There are certain religious facts which, as in external science, have to be perceived, and upon them religion will be built. Of course, the extreme claim that you must believe every dogma of a religion is degrading to the human mind. The man who asks you to believe everything, degrades himself, and, if you believe, degrades you too. The sages of the world have only the right to tell us that they have analysed their minds and have found these facts, and if we do the same we shall also believe, and not before. That is all that there is in religion. But you must always remember this, that as a matter of fact 99.9 per cent of those who attack religion have never analysed their minds, have never struggled to get at the facts. So their arguments do not have any weight against religion, any more than the words of a blind man who cries out, "You are all fools who believe in the sun," would affect us.
