The Story of Philosophy的第112句：第1章Plato第2节II. Socrates第4段第5句：

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. Gnothi seauton, said Socrates: Know thyself.
