Who they are

Aristotle investigated nature through systematic philosophical arguments about bodies, motion and the structure of the cosmos. In On the Heavens he reasoned toward one finite universe and distinguished celestial from terrestrial motion. His inclusion records a powerful historical model of reality, including the assumptions from which it was constructed.

His cosmology provides an early conceptual framework against which later astronomical models can be understood.
