

to death, not from hatred or anger but from love of the public

well-being, is guided solely by reason.

Prop. LXIV. The knowledge of evil is

an inadequate knowledge.

Proof.- The knowledge of evil (IV:viii.) is pain, in so far as we are

conscious thereof. Now pain is the transition to a lesser perfection

(Def. of the Emotions:iii.) and therefore cannot be understood through

man's nature (III:vi.,& II:vii.); therefore it is a passive state

(III.Def.ii.) which (III:iii.) depends on inadequate ideas; consequently

the knowledge thereof (II:xxix.), namely, the knowledge of evil, is

inadequate. Q.E.D.

Corollary.- Hence it follows that, if the human mind possessed only

adequate ideas, it would form no conception of evil.

Prop. LXV. Under the guidance of reason we

should pursue the greater of two goods and

the lesser of two evils.

Proof.- A good which prevents our enjoyment of a greater good is in

reality an evil; for we apply the terms good and bad to things, in so

far as we compare them one with another (see preface to this Part);

therefore, evil is in reality a lesser good; hence under the guidance of

reason we seek or pursue only the greater good and the lesser evil. Q.E.D.

Corollary.- We may, under the guidance of reason, pursue the lesser evil

as though it were the greater good, and we may shun the lesser good,

which would be the cause of the greater evil. For the evil, which is

here called the lesser, is really good, and the lesser good is really

evil, wherefore we may seek the former and shun the latter. Q.E.D.

Prop. LXVI. We may, under the guidance of

reason, seek a greater good in the future

in preference to a lesser good in the

present, and we may seek a lesser evil in

the present in preference to a greater evil

in the future.

"Maltim praesens minus prae majori futuro." (Van Vloten). Bruder reads: "Malum praesens minus, quod

causa est faturi alicujus mali." The last word of the latter is an obvious misprint, and is

corrected by the Dutch translator into "majoris boni." (Pollock, p. 268, note.)

Proof.- If the mind could have an adequate knowledge of things future,

it would be affected towards what is future in the same way as towards

what is present (IV:lxii.); wherefore, looking merely to reason, as in

this proposition we are assumed to do, there is no difference, whether

the greater good or evil be assumed as present, or assumed as future;

hence (IV:lxv.) we may seek a greater good in the future in preference

to a lesser good in the present, &c. Q.E.D.

Corollary.- We may, under the guidance of reason, seek a lesser evil in

the present, because it is the cause of a greater good in the future,

and we may shun a lesser good in the present, because it is the cause

of a greater evil in the future. This Corollary is related to the

foregoing Proposition as the Corollary to IV:lxv. is related to the

said IV:lxv.

Note.- If these statements be compared with what we have pointed out

concerning the strength of the emotions in this Part up to Prop. xviii.,

we shall readily see the difference between a man, who is led solely by

emotion or opinion, and a man, who is led by reason. The former, whether

will or no, performs actions whereof he is utterly ignorant; the latter is

his own master and only performs such actions, as he knows are of primary

importance in life, and therefore chiefly, desires; wherefore I call the

former a slave, and the latter a free man, concerning whose disposition

and manner of life it will be well to make a few observations.

Prop. LXVII. A free man thinks of death

least of all things; and his wisdom is

a meditation not of death but of life.

Proof.- A free man is one who lives under the guidance of reason, who is

not led by fear (IV:lxiii.), but who directly desires that which is good

(IV:lxiii.Coroll.), in other words (IV:xxiv.), who strives to act, to live,

and to preserve his being on the basis of seeking his own true advantage;

wherefore such an one thinks of nothing less than of death, but his wisdom

is a meditation of life. Q.E.D

Prop. LXVIII. If men were born free,

they would, so long as they remained free,

form no conception of good and evil.

Proof.- I call free him who is led solely by reason; he, therefore, who

is born free, and who remains free, has only adequate ideas; therefore

(IV:lxiv.Coroll.) he has no conception of evil, or consequently (good

and evil being correlative) of good. Q.E.D.

Note.- It is evident, from IV:iv., that the hypothesis of this Proposition

is false and inconceivable, except in so far as we look solely to the

nature of man, or rather to God; not in so far as the latter is infinite,

but only in so far as he is the cause of man's existence.

