"Torture is permanent in Latin America; is it harmonious? Environmentalists find it good that the fox kills the hare, because that preserves an order. Torture also preserves order."
"It is easy to have an ethics that, instead of questioning things that are difficult to change, decides to call them "good". My ethics, I want to consider it built on real things; happiness and suffering are for me real things, like water or stones, even if current physics does not know them. I cannot then, by convention, baptize anything "good". And also, this implies living in uncertainty, in ethical insecurity. Is it good to kill a snake, to save a large number of frogs? While these eat so many insects? They eat each other or harm plants. I don't know if they suffer, the plants, if they hurt when they choke on each other, poison themselves, get sick shade each other. In many cases, I do not know what is right. Or, what is right is too hard to assume: with each step I risk crushing ants. Maybe I should delete myself, to save ants? I will not do it."
"Faced with the massive destruction of the environment by humans, environmentalists cling to the myth of Mother Nature to be preserved. I am revolted by the extermination of the foxes; this may seem contradictory to my revolt against what hare foxes do. I have a problem there that I cannot solve. And I have others, even more difficult. Why should I, in order to call a problem a problem, be able to suggest a solution, if possible within an hour? No one knows how to beat AIDS, but that does not prevent us from being aware that AIDS is a problem. And above all to seek solutions."
"This discussion may seem purely abstract; neither the lions' vegan diet nor the fight against their predation is still on the agenda. It is undoubtedly preferable, strategically, to concentrate our efforts on the predation committed by the humans, i.e. on their consumption of meat. However, the way we see predation and the solutions we allow ourselves to imagine are not without consequences. There is a strong symbolic value, it seems to me, to affirm that it would be right to prevent predation, even at the cost of the life of the predator. It can also help us to feel more comfortable with the limited interventions that we can now practice in the wild, for example to protect a mouse from an owl. We may feel uncomfortable asking ourselves in Kant's way if we can want the maxim of our act to be a universal law, which would imply that the owl is starving. Accepting that indeed we may want to universalize this maxim can allow us to act more serenely."
"[F]rom an antispeciesist view, which takes the interests of all sentient animals into account, whether they are human or not, what matters most is how their well-being is affected by our actions and omissions. It follows from this view that we have decisive reasons against performing negative interventions in nature (those with an expected net negative value for nonhuman animals). Similarly, it implies that, whenever it is in our power to do so, and if the intervention is expected to bring about more benefits than harms, we have decisive reasons to intervene in nature with the aim of helping the animals that live there."
"These properties of animals, wherever they are found, must, I think, be referred to design; because there is, in all cases of the first, and in most cases of the second, an express and distinct organization provided for the producing of them ... the fangs of vipers, the stings of wasps and scorpions, are as clearly intended for their purpose, as any animal structure is for any purpose the most incontestably beneficial. And the same thing must ... be acknowledged of the talons and beaks of birds, of the tusks, teeth, and claws of beasts of prey, of the shark's mouth, of the spider's web, and of numberless weapons of offence belonging to different tribes of voracious insects. We cannot, therefore, avoid the difficulty by saying, that the effect was not intended. The only question open to us is, whether it be ultimately evil. From the confessed and felt imperfection of our knowledge, we ought to presume, that there may be consequences of this economy which are hidden from us: from the benevolence which pervades the general designs of nature, we ought also to presume, that these consequences, if they could enter into our calculation, would turn the balance on the favorable side."
"These are the natures appropriated to the situation. Let [the wild beasts] enjoy their existence; let them have their country. Surface enough will be left to man, though his numbers were increased a hundred fold, and left to him, where he might live exempt from these annoyances."
"Now, according to the established order of Nature, (which we must suppose to prevail, or we cannot reason at all upon the subject,) the three methods by which life is usually put an end to, are, acute diseases, decay, and violence. The simple and natural life of brutes is not often visited by acute distempers; nor could it be deemed an improvement of their lot, if it were. Lot it be considered, therefore, in what a condition of suffering and misery a brute animal is placed, which is left to perish by decay. In human sickness or infirmity, there is the assistance of man's rational fellow-creatures; if not to alleviate his pains, at least to minister to his necessities; and to supply thee of his own activity. A brute, in his wild and natural state, does every thing for himself. When his strength, therefore, or his speed, or his limbs, or his senses fail him, he is delivered over, either to absolute famine, or to the protracted wretchedness of a life slowly wasted, by the scarcity of food. Is it, then, to see the world filled with drooping, superannuated, half-starved, helpless, and unhelped animals, that you would alter the present system of pursuit and prey?"
