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 he 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 nobody ever thought him so because he blindly embraced, or confidently vented, the opinions of another. And if the taking up 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 shreds; 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.
Whence the opinion of innate principles.§ 24. 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 stopped the inquiry of the doubtful concerning all that was once styled 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 on 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
