Nothing shocks our moral feelings so deeply as cruelty does. We can forgive every other crime, but not cruelty. The reason for this is that it is the very opposite of compassion.
Arthur SchopenhauerThus also every keen pleasure is an error and an illusion, for no attained wish can give lasting satisfaction.
Arthur Schopenhauerthe brut first knows death when it dies, but man draws consciously nearer to it every hour that he lives; and this makes his life at times a questionable good even to him who has not recognised this character of constant anaihilation in the whole of life.
