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.
