That good disposition which boasts of being most tender is often stifled by the least urging of self-interest.

When we are in love we often doubt that which we most believe.

How is it that we remember the least triviality that happens to us, and yet not remember how often we have recounted it to the same person?

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

Self-interest makes some people blind, and others sharp-sighted.

There is no better proof of a man's being truly good than his desiring to be constantly under the observation of good men.
