“…it is central to the rest of this course that you fully understand the difference between a sophist and a philosopher. [Sophists are] self-opinionated know-it-alls who are satisfied with what little they know, or who boast of knowing a whole lot about subjects they haven’t the faintest notion of. […] A real philosopher…knows that in reality he knows very little. That is why he constantly strives to achieve true insight. […] A philosopher is therefore someone who recognizes that there is still a lot he does not understand, and is troubled by it. In that sense, he is still wiser than all those who brag about their knowledge of things they know nothing about. […] Socrates himself said, “One thing only I know, and that is that I know nothing.” […]
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.”
