As a member of a state and by nature subject to law, man was essentially a social being. Between all the wise there existed "unanimity," which was "a knowledge of the common good," because their views of life were harmonious. Fools, on the other hand, whose views of life were discordant, were enemies to one another and bent on mutual injury.

As a member of society the sage would play his part in public life. Theoretically this was always true, and practically he would do so, wherever the actual constitution made any tolerable approach to the ideal type. But, if the circumstances were such as to make it certain that his embarking on politics would be of no service to his country, and only a source of danger to himself, then he would refrain. The kind of constitution of which the Stoics most approved was a mixed government containing democratic, aristocratic, and monarchical elements. Where circumstances allowed the sage would act as legislator, and would educate mankind, one way of doing which was by writing books which would prove of profit to the reader.

As a member of existing society the sage would marry and beget children, both for his own sake and for that of his country, on behalf of which, if it were good, he would be ready to suffer and die. Still he would look forward to a better time when, in Zeno's as in Plato's republic, the wise would have women and children in common, when the elders would love all the rising generation equally with parental fondness, and when marital jealousy would be no more.

As being essentially a social being, the sage was endowed not only with the graver political virtues, but also with the graces of life. He was sociable, tactful and stimulating, using conversation as a means for promoting good will and friendship; so far as might be, he was all things to all men, which made him fascinating and charming, insinuating and even wily; he know how to hit the point and to choose the right moment, yet with it all he was plain and unostentatious and simple and unaffected; in particular he never delighted in irony much less in sarcasm.

From the social characteristics of the sage we turn now to a side of his character which appears eminently anti-social. One of his most highly vaunted characteristics was his self-sufficingness. He was to be able to step out of a burning city, coming from the wreck not only of his fortunes, but of his friends and family, and to declare with a smile that he has lost nothing. All that he truly cared for was to be centered in himself. Only thus could he be sure that Fortune would not wrest it from him.

The apathy or passionlessness of the sage is another of his most salient features. The passions being, on Zeno's showing, not natural, but forms of disease, the sage, as being the perfect man, would of course be wholly free from them. They were so many disturbances of the even flow in which his bliss lay. The sage therefore would never be moved by a feeling of favour towards any one; he would never pardon a fault; he would never feel pity; he would never be prevailed upon by entreaty; he would never be stirred to anger.

As to the absence of pity in the sage, the Stoics themselves must have felt some difficulty there since we find Epictetus recommending his hearers to show grief out of sympathy for another, but to be careful not to feel it. The inexorability of the sage was a mere consequence of his calm reasonableness, which would lead him to take the right view from the first. Lastly, the sage would never be stirred to anger. For why should it stir his anger to see another in his ignorance injuring himself?

One more touch has yet to be added to the apathy of the sage. He was impervious to wonder. No miracle of nature could excite his astonishment—no mephitic caverns, which men deemed the mouths of hell, no deep-drawn ebb tides—the standing marvel of the Mediterranean dweller, no hot springs, no spouting jets of fire.

From the absence of passion it is but a step to the absence of error. So we pass now to the infallibility of the sage—a monstrous doctrine which was never broached in the schools before Zeno. The sage, it was maintained, held no opinions, he never repented of his conduct, he was never deceived in anything. Between the daylight of knowledge and darkness of nescience Plato had interposed the twilight of opinion wherein men walked for the most part. Not so however the Stoic sage. Of him it might be said, as Charles Lamb said of the Scotchman with whom he so imperfectly sympathized: "His understanding is always at its meridian—you never see the first dawn, the early streaks." He has no falterings of self suspicion. Surmises, guesses, misgivings, half intuitions, semiconsciousness, partial illuminations, dim instincts, embryo conceptions, have no place in his brain or vocabulary. The twilight of dubiety never falls upon him. Opinion, whether in the form of an ungripped assent, or a weak supposition, was alien from the mental disposition of the serious man. With him there was no hasty or premature assent of the understanding, no forgetfulness, no distrust. He never allowed himself to be overreached or deluded, never had need of an arbiter, never was out in his reckoning nor put out by another. No urbane man ever wandered from his way, or missed his mark, or saw wrong, or heard amiss, or erred in any of his senses; he never conjectured nor thought of a better thing, for the one was a form of imperfect assent, and the other a sign of previous precipitancy. There was with him no change, no retraction, and no tripping. These things were for those whose dogmas could alter. After this it is almost superfluous for us to be assured that the sage never got drunk. Drunkenness, as Zeno pointed out, involved babbling, and of that the sage would never be guilty. He would not, however, altogether eschew banquets. Indeed, the Stoics recognized a virtue under the name of 'conviviality,' which consisted in the proper conduct of them. It was said of Chrysippus that his demeanor was always quiet, even if his gait were unsteady, so that his housekeeper declared that only his legs were drunk.

There were pleasantries even within the school on this subject of infallibility of the sage. Aristo of Chios, while seceding on some other matters, held fast to the dogma that the sage never opined. Whereupon Persaeus played a trick upon him. He made one of two twin brothers deposit a sum of money with him and the other call to reclaim it. The success of the trick however only went to establish that Aristo was not the sage, an admission which each of the Stoics seems to have been ready enough to make on his own part, as the responsibilities of the position were so fatiguing.
