A man must also guard against proposing many problems or proposing them often himself. For this is, in a way, the mark of a man who is taking occasion to show himself off. But to listen good-naturedly when another advances them, marks the considerate gentleman and the scholar. The only exception is in case some matter of his own is troublesome and urgent, some emotion requiring repression, or a disorder requiring relief. For perhaps it may not even be better to conceal ignorance, as Heracleitus Again referred to by Plutarch, Moralia , 439 D and 644 F. Cf. Diels, Fragmente der Vorsokratiker , i. 99. puts it, but to set it forth in public, and cure it. And if some fit of temper, or attack of superstition, or an intense disagreement with members of our own household, or a mad desire born of love, Stirring the heart-strings never stirred before, Again quoted Moralia , 456 C, 501 A, 502 D, and 657 D; cf. Nauck, Trag. Graec. Frag., Adesp. No. 361. brings confusion to our thoughts, we must not run away to other kinds of discourse to escape being taken to task, but we must listen to the discussion of these very matters both at the formal exercises, and after the exercises, when we approach the men privately and question them further. But save us from the contrary course, followed by the majority, who are delighted with the philosophers and admire them when they are discoursing about other people; but if the philosopher leaves the other people alone, and addresses himself frankly and freely to them, and sets them in mind of matters that much concern them, they are annoyed and think him officious. For, as a rule, they imagine that they ought to listen to the philosophers in the schools as they listen to the tragedians in the theatres; but in matters out of school they think the philosophers are no better men than themselves. Now there is some reason that they should feel thus towards the popular lecturers; for when these get up from the speaker’s chair, and put away their books and lecture notes, it is apparent that in the real pursuits of life they are small men and rank lower than the average; but towards philosophers of the real sort it is not right that they have such a feeling, not realizing that seriousness and jest in them, nod, or smile, or frown, and, above all, what they say to each person apart, may yield a return which is profitable for those who have acquired the habit of patient attention.
