"[E]ven if we were to accept that ecosystems do have intrinsic moral worth, that still does not show that we have a duty to protect them as they function presently. Their value might be intrinsic, but that is not the same as absolute. As such, their value has to be balanced against other moral values, including the value of being free from suffering. Crucially, it is extremely difficult to believe that the value of 'continued biological flourishing' trumps the value of 'freedom from suffering'. After all, when we are confronted by threats to humans from malaria, smallpox, the HIV virus, and so on, the value of freedom from suffering has priority over biological functioning every time. A truly impartial sentientist politics demands that the freedom of suffering of all sentient creatures should enjoy that same priority."
"Nowadays, there is very little we can do about [wild animal suffering]. But it is critical to start questioning the idea that we should not do anything. This is crucial so that in the future, some day, the problem can be addressed. If a community of human beings is stricken by a flood, a famine, violence, or is stricken by an epidemic, we think that if there is something we can do to help them, we should do it. Why not in the case of nonhuman animals? Normally we think that this is the way life in the wild. However, few of us who state this would be willing to let other humans die of disease, starvation or cannibalism. What is the reason for this different consideration of humans and other animals? Many reasons can be given, but all of them are merely excuses. The real motive of this dissimilar attitude is speciesism. Moreover, none of us would like to be left to die suffering in conditions such as the ones described above. In this way, if we are neither egotistical nor speciesist, and we therefore assume that we are willing to treat other animals as we would like to be treated, then we must conclude two things: not only should we care about the animals that are exploited by human beings, but we also must care about the animals that live in freedom. We must reflect on what we can do for them. This is the consequence of antispeciesism that is the most difficult to accept, and it is, in fact, a reason why many animal rights advocates are not really capable of taking a antispeciesist stance. Only those who are truly capable of leaving their most deeply rooted speciesist prejudices behind can manage to address this question. But if - as I have said above - speciesism is an unjustifiable position, we must have enough courage and responsibility to not look the other way."
"The animal liberation movement is fighting what is arguably the most entrenched and widespread form of exploitation in human history: speciesism."
"Ethics, in our part of the world, may be considered to have advanced, at least in its pretensions, to the anthropocentric stage of evolution. Aggregation has advanced from individual to tribe, and from tribe to race, and from race to sex, and from sex to species, until to-day the ethical conception of many minds includes, with greater or less vividness and sincerity, all sexes, colors, and conditions of men. The fact that an animal is a human, that is, that he belongs to the hominine species of beings, entitles him, regardless of his imperfections, to some sort of consideration."
"Since we all inhabit the earth, we are all considered earthlings. There is no sexism, racism, or speciesism in the term 'earthling'. It encompasses each and every one of us: warm or cold-blooded, mammal, vertebrate or invertebrate, bird, reptile, amphibian, fish and human alike."
"[S]upposing the Deity to be ... omnipotent—and there can be no inference more transparent than that such wholesale suffering, for whatever ends designed, exhibits an incalculably greater deficiency of beneficence in the divine character than that which we know in any, the very worst, of human characters. For let us pause for one moment to think of what suffering in nature means. Some hundreds of millions of years ago some millions of millions of animals must be supposed to have been sentient. Since that time till the present, there must have been millions and millions of generations of millions of millions of individuals. And throughout all this period of incalculable duration, this inconceivable host of sentient organisms have been in a state of unceasing battle, dread, ravin, pain. Looking to the outcome, we find that more than half of the species which have survived the ceaseless struggle are parasitic in their habits, lower and insentient forms of life feasting on higher and sentient forms; we find teeth and talons whetted for slaughter, hooks and suckers moulded for torment—everywhere a reign of terror, hunger, and sickness, with oozing blood and quivering limbs, with gasping breath and eyes of innocence that dimly close in deaths of brutal torture! Is it said that there are compensating enjoyments? I care not to strike the balance; the enjoyments I plainly perceive to be as physically necessary as the pains, and this whether or not evolution is due to design."
"In a way, Darwin discovered God—a God that failed to match the preconceptions of theology, and so passed unheralded. If Darwin had discovered that life was created by an intelligent agent—a bodiless mind that loves us, and will smite us with lightning if we dare say otherwise—people would have said "My gosh! That's God!" But instead Darwin discovered a strange alien God—not comfortably "ineffable", but really genuinely different from us. Evolution is not a God, but if it were, it wouldn't be Jehovah. It would be H. P. Lovecraft's Azathoth, the blind idiot God burbling chaotically at the center of everything, surrounded by the thin monotonous piping of flutes. Which you might have predicted, if you had really looked at Nature."
