MOVEMENT AS A FORM OF POWER.
Let us, indeed, suppose, that something which formerly was a potentiality succeeds in assuming a form, as "potentiality that becomes a statue," or that passes to actualization, as a man's walk.[421] In the case where the metal becomes a statue, this passage is a movement; in the case of the walking, the walk itself is a movement, like the dance, with one who is capable of it. In the movement of the first kind, where the metal passes into the condition of being a statue, there is the production of another form which is realized by the movement.[422] The movement of the second kind, the dance, is a simple form of the potentiality, and, when it has ceased, leaves nothing that subsists after it.[423]
