  1   I,  2 |       course, it may be brought to move with the motion of something
  2   I,  2 |           itself, but it cannot so move naturally, since there is
  3   I,  2 |          body which is ordained to move with a natural circular
  4   I,  3 |          bottom of all things that move downward, and the lightest
  5   I,  3 |   naturally nor unnaturally can it move either towards or away from
  6   I,  3 |            one of the bodies which move in this way. Suppose, then,
  7   I,  3 |           would mean that it could move by its own nature either
  8   I,  3 |            that it cannot possibly move in the way of locomotion
  9   I,  3 |   naturally nor unnaturally can it move with any other motion but
 10   I,  4 |           be ineffective: for both move to the same point, because
 11   I,  5 |           That the infinite cannot move may also be shown as follows.
 12   I,  5 |      unmoved, except that, if both move, they pass clear of one
 13   I,  5 |     movement to be slow where both move and much faster where one
 14   I,  5 |      infinite. For the infinite to move at all is thus absolutely
 15   I,  6 |  determinate. But the bodies which move up and down may be in it,
 16   I,  6 |          great as the finite, will move accordingly, but being,
 17   I,  6 |           other hand, compelled to move in a time inversely proportionate
 18   I,  6 |           to its greatness, cannot move at all. The time should
 19   I,  6 |            weight must necessarily move a certain finite distance
 20   I,  7 |     impossible for the infinite to move in a circle. This, indeed,
 21   I,  7 |           that the infinite should move at all. If it did, it would
 22   I,  7 |           all. If it did, it would move either naturally or by constraint:
 23   I,  7 |           itself, to which it will move. But that is impossible.~
 24   I,  7 |          time, in that nothing can move another or be moved by it.
 25   I,  7 |        time in which infinites can move one another. Is their time
 26   I,  7 |           cannot, on the one hand, move in a circle. For there is
 27   I,  7 |         Nor again can the infinite move in a straight line. For
 28   I,  7 |           moves naturally can also move unnaturally, there will
 29   I,  7 |           impossible. A thing must move either naturally or unnaturally,
 30   I,  8 |            Now all things rest and move naturally and by constraint.
 31   I,  8 |             one of the bodies will move naturally away from the
 32   I,  8 |             then, in another world move naturally also to our centre
 33   I,  8 |            must, in its own world, move upwards, and fire to the
 34   I,  8 |            earth of our world must move naturally away from the
 35   I,  8 |           since the fact that they move is quite evident. Are we
 36   I,  8 |            to which earth and fire move naturally. For in general
 37   I,  8 |          Thus, too, fire and earth move not to infinity but to opposite
 38   I,  8 |          makes one of these bodies move up and the other down; nor
 39   I,  9 |           else stronger than it to move it-since that would mean
 40   I,  9 |         since everything ceases to move when it comes to its proper
 41   I,  11|        when we speak of a power to move or to lift weights, we refer
 42  II,  2 |            originates. Some do not move at all, some move, but not
 43  II,  2 |           do not move at all, some move, but not indifferently in
 44  II,  2 |          even if it never began to move, yet it must possess a principle
 45  II,  2 |       which it would have begun to move if it had begun, and from
 46  II,  2 |           begin from the right and move round to the right, the
 47  II,  3 |         body whose nature it is to move always in a circle. Why,
 48  II,  5 |       mentioned. For it is best to move with a movement simple and
 49  II,  7 |            missiles, which as they move are themselves fired so
 50  II,  7 |        stars are neither fiery nor move in fire, enough has been
 51  II,  8 |          the stars and the circles move with the same speed, i.e.
 52  II,  8 |         the stars themselves which move. For it will follow that
 53  II,  8 |            that the circles should move, while the stars are at
 54  II,  8 |          the stars are at rest and move with the circles to which
 55  II,  8 |     therefore, the heavens have to move in one lace, and the stars
 56  II,  8 |          stars are not required to move themselves forward, it is
 57  II,  9 |      follows that none of them can move with the motion either of
 58  II,  11|          is not in their nature to move themselves, and, since nature
 59  II,  12|            is nearest to it should move with the fewest movements,
 60  II,  12|         single first motion has to move many of the divine bodies,
 61  II,  12|         the numerous other motions move only one each, since each
 62  II,  12| characteristics of the stars which move with a circular motion,
 63  II,  13|         even the wind can scarcely move them because of their power
 64  II,  13|          and heavier bodies always move to the centre of the whirl.
 65  II,  13|       motion, where will the earth move to then? Its movement to
 66  II,  13|            now do all heavy bodies move to the earth. For the whirl
 67  II,  13|          us. Why, again, does fire move upward? Not, surely, because
