Persian literature in Western culture its narrative. Nietzsche, a radical opposer of Greek Metaphysical thought, was the author of the book "Thus Spoke Zarathustra", referring to the ancient Persian prophet Zoroaster, as the prophet of his philosophy. Nietzsche held very high interest and respect for Persians. For example, where he speaks about the Persian notion of history and "cyclical Eternal Time", he writes: "I must pay tribute to Zarathustra, a Persian, for Persians were the first who thought of history in its full entirety." and further adds: ""It was much more fortunate if Persians became masters (Herr) of the Greeks, than the very Romans." But
Iranian philosophy of Zarathustra (Zoroaster) appeared in Persia at some point during the period 1700-1800 BCE. His wisdom became the basis of the religion Zoroastrianism, and generally influenced the development of the Iranian branch of Indo-Iranian philosophy. Zarathustra was the first who treated the problem of evil in philosophical terms. He is also believed to be one of the oldest monotheists in the history of religion. He espoused an ethical philosophy based on the primacy of "good thoughts (andiše-e-nik), good words (goftâr-e-nik), and good deeds (kerdâr-e-nik)." The works of Zoroaster and Zoroastrianism had a significant influence on Greek philosophy and Roman philosophy.
