Plutarch De Genio Socratis 11

[11] Then Galaxidorus: And do you think, Theocritus, that Socrates’s Daemon had some peculiar and extraordinary power? And was it not that this man had by experience confirmed some part of the common necessity which made him, in all obscure and inevident matters, add some weight to the reason that was on one side? For as one grain doth not incline the balance by itself, yet added to one of two weights that are of equal poise, makes the whole incline to that part; thus an omen or the like sign may of itself be too light to draw a grave and settled resolution to any action, yet when two equal reasons draw on either side, if that is added to one, the doubt together with the equality is taken off, so that a motion and inclination to that side is presently produced. Then my father continuing the discourse said: You yourself, Galaxidorus, have heard a Megarian, who had it from Terpsion, say that Socrates’s Daemon was nothing else but the sneezing either of himself or others; for if another sneezed, either before, behind him, or on his right hand, then he pursued his design and went on to action; but if on the left hand, he desisted. One sort of sneezing confirmed him whilst deliberating and not fully resolved; another stopped him when already upon action. But indeed it seems strange that, if sneezing was his only sign, he should not acquaint his familiars with it, but pretend that it was a Daemon that encouraged or forbade him. For that this should proceed from vanity or conceit is not agreeable to the veracity and simplicity of the man; for in those we knew him to be truly great, and far above the generality of mankind. Nor is it likely so grave and wise a man should be disturbed at a casual sound or sneezing, and upon that account leave off what he was about, and give over his premeditated resolutions. Besides all, Socrates’s resolution seems to be altogether vigorous and steady, as begun upon right principles and mature judgment. Thus he voluntarily lived poor all his life, though he had friends that would have been very glad and very willing to relieve him; he still kept close to philosophy, notwithstanding all the discouragements he met with; and at last, when his friends endeavored and very ingeniously contrived his escape, he would not yield to their entreaties, but met death with mirth and cheerfulness, and appeared a man of a steady reason in the greatest extremity. And sure these are not the actions of a man whose designs, when once fixed, could be altered by an omen or a sneeze; but of one who, by some more considerable guidance and impulse, is directed to practise things good and excellent. Besides, I have heard that to some of his friends he foretold the overthrow of the Athenians in Sicily. And before that time, Perilampes the son of Antiphon, being wounded and taken prisoner by us in that pursuit at Delium, as soon as he heard from the ambassadors who came from Athens that Socrates with Alcibiades and Laches fled by Rhegiste and returned safe, blamed himself very much, and blamed also some of his friends and captains of the companies—who together with him were overtaken in their flight about Parnes by our cavalry and slain there—for not obeying Socrates’s Daemon and retreating that way which he led. And this I believe Simmias hath heard as well as I. Yes, replied Simmias, many times, and from many persons; for upon this, Socrates’s Daemon was very much talked of at Athens.
