Title:
Humanism

Context:
Another instance of ancient humanism as an organised system of thought is found in the Gathas of Zarathustra, composed between 1,000 BCE – 600 BCE in Greater Iran. Zarathustra's philosophy in the Gathas lays out a conception of humankind as thinking beings dignified with choice and agency according to the intellect which each receives from Ahura Mazda (God in the form of supreme wisdom). The idea of Ahura Mazda as a non-intervening deistic divine God/Grand Architect of the universe tied with a unique eschatology and ethical system implying that each person is held morally responsible for their choices, made freely in this present life, in the afterlife. The importance placed on thought, action, responsibility, and a non-intervening creator was appealed to by, and inspired a number of, Enlightenment humanist thinkers in Europe such as Voltaire and Montesquieu.
