1 I, 2 | Now revolution about the centre is circular motion, while 2 I, 2 | meaning motion away from the centre, and "downward" motion towards 3 I, 2 | or towards or about the centre. This seems to be in exact 4 I, 2 | rotating bodies about the centre is unnatural, it would be 5 I, 2 | straight line away from the centre. On all these grounds, therefore, 6 I, 3 | naturally moves towards the centre, and "light" to that which 7 I, 3 | naturally away from the centre. The heaviest thing will 8 I, 3 | towards or away from the centre. Movement in a straight 9 I, 3 | either from or towards the centre, which, as we know, is impossible); 10 I, 3 | from and motion towards the centre.~ 11 I, 5 | the radii drawn from the centre will be infinite. But the 12 I, 5 | circle, revolving upon C as centre. In its movement it will 13 I, 5 | body.~(5) Again, take a centre C, an infinite line, AB, 14 I, 6 | which moves away from the centre can be infinite. For the 15 I, 6 | determinate also. Now the centre is determined; for, from 16 I, 6 | cannot go farther than the centre. The centre, therefore, 17 I, 6 | farther than the centre. The centre, therefore, being determinate, 18 I, 6 | naturally away from the centre and the other towards it.~ 19 I, 7 | circle. For there is no centre of the infinite, and that 20 I, 7 | a circle moves about the centre. Nor again can the infinite 21 I, 7 | generally, that which has no centre or extreme limit, no up 22 I, 8 | from a certain place to the centre here, its movement from 23 I, 8 | naturally away from the centre and another towards the 24 I, 8 | and another towards the centre, since fire must be identical 25 I, 8 | move naturally also to our centre and its fire to our circumference. 26 I, 8 | upwards, and fire to the centre; in the same way the earth 27 I, 8 | naturally away from the centre when it moves towards the 28 I, 8 | when it moves towards the centre of another universe. This 29 I, 8 | admitting this, we must make the centre and the extremity one as 30 I, 8 | numerically one, i.e. a particular centre or a particular extremity. 31 I, 8 | assumption or assert that the centre and the extremity are each 32 I, 8 | the nearer it is to the centre, and fire the nearer it 33 I, 8 | namely the region about the centre; the place, secondly, of 34 I, 8 | since the region about the centre has been given to the heavy 35 I, 9 | that which moves from the centre or that which lies lowest. 36 II, 2 | upward, and earth only to the centre. It is true that we speak 37 II, 3 | something at rest at the centre of the revolving body; and 38 II, 3 | either elsewhere or at the centre. It could do so only if 39 II, 3 | movement were towards the centre. But the circular movement 40 II, 3 | which is at rest at the centre. (At present we may take 41 II, 4 | bodies between these and the centre. Bodies which are bounded 42 II, 4 | whose position is about the centre. If earth is enclosed by 43 II, 4 | place-"hollow" meaning "nearer the centre". Draw from the centre the 44 II, 4 | the centre". Draw from the centre the lines AB, AC, and let 45 II, 8 | are attached to the same centre. Whenever bodies are moving 46 II, 12| planets are farther from the centre and thus nearer to the primary 47 II, 13| finite-say it lies at the centre. But the Italian philosophers 48 II, 13| the contrary view. At the centre, they say, is fire, and 49 II, 13| circular motion about the centre. They further construct 50 II, 13| the circumference and the centre are limits. Reasoning on 51 II, 13| not earth that lies at the centre of the sphere, but rather 52 II, 13| the world, which is the centre, should be most strictly 53 II, 13| of Zeus", as if the word "centre" were quite unequivocal, 54 II, 13| quite unequivocal, and the centre of the mathematical figure 55 II, 13| the thing or the natural centre. But it is better to conceive 56 II, 13| of animals, in which the centre of the animal and that of 57 II, 13| call in a guard for its centre: rather let them look for 58 II, 13| rather let them look for the centre in the other sense and tell 59 II, 13| nature has set it. That centre will be something primary 60 II, 13| that the earth lies at the centre think that it revolves about 61 II, 13| that it revolves about the centre, and not the earth only 62 II, 13| earth is not actually a centre but distant from it a full 63 II, 13| that we do not dwell at the centre, than on the common view 64 II, 13| we are removed from the centre by half the diameter of 65 II, 13| earth, which lies at the centre, is "rolled", and thus in 66 II, 13| parts came together at the centre was also constrained. (The 67 II, 13| bodies always move to the centre of the whirl. This is thought 68 II, 13| earth came together at the centre. They then seek a reason 69 II, 13| then? Its movement to the centre was constrained, and its 70 II, 13| constrained, and its rest at the centre is due to constraint; but 71 II, 13| the art of earth at the centre, the question remains, why 72 II, 13| that which is set at the centre and indifferently related 73 II, 13| be, which is put at the centre, must stay there. Fire, 74 II, 13| then, will rest at the centre: for the proof turns on 75 II, 13| only that it remains at the centre, but also that it moves 76 II, 13| also that it moves to the centre. The place to which any 77 II, 13| whereas movement to the centre is peculiar to earth. Again 78 II, 13| the earth remains at the centre and not for a reason why 79 II, 13| place. But suppose that the centre is not its place, and that 80 II, 13| and another thing to the centre. Again, their statements 81 II, 13| obliged to remain at the centre. But so far as their argument 82 II, 13| fire. Fire, if set at the centre, should stay there, like 83 II, 13| stops it, away from the centre to the extremity. It will 84 II, 13| this manner away from the centre, unless the centre had been 85 II, 13| from the centre, unless the centre had been its natural place.