"Perhaps some of you will think I am jesting, but be sure that all that I shall say is true. What has caused my reputation is none other than a certain kind of wisdom. What kind of wisdom? Human wisdom, perhaps. It may be that I really possess this, while those whom I mentioned just now are wise with a wisdom more than human; else I cannot explain it, for I certainly do not possess it, and whoever says I do is lying and speaks to slander me. Do not create a disturbance, gentlemen, even if you think I am boasting, for the story I shall tell does not originate with me, but I will refer you to a trustworthy source. I shall call upon the god at Delphi as witness to the existence and nature of my wisdom, if it be such. You know Chaerephon. He was my friend from youth, and the friend of most of you, as he shared your exile and your return. You surely know the kind of man he was, how impulsive in any course of action. He went to Delphi at one time and ventured to ask the oracle—as I say, gentlemen, do not create a disturbance—he asked if any man was wiser than I, and the Pythian replied that no one was wiser. Chaerephon is dead, but his brother will testify to you about this. [...] For a long time I was at a loss as to his meaning; then I very reluctantly turned to some such investigation as this; I went to one of those reputed wise, thinking that there, if anywhere, I could refute the oracle and say to it: “This man is wiser than I, but you said I was.”Then, when I examined this man— there is no need for me to tell you his name, he was one of our public men—my experience was something like this: I thought that he appeared wise to many people and especially to himself, but he was not. I then tried to show him that he thought himself wise, but that he was not. As a result he came to dislike me, and so did many of the bystanders. So I withdrew and thought to myself:“I am wiser than this man; it is likely that neither of us knows anything worthwhile, but he thinks he knows something when he does not, whereas when I do not know, neither do I think I know; so I am likely to be wiser than he to this small extent, that I do not think I know what I do not know.”After this I approached another man, one of those thought to be wiser than he, and I thought the same thing, and so I came to be disliked both by him and by many others."
