I desire you not to imagine neither that I understand by the first

philosophy even such a science as my Lord Bacon describes—a science of

general observations and axioms, such as do not belong properly to any

particular part of science, but are common to many, “and of an higher

stage,” as he expresses himself. He complains that philosophers have not

gone up to the “spring-head,” which would be of “general and excellent

use for the disclosing of Nature and the abridgment of art,” though they

“draw now and then a bucket of water out of the well for some particular

use.” I respect—no man more—this great authority; but I respect no

authority enough to subscribe on the faith of it, to that which appears

to me fantastical, as if it were real. Now this spring-head of science

is purely fantastical, and the figure conveys a false notion to the mind,

as figures employed licentiously are apt to do. The great author himself

calls these axioms, which are to constitute his first philosophy,

observations. Such they are properly; for there are some uniform

principles, or uniform impressions of the same nature, to be observed in

very different subjects, “una eademque naturæ vestigia aut signacula

diversis materiis et subjectis impressa.” These observations, therefore,

when they are sufficiently verified and well established, may be properly

applied in discourse, or writing, from one subject to another. But I

apprehend that when they are so applied, they serve rather to illustrate

a proposition than to disclose Nature, or to abridge art. They may have

a better foundation than similitudes and comparisons more loosely and

more superficially made. They may compare realities, not appearances;

things that Nature has made alike, not things that seem only to have some

relation of this kind in our imaginations. But still they are

comparisons of things distinct and independent. They do not lead us to

things, but things that are lead us to make them. He who possesses two

sciences, and the same will be often true of arts, may find in certain

respects a similitude between them because he possesses both. If he did

not possess both, he would be led by neither to the acquisition of the

other. Such observations are effects, not means of knowledge; and,

therefore, to suppose that any collection of them can constitute a

science of an “higher stage,” from whence we may reason _à priori_ down

to particulars, is, I presume, to suppose something very groundless, and

very useless at best, to the advancement of knowledge. A pretended

science of this kind must be barren of knowledge, and may be fruitful of

error, as the Persian magic was, if it proceeded on the faint analogy

that may be discovered between physics and politics, and deduced the

rules of civil government from what the professors of it observed of the

operations and works of Nature in the material world. The very specimen

of their magic which my Lord Bacon has given would be sufficient to

justify what is here objected to his doctrine.

Let us conclude this head by mentioning two examples among others which

he brings to explain the better what he means by his first philosophy.

The first is this axiom, “If to unequals you add equals, all will be

unequal.” This, he says, is an axiom of justice as well as of

mathematics; and he asks whether there is not a true coincidence between

commutative and distributive justice, and arithmetical and geometrical

proportion. But I would ask in my turn whether the certainty that any

arithmetician or geometrician has of the arithmetical or geometrical

truth will lead him to discover this coincidence. I ask whether the most

profound lawyer who never heard perhaps this axiom would be led to it by

his notions of commutative and distributive justice. Certainly not. He

who is well skilled in arithmetic or geometry, and in jurisprudence, may

observe perhaps this uniformity of natural principle or impression

because he is so skilled, though, to say the truth, it be not very

obvious; but he will not have derived his knowledge of it from any

spring-head of a first philosophy, from any science of an “higher stage”

than arithmetic, geometry, and jurisprudence.

The second example is this axiom, “That the destruction of things is

prevented by the reduction of them to their first principles.” This rule

is said to hold in religion, in physics, and in politics; and Machiavel

is quoted for having established it in the last of these. Now though

this axiom be generally, it is not universally, true; and, to say nothing

of physics, it will not be hard to produce, in contradiction to it,

examples of religious and civil institutions that would have perished if

they had been kept strictly to their first principles, and that have been

supported by departing more or less from them. It may seem justly matter

of wonder that the author of the “Advancement of Learning” should espouse

this maxim in religion and politics, as well as physics, so absolutely,

and that he should place it as an axiom of his first philosophy

relatively to the three, since he could not do it without falling into

the abuse he condemns so much in his “Organum Novum”—the abuse

philosophers are guilty of when they suffer the mind to rise too fast, as

it is apt to do, from particulars to remote and general axioms. That the

author of the “Political Discourses” should fall into this abuse is not

at all strange. The same abuse runs through all his writings, in which,

among many wise and many wicked reflections and precepts, he establishes

frequently general maxims or rules of conduct on a few particular

examples, and sometimes on a single example. Upon the whole matter, one

of these axioms communicates no knowledge but that which we must have

before we can know the axiom, and the other may betray us into great

error when we apply it to use and action. One is unprofitable, the other

dangerous; and the philosophy which admits them as principles of general

knowledge deserves ill to be reputed philosophy. It would have been just

as useful, and much more safe, to admit into this receptacle of axioms

those self-evident and necessary truths alone of which we have an

immediate perception, since they are not confined to any special parts of

science, but are common to several, or to all. Thus these profitable

axioms, “What is, is,” “The whole is bigger than a part,” and divers

others, might serve to enlarge the spring-head of a first philosophy, and

be of excellent use in arguing _ex prœcognitis et prœconcessis_.