 68  II,  13|            is naturally such as to move in a certain direction,
 69  II,  13|        every extreme point; and to move in contrary directions at
 70  II,  13|           remaining there, it will move, only not as a mass but
 71  II,  13|    extremity. Nevertheless it will move, as in fact it always does
 72  II,  13|          as in fact it always does move when nothing stops it, away
 73  II,  13|   extremity. It will not, however, move in a mass to a single point
 74  II,  14|      observed to be passed, and to move with more than one motion.
 75  II,  14|             then, also, whether it move about the centre or as stationary
 76  II,  14|            at it, must necessarily move with two motions. But if
 77  II,  14|       earth and other heavy things move to. Is this their goal because
 78  II,  14|        fire and other light things move to the extremity of the
 79  II,  14|          is the same. Thus they do move to the centre of the earth,
 80  II,  14|            that the earth does not move and does not lie elsewhere
 81  II,  14|           as observation shows, to move from any point to the centre,
 82  II,  14|            of fire contrariwise to move from the centre to the extremity,
 83  II,  14|            portion of earth should move away from the centre except
 84  II,  14|            no portion of earth can move away from the centre, obviously
 85  II,  14|            the earth as a whole so move. For it is the nature of
 86  II,  14|         the nature of the whole to move to the point to which the
 87  II,  14|       force greater than itself to move it, it must needs stay at
 88  II,  14|          it is still its nature to move. Such is the difficulty.
 89  II,  14|           necessarily continues to move until it occupies the centre
 90 III,  2 |           follows. They manifestly move, and if they have no proper
 91 III,  2 |          proper movement they must move by constraint: and the constrained
 92 III,  2 |           the vortex? It could not move infinitely; for to traverse
 93 III,  2 |      constrained by one another to move as they do, each must still
 94 III,  2 |      movement is single, they must move with a single motion, and
 95 III,  2 |    necessity, we assert, they must move, and a moved thing which
 96 III,  2 |          no natural impetus cannot move either towards or away from
 97 III,  2 |     Suppose the weightless body to move the distance CD, while B
 98 III,  2 |         since the heavy thing must move further. Let the heavy body
 99 III,  2 |         part must in the same time move the distance CD. A weightless
100 III,  2 |          one which has weight will move the same distance, which
101 III,  2 |         further will a given force move it. Now let A, the weightless
102 III,  2 |        which will in the same time move the distance CE, since the
103 III,  2 |           the weightless body will move the same distance as the
104 III,  2 |            constraint continues to move when that which gave the
105 III,  5 |        quantity the more they will move, just as fire, in proportion
106 III,  5 |         quantity makes many things move the faster downward. For
107 III,  6 |            place in which it might move, either by constraint, i.e.
108  IV,  1 |           constant nature it is to move away from the centre, while
109  IV,  1 |           the centre, while others move constantly towards the centre;
110  IV,  2 |        earth and all earthy things move downwards or towards the
111  IV,  2 |             which disposes fire to move upward. If it were, the
112  IV,  2 |           fire the slower it would move, owing to the increase of
113  IV,  2 |      downward, the small mass will move quicker and the large slower.
114  IV,  2 |            in other words why some move upward and others downward.
115  IV,  2 |       bodies which have weight and move downward, while, on the
116  IV,  2 |         void which does not itself move. If, however, it is the
117  IV,  2 |            the nature of a void to move upward and of a plenum to
118  IV,  2 |          upward and of a plenum to move downward, and therefore
119  IV,  2 |       place. But if the void is to move, it must have a place out
120  IV,  3 |           question why some bodies move always and naturally upward
121  IV,  3 |       downward, while others again move both upward and downward.
122  IV,  3 |      fragments of earth would each move not towards it but to the
123  IV,  3 |       continent of all things that move upward or downward is the
124  IV,  4 |           bottom of all things and move towards the centre. But
125  IV,  4 |      things-and we observe fire to move upward even in air itself,
126  IV,  5 |            is removed, it will not move upward to the place of fire,
127  IV,  5 |          the water. Nor does water move upward to the place of air,
128  IV,  5 |           earth. As earth fails to move upward, so fire fails to
129  IV,  5 |           upward, so fire fails to move downward when air is withdrawn
130  IV,  5 |           lightness. The other two move downward when the body beneath
131  IV,  5 |             either all things will move upward or all things will
132  IV,  5 |          upward or all things will move downward, and the second
133  IV,  5 |           there will be nothing to move uniformly downward. Further,
134  IV,  5 |            the intermediate bodies move downward in some cases quicker
