Socrates, considered one of the founders of Western philosophy, was once named the wisest man on earth by the Oracle of Delphi. When Socrates heard that the oracle had made such a comment, he believed that the statement was wrong.
Socrates said: “I know one thing: that I know nothing.”
How can the smartest man on earth know nothing? I heard this paradoxical wisdom for the first time from my school teacher when I was 14 or 15. It made such an impact on me that I used Socrates’ quote as my learning strategy.
