The study of the natural limits of the faculties of the mind, has,

indeed, sometimes been misrepresented, as favouring a tendency to vague

and unlimited doubt on all subjects, even on those most important to

individual and social happiness; as if the great names, to which we

have long given our admiration, for the light which they have thrown

on the powers and weaknesses of the human understanding, were not also

the very names which we have been accustomed, not to admire merely, but

to venerate, for excellence of a still nobler kind. Far from leading

to general scepticism, it is, on the contrary, a sound study of the

principles of our intellectual and moral nature, which alone can free

from the danger of it. If the sceptical philosophy be false, as the

assertors of this objection will allow that it most assuredly is, it

can be overcome and destroyed only by a philosophy that is true;

and the more deeply, and the more early, the mind is embued with the

principles of truth, the more confidently may we rely on its rejection

of the errors that are opposed to them. It is impossible for one,

who is not absolutely born to labour, to pass through life without

forming, in his own mind, occasionally, some imperfect reflections on

the faculties by which he perceives and reasons; or without catching,

from those with whom he may associate, some of those vague notions, of

a vague philosophy, which pass unexamined from mind to mind, and become

current in the very colloquial language of the day. The alternatives,

therefore, (if we can, indeed, think of any other alternative when

truth is one,) are not those of knowledge and absolute ignorance of

the mental phenomena, but of knowledge more or less accurate; because

absolute ignorance, even though it were a state to be wished, is

beyond our power to preserve, in one who enjoys, in any respects, the

benefit of education and liberal society. We might, with much greater

prospect of success, attempt, by merely keeping from his view all

professed treatises on Astronomy, to prevent him from acquiring that

slight and common acquaintance with the system of the heavenly bodies,

which is necessary for knowing that the sun does not go round the

earth, than we could hope to prevent him from forming, or receiving,

some notions, accurate or inaccurate, as to the nature of mind; and

we surely cannot suppose, that the juster those opinions are, as to

the nature and force of the principles of belief, the feebler must the

principles of belief appear. It is not so, that nature has abandoned

us, with principles which we must fear to examine, and with truths and

illusions which we must never dare to separate. In teaching us what our

powers are incapable of attaining, she has at the same time, taught

us what truths they may attain; and within this boundary, we have the

satisfaction of knowing, that she has placed all the truths that are

important for our virtue and happiness. He, whose eyes are the clearest

to distinguish the bounding circle, cannot surely, be the dullest to

perceive the truths that are within. To know only to doubt, is but the

first step in philosophy; and to rest at this first step, is either

imbecility or idleness. It is not there that Wisdom sees, and compares,

and pronounces; it is Ignorance, that, with dazzled eyes, just opening

from the darkness of the night, perceives that she has been dreaming,

without being able to distinguish, in the sunshine, what objects

really existing are around. He alone is the philosopher truly awake,

who knows both how to doubt, and how to believe; believing what is

evident on the very same principles, which lead him to doubt, with

various degrees of uncertainty, where the evidence is less sure. To

conceive, that inquiry must lead to scepticism, is itself a species of

scepticism, as to the power and evidence of the principles to which we

have given our assent, more degrading, because still more irrational,

than that open and consistent scepticism which it dreads. It would,

indeed, be an unworthy homage to truths, which we profess to venerate,

to suppose, that adoration can be paid to them only while we are

ignorant of their nature; and that to approach their altars would be to

discover, that the majestic forms, which seem animated at a distance,

are only lifeless idols, as insensible as the incense which we have

offered to them.

The study of the powers and limits of the understanding, and of the

sources of evidence in external nature and ourselves, instead of either

forming or favouring a tendency to scepticism, is then, it appears,

the surest, or rather the only mode, of removing the danger of such a

tendency. That mind may soon doubt even of the most important truths,

which has never learned to distinguish the doubtful from the true. But

to know well the irresistible evidence on which truth is founded, is to

believe in it, and to believe in it forever.