"Why is Nature cruel? You, a human, can look at an Ichneumon wasp, and decide that it's cruel to eat your prey alive. You can decide that if you're going to eat your prey alive, you can at least have the decency to stop it from hurting. It would scarcely cost the wasp anything to anesthetize its prey as well as paralyze it. Or what about old elephants, who die of starvation when their last set of teeth fall out? These elephants aren't going to reproduce anyway. What would it cost evolution—the evolution of elephants, rather—to ensure that the elephant dies right away, instead of slowly and in agony? What would it cost evolution to anesthetize the elephant, or give it pleasant dreams before it dies? Nothing; that elephant won't reproduce more or less either way."
"Once Darwin fathomed natural selection, he surely saw how deeply his ethics were at odds with the values it implies. The insidious lethality of a parasitic wasp, the cruelty of a cat playing with a mouse — these are, after all, just the tip of the iceberg. To ponder natural selection is to be staggered by the amount of suffering and death that can be the price for a single, slight advance in organic design. And it is to realize, moreover, that the purpose of this "advance" — longer, sharper canine teeth in male chimpanzees, say — is often to make other animals suffer or die more surely. Organic design thrives on pain, and pain thrives on organic design."
"It seems the insect kinds were at least one degree above the inhabitants of the waters. Almost all these too devour one another, and every other creature which they can conquer. Indeed, such is the miserably disordered state of the world at present, that innumerable creatures can not otherwise preserve their own lives than by destroying others. But in the beginning it was not so. The paradisiacal earth afforded a sufficiency of food for all its inhabitants; so that none of them had any need or temptation to prey upon the other. The spider was then as harmless as the fly, and did not then lie in wait for blood. The weakest of them crept securely over the earth, or spread their gilded wings in the air, that wavered in the breeze, and glittered in the sun, without any to make them afraid."
"There is, perhaps, no way in which one can obtain a more vivid idea of the intensity of the struggle for existence among organic beings than by the study of the inhabitants of a freshwater pond of long standing. Every inch of space in such a situation is teeming with life, both animal and vegetable, and the chief delight of most of the animals present is to wage a ceaseless warfare upon their weaker fellows."
"[T]here were no birds or beasts of prey; none that destroyed or molested another."
"I wonder if a sillier and more ignorant catachresis than "Mother Nature" was ever perpetrated? It is because Nature is ruthless, hideous, and cruel beyond belief that it was necessary to invent civilisation. One thinks of wild animals as savage, but the fiercest of them begins to look almost domesticated when one considers the viciousness required of a survivor in the sea; as for the insects, their lives are sustained only by intricate processes of fantastic horror. There is no conception more fallacious than the sense of cosiness implied by 'Mother Nature.' Each species must strive to survive, and that will do, by every means in its power, however foul—unless the instinct to survive is weakened by conflict with another instinct."
"I am a puny part of the great whole. Yes; but all animals condemned to live, All sentient things, born by the same stern law, Suffer like me, and like me also die."
"When it comes to wild animals, though, only the last [expression of normal behaviour] is guaranteed. They have to struggle to survive on a daily basis, from finding food and water to another individual to mate with. They don't have the right to comfort, stability, or good health. ... By the standards our governments have set, the life of a wild animal is cruelty."
"The simple facts are that both predation and starvation are painful prospects for deer, and that the lion's lot is no more enviable."
"There is, to be sure, a risk that interventions to help wild animals will end up making things worse, which highlights the importance of a well-informed and cautious approach to compassionate intervention. Yet this is very different from a stance of moral defeatism that simply dismisses the issue out of hand."
"The vulture fastens on his timid prey, And stabs with bloody beak the quivering limbs: All's well, it seems, for it. But in a while An eagle tears the vulture into shreds; [...] Thus the whole world in every member groans: All born for torment and for mutual death."
"... this is, I believe, the great blindspot of most vegans: the absence of a perpetrator leads them to neglect the suffering of the majority of the beings they claim to care about."
