Every one of our passions and affections hath its natural stint and bound, which may easily be exceeded; whereas our enjoyments can possibly be but in a determinate measure and degree.

But to us, probability is the very guide of life.

The object of self-love is expressed in the term self; and every appetite of sense, and every particular affection of the heart, are equally interested or disinterested, because the objects of them all are equally self or somewhat else.

Things and actions are what they are, and the consequences of them will be what they will be: why then should we desire to be deceived?

The only distinct meaning of the word "natural" is stated, fixed, or settled; since what is natural as much requires and presupposes an intelligent agent to render it so, i.e. to effect it continually or at stated times, as what is supernatural or miraculous does to effect it for once.

People might love themselves with the most entire and unbounded affection, and yet be extremely miserable.

Virtue is not to be considered in the light of mere innocence, or abstaining from harm; but as the exertion of our faculties in doing good.
