Socrates himself said, ‘One thing only I know, and this is that I know nothing.’ Remember this statement, because it is an admission that is rare, even among philosophers. Moreover, it can be so dangerous to say in public that it can cost you your life. The most subversive people are those who ask questions. Giving answers is not nearly as threatening. Any one question can be more explosive than a thousand answers.
