CHAPTER XVIII.

OF FAITH AND REASON, AND THEIR DISTINCT PROVINCES.

1. Necessary to know their boundaries.

It has been above shown, 1. That we are of necessity ignorant, and want

knowledge of all sorts, where we want ideas. 2. That we are ignorant,

and want rational knowledge, where we want proofs. 3. That we want

certain knowledge and certainty, as far as we want clear and determined

specific ideas. 4. That we want probability to direct our assent in

matters where we have neither knowledge of our own nor testimony of

other men to bottom our reason upon. From these things thus premised, I

think we may come to lay down THE MEASURES AND BOUNDARIES BETWEEN FAITH

AND REASON: the want whereof may possibly have been the cause, if not of

great disorders, yet at least of great disputes, and perhaps mistakes

in the world. For till it be resolved how far we are to be guided by

reason, and how far by faith, we shall in vain dispute, and endeavour to

convince one another in matters of religion.

2. Faith and Reason, what, as contradistingushed.

I find every sect, as far as reason will help them, make use of it

gladly: and where it fails them, they cry out, It is matter of faith,

and above reason. And I do not see how they can argue with any one,

or ever convince a gainsayer who makes use of the same plea, without

setting down strict boundaries between faith and reason; which ought to

be the first point established in all questions where faith has anything

to do.

REASON, therefore, here, as contradistinguished to FAITH, I take to be

the discovery of the certainty or probability of such propositions or

truths, which the mind arrives at by deduction made from such ideas,

which it has got by the use of its natural faculties; viz. by sensation

or reflection.

FAITH, on the other side, is the assent to any proposition, not thus

made out by the deductions of reason, but upon the credit of

the proposer, as coming from God, in some extraordinary way of

communication. This way of discovering truths to men, we call

REVELATION.

3. First, No new simple Idea can be conveyed by traditional Revelation.

FIRST, Then I say, that NO MAN INSPIRED BY GOD CAN BY ANY REVELATION

COMMUNICATE TO OTHERS ANY NEW SIMPLE IDEAS WHICH THEY HAD NOT BEFORE

FROM SENSATION OR REFLECTION. For, whatsoever impressions he himself may

have from the immediate hand of God, this revelation, if it be of new

simple ideas, cannot be conveyed to another, either by words or any

other signs. Because words, by their immediate operation on us, cause no

other ideas but of their natural sounds: and it is by the custom of

using them for signs, that they excite and revive in our minds latent

ideas; but yet only such ideas as were there before. For words, seen or

heard, recal to our thoughts those ideas only which to us they have been

wont to be signs of, but cannot introduce any perfectly new, and

formerly unknown simple ideas. The same holds in all other signs; which

cannot signify to us things of which we have before never had any idea

at all.

Thus whatever things were discovered to St. Paul, when he was rapt up

into the third heaven; whatever new ideas his mind there received, all

the description he can make to others of that place, is only this, That

there are such things, 'as eye hath not seen, nor ear heard, nor hath

it entered into the heart of man to conceive.' And supposing God should

discover to any one, supernaturally, a species of creatures inhabiting,

for example, Jupiter or Saturn, (for that it is possible there may be

such, nobody can deny,) which had six senses; and imprint on his mind

the ideas conveyed to theirs by that sixth sense: he could no more, by

words, produce in the minds of other men those ideas imprinted by that

sixth sense, than one of us could convey the idea of any colour, by the

sound of words, into a man who, having the other four senses perfect,

had always totally wanted the fifth, of seeing. For our simple ideas,

then, which are the foundation, and sole matter of all our notions and

knowledge, we must depend wholly on our reason, I mean our natural

faculties; and can by no means receive them, or any of them, from

traditional revelation. I say, TRADITIONAL REVELATION, in distinction to

ORIGINAL REVELATION. By the one, I mean that first impression which is

made immediately by God on the mind of any man, to which we cannot set

any bounds; and by the other, those impressions delivered over to others

in words, and the ordinary ways of conveying our conceptions one to

another.

4. Secondly, Traditional Revelation may make us know Propositions

knowable also by Reason, but not with the same Certainty that Reason

doth.

