“That a pattering of sounds on the ear should have such moment is a fact calculated to give pause to those philosophers who attempt to explain consciousness by its utility, or who wish to make physical and moral processes march side by side from all eternity. Music is essentially useless, as life is: but both have an ideal extension which lends utility to its conditions. That the way in which idle sounds run together should matter so much is a mystery of the same order as the spirit’s concern to keep a particular body alive, or to propagate its life.”
George Santayana, The Life of Reason: The Phases of Human Progress
