But it was by means of electricity applied to the wheel that the wheel merges once more with animal form. In fact, the wheel is now an obsolete form in the electric-missile age.

Any creature in motion is a wheel in that repetitive form of movement has a cyclic and circular principle in it. Thus the melodies of literate societies are repeatable cycles.
