The Oracle at Delphi declared

The Oracle at Delphi declared Socrates the most wise man on the earth. A few people rushed to Socrates and they told him, "Be pleased, rejoice: the Oracle at Delphi has declared you the wisest man in the world."Socrates said, "That is all nonsense. I know only one thing: that I know nothing."The people were puzzled and confused. They went back to the temple, they told the Oracle, "You say that Socrates is the wisest man in the world, but he himself denies it. On the contrary, he says he is utterly ignorant. He says he knows only one thing: that he knows nothing."The Oracle laughed and said, "That's why I have declared him the wisest man in the world, the greatest wise man in the world. That's why -- precisely because he knows that he is ignorant."
