Query: Which ancient text provides an example of the humanist way of thinking?
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).
