Where the state begins, individual liberty ceases, and vice versa.

He who desires to worship God must harbor no childish illusions about the matter but bravely renounce his liberty and humanity.

Freedom, morality, and the human dignity of the individual consists precisely in this; that he does good not because he is forced to do so, but because he freely conceives it, wants it, and loves it.

If God really existed, it would be necessary to abolish Him.

I am not myself free or human until or unless I recognize the freedom and humanity of all my fellowmen... I am truly free only when all human beings, men and women, are equally free. The freedom of other men, far from negating or limiting my freedom, is, on the contrary, its necessary premise and confirmation.

Political Freedom without economic equality is a pretense, a fraud, a lie; and the workers want no lying.

If God is, man is a slave; now, man can and must be free; then, God does not exist. I defy anyone whomsoever to avoid this circle; now, therefore, let all choose.
