Having an active and inquisitive mind, he never, except in his paroxysms of intemperance, was wholly negligent of study: he read what is considered as polite learning so much, that he is mentioned by Wood as the greatest scholar of all the nobility. Sometimes he retired into the country, and amused himself with writing libels, in which he did not pretend to confine himself to truth.
His favourite author in French was Boileau, and in English Cowley.
Thus in a course of drunken gaiety, and gross sensuality, with intervals of study, perhaps, yet more criminal, with an avowed contempt of all decency and order, a total disregard of every moral, and a resolute denial of every religious obligation, he lived worthless and useless, and blazed out his youth and his health in lavish voluptuousness, till, at the age of one-and-thirty, he had exhausted the fund of life, and reduced himself to a state of weakness and decay.
At this time he was led to an acquaintance with Dr. Burnet, to whom he laid open, with great freedom, the tenour of his opinions, and the course of his life, and from whom he received such conviction of the reasonableness of moral duty, and the truth of Christianity, as produced a total change both of his manners and opinions. The account of those salutary conferences is given by Burnet in a book entitled, Some Passages of the Life and Death of John, Earl of Rochester, which the critick ought to read for its elegance, the philosopher for its arguments, and the saint for its piety. It were an injury to the reader to offer him an abridgment.
He died July 26, 1680, before he had completed his thirty-fourth year; and was so worn away by a long illness, that life went out without a struggle.
Lord Rochester was eminent for the vigour of his colloquial wit, and remarkable for many wild pranks and sallies of extravagance. The glare of his general character diffused itself upon his writings; the compositions of a man whose name was heard so often, were certain of attention, and from many readers certain of applause. This blaze of reputation is not yet quite extinguished; and his poetry still retains some splendour beyond that which genius has bestowed.
Wood and Burnet give us reason to believe, that much was imputed to him which he did not write. I know not by whom the original collection was made, or by what authority its genuineness was ascertained. The first edition was published in the year of his death, with an air of concealment, professing, in the titlepage, to be printed at Antwerp.
Of some of the pieces, however, there is no doubt: the Imitation of
Horace's Satire, the Verses to lord Mulgrave, Satire against Man, the
Verses upon Nothing, and, perhaps, some others, are, I believe, genuine;
and, perhaps, most of those which the late collection exhibits[67].
As he cannot be supposed to have found leisure for any course of continued study, his pieces are commonly short, such as one fit of resolution would produce.
His songs have no particular character; they tell, like other songs, in smooth and easy language, of scorn and kindness, dismission and desertion, absence and inconstancy, with the commonplaces of artificial courtship. They are commonly smooth and easy; but have little nature, and little sentiment.
