The Motion of Motion

A motion of this kind is produced in air and in water which some assert to be an anti-parastasis but it is impossible to solve in any other way the subjects of doubt. One certain thing appears to be continually moved by what therefore for it is not moved by itself. The one will adhere to the other and be divided hence that which moves if it is one either moves being moved or being immovable. This motion is equable either alone or in the most imminent degree from the mover has not any.