Nor is it from the danger of scepticism only, that a just view of the

principles of his intellectual constitution tends to preserve the

philosophic inquirer. It saves him, also, from that presumptuous and

haughty dogmatism, which, though free from doubt, is not, therefore,

necessarily free from error; and which is, indeed, much more likely

to be fixed in error than in truth, where the inquiry, that precedes

conviction, has been casual and incomplete. A just view of our nature

as intelligent beings, at the same time that it teaches us enough

of our strength to allow us to rest with confidence on the great

principles, physical, moral, and religious, in which alone it is of

importance for us to confide, teaches us also enough of our weakness,

to render us indulgent to the weakness of others. We cease to be

astonished that multitudes should differ from us; because we know well,

that while nature has made a provision for the universal assent of

mankind to those fundamental physical truths, which are essential to

their very existence, and those _fundamental truths_ of another kind,

which are equally essential to their existence as subjects of moral

government, she has left them, together with principles of improvement

that ensure their intellectual progress, a susceptibility of error,

without which there could be no progression; and while we almost

trace back the circumstances which have modified our own individual

belief, we cannot but be aware, at the same time, how many sources

there are of prejudice, and, consequently, of difference of opinion,

in the various situations in which the multitudes, that differ from

us, have been placed. To feel anger at human error, says an ancient

philosopher, is the same thing as if we were to be angry with those who

stumble in the dark,--with the deaf for not obeying our command,--with

the sick,--with the aged,--with the weary. That very dulness of

discernment, which excites at once our wonder and our wrath, is but a

part of the general frailty of mortality; and the love of our errors

is not less inherent in our constitution than error itself. It is this

general constitution which is to be studied by us, that we may know

with what mistakes and weaknesses we must have to deal, when we have to

deal with our fellow-men; and the true art, therefore, of learning to

forgive _individuals_, is to learn first how much we have to forgive

_to the whole human race_. “Illud potius cogitabis, non esse irascendum

erroribus. Quid enim, si quis irascatur in tenebris parum vestigia

certa ponentibus? Quid si quis surdis, imperia non exaudientibus? Quid

si pueris, quod neglecto dispectu officiorum, ad lusus et ineptos

æqualium jocos spectent? Quid si illis irasci velis, qui ægrotant,

senescunt, fatigantur? Inter cætera mortalitatis incommoda, et hæc

est, caligo mentium: nec tantum necessitas errandi, sed errorum amor.

Ne singulis irascaris, universis ignoscendum: generi humano venia

tribuenda est.”[9]

How much of the fury of the persecuting spirit of darker ages would

have been softened and turned into moderation, by juster views of the

nature of man, and of all the circumstances on which belief depends! It

appears to us so very easy to believe what we consider as true,--or,

rather, it appears to us so impossible to disbelieve it,--that, if we

judge from our own momentary feelings only, without any knowledge of

the general nature of belief, and of all the principles in our mental

constitution by which it is diversified, we very naturally look on

the dissent of others as a sort of wilful and obstinate contrariety,

and almost as an insulting denial of a right of approbation, which we

consider ourselves, in these circumstances, as very justly entitled to

claim. The transition from this supposed culpability to the associated

ideas of pains and penalties, is a very natural one; and there is,

therefore a sufficient fund of persecution in mere ignorance, though

the spirit of it were not, as it usually is, aggravated by degrading

notions of the divine Being, and false impressions of religious duty.

Very different are the sentiments which the science of mind produces

and cherishes. It makes us tolerant, not merely by showing the

absurdity of endeavouring to overcome, by punishment, a belief which

does not depend on suffering; but which may remain, and even gather

additional strength, in imprisonment, in exile, under the axe, and

at the stake. The absurdity of every attempt of this kind it shews

indeed; but it makes us feel, still more intimately, that injustice

of it, which is worse than absurdity,--by shewing our common nature,

in all the principles of truth and error, with those whom we would

oppress; all having faculties that may lead to truth, and tendencies of

various kinds which may mislead to error, and the mere accidental and

temporary difference of power being, if not the greatest, at least the

most obvious circumstance, which, in all ages, has distinguished the

_persecutor_ from the _persecuted_.

Let not this weak, unknowing hand,

Presume thy bolts to throw;

Or deal damnation round the land,

On all I judge thy foe!

If I am right,--thy grace impart,

Still in the right to stay;

If I am wrong,--O, teach my heart,

To find the better way.[10]

