 Averroes too provided an argument for time’s having no beginning, but now in terms of conceiving time as a circle (Averroes 1991, question III). As was explained above, for Averroes time is a consequence and measure of the circular motion of the heavens and so is itself circular. Now just as any point on a circle is both a beginning and ending of some arc on the circle, so any moment assumed in time must be a beginning and ending of some period of time. Consequently time has no beginning. That it should have no beginning, however, is not in the sense that a straight line has no beginning, but in the sense that no point on a circle can be said to be the beginning of the circle. Although Averroes did not explicitly claim that all events and thing will come around again, his argument does seem to imply such a conclusion.
