-Aristotle defines time as a sort of number. It’s any count of the parts of kinesis ordered by things like in front of and behind, stages of development, or relation to the parts of some other motion (a second hand, a pendulum, etc.)
-Making time a number is how A. avoids Zeno’s paradoxes, since time is always actually some unit and never actually a continuously divisible magnitude.
-Time is always many while kinesis is one. An hour can’t mature and a second can’t get to a destination. Both can only repeat.
-Kinesis is one from its goal, fulfillment or specification.
-Calculus or the theory of limits is not a response to Zeno. His theories are critiques of motion and time and approaching a limit is not a motion and takes no time. How long does a derivative take?
-Euclid I.4 is not a motion. How far apart are the triangles? How long does it take?
-Just because you imagine a line moving does not mean that lines move any more than measuring something in a dream makes it just that long.
-Descartes allows two things to be true in dreams: mathematics and the self.
–Motion is continuous because it is infinitely divisible but time is continuous because it has no first or minimum unit.
-Time as such has a unit but not a minimum one while motion as such has no unit at all. This is what A. means when he says that Zeno confuses potential divisions with actual ones. The actual divisions are whatever unit of time one chooses to take and its multiplications, not the potential divisions of motion that allow the time unit to be as small as one pleases.
