Thus man was, and always remained, a child without experience, a slave without courage, a loggerhead who feared to reason, and who could never escape from the labyrinth into which his ancestors had misled him; he felt compelled to groan under the yoke of his Gods, of whom he knew nothing except the fabulous accounts of their ministers. These, after having fettered him by the ties of opinion, have remained his masters or delivered him up defenseless to the absolute power of tyrants, no less terrible than the Gods, of whom they were the representatives upon the earth. Oppressed by the double yoke of spiritual and temporal power, it was impossible for the people to instruct themselves and to work for their own welfare. Thus, religion, politics, and morals became sanctuaries, into which the profane were not permitted to enter. Men had no other morality than that which their legislators and their priests claimed as descended from unknown empyrean regions. The human mind, perplexed by these theological opinions, misunderstood itself, doubted its own powers, mistrusted experience, feared truth, disdained its reason, and left it to blindly follow authority. Man was a pure machine in the hands of his tyrants and his priests, who alone had the right to regulate his movements. Always treated as a slave, he had at all times and in all places the vices and dispositions of a slave. These are the true sources of the corruption of habits, to which religion never opposes anything but ideal and ineffectual obstacles; ignorance and servitude have a tendency to make men wicked and unhappy. Science, reason, liberty, alone can reform them and render them more happy; but everything conspires to blind them and to confirm them in their blindness. The priests deceive them, tyrants corrupt them in order to subjugate them more easily. Tyranny has been, and will always be, the chief source of the depraved morals and habitual calamities of the people. These, almost always fascinated by their religious notions or by metaphysical fictions, instead of looking upon the natural and visible causes of their miseries, attribute their vices to the imperfections of their nature, and their misfortunes to the anger of their Gods; they offer to Heaven vows, sacrifices, and presents, in order to put an end to their misfortunes, which are really due only to the negligence, the ignorance, and to the perversity of their guides, to the folly of their institutions, to their foolish customs, to their false opinions, to their unreasonable laws, and especially to their want of enlightenment. Let the mind be filled early with true ideas; let man's reason be cultivated; let justice govern him; and there will be no need of opposing to his passions the powerless barrier of the fear of Gods. Men will be good when they are well taught, well governed, chastised or censured for the evil, and justly rewarded for the good which they have done to their fellow-citizens.
