1 I, 1 | gone on to infinity. But Nature flies from the infinite, 2 I, 1 | unending or imperfect, and Nature ever seeks an end.~But all 3 I, 1 | else, inasmuch as their nature resembles that of plants, 4 I, 1 | the spontaneous action of Nature, arising either from decomposition 5 I, 2 | in the ordinary course of Nature; but we must observe carefully 6 I, 3 | so-called eggs are of the nature of a uterus. It is particularly 7 I, 4 | cause of the testes. Now if Nature makes everything either 8 I, 6 | should be speedy. Such is the nature of fish and serpents. Fish 9 I, 8 | animals and plants whose nature is analogous to theirs, 10 I, 8 | down than high up, when Nature has no other business in 11 I, 10| because they are of a cold nature, not hot as some assert, 12 I, 11| little heat and so their nature does not complete the process 13 I, 11| beginning all have it low, Nature here having no other business 14 I, 12| known as the scrotum. If the nature of the skin is opposed to 15 I, 15| attitude is necessary, because Nature has bent backwards the end 16 I, 16| other large insects whose nature it is to unite; most insects 17 I, 17| and generally what is the nature of semen, and of the so-called 18 I, 18| in this case of similar nature but a kind of scolex. It 19 I, 18| semen is to be of such a nature that from it as their origin 20 I, 18| case of all animals whose nature it is to unite; semen is 21 I, 18| question what the primary nature of what is called semen 22 I, 18| neither is it contrary to Nature nor a defect, for it exists 23 I, 18| But these are contrary to Nature, and from such arises nothing 24 I, 18| arises nothing according to Nature. So then it must be a secretion 25 I, 18| shall say it is that whose nature is to go to all of it, and 26 I, 18| and to a departure from Nature.~A further proof that it 27 I, 18| place has been set apart by Nature for waste-products but they 28 I, 18| result because such is the nature of the secretion. For the 29 I, 19| 2) that being of such a nature it should be a mass of sanguineous 30 I, 19| and (3) since that which Nature endows with a smaller portion 31 I, 19| thing that is according to Nature).~It is clear then that 32 I, 20| to the coldness of their nature). As then diarrhoea is caused 33 I, 20| the semen differs in its nature in plants and animals. A 34 I, 20| in two sexes the body and nature of the active and the passive 35 I, 20| catamenia have in their nature an affinity to the primitive 36 I, 21| emit anything of such a nature as to exist within that 37 I, 21| some animals, as birds, the nature of the female unassisted 38 I, 22| varying with the varying nature of the object made. In like 39 I, 22| animals which emit semen Nature uses the semen as a tool 40 I, 22| of weakness in such males Nature is not able to do anything 41 I, 22| scarcely strong enough when Nature herself watches over them. 42 I, 23| more than in plants, their nature desiring that they shall 43 I, 23| made out of both.~It is the nature of those creatures which 44 I, 23| existing in them.~In all this Nature acts like an intelligent 45 I, 23| union of male and female, Nature has mixed these and set 46 II, 1 | always, in virtue of its own nature, the cause of the better 47 II, 1 | should be of an eternal nature, therefore that which comes 48 II, 1 | better and more divine in its nature than the material on which 49 II, 1 | more independent in their nature, so that they have greater 50 II, 1 | are more perfect in their nature and participate in a purer 51 II, 1 | which are hotter in their nature and have more moisture and 52 II, 1 | lung but drier in their nature, or are colder but have 53 II, 1 | rather of a dry and earthy nature, the egg they produce is 54 II, 1 | because they are of an earthy nature and the egg they produce 55 II, 1 | because they are of an earthy nature, lay eggs with a hard integument.~ 56 II, 1 | themselves bodies of a sticky nature, preserve in the same way 57 II, 1 | must observe how rightly Nature orders generation in regular 58 II, 1 | is perfect. Those whose nature is still colder than these 59 II, 1 | in all the productions of Nature or of art, what already 60 II, 1 | that, in all products of Nature or art, a thing is made 61 II, 1 | Now the semen is of such a nature, and has in it such a principle 62 II, 1 | whereas the movement of Nature exists in the product itself, 63 II, 1 | itself, issuing from another nature which has the form in actuality.