Laughter is the corrective force which prevents us from becoming cranks.

There are manifold tones of mental life, or, in other words, our psychic life may be lived at different heights, now nearer to action, now further removed from it, according to the degree of our attention to life.

There is nothing in philosophy which could not be said in everyday language.

It is the very essence of intelligence to coordinate means with a view to a remote end, and to undertake what it does not feel absolutely sure of carrying out.

In reality, the past is preserved by itself automatically.

It is with our entire past ... that we desire, will and act ... from this survival of the past it follows that consciousness cannot go through the same state twice. The circumstances may still be the same, but they will act no longer on the same person ... that is why our duration is irreversible.

The only cure for vanity is laughter. And the only fault that's laughable is vanity.
