How could the human mind progress, while tormented with frightful phantoms, and guided by men, interested in perpetuating its ignorance and fears? Man has been forced to vegetate in his primitive stupidity: he has been taught stories about invisible powers upon whom his happiness was supposed to depend. Occupied solely by his fears, and by unintelligible reveries, he has always been at the mercy of priests, who have reserved to themselves the right of thinking for him, and of directing his actions.

The inward persuasion that we are free to do, or not to do a thing, is but a mere illusion. If we trace the true principle of our actions, we shall find, that they are always necessary consequences of our volitions and desires, which are never in our power. You think yourself free, because you do what you will; but are you free to will, or not to will; to desire, or not to desire? Are not your volitions and desires necessarily excited by objects or qualities totally independent of you?

If the ministers of the Church have often permitted nations to revolt for Heaven's cause, they never allowed them to revolt against real evils or known violencess. It is from Heaven that the chains have come to fetter the minds of mortals.

If we go back to the beginnings of things, we shall always find that ignorance and fear created the gods; that imagination, rapture and deception embellished them; that weakness worships them; that custom spares them; and that tyranny favors them in order to profit from the blindness of men.

People have suffered and become insane for centuries by the thought of eternal punishment after death. Wouldn't it be better to depend on blind matter... than a god who puts out traps for people, invites them to sin, and allows them to sin and commit crimes he could prevent. Only to finally get the barbarian pleasure to punish them in an excessive way, of no use for himself, without them changing their ways and without their example preventing others from committing crimes.

The source of man's unhappiness is his ignorance of Nature.