SECONDLY, I say that THE SAME TRUTHS MAY BE DISCOVERED, AND CONVEYED

DOWN FROM REVELATION, WHICH ARE DISCERNABLE TO US BY REASON, AND BY

THOSE IDEAS WE NATURALLY MAY HAVE. So God might, by revelation, discover

the truth of any proposition in Euclid; as well as men, by the natural

use of their faculties, come to make the discovery themselves. In all

things of this kind there is little need or use of revelation, God

having furnished us with natural and surer means to arrive at the

knowledge of them. For whatsoever truth we come to the clear discovery

of, from the knowledge and contemplation of our own ideas, will always

be certainer to us than those which are conveyed to us by TRADITIONAL

REVELATION. For the knowledge we have that this revelation came at first

from God, can never be so sure as the knowledge we have from the clear

and distinct perception of the agreement or disagreement of our own

ideas: v.g. if it were revealed some ages since, that the three angles

of a triangle were equal to two right ones, I might assent to the truth

of that proposition, upon the credit of the tradition, that it was

revealed: but that would never amount to so great a certainty as the

knowledge of it, upon the comparing and measuring my own ideas of two

right angles, and the three angles of a triangle. The like holds in

matter of fact knowable by our senses; v.g. the history of the deluge is

conveyed to us by writings which had their original from revelation: and

yet nobody, I think, will say he has as certain and clear a knowledge of

the flood as Noah, that saw it; or that he himself would have had, had

he then been alive and seen it. For he has no greater an assurance than

that of his senses, that it is writ in the book supposed writ by Moses

inspired: but he has not so great an assurance that Moses wrote that

book as if he had seen Moses write it. So that the assurance of its

being a revelation is less still than the assurance of his senses.

5. Even Original Revelation cannot be admitted against the clear Evidence

of Reason.

In propositions, then, whose certainty is built upon the clear

perception of the agreement or disagreement of our ideas, attained

either by immediate intuition, as in self-evident propositions, or

by evident deductions of reason in demonstrations we need not the

assistance of revelation, as necessary to gain our assent, and introduce

them into our minds. Because the natural ways of knowledge could settle

them there, or had done it already; which is the greatest assurance we

can possibly have of anything, unless where God immediately reveals it

to us: and there too our assurance can be no greater than our knowledge

is, that it IS a revelation from God. But yet nothing, I think, can,

under that title, shake or overrule plain knowledge; or rationally

prevail with any man to admit it for true, in a direct contradiction to

the clear evidence of his own understanding. For, since no evidence of

our faculties, by which we receive such revelations, can exceed, if

equal, the certainty of our intuitive knowledge, we can never receive

for a truth anything that is directly contrary to our clear and distinct

knowledge; v.g. the ideas of one body and one place do so clearly agree,

and the mind has so evident a perception of their agreement, that we can

never assent to a proposition that affirms the same body to be in two

distant places at once, however it should pretend to the authority of

a divine revelation: since the evidence, first, that we deceive not

ourselves, in ascribing it to God; secondly, that we understand it

right; can never be so great as the evidence of our own intuitive

knowledge, whereby we discern it impossible for the same body to be in

two places at once. And therefore NO PROPOSITION CAN BE RECEIVED FOR

DIVINE REVELATION, OR OBTAIN THE ASSENT DUE TO ALL SUCH, IF IT BE

CONTRADICTORY TO OUR CLEAR INTUITIVE KNOWLEDGE. Because this would be to

subvert the principles and foundations of all knowledge, evidence, and

assent whatsoever: and there would be left no difference between truth

and falsehood, no measures of credible and incredible in the world, if

doubtful propositions shall take place before self-evident; and what

we certainly know give way to what we may possibly be mistaken in. In

propositions therefore contrary to the clear perception of the agreement

or disagreement of any of our ideas, it will be in vain to urge them as

matters of faith. They cannot move our assent under that or any other

title whatsoever. For faith can never convince us of anything that

contradicts our knowledge. Because, though faith be founded on the

testimony of God (who cannot lie) revealing any proposition to us:

yet we cannot have an assurance of the truth of its being a divine

revelation greater than our own knowledge. Since the whole strength of

the certainty depends upon our knowledge that God revealed it; which,

in this case, where the proposition supposed revealed contradicts our

knowledge or reason, will always have this objection hanging to it, viz.

