Whether water or fire be most useful. (2-4)

Now then, is not that the most useful to us, which in all places and always and most of all we stand in need of, — like a piece of household-stuff or a tool, nay, like a friend that is ready at all hours and seasons? But fire is not always useful; for sometimes it is a prejudice to us and we avoid it if we can. But water is useful, winter and summer, to the healthy and sick, night and day; neither indeed is there any time but that a man has need of it. Therefore it is that the dead are called alibantes, as being without moisture (λιβάς) and by that means deprived of life; and man may be without fire, but never

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.
