Conclusion.       §25. To shew how the Understanding proceeds herein, is the design of the
following Discourse; which I shall proceed to, when I have first pre-
mised, 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 falshood, 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 it self, 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 begg’d foundations: Or at least,
— 103 —
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 allow’d 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
Mens 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, concern-
ing a Subject lying somewhat in the dark, without any other design,
than an unbias’d enquiry after Truth.
