mind, is either an actual perception, or having been such, is so in the mind that by the memory it can be made an actual perception again. The perception of an idea, without memory, is to the understanding a new idea; with memory, brings a consciousness that it had been in the mind before. What is not actually in view, or in the memory, is not in the mind at all.

I once talked with a blind man, who lost his sight by the small pox, when he was a child, and had no more notion of colours than one born blind. Can any one say that this man had then ideas of colours in his mind, any more than one born blind?

Some sorts of Truths, because of their general and easy reception, have been mistaken for innate: for some Ideas and Notions offer themselves to our faculties more readily, and are more generally received, according as the organs of our bodies and powers of our minds happen to be employed. The greater part of mankind, taking things upon trust, lazily enslave their minds to the dictates of others in doctrines which it is their duty carefully to examine: another part employ their thoughts only about some few things, and never turn them to other enquiries.

"What censure doubting thus of Innate Principles may deserve from men, who will be apt to call it pulling up the old foundations of knowledge and certainty, I cannot tell: I persuade myself, at least,

that the way I have pursued, being conformable to Truth, lays those foundations surer. This, I am certain, I have not made it my business, either to quit or follow any authority in the ensuing discourse: Truth has been my only aim; and wherever that has appeared to lead, my thoughts have impartially followed, without minding whether the footsteps of any other lay that way, or no. Not that I want a due respect to other men's opinions; but after all, the greatest reverence is due to Truth; and I hope it will not be thought arrogance to say, that perhaps we should make greater progress in the discovery of rational and contemplative knowledge, if we sought it in the fountain, in the Consideration of Things themselves; and made use rather of our own thoughts than other men's to find it. For, I think, we may as rationally hope to see with other men's eyes as to know by other men's understandings. So much as we ourselves consider and comprehend of truth and reason, so much we possess of real and true knowledge. The floating of other men's opinions in our brains makes us not one jot the more knowing, though they happen to be true. What in them was Science, is in

us but Opiniatrety; whilst we give up our assent only to reverend Names, and do not, as they did, employ our own reason to understand those Truths which gave them reputation. Aristotle was certainly a knowing man, but no body ever thought him so, be

cause he blindly embraced and confidently vented the opinions of another. And if the taking up of another's principles, without examining them, made not him a philosopher, I suppose it will hardly make any body else so. In the Sciences, every one has so much, as he really knows and comprehends: what he believes only, and takes upon trust, are but shreads; which, however well in the whole piece, make no considerable addition to his stock who gathers them. Such borrowed wealth, like fairy-money, though it were gold in the hand from which he received it, will be but leaves and dust when it comes to use.

When men have found some general propositions that could not be doubted of, as soon as understood, it was, I know, a short and easy way to conclude them innate. This being once received, it eased the lazy from the pains of search, and stopt the enquiry of the doubtful, concerning all that was once stiled Innate and it was of no small advantage to those who affected to be masters and teachers, to make this the Principle of Principles, that Principles must not be questioned: for having once established this tenet, that there are Innate Principles, it put their followers upon a necessity of receiving some doctrines as such; which was to take them off from the use of their own reason and judgment, and put them upon believing and taking them upon trust without farther examination: in which posture of

blind credulity, they might be more easily governed by, and made useful to some sort of men, who had the skill and office to principle and guide them. Nor is it a small power it gives one man over another, to have the authority to be the dictator of principles, and teacher of unquestionable truths: and to make a man swallow that for an Innate Principle, which may serve to his purpose who teaches them. Whereas, had they examined the ways whereby men came to the knowledge of many universal truths, they would have found them to result in the minds of men, from the being of things themselves, when duly considered; and that they were discovered by the application of those faculties that were fitted by Nature to receive and judge of them, when duly enployed about them.

To shew how the understanding proceeds herein, is the design of the following discourse; which I shall proceed to, when I have first premised, that hitherto to clear my way to those foundations, which I conceive are the only true ones, whereon to establish those notions we can have of our own knowledge, it hath been necessary for me to give an account of the reasons I had to doubt of Innate Principles and since the arguments which are against them do some of them rise from common received opinions, I have been forced to take several things for granted, which is hardly avoidable to any

:

one, whose task it is to shew the falsehood or improbability of any tenet: it happening in controversial discourses, as it does in assaulting of towns; where if the ground be but firm, whereon the batteries are erected, there is no farther enquiry of whom it is borrowed, nor whom it belongs to, so it affords but a fit rise for the present purpose. But in the future part of this discourse, designing to raise an edifice uniform, and consistent with itself, as far as my own experience and observation will assist me, I hope to erect it on such a basis, that I shall not need to shore it up with props and buttresses, leaning on borrowed or begged, foundations: or at least, if mine prove a castle in the air, I will endeavour it shall be all of a piece, and hang together. Wherein I warn the reader, not to expect undeniable cogent demonstrations, unless I may be allowed the privilege, not seldom assumed by others, to take my principles for granted; and then I doubt not, but I can demonstrate too. All that I shall say for the principles I proceed on, is, that I can only appeal to men's own unprejudiced experience and observation, whether they be true or no; and this is enough for a man who professes no more, than to lay down candidly and freely his own conjectures concerning a subject lying somewhat in the dark, without any other design than an unbiass'd enquiry after Truth."
