O ye, who learned are in Stoic fables, Ye who consign the wisest of all doctrines To your most sacred books; you say that virtue Is the sole good; for that alone can save The life of man, and strongly fenced cities. But if some fancy pleasure their best aim, One of the Muses ’tis who has convinc’d them. He was the original cause of the apathy of Diogenes, and the temperance of Crates, and the patience of Zeno, having himself, as it were, laid the foundations of the city which they afterwards built. And Xenophon says, that in his conversation and society, he was the most delightful of men, and in every respect the most temperate. IX. There are ten volumes of his writings extant.
