[Footnote 161: If we read the treatise of Plutarch, [Greek: Peri\ Stôi/kôn e)nantiôma/tôn] (c. 2-3, p. 1033 C-D), we shall see that the Stoic writers, Zeno, Kleanthes, Chrysippus, Diogenes, Antipater, all of them earnestly recommended a life of active citizenship and laborious political duty, as incumbent upon philosophers not less than upon others; and that they treated with contempt a life of literary leisure and speculation. Chrysippus explicitly declared [Greek: ou)de\n diaphe/rein to\n scholastiko\n bi/on tou= ê(donikou=] _i. e._ that the speculative philosopher who kept aloof from political activity, was in substance a follower of Epikurus. Tacitus holds much the same language (Hist. iv. 5) when he says about Helvidius Priscus:--"ingenium illustre altioribus studiis juvenis admodum dedit: non, ut plerique, ut nomine magnifico segne otium velaret, sed quo constantior adversus fortuita rempublicam capesseret," &c. The contradiction which Plutarch notes is, that these very Stoic philosophers (Chrysippus and the others) who affected to despise all modes of life except active civic duty--were themselves, all, men of literary leisure, spending their lives away from their native cities, in writing and talking philosophy. The same might have been said about Sokrates and Plato (except as to leaving their native cities), both of whom incurred the same reproach for inactivity as Sokrates here addresses to Aristippus.] [Side-note: Language held by Aristippus--his scheme of life.]
