“Droll thing life is—that mysterious arrangement of merciless logic for a futile purpose.”
Art is a playful, semi-logical arrangement for an arbitrary purpose. As such it has something to say about the drollery of life.
“The most you can hope from it is some knowledge of yourself—that comes too late—a crop of unextinguishable regrets.”
The best one can hope for from a life in art is a better ability to make it. If one can sustain that till the end, one should have no reason for regret.
