Discussion of Friedrich Nietsche’s best known work, which he published 1883. Zarathushtra was a prophet who probably lived some 3,000 years ago in the southern part of Turkmenistan near the border with Persia. Nietsche chose the name Zarathustra because of the similarity of his protagenist with the ancient prophet. The historical Zarathushtra, being an independent, critical thinker, argues with his god Ahura Mazda( the great god in old Parsi) in the Gathas fragment, which was discovered in the 18th century. Nietsche was an independent thinker who argued about previous philosophies and about religion. In my judgment none of the following philosophers achieved an equal mode of insight and analysis.
