And so, to those tempted by despair, I say: Remind yourself that the world is what we make it, and that to the making of it each one of us can contribute something. This thought makes hope possible: and in this hope, though life will still be painful, it will be no longer purposeless. — Bertrand Russell, The Wisdom of Bertrand Russell, A Philosophy for You in These Times (1941), p. 56.

Tolerance, as a practical maxim, has two sources: on the one hand, the realization that we may be mistaken; on the other hand, the belief that free discussion will promote the view we favour. This latter opinion must be held by anyone whose opinions are formed on rational grounds. Dogmatists, on the contrary, fear that free discussion would show their beliefs to be groundless, and that is why they always favour censorship. — Bertrand Russell, BBC broadcast transcript, published as Why Fanaticism Brings Defeat, The Listener 40 (23 Sep 1948), pp. 452-3.
