I have not the slightest confidence in 'spiritual manifestations.'

No one, in the world's whole history, ever attempted to substantiate a truth by a miracle. Truth scorns the assistance of miracle. Nothing but falsehood ever attested itself by signs and wonders. No miracle ever was performed, and no sane man ever thought he had performed one, and until one is performed, there can be no evidence of the existence of any power superior to, and independent of nature.

If we are immortal it is a fact in nature, and we are not indebted to priests for it, nor to bibles for it, and it cannot be destroyed by unbelief.

Nothing could be more dangerous to the existence of this Republic than to introduce religion into politics

The true civilization is where every man gives to every other every right that he claims for himself.

Environment is a sculptor - a painter. If we had been born in Constantinople, then most of us would have said: 'There is no God but Allah, and Mohammed is his prophet.' If our parents had lived on the banks of the Ganges, we would have been worshipers of Siva, longing for the heaven of Nirvana. As a rule, children love their parents, believe what they teach, and take great pride in saying that the religion of mother is good enough for them.

Injustice upon earth renders the justice of of heaven impossible.
