And if these "first principles"
of knowledge and science are found not to be innate, no other
speculative maxims can (I suppose), with better right pretend to be
so.
Chapter II
No Innate Practical Principles
1. No moral principles so clear and so generally received as the
forementioned speculative maxims. If those speculative Maxims, whereof
we discoursed in the foregoing chapter, have not an actual universal
assent from all mankind, as we there proved, it is much more visible
concerning practical Principles, that they come short of an
universal reception: and I think it will be hard to instance any one
moral rule which can pretend to so general and ready an assent as,
"What is, is"; or to be so manifest a truth as this, that "It is
impossible for the same thing to be and not to be." Whereby it is
evident that they are further removed from a title to be innate; and
the doubt of their being native impressions on the mind is stronger
against those moral principles than the other. Not that it brings
their truth at all in question. They are equally true, though not
equally evident. Those speculative maxims carry their own evidence
with them: but moral principles require reasoning and discourse, and
some exercise of the mind, to discover the certainty of their truth.
