This is the crux of the moral pessimists: if they really wanted to promote their neighbor's redemption, then they would have to resolve themselves to spoiling existence for him, and thus to being his misfortune; out of pity, they would have to--become evil!
Friedrich NietzscheHope, in its stronger forms, is a great deal more powerful stimulans to life than any sort of realized joy can ever be. Man must be sustained in suffering by a hope so high that no conflict with actuality can dash it - so high, indeed, that no fulfilment can satisfy it: a hope reaching out beyond this world.
Friedrich Nietzsche
