The same blindness may be perceived in the science of morals. Superstition, which never had any thing but ignorance for its basis, which never had more than a disordered imagination for its guide, did not found ethics upon man's nature; upon his relations with his fellows; upon those duties which necessarily flow from these relations; it preferred, as more in unison with itself, founding them upon imaginary relations which it pretended subsisted between him and those invisible powers it had so gratuitously imagined; that were delivered by oracles which their priests had the address to make him believe spoke the will of the Divinity: thus, TROPHONIUS, from his cave made affrightened mortals tremble; shook the stoutest nerves; made them turn pale with fear; his miserable, deluded supplicants, who were obliged to sacrifice to him, anointed their bodies with oil, bathed in certain rivers, and after they had offered their cake of honey and received their destiny, became so dejected, so wretchedly forlorn, that to this day their descendants, when they behold a malencholy man, exclaim, "_He has consulted the oracle of Trophonius_." It was these invisible gods, which superstition always paints as furious tyrants, who were declared the arbiters of man's destiny; the models of his conduct: when he was willing to imitate them, when he was willing to conform himself to the lessons of their interpreters, he became wicked, was an unsociable creature, an useless being or else a turbulent maniac--a zealous fanatic. It was these alone who profited by superstition, who advantaged themselves by the darkness in which they contrived to involve the human mind; nations were ignorant of nature; they knew nothing of reason; they understood not truth; they had only a gloomy superstition, without one certain idea of either morals or virtue. When man committed evil against his fellow creature, he believed he had offended these gods; but he also believed himself forgiven, as soon as he had prostrated himself before them; as soon as he had by costly presents gained over the priest to his interest. Thus superstition, far from giving a sure, far from affording a natural, far from introducing a known basis to morals, only rested it on an unsteady foundation; made it consist in ideal duties impossible to be accurately understood. What did I say? It first corrupted him, and his expiations finished by ruining him. Thus when superstition was desirous to combat the unruly passions of man it attempted it in vain; always enthusiastic, ever deprived of experience, it knew nothing of the true remedies: those which it applied were disgusting, only suitable to make the sick revolt against them; it made them pass for divine, because they were not made of man; they were inefficacious, because chimeras could effectuate nothing against those substantive passions to which motives more real, impulsions more powerful, concurred to give birth,
