The Story of Philosophy《哲学的故事》的第195句：第1章Plato第3节III. The Preparation of Plato第1段第1句：

Plato's meeting with Socrates had been a turning point in his life. He had been brought up in comfort, and perhaps in wealth; he was a handsome and vigorous youth — called Plato, it is said, because of the breadth os his shoulders; he had excelled as a solider, and had twice won prizes at the Isthmian games. Philosophers are not apt to develop out of such an adolescence. But Plato's subtle soul had found a new joy in the "dialectic" game of Socrates; it was a delight to behold the master deflating dogmas and puncturing presumptions with the sharp point of his questions; Plato entered into this sport as he had in coarser kind of wrestling; and under the guidance of the old " gad-fly" (as Socrates called himself) he passed from mere debate to careful analysis and fruitful discussion. He became a very passionate lover of wisdom, and of his teacher. "I thank God," he used to say, "that I was born Greek and not barbarian, free man and not slave, man and not woman; but above all, that I was born in the age of Socrates."
