1 I, 2 | physicists hold, some declaring air to be the first principle,
2 I, 4 | than fire and rarer than air then generate everything
3 I, 4 | which it is not. Water and air are, and are generated "
4 I, 6 | preferable; for fire, earth, air, and water are already involved
5 I, 6 | the next best choice is air, as presenting sensible
6 I, 6 | than the others; and after air, water. All, however, agree
7 II, 1 | simple bodies (earth, fire, air, water)-for we say that
8 II, 1 | assert earth, others fire or air or water or some or all
9 II, 4 | does when he says that the air is not always separated
10 II, 5 | e.g. of health the fresh air or the sun’s heat may be
11 III, 4 | so-called elements-water or air or what is intermediate
12 III, 5 | infinites. (Yet just as part of air is air, so a part of the
13 III, 5 | Yet just as part of air is air, so a part of the infinite
14 III, 5 | which it is an attribute-the air or the even number.~Thus
15 III, 5 | is finite in amount while air is infinite and a given
16 III, 5 | power the same amount of air in any ratio provided it
17 III, 5 | this the infinite, and not air or water, in order that
18 III, 5 | applies equally to all, air, water, or anything else-but
19 III, 5 | our world here, alongside air and fire and earth and water:
20 III, 5 | body, but either water or air or what is intermediate
21 III, 6 | whose essential nature is air or something of the kind.
22 IV, 1 | gone out as from a vessel, air is present. When therefore
23 IV, 1 | another. What now contains air formerly contained water,
24 IV, 1 | turn will be those of the air. But when we come to a point
25 IV, 2 | heavens because you are in the air and it is in the heavens;
26 IV, 2 | heavens; and you are in the air because you are on the earth;
27 IV, 2 | As we pointed out, where air was, water in turn comes
28 IV, 2 | when water is produced from air, the place has been destroyed,
29 IV, 4 | place, because it is in the air, and the air is in the world;
30 IV, 4 | it is in the air, and the air is in the world; and when
31 IV, 4 | when we say it is in the air, we do not mean it is in
32 IV, 4 | is in every part of the air, but that it is in the air
33 IV, 4 | air, but that it is in the air because of the outer surface
34 IV, 4 | the outer surface of the air which surrounds it; for
35 IV, 4 | surrounds it; for if all the air were its place, the place
36 IV, 4 | For when the water and the air change places, all the portions
37 IV, 4 | where they are that the air and the water (or the parts
38 IV, 4 | say so because what was air is now water, in the other
39 IV, 4 | the other because where air formerly was there a is
40 IV, 4 | bodies which are moved. The air, too, which is thought to
41 IV, 5 | in water, and this in the air, and the air in the aether,
42 IV, 5 | this in the air, and the air in the aether, and the aether
43 IV, 5 | moves a part of water or air: so, too, air is related
44 IV, 5 | of water or air: so, too, air is related to water, for
45 IV, 5 | form-water is the matter of air, air as it were the actuality
46 IV, 5 | form-water is the matter of air, air as it were the actuality
47 IV, 5 | for water is potentially air, while air is potentially
48 IV, 5 | is potentially air, while air is potentially water, though
49 IV, 5 | water will be related to air in a way as part to whole.
50 IV, 6 | ingenious demonstration that air is something—by straining
51 IV, 6 | showing the resistance of the air, and by cutting it off in
52 IV, 6 | void (so what is full of air is void). It is not then
53 IV, 6 | not then the existence of air that needs to be proved,
54 IV, 6 | inhales it, from the infinite air. Further it is the void
55 IV, 7 | water is compressed the air within it is squeezed out);
56 IV, 7 | were to be transformed into air.~In general, both the argument
57 IV, 8 | maintain, or because the air that has been pushed pushes
58 IV, 8 | through, as between water, air, and earth, or because,
59 IV, 8 | For let B be water and D air; then by so much as air
60 IV, 8 | air; then by so much as air is thinner and more incorporeal
61 IV, 8 | to the speed, then, that air has to water. Then if air
62 IV, 8 | air has to water. Then if air is twice as thin, the body
63 IV, 8 | substance Z which exceeds air in thickness in the ratio
64 IV, 8 | be displaced; so too in air; but the effect is imperceptible
65 IV, 8 | just as if the water or air had not been displaced by
66 IV, 8 | nowhere in the world. For air is something, though it
67 IV, 9 | bulge, as Xuthus said, or air and water must always change
68 IV, 9 | into equal amounts (e.g. if air has been made out of a cupful
69 IV, 9 | out of an equal amount of air a cupful of water must have
70 IV, 9 | transformation of water into air will always be balanced
71 IV, 9 | equal transformation of air into water (for it is clear
72 IV, 9 | for it is clear that the air produced from water is bulkier
73 IV, 9 | of water produced out of air, so that the entire bulk
74 IV, 9 | This is evident; for when air is produced from water,
75 IV, 9 | water is produced from air in the same way, the change
76 IV, 9 | Similarly, therefore, if air which is large in extent
77 VII, 2 | alteration are adjacent. Thus the air is continuous with that
78 VII, 2 | alteration is continuous with the air. Again, the colour is continuous
79 VII, 2 | respect to the moved is the air. Similarly, in the case
80 VII, 4 | whether applied to water or to air, yet water and air are not
81 VII, 4 | or to air, yet water and air are not commensurable in
82 VII, 4 | two to one), yet water and air are not commensurable in

84 VII, 5 | even such a quantity of the air as it would move if this

86 VIII, 4 | potentially light), and air is actually light, and will

90 VIII, 10| this kind takes place in air and water. Some say that

92 VIII, 10| that different parts of the air are moved one after another):
