triangle is capable being inscribed in a certain circle (Or, whether a certain area is capable of being inscribed as a triangle in a certain circle.), will reply: ‘I cannot tell you as yet; but I will offer a hypothesis which may assist us in forming a conclusion: If the figure be such that when you have produced a given side of it (Or, when you apply it to the given line, i.e. the diameter of the circle (autou).), the given area of the triangle falls short by an area corresponding to the part produced (Or, similar to the area so applied.), then one consequence follows, and if this is impossible then some other; and therefore I wish to assume a hypothesis before I tell you whether this triangle is capable of being inscribed in the circle’:—that is a geometrical hypothesis. And we too, as we know not the nature and qualities of virtue, must ask, whether virtue is or is not taught, under a hypothesis: as thus, if virtue is of such a class of mental goods, will it be taught or not? Let the first hypothesis be that virtue is or is not knowledge,—in that case will it be taught or not? or, as we were just now saying, ‘remembered’? For there is no use in disputing about the name. But is virtue taught or not? or rather, does not every one see that knowledge alone is taught? MENO: I agree. SOCRATES: Then if virtue is knowledge, virtue will be taught? MENO: Certainly. SOCRATES: Then now we have made a quick end of this question: if virtue is of such a nature, it will be taught; and if not, not? MENO: Certainly. SOCRATES: The next question is, whether virtue is knowledge or of another species? MENO: Yes, that appears to be the question which comes next in order. SOCRATES: Do we not say that virtue is a good?—This is a hypothesis which is not set aside. MENO: Certainly. SOCRATES: Now, if there be any sort of good which is distinct from knowledge, virtue may be that good; but if knowledge embraces all good, then we shall be right in thinking that virtue is knowledge? MENO: True. SOCRATES: And virtue makes us good? MENO: Yes. SOCRATES: And if we are good, then we are profitable; for all good 317
