“The Bloggs Cases” Scarce drug case: You are an emergency room physician, and you only have five doses of a certain drug left. Alas, you have six patients who need it. Bloggs has a very severe version of the condition for which the drug is a treatment, and it will take all five doses of the drug to cure him. Your other five patients have mild versions of the condition, and each of them will be cured by a single dose. Any one of the six who doesn’t get the full dosage they need will die. What would be the right thing to do? A. Give all five doses to Bloggs. B. Give one dose to each of the other five.

“The Bloggs Cases” Transplant case: Suppose that you are a famous transplant surgeon, and that your transplants always work. You have five patients, each of whom needs a transplant. One needs a heart, one a lung, one a liver, and two need one kidney apiece. One of your patients, Bloggs, has come in today to find out the results from some lab work. You know from the results of the lab work that Bloggs would be a perfect donor for each of your five other patients, and you know that there are no other available donors. So you ask Bloggs if he would be willing to be cut up and have his organs distributed. He declines your kind offer, but you realize that you could easily overpower Bloggs and cut him up without his consent, and that no one would find out. What would be the right thing to do? A. Don’t overpower Bloggs and let the others die. B. Overpower Bloggs and transplant to the other five.

“The Bloggs Cases” What’s the difference? Scarce drug case Transplant case (Either 5 die or 1 dies) (Either 5 die or 1 dies)

What this lecture will do Note the variety of reasons people give for worrying about how we treat animals Discuss the distinction between animal welfare and animal rights Describe key underlying moral philosophies

What reasons do people give for worrying about how we treat animals? “People care about how animals are treated.” “The law (or my profession) requires certain treatment.” “A healthy animal is a productive one.” “Animals are sentient (feeling) organisms.” “Animals have rights.”

Some related moral philosophies Virtue theory: “Good people treat animals well.” Ethics of care: “There are professional/legal requirements regarding them.” Utilitarianism: “Maximize aggregate happiness.” Rights views: “Individuals have moral ‘trump cards’ against utilitarian arguments.”

Some related moral philosophies Virtue theory: “Good people treat animals well.” Ethics of care: “There are professional/legal requirements regarding them.” Utilitarianism: “Maximize aggregate happiness.” Rights views: “Individuals have moral ‘trump cards’ against utilitarian arguments.” Utilitarianism and rights views get a lot of attention because they are related to the distinction between “animal welfare” and “animal rights.”

What is the distinction? Animal welfarists Animal rightists

A popular/political conception of the distinction Animal welfarists Moderate/reasonable Revisionist Work within the system Calm/reasoning Well informed Scientists using animals as research subjects Animal rightists Radical/extreme Abolitionist Advocate violence, liberation Emotional/unreasoning Uninformed Animal activists

How philosophers conceive of the distinction Animal welfarists Utilitarian thinking Focus on maximizing aggregate happiness Animal rightists Rights-based thinking Focus on the individual’s rights

How philosophers conceive of the distinction Animal welfarists Utilitarian thinking Focus on maximizing aggregate happiness Animal rightists Rights-based thinking Focus on the individual’s rights Each view grows out of a major tradition in moral philosophy. Various philosophers have written carefully reasoned discussions of each view.

What reasons do people give for worrying about how we treat animals? “People care about how animals are treated.” “The law (or my profession) requires certain treatment.” “A healthy animal is a productive one.” “Animals are sentient (feeling) organisms.” “Animals have rights.” Utilitarianism’s focus on maximizing aggregate happiness focuses attention on the suffering of animals.

Peter Singer’s utilitarian view “All Animals Are Equal” is Singer’s most widely reprinted essay and chapter one of Animal Liberation (1975). Note that in this book that was targeted at a general sudience, Singer did not explicitly invoke utilitarian moral reasoning. But Singer in his professional philosophical writings, Singer is a proponent of one kind of utilitarianism. (There are a number of varieties of utilitarianism.)

