Given this point...

Given this point, changes can be divided into two general types: instantaneous and gradual. Another point is that for every kind of gradual change (types seven and thirteen) three subtypes can be considered: one is that in which the earlier parts are like the later parts, such a motion at a constant speed without acceleration; the second subtype is that in which the later parts are more intense and stronger than the earlier parts, such as intensifying motion and speeding up; and the third subtype is that in which the later parts are weaker than the earlier parts as in decelerating motion and slowing down.

However, there is some controversy about this which will be indicated later. The Positions of the Philosophers Regarding the Types…