"Why did nature not ordain that one animal should not live by the death of another? Nature, being inconstant and taking pleasure in creating and making constantly new lives and forms, because she knows that her terrestrial materials become thereby augmented, is more ready and more swift in her creating, than time in his destruction; and so she has ordained that many animals shall be food for others. Nay, this not satisfying her desire, to the same end she frequently sends forth certain poisonous and pestilential vapours upon the vast increase and congregation of animals; and most of all upon men, who increase vastly because other animals do not feed upon them; and, the causes being removed, the effects would not follow. This earth therefore seeks to lose its life, desiring only continual reproduction; and as, by the argument you bring forward and demonstrate, like effects always follow like causes, animals are the image of the world."
"... wild animals suffer from a wide range of harms regardless of their reproductive strategies, including hunger, disease, parasitism, and natural disasters. These harms often cause intense suffering, and we should not disregard this suffering merely because the sufferers happen to live in the wild, or because they happen to have non-human bodies. We rightly acknowledge a moral duty to relieve intense suffering experienced by humans, including when it is due to natural causes, and there is no justification for restricting this moral duty to humans only ... ."
"Elements, animals, humans, everything is at war."
"Why is so much of Nature at war with other parts of Nature? Because there isn't one Evolution directing the whole process. There's as many different "evolutions" as reproducing populations. Rabbit genes are becoming more or less frequent in rabbit populations. Fox genes are becoming more or less frequent in fox populations. Fox genes which construct foxes that catch rabbits, insert more copies of themselves in the next generation. Rabbit genes which construct rabbits that evade foxes are naturally more common in the next generation of rabbits. Hence the phrase "natural selection"."
"Why did I feed these animals against all advice? Because we live in the same place, because they were individuals, because they had relatives, experience, a past, and desires, because they were cold and hungry, because they hadn't found enough to eat in the fall, because each had just one life."
"If we humans could 'civilize' wildlife, and provide better living and dying conditions to non-human animals, then we ought to do so. We ought to side with the lamb against the wolf."
"The ignorant creature knows nothing of the wise doctrines of Malthus, but spawns forth as many children of all sorts as ever she can, without the least prudential restraint. She has consequently far more than she can properly feed and rear; so that a large part perishes in infancy (and we are told that none of these except the human sucklings will rise to another life; poor bereaved monkey and donkey mothers, for instance, being altogether without the precious consolations of immortality); a considerable part is eaten up by mankind and other hungry animals, and the remainder can seldom get food enough."
"What happens in wildlife is indeed of moral concern, according to utilitarianism. When there is famine among the antelopes, the utilitarian sees a problem. It is as bad when wild animals suffer from natural causes, as it is when they are treated badly in the food industry. To the moral rights theorist ... it is not a moral problem when the wolf kills the lamb. It is a problem from the point of view of utilitarianism, however. If there is anything one can do about it, one should not hesitate to do it."
"The Gods! but they, the shadows of ourselves, Have past for ever. It is Nature kills, And not for her sport either. She knows nothing. Man only knows, the worse for him! for why Cannot he take his pastime like the flies? And if my pleasure breed another’s pain, Well—is not that the course of Nature too, From the dim dawn of Being—her main law Whereby she grows in beauty—that her flies Must massacre each other? this poor Nature!"
"Is there anything we can do about animal suffering in wildlife? There was a time when many said that nothing should be done to obviate human suffering, since attempts to establish a welfare state would either be in vain, jeopardise what kind of welfare there happens to exist, or produce perverse (even worse) results. We rarely meet with that reaction any more. However, many seem to be ready to argue that wildlife constitutes such a complex system of ecological balances that any attempt to interfere must produce no good results, put into jeopardy whatever ecological 'balances' there happen to exist, or perversely make the situation even worse. This is not the place to settle whether they are right or not, but, certainly, there must exist some measures we could take, if we bothered to do so, rendering wildlife at least slightly less terrible. If this were so, we should do so, according to utilitarianism."
"Just within the edge of the wood there, I see a small painted turtle on its back, with its head stretched out as if to turn over. Surprised by the sight, I stooped to investigate the cause. It drew in its head at once, but I noticed that its shell was partially empty. I could see through it from side to side as it lay, its entrails having been extracted through large openings just before the hind legs ... Such is Nature, who gave one creature a taste or yearning for another's entrails as its favorite tidbit!!"
