The Number of Motion

Time therefore is the number of motion according to prior and posterior and that it is continued. The least number however simply considered is the duad but a certain number is partly the least and partly not as for instance of a line the least number is in multitude two or onebut there is not a least in magnitude for every line is always divisible hence also similarly time for one or two is the least according to number but is not according to magnitude. It is evident why time is not said to be swift and slow but much in view and long and short  for so far as it is continued it is long and short with no end at all.
