From hence we may conclude that, as all parts of the world are sustained by heat, the world itself also has such a great length of time subsisted from the same cause; and so much the more, because we ought to understand that that hot and fiery principle is so diffused over universal nature that there is contained in it a power and cause of generation and procreation, from which all animate beings, and all those creatures of the vegetable world, the roots of which are contained in the earth, must inevitably derive their origin and their increase.

It is nature, consequently, that continues and preserves the world, and that, too, a nature which is not destitute of sense and reason; for in every essence that is not simple, but composed of several parts, there must be some predominant quality--as, for instance, the mind in man, and in beasts something resembling it, from which arise all the appetites and desires for anything.

As for trees, and all the vegetable produce of the earth, it is thought to be in their roots.

I call that the predominant quality,[122] which the Greeks call [Greek: hegemonikon]; 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.
