The Expanding Circle: Ethics and Sociobiology is a 1981 book by Peter Singer bridging the topics of sociobiology and ethics.
The central tenet of the book is that over the course of human history, people have expanded the circle of beings whose interests they are willing to value similarly to their own. Originally that circle would have been self, family and tribe, but over time it grew to encompass all other humans. [1] [2] [3] In the book, Singer argues that the circle should be expanded to include most animals: [4]
The circle of altruism has broadened from the family and tribe to the nation and race, and we are beginning to recognize that our obligations extend to all human beings. The process should not stop there. In my earlier book, Animal Liberation , I showed that it is as arbitrary to restrict the principle of equal consideration of interests to our own species as it would be to restrict it to our own race. The only justifiable stopping place for the expansion of altruism is the point at which all whose welfare can be affected by our actions are included within the circle of altruism. This means that all beings with the capacity to feel pleasure or pain should be included; we can improve their welfare by increasing their pleasures and diminishing their pains. The expansion of the moral circle should therefore be pushed out until it includes most animals.
The Expanding Circle's longest chapter concerns the relationship between reason and ethics. [2] Singer discusses the relationship between biological capacity for altruism and morality. He argues that altruism, when directed to one's small circle of family, tribe or even nation, is not moral, but it becomes so when applied to wider circles. This happens because of human capacity for reason, which "generalizes or universalizes" our altruistic tendencies beyond groups we are biologically inclined to be altruistic to. As such, reason is not the opposite of emotions and instincts but instead builds on it. [5] Hence the book title, the "expanding circle", with the circle being our consideration of whom we can be altruistic to, and the reason for its expansion, reason – a product of both ethics and sociology. [2] [3]
One reviewer noted that the book is "a remarkable and worthwhile synthesis of the neo-Kantian ethics of the Harvard moral philosopher John Rawls and the sociobiology of Harvard's E. O. Wilson". [5] Singer's book was indeed seen as one of the responses to Wilson’s 1975 work, Sociobiology: The New Synthesis , which argued that understanding ethics can be reduced to understanding our sociobiological programming. [2] While Wilson's work was at first ignored by moral philosophers, generally seen as controversial and even described as "arrogant", Singer was one of the first moral philosophers to constructively engage with it, arguing that at least some of sociobiology's arguments in general and Wilson's arguments in particular are valuable for further development of our understanding of the field of ethics (also known as moral philosophy). [2] [6] [7]
A new edition, published in 2011, includes a new afterword by Singer. In it, the author discusses how recent progress in biology and genetics have influenced his thinking, and how it reinforces his original theory. [2]
Altruism is the principle and practice of concern for the well-being and/or happiness of other humans or animals above oneself. While objects of altruistic concern vary, it is an important moral value in many cultures and religions. It may be considered a synonym of selflessness, the opposite of selfishness.
In moral philosophy, consequentialism is a class of normative, teleological ethical theories that holds that the consequences of one's conduct are the ultimate basis for judgement about the rightness or wrongness of that conduct. Thus, from a consequentialist standpoint, a morally right act is one that will produce a good outcome. Consequentialism, along with eudaimonism, falls under the broader category of teleological ethics, a group of views which claim that the moral value of any act consists in its tendency to produce things of intrinsic value. Consequentialists hold in general that an act is right if and only if the act will produce, will probably produce, or is intended to produce, a greater balance of good over evil than any available alternative. Different consequentialist theories differ in how they define moral goods, with chief candidates including pleasure, the absence of pain, the satisfaction of one's preferences, and broader notions of the "general good".
In ethical philosophy, ethical egoism is the normative position that moral agents ought to act in their own self-interest. It differs from psychological egoism, which claims that people can only act in their self-interest. Ethical egoism also differs from rational egoism, which holds that it is rational to act in one's self-interest. Ethical egoism holds, therefore, that actions whose consequences will benefit the doer are ethical.
Psychological egoism is the view that humans are always motivated by self-interest and selfishness, even in what seem to be acts of altruism. It claims that, when people choose to help others, they do so ultimately because of the personal benefits that they themselves expect to obtain, directly or indirectly, from doing so.
Peter Albert David Singer is an Australian moral philosopher who is Emeritus Ira W. DeCamp Professor of Bioethics at Princeton University. Singer's work specialises in applied ethics, approaching the subject from a secular, utilitarian perspective. He wrote the book Animal Liberation (1975), in which he argues for vegetarianism, and the essay "Famine, Affluence, and Morality", which argues the moral imperative of donating to help the poor around the world. For most of his career, he was a preference utilitarian. He revealed in The Point of View of the Universe (2014), coauthored with Katarzyna de Lazari-Radek, that he had become a hedonistic utilitarian.
Sociobiology is a field of biology that aims to explain social behavior in terms of evolution. It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics. Within the study of human societies, sociobiology is closely allied to evolutionary anthropology, human behavioral ecology, evolutionary psychology, and sociology.
