The Story of Philosophy的第124句：第1章Plato第2节II. Socrates第6段第6句：

So he went about prying into the human soul, uncovering assumptions and questioning certainties. If men discoursed too readily of justice, he asked them, quietly, tò tí—what is it? What do you mean by these abstract words with which you so easily settle the problems of life and death? What do you mean by honor, virtue, morality, patriotism? What do you mean by yourself? It was with such moral and psychological questions that Socrates loved to deal. Some who suffered from this “Socratic method,” this demand for accurate definitions, and clear thinking, and exact analysis, objected that he asked more than he answered, and left men’s minds more confused than before. Nevertheless he bequeathed to philosophy two very definite answers to two of our most difficult problems— What is the meaning of virtue? and What is the best state?