This, and other matters which we have already proved, seem to have

been signifieded by Moses in the history of the first man. For in that

narrative no other power of God is conceived, save that whereby he

created man, that is the power wherewith he provided solely for man's

advantage; it is stated that God forbade man, being free, to eat of the

tree of the knowledge of good and evil, and that, as soon as man should

have eaten of it, he would straightway fear death rather than desire to

live. Further, it is written that when man had found a wife, who was in

entire harmony with his nature, he knew that there could be nothing in

nature which could be more useful to him; but that after he believed the

beasts to be like himself, he straightway began to imitate their emotions

(III:xxvii.), and to lose his freedom; this freedom was afterwards

recovered by the patriarchs, led by the spirit of Christ; that is, by the

idea of God, whereon alone it depends, that man may be free, and desire for

others the good which he desires for himself, as we have shown above

(IV:xxxii.).

Prop. LXIX. The virtue of a free man is seen

to be as great, when it declines dangers,

as when it overcomes them.

Proof.- Emotion can only be checked or removed by an emotion contrary to

itself, and possessing more power in restraining emotion (IV:vii.). But

blind daring and fear are emotions, which can be conceived as equally

great (IV:v. and IV:iii.): hence, no less virtue or firmness is required

in checking daring than in checking fear (III:lix.Note); in other words

(Def. of the Emotions:xl. and xli.), the free man shows as much virtue,

when he declines dangers, as when he strives to overcome them. Q.E.D.

Corollary.- The free man is as courageous in timely retreat as in combat;

or, a free man shows equal courage or presence of mind, whether he elect

to give battle or to retreat.

Note.- What courage (animositas) is, and what I mean thereby, I explained

in III:lix.Note. By danger I mean everything, which can give rise to any

evil, such as pain, hatred, discord, &c.

Prop. LXX. The free man, who lives among the

ignorant, strives, as far as he can, to avoid

receiving favours from them.

Proof.- Everyone judges what is good according to his disposition

(III:xxxix.Note); wherefore an ignorant man, who has conferred a benefit

on another, puts his own estimate upon it, and, if it appears to be

estimated less highly by the receiver, will feel pain (III:xlii.). But

the free man only desires to join other men to him in friendship

(IV:xxxvii.), not repaying their benefits with others reckoned as of like

value, but guiding himself and others by the free decision of reason,

and doing only such things as he knows to be of primary importance.

Therefore the free man, lest be should become hateful to the ignorant, or

follow their desires rather than reason, will endeavour, as far as he can,

to avoid receiving their favours.

Note.- I say, as far as he can. For though men be ignorant, yet are they

men, and in cases of necessity could afford us human aid, the most

excellent of all things: therefore it is often necessary to accept favours

from them, and consequently to repay such favours in kind; we must,

therefore, exercise caution in declining favours, lest we should have the

appearance of despising those who bestow them, or of being, from

avaricious motives, unwilling to requite them, and so give ground for

offence by the very fact of striving to avoid it. Thus, in declining

favours, we must look to the requirements of utility and courtesy.

Prop. LXXI. Only free men are thoroughly

grateful one to another.

Proof.- Only free men are thoroughly useful one to another, and

associated among themselves by the closest necessity of friendship

(IV:xxxv.,&Coroll.i.), only such men endeavour, with mutual zeal of

love, to confer benefits on each other (IV:xxxvii.), and, therefore,

only they are thoroughly grateful one to another. Q.E.D.

Note.- The goodwill, which men who are led by blind desire have for one

another, is generally a bargaining or enticement, rather than pure goodwill.

Moreover, ingratitude is not an emotion. Yet it is base, inasmuch as

it generally shows, that a man is affected by excessive hatred, anger,

pride, avarice, &c. He who, by reason of his folly, knows not how to

return benefits, is not ungrateful, much less he who is not gained over

by the gifts of a courtesan to serve her lust, or by a thief to conceal

his thefts, or by any similar persons. Contrariwise, such an one shows

a constant mind, inasmuch as he cannot by an gifts be corrupted, to his

own or the general hurt.

Prop. LXXII. The free man never acts fraudulently,

but always in good faith.

Proof.- If it be asked: What should a man's conduct be in a case where

he could by breaking faith free himself from the danger of present death?

Would not his plan of self-preservation completely persuade him to deceive?

This may be answered by pointing out that, if reason persuaded him to act

thus, it would persuade all men to act in a similar manner, in which case

reason would persuade men not to agree in good faith to unite their forces,

or to have laws in common, that is, not to. have any general laws, which is

absurd.

Prop. LXXIII. The man, who is guided by reason,

is more free in a State, where he lives under

a general system of law, than in

solitude, where he is independent.

Proof.- The man, who is guided by reason, does not obey through fear

(IV:Ixiii.): but, in so far as he endeavours to preserve his being

according to the dictates of reason, that is (IV:lxvi.Note), in so far

as he endeavours to live in freedom, he desires to order his life

according to the general good (IV:xxxvii.), and, consequently (as we

showed in IV:xxxvii.Note.ii.), to live according to the laws of his

country. Therefore the free man, in order to enjoy greater freedom,

desires to possess the general rights of citizenship. Q.E.D.