~ 86 II, 14| others who, setting it at the centre, suppose it to be "rolled" 87 II, 14| whether the earth be at the centre or away from it, must needs 88 II, 14| in a straight line to the centre. Being, then, constrained 89 II, 14| whether it move about the centre or as stationary at it, 90 II, 14| and whole alike, is the centre of the whole-whence the 91 II, 14| centres are the same, which centre it is that portions of earth 92 II, 14| their goal because it is the centre of the earth or because 93 II, 14| earth or because it is the centre of the whole? The goal, 94 II, 14| goal, surely, must be the centre of the whole. For fire and 95 II, 14| area which contains the centre. It happens, however, that 96 II, 14| happens, however, that the centre of the earth and of the 97 II, 14| Thus they do move to the centre of the earth, but accidentally, 98 II, 14| the fact that the earth’s centre lies at the centre of the 99 II, 14| earth’s centre lies at the centre of the whole. That the centre 100 II, 14| centre of the whole. That the centre of the earth is the goal 101 II, 14| angles, and thus to a single centre, that of the earth. It is 102 II, 14| the earth must be at the centre and immovable, not only 103 II, 14| lie elsewhere than at the centre.~From what we have said 104 II, 14| move from any point to the centre, as of fire contrariwise 105 II, 14| contrariwise to move from the centre to the extremity, it is 106 II, 14| should move away from the centre except by constraint. For 107 II, 14| and movement away from the centre is the contrary of movement 108 II, 14| earth can move away from the centre, obviously still less can 109 II, 14| it must needs stay at the centre. This view is further supported 110 II, 14| that the earth lies at the centre. Of the position of the 111 II, 14| weight until it reaches the centre, and the jostling of parts 112 II, 14| part and part until the centre is reached. The process 113 II, 14| from every side towards the centre. Whether the parts which 114 II, 14| which came together at the centre were distributed at the 115 II, 14| extremity to the single centre, it is obvious that the 116 II, 14| everywhere equidistant from its centre, i.e. the figure will be 117 II, 14| impulse whose goal is the centre, and the greater weight 118 II, 14| might be argued, is at the centre and spherical in shape: 119 II, 14| added to one hemisphere, the centre of the earth and of the 120 II, 14| will not stay still at the centre, or if it does, it will 121 II, 14| rest without having its centre at the place to which it 122 II, 14| size, moves towards the centre. Clearly it will not stop 123 II, 14| when its edge touches the centre. The greater quantity must 124 II, 14| prevail until the body’s centre occupies the centre. For 125 II, 14| body’s centre occupies the centre. For that is the goal of 126 II, 14| move until it occupies the centre equally every way, the less 127 III, 2 | which is at rest at the centre. If then this rest is natural 128 III, 2 | bodies moving towards the centre and the light bodies away 129 III, 2 | towards or away from the centre. Suppose a body A without 130 IV, 1 | is to move away from the centre, while others move constantly 131 IV, 1 | move constantly towards the centre; and of these movements 132 IV, 1 | that which is away from the centre I call upward movement and 133 IV, 1 | universe has an extremity and a centre, it must clearly have an 134 IV, 1 | pattern all round, with a centre identically related to each 135 IV, 1 | extremity was above and the centre below.) By absolutely light, 136 IV, 1 | moves downward or to the centre. By lighter or relatively 137 IV, 2 | downwards or towards the centre. It cannot then be the fewness 138 IV, 3 | is the extremity and the centre, and this boundary comes 139 IV, 4 | moves uniformly towards the centre. But is also similarly a 140 IV, 4 | things and move towards the centre. But the centre is a fixed 141 IV, 4 | towards the centre. But the centre is a fixed point. If therefore 142 IV, 4 | which sinks moves to the centre. That there is a centre 143 IV, 4 | centre. That there is a centre towards which the motion 144 IV, 4 | be directed towards the centre. Whether it is really the 145 IV, 4 | Whether it is really the centre of the earth and not rather 146 IV, 4 | all things moves to the centre, necessarily that which 147 IV, 4 | bodies takes place. For the centre is opposed as contrary to 148 IV, 4 | light in the spatial duality centre and extremity. Now there 149 IV, 4 | sense both extremity and centre. For this reason there is