that we cannot tell how to conceive that to come from God, the bountiful

Author of our being, which, if received for true, must overturn all the

principles and foundations of knowledge he has given us; render all

our faculties useless; wholly destroy the most excellent part of his

workmanship, our understandings; and put a man in a condition wherein he

will have less light, less conduct than the beast that perisheth. For

if the mind of man can never have a clearer (and perhaps not so clear)

evidence of anything to be a divine revelation, as it has of the

principles of its own reason, it can never have a ground to quit the

clear evidence of its reason, to give a place to a proposition, whose

revelation has not a greater evidence than those principles have.

6. Traditional Revelation much less.

Thus far a man has use of reason, and ought to hearken to it, even in

immediate and original revelation, where it is supposed to be made to

himself. But to all those who pretend not to immediate revelation, but

are required to pay obedience, and to receive the truths revealed to

others, which, by the tradition of writings, or word of mouth, are

conveyed down to them, reason has a great deal more to do, and is that

only which can induce us to receive them. For matter of faith being only

divine revelation, and nothing else, faith, as we use the word, (called

commonly DIVINE FAITH), has to do with no propositions, but those which

are supposed to be divinely revealed. So that I do not see how those who

make revelation alone the sole object of faith can say, That it is a

matter of faith, and not of reason, to believe that such or such

a proposition, to be found in such or such a book, is of divine

inspiration; unless it be revealed that that proposition, or all in that

book, was communicated by divine inspiration. Without such a revelation,

the believing, or not believing, that proposition, or book, to be of

divine authority, can never be matter of faith, but matter of reason;

and such as I must come to an assent to only by the use of my reason,

which can never require or enable me to believe that which is contrary

to itself: it being impossible for reason ever to procure any assent to

that which to itself appears unreasonable.

In all things, therefore, where we have clear evidence from our ideas,

and those principles of knowledge I have above mentioned, reason is the

proper judge; and revelation, though it may, in consenting with it,

confirm its dictates, yet cannot in such cases invalidate its decrees:

nor can we be obliged, where we have the clear and evident sentence of

reason, to quit it for the contrary opinion, under a pretence that it is

matter of faith: which can have no authority against the plain and clear

dictates of reason.

7. Thirdly, things above Reason are, when revealed, the proper matter of

faith.

But, THIRDLY, There being many things wherein we have very imperfect

notions, or none at all; and other things, of whose past, present, or

future existence, by the natural use of our faculties, we can have no

knowledge at all; these, as being beyond the discovery of our natural

faculties, and ABOVE REASON, are, when revealed, THE PROPER MATTER OF

FAITH. Thus, that part of the angels rebelled against God, and thereby

lost their first happy state: and that the dead shall rise, and live

again: these and the like, being beyond the discovery of reason, are

purely matters of faith, with which reason has directly nothing to do.

8. Or not contrary to Reason, if revealed, are Matter of Faith; and must

carry it against probable conjectures of Reason.

But since God, in giving us the light of reason, has not thereby tied

up his own hands from affording us, when he thinks fit, the light of

revelation in any of those matters wherein our natural faculties are

able to give a probable determination; REVELATION, where God has been

pleased to give it, MUST CARRY IT AGAINST THE PROBABLE CONJECTURES OF

REASON. Because the mind not being certain of the truth of that it does

not evidently know, but only yielding to the probability that appears

in it, is bound to give up its assent to such a testimony which, it is

satisfied, comes from one who cannot err, and will not deceive. But

yet, it still belongs to reason to judge of the truth of its being

a revelation, and of the signification of the words wherein it is

delivered. Indeed, if anything shall be thought revelation which is

contrary to the plain principles of reason, and the evident knowledge

the mind has of its own clear and distinct ideas; there reason must be

hearkened to, as to a matter within its province. Since a man can never

have so certain a knowledge, that a proposition which contradicts

the clear principles and evidence of his own knowledge was divinely

revealed, or that he understands the words rightly wherein it is

delivered, as he has that the contrary is true, and so is bound to

consider and judge of it as a matter of reason, and not swallow it,

without examination, as a matter of faith.