Note.- These and similar observations, which we have made on man's true

freedom, may be referred to strength, that is, to courage and nobility

of character (III:lix.Note). I do not think it worth while to prove

separately all the properties of strength; much less need I show, that he

that is strong hates no man, is angry with no man, envies no man, is

indignant with no man, despises no man, and least of all things is proud.

These propositions, and all that relate to the true way of life and

religion, are easily proved from IV:xxxvii. and IV:xlvi.; namely, that

hatred should be overcome with love, and that every man should desire for

others the good which he seeks for himself. We may also repeat what

we drew attention to in the note to IV:I., and in other places; namely,

that the strong man has ever first in his thoughts, that all things

follow from the necessity of the divine nature; so that whatsoever he

deems to be hurtful and evil, and whatsoever, accordingly, seems to him

impious, horrible, unjust, and base, assumes that appearance owing to his

own disordered, fragmentary, and confused view of the universe. Wherefore

he strives before all things to conceive things as they really are, and

to remove the hindrances to true knowledge, such as are hatred, anger,

envy, derision, pride, and similar emotions, which I have mentioned above.

Thus he endeavours, as we said before, as far as in him lies, to do good,

and to go on his way rejoicing. How far human virtue is capable of

attaining to such a condition, and what its powers may be, I will prove

in the following Part.

APPENDIX.

What have said in this Part concerning the right way of life has not been

arranged, so as to admit of being seen at one view, but has been set forth

piece-meal, according as I thought each Proposition could most readily be

deduced from what preceded it. I propose, therefore, to rearrange my

remarks and to bring them under leading heads.

I. All our endeavours or desires so follow from the necessity of our

nature, that they can be understood either through it alone, as their

proximate cause, or by virtue of our being a part of nature, which cannot

be adequately conceived through itself without other individuals.

II. Desires, which follow from our nature in such a manner, that they can

be understood through it alone, are those which are referred to the mind,

in so far as the latter is conceived to consist of adequate ideas: the

remaining desires are only referred to the mind, in so far as it conceives

things inadequately, and their force and increase are generally defined

not by the power of man, but by the power of things external to us:

wherefore the former are rightly called actions, the latter passions, for

the former always indicate our power, the latter, on the other hand, show

our infirmity and fragmentary knowledge.

III. Our actions, that is, those desires which are defined by man's power

or reason, are always good. The rest maybe either good or bad.

IV. Thus in life it is before all things useful to perfect the

understanding or reason, as far as we can, and in this alone man's

highest happiness or blessedness consists, indeed blessedness is nothing

else but the contentment of spirit, which arises from the intuitive

knowledge of God: now, to perfect the understanding is nothing else

but to understand God, God's attributes, and the actions which follow

from the necessity of his nature. Wherefore of a man, who is led by reason,

the ultimate aim or highest desire, whereby he seeks to govern all his

fellows, is that whereby he is brought to the adequate conception of

himself and of all things within the scope of his intelligence.

V. Therefore, without intelligence there is not rational life: and things

are only good, in so far as they aid man in his enjoyment of the

intellectual life, which is defined by intelligence. Contrariwise,

whatsoever things hinder man's perfecting of his reason, and capability

to enjoy the rational life, are alone called evil.

VI. As all things whereof man is the efficient cause are necessarily good,

no evil can befall man except through external causes; namely, by virtue

of man being a part of universal nature, whose laws human nature is

compelled to, obey, and to conform to in almost infinite ways.

VII. It is impossible, that man should not be a part of nature, or that

he should not follow her general order; but if he be thrown among

individuals whose nature is in harmony with his own, his power of action

will thereby be aided and fostered, whereas, if he be thrown among such as

are but very little in harmony with his nature, he will hardly be able to

accommodate himself to them without undergoing a great change himself.

VIII. Whatsoever in nature we deem to be evil, or to be capable of

injuring our faculty for existing and enjoying the rational life, we may

endeavour to remove in whatever way seems safest to us; on the other hand,

whatsoever we deem to be good or useful for preserving our being, and

enabling us to enjoy the rational life, we may appropriate to our use and

employ as we think best. Everyone without exception may, by sovereign

right of nature, do whatsoever he thinks will advance his own interest.

IX. Nothing can be in more harmony with the nature of any given thing

than other individuals of the same species; therefore (cf. vii.) for man

in the preservation of his being and the enjoyment of the rational life

there is nothing more useful than his fellow-man who is led by reason.