"But then this superfecundity, though of great occasional use and importance, exceeds the ordinary capacity of nature to receive or support its progeny. All superabundance supposes destruction, or must destroy itself. Perhaps there is no species of terrestrial animals whatever, which would not overrun the earth, if it were permitted to multiply in perfect safety; or offish, which would not fill the ocean: at least, if any single species were left to their natural increase without disturbance or restraint, the food of other species would be exhausted by their maintenance. It is necessary, therefore, that the effects of such prolific faculties be curtailed. In conjunction with other checks and limits, all subservient to the same purpose, are the thinnings which take place among animals, by their action upon one another."
"[T]he system of destruction amongst animals holds an express relation to the system of fecundity; that they are parts indeed of one compensatory scheme; is, that in each species the fecundity bears a proportion to the smallness of the animal, to the weakness, to the shortness of its natural term of life, and to the danger and enemies by which it is surrounded. An elephant produces but one calf: a butterfly lays six hundred eggs. Birds of prey seldom produce more than two eggs: the sparrow tribe, and the duck tribe, frequently sit upon a dozen. In the rivers, we meet with a thousand minnows for one pike; in the sea, a million of herrings for a single shark. Compensation obtains throughout. Defencelessness and devastation are repaired by fecundity."
"[T]he subject ... of animals devouring one another, forms the chief, if not the only instance, in the works of the Deity, of an economy, stamped by marks of design, in which the character of utility can be called in question."
"It is easy to romanticise, say, tigers or lions and cats. We admire their magnificent beauty, strength and agility. But we would regard their notional human counterparts as wanton psychopaths of the worst kind."
"Much more seriously, in those traditional eco-systems that we chose to retain, millions of non-human animals will continue periodically to starve, die horribly of thirst and disease, or even get eaten alive. This is commonly viewed as "natural" and hence basically OK."
"If we already lived in a cruelty-free world, the notion of re-introducing suffering, exploitation and creatures eating each other would seem not so much frightful as unimaginable – no more seriously conceivable than reverting to surgery without anaesthesia today."
"Humans already massively intervene in Nature, whether through habitat destruction, captive breeding programs for big cats, "rewilding", etc. So the question is not whether humans should "interfere", but rather what ethical principles should govern our interventions."
"The irrationality of the "appeal to Nature" is illustrated by a simple thought-experiment. Imagine, fancifully, if starvation, disease, parasitism, disembowelling, asphyxiation and being eaten alive were not endemic to the living world — or such miseries have already been abolished and replaced by an earthly paradise. Would anyone propose there is ethical case for (re)introducing them? Even proposing such a thought-experiment can sound faintly ridiculous."
"More controversially, technology can accelerate the transition from harming to helping free-living sentient beings: mankind's fitfully expanding "circle of compassion". The civilising process needn't be species-specific but instead extend to free-living dwellers in tomorrow's wildlife parks. Every cubic metre of the biosphere will soon be computationally accessible to surveillance, micro-management and control. Fertility regulation via immunocontraception can replace Darwinian ecosystems governed by starvation and predation. Any species of obligate carnivore we choose to preserve can be genetically and behaviourally tweaked into harmlessness. Asphyxiation, disembowelling, and agonies of being eaten alive can pass into the dustbin of history."
"Sound good? Nice parrots. However, they are merely postponing the point at which the red teeth and claws come into the picture. These parrot parents produce more than two offspring. What do you think happens to most of them? They go off and found happy egalitarian parrot families of their own? Maybe for a little while. But a species can't expand indefinitely. Most of these new parrots will get eaten or starve to death. The lucky few will go on to put dozens of new parrots into the world, for natural selection to claw apart and eat alive. r is evil, but K is not so great either."
"The moralistic fallacy is that what is good is found in nature. It lies behind the bad science in nature-documentary voiceovers: lions are mercy-killers of the weak and sick, mice feel no pain when cats eat them, dung beetles recycle dung to benefit the ecosystem and so on."
"On top of all the miseries inflicted by predators and parasites, the members of a species show no pity to their own kind. Infanticide, siblicide, and rape can be observed in many kinds of animals; infidelity is common even in so-called pair-bonded species; cannibalism can be expected in all species that are not strict vegetarians; death from fighting is more common in most animal species than it is in the most violent American cities ... Perhaps biology would have been able to mature more rapidly in a culture not dominated by Judeo-Christian theology and the Romantic tradition. It might have been well served by the First Holy Truth from [Buddha's] Sermon at Benares: "Birth is painful, old age is painful, sickness is painful, death is painful..." As soon as we recognize that there is nothing morally commendable about the products of evolution, we can describe human psychology honestly, without the fear that identifying a "natural" trait is the same as condoning it. As Katharine Hepburn says to Humphrey Bogart in The African Queen, "Nature, Mr. Allnut, is what we are put in this world to rise above.""
