266 the Greeks call ἡγεμονικόν; which must and ought to be the most excellent quality, wherever it is found. That, therefore, in which the prevailing quality of all nature resides must be the most excellent of all things, and most worthy of the power and pre-eminence over all things.

Now, we see that there is nothing in being that is not a part of the universe; and as there are sense and reason in the parts of it, there must therefore be these qualities, and these, too, in a more energetic and powerful degree, in that part in which the predominant quality of the world is found. The world, therefore, must necessarily be possessed of wisdom; and that element, which embraces all things, must excel in perfection of reason. The world, therefore, is a God, and the whole power of the world is contained in that divine element.

The heat also of the world is more pure, clear, and lively, and, consequently, better adapted to move the senses than the heat allotted to us; and it vivifies and preserves all things within the compass of our knowledge.

It is absurd, therefore, to say that the world, which is endued with a perfect, free, pure, spirituous, and active heat, is not sensitive, since by this heat men and beasts are preserved, and move, and think; more especially since this heat of the world is itself the sole principle of agitation, and has no external impulse, but is moved spontaneously; for what can be more powerful than the world, which moves and raises that heat by which it subsists?

XII. For let us listen to Plato, who is regarded as a God among philosophers. He says that there are two sorts of motion, one innate and the other external; and that that which is moved spontaneously is more divine than that which is moved by another power. This self-motion he places in the mind alone, and concludes that the first principle of motion is derived from the mind. Therefore, since all motion arises from the heat of the world, and that heat is not moved by the effect of any external impulse, but of its own accord, it must necessarily be a mind; from whence it follows that the world is animated.

On such reasoning is founded this opinion, that the world is possessed of understanding, because it certainly has more perfections in itself than any other nature; for
