      §17. Secondly, That all his Marks are not to be found in each of
his Five Propositions, viz. his First, Second, and Third Marks, agree
— 78 —
perfectly to neither of them; and the First, Second, Third, Fourth,
and Sixth Marks, agree but ill to his Third, Fourth, and Fifth
Propositions. For, besides that, we are assured from History, of
many Men, nay, whole Nations who doubt or disbelieve some or all
of them, I cannot see how the Third, viz. That Vertue joind with
Piety, is the best Worship of God, can be an innate Principle, when the
name, or sound Vertue, is so hard to be understood; liable to so much
uncertainty in its signification; and the thing it stands for, so much
contended about, and difficult to be known. And therefore this can
be but a very uncertain Rule of Humane Practice, and serve but
very little to the conduct of our Lives, and is therefore very unfit
to be assigned as an innate practical Principle.