If you ask me now what I understand then by a first philosophy, my answer

will be such as I suppose you already prepared to receive. I understand

by a first philosophy, that which deserves the first place on account of

the dignity and importance of its objects, natural theology or theism,

and natural religion or ethics. If we consider the order of the sciences

in their rise and progress, the first place belongs to natural

philosophy, the mother of them all, or the trunk, the tree of knowledge,

out of which, and in proportion to which, like so many branches, they all

grow. These branches spread wide, and bear even fruits of different

kinds. But the sap that made them shoot, and makes them flourish, rises

from the root through the trunk, and their productions are varied

according to the variety of strainers through which it flows. In plain

terms, I speak not here of supernatural, or revealed science; and

therefore I say that all science, if it be real, must rise from below,

and from our own level. It cannot descend from above, nor from superior

systems of being and knowledge. Truth of existence is truth of

knowledge, and therefore reason searches after them in one of these

scenes, where both are to be found together, and are within our reach;

whilst imagination hopes fondly to find them in another, where both of

them are to be found, but surely not by us. The notices we receive from

without concerning the beings that surround us, and the inward

consciousness we have of our own, are the foundations, and the true

criterions too, of all the knowledge we acquire of body and of mind: and

body and mind are objects alike of natural philosophy. We assume

commonly that they are two distinct substances. Be it so. They are

still united, and blended, as it were, together, in one human nature: and

all natures, united or not, fall within the province of natural

philosophy. On the hypothesis indeed that body and soul are two distinct

substances, one of which subsists after the dissolution of the other,

certain men, who have taken the whimsical title of metaphysicians, as if

they had science beyond the bounds of Nature, or of Nature discoverable

by others, have taken likewise to themselves the doctrine of mind; and

have left that of body, under the name of physics, to a supposed inferior

order of philosophers. But the right of these stands good; for all the

knowledge that can be acquired about mind, or the unextended substance of

the Cartesians, must be acquired, like that about body, or the extended

substance, within the bounds of their province, and by the means they

employ, particular experiments and observations. Nothing can be true of

mind, any more than of body, that is repugnant to these; and an

intellectual hypothesis which is not supported by the intellectual

phenomena is at least as ridiculous as a corporeal hypothesis which is

not supported by the corporeal phenomena.

If I have said thus much in this place concerning natural philosophy, it

has not been without good reason. I consider theology and ethics as the

first of sciences in pre-eminence of rank. But I consider the constant

contemplation of Nature—by which I mean the whole system of God’s works

as far as it lies open to us—as the common spring of all sciences, and

even of these. What has been said agreeably to this notion seems to me

evidently true; and yet metaphysical divines and philosophers proceed in

direct contradiction to it, and have thereby, if I mistake not,

bewildered themselves, and a great part of mankind, in such inextricable

labyrinths of hypothetical reasoning, that few men can find their way

back, and none can find it forward into the road of truth. To dwell

long, and on some points always, in particular knowledge, tires the

patience of these impetuous philosophers. They fly to generals. To

consider attentively even the minutest phenomena of body and mind

mortifies their pride. Rather than creep up slowly, _à posteriori_, to a

little general knowledge, they soar at once as far and as high as

imagination can carry them. From thence they descend again, armed with

systems and arguments _à priori_; and, regardless how these agree or

clash with the phenomena of Nature, they impose them on mankind.

It is this manner of philosophising, this preposterous method of

beginning our search after truth out of the bounds of human knowledge, or

of continuing it beyond them, that has corrupted natural theology and

natural religion in all ages. They have been corrupted to such a degree

that it is grown, and was so long since, as necessary to plead the cause

of God, if I may use this expression after Seneca, against the divine as

against the atheist; to assert his existence against the latter, to

defend his attributes against the former, and to justify his providence

against both. To both a sincere and humble theist might say very

properly, “I make no difference between you on many occasions, because it

is indifferent whether you deny or defame the Supreme Being.” Nay,

Plutarch, though little orthodox in theology, was not in the wrong

perhaps when he declared the last to be the worst.

In treating the subjects about which I shall write to you in these

letters or essays, it will be therefore necessary to distinguish genuine

and pure theism from the unnatural and profane mixtures of human

imagination—what we can know of God from what we cannot know. This is

the more necessary, too, because, whilst true and false notions about God

and religion are blended together in our minds under one specious name of

science, the false are more likely to make men doubt of the true, as it

often happens, than to persuade men that they are true themselves. Now,

in order to this purpose, nothing can be more effectual than to go to the

root of error, of that primitive error which encourages our curiosity,

sustains our pride, fortifies our prejudices, and gives pretence to

delusion. This primitive error consists in the high opinion we are apt

to entertain of the human mind, though it holds, in truth, a very low

rank in the intellectual system. To cure this error we need only turn

our eyes inward, and contemplate impartially what passes there from the

infancy to the maturity of the mind. Thus it will not be difficult, and

thus alone it is possible, to discover the true nature of human

knowledge—how far it extends, how far it is real, and where and how it

begins to be fantastical.

