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]
