Here is the mode by which superstition, united with politics, exert their efforts to pervert, abuse, and poison the heart of man; the generality of human institutions appear to have only for their object to abase the human character, to render it more flagitiously wicked. Do not then let us be at all astonished if morality is almost every where a barren speculation, from which every one is obliged to deviate in practice, if he will not risk the rendering himself unhappy. Men can only have sound morals, when, renouncing his prejudices, he consults his nature; but the continued impulse which his soul is every moment receiving, on the part of more powerful motives, quickly compels him to forget those ethical rules which nature points out to him. He is continually floating between vice and virtue; we behold him unceasingly in contradiction with himself; if, sometimes, he justly appreciates the value of an honest, upright conduct, experience very soon shews him, that this cannot lead him to any thing, which he has been taught to desire, on the contrary, that it may be an invincible obstacle to the happiness which his heart never ceases for an instant to search after. In corrupt societies it is necessary to become corrupt, in order to become happy. Citizens, led astray at the same time both by their spiritual and temporal guides, neither knew reason nor virtue. The slaves both of their superstitious systems, and of men like themselves, they had all the vices attached to slavery; kept in a perpetual state of infancy, they had neither knowledge nor principles; those who preached virtue to them, knew nothing of it themselves, and could not undeceive them with respect to those baubles in which they had learned to make their happiness consist. In vain they cried out to them to stifle those passions which every thing conspired to unloose: in vain they made the thunder of the gods roll to intimidate men whose tumultuous passions rendered them deaf. It was soon discovered that the gods of the heavens were much less feared than those of the earth; that the favour of the latter procured a much more substantive welfare than the promises of the former; that the riches of this world were more tangible than the treasures reserved for favorites in the next; that it was much more advantageous for men to conform themselves to the views of visible powers than to those of powers who were not within the compass of their visual faculties.
