In love we often doubt what we most believe.

Conceit causes more conversation than wit.

As we grow older we grow both more foolish and wiser at the same time.

When we enlarge upon the affection our friends have for us, this is very often not so much out of a sense of gratitude as from a desire to persuade people of our own great worth, that can deserve so much kindness.

The name and pretense of virtue is as serviceable to self-interest as are real vices.

True love is like ghosts, which everyone talks about and few have seen.

What men call friendship is no more than a partnership, a mutual care of interests, an exchange of favors - in a word, it is a sort of traffic, in which self-love ever proposes to be the gainer.
