Why literature?

This is from an article entitled "Against Reading" in the April 24th issue of The Chronicle of Higher Education. It's a longish piece of which I'm glad I got past the first few paragraphs to this well-said observation:

"To be young is often to know, or to sense, what others have in mind for you and not to like it. But what is harder for a person who has gone unhappily through the first rites of passage into the tribe is to know how to replace the values she's had imposed on her with something better. She's learned a lot of socially sanctioned languages, and still none of them are hers. But are there any that truly might be? Is there something she might be or do in the world that's truly in keeping with the insistent, but often speechless, self that presses forward internally?

This, I think, is where literature can come in — as can all of the other arts and in some measure the sciences, too. By venturing into what Arnold memorably called "the best that has been known and thought," a young person has the chance to discover new vital possibilities. Such a person sees that there are other ways of looking at the world and other ways of being in the world than the ones that she's inherited from her family and culture. She sees, with Emily Dickinson, that a complex, often frayed, often humorous dialogue with God must be at the center of her life; she sees, with Charles Dickens, that humane decency is the highest of human values and understands that her happiness will come from shrewdly serving others; she likes the sound of Blake and — I don't know — forms a better rock band than the ones we've been hearing for the last decade and more; he seconds Samuel Johnson and Edmund Burke and becomes a conservative, in his way twice wiser than NPR-addicted, Prius-proselytizing Mom and Dad.

In short, the student reads and feels that sensation that Emerson describes so well at the beginning of "Self-Reliance": "In every work of genius we recognize our own rejected thoughts; they come back to us with a certain alienated majesty.""
