Can a society in which thought and technique are scientific persist for a long period, as, for example, ancient Egypt persisted, or does it necessarily contain within itself forces which must bring either decay or explosion?

An atheist, like a Christian, holds that we can know whether or not there is a God. The Christian holds that we can know there is a God; the atheist, that we can know there is not. The Agnostic suspends judgment, saying that there are not sufficient grounds either for affirmation or for denial. At the same time, an Agnostic may hold that the existence of God, though not impossible, is very improbable; he may even hold it so improbable that it is not worth considering in practice. In that case, he is not far removed from atheism.

Religion is based ... mainly upon fear ... fear of the mysterious, fear of defeat, fear of death.

These illustrations suggest four general maxims[...]. The first is: remember that your motives are not always as altruistic as they seem to yourself. The second is: don't over-estimate your own merits. The third is: don't expect others to take as much interest in you as you do yourself. And the fourth is: don't imagine that most people give enough thought to you to have any special desire to persecute you.

Be isolated, be ignored, be attacked, be in doubt, be frightened, but do not be silenced.

The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.
