knowing any thing; or, on the other fide, queftion every thing, and difclaim all knowledge, becaufe fome things are not to be understood. It is of great use to the failor to know the length of his line, though he cannot with it fathom all the depths of the ocean: It is well he knows that it is long enough to reach the bottom at fuch places as are neceffary to direct his voyage, and caution him against running upon fhoals that may ruin him. Our bufinefs here is not to know all things, but those which concern our conduct. If we can find out those measures whereby a rational creature, put in that state which man is in this world, may and ought to govern his opinions, and actions depending thereon, we need not be troubled that fome other things escape our knowledge.

$7. Occafion of this Effay.

THIS was that which gave the first rife to this Effay concerning the Understanding; for I thought that the first step towards fatisfying feveral inquiries the mind of man was very apt to run into, was, to take a furvey of our own understandings, examine our own powers, and fee to what things they were adapted. Till that was done, I fufpected we began at the wrong end, and in vain fought for fatisfaction in a quiet and fure poffeffion of truths that moft concerned us, whilft we let loose our thoughts into the vast ocean of being, as if all that boundless extent were the natural and undoubted poffeffion of our understandings, wherein there was nothing exempt from its decifions, or that escaped its comprehenfion. Thus men, extending their inquiries beyond their capacities, and letting their thoughts wander into thofe depths where they can find no fure footing, it is no wonder that they raife questions, and multiply difputes, which, never coming to any clear refolution, are proper only to continue and increafe their doubts, and to confirm them at laft in perfect fcepticifm;. whereas, were the capacities of our understandings well confidered, the extent of our knowledge once difcovered, and the horizon found which fets the bounds between the enlightened and dark parts of things, be

tween what is and what is not comprehenfible by us, men would perhaps, with lefs fcruple, acquiefce in the avowed ignorance of the one, and employ their thoughts and difcourfe with more advantage and fatisfaction in the other.

§ 8. What Idea stands for.

THUS much I thought neceffary to fay concerning the occafion of this inquiry into human understanding; but before I proceed on to what I have thought on this fubject, I muft here, in the entrance, beg pardon of my reader for the frequent ufe of the word idea, which he will find in the following treatife. It being that term which I think serves best to stand for whatsoever is the object of the understanding when a man thinks, I have used it to exprefs whatever is meant by phantafm, notion, fpecies, or whatever it is which the mind can be employed about in thinking; and I could not avoid frequently using it.

I prefume it will be eafily granted me that there are fuch ideas in mens minds; every one is confcious of them in himself, and mens words and actions will fatisfy him that they are in others.

Our first inquiry, then, shall be, how they come into the mind.

CHAP. II.

NO INNATE PRINCIPLES IN THE MIND.

$1. The way fhown how we come by any Knowledge, fufficient to prove it nat Innate.

IT

T is an established opinion amongst some men, that there are in the understanding certain innate principles, fome primary notions, Kenxin, characters, as it were, ftamped upon the mind of man, which the foul receives in its very first being, and brings into the world with it. It would be fufficient to convince unprejudifed readers of the falfenefs of this fuppofition, if I should only fhow (as I hope I fhall in the following parts of this difcourfe) how men, barely by the use of

their natural faculties, may attain to all the knowledge they have without the help of any innate impreflions, and may arrive at certainty without any fuch original notions or principles: For I imagine any one will easily grant, that it would be impertinent to fuppofe the ideas of colours innate in a creature to whom God hath given fight, and a power to receive them by the eyes from external objects: And no lefs unreasonable would it be to attribute feveral truths to the impreffions of nature and innate characters, when we may observe in ourfelves faculties fit to attain as easy and certain knowledge of them, as if they were originally imprinted on the mind.

But because a man is not permitted without cenfure to follow his own thoughts in the search of truth, when they lead him ever so little out of the common road, I fhall fet down the reasons that made me doubt of the truth of that opinion, as an excufe for my mistake, if I be in one, which I leave to be confidered by those who with me difpofe themselves to embrace truth wherever they find it.

