Moreover, that which by augmentation loses its benefit is of least use. Such is fire, which like a devouring beast ravages all before it, useful rather by art and skilful moderation, than of its own nature. But from water there is nothing to be feared. Furthermore, that is most useful which may be joined with another. But fire will not admit of water, neither is it any way profitable by conjunction with it. But water becomes profitable by joining with fire; and therefore hot waters are wholesome, and sensibly cure several diseases. Neither shall you ever find moist fire; but water both cold and hot is profitable for the body of man. Then again, there being four elements, water produces a fifth out of itself, which is the sea, no less beneficial than the rest, as well for commerce as for many other things. So that it may be said, this element united and perfected our manner of living, which before was wild and unsociable, correcting it by mutual assistance, and creating community of friendship by reciprocal exchanges of one good turn for another. And as Heraclitus said, If there were no sun, it would be perpetual night; so may we say, If there were no sea, man would be the most savage and shameless of all creature. But the sea brought the vine from India into Greece, and out of Greece transmitted the use of corn to foreign parts; from Phoenicia translated the knowledge of letters, the memorials that prevent oblivion; furnished the world with wine and fruit, and prevented the greatest part of mankind from being illiterate and void of education. How is it possible then but that water should be the most useful, when it thus furnishes us with an entirely new element? 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 preserves it in its proper substance, as well water itself as all other things; so that when fire leaves it, water will stink, and it may be said that the want of fire is the death and destruction of water. And thus we find in regard to pools and all manner of standing waters, and such as are settled in pits and holes without issue, what an offensive and dead stench they send forth, and all for want of motion; for this kindles and preserves heat in all things, and more especially in running waters and swift streams, which being thus agitated and enlivened by heat, we commonly say such waters live. Why then should not that be accounted the most useful of the two, that affords to the other the cause of its being, as fire does to water? Moreover, that is the most useful, of which if an animal be wholly deprived, it must perish; for it is evident, that anything without which an animal cannot live affords the reason and cause why it exists. There is moisture also in things after they are dead, nor are they altogether dried up; for otherwise moist bodies would never putrefy; since putrefaction is the alteration of dry into moist, or rather the corruption of moisture in flesh. Neither is death any other than an absolute defect and want of heat, and therefore dead carcasses are the coldest of all; so that if you do but touch them with a razor, they will blunt the edge of it through excess of coldness. Also in living creatures, those parts that least partake of heat are most insensible, as the bones and hair, and those parts which are most distant from the heart. Nay, to some of the most important things the absence of fire and the presence of water are destructive. For plants and fruits are not produced by moisture, but by the warmth of the moisture; and cold waters are most certainly either less productive, or altogether barren. For if water were fruitful in itself, it would always, and that spontaneously too, bear fruit. But the contrary is apparent, and it is rather baneful to generation. 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.
