Abstract I have had cause to refer to continuity on numerous occasions throughout the preceding chapters; it is now time to tum the focus of our attention on to this topic. Continuity was an important topic in ancient Greek philosophy, and Aristotle in particular had a great deal to say about it; see White 1992 for a detailed discussion. The distinction between the continuous and the discrete can be applied to any of our key notions of space, time, matter, and change.