2. General Affent the great Argument.

THERE is nothing more commonly taken for granted, than that there are certain principles, both fpeculative and practical (for they speak of both), univerfally agreed upon by all mankind, which therefore, they argue, muft needs be conftant impreffions, which the fouls of men receive in their firft beings, and which they bring into the world with them, as neceffarily and really as they do any of their inherent faculties.

$3. Univerfal Confent proves nothing Innate. THIS argument, drawn from univerfal confent, has this misfortune in it, that if it were true, in matter of fact, that there were certain truths wherein all mankind agreed, it would not prove them innate, if there can be any other way fhown how men may come to that univerfal agreement in the things they do confent in, which I prefume may be done.

4. What is, is, and, It is impoffible for the fame thing to be, and not to be, not univerfally affented

to.

BUT, which is worfe, this argument of univerfal confent, which is made ufe of to prove innate principles, feems to me a demonstration that there are none fuch, because there are none to which all mankind give an universal affent. I fhall begin with the Speculative, and inftance in those magnified principles of demonftration, Whatsoever is, is, and, It is impoffible for the fame thing to be, and not to be; which of all others I think have the most allowed title to innate. These have fo fettled a reputation of maxims univerfally received, that it will no doubt be thought strange if any one fhould feem to queftion it; but yet I take liberty to fay, that thefe pro- . pofitions are fo far from having an universal affent, that there are a great part of mankind to whom they are not fo much as known.

§ 5. Not on the mind naturally imprinted, because not known to Children, Idiots, &c.

FOR, firft, it is evident that all children and idiots have not the least apprehenfion or thought of them; and the want of that is enough to deftroy that univerfal affent which muft needs be the neceffary concomitant of all innate truths; it feeming to me near a contradiction to fay, that there are truths imprinted on the foul, which it perceives or understands not; imprinting, if it fignify any thing, being nothing else bug the making certain truths to be perceived; for to imprint any thing on the mind, without the mind's perceiving it, feems to me hardly intelligible. If, therefore, children and idiots have fouls, have minds, with thofe impreffions upon them, they muft unavoidably perceive them, and neceffarily know and affent to thefe truths, which fince they do not, it is evident that there are no fuch impreffions; for if they are not notions naturally imprinted, how can they be innate? and if they are notions imprinted, how can they be unknown? To fay a notion is imprinted on the mind, and yet at the fame time to say that the mind is ignorant of it, and never yet took notice of it, is to make

this impression nothing. No propofition can be faid to be in the mind, which it never yet knew, which it was never yet confcious of; for if any one may, then, by the fame reason, all propofitions that are true, and the mind is capable of ever affenting to, may be faid to be in the mind, and to be imprinted, fince, if any one can be faid to be in the mind, which it never yet knew, it must be only because it is capable of knowing it; and. fo the mind is of all truths it ever fhall know: Nay, thus truths may be imprinted on the mind, which it never did, nor ever fhall know; for a man may live long, and die at last in ignorance of many truths which his mind was capable of knowing, and that with cer-tainty: So that, if the capacity of knowing be the natural impreffion contended for, all the truths a man ever comes to know will, by this account, be every one of them innate; and this great point will amount to no more but only to a very improper way of fpeaking, which, whilft it pretends to affert the contrary, fays nothing different from thofe who deny innate principles; for nobody, I think, ever denied that the mind was capable of knowing feveral truths. The capacity, they fay, is innate, the knowledge acquired: But then to what end fuch conteft for certain innate maxins? If truths can be imprinted on the understanding without being perceived, I can fee no difference there can be between any truths the mind is capable of knowing, in refpect of their original; they must all be innate, or all adventitious; in vain fhall a man go about to diftinguish them. He therefore that talks of innate notions in the understanding, cannot (if he intend thereby any diftinct fort of truths) mean fuch truths to be in the understanding as it never perceived, and is yet wholly ignorant of; for if thefe words (to be in the understanding) have any propriety, they fignify to be understood; fo that, to be in the understanding, and not to be understood; to be in the mind, and never to be: perceived, is all one as to fay, any thing is, and is not,. in the mind or understanding. If, therefore, thefe two propofitions, Whatfoever is, is, and, It is impoffible for
