An excessively humanistic book for free thinkers: the second book, by Friedrich Nietzsche

The book discusses the topic of metaphysics, and tried to interpret it and clarify its sources, and elevated the status of natural sciences in return, as well as presented the concept of good and evil from the Christian perspective, and also denied any role for personal genius or divine revelation in artistic creativity, and briefly touched on the idea of the higher human being. It contains sad gestures that only a few could grasp, through which he expressed deep loneliness and that deprivation he experienced throughout all his transitional years. This book will require you great courage to complete, understand, and read with complete impartiality and neutrality, and to know whether many restrictions have been imposed on humans to rid themselves of animalistic behaviors?? This is what we will learn and more in my books. The number of pages is 400.
