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

Religion is a collective insanity.

Man is only truly free only among equally free men.

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

We must spread our principles, not with words but with deeds, for this is the most popular, the most potent, and the most irresistible form of propaganda.

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.

Mr. Marx does not believe in God, but he believes deeply in himself. His heart is filled not with love but with rancor. He has very little benevolence toward men and becomes... furious and... spiteful... when anyone dares question the omniscience of the divinity whom he adores, that is to say, Mr. Marx himself.
