 When on trial for impiety, Socrates traced his inquisitiveness to the Oracle at Delphi (Apology 21d in Cooper 1997). Prior to beginning his mission of inquiry, Chaerephon asked the Oracle: “Who is the wisest of men?” The Oracle answered “No one is wiser than Socrates.” This astounded Socrates because he believed he knew nothing. Whereas a less pious philosopher might have questioned the reliability of the Delphic Oracle, Socrates followed the general practice of treating the Oracle as infallible. The only cogitation appropriate to an infallible answer is interpretation. Accordingly, Socrates resolved his puzzlement by inferring that his wisdom lay in recognizing his own ignorance. While others may know nothing, Socrates knows that he knows nothing.
