Charmides blushed, and the blush heightened his beauty, for modesty
is becoming in youth; he then said very ingenuously, that he really
could not at once answer, either yes, or no, to the           which
I had asked: For, said he, if I affirm that I am not temperate, that
would be a strange thing for me to say of myself, and also I should
give the lie to Critias, and many others who think as he tells you,
that I am temperate: but, on the other hand, if I say that I am, I
shall have to praise myself, which would be ill manners; and therefore
I do not know how to answer you.
