Further, he believed that torture, bodily pain and deadly peril could neither injure nor detract from the happy state and condition of life which, in his opinion, he had attained, and that no sorrow could even cloud the serenity of the Stoic's face and expression. Furthermore, as to ethics, the nature of the human intellect, and the origin of the virtues with their duties and limits, or on the other hand the ills caused by disease and sin, and the wasting and destruction of the soul, he stoutly maintained that absolutely no one else had investigated, understood and mastered all these more thoroughly than himself. As he spoke, he rattled off unfamiliar terms, the catchwords of syllogisms and dialectic tricks, declaring that no one but he could unravel the "master," the "resting," and the "heap" arguments, and other riddles of the kind. In the course of the conversations which are commonly carried on at table after dinner, this fellow often used to prate unseasonably, absurdly, and at immoderate length, on the principles of philosophy, maintaining that compared with himself all the Greek-speaking authorities, all wearers of the toga, and the Latin race in general were ignorant boors. There was with us there at the time a young student of philosophy, of the Stoic school according to his own account, but intolerably loquacious and presuming. And there at that time, while we were with him at the villa called Cephisia, both in the heat of summer and under the burning autumnal sun, we protected ourselves against the trying temperature by the shade of its spacious groves, its long, soft promenades, the cool location of the house, its elegant baths with their abundance of sparkling water, and the charm of the villa as a while, which was everywhere melodious with plashing waters and tuneful birds. While we were students at Athens, Herodes Atticus, a man of consular rank and of true Grecian eloquence, often invited me to his country houses near that city, in company with the honourable Servilianus and several others of our countrymen who had withdrawn from Rome to Greece in quest of culture. § 1.2 The apt use made by Herodes Atticus, the ex-consul, in reply to an arrogant and boastful young fellow, a student of philosophy in appearance only, of the passage in which Epictetus the Stoic humorously set apart the true Stoic from the mob of prating triflers who called themselves Stoics. Then, having ascertained the size of Hercules' foot, he made a calculation of the bodily height suited to that measure, based upon the natural proportion of all parts of the body, and thus arrived at the logical conclusion that Hercules was as much taller than other men as the course at Olympia exceeded the others that had been constructed with the same number of feet. For since it was generally agreed that Hercules paced off the race-course of the stadium at Pisa, near the temple of Olympian Zeus, and made it six hundred feet long, and since the other courses in the land of Greece, constructed later by other men, were indeed six hundred feet in length, but yet were somewhat shorter than that at Olympia, he readily concluded by a process of comparison that the measured length of Hercules' foot was greater than that of other men in the same proportion as the course at Olympia was longer than the other stadia. In the treatise which he wrote on the mental and physical endowment and achievements of Hercules while he was among men, Plutarch says that the philosopher Pythagoras reasoned sagaciously and acutely in determining and measuring the hero's superiority in size and stature. § 1.1 Plutarch's account of the method of comparison and the calculations which the philosopher Pythagoras used in determining the great height of Hercules, while the hero was living among men.
