Those Reasons of Doubt which by this Philosopher are admitted as _true_,
were proposed by Me only as _Probable_, and I made use of them not that
I may vend them as _new_, but partly that I may prepare the Minds of my
Readers for the Consideration of Intellectual Things, wherein they seem’d
to me very necessary; And partly that thereby I may shew how firm those
Truths are, which hereafter I lay down, seeing they cannot be Weaken’d by
these Metaphysical Doubts: So, that I never designed to gain any Honor by
repeating them, but I think I could no more omit them, then a Writer in
Physick can pass over the Description of a Disease, Whose Cure he intends
to Teach.
