My objection to Christianity is that it is infinitely cruel, infinitely selfish, and, I might add, infinitely absurd.

Age after age, the strong have trampled upon the weak; the crafty and heartless have ensnared and enslaved the simple and innocent, and nowhere, in all the annals of mankind, has any god succored the oppressed

Courage without conscience is a wild beast.

The intellectual advancement of man depends on how often he can exchange an old superstition for a new truth.

Liberty a word without which all other words are vain.

Happiness is not a reward - it is a consequence. Suffering is not a punishment - it is a result.

Mental slavery is mental death, and every man who has given up his intellectual freedom is the living coffin of his dead soul.
