Human existence is an error...it is bad today and every day it gets worse, until the worst happens.

Because Christian morality leaves animals out of account, they are at once outlawed in philosophical morals; they are mere 'things,' mere means to any ends whatsoever. They can therefore be used for vivisection, hunting, coursing, bullfights, and horse racing, and can be whipped to death as they struggle along with heavy carts of stone. Shame on such a morality that is worthy of pariahs, and that fails to recognize the eternal essence that exists in every living thing, and shines forth with inscrutable significance from all eyes that see the sun!

Just as a stream flows smoothly on as long as it encounters no obstruction, so the nature of man and animal is such that we never really notice or become conscious of what is agreeable to our will; if we are to notice something, our will has to have been thwarted, has to have experienced a shock of some kind.

A sense of humour is the only divine quality of man

Mankind cannot get on without a certain amount of absurdity.

There are 80,000 prostitutes in London alone and what are they, if not bloody sacrifices on the altar of monogamy?

Any foolish boy can stamp on a beetle, but all the professors in the world cannot make a beetle.