9. Revelation in Matters where Reason cannot judge, or but probably,

ought to be hearkened to.

First, Whatever proposition is revealed, of whose truth our mind, by its

natural faculties and notions, cannot judge, that is purely matter of

faith, and above reason.

Secondly, All propositions whereof the mind, by the use of its natural

faculties, can come to determine and judge, from naturally acquired

ideas, are matter of reason; with this difference still, that, in those

concerning which it has but an uncertain evidence, and so is persuaded

of their truth only upon probable grounds, which still admit a

possibility of the contrary to be true, without doing violence to the

certain evidence of its own knowledge, and overturning the principles of

all reason; in such probable propositions, I say, an evident revelation

ought to determine our assent, even against probability. For where the

principles of reason have not evidenced a proposition to be certainly

true or false, there clear revelation, as another principle of truth and

ground of assent, may determine; and so it may be matter of faith, and

be also above reason. Because reason, in that particular matter, being

able to reach no higher than probability, faith gave the determination

where reason came short; and revelation discovered on which side the

truth lay.

10. In Matters where Reason can afford certain Knowledge, that is to be

hearkened to.

Thus far the dominion of faith reaches, and that without any violence or

hindrance to reason; which is not injured or disturbed, but assisted and

improved by new discoveries of truth, coming from the eternal fountain

of all knowledge. Whatever God hath revealed is certainly true: no doubt

can be made of it. This is the proper object of faith: but whether it be

a DIVINE revelation or no, reason must judge; which can never permit the

mind to reject a greater evidence to embrace what is less evident,

nor allow it to entertain probability in opposition to knowledge and

certainty. There can be no evidence that any traditional revelation is

of divine original, in the words we receive it, and in the sense we

understand it, so clear and so certain as that of the principles of

reason: and therefore NOTHING THAT IS CONTRARY TO, AND INCONSISTENT

WITH, THE CLEAR AND SELF-EVIDENT DICTATES OF REASON, HAS A RIGHT TO BE

URGED OR ASSENTED TO AS A MATTER OF FAITH, WHEREIN REASON HATH NOTHING

TO DO. Whatsoever is divine revelation, ought to overrule all our

opinions, prejudices, and interest, and hath a right to be received with

full assent. Such a submission as this, of our reason to faith, takes

not away the landmarks of knowledge: this shakes not the foundations

of reason, but leaves us that use of our faculties for which they were

given us.

11. If the Boundaries be not set between Faith and Reason, no Enthusiasm

or Extravagancy in Religion can be contradicted.

If the provinces of faith and reason are not kept distinct by these

boundaries, there will, in matters of religion, be no room for reason at

all; and those extravagant opinions and ceremonies that are to be found

in the several religions of the world will not deserve to be blamed.

For, to this crying up of faith in OPPOSITION to reason, we may, I

think, in good measure ascribe those absurdities that fill almost all

the religions which possess and divide mankind. For men having been

principled with an opinion, that they must not consult reason in the

things of religion, however apparently contradictory to common sense and

the very principles of all their knowledge, have let loose their fancies

and natural superstition; and have been by them led into so strange

opinions, and extravagant practices in religion, that a considerate man

cannot but stand amazed, at their follies, and judge them so far from

being acceptable to the great and wise God, that he cannot avoid

thinking them ridiculous and offensive to a sober good man. So that,

in effect, religion, which should most distinguish us from beasts,

and ought most peculiarly to elevate us, as rational creatures, above

brutes, is that wherein men often appear most irrational, and more

senseless than beasts themselves. CREDO, QUIA IMPOSSIBILE EST: I

believe, because it is impossible, might, in a good man, pass for a

sally of zeal; but would prove a very ill rule for men to choose their

opinions or religion by.
