Nietzsche has serious flaws. One is that he is abusive – he’s an intellectual bully which killed his morality and led to him being (rightfully) claimed by the full spectrum of ideologies, including Nazism. Probably the most serious flaw in his philosophy is that it’s entirely personalized – he focuses on psychology, linguistics, and psychohistory. The complete absence of any structural analysis (analysis of the state, for example) meant he ultimately is just writing bourgeois and pro-status quo nonsense. Nietzsche is the last of the individualists – no meaningful philosophy can possibly be derived in modern times absent structural analysis.
Nietzsche is utterly naive, and believes in the triumph or failure of the individual will. He offers a romantic vision for the Libertarian Right, those people who have no attachment to reality.
Orwell killed Nietzsche not only because of his profound understanding of the meaninglessness of the individual but because of his destruction of Nietzsche’s romanticization of schizophrenia. For Nietzsche, schizophrenia was a sign of strength, of the individual fighting himself (after all, what does not kill me only makes me stronger). For Orwell, schizophrenia was a sign of weakness, a fundamental break from access to objective reality (Nietzsche denies objective reality) and a kind of self-serving departure from the world.
Nietzsche is not only himself immature but he has left a devastated world in his wake – a world where adults have the minds and aspirations of children, a world of “parallel worlds”, “inner worlds”, and “trips to the other side”, a world where debate is impossible because culture no longer believes in the objective reality that makes debate meaningful. “To each his own”, “you believe what you want to and I’ll beileve what I want to” are derived from Nietzsche.
Nietzsche is a terrible error, and the world may never recover. If it does it will find other philosophers, other ways to follow.
Nietzsche is dead.