~ 64 II, 2 | to be mooted concerns the nature of semen. For whereas when 65 II, 2 | hence semen is liquid in its nature because it is made of water. 66 II, 2 | noticed that semen is of the nature of foam; at least it was 67 II, 3 | dishonour, so differs also the nature of the corresponding matter. 68 II, 3 | other residuum of the animal nature there may be, this also 69 II, 3 | has a liquid and watery nature. Therefore we ought not 70 II, 4 | 4~In those animals whose nature is comparatively imperfect, 71 II, 4 | convey, nor is the female nature able to concoct it, because 72 II, 4 | reasons given; for, the female nature being unable to concoct 73 II, 4 | vessels must overflow. Then Nature, aiming at the best end, 74 II, 4 | violence and contrary to nature.~We have thus stated the 75 II, 4 | thick and of a more material nature).~If there is no external 76 II, 4 | superfluous proceeding, and Nature does nothing superfluous.~ 77 II, 4 | catamenia being of the same nature)—when, I say, the more solid 78 II, 4 | potentially locomotive. So Nature has first designed the two 79 II, 4 | there is something of this nature, the substance which at 80 II, 4 | does it form the product of nature. For the material by which 81 II, 4 | generative soul, and this is the nature of every organism, existing 82 II, 5 | would exist in vain, and Nature makes nothing in vain. Hence 83 II, 5 | first, and the first last, Nature running a double course, 84 II, 6 | principle and end of all their nature, this must be the first 85 II, 6 | the organic parts whose nature is to bring others into 86 II, 6 | else but are not of the nature of beginnings must come 87 II, 6 | in the former it is the nature of the male parent that 88 II, 6 | mere deprivation of heat. Nature makes use of both; they 89 II, 6 | vertebrates it is rather of the nature of fat. In all of these 90 II, 6 | are not of too earthy a nature the fat is collected under 91 II, 6 | hardness, exactly as if Nature were a painter producing 92 II, 6 | is such a part. But since Nature makes nothing superfluous 93 II, 6 | is plain that such is the nature of the eyelids, for if the 94 II, 6 | over from the other. For Nature, like a good householder, 95 II, 6 | of the embryo itself does Nature form from the purest material 96 II, 6 | wait till the time when Nature has some residue to spare.~ 97 II, 6 | They have actually the same nature as the bones, and are formed 98 II, 6 | their detrition. And so Nature has contrived well to meet 99 II, 6 | bones, and so have the same nature, even when the bones have 100 II, 6 | unless in cases contrary to Nature), because when they are 101 II, 6 | unless in cases contrary to Nature) is born without them.~The 102 II, 7 | when it is perfected. For Nature sends the sanguineous nutriment 103 II, 7 | those also unite whose nature is near akin and whose form 104 II, 7 | The reason is that the nature of the semen is similar 105 II, 7 | for the first principle of nature is there, so that the movements 106 II, 8 | there are born in course of nature male and female of the same 107 II, 8 | ass is an animal of cold nature, and so is not wont to be 108 II, 8 | been said of such a cold nature, its semen also must be 109 II, 8 | difficulty of a cross contrary to nature is added, (when too even 110 II, 8 | sterile and contrary to nature, will need nothing further 111 III, 1 | made from residual matter, nature cannot afford to spend much 112 III, 1 | seminal secretion, what Nature takes from the one place 113 III, 1 | because it is of a cold nature, as is shown by the cowardice 114 III, 1 | less obvious because their nature is colder. The secretion 115 III, 1 | a lascivious and fertile nature, so that the impulse they 116 III, 1 | Now in animals of a hotter nature the part from which the 117 III, 1 | for they are of a moister nature and are colder than the 118 III, 1 | which are both of a cold nature and also moister (such is 119 III, 2 | the remaining part. For Nature not only places the material 120 III, 2 | another part, in the breasts, Nature does this for birds in the 121 III, 2 | and need the mother-bird. Nature seems to wish to implant 122 III, 2 | always, for being of a hot nature they make the moisture in 123 III, 2 | overboil so to say. For the nature of the white is opposed 124 III, 