Book 15: 1812-13: When seeing a dying animal a man feels a sense of horror: substance similar to his own is perishing before his eyes. But when it is a beloved and intimate human being that is dying, besides this horror at the extinction of life there is a severance, a spiritual wound, which like a physical wound is sometimes fatal and sometimes heals, but always aches and shrinks at any external irritating touch.
