" Socrates, I certainly used to hear, even before meeting you, that you never do anything else than exist in a state of perplexity yourself and put others in a state of perplexity. And now you seem to me to be bewitching me and drugging me and simply subduing me with incantations, so that I come to be full of perplexity. And you seem to me, if it is even appropriate to make something of a joke, to be altogether, both in looks and in other respects, like the flat torpedo fish of the sea. For, indeed, it always makes anyone who approaches and touches it grow numb, and you seem to me now to have done that very sort of thing to me, making me numb. For truly, both in soul and in mouth, I am numb and have nothing with which I can answer you. And yet thousands of times I have made a great many speeches about virtue, and before many people, and done very well, in my own opinion anyway; yet now I’m altogether unable to say what it is. "
