I could be spending time looking through a telescope or into a microscope and finding out the most extraordinary, wonderful things, but people say faith can move mountains. Faith in what, by the way? You haven't said.

The true essence of a dictatorship is in fact not its regularity but its unpredictability and caprice; those who live under it must never be able to relax, must never be quite sure if they have followed the rules correctly or not.

My favorite time in the cycles of public life is the time when the Pope is dead and they haven't elected a new one. There's no one in the world who is infallible for those weeks. And you know, I don't miss it.

Part of the function of memory is to forget; the omni-retentive mind will break down and produce at best an idiot savant who can recite a telephone book, and at worst a person to whom every grudge and slight is as yesterday's.

Beware the irrational, however seductive. Shun the 'transcendent' and all who invite you to subordinate or annihilate yourself. Distrust compassion; prefer dignity for yourself and others. Don't be afraid to be thought arrogant or selfish. Picture all experts as if they were mammals. Never be a spectator of unfairness or stupidity. Seek out argument and disputation for their own sake; the grave will supply plenty of time for silence. Suspect your own motives, and all excuses. Do not live for others any more than you would expect others to live for you.
