SOCRATES: Do you see the reason why, or shall I tell you?
ALCIBIADES: Tell me.
SOCRATES: The reason is, that you not only do not know, my friend, but you do not think that you know.
ALCIBIADES: There again; what do you mean?
SOCRATES: Ask yourself; are you in any perplexity about things of which you are ignorant? You know, for example, that you know nothing about the preparation of food.
ALCIBIADES: Very true.
SOCRATES: And do you think and perplex yourself about the preparation of food: or do you leave that to some one who understands the art?
ALCIBIADES: The latter.
SOCRATES: Or if you were on a voyage, would you bewilder yourself by considering whether the rudder is to be drawn inwards or outwards, or do you leave that to the pilot, and do nothing?
ALCIBIADES: It would be the concern of the pilot.
