theion

Heidegger's attempts to transform theology into "theiology" and thus to transform a thinking/speaking about God into a thinking/speaking of the divine (theion) point in this direction.

What appeared here, at the center of the Pythagorean tradition in philosophy, is another view of psyche that seems to owe little or nothing to the pan-vitalism or pan-deism (see theion) that is the legacy of the Milesians. The impersonal 'divinity' (theion) has a longer history than the personal, god (theos).

This question inquires into the first cause and highest existent ground of beings. It is the question of the theion, a question that had already arisen at the beginning of metaphysics in Plato and Aristotle; that is to say, arisen from the essence of metaphysics. Because metaphysics, thinking the being as such, is approached by Being but thinks it on the basis of and with reference to beings, metaphysics must therefore say (legein) the theion in the sense of the highest existent ground.
