'True again.' What is the nature of the movement of the soul?
We must not suppose that we can see and know the soul with our bodily eyes, any more than we can fix them on the midday sun; it will be safer to look at an image only.

'How do you mean ?' Let us find among the ten kinds of motion an image of the motion of the mind.

You remember, as we said, that all things are divided into two classes; and some of them were moved and some at rest.

'Yes.' And of those which were moved, some were moved in the same place, others in more places than one.

'Just so.' The motion which was in one place was circular, like the motion of a spherical body; and such a motion in the same place, and in the same relations, is an excellent image of the motion of mind.