Such an inquiry, if it cannot check the presumption nor humble the pride

of metaphysicians, may serve to undeceive others. Locke pursued it; he

grounded all he taught on the phenomena of Nature; he appealed to the

experience and conscious knowledge of every one, and rendered all he

advanced intelligible. Leibnitz, one of the vainest and most chimerical

men that ever got a name in philosophy, and who is often so

unintelligible that no man ought to believe he understood himself,

censured Locke as a superficial philosopher. What has happened? The

philosophy of one has forced its way into general approbation, that of

the other has carried no conviction and scarce any information to those

who have misspent their time about it. To speak the truth, though it may

seem a paradox, our knowledge on many subjects, and particularly on those

which we intend here, must be superficial to be real. This is the

condition of humanity. We are placed, as it were, in an intellectual

twilight, where we discover but few things clearly, and none entirely,

and yet see just enough to tempt us with the hope of making better and

more discoveries. Thus flattered, men push their inquiries on, and may

be properly enough compared to Ixion, who “imagined he had Juno in his

arms whilst he embraced a cloud.”

To be contented to know things as God has made us capable of knowing them

is, then, a first principle necessary to secure us from falling into

error; and if there is any subject upon which we should be most on our

guard against error, it is surely that which I have called here the first

philosophy. God is hid from us in the majesty of His nature, and the

little we discover of Him must be discovered by the light that is

reflected from His works. Out of this light, therefore, we should never

go in our inquiries and reasonings about His nature, His attributes, and

the order of His providence; and yet upon these subjects men depart the

furthest from it—nay, they who depart the furthest are the best heard by

the bulk of mankind. The less men know, the more they believe that they

know. Belief passes in their minds for knowledge, and the very

circumstances which should beget doubt produce increase of faith. Every

glittering apparition that is pointed out to them in the vast wild of

imagination passes for a reality; and the more distant, the more

confused, the more incomprehensible it is, the more sublime it is

esteemed. He who should attempt to shift these scenes of airy vision for

those of real knowledge might expect to be treated with scorn and anger

by the whole theological and metaphysical tribe, the masters and the

scholars; he would be despised as a plebeian philosopher, and railed at

as an infidel. It would be sounded high that he debased human nature,

which has a “cognation,” so the reverend and learned Doctor Cudworth

calls it, with the divine; that the soul of man, immaterial and immortal

by its nature, was made to contemplate higher and nobler objects than

this sensible world, and even than itself, since it was made to

contemplate God and to be united to Him. In such clamour as this the

voice of truth and of reason would be drowned, and, with both of them on

his side, he who opposed it would make many enemies and few converts—nay,

I am apt to think that some of these, if he made any, would say to him,

as soon as the gaudy visions of error were dispelled, and till they were

accustomed to the simplicity of truth, “Pol me occidistis.” Prudence

forbids me, therefore, to write as I think to the world, whilst

friendship forbids me to write otherwise to you. I have been a martyr of

faction in politics, and have no vocation to be so in philosophy.

But there is another consideration which deserves more regard, because it

is of a public nature, and because the common interests of society may be

affected by it. Truth and falsehood, knowledge and ignorance,

revelations of the Creator, inventions of the creature, dictates of

reason, sallies of enthusiasm, have been blended so long together in our

systems of theology that it may be thought dangerous to separate them,

lest by attacking some parts of these systems we should shake the whole.

It may be thought that error itself deserves to be respected on this

account, and that men who are deluded for their good should be deluded

on.

Some such reflections as these it is probable that Erasmus made when he

observed, in one of his letters to Melancthon, that Plato, dreaming of a

philosophical commonwealth, saw the impossibility of governing the

multitude without deceiving them. “Let not Christians lie,” says this

great divine: “but let it not be thought neither that every truth ought

to be thrown out to the vulgar.” (“Non expedit omnem veritatem prodere

vulgo.”) Scævola and Varro were more explicit than Erasmus, and more

reasonable than Plato. They held not only that many truths were to be

concealed from the vulgar, but that it was expedient the vulgar should

believe many things that were false. They distinguished at the same

time, very rightly, between the regard due to religions already

established, and the conduct to be held in the establishment of them.