Peter Singer’s utilitarian view Singer argues that our ideal of “moral equality” requires equal consideration of the interests of all affected. He argues that “sentience” (the capacity to experience suffering and/or enjoyment) is necessary and sufficient for having interests. Singer says that many non-human animals are capable of suffering physical or psychological pain. He concludes that all sentient animals deserve equal consideration of their interests. Singer also argues that if we gave equal consideration to animals’ interests, we would stop using animals in ways that we wouldn’t use our fellow human beings. On that basis, he argues for the abolition of animal agriculture, scientific research on animals, and sport hunting.

Peter Singer’s utilitarian view Singer’s use of the term “speciesism” made the word famous. He defines it as “a prejudice or attitude of bias in favor of the interests of members of one’s own species and against those of members of other species.” He compares it to racism and sexism, because each involves ignoring or differentially weighting the interests of members of other groups. He argues that speciesism is reinforced by ignoring relevant comparisons between species (e.g. behavior, neurophysiology, and evolutionary continuities).

Peter Singer’s utilitarian view But utilitarian arguments have been used to defend some of the same practices that Singer opposes. For instance: Some argue that animals’ happiness is a simpler thing than humans’ happiness, and that therefore using them in certain ways can be justified, even though using humans the same ways would not be justified. For instance, some argue that medical research on animals is justified by the improvements in human and animal welfare that result. And some argue that humanely raised and slaughtered farm animals add to the world’s happiness.

What reasons do people give for worrying about how we treat animals? “People care about how animals are treated.” “The law (or my profession) requires certain treatment.” “A healthy animal is a productive one.” “Animals are sentient (feeling) organisms.” “Animals have rights.” If animals have rights, then they may be due something more than “humane” treatment.

Tom Regan’s rights view Regan’s The Case for Animal Rights (1983) makes a sophisticated argument for extending moral rights to some animals.

Tom Regan’s rights view Regan argues that widely shared beliefs about human rights rationally require us to extend moral rights to some non-human animals. He conceives of moral rights as “trump cards” against utilitarian arguments. Most people believe that humans have some rights in this sense, including humans who are profoundly cognitively impaired. What grounds the attribution of such rights to both normal humans and the profoundly cognitively impaired, Regan argues, is that all of them are “subjects of a life,” that is, they all have a psychological life that goes better or worse for them. “[Some nonhuman animals possess] beliefs and desires, perceptions and memory, and a sense of the future, including their own future; an emotional life together with feelings of pleasure and pain, preference and welfare interests; an ability to initiate actions in pursuit of their desires and goals; a psychophysical identity over time; and an individual welfare in the sense that their experiential life fares well or ill for them, logically independent of their utility for others… and of their being the object of anyone’s else’s interest.” (Regan, 1983)

Tom Regan’s rights view But then, Regan argues, consistency requires us to attribute moral rights to any non-human animals that are similar “subjects of a life.” Regan argues that a range of animals qualify, including at least all normal, adult mammals and birds. If these animals have moral rights, however, then they “have trump cards” against the utilitarian arguments that are commonly used to justify things like agriculture and medical research. And if we wouldn’t accept a utilitarian justification for using cognitively impaired humans for agriculture and medical research, then we shouldn’t accept that justification in the case of these animals.

Animal welfare Animal rights Philosophically, these represent two important ways of thinking about ethics: Animal welfare Utilitarian thinking Focus on maximizing aggregate happiness Utilitarian thinking may leave room for various traditional uses of animals, with a focus on welfare-improving reforms. Animal rights Rights-based thinking Focus on the individual’s rights Attributing rights as “trump cards” against utilitarian arguments may call for an end to some traditional uses of animals.

What reasons do people give for worrying about how we treat animals? “People care about how animals are treated.” “The law (or my profession) requires certain treatment.” “A healthy animal is a productive one.” “Animals are sentient (feeling) organisms.” “Animals have rights.” Utilitarianism and rights views receive the most discussion, but there are ethicists working in other ethical traditions.

What reasons do people give for worrying about how we treat animals? Other traditions in ethical theory include: Virtue theory Ethics of Care Contractualism Theology-based ethics Dominionist views
