Under such instructors what could become of youth? The period of juvenility was shamefully sacrificed to superstition. Man, from his earliest infancy, was poisoned with unintelligible notions; fed with mysteries; crammed with fables; drenched with doctrines, in which he was compelled to acquiesce without being able to comprehend. His brain was disturbed with phantoms, alarmed with chimeras, rendered frantic by visions. His genius was cramped with puerile pursuits, mechanical devotions, sacred trifles. Superstition at length so fascinated the human mind, made such mere automata of mankind, that the people consented to address their gods in a dialect they did not themselves understand: women occupied their whole lives in singing Latin, without comprehending a word of the language; the people assisted very punctually, without being competent to explain any part of the worship, under an idea that it was taken kindly they should thus weary themselves; that it was sufficient to shew their persons in the sacred temples, which were beautifully decorated to fascinate their senses. Thus man wasted his most precious moments in absurd customs; spent his life in idle ceremonies; his bead was crowded with sophisms, his mind was loaded with errors; intoxicated with fanaticism, he was the declared enemy to reason; for ever prepossessed against truth, the energy of his soul was resisted by shackles too ponderous for its elasticity; the spring gave way, and he sunk into sloth and wretchedness: from this humiliating state he could never again soar; he could no longer become useful either to himself or to his associates: the importance he attached to his imaginary science, or rather the systematic ignorance which served for its basis, rendered it impossible for the most fertile soil to produce any thing but thorns; for the best proportioned tree to yield any thing but crabs.

Does a superstitious, sacerdotal education, form intrepid citizens, intelligent fathers of families, kind husbands, just masters, faithful servants, loyal subjects, pacific associates? No! it either makes peevish enthusiasts or morose devotees, who are incommodious to themselves, vexatious to others: men without principle, who quickly pour the waters of Lethe over the terrors with which they have been disturbed; who know no moral obligation, who respect no virtue. Thus superstition, elevated above every thing else, held forth the fanatical dogma, "Better to obey the gods than men;" in consequence, man believed he must revolt against his prince, detach himself from his wife, detest his children, estrange himself from his friends, cut the throats of his fellow-citizens, every time they questioned the veracity of his faith: in short, a superstitious education, when it had its effect, only served to corrupt the juvenile heart--to fascinate youthful winds with its pageantry--to degrade the human soul--to make man mistake the duties he owed to himself, his obligations to society, his relations with the beings by whom he was surrounded.
