 1   I,  3 |        using the words "heavy" and "light", sufficiently, at least,
 2   I,  3 |            towards the centre, and "light" to that which moves naturally
 3   I,  3 |            for things are heavy and light relatively to one another;
 4   I,  3 |      another; air, for instance, is light relatively to water, and
 5   I,  3 |      relatively to water, and water light relatively to earth. The
 6   I,  7 |             also be examined in the light of more general considerations
 7   I,  7 |         body is, strictly speaking, light: and if lightness be universal,
 8  II,  7 |            situated. The warmth and light which proceed from them
 9  II,  13|        determines the heavy and the light. Rather that movement caused
10  II,  13|          the pre-existent heavy and light things to go to the middle
11  II,  13|          the whirl began, heavy and light existed; and what can have
12  II,  13|             by these that heavy and light are determined.~It is to
13  II,  14|           whole. For fire and other light things move to the extremity
14 III,  1 |        heavier than something and a light thing lighter than something,
15 III,  1 |         need not be itself heavy or light, just as a large thing is
16 III,  1 |             dense body, and what is light rare. Dense differs from
17 III,  1 |         then, if it may be heavy or light, may be dense or rare. But
18 III,  1 |          some of the planes will be light and others heavy (which

20 III,  2 |          the force. For air is both light and heavy, and thus qua
21 III,  2 |             and heavy, and thus qua light produces upward motion,
22 III,  2 |          that all bodies are either light or heavy, and (2) how unnatural
23  IV,  1 |     consider the terms "heavy" and "light". We must ask what the bodies
24  IV,  1 |            we call things heavy and light because they have the power
25  IV,  1 |             b) a relative heavy and light. Of two heavy things, such
26  IV,  1 |          that the one is relatively light, the other relatively heavy.
27  IV,  1 |            the heavy is or what the light is, but only the relative
28  IV,  1 |        centre below.) By absolutely light, then, we mean that which
29  IV,  1 |            By lighter or relatively light we mean that one, of two
30  IV,  2 |             the most part spoken of light and heavy things only in
31  IV,  2 |        smaller number is relatively light. As a larger quantity of
32  IV,  2 |            the absolutely heavy and light. The facts are that fire
33  IV,  2 |             are that fire is always light and moves upward, while

36  IV,  2 |           case a body is relatively light when it contains a relatively
37  IV,  2 |           to analyse the notions of light and heavy at all; and those
38  IV,  2 |            are absolutely heavy and light, or in other words why some
39  IV,  2 |         lighter than the absolutely light, which nevertheless moves
40  IV,  2 |            so, since the absolutely light is always lighter than bodies
41  IV,  2 |        which is lighter need not be light, because in common speech
42  IV,  2 |            between heavy things and light. There is also an absurdity
43  IV,  2 |           composite bodies are some light and some heavy; they had
44  IV,  2 |           two things are themselves light and heavy respectively,
45  IV,  2 |          can be absolutely heavy or light: and if there is one matter
46  IV,  2 | intermediate between the absolutely light and heavy when compared
47  IV,  2 |         there is nothing absolutely light and nothing which moves

50  IV,  3 |        quantity: and so in place, a light thing goes upward, a heavy

53  IV,  3 |            into being out of water, light out of heavy, it goes to
54  IV,  3 |        upper place. It is forthwith light: becoming is at an end,
55  IV,  4 |         things, from the absolutely light, which is that which rises
56  IV,  4 |           the generic character of "light" and "heavy", in order to
57  IV,  4 |           them is absolutely either light or heavy. Both are lighter
58  IV,  4 |          other bodies are severally light and heavy, and evidently
59  IV,  4 |            bodies will be heavy and light respectively. Therefore
60  IV,  4 |           body which is regarded as light in one place is regarded
61  IV,  4 |         that there is an absolutely light and an absolutely heavy
62  IV,  4 |             body. And by absolutely light I mean one which of its

64  IV,  4 |             away from which that of light things is directed, is manifest
65  IV,  4 |            the duality of heavy and light in the spatial duality centre
