Thus Spake Zarathustra) is a philosophical novel by German philosopher Friedrich Nietzsche. The book chronicles the fictitious travels and speeches of Zarathustra. Zarathustra's namesake was the Persian founder of Zoroastrianism, usually known in English as Zoroaster. Nietzsche is clearly portraying a "new" or "different" Zarathustra, one who turns traditional morality on its head. He goes on to characterize "what the name of Zarathustra means in my mouth, the mouth of the first immoralist:" The book embodies a number of innovative poetical and rhetorical methods of expression. It serves as a parallel and supplement to the various philosophical ideas present in Nietzsche's body of work. He has, however, said that "among my writings my Zarathustra stands to my mind by itself." Emphasizing its centrality and its status as his magnum opus. Since many of the book's ideas are also present in his other works, Zarathustra is seen to have served as a precursor to his later philosophical thought. With the book, Nietzsche embraced a distinct aesthetic assiduity. He later reformulated many of his ideas, in Beyond Good and Evil and various other writings that he composed thereafter. He continued to emphasize his philosophical concerns; generally, his intention was to show an alternative to repressive moral codes and to avert "nihilism" in all of its varied forms. While Nietzsche injects myriad ideas into the book, a few recurring themes stand out. The overman (Übermensch), a self-mastered individual who has achieved his full power, is an almost omnipresent idea in Thus Spoke Zarathustra. Man as a race is merely a bridge between animals and the overman. Nietzsche also makes a point that the overman is not an end result for a person, but more the journey toward self-mastery. The eternal recurrence, found elsewhere in Nietzsche's writing, is also mentioned. "Eternal recurrence" is the possibility that all events in one's life will happen again and again, infinitely. The embrace of all of life's horrors and pleasures alike shows a deference and acceptance of fate, or Amor Fati. The love and acceptance of one's path in life is a defining characteristic of the overman. Faced with the knowledge that he would repeat every action that he has taken, an overman would be elated as he has no regrets and loves life. Opting to change any decision or event in one's life would indicate the presence of resentment or fear; contradistinctly the overman is characterized by courage and a Dionysian spirit. The will to power is the fundamental component of human nature. Everything we do is an expression of the will to power. The will to power is a psychological analysis of all human action and is accentuated by self-overcoming and self-enhancement. Contrasted with living for procreation, pleasure, or happiness, the will to power is the summary of all man's struggle against his surrounding environment as well as his reason for living in it.
