From this filthy Cocytus flowed those streams of impurity which disgraced France during the reign of Louis XV., and which, notwithstanding the example of a prince who was himself a model of domestic virtue, continued in that of Louis XVI. to infect society, morals, and, above all, literature. We do not here allude merely to those lighter pieces of indecency in which humour and fancy outrun the bounds of delicacy. These are to be found in the literature of most nations, and are generally in the hands of mere libertines and men of pleasure, so well acquainted with the practice of vice, that the theory cannot make them worse than they are. But there was a strain of voluptuous and seducing immorality which pervaded not only the lighter and gayer compositions of the French, but tinged the writings of those who called the world to admire them as poets of the highest mood, or to listen as to philosophers of the most lofty pretensions. Voltaire, Rousseau, Diderot, Montesquieu,--names which France must always esteem her highest honour,--were so guilty in this particular, that the young and virtuous must either altogether abstain from the works which are every where the topic of ordinary discussion and admiration, or must peruse much that is hurtful to delicacy, and dangerous to morals, in the formation of their future character. The latter alternative was universally adopted; for the curious will read as the thirsty will drink, though the cup and page be polluted. So far had an indifference to delicacy influenced the society of France, and so widely spread was this habitual impurity of language and ideas, especially among those who pretended to philosophy, that Madame Roland, a woman admirable for courage and talents, and not, so far as appears, vicious in her private morals, not only mentions the profligate novels of Louvet as replete with the graces of imagination, the salt of criticism, and the tone of philosophy, but affords the public, in her own person, details with which a courtezan of the higher class should be unwilling to season her private conversation.[30]
