Before God we are all equally wise - and equally foolish.

The only source of knowledge is experience.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.

It was the experience of mystery - even if mixed with fear - that engendered religion.

That deep emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.

God always takes the simplest way.

If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed.

The fear of death is the most unjustified of all fears, for there's no risk of accident for someone who's dead.

It was the experience of mystery - even if mixed with fear - that engendered religion.
