 1   I,  1 |      science which has to do with nature clearly concerns itself
 2   I,  1 |          of things constituted by nature some are bodies and magnitudes,
 3   I,  1 |     having taken these three from nature as (so to speak) laws of
 4   I,  1 |         but follow the lead which nature gives. Therefore, since "
 5   I,  2 |          2~The question as to the nature of the whole, whether it
 6   I,  2 |        capable of locomotion; for nature, we say, is their principle
 7   I,  2 |          of movement in their own nature, such as fire and earth
 8   I,  2 |          and in virtue of its own nature with a circular movement.
 9   I,  2 |       conclusion that there is in nature some bodily substance other
10   I,  2 |          nevertheless contrary to nature. At any rate the evidence
11   I,  2 |         the superior glory of its nature is proportionate to its
12   I,  3 |          consider their essential nature. Let us then apply the term "
13   I,  3 |          it could move by its own nature either from or towards the
14   I,  3 |           motion to the circular, nature seems justly to have exempted
15   I,  3 |       have some conception of the nature of the gods, and all who
16   I,  4 |          is not worn. But God and nature create nothing that has
17   I,  5 |      those who have written about nature as a whole. So it has been
18   I,  7 |          their figures; but their nature is one, like many pieces
19   I,  8 |          worlds, being similar in nature to ours, must all be composed
20   I,  8 |     refuse to admit the identical nature of the simple bodies in
21   I,  8 |         postulate a difference of nature in the simple bodies according
22   I,  8 |   Philosophy, as well as from the nature of the circular movement,
23   I,  9 |           and products whether of nature or of art we can distinguish
24   I,  9 |       when we state the essential nature of the sphere or circle
25   I,  9 |   whatever is there, is of such a nature as not to occupy any place,
26   I,  10|      arguments appropriate to the nature of the heaven: on the general
27   I,  12|         is by chance, then, is by nature such as to exist at one
28  II,  1 |         divinations of the divine nature. But of this enough for
29  II,  2 |         they are proper to animal nature. For in some animals we
30  II,  3 |           the circular body whose nature it is to move always in
31  II,  4 |         its substance and also by nature primary.~First, let us consider
32  II,  5 |           a probable solution. If nature always follows the best
33  II,  5 |        difficulty. Supposing that nature is ordered in the best way
34  II,  8 |       further, the absurdity that nature has bestowed upon them no
35  II,  8 | appropriate to such movement. For nature leaves nothing to chance,
36  II,  8 |       things so precious. Indeed, nature seems deliberately to have
37  II,  9 |          motion either of animate nature or of constraint. It is
38  II,  9 |       constraint. It is as though nature had foreseen the result,
39  II,  11|           that it is not in their nature to move themselves, and,
40  II,  11|       move themselves, and, since nature is no wanton or random creator,
41  II,  12|           of motions. Thus, then, nature makes matters equal and
42  II,  13|         what it is like and where nature has set it. That centre
43  II,  13|       earth itself! It is not the nature of water, any more than
44  II,  14|       also apparent. If it is the nature of earth, as observation
45  II,  14|      whole so move. For it is the nature of the whole to move to
46  II,  14|          to which it is still its nature to move. Such is the difficulty.
47  II,  14|          call anything that which nature intends it to be, and which

49 III,  1 |          part of the inquiry into nature concerns bodies: for a natural
50 III,  1 |         instances of inquiry into nature. Since, then, we have spoken
51 III,  1 |           to speak as students of nature. There may be things not
52 III,  1 |         inquiry than the study of nature. They, however, had no idea

55 III,  2 |          those of which bodies of nature’s composing are composed,
56 III,  2 |       perceptible things is their nature. And there is also absurdity
57 III,  2 |     infinitely continued. For the nature of things is the nature
58 III,  2 |           nature of things is the nature which most of them possess
59 III,  2 |    constrained or contrary to its nature. We go on to show that there
60 III,  2 |          or lightness. But since "nature" means a source of movement
61 III,  2 |           is always due either to nature or to constraint, movement

64 III,  7 |      product, in the knowledge of nature is the unimpeachable evidence
65 III,  8 |     shapes are not fixed. Indeed, nature itself seems to offer corroboration
66  IV,  1 |          because the inquiry into nature is concerned with movement,
67  IV,  1 |         are things whose constant nature it is to move away from

71  IV,  4 |        heavy one which of its own nature always moves downward, if
