Chapter I: Introduction
1. SINCE it is the Understanding that sets Man above the rest of sensible Beings, and gives him all the Advantage and Dominion, which he has over them; it is certainly a Subject, even for its Nobleness, worth our Labour to enquire into. The Understanding, like the Eye, whilst it makes us see, and perceive all other Things, takes no notice of it self: And it requires Art and Pains to set it at a distance, and make it its own Object. But whatever be the Difficulties, that lie in the way of this Enquiry; whatever it be, that keeps us so much in the Dark to our selves; sure I am, that all the Light we can let in upon our own Minds; all the Acquaintance we can make with our own Understandings, will not only be very pleasant; but bring us great Advantage, in directing our Thoughts in the search of other Things.
2. This, therefore, being my Purpose to enquire into the Original, Certainty, and Extent of humane Knowledge; together, with the Grounds and Degrees of Belief, Opinion, and Assent; I shall not at present meddle with the Physical Consideration of the Mind; or trouble my self to examine, wherein its Essence consistsā¦. It shall suffice to my present Purpose, to consider the discerning Faculties of a Man, as they are employād about the Objects, which they have to do with: and I shall imagine I have not wholly misimployād my self in the Thoughts I shall have on this Occasion, if in this Historical, plain Method, I can give any Account of the Ways, whereby our Understandings come to attain those Notions of Things we have, and can set down any Measures of the Certainty of our Knowledge, or the Grounds of those Perswasions, which are to be found amongst Men, so various, different, and wholly contradictory; and yet asserted some where or other with such Assurance, and Confidence, that he that shall take a view of the Opinions of Mankind, observe their Opposition, and at the same time, consider the Fondness, and Devotion wherewith they are embracād; the Resolution, and Eagerness, wherewith they are maintainād, may perhaps have Reason to suspect, That either there is no such thing as Truth at all; or that Mankind hath no sufficient Means to attain a certain Knowledge of it.
3. It is therefore worth while, to search out the Bounds between Opinion and Knowledge; and examine by what Measures, in things, whereof we have no certain Knowledge, we ought to regulate our Assent, and moderate our Perswasions. In Order whereunto, I shall pursue this following Method.
First I shall enquire into the Original of those Ideas, Notions, or whatever else you please to call them, which a Man observes, and is conscious to himself he has in his Mind; and the ways whereby the Understanding comes to be furnished with them.
Secondly I shall endeavour to shew, what Knowledge the Understanding hath by those Ideas; and the Certainty, Evidence, and Extent of it.
Thirdly, I shall make some Enquiry into the Nature and Grounds of Faith, or Opinion: whereby I mean that Assent, which we give to any Proposition as true, of whose Truth yet we have no certain Knowledge: And here we shall have Occasion to examine the Reasons and Degrees of Assent.
8. ā¦ Before I proceed on to what I have thought on this Subject, I must here in the Entrance beg pardon of my Reader, for the frequent use of the Word Idea, which he will find in the following Treatise. 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 express whatever is meant by Phantasm, Notion, Species, or whatever it is, which the Mind can be employād about in thinkingā¦.
Chapter II: No innate Principles in the Mind
1. IT is an established Opinion amongst some Men, That there are in the Understanding certain innate Principles; some primary Notions ā¦, Characters, as it were stamped upon the Mind of Man, which the Soul receives in its very first Being; and brings into the World with it. It would be sufficient to convince unprejudiced Readers of the falseness of this Supposition, if I should only shew (as I hope I shall in the following Parts of this Discourse) how Men, barely by the Use of their natural Faculties, may attain to all the Knowledge they have, without the help of any innate Impressions; and may arrive at Certainty, without any such Original Notions or Principles. For I imagine any one will easily grant, That it would be impertinent to suppose, the Ideas of Colours innate in a Creature, to whom God hath given Sight, and a Power to receive them by the Eyes from external Objects: and no less unreasonable would it be to attribute several Truths, to the Impressions of Nature, and innate Characters, when we may observe in our selves Faculties, fit to attain as easie and certain Knowledge of them, as if they were Originally imprinted on the Mindā¦.
2. There is nothing more commonly taken for granted, than that there are certain Principles both Speculative and Practical (for they speak of both) universally agreed upon by all Mankind: which therefore they argue, must needs be the constant Impressions, which the Souls of Men receive in their first Beings, and which they bring into the World with them, as necessarily and really as they do any of their inherent Faculties.
3. This Argument, drawn from Universal Consent, 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 shewn, how Men may come to that Universal Agreement, in the things they do consent in; which I presume may be done.
4. But, which is worse, this Argument of Universal Consent, which is made use of, to prove innate Principles, seems to me a Demonstration that there are none such: Because there are none to which all Mankind give an Universal Assent. I shall begin with the Speculative, and instance in those magnified Principles of Demonstration, Whatsoever is, is; and āTis impossible for the same thing to be, and not to be, which of all others I think have the most allowād Title to innate. These have so setled a Reputation of Maxims universally received, that ātwill, no doubt, be thought strange, if any one should seem to question it. But yet I take liberty to say, That these Propositions are so far from having an universal Assent, that there are a great Part of Mankind, to whom they are not so much as known.
5. For, first ātis evident, that all Children, and Ideots, have not the least Apprehension or Thought of them: and the want of that is enough to destroy that universal Assent, which must needs be the necessary concomitant of all innate Truths: it seeming to me near a Contradiction, to say, that there are Truths imprinted on the Soul, which it perceives or understands not; imprinting, if it signify any thing, being nothing else, but the making certain Truths to be perceived. For to imprint any thing on the Mind without the Mindās perceiving it, seems to me hardly intelligibleā¦. No Proposition can be said to be in the Mind, which it never yet knew, which it was never yet conscious of. For if any one may; then, by the same Reason, all Propositions that are true, and the Mind is capable ever of assenting to, may be said to be in the Mind, and to be imprinted: Since if any one can be said to be in the Mind, which it never yet knew, it must be only because it is capable of knowing it; and so the Mind is of all Truths it ever shall know. Nay, thus Truths may be imprinted on the Mind, which it never did, nor ever shall 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 Certainty. So that if the Capacity of knowing be the natural Impression 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 speaking; which whilst it pretends to assert the contrary, says nothing different from those, who deny innate Principles. For no Body, I think, ever denied, that the Mind was capable of knowing several Truths. The Capacity, they say, is innate, the Knowledge acquired. But then to what end such contest for certain innate Maxims? ā¦
15. The Senses at first let in particular Ideas, and furnish the yet empty Cabinet: And the Mind by degrees growing familiar with some of them, they are lodged in the Memory, and Names got to them. Afterwards the Mind proceeding farther, abstracts them, and by Degrees learns the use of general Names. In this manner the Mind comes to be furnishād with Ideas and Language, the Materials about which to exercise its discursive Faculty: And the use of Reason becomes daily more visible, as these Materials, that give it Employment, increase. But though the having of general Ideas, and the use of general Words and Reason usually grow together: yet, I see not, how this any way proves them innate. The Knowledge of some Truths, I confess, is very early in the Mind; but in a way that chews them not to be innate. For, if we will observe, we shall find it still to be about Ideas, not innate, but acquired: It being about those first, which are imprinted by external Things, with which Infants have earliest to do, and which make the most frequent Impressions on their Senses. In Ideas thus got, the Mind discovers, That some agree, and others differ, probably as soon as it has any use of Memory; as soon as it is able, to retain and receive distinct Ideas. But whether it be then, or no, this is certain, it does so long before it has the use of Words; or comes to that, which we commonly call the use of Reason. For a Child knows as certainly, before it can speak, the difference between the Ideas ...
