2. QUANTITY.

4. The Aristotelians call quantity first "number," then "continuous size," "space," and "time."[248] To these concepts they apply the other kinds of quantity; as for instance, they say that movement is a quantity measured by time.[249] It might also be said reciprocally, that time receives its continuity from movement.