The Greek assumed that men could not be governed by truth, and erected on

this principle a fabulous theology. The Romans were not of the same

opinion. Varro declared expressly that if he had been to frame a new

institution, he would have framed it “ex naturæ potius formula.” But

they both thought that things evidently false might deserve an outward

respect when they are interwoven into a system of government. This

outward respect every good citizen will show them in such a case, and

they can claim no more in any. He will not propagate these errors, but

he will be cautious how he propagates even truth in opposition to them.

There has been much noise made about free-thinking; and men have been

animated in the contest by a spirit that becomes neither the character of

divines nor that of good citizens, by an arbitrary tyrannical spirit

under the mask of religious zeal, and by a presumptuous factious spirit

under that of liberty. If the first could prevail, they would establish

implicit belief and blind obedience, and an Inquisition to maintain this

abject servitude. To assert antipodes might become once more as

heretical as Arianism or Pelagianism; and men might be dragged to the

jails of some Holy Office, like Galilei, for saying they had seen what in

fact they had seen, and what every one else that pleased might see. If

the second could prevail, they would destroy at once the general

influence of religion by shaking the foundations of it which education

had laid. These are wide extremes. Is there no middle path in which a

reasonable man and a good citizen may direct his steps? I think there

is.

Every one has an undoubted right to think freely—nay, it is the duty of

every one to do so as far as he has the necessary means and

opportunities. This duty, too, is in no case so incumbent on him as in

those that regard what I call the first philosophy. They who have

neither means nor opportunities of this sort must submit their opinions

to authority; and to what authority can they resign themselves so

properly and so safely as to that of the laws and constitution of their

country? In general, nothing can be more absurd than to take opinions of

the greatest moment, and such as concern us the most intimately, on

trust; but there is no help against it in many particular cases. Things

the most absurd in speculation become necessary in practice. Such is the

human constitution, and reason excuses them on the account of this

necessity. Reason does even a little more, and it is all she can do.

She gives the best direction possible to the absurdity. Thus she directs

those who must believe because they cannot know, to believe in the laws

of their country, and conform their opinions and practice to those of

their ancestors, to those of Coruncanius, of Scipio, of Scævola—not to

those of Zeno, of Cleanthes, of Chrysippus.

But now the same reason that gives this direction to such men as these

will give a very contrary direction to those who have the means and

opportunities the others want. Far from advising them to submit to this

mental bondage, she will advise them to employ their whole industry to

exert the utmost freedom of thought, and to rest on no authority but

hers—that is, their own. She will speak to them in the language of the

Soufys, a sect of philosophers in Persia that travellers have mentioned.

“Doubt,” say these wise and honest freethinkers, “is the key of

knowledge. He who never doubts, never examines. He who never examines,

discovers nothing. He who discovers nothing, is blind and will remain

so. If you find no reason to doubt concerning the opinions of your

fathers, keep to them; they will be sufficient for you. If you find any

reason to doubt concerning them, seek the truth quietly, but take care

not to disturb the minds of other men.”

Let us proceed agreeably to these maxims. Let us seek truth, but seek it

quietly as well as freely. Let us not imagine, like some who are called

freethinkers, that every man, who can think and judge for himself, as he

has a right to do, has therefore a right of speaking, any more than of

acting, according to the full freedom of his thoughts. The freedom

belongs to him as a rational creature; he lies under the restraint as a

member of society.

If the religion we profess contained nothing more than articles of faith

and points of doctrine clearly revealed to us in the Gospel, we might be

obliged to renounce our natural freedom of thought in favour of this

supernatural authority. But since it is notorious that a certain order

of men, who call themselves the Church, have been employed to make and

propagate a theological system of their own, which they call

Christianity, from the days of the Apostles, and even from these days

inclusively, it is our duty to examine and analyse the whole, that we may

distinguish what is divine from what is human; adhere to the first

implicitly, and ascribe to the last no more authority than the word of

man deserves.

Such an examination is the more necessary to be undertaken by every one

who is concerned for the truth of his religion and for the honour of

Christianity, because the first preachers of it were not, and they who

preach it still are not, agreed about many of the most important points

of their system; because the controversies raised by these men have

banished union, peace, and charity out of the Christian world; and

because some parts of the system savour so much of superstition and

enthusiasm that all the prejudices of education and the whole weight of

civil and ecclesiastical power can hardly keep them in credit. These

considerations deserve the more attention because nothing can be more

true than what Plutarch said of old, and my Lord Bacon has said since:

one, that superstition, and the other, that vain controversies are

principal causes of atheism.

I neither expect nor desire to see any public revision made of the

present system of Christianity. I should fear an attempt to alter the

established religion as much as they who have the most bigot attachment

to it, and for reasons as good as theirs, though not entirely the same.

I speak only of the duty of every private man to examine for himself,

which would have an immediate good effect relatively to himself, and

might have in time a good effect relatively to the public, since it would

dispose the minds of men to a greater indifference about theological

disputes, which are the disgrace of Christianity and have been the

plagues of the world.
