On the Genealogy of Morality, the classic three essay treatise of Friedrich Nietzsche, is considered by scholars to be one of the author's philosophic masterworks. This astounding work represents the maturity of Nietzsche's ideas, and consists of three distinct essays. In each, Nietzsche isolates and expands upon ideas he expressed in Beyond Good and Evil. Nietzsche juxtaposes ideas of weakness and strength, and notions of human preconception as generated over millenia of hierarchy inclusive of slavery, to demonstrate an evolution of ideas beyond traditional duality. This text controversially introduces the 'blond beast' - a a forebear for Nietzsche's posthumous association with Nazism and racial superiority. Nietzsche demonstrates how people with allegiance to ascetic ideals gained traction in society. He proceeds to discount science as an opposing influence, together with historians and idle thinkers, advocating for criticism of what is accepted as truth, and a replacement for flawed definitions.