2 | because though earthy in nature it is only so in the same 125 III, 2 | membranes, as being different in nature. The precise details of 126 III, 3 | externally. The reason is the nature of its body, for its head 127 III, 3 | are of a moist and soft nature, for they are sheltered 128 III, 3 | for the egg is of the same nature both at the point of attachment 129 III, 4 | effected in animals by the nature of the vital heat, in yeasts 130 III, 4 | of fish is prolific, for Nature makes up for the destruction 131 III, 4 | instead of numerous, what Nature has taken away in number 132 III, 7 | required for copulation, as Nature prefers to expend the milt 133 III, 7 | kind of cock change their nature to that of the later cock. 134 III, 7 | any kind of fish of such a nature as to generate without a 135 III, 8 | and therefore of a cold nature.~In the sepias and calamaries 136 III, 9 | imperfect embryo is of such a nature; and in all animals, even 137 III, 9 | into parts; now such is the nature of the scolex. After this 138 III, 9 | first from a formation this nature. I say that the former generate 139 III, 9 | products that are of the nature of a scolex, after progressing 140 III, 9 | reason of this is that their nature, because of its imperfection, 141 III, 9 | an egg is also of such a nature that when it has reached 142 III, 10| and the drones male, for Nature does not give weapons for 143 III, 10| since what is according to Nature is always in due order, 144 III, 10| beautifully is this arranged by Nature that the three kinds always 145 III, 10| of the former, but where Nature has taken away from them 146 III, 10| quickly something of the nature of a scolex and of a considerable 147 III, 11| the former. Because their nature answers to that of plants, 148 III, 11| earth, so much does the nature of testacea differ from 149 III, 11| those on the land. For the nature of liquid is more plastic 150 III, 11| no blood and not of a hot nature are not produced in lakes 151 III, 11| bloodless and of a cold nature. For they seek at the same 152 III, 11| fresh water and hot in its nature; it has a share in all the 153 III, 11| by something of a seminal nature. We must not, however, consider 154 III, 11| useless material, in the other Nature does so. Animals and plants 155 III, 11| have but little blood by nature, are nevertheless sanguinea, 156 III, 11| body of the eel, have the nature of a scolex.~Hence one might 157 IV, 1 | says in the words: "But the nature of the limbs hath been sundered, 158 IV, 1 | it is a sign of a hotter nature, whereas the truth is just 159 IV, 1 | the male organs.~Again, Nature gives both the faculty and 160 IV, 1 | sanguineous nutriment. And Nature assigns to each of the secretions 161 IV, 1 | the uterus is of such a nature, this being the part by 162 IV, 2 | catamenia occur in the course of nature rather when the month is 163 IV, 2 | as products of art or of Nature exist in virtue of a certain 164 IV, 3 | monstrosity; for in these cases Nature has in a way departed from 165 IV, 3 | principle, if it lose its own nature, changes to its opposites, 166 IV, 3 | quantity of their food their nature is not able to master it 167 IV, 4 | stated later, but in them Nature has made an advance towards 168 IV, 4 | invades animals of such a nature. So, too, it is in these 169 IV, 4 | class of things contrary to Nature, not any and every kind 170 IV, 4 | not any and every kind of Nature, but Nature in her usual 171 IV, 4 | every kind of Nature, but Nature in her usual operations; 172 IV, 4 | nothing can happen contrary to Nature considered as eternal and 173 IV, 4 | that which is contrary to Nature is in a certain sense according 174 IV, 4 | certain sense according to Nature, whenever, that is, the 175 IV, 4 | whenever, that is, the formal nature has not mastered the material 176 IV, 4 | not mastered the material nature. Therefore they do not call 177 IV, 4 | reason is that it is in its nature intermediate between white 178 IV, 4 | so to say, contrary to Nature; at least, is it not a change 179 IV, 4 | not a change into another nature. But in animals producing 180 IV, 4 | only depart a little from Nature commonly live; not so those 181 IV, 4 | But in the smaller animals Nature takes away from the size 182 IV, 4 | those intermediate in size Nature has assigned the intermediate 183 IV, 4 | than what is according to Nature. In like manner, if the 184 IV, 4 | be multiplied contrary to Nature is the same as the cause 185 IV, 4 | than is required by the nature of the part. The result 186 IV, 4 | nourishment as being contrary to Nature; it is attached like a growth ( 187 IV, 4 | body proper and contrary to Nature.) If the formative power 188 IV, 5 | the barrenness of their nature and because their uterus 189 IV, 5 | however, this is contrary to Nature, so that the embryo suffers, 190 IV, 5 | animals it is according to Nature, for their body is so formed 191 IV, 6 | striving as it were with the nature of the solid-hoofed animals. 