"So, Nat'ralists observe, a Flea Hath smaller Fleas that on him prey, And these have smaller Fleas to bite 'em, And so proceed ad infinitum"
"Hobbes clearly proves that ev'ry Creature Lives in a State of War by Nature. The Greater for the Smallest watch, But meddle seldom with their Match. A Whale of moderate Size will draw A Shole of Herrings down his Maw. A Fox with Geese his Belly crams; A Wolf destroys a thousand Lambs."
"Who trusted God was love indeed And love Creation's final law — Tho' Nature, red in tooth and claw With ravine, shriek'd against his creed —"
"[C]onsider the sea-hare Tethys, a shell-less, flabby sea-slug, actually a marine snail, which may be seen crawling about in tidal estuaries, somewhat resembling a rabbit crouched over. A California biologist estimated the number of eggs produced by a single animal during a single breeding season to be more than 478 million. And the adults sometimes occur by the hundred! Obviously all these eggs cannot mature, all this potential cannot, must not, become reality, else the ocean would soon be occupied exclusively by sea-hares. There would be no kindness in that, even for the sea-hares themselves, for in a few generations they would overflow the earth; there would be nothing for the rest of us to eat, and nothing for them unless they turned cannibal. On the average, probably no more than the biblical one or two attain full maturity. Somewhere along the way all the rest will have been eaten by predators whose life cycle is postulated upon the presence of abundant larvae of sea-hares and other forms as food—as all life itself is based on such a postulate."
"Although disease and suffering in animals are unpleasant and, perhaps, regrettable, biologists recognize that conservation is engaged in the protection of the integrity and continuity of natural processes, not the welfare of individuals. At the population level, the important processes are ultimately genetic and evolutionary because these maintain the potential for continued existence. Evolution, as it occurs in nature, could not proceed without the suffering inseparable from hunger, disease, and predation. For this reason, biologists often overcome their emotional identification with individual victims. For example, the biologist sees the abandoned fledgling or the wounded rabbit as part of the process of natural selection and is not deceived that "rescuing" sick, abandoned, or maimed individuals is serving the species or the cause of conservation. (Salvaging a debilitated individual from a very small population would be an exception, assuming it might eventually contribute to the gene pool.) Therefore, the ethical imperative to conserve species diversity is distinct from any societal norms about the value or the welfare of individual animals or plants. This does not in any way detract from ethical systems that provide behavioral guidance for humans on appropriate relationships with individuals from other species, especially when the callous behavior of humans causes animals to suffer unnecessarily. Conservation and animal welfare, however, are conceptually distinct, and they should remain politically separate."
"Is there not a teaching of nature very apt to suggest horror and despair rather than a complacent brooding over soothing thoughts?"
"For nature is one with rapine, a harm no preacher can heal; The Mayfly is torn by the swallow, the sparrow spear'd by the shrike, And the whole little wood where I sit is a world of plunder and prey."
"[N]ature appears with many animals to have been rather a cruel stepmother than a mother, and with others not a stepmother, but a most tender mother"
"Sometimes, especially in inclement weather, incubating birds continue to cover their eggs while hungry, and even when they would appear to be suffering acutely from a long-continued fast. Many marine birds, especially of the penguin and petrel families, remain on their nests for days or even weeks without eating; and some Emperor Penguins, who incubate single eggs on the ice in the frigid gloom of midwinter at the edge of the Antarctic continent, pass about two months in an absolute fast. Must not birds at times experience gnawing pangs of hunger, while they slowly become emaciated from lack of nourishment?"
"The wild life of nature, regarded simply as woodland glades, murmuring brooks, fragrant flowers and songful birds, or the tranquil emptiness of a seascape in calm weather, is restful and refreshing after the clangor and turmoil of human existence, especially in the crowded centers of population. Its myriad shapes and colors divert the fevered mind from its too-absorbing problems. But viewed with a more penetrating and philosophic eye, what spectacle could be more hideously revolting than that of countless animals, each busily stuffing itself with as many other living things as its maw can hold? Were this all that we could detect beneath the seemingly tran-quil face of nature, some who now turn to it for spiritual comfort and refreshment might shrink away in horror."
