'To be sure.' In the next place, we acknowledge that the soul is the cause of good and evil, just and unjust, if we suppose her to be the cause of all things?
'Certainly.' And the soul which orders all things must also order the heavens?
'Of course.' One soul or more?
More; for less than two are inconceivable, one good, the other evil.

'Most true.' The soul directs all things by her movements, which we call will, consideration, attention, deliberation, opinion true and false, joy, sorrow, courage, fear, hatred, love, and similar affections.
These are the primary movements, and they receive the secondary movements of bodies, and guide all things to increase and diminution, separation and union, and to all the qualities which accompany them--cold, hot, heavy, light, hard, soft, white, black, sweet, bitter; these and other such qualities the soul, herself a goddess, uses, when truly receiving the divine mind she leads all things rightly to their happiness; but under the impulse of folly she works out an opposite result.

For the controller of heaven and earth and the circle of the world is either the wise and good soul, or the foolish and vicious soul, working in them.

'What do you mean ?' If we say that the whole course and motion of heaven and earth is in accordance with the workings and reasonings of mind, clearly the best soul must have the care of the heaven, and guide it along that better way.

'True.' But if the heavens move wildly and disorderly, then they must be under the guidance of the evil soul.
