Aristotle denied that time was an entity or thing that could exist independently of objects or things--in this respect, his theory is quite modern. He recognized the relationship of time and motion and consequently defines time as the measure or number of a continuous motion taken without qualification. In this paper I reconstruct Aristotle's theory of time using entropy as the 'continuous motion taken without qualification' and note that this helps to explain several passages in the Physics that seem quite (...) obscure otherwise, but in the final analysis an entropic interpretation cannot rescue his theory from certain shortcomings.
