The first book _De Republicâ_, which was one of those read by Cicero to Sallust and some other friends, in his Tusculan villa, is, as already mentioned, imperfect at the commencement. Not much, however, seems to be wanting, and a prologue of considerable length still remains, in which the author (pleading, perhaps, his own cause) combats the opinions of philosophers, who, preferring a contemplative to an active life, blame those who engage in public affairs. To the former he opposes the example of many wise and great men, and answers those objections to a busy political life, which have been repeatedly urged against it. This prologue contains some good reasoning, and, like all the writings of its illustrious author, displays a noble patriotic feeling. He remarks, that he had entered into this discussion as introductory to a book concerning the republic, since it seemed proper, as prefatory to such a work, to combat the sentiments of those who deny that a philosopher should be a statesman. “As to the work itself,” says he, addressing (as I have supposed) his brother, “I shall lay down nothing new or peculiar to myself, but shall repeat a discussion which once took place among the most illustrious men of their age, and the wisest of our state, such as it was related to myself, and to you when a youth, by P. Rutilius Rufus, when we were with him some days at Smyrna—in which discussion nothing of importance to the right constitution of a commonwealth, appears to have been omitted.” The author then proceeds to mention, that during the consulship of Tuditanus and Aquilius, (as he had heard from Rufus,) the younger Scipio Africanus determined to pass the Latin festivals (Latinæ Feriæ) in his gardens, where some of his most intimate friends had promised to visit him. The first of these who makes his appearance is his nephew, Quintus Tubero, a person devoted to the Stoical philosophy, and noted for the austerity of his manners. A remark which Tubero makes about two suns, a prodigy which, it seems, had lately appeared in the heavens, leads Scipio to praise Socrates for his abandonment of physical pursuits, as neither very useful to man, nor capable of being thoroughly investigated—a sentiment (by the way) which, with all due submission to the Greek philosopher, does little credit to his sagacity, as physical inquiries have been not only highly useful to mankind, but are almost the only subjects in which accurate science has been attained. Furius, Philus, and Rutilius, who is stated to have related the discussion to Cicero, now enter, and, at last, comes Lælius, attended by his friend, Spurius Mummius, (brother to the well-known connoisseur in the fine arts who took Corinth,) and by his two sons-in-law, C. Fannius and Q. Scævola. After saluting them, Scipio, as it was now winter, takes them to a sunny spot, in a meadow, and in proceeding thither the party is joined by M. Manilius.
