Whatever latitude an absolute monarch may assume in his own conduct, whatever indulgence he may claim for his own passions, it is undoubtedly his interest that all his subjects should respect the natural and civil obligations of society. But the operation of the wisest laws is imperfect and precarious. They seldom inspire virtue, they cannot always restrain vice. Their power is insufficient to prohibit all that they condemn, nor can they always punish the actions which they prohibit. The legislators of antiquity had summoned to their aid the powers of education and of opinion. But every principle which had once maintained the vigor and purity of Rome and Sparta, was long since extinguished in a declining and despotic empire. Philosophy still exercised her temperate sway over the human mind, but the cause of virtue derived very feeble support from the influence of the Pagan superstition. Under these discouraging circumstances, a prudent magistrate might observe with pleasure the progress of a religion which diffused among the people a pure, benevolent, and universal system of ethics, adapted to every duty and every condition of life; recommended as the will and reason of the
