But why do I so meanly confine my discourse to the nature of men, seeing there are many, nay, infinite sorts of creatures? The race of man is almost the only one that knows the use of fire; the others live and feed without fire. Indeed, beasts, birds, and creeping things live upon roots, fruits, and raw flesh, without fire; but without water neither fish nor fowl nor land animals can subsist. For all beasts that feed upon flesh, of which there are some (as Aristotle reports) that never drink, nevertheless support life and being merely by moisture. So that of necessity that must be most profitable without which no sort of life can subsist or endure.

Let us therefore make a step from animals that eat to things that we ourselves make use of, such are plants and fruits; of which some are altogether void of heat, others enjoy it but imperfectly and obscurely. But moisture causes all things to germinate, increase, and bring forth. Why should I stand to reckon up wine and oil, milk and honey, and whatever else we reap and bring forth and see before our eyes, when wheat itself, which is looked upon as a dry nourishment, grows by alteration, putrefaction, and corruption of the moist matter?

Then again, that is most useful which is no way detrimental. Now fire easily becomes most pernicious, but the nature of water is never prejudicial. In the next place, that is most useful which affords the benefit which it brings with least expense, and without any preparation. But the benefit of fire requires cost and materials, and therefore the rich make more use of it than the poor, and princes than private persons; but water has that kindness for mankind, that it freely offers itself to all alike, a benefit perfect in itself, indigent of nothing, and wanting neither tools nor implements.
