Art serves a purpose. It expands our horizons, frees our minds, and opens us up to new experiences. It opens the imagination. All these great discoveries of our time - without the desire to reach beyond our boundaries, we would be forever stagnant. The folly is in closing one’s eyes and not recognizing it.
I think imagination is at the heart of everything we do. Scientific discoveries couldn't have happened without imagination. Art, music, and literature couldn't exist without imagination. And so anything that strengthens imagination, and reading certainly does that, can help us for the rest of our lives.
