Theōria

Theōria (θεωρία) means contemplation, the act of beholding or looking upon — and it is the root of our word theory, though the modern sense has drifted far from the original. The word derives from theōros (θεωρός), a 'spectator', and especially the sacred envoy a city sent to behold the great festivals or to consult an oracle. At its origin, then, theōria is not detached speculation but a reverent witnessing, a journey made in order to see something holy.

Greek philosophy took this beholding inward and upward. Aristotle held that the highest and most god-like human activity is contemplation — the bios theōrētikos, the contemplative life, in which the mind beholds the eternal and necessary truths and is most fully itself; in such activity, he says, we touch something divine. For him the divine itself is contemplation, the Intellect eternally thinking its own thinking.

In Neoplatonism theōria becomes the very engine of reality and of the soul's ascent. Plotinus taught that all things, even nature, are at bottom forms of contemplation, and that each level of reality is constituted by contemplating the level above it. The soul rises by turning from action and the senses to the inner vision of Intellect, and beyond it toward the union with the One — the final beholding in which, paradoxically, seer and seen are no longer two.
