I have sent you in a packet which your Leipsig acquaintance, Duval, sends to his correspondent at Rome, Lord Bolingbroke's book,--["Letters on the Spirit of Patriotism," on the Idea of a Patriot King which he published about a year ago.]--I desire that you will read it over and over again, with particular attention to the style, and to all those beauties of oratory with which it is adorned. Till I read that book, I confess I did not know all the extent and powers of the English language. Lord Bolingbroke has both a tongue and a pen to persuade; his manner of speaking in private conversation is full as elegant as his writings; whatever subject he either speaks or writes upon, he adorns with the most splendid eloquence; not a studied or labored eloquence, but such a flowing happiness of diction, which (from care perhaps at first) is become so habitual to him, that even his most familiar conversations, if taken down in writing, would bear the press, without the least correction either as to method or style. If his conduct, in the former part of his life, had been equal to all his natural and acquired talents, he would most justly have merited the epithet of all-accomplished. He is himself sensible of his past errors: those violent passions which seduced him in his youth, have now subsided by age; and take him as he is now, the character of all-accomplished is more his due than any man's I ever knew in my life. But he has been a most mortifying instance of the violence of human passions and of the weakness of the most exalted human reason. His virtues and his vices, his reason and his passions, did not blend themselves by a gradation of tints, but formed a shining and sudden contrast. Here the darkest, there the most splendid colors; and both rendered more shining from their proximity. Impetuosity, excess, and almost extravagance, characterized not only his passions, but even his senses. His youth was distinguished by all the tumult and storm of pleasures, in which he most licentiously triumphed, disdaining all decorum. His fine imagination has often been heated and exhausted, with his body, in celebrating and deifying the prostitute of the night; and his convivial joys were pushed to all the extravagance of frantic Bacchanals. Those passions were interrupted but by a stronger ambition. The former impaired both his constitution and his character, but the latter destroyed both his fortune and his reputation.
