their argument stands thus: "the principles which all mankind allow for true are innate; those that men of right reason admit, are the principles allowed by all mankind; we, and those of our mind, are men of reason; therefore we agreeing, our principles are innate;" which is a very pretty way of arguing, and a short cut to infallibility. For otherwise it will be very hard to understand, how there be some principles, which all men do acknowledge and agree in; and yet there are none of those principles, which are not by depraved custom, and ill education, blotted out of the minds of many men: which is to say, that all men admit, but yet many men do deny, and dissent from them. And indeed the supposition of such first principles will serve us to very little purpose; and we shall be as much at a loss with, as without them, if they may, by any human power, such as is the will of our teachers, or opinions of our companions, be altered or lost in us: and notwithstanding all this boast of first principles and innate light, we shall be as much in the dark and uncertainty as if there were no such thing at all: it being all one, to have no rule, and one that will warp any way; or, amongst various and contrary rules, not to know which is the right. But concerning innate principles, I desire these men to say, whether they can, or cannot, by education and custom, be blurred and blotted out: if they cannot, we must find them in all mankind alike, and they must be clear in every body: and if they may suffer variation from adventitious notions, we must then find them clearest and most perspicuous, nearest the fountain, in children and illiterate people, who have received least impression from foreign opinions. Let them take which side they please, they will certainly find it inconsistent with visible matter of fact and daily observation.
Contrary principles in the world.§ 21. I easily grant that there are great numbers of opinions, which, by men of different countries, educations, and tem-