Such is the language of devout philosophy. No proud assertion of

individual infallibility,--no triumph over the consequences in others,

of a fallible nature, which ourselves partake in common,--but the

expression of feelings more suited to earthly weakness,--of a modest

joy of belief, which is not less delightful for the humility that

tempers it; and of a modest sorrow for the seeming errors of others, to

which the consciousness of our own nature gives a sympathy of warmer

interest. The more important the subject of difference, the _greater_,

not the _less_, will be the indulgence of him who has learned to trace

the sources of human error,--of error, that has its origin not in

our weakness and imperfection merely, but often in the most virtuous

affections of the heart,--in that respect for age, and admiration of

virtue, and gratitude for kindness received, which make the opinions

of those whom we love and honour seem to us, in our early years, as

little questionable, as the virtues which we love to contemplate, or

the very kindness which we feel at every moment beaming on our heart,

in the tender protection that surrounds us. That the subjects on which

we may differ from others, are _important to happiness_, of course

implies, that it is no slight misfortune _to have erred_; and that the

mere error, therefore, must be already too great an evil to require any

addition from our individual contempt or indignation, far less from the

vengeance of public authority,--that _may_ be right, in the opinions

which it conceives to be insulted by partial dissent; but which _must_

be wrong, in the means which it takes to avenge them. To be sincerely

thankful for truths received, is, by the very nature of the feeling, to

be sensible how great a blessing those have lost who are deprived of

the same enjoyment; and to look down, then, with insolent disdain, on

the unfortunate victim of error, is, indeed to render contemptible, (as

far as it is in our feeble power to render it contemptible,) not the

error which we despise, but the truth which allows us to despise it.

The remarks which I have as yet made, on the effects of acquaintance

with the Philosophy of Mind, relate to its influence on the general

spirit of philosophical inquiry; the advantages which must be derived,

in every science, from a knowledge of the extent of the power of the

intellectual instruments which we use for the discovery of truth; the

skill which we thence acquire in distinguishing the questions in which

we may justly hope to discover truth, from those questions of idle and

endless controversy, the decision of which is altogether beyond the

reach of our faculties; and the consequent moderation in the temper,

with which we look both to our own possible attainments, and to the

errors of others.

But beside these general advantages, which the Philosophy of Mind

extends to all the inquiries of which human genius is capable, there

are some advantages more peculiarly felt in certain departments of

science or art. It is not merely _with_ the mind that we operate;

the subject of our operations is also often the _mind itself_. In

education, in criticism, in poetry, in eloquence, the mind has to act

upon mind, to produce in it either emotions that are _temporary_, or

affections and opinions that are _permanent_. We have to instruct

it,--to convince it,--to persuade it,--to delight it,--to soften it

with pity,--to agitate it with terror or indignation;--and all these

effects, when other circumstances of genius are the same, we shall

surely be able to produce more readily, if we know the natural laws of

thought and emotion; the feelings which are followed by other feelings;

and the thoughts, which, expanding into other thoughts, almost of

themselves produce the very passion, or conviction, which we wish to

excite.

“One considerable advantage,” says Mr Hume, “which results from the

accurate and abstract philosophy, is its subserviency to the easy and

humane; which, without the former, can never attain a sufficient degree

of exactness in its sentiments, precepts, or reasonings. All polite

letters are nothing but pictures of human life in various attitudes

and situations; and inspire us with different sentiments of praise

or blame, admiration or ridicule, according to the qualities of the

object which they set before us. An artist must be better qualified to

succeed in this undertaking; who, besides a delicate taste and quick

apprehension, possesses an accurate knowledge of the internal fabric,

the operations of the understanding, the workings of the passions, and

the various species of sentiment which discriminate vice and virtue.

However painful this inward search or inquiry may appear, it becomes,

in some measure, requisite to those who would describe with success

the obvious and outward appearances of life and manners. The anatomist

presents to the eye the most hideous and disagreeable objects; but his

science is highly useful to the painter in delineating even a Venus

or an Helen. While the latter employs all the richest colours of his

art, and gives his figures the most graceful and engaging airs, he must

still carry his attention to the inward structure of the human body,

the position of the muscles, the fabric of the bones, and the use and

figure of every part or organ. Accuracy is, in every case, advantageous

to beauty, and just reasoning to delicacy of sentiment;--in vain would

we exalt the one by depreciating the other.”[11]

There is a most striking passage to the same purport, in that beautiful

dialogue on ancient oratory, which has been ascribed, without any

very satisfactory evidence, to various authors, particularly to

Quinctilian, the younger Pliny, and Tacitus, and which is not unworthy

of the most eminent of the names to which it has been ascribed. After

dwelling on the universal science and erudition of the great master

of Roman eloquence, the chief speaker in the dialogue proceeds to

show the peculiar advantage which oratory must derive from _moral and

intellectual science_, to the neglect of which fundamental study, as

superseded by the frivolous disputations of the rhetorical schools, he

ascribes the decay of eloquence in the age of which he speaks.

