Whether water or fire be most useful. (8-10)

Or can any man speak as follows in defence of the contrary? We say then that God, as a master workman, had before him the four elements, to complete the fabric of the universe; and these again were different one from another. But earth and water were placed at the foundation, like matter, to be formed and fashioned, participating of form and order and of power to procreate and bring forth, so far as they are assisted by air and fire, — the great artificers that mould them into various shapes, — and lying dead till roused by them to act and generate. Of these two latter, fire is the ruling agent. This is manifest by induction. For earth without warmth and heat is altogether barren and unfruitful; but fire, by virtue of its rousing and inflaming quality, renders it diffusive, and swells it into generation. Nor can any man find out any other cause why rocks and the dry tops of mountains are not productive, but because they participate either nothing at all or very little of fire.

Then generally for water, it is so far from being sufficient of itself for the generation and preservation of other things, that it is itself destroyed for want of fire. But fire is that which upholds every thing in its proper being, and

Let us begin anew. As to the use of fire, considered as fire, we have no need of water. Rather the contrary is to be made out; for water extinguishes fire. And as for water, there is no use to be made of it in most things without fire. For water heated becomes more usefill, whereas otherwise it is prejudicial. So that, of the two, that is to be accounted best which is profitable of itself without the assistance of another. Besides, water is beneficial only to the feeling, when you either wash with it or touch it; but fire is profitable to all the senses, being not only felt, but also seen at a distance; so that you may add this to the rest of the virtues of it, that its uses are manifold.
