I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago.

I have great faith in fools self-confidence my friends call it.

All religion, my friend, is simply evolved out of fraud, fear, greed, imagination, and poetry.

There is something in the unselfish and self-sacrificing love of a brute, which goes directly to the heart of him who has had frequent occasion to test the paltry friendship and gossamer fidelity of mere Man.

It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.
