SOCRATES:--If, then, you went indoors, and seeing him, did not know him, but thought that he was some one else, would you venture to slay him? ALCIBIADES: Most decidedly not (it seems to me). (These words are omitted in several MSS.) SOCRATES: For you designed to kill, not the first who offered, but Pericles himself? ALCIBIADES: Certainly. SOCRATES: And if you made many attempts, and each time failed to recognize Pericles, you would never attack him? ALCIBIADES: Never. SOCRATES: Well, but if Orestes in like manner had not known his mother, do you think that he would ever have laid hands upon her? ALCIBIADES: No. SOCRATES: He did not intend to slay the first woman he came across, nor any one else's mother, but only his own? ALCIBIADES: True. SOCRATES: Ignorance, then, is better for those who are in such a frame of mind, and have such ideas? ALCIBIADES: Obviously. SOCRATES: You acknowledge that for some persons in certain cases the ignorance of some things is a good and not an evil, as you formerly supposed? ALCIBIADES: I do. SOCRATES: And there is still another case which will also perhaps appear strange to you, if you will consider it? (The reading is here uncertain.) ALCIBIADES: What is that, Socrates? SOCRATES: It may be, in short, that the possession of all the sciences, if unaccompanied by the knowledge of the best, will more often than not injure the possessor. Consider the matter thus:--Must we not, when we intend either to do or say anything, suppose that we know or ought to know that which we propose so confidently to do or say? ALCIBIADES: Yes, in my opinion. SOCRATES: We may take the orators for an example, who from time to time advise us about war and peace, or the building of walls and the construction of harbours, whether they understand the business in hand, or only think that they do. Whatever the city, in a word, does to another city, or in the management of her own affairs, all happens by the counsel of the orators. ALCIBIADES: True. SOCRATES: But now see what follows, if I can (make it clear to you). (Some words appear to have dropped out here.) You would distinguish the wise from the foolish? ALCIBIADES: Yes. SOCRATES: The many are foolish, the few wise? ALCIBIADES: Certainly. SOCRATES: And you use both the terms, 'wise' and 'foolish,' in reference to something? ALCIBIADES: I do. SOCRATES: Would you call a person wise who can give advice, but does not know whether or when it is better to carry out the advice? ALCIBIADES: Decidedly not. SOCRATES: Nor again, I suppose, a person who knows the art of war, but does not know whether it is better to go to war or for how long? ALCIBIADES: No. SOCRATES: Nor, once more, a person who knows how to kill another or to take away his property or to drive him from his native land, but not when it is better to do so or for whom it is better? ALCIBIADES: Certainly not.
