 By decadence, Nietzsche is referring to a fading of life, vitality and an embrace of weakness.In Nietzsche's view, if one is to accept a non-sensory, unchanging world as superior and our sensory world as inferior, then one is adopting a hate of nature and thus a hate of the sensory world – the world of the living.Nietzsche postulates that only one who is weak, sickly or ignoble would subscribe to such a belief.
