worked, and he took no thought of the morrow. He ate when his disciples asked him to honor their tables; they must have liked his company, for he gave every indication of physiological prosperity. He was not so welcome at home, for he neglected his wife and children; and from Xanthippe's point of view he was a good-for-nothing idler who brought to his family more notoriety than bread. Xanthippe liked to talk almost as much as Socrates did; and they seem to have had some dialogues which Plato failed to record. Yet she, too, loved him, and could not contentedly see him die even after three-score years and ten.
Why did his pupils reverence him so? Perhaps because he was a man as well as a philosopher: he had at great risk saved the life of Alcibiades in battle; and he could drink like a gentleman—without fear and without excess. But no doubt they liked best in him the modesty of his wisdom: he did not claim to have wisdom, but only to seek it lovingly; he was wisdom's amateur, not its professional. It was said that the oracle at Delphi, with unusual good sense, had pronounced him the wisest of the Greeks; and he had interpreted this as an approval of the agnosticism which was the starting-point of his philosophy—"One thing only I know, and that is that I know nothing." Philosophy begins when one learns to doubt—particularly to doubt one's cherished beliefs, one's dogmas and one's axioms. Who knows how these cherished beliefs became certainties with us, and whether some secret wish did not furtively beget them, clothing desire in the dress of thought? There is no real philosophy until the mind turns round and examines itself. Gnothe seauton, said Socrates: Know thyself.
There had been philosophers before him, of course: strong men like Thales and Heraclitus, subtle men like Parmenides and Zeno of Elea, seers like Pythagoras and Empedocles; but for the most part they had been physical philosophers; they had sought for the physis or nature of external things, the laws and constituents of the material and measurable world.
