At the end of his account, Aristotle raises a puzzle about whether or not there could be time if there were no ensouled beings. It is argued that his answer to this puzzle is that time depends upon the soul in a way in which change does not. Aristotle puts this by saying that if there were no souls, there could not be time, but there might perhaps be change. This chapter explains why Aristotle’s definition of time leads him to this conclusion. It contends that he views time as essentially countable, and because of this, could not exist in the absence of beings able to count. Moreover, Aristotle’s view implies, that time is not just essentially countable but also essentially counted. Because of the way in which time is a number, it can only be countable if it is in fact counted.