"I was walking along the bank of a stream when I saw a mother otter with her cubs, a very endearing sight, I'm sure you'll agree. And even as I watched, the mother otter dived into the water and came up with a plump salmon, which she subdued and dragged onto a half submerged log. As she ate it, while of course it was still alive, the body split and I remember to this day the sweet pinkness of its roes as they spilled out, much to the delight of the baby otters, who scrambled over themselves to feed on the delicacy. One of nature's wonders, gentlemen. Mother and children dining upon mother and children. And that is when I first learned about evil. It is built into the very nature of the universe. Every world spins in pain. If there is any kind of supreme being, I told myself, it is up to all of us to become his moral superior."
"Nature, it is urged, is cruel, and careless of the happiness of her millions of subjects. The woods where the poet found refreshment are a battlefield and a slaughter-house for other creatures. [That] pain and fear and bloodshed are a part of the law of life."
"The suffering and death I saw seemed to me in some meaningful respect lamentable—that is, unfortunate, regrettable, worthy of sadness, the kind of thing it would be better if the world did not involve. What can be said for such a response, and what against it? Can my lamentation be rationally defended as appropriate, or must it be viewed as nothing more than mawkish sentimentalism? How should we view the fact that some animals need to kill other animals in order to live? Can a world in which animals did not kill each other, and indeed did not need to do so in order to live, plausibly be called a better one?"
"The great outer oceans teem with fish, reptiles, turtles, shellfish, worms and other creatures, as numerous as the grains of malt in the bottom of a beer-barrel. There are serpents and monsters so big that their bodies can wind many times around Mount Meru. Other creatures are as small as particles of dust or the tip of a needle. They all undergo immense sufferings. The bigger ones swallow up the smaller ones. The small ones burrow into the big ones and eat them alive in their turn. The big animals all have many tiny ones living inside them, feeding on their flesh. Some of these creatures are born between the continents, where the sun does not shine and where they cannot even see whether their limbs are bent in or stretched out. Stupid and ignorant, they have no comprehension of what to do and what not to do. They are reborn in places where suffering knows no bounds."
"The wild animals that share our human world, in particular, live in constant fear. They cannot eat a single mouthful of food without being on their guard. They have many mortal enemies, for all animals prey on each other and there are always hunters, beasts of prey and other threats to life. Hawks kill small birds, small birds kill insects, and so on, continually amassing evil actions in an endless round of killing and being killed."
"In our guardianship of the rights of animals, must we not protect the weak among them against the strong? Must we not put to death blackbirds and thrushes because they feed on worms, or (if capital punishment offends our humanitarianism) starve them slowly by permanent captivity and vegetarian diet? What becomes of the 'return to nature' if we must prevent the cat's nocturnal wanderings, lest she should wickedly slay a mouse? Are we not to vindicate the rights of the persecuted prey of the stronger? Or is our declaration of the rights of every creeping thing to remain a mere hypocritical formula to gratify pug-loving sentimentalists."
"When we try to use psychologically based ethics to protect the flora or even the insentient fauna, to protect endangered species or ecosystems, we can only stammer. Wild nature is prolific, but not very compassionate, and what does it mean to respect life at the same time that we value natural processes? A bison fell through the ice into a river in Yellowstone Park; the environmental ethics there, letting nature take its course, forbade would-be rescuers from either saving or mercy killing the suffering animal. When the bighorn sheep of Yellowstone caught pinkeye, were blinded, injured, and starving as a result, 300 bighorns perished, over half the herd. Wildlife veterinarians wanted to treat the disease, but the Yellowstone ethicists left them to suffer, seemingly not respecting their life. Had they no mercy? No respect for life?"
"A drowning human would have been saved at once, a child with pinkeye given medical treatment. A simple ethics by extension seems too nondiscriminating; we cannot separate an ethics for humans from an ethics for wildlife."
"The Yellowstone ethicists let the bison drown, callous to its suffering; they let the blinded bighorns die. But in the spring of 1984 a sow grizzly and her three cubs walked across the ice of Yellowstone Lake to Frank Island, two miles from shore. They stayed several days to feast on two elk carcasses, when the ice bridge melted. Soon afterward, they were starving on an island too small to support them. This time the Yellowstone ethicists promptly rescued the grizzlies and released them on the mainland, in order to protect an endangered species. They were not rescuing individual bears so much as saving the species."
