Few men speak humbly of humility, chastely of chastity, skeptically of skepticism. - Blaise Pascal

Men are so necessarily mad, that not to be mad would amount to another form of madness.

Nothing is good but mediocrity. The majority has settled that, and finds fault with him who escapes it at whichever end.

We are so unhappy that we can only enjoy something which we should be annoyed to see go wrong, and that can and does constantly happen to thousands of things. Anyone who found the secret of rejoicing when things go well without being annoyed when they go badly would have found the point. It is perpetual motion.
