From enthusiasm to imposture the step is perilous and slippery; the demon of Socrates affords a memorable instance how a wise man may deceive himself, how a good man may deceive others, how the conscience may slumber in a mixed middle state between self-illusion and voluntary fraud. Charity may believe that the original motives of Mohammed were those of pure and genuine benevolence; but a human missionary is incapable of cherishing the obstinate unbelievers who reject his claims, despise his arguments, and persecute his life; he might forgive his personal adversaries, he may lawfully hate the enemies of God; the stern passions of pride and revenge were kindled in the bosom of Mohammed, and he sighed, like the prophet of Nineveh, for the destruction of the rebels whom he had condemned. The injustice of Mecca and the choice of Medina transformed the citizen into a prince, the humble preacher into the leader of armies; but his sword was consecrated by the example of the saints; and the same God who afflicts a sinful world with pestilence and earthquakes might inspire for their conversion or chastisement the valour of his servants. In the exercise of political government he was compelled to abate the stern rigour of fanaticism, to comply, in some measure, with the prejudices and passions of his followers, and to employ even the vices of mankind as the instruments of their salvation. The use of fraud and perfidy, of cruelty and injustice, were often subservient to the propagation of the faith; and Mohammed commanded or approved the assassination of the Jews and idolaters who had escaped from the field of battle. By the repetition of such acts, the character of Mohammed must have been gradually stained; and the influence of such pernicious habits would be poorly compensated by the practice of the personal and social virtues, which are necessary to maintain the reputation of a prophet among his sectaries and friends. Of his last years, ambition was the ruling passion; and a politician will suspect that he secretly smiled (the victorious impostor!) at the enthusiasm of his youth and the credulity of his proselytes. A philosopher would observe that their credulity and his success would tend more strongly to fortify the assurance of his divine mission, that his interest and religion were inseparably connected, and that his conscience would be soothed by the persuasion that he alone was absolved by the Deity from the obligation of positive and moral laws. If he retained any vestige of his native innocence, the sins of Mohammed may be allowed as the evidence of his sincerity. In the support of truth, the arts of fraud and fiction may be deemed less criminal; and he would have started at the foulness of the means, had he not been satisfied of the importance and justice of the end. The decree of Mohammed that, in the sale of captives, the mothers should never be separated from their children, may suspend or moderate the censure of the historian.