"Letting nature take its ecosystemic course is why the Yellowstone ethic forbade rescuing the drowning bison, but rescued the sow grizzly with her cubs, the latter to insure that the big predators remain. After the bison drowned, coyotes and magpies, foxes and ravens fed on the carcass. Later, even a grizzly bear fed on it. All this is a good thing because the system cycles on, and the great bear, like the wolves, is a sparkling gem in the network. On that account rescuing the whales trapped in the winter ice seems less of a good thing, when we note that rescuers had to drive away polar bears that attempted to eat the dying whales."
"The national park ethic has concluded that a simple extension of compassion from human, and Christian, ethics to wildlife does not appreciate their wildness. Perhaps we are beginning to see the trouble with rescuing those whales. Or maybe we are carrying this let-nature take-its-course ethic to extremes. We are beginning to worship nature. Has ethics here somehow gone wild in the bad sense, blinded by a philosophy of false respect for cruel nature? Can this indifference be the right ethics for wild animals? Can it be godly to say, "Let them suffer!"?"
"The rescue of individual animals—a couple of whales, a bison, a few deer—is humane enough and does not seem to have any detrimental effects, but that may not be the end of moral considerations, which ought to act on principles that can be universalized. Perhaps it brings these duties into clearer focus to consider populations, herds with hundreds of animals."
"What we ought to do depends on what is. The is of nature differs significantly from the is of culture, even when similar suffering is present. A human being in a frozen river would be rescued at once; a human attacked by a wolverine would be flown by helicopter to the hospital. Bison and deer are not humans and we cannot give them identical treatment; still, if suffering is a bad thing for humans, who seek to eliminate it, why is suffering not also a bad thing for bison? We cannot give medical treatment to all wild animals; we should not interrupt a predator killing its prey. But when we happen upon an opportunity to rescue an animal with the pull of a rope, or mercy-kill it lest it suffer, why not? If we can treat a herd of blinded sheep, why not? If we can feed the deer, starving in the winter, why not? That seems to be what human nature urges, and why not let human nature take its course? That seems to be what Jesus urges, doing to others as you would have them do to you, and why not follow the golden rule?"
"[W]hether we look to animal pleasures or to animal pains, the result is alike just what we should expect to find on the supposition of these pleasures and pains having been due to necessary and physical, as distinguished from intelligent and moral, antecedents; for how different is that which is from that which might have been! Not only might beneficent selection have eliminated the countless species of parasites which now destroy the health and happiness of all the higher organisms; not only might survival of the fittest, in a moral sense, have determined that rapacious and carnivorous animals should yield their places in the world to harmless and gentle ones; not only might life have been without sickness and death without pain;—but how might the exigences and the welfare of species have been consulted by the structures and the habits of one another! But no! Amid all the millions of mechanisms and habits in organic nature, all of which are so beautifully adapted to the needs of the species presenting them, there is no single instance of any mechanism or habit occurring in one species for the exclusive benefit of another species—although, as we should expect on the non-theistic theory, there are some comparatively few cases of a mechanism or a habit which is of benefit to its possessor being also utilised by other species. Yet, on the beneficent-design theory, it is impossible to understand why, when all mechanisms and habits in the same species are invariably correlated for the benefit of that species, there should never be any such correlation between mechanisms and habits of different species. For how magnificent, how sublime a display of supreme beneficence would nature have afforded if all her sentient animals had been so inter-related as to minister to each other's happiness! Organic species might then have been likened to a countless multitude of voices, all singing to their Creator in one harmonious psalm of praise. But, as it is, we see no vestige of such correlation; every species is for itself, and for itself alone—an outcome of the always and everywhere fiercely raging struggle for life."
"Making lasting gifts for animals in our estate plans is perhaps the single most important thing we can do to ensure animals have the strongest possible voice for their protection."
"The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for whites or women for men."
"Hold then the same view of the dog which has lost his master, which has sought him in all the thoroughfares with cries of sorrow, which comes into the house troubled and restless, goes downstairs, goes upstairs; goes from room to room, finds at last in his study the master he loves, and betokens his gladness by soft whimpers, frisks, and caresses.There are barbarians who seize this dog, who so greatly surpasses man in fidelity and friendship, and nail him down to a table and dissect him alive, to show you the Mesaraic veins! You discover in him all the same organs of feeling as in yourself. Answer me, Mechanist, has Nature arranged all the springs of feeling in this animal to the end that he might not feel? Has he nerves that he may be incapable of suffering? Do not suppose that impertinent contradiction in Nature."
