I have asked this question all my life. I have sought the answer through my reading and writings, through the music of my youth, through arguments with your grandfather, with your mother. I have searched for answers in nationalist myth, in classrooms, out on the streets, and on other continents. The question is unanswerable, which is not to say futile.
(I know this is an aside... but maybe it isn't.) Just in case anybody needed a definition of "inquiry," these sentences would do just fine. I know it can seem like too much to ask of youth, but I think we can find ways to help them to find the question they have been asking all of their lives, just like Coates's question here: "unanswerable, which is not to say futile." How different that is from finding a "researchable question."