192 IV, 6 | are weaker and colder in nature, and we must look upon the 193 IV, 6 | is of what is formed by Nature. For the reason just given 194 IV, 6 | in man it is contrary to Nature that they should run an 195 IV, 6 | however, it is not contrary to Nature. A difference is also found 196 IV, 7 | maternal heat. (For their nature seems to be incapable, and 197 IV, 7 | a long time, for in its nature it is neither perfect nor 198 IV, 8 | for the time of birth. For Nature has made it for the sake 199 IV, 8 | anything chance contrary to Nature. In the other animals the 200 IV, 8 | female are of a sanguineous nature, and the first principle 201 IV, 8 | That milk has the same nature as the secretion from which 202 IV, 8 | same as that from which Nature forms the animal in generation. 203 IV, 8 | do not occur according to Nature, nor do they conceive; if 204 IV, 8 | up. This is because the nature of the milk and of the catamenia 205 IV, 8 | catamenia is the same, and Nature cannot be so productive 206 IV, 8 | say that it is contrary to Nature, for in all cases where 207 IV, 8 | is what is "according to Nature".~The time also at which 208 IV, 10| other circumstances of its nature, of which we will speak 209 IV, 10| It is the aim, then, of Nature to measure the coming into 210 IV, 10| from being according to Nature, and often cause things 211 IV, 10| to fall out contrary to Nature.~We have now spoken of the 212 V, 1 | things are not the product of Nature working upon the animal 213 V, 1 | and ordered products of Nature, we must not say that each 214 V, 1 | above, because it is its nature to act or be acted on in 215 V, 1 | sleep seems to be in its nature such a condition, being 216 V, 1 | themselves, for they are not of a nature to have more than one colour. 217 V, 1 | the reverse, but also the nature of the skin upon what is 218 V, 1 | too much. Whenever then Nature cannot make the eyes correspond 219 V, 2 | and material, and he is by nature the thinnest-skinned of 220 V, 2 | size.~The workmanship of Nature is admirable also in the 221 V, 3 | of fish.~For what purpose Nature has made hair in general 222 V, 3 | the skin is of an earthy nature; being on the surface of 223 V, 3 | hair, in the others the nature of the climate is the cause. 224 V, 3 | for these, too, are by nature less hot and moist than 225 V, 3 | not go bald because their nature is like that of children, 226 V, 4 | their colour, it is the nature of the skin that is the 227 V, 5 | white, this is caused by nature, not by any affection. The 228 V, 6 | those animals of which by nature the individual is whole-coloured 229 V, 6 | differ from those white by nature, so also in the hair the 230 V, 6 | differs from that due to nature in that the cause is different; 231 V, 6 | cold are the causes of the nature of the skin and hair, each 232 V, 7 | especially plain in man, for Nature has given this faculty to 233 V, 7 | to belong to the nobler nature, and in songs the deep note 234 V, 7 | because of their female nature, the part by which they 235 V, 7 | heart of bulls is of such a nature is shown by the fact that 236 V, 8 | that they grow according to Nature, and suckling is the cause 237 V, 8 | assumption upon what we see, that Nature never fails nor does anything 238 V, 8 | time of reaching maturity, Nature would fail in something 239 V, 8 | besides, the operation of Nature would be contrary to Nature, 240 V, 8 | Nature would be contrary to Nature, for what is done by violence 241 V, 8 | violence is contrary to Nature, and it is by violence that 242 V, 8 | necessity all the operations of Nature. Now they are necessary, 243 V, 8 | So it is reasonable that Nature should perform most of her 244 V, 8 | living things formed by Nature. But to say that necessity
