is apt to content itself with any excuse, will pardon me, if mine has prevailed on me, where, I think, I have a very good one. I will not therefore allege in my defence, that the same notion, having different respects, may be convenient or necessary to prove or illustrate several parts of the same discourse; and that so it has happened in many parts of this: but waving that, I shall frankly avow, that I have sometimes dwelt long upon the same argument, and expressed it different ways, with a quite different design. I pretend not to publish this Essay for the information of men of large thoughts, and quick apprehensions; to such masters of knowledge I profess myself a scholar, and therefore warn them beforehand not to expect any thing here, but what, being spun out of my own coarse thoughts, is fitted to men of my own size; to whom, perhaps, it will not be unacceptable, that I have taken some pains to make plain and familiar to their thoughts some truths, which established prejudice, or the abstractedness of the ideas themselves, might render difficult. Some objects had need be turned on every side: and when the notion is new, as I confess some of these are to me, or out of the ordinary road, as I suspect they will appear to others; it is not one simple view of it, that will gain it admittance into every understanding, or fix it there with a clear and lasting impression.
