- Brad Weslake (2006). Time. In Martin Cohen (ed.), Essentials of Philosophy and Ethics. Hodder Arnold.Attempts to characterise time seem to throw up paradox at every turn. Some of the most famous of the paradoxes are also the oldest—those due to Aristotle (384–322 BC) and Zeno (b. c. 488 BC), as described in Aristotle’s Physics. For example, Zeno argued that in order to traverse any distance, one must always first traverse half that distance; but since this half is itself a distance to be traversed, one must in turn first traverse half of the half, and so on ad infinitum. Since it is impossible to traverse an infinite number of distances in a finite time, all motion must be impossible—indeed, incoherent. A similar argument can be used to show that a line cannot be composed of a set of points, a problem which was only satisfactorily resolved with the development of the modern mathematics of infinity. A central question for the philosophy of time, then, becomes whether (and how) the mathematics of infinity applies to time.

An example of the second situation is the most famous of the paradoxes of Zeno, the Greek philosopher who lived during the Golden Age of Greece on the island of Elea. Zeno proposed the following "thought experiment". Achilles, a young athlete, runs a race with a tortoise. Achilles can run exactly twice as fast as the tortoise, so to make it fair he gives the tortoise a head start of exactly half the distance from the starting line to the finish (...)

We explore the better known paradoxes of Zeno including modern variants based on infinite processes, from the point of view of standard, classical analysis, from which there is still much to learn (especially concerning the paradox of division), and then from the viewpoints of non-standard and non-classical analysis (the logic of the latter being intuitionist).The standard, classical or Cantorian notion of the continuum, modeled on the real number line, is well known, as is the definition of motion as the time (...)

Extending on an earlier paper [Found. Phys. Ltt., 16(4) 343–355, (2003)], it is argued that instants of time and the instantaneous (including instantaneous relative position) do not actually exist. This conclusion, one which is also argued to represent the correct solution to Zeno’s motion paradoxes, has several implications for modern physics and for our philosophical view of time, including that time and space cannot be quantized; that contrary to common interpretation, motion and change are compatible with the “block” universe and (...)
Aristotle begins his famous discussion of time in Book Δ of The Physics by asking whether time belongs to “the things that exist.” In this paper I argue that Aristotle’s apparently ambiguous answer to this question holds one of the keys to clarifying contemporary philosophy of time. First, I argue that the metaphysical and meta-philosophical presuppositions underlying most philosophy of time are deeply flawed. Second, that Aristotle provides us with a much more plausible alternative set of presuppositions about the nature (...)
