Student: "Why do you always answer a question with a question?"
Teacher: "What's wrong with a question?" Indeed! Answer that student because it is hellish complex.
Socrates, as Plato records him, asked questions of students as a means of eliciting thought rather than making didactic statements. It may have been slow and painful and often seemed silly, but it allowed thinking for oneself. The students answer may well lead to a further question in which Socrates often feigned ignorance.
Have we worshiped the accumulation of fact that trumps question and thought, and will question and thought sometimes expose the nakedness of "known" fact? I had two teachers in my lifetime that took the time to employ Socratic methods. They were confusing, exasperating, exposed our ignorance, but were never arbitrary, in thrall of unquestioned facts or spent all of the time thinking inside the box. It took me fifty years to realize it was no joke to question all : there is nothing wrong with a question; and it still is remarkably easy to be wrong.