“Ita enim est, optimi viri, ita, ex multa eruditione, ex pluribus

artibus, et omnium rerum scientia, exundat et exuberat illa admirabilis

eloquentia. Neque oratoris vis et facultas, sicut ceterarum rerum,

angustis et brevibus terminis eluditur; sed is est orator, qui de

omni quæstione pulchre, et ornate, et ad persuadendum apte dicere,

pro dignitate rerum ad utilitatem temporum, cum voluptate audientium,

possit. Hæc sibi illi veteres persuadebant. Ad hæc efficienda

intelligebant opus esse, non ut Rhetorum scholis declamarent,--sed

ut his artibus pectus implerent, in quibus de bonis ac malis, de

honesto ac turpi, de justo et injusto disputatur;--de quibus copiose,

et varie, et ornate, nemo dicere potest, nisi qui cognovit naturam

humanam.--Ex his fontibus etiam illa profluunt, ut facilius iram

judicis vel instiget, vel leniat, qui scit quid ira, promptius ad

miserationem impellat qui scit quid sit misericordia, et quibus animi

motibus concitetur. In his artibus exercitationibusque versatus orator,

sive apud infestos, sive apud cupidos, sive apud invidentes, sive

apud tristes, sive apud timentes dicendum habuerit, tenebit habenas

animorum, et prout cujusque natura postulabit, adhibebit manum et

temperabit orationem, parato omni instrumento, et ad usum reposito.”[12]

What is the whole art of criticism, in its most important

applications, but the knowledge of the most natural successions of

thought and feeling in the mind? We judge of the perspicuity and order

of a discourse, by knowing the progress in which the mind, by the

developement of truth after truth, may be made at last to see the full

meaning of the most complex proposition. We judge of the beauty of

impassioned poetry or eloquence, by knowing whether the figures, the

images, the very feelings described, be such as, from our observation

of the laws that regulate the internal series of changes in the mind,

we know to be consistent with that state of emotion, in which a mind

must exist that has been placed in the situation supposed. If all other

circumstances be equal, he will undoubtedly be the best critic, who

knows best the phenomena of human thought and feeling; and, without

this knowledge, criticism can be nothing but a measurement of words,

or a repetition of the ever repeated and endless common places of

rhetoric. The knowledge of _nature_,--of the necessity of which critics

speak so much, and so justly, and which is as essential to the critic

himself, as to the writer on whom he sits in judgment,--is only another

name for the knowledge of the successive transitions of feeling of

the mind, in all the innumerable diversities in which it is capable

of being modified, by the variety of circumstances in which it maybe

placed. It is for this reason, that, with so great an abundance of

the mere art, or rather of the mere technical phrases of criticism,

we have so very little of the _science_ of it; because the science

of criticism implies an acquaintance with the philosophy of thought

and passion, which few can be expected to possess; and though nothing

can be easier than to deliver opinions, such as pass current in the

drawing-room, and even in the literary circle, which the frivolous may

admire as profound, and the ignorant as erudite, and which many voices

may be proud to repeat; though even the dull and pedantic are as able

as the wise to say, in fluent language, that one passage of a work of

genius is beautiful, and another the reverse,--because one of them is

in accordance with some technical rules, or because Homer and Milton

have passages similar to the one, and not to the other: it is far from

being equally easy to show, how the one passage is beautiful, from its

truth of character, and the other, though perhaps rich in harmony of

rhythm and rhetorical ornament, is yet faulty, by its violation of the

more important harmony of thought and emotion,--a harmony which nature

observes as faithfully, in the progress of those vehement passions

that appear most wild and irregular, as in the calmest successions of

feeling of the most tranquil hours. It would indeed, be too much to

say, as in the well known couplet of Pope,

“Let such teach others who themselves excel,

And censure freely, who have written well;”[13]

for the critic requires only _one_ of the two great talents, which in

the poet, ought to exist together, but which may yet exist separately.

In the poet, there must be, in the first place, an inventive fancy

to bring together thoughts and images which have never been combined

before; and with this inventive fancy, a discriminating judgment, which

is to measure, by the standard of nature, the products of invention;

and to retain them, only if they appear such, as though perhaps never

before combined, might yet, in conformity with the natural laws of

thought, have occurred to a mind, in the circumstances represented, as

truly, as the other thoughts or images, which the works of other poets

have rendered more familiar. This latter talent,--the judgment which

determines the intrinsic beauty and fidelity to general nature,--is all

which is absolutely requisite to the _critic_, who is not, therefore,

under the necessity of being himself “the great sublime” which he

draws. Yet, though all the elements of excellence in the artist are not

absolutely requisite for the judgment of the sage and discriminating

admirer of the noble works which that excellence may have produced,

some of these elements unquestionably are requisite,--elements, for

which the critic may search in vain in all the rules of rhetoricians,

and even in the perusal of all the masterpieces of ancient and modern

times, unless, to an acquaintance with these, he add an accurate

acquaintance with that _intellectual and moral nature of man_, the

beautiful conformity to which was the essential charm of all the

pathos, and all the eloquence, which he has admired.
