 Time measures also things that are at rest because they exist in time (221b8–9). The Arabic translation does not insert “incidentally” to restrict “measures” (Ṭabīʻa [1964: 456: 4–5]). In his commentary (LC 192F TC118; MC Wolfson 647), Averroes shows first his concern for things that are eternally in motion like the universe and things that are eternally at rest like the earth: he says that they cannot be measured by time (LC 192L). Therefore, time measures motion and rest; it measures motion essentially and primarily, and it measures rest incidentally and secondarily, i.e., “as it is deprivation of motion” (LC 193L); the solution fits in with Averroes’ way of thinking.