"How important it is, then, that the child be taught to govern its passions! How important that it be taught to be kind, gentle, loving, and humane; and in all the range of human thought there is not a better, wiser, or more expedient way of accomplishing this end than by teaching kindness towards God's lower creatures. If children are thus taught they will have instilled into their hearts those principles of action which will make them kind and merciful not only to the lower animals, but also toward their fellow-men as they attain to manhood. Let them be taught that the lower animals are God's creatures, as they themselves are, put here by a common Heavenly Father, each for its own special purpose, and that they have the same right to life and protection. Let them be taught that principle recognised by all noble-hearted men, that it is only a depraved, debased, and cowardly nature that will injure an inferior, defenceless creature, simply because it is in its power to do so, and that there is no better, no grander test of true bravery and nobility of character than one's treatment of the lower animals."
"The importance of animal suffering seems to be one significant lacuna in the ethical views of most elite thinkers. It's helpful to expand people's hearts and minds on this issue, although we need to make sure to do so in a way that actually helps suffering animals in nature rather than reinforcing some of the other ideas of the animal-rights movement, like that we should "leave animals alone in all cases.""
"A man can live and be healthy without killing animals for food; therefore, if he eats meat, he participates in taking animal life merely for the sake of his appetite. And to act so is immoral."
"No one has the right routinely to override anyone else's rights, including those of animals. One must act in everyone's best interests as much as possible. [...] [Since] the law most unequivocally accords rights to persons, and typically denies rights to nonpersons, then practically, there is an imperative to deem sentient animals to be persons."
"My own life has convinced me that the limitations most of us encounter in our relations with other animals reflect not their shortcomings, as we so often assume, but our own narrow views about who they are and the kinds of relationships we can have with them. And so I conclude by urging anyone with an interest in animal rights to open your heart to the animals around you and find out for yourself what it's like to befriend a nonhuman person."
"If a being suffers, there can be no moral justification for refusing to take that suffering into consideration. No matter what the nature of the being, the principle of equality requires that the suffering be counted equally with the like suffering – in so far as rough comparisons can be made – of any other being. If a being is not capable of suffering, or of experiencing enjoyment or happiness, there is nothing to be taken into account. This is why the limit of sentience (...) is the only defensible boundary of concern for the interests of others."
"The animals themselves are incapable of demanding their own liberation, or of protesting against their condition with votes, demonstrations, or bombs. Human beings have the power to continue to oppress other species forever, or until we make this planet unsuitable for living beings. Will our tyranny continue, proving that we really are the selfish tyrants that the most cynical of poets and philosophers have always said we are? Or will we rise to the challenge and prove our capacity for genuine altruism by ending our ruthless exploitation of the species in our power, not because we are forced to do so by rebels or terrorists, but because we recognize that our position is morally indefensible? The way in which we answer this question depends on the way in which each one of us, individually, answers it."
"As often as Herman had witnessed the slaughter of animals and fish, he always had the same thought: in their behaviour toward creatures, all men were Nazis. The smugness with which man could do with other species as he pleased exemplified the most extreme racist theories, the principle that might is right."
"The butchering of harmless animals cannot fail to produce much of that spirit of insane and hideous exultation in which news of a victory is related altho' purchased by the massacre of a hundred thousand men. If the use of animal food be, in consequence, subversive to the peace of human society, how unwarrantable is the injustice and barbarity which is exercised toward these miserable victims. They are called into existence by human artifice that they may drag out a short and miserable existence of slavery and disease, that their bodies may be mutilated, their social feelings outraged. It were much better that a sentient being should never have existed, than that it should have existed only to endure unmitigated misery."
"It is only by softening and disguising dead flesh by culinary preparation that it is rendered susceptible of mastication or digestion, and that the sight of its bloody juices and raw horror does not excite intolerable loathing and disgust."
"The thinking man must [...] oppose all cruel customs no matter how deeply rooted in tradition and surrounded by a halo. True manhood is too precious a spiritual good for us to surrender any part of it to thoughtlessness."
"Europeans are awakening more and more to a sense that beasts have rights, in proportion as the strange notion is being gradually overcome and outgrown, that the animal kingdom came into existence solely for the benefit and pleasure of man. This view, with the corollary that non-human living creatures are to be regarded merely as things, is at the root of the rough and altogether reckless treatment of them, which obtains in the West."
"It is asserted that beasts have no rights; the illusion is harboured that our conduct, so far as they are concerned, has no moral significance, or, as it is put in the language of these codes, that "there are no duties to be fulfilled towards animals." Such a view is one of revolting coarseness, a barbarism of the West, whose source is Judaism. In philosophy, however, it rests on the assumption, despite all evidence to the contrary, of the radical difference between man and beast,—a doctrine which, as is well known, was proclaimed with more trenchant emphasis by Descartes than by any one else: it was indeed the necessary consequence of his mistakes."
