In Hill’s Life of Dr. Barrow, it is remarked, that this great Mathematician (as well as learned Divine) “was always addicted to poetry, and very much valued that part of it which consists of description.” In like manner, Dr. Rittenhouse delighted in poetic effusions of genius and science. His Eulogist observes, that “the muse of Thomson charmed him most:” indeed, an astronomer, and a man of virtue and taste, could not but be charmed by the chaste and glowing descriptions of that fascinating poet, blended, as they are, with philosophical reflections. Our philosopher, however, greatly admired Milton also: so that these two celebrated votaries of the muses seemed to be his favourites. Why should not these partialities of Rittenhouse be noticed?—when similar observations have been made respecting the characters of other men, eminent in science; as, for example, that the favourite author of Erasmus and the younger Scaliger, was Terence, and that Grotius was an admirer of Terence, Lucan and Horace. Footnote 346: _Nec lusisse pudet_, is an observation which has, in particular instances, been applied to the occasional conduct and disposition of some of the wisest, best, and even gravest characters. Dr. Warton, in remarking on this line of Mr. Pope, viz. “Unthought-of frailties cheat us in the wise,”— says; “Who could imagine that Locke was fond of romances; that Newton once studied astrology; that Dr. Clarke valued himself for his agility, and frequently amused himself, in a private room of his house, in leaping over the tables and chairs; and that our author himself (Mr Pope) was a great epicure.” In our own country, the sage Franklin abounded in anecdote and humour, and thought it not unwise to recreate his mind, at times, with the game of chess: the conversation of Judge Hopkinson was replete with sprightly wit, and he admired well written novels of no immoral tendency; as did also the late Judge Wilson: the illustrious Washington, in his earlier years, enjoyed the pleasures of the festive board, in the society of men of understanding and worth: and no man delighted more in cheerful conversation, and in reading works of fancy and taste, than the philosophic Rittenhouse. The almost universal tendency, in persons of all classes, to an occasional playfulness of temper, even in cases which may sometimes be considered as bordering on weakness, has given the force of a maxim to the observation of the latinists—_Nemo omnibus horis sapit_. Indeed, as a biographer of the celebrated Dr. Clarke has remarked, “to be capable of drawing amusement from trivial circumstances, indicates a heart at ease, and may generally be regarded as the concomitant of virtue.” Footnote 347: See Dr. Rush’s Eulog. on Ritt.
