Aristotle’s mind-dependence theory of time is considerably more than an eccentric afterthought formulated in a short passage, as many believe; rather, it is firmly anchored in Physics IV, especially in Ch. 11. A number of formulations that may seem purely epistemic or propaedeutic in nature do in fact have ontological significance, pointing to the fact that time’s existence hinges crucially on our capacity to perceive change. Aristotle seems to be echoed in crucial respects by contemporary theories of time, notably by A. Grünbaum’s.
