Zoroastrianism

The teachings of Zarathustra (Zoroaster) appeared in Persia at some point during the period between 1000-588 BCE. [1] 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. [1] 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 (humata), good words (hukhata), and good deeds (hvarshatra).

Zarathustra was known as a sage, magician and miracle-worker in post-Classical Western culture, though almost nothing was known of his ideas until the late eighteenth century. By this time his name was associated with lost ancient wisdom and was appropriated by Freemasons and other groups who claimed access to such knowledge. He appears in Mozart's opera "Die Zauberflöte" under the variant name "Sarastro", who represents moral order in opposition to the "Queen of the Night". Enlightenment writers such as Voltaire promoted research into Zoroastrianism in the belief that it was a form of rational Deism, preferable to Christianity.

In 2005, the Oxford Dictionary of Philosophy ranked Zarathustra number two in the chronology of philosophical events. Zarathustra's impact lingers today due in part to the system of rational ethics he founded called Mazda-Yasna. The word Mazda-Yasna is avestan and is translated as "Worship of Wisdom" in English.

Throughout Iranian history, due to Greek and Arabic influence, a wide spectrum of schools of thoughts showed a variety of views on philosophical questions extending from Old Iranian and Zoroastrian traditions, to schools appearing in the late pre-Islamic era, to various Islamic schools. Iranian philosophy after the Arab invasion of Persia is characterized by different interactions with the Old Iranian philosophy with Greek and Islamic philosophy. The Illumination School and the Transcendent Philosophy are regarded as two of the main philosophical traditions of that era in Persia.