Further, as we know not anything among individual things which is more

excellent than a man led by reason, no man can better display the power of

his skill and disposition, than in so training men, that they come at last

to live under the dominion of their own reason.

X. In so far as men are influenced by envy or any kind of hatred, one

towards another, they are at variance, and are therefore to be feared in

proportion, as they are more powerful than their fellows.

XI. Yet minds are not conquered by force, but by love and high-mindedness.

XII. It is before all things useful to men to associate their ways of life,

to bind themselves together with such bonds as they think most fitted to

gather them all into unity, and generally to do whatsoever serves to

strengthen friendship.

XIII. But for this there is need of skill and watchfulness. For men are

diverse (seeing that those who live under the guidance of reason are few),

yet are they generally envious and more prone to revenge than to sympathy.

No small force of character is therefore required to take everyone as he

is, and to restrain one's self from imitating the emotions of others. But

those who carp at mankind, and are more skilled in railing at vice than

in instilling virtue, and who break rather than strengthen men's

dispositions, are hurtful both to themselves and others. Thus many from

too great impatience of spirit, or from misguided religious zeal, have

preferred to live among brutes rather than among men; as boys or youths,

who cannot peaceably endure the chidings of their parents, will enlist as

soldiers and choose the hardships of war and the despotic discipline in

preference to the comforts of home and the admonitions of their father:

suffering any burden to be put upon them, so long as they may spite

their parents.

XIV. Therefore, although men are generally governed in everything by their

own lusts, yet their association in common brings many more advantages

than drawbacks. Wherefore it is better to bear patiently the wrongs they

may do us, and to strive to promote whatsoever serves to bring about

harmony and friendship.

XV. Those things, which beget harmony, are such as are attributable to

justice, equity, and honourable living. For men brook ill not only what is

unjust or iniquitous, but also what is reckoned disgraceful, or that a man

should slight the received customs of their society. For winning love those

qualities are especially necessary which have regard to religion and piety

(cf. IV:xxxvii.Notes.i., &.ii.; IV:xlvi.Note; and IV:lxxiii.Note).

XVI. Further, harmony is often the result of fear: but such harmony is

insecure. Further, fear arises from infirmity of spirit and moreover

belongs not to the exercise of reason: the same is true of compassion,

though this latter seems to bear a certain resemblance to piety.

XVII. Men are also gained over by liberality, especially such as have

not the means to buy what is necessary to sustain life. However, to give

aid to every poor man is far beyond the power and the advantage of any

private person. For the riches of any private person are wholly inadequate

to meet such a call. Again, an individual man's resources of character

are too limited for him to be able to make all men his friends. Hence

providing for the poor is a duty, which falls on the State as a whole,

and has regard only to the general advantage.

XVIII. In accepting favours, and in returning gratitude our duty must be

wholly different (cf. IV:lxx.Note; IV:lxxi. Note).

XIX. Again, meretricious love, that is, the lust of generation arising

from bodily beauty, and generally every sort of love, which owns anything

save freedom of soul as its cause, readily passes into hate; unless indeed,

what is worse, it is a species of madness; and then it promotes discord

rather than harmony (cf. III:xxxi.Coroll.).

XX. As concerning marriage, it is certain that this is in harmony with

reason, if the desire for physical union be not engendered solely by

bodily beauty, but also by the desire to beget children and to train them

up wisely; and moreover, if the love of both, to wit, of the man and of

the woman, is not caused by bodily beauty only, but also by freedom of soul.

XXI. Furthermore, flattery begets harmony; but only by means of the vile

offence of slavishness or treachery. None are more readily taken with

flattery than the proud, who wish to be first, but are not.

XXII. There is in abasement a spurious appearance of piety and

religion. Although abasement is the opposite to pride, yet is he that

abases himself most akin to the proud (IV:lvii.Note).

XXIII. Shame also brings about harmony, but only in such matters as cannot

be hid. Further, as shame is a species of pain, it does not concern the

exercise of reason.

XXIV. The remaining emotions of pain towards men are directly opposed

to justice, equity, honour, piety, and religion; and, although

indignation seems to bear a certain resemblance to equity, yet is life

but lawless, where every man may pass judgment on another's deeds, and

vindicate his own or other men's rights.

