The animal lacks both anxiety and hope because its consciousness is restricted to what is clearly evident and thus to the present moment: the animal is the present incarnate.
Arthur SchopenhauerIf children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence, or at any rate not take it upon himself to impose that burden upon it in cold blood?
Arthur Schopenhauer
