SOCRATES: […] if I were asking you what is the nature of bees, and you said that they are many and of all kinds, what would you answer if I asked you: “Do you mean that they are many and varied and different from one another insofar as they are bees? Or are they no different in that regard, but in some other respect, in their beauty, for example, or their size or in some other such way?” Tell me, what would you answer if thus questioned?
MENO: I would say that they do not differ from one another in being bees.
SOCRATES: If I went on to say: “Tell me, what is this very thing, Meno, in which they are all the same and do not differ from one another?” Would you be able to tell me?
MENO: I would.
SOCRATES: The same is true in the case of the virtues.
