Most of the greatest evils that man has inflicted upon man have come through people feeling quite certain about something which, in fact, was false. - Bertrand Russell

Religion, since it has its source in terror, has dignified certain kinds of fear and made people think them not disgraceful. In this it has done mankind a great disservice: all fear is bad. I believe that when I die I shall rot, and nothing of my ego will survive. I am not young and I love life. But I should scorn to shiver with terror at the thought of annihilation. Happiness is nonetheless true happiness because it must come to an end, nor do thought and love lose their value because they are not everlasting. Many a man has borne himself proudly on the scaffold; surely the same pride should teach us to think truly about man's place in the world. Even if the open windows of science at first make us shiver after the cosy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigour, and the great spaces have a splendour of their own.

All serious innovation is only rendered possible by some accident
enabling unpopular persons to survive.

There is something feeble and a little contemptible about a man who cannot face the perils of life without the help of comfortable myths. Almost inevitably some part of him is aware that they are myths and that he believes them only because they are comforting. But he dare not face this thought! Moreover, since he is aware, however dimly, that his opinions are not rational, he becomes furious when they are disputed.
