We are materialists and atheists, and we glory in the fact.

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.

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.

To my utter despair I have discovered, and discover every day anew, that there is in the masses no revolutionary idea or hope or passion.

But here steps in Satan, the eternal rebel, the first freethinker and the emancipator of worlds. He makes man ashamed of his bestial ignorance and obedience; he emancipates him, stamps upon his brow the seal of liberty and humanity, in urging him to disobey and eat of the fruit of knowledge.

Everything will pass, and the world will perish but the Ninth Symphony will remain.

Anyone who makes plans for after the revolution is a reactionary.
