The obvious truth is that the moment any matter has passed through the human mind it is finally and for ever spoilt for all purposes of science. It has become a thing incurably mysterious and infinite; this mortal has put on immortality. Even what we call our material desires are spiritual, because they are human. Science can analyse a pork-chop, and say how much of it is phosphorous and how much is protein; but science cannot analyse any man’s wish for a pork-chop, and say how much of it is hunger, how much custom, how much nervous fancy, how much a haunting love of the beautiful.
