In spite of all the yearnings of men, no one can produce a single fact or reason to support the belief in God and in personal immortality.

I have lived my life, and I have fought my battles, not against the weak and the poor - anybody can do that - but against power, against injustice, against oppression, and I have asked no odds from them, and I never shall.
