2. And what of lower things? [Why have they not this motion?]
[Their case is very different]: the single thing here is not an all but a part and limited to a given segment of space; that other realm is all, is space, so to speak, and is subject to no hindrance or control, for in itself it is all that is.
And men?
As a self, each is a personal whole, no doubt; but as member of the universe, each is a partial thing.
But if, wherever the circling body be, it possesses the Soul, what need of the circling?
Because everywhere it finds something else besides the Soul [which it desires to possess alone].
The circular movement would be explained, too, if the Soul’s power may be taken as resident at its centre.
Here, however, we must distinguish between a centre in reference to the two different natures, body and Soul.
In body, centre is a point of place; in Soul it is a source, the source of some other nature. The word, which without qualification would mean the midpoint of a spheric mass, may serve in the double reference; and, as in a material mass so in the Soul, there must be a centre, that around which the object, Soul or material mass, revolves.
