"We do not know — neither the sophists, nor the orators, nor the artists, nor I— what the True, the Good, and the Beautiful are. But there is this difference between us: although these people know nothing, they all believe they know something; whereas, I, if I know nothing, at least have no doubts about it. As a result, all this superiority in wisdom which the oracle has attributed to me reduces itself to the single point that I am strongly convinced that I am ignorant of what I do not know."
