Day 28

Rhazes (Abu Bakr al-Razi) (C.864—925)

Absolute time is duration, eternity. It is eternal. It is moving perpetually. Restricted time is that which results from the motion of the spheres and the course of the sun and the stars. ... Absolute place is like a vessel containing bodies. When you eliminate the bodies from thought, the vessel does not vanish. ... but relative place is relative to that which occupies it. And when there is nothing which occupies, there is no place.