XXV. Correctness of conduct (modestia), that is, the desire of pleasing

men which is determined by reason, is attributable to piety (as we said

in IV:xxxvii.Note.i.). But, if it spring from emotion, it is ambition,

or the desire whereby, men, under the false cloak of piety, generally

stir up discords and seditions. For he who desires to aid his fellows.

either in word or in deed, so that they may together enjoy the highest

good, he, I say, will before all things strive to, win them over with

love: not to draw them into admiration, so that a system may be called

after his name, nor to give any cause for envy. Further, in his

conversation he will shrink from talking of men's faults, and will be

careful to speak but sparingly of human infirmity: but he will dwell at

length on human virtue or power, and the way whereby it may be perfected.

Thus will men be stirred not by fear, nor by aversion, but only by the

emotion of joy, to endeavour, so far as in them lies, to live in

obedience to reason.

XXVI. Besides men, we know of no particular thing in nature in whose mind

we may rejoice, and whom we can associate with ourselves in friendship or

any sort of fellowship; therefore, whatsoever there be in nature besides

man, a regard for our advantage does not call on us to preserve, but to

preserve or destroy according to its various capabilities, and to adapt

to our use as best we may.

XXVII. The advantage which we derive from things external to us, besides

the experience and knowledge which we acquire from observing them, and

from recombining their elements in different forms, is principally the

preservation of the body; from this point of view, those things are most

useful which can so feed and nourish the body, that all its parts may

rightly fulfil their functions. For, in proportion as the body is capable

of being affected in a greater variety of ways, and of affecting external

bodies in a great number of ways, so much the more is the mind capable of

thinking (IV:xxxviii., IV:xxxix.). But there seem to be very few things

of this kind in nature; wherefore for the due nourishment of the body we

must use many foods of diverse nature. For the human body is composed of

very many parts of different nature, which stand in continual need of

varied nourishment, so that the whole body may be equally capable of

doing everything that can follow from its own nature, and consequently

that the mind also may be equally capable of forming many perceptions.

XXVIII. Now for providing these nourishments the strength of each

individual would hardly suffice, if men did not lend one another mutual

aid. But money has furnished us with a token for everything: hence it is

with the notion of money, that the mind of the multitude is chiefly

engrossed: nay, it can hardly conceive any kind of pleasure, which is not

accompanied with the idea of money as cause.

XXIX. This result is the fault only of those, who seek money, not from

poverty or to supply their necessary, wants, but because they, have

learned the arts of gain, wherewith they bring themselves to great

splendour. Certainly they nourish their bodies, according to custom, but

scantily, believing that they lose as much of their wealth as they spend on

the preservation of their body. But they who know the true use of money,

and who fix the measure of wealth solely with regard to their actual needs,

live content with little.

XXX. As, therefore, those things are good which assist the various parts

of the body, and enable them to perform their functions; and as pleasure

consists in an increase of, or aid to, man's power, in so far as he is

composed of mind and body; it follows that all those things which bring

pleasure are good. But seeing that things do not work with the object of

giving us pleasure, and that their power of action is not tempered to suit

our advantage, and, lastly, that pleasure is generally referred to one

part of the body more than to the other parts; therefore most emotions of

pleasure (unless reason and watchfulness be at hand), and consequently the

desires arising therefrom, may become excessive. Moreover we may add that

emotion leads us to pay most regard to what is agreeable in the present,

nor can we estimate what is future with emotions equally vivid.

(IV:xliv.Note, and IV:lx.Note.)

XXXI. Superstition, on the other hand, seems to account as good all that

brings pain, and as bad all that brings pleasure. However, as we said

above (IV:xlv.Note), none but the envious take delight in my infirmity

and trouble. For the greater the pleasure whereby we are affected, the

greater is the perfection whereto we pass, and consequently the more do

we partake of the divine nature: no pleasure can ever be evil, which is

regulated by a true regard for our advantage. But contrariwise he, who is

led by fear and does good only to avoid evil, is not guided by reason.

Ap.XXXII. (1) But human power is extremely limited, and is infinitely

surpassed by the power of external causes; we have not, therefore, an

absolute power of shaping to our use those things which are without us.

Nevertheless, we shall bear with an equal mind all that happens to us

in contravention to the claims of our own advantage, so long as we are

conscious, that we have done our duty, and that the power which we possess

is not sufficient to enable us to protect ourselves completely;

remembering that we are a part of universal nature, and that we

follow her order. If we have a clear and distinct understanding of

this, that part of our nature which is defined by intelligence, in other

words the better part of ourselves, will assuredly acquiesce in what

befalls us, and in such acquiescence will endeavour to persist. For,

in so far as we are intelligent beings, we cannot desire anything save

that which is necessary, nor yield absolute acquiescence to anything,

save to that which is true: wherefore, in so far as we have a right

understanding of these things, the endeavour of the better part of

ourselves is in harmony with the order of nature as a whole.