In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals. In other words, utilitarian ideas encourage actions that ensure the greatest good for the greatest number. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility thus:
That property in any object, whereby it tends to produce benefit, advantage, pleasure, good, or happiness ... [or] to prevent the happening of mischief, pain, evil, or unhappiness to the party whose interest is considered.
Thomas Nagel is an American philosopher. He is the University Professor of Philosophy and Law Emeritus at New York University, where he taught from 1980 until his retirement in 2016. His main areas of philosophical interest are political philosophy, ethics and philosophy of mind.
John Leslie Mackie was an Australian philosopher. He made significant contributions to ethics, the philosophy of religion, metaphysics, and the philosophy of language. Mackie had influential views on metaethics, including his defence of moral scepticism and his sophisticated defence of atheism. He wrote six books. His most widely known, Ethics: Inventing Right and Wrong (1977), opens by boldly stating, "There are no objective values." It goes on to argue that because of this, ethics must be invented rather than discovered.
Richard Mervyn Hare, usually cited as R. M. Hare, was a British moral philosopher who held the post of White's Professor of Moral Philosophy at the University of Oxford from 1966 until 1983. He subsequently taught for a number of years at the University of Florida. His meta-ethical theories were influential during the second half of the twentieth century.
Group selection is a proposed mechanism of evolution in which natural selection acts at the level of the group, instead of at the level of the individual or gene.
"Famine, Affluence, and Morality" is an essay written by Peter Singer in 1971 and published in Philosophy & Public Affairs in 1972. It argues that affluent persons are morally obligated to donate far more resources to humanitarian causes than is considered normal in Western cultures. The essay was inspired by the starvation of Bangladesh Liberation War refugees, and uses their situation as an example, although Singer's argument is general in scope and not limited to the example of Bangladesh. The essay is anthologized widely as an example of Western ethical thinking.
Sociobiology: The New Synthesis is a book by the biologist E. O. Wilson. It helped start the sociobiology debate, one of the great scientific controversies in biology of the 20th century and part of the wider debate about evolutionary psychology and the modern synthesis of evolutionary biology. Wilson popularized the term "sociobiology" as an attempt to explain the evolutionary mechanics behind social behaviour such as altruism, aggression, and the nurturing of the young. It formed a position within the long-running nature versus nurture debate. The fundamental principle guiding sociobiology is that an organism's evolutionary success is measured by the extent to which its genes are represented in the next generation.
Evolutionary ethics is a field of inquiry that explores how evolutionary theory might bear on our understanding of ethics or morality. The range of issues investigated by evolutionary ethics is quite broad. Supporters of evolutionary ethics have argued that it has important implications in the fields of descriptive ethics, normative ethics, and metaethics.
Effective altruism (EA) is a 21st-century philosophical and social movement that advocates impartially calculating benefits and prioritizing causes to provide the greatest good. It is motivated by "using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis". People who pursue the goals of effective altruism, who are sometimes called effective altruists, follow a variety of approaches proposed by the movement, such as donating to selected charities and choosing careers with the aim of maximizing positive impact. The movement has achieved significant popularity outside the academy, spurring the creation of university-based institutes, research centers, advisory organizations and charities, which, collectively, have donated several hundreds of millions of dollars.
Earning to give involves deliberately pursuing a high-earning career for the purpose of donating a significant portion of earned income, typically because of a desire to do effective altruism. Advocates of earning to give contend that maximizing the amount one can donate to charity is an important consideration for individuals when deciding what career to pursue.
William David MacAskill is a Scottish philosopher and author, as well as one of the originators of the effective altruism movement. He was a Research Fellow at the Global Priorities Institute at the University of Oxford, co-founded Giving What We Can, the Centre for Effective Altruism and 80,000 Hours, and is the author of Doing Good Better (2015) and What We Owe the Future (2022), and the co-author of Moral Uncertainty (2020).
The End of Animal Farming: How Scientists, Entrepreneurs, and Activists Are Building an Animal-Free Food System is a 2018 book by Jacy Reese that argues animal farming will end by the year 2100 based on effective altruism reasoning and social movement strategy.
Insects and human ethical obligations towards them have been discussed by a number of writers and figures throughout history, many of whom, arguing from a variety of different perspectives, have contended that there exists a moral obligation towards not harming or killing insects. According to generally accepted definitions in animal welfare and agricultural ethics, however, it is argued that individual insects do not have a "right to life".
Moral circle expansion is an increase over time in the number and type of entities given moral consideration. The general idea of moral inclusion was discussed by ancient philosophers and since the 19th century has inspired social movements related to human rights and animal rights. Especially in relation to animal rights, the philosopher Peter Singer has written about the subject since the 1970s, and since 2017 so has the think tank Sentience Institute, part of the 21st-century effective altruism movement. There is significant debate on whether humanity actually has an expanding moral circle, considering topics such as the lack of a uniform border of growing moral consideration and the disconnect between people's moral attitudes and their behavior. Research into the phenomenon is ongoing.
