These principles, universally recognized, are at fault when the question of the existence of God is considered; what has been said of Him is either unintelligible or perfectly contradictory; and for this reason must appear impossible to every man.

Many men without morals have attacked religion because it was contrary to their inclinations. Many wise men have despised it because it seemed to them ridiculous. Many persons have regarded it with indifference, because they have never felt its true disadvantages. But it is as a citizen that I attack it, because it seems to me harmful to the happiness of the state, hostile to the march of the mind of man, and contrary to sound morality, from which the interests of state policy can never be separated.

The Jehovah of the Jews is a suspicious tyrant, who breathes nothing but blood, murder, and carnage, and who demands that they should nourish him with the vapours of animals. The Jupiter of the Pagans is a lascivious monster. The Moloch of the Phoenicians is a cannibal. The pure mind of the Christians resolved, in order to appease his fury, to crucify his own son. The savage god of the Mexicans cannot be satisfied without thousands of mortals which are immolated to his sanguinary appetite.

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.