"Animals more obviously violate the concept of goodness, for none can live without tearing and devouring other organized beings, whether vegetables or other animals, or else sapping their strength as noxious parasites. The larger ambulatory animals can hardly move without crushing the herbage and multitudes of small creeping things; and all compete with each other for space and nourishment in the same manner as plants, but often far more violently. Moreover, they struggle for mates in a fashion wholly unknown among vegetables, even the milder herbivores sometimes exhibiting in their quarrels with rivals a fury that astounds us. Thus none is wholly good; yet those which devour only vegetation seem to be endowed by nature with a capacity for goodness lacking in those which kill and tear for food creatures more akin to themselves; while the fiercest kinds, which destroy living things that they do not require to sustain their own lives, fall most conspicuously short of goodness."
"[If evolution had been guided, the Earth would have become] the abode of a vast diversity of creatures dwelling in concord (instead of) a place of mixed character, where beauty and ugliness, peace and fear, happiness and horror, mingle together in the most perplexing contrasts."
"The evolutionary impulsion to increase fecundity, technically known as fitness, at whatever cost is responsible for most of the ugliness, strife, and suffering that afflict the living community on the fairest planet illuminated by the Sun."
"That evolution has accomplished much that is splendid and admirable, it would be ungrateful to deny. That the means it has employed have often been ruthlessly harsh is a proposition to which every compassionate person will attest."
"Beyond the limits of the most comprehensive actual society are living creatures whom our moral impulse bids us to include within our system of organized, reciprocal relations, although up to the present we have found this impossible to achieve. Nevertheless, we can at least reach out to help them when in distress, as by rescuing them from the pools and pits into which they sometimes fall, feeding them when hungry as far as our means allow, perhaps at times curing their wounds. Such charity is the truest sort, because we can never expect any extrinsic recompense nor even an indirect economic advantage from it. When we contemplate the vast amount of mutilation, suffering, and death which hourly occurs among the living creatures on this planet, and the complex relations among them which make it impossible for us to help one of them without perhaps indirectly injuring another, we sometimes suspect that our most devoted effort on behalf of nonhuman creatures is scarcely more than a gesture. Yet it is a gesture which symbolizes the comprehensive society that we aspire to create."
"I have come to view vegetarianism as a standing protest against predation, which is life's greatest evil. If there were no other argument in its favor, that would be sufficient."
"After long pondering, I believe that I can define good and evil in terms to which even a biologist of the mechanical school can hardly take exception. At least, I fancy that I can do so for evil. The great evil of life is parasitism."
"[Predation is] a great evil that a wise or benevolent creator would have avoided."
"[F]or practical purposes I am fairly sure, judging from man's past record of attempts to mold nature to his own aims, that we would be more likely to increase the net amount of animal suffering if we interfered with wildlife, than to decrease it. Lions play a role in the ecology of their habitat, and we cannot be sure what the long-term consequences would be if we were to prevent them from killing gazelles. ... So, in practice, I would definitely say that wildlife should be left alone ... The remaining question is purely hypothetical, and perhaps it would be politic to refuse to answer it. Nevertheless, philosophers are supposed to answer hypothetical questions, so I will risk it. If, in some way, we could be reasonably certain that interfering with wildlife in a particular way would, in the long run, greatly reduce the amount of killing and suffering in the animal world, it would, I think, be right to interfere."
"In the wild, plagues of excess population are a rarity. The seas are not crowded with sunfish; the ponds are not brimming with toads; elephants do not stand shoulder to shoulder over the land. With few exceptions, animal populations are remarkably stable. On average, of each pair's offspring, only sufficient survive to replace the parents when they die. Surplus young die, and birth rates are balanced by death rates. In the case of spawners and egg layers, some young are killed before hatching. Almost half of all blackbird eggs are taken by jays, but even so, each pair usually manages to fledge about four young. By the end of summer, however, an average of under two are still alive. Since one parent will probably die or be killed during the winter, only one of the young will survive to breed the following summer. The high mortality rate among young animals is an inevitable consequence of high fecundity. Of the millions of fry produced by a pair of sunfish, only one or two escape starvation, disease or predators. Half the young of house mice living on the Welsh island of Skokholm are lost before weaning. Even in large mammals, the lives of the young can be pathetically brief and the killing wholesale. During the calving season, many young wildebeeste, still wet, feeble and bewildered, are seized and torn apart by jackals, hyenas and lions within minutes of emerging from their mothers' bellies. Three out of every four die violently within six months."
