When any question is asked, the general response is to try and answer it.
Philosophers, for the most part, will try to find out why the question is asked. This is, of course, a very convenient way of avoiding the burden of seeking an answer.
Yet, if you look deeper into the matter, you will find that the question of why any question is being asked is more difficult to answer. So, instead of escaping the burden of seeking an answer to the shallower question, philosophers actually take on the heavier burden of trying to answer the deeper question.
