Nietzsche taught nihilism. He rejects radically the values. Nihilism is not an individual experience or a philosophical doctrine, nor is it a fatal light cast over human nature eternally vowed to nothingness. When the authory of old values has collapsed, this new authorization means that it is permitted to know all, that there is no lonqer a limit to man's activity. Nietzsche saw with striking force that since nihilism is the possibility of all going beyond, it is the horizon for every particular science as well as for the maintenance of scientific development as such.
Science can only be nihilistic.
Up to that point this nothingness was hidden behind various representations of the ideal and various fictions that Nihilism, their proper counterpart, now expatiates. The sensible having been deprecited and the supersensible ceasing to be of value,the essential mctaphysical difference between truth and illusion, ends up rejected. Nihilism is in some fashion always present, always at work, before, during, and after the moment of its violent explosion. Nietzsche, also argues Christianity. Original Christianity taught man not conform to the state and even to seperate himself from his family for the sake of the spirit.
