Primates and Philosophers: How Morality Evolved

Editorial Reviews
From Publishers Weekly
Celebrated primatologist de Waal expands on his earlier work in Good Natured: The Origins of Right and Wrong in Humans and Other Animals to argue that human traits of fairness, reciprocity and altruism develop through natural selection. Based on his 2004 Tanner Lectures at Princeton, this book argues that our morality grows out of the social instincts we share with bonobos, chimpanzees and apes. De Waal criticizes what he calls the "veneer theory," which holds that human ethics is simply an overlay masking our "selfish and brutish nature." De Waal draws on his own work with primates to illustrate the evolution of morality. For example, chimpanzees are more favorably disposed to others who have performed a service for them (such as grooming) and more likely to share their food with these individuals. In three appendixes, de Waal ranges briefly over anthropomorphism, apes and a theory of mind, and animal rights. The volume also includes responses to de Waal by Robert Wright, Christine M. Korsgaard, Philip Kitcher and Peter Singer. Although E.O. Wilson and Robert Wright have long contended that altruism is a product of evolution, de Waal demonstrates through his empirical work with primates the evolutionary basis for ethics. (Oct.)

It was not until a year and a half after his voyage on board the Beagle that Charles Darwin first came face to face with an ape. He was standing by the giraffe house at the London Zoo on a warm day in late March of 1838. The zoo had just acquired an orangutan named Jenny. One of the keepers was teasing her—showing her an apple, refusing to hand it over. Poor Jenny "threw herself on her back, kicked & cried, precisely like a naughty child," Darwin wrote in a letter to his sister. In the secret notebooks that he kept after the voyage, Darwin was speculating about evolution from every angle, including the emotional, and he was fascinated by Jenny’s tantrum. What is it like to be an ape? Does an orangutan’s frustration feel a lot like ours? Might she cherish some sense of right and wrong? Will an ape despair because her keeper is breaking the rules—because he is just not playing fair? Our own species has been talking, volubly and passionately, for at least 50,000 years, and it’s a fair guess that arguments about right and wrong were prominent in our conversation pretty much from the beginning. We started writing things down 5,000 years ago, and some of our first texts were codes of ethics. Our innumerable volumes of scripture and law, our Departments of Justice, High Courts, Low Courts, and Courts of Common Pleas are unique in the living world. But did we human beings invent our feeling for justice, or is it part of the package of primal emotions that we inherited from our ancestors? In other words: Did morality evolve? Dutch-born psychologist, ethologist and primatologist Frans de Waal has spent his career watching the behavior of apes and monkeys, mostly captive troupes in zoos. As a young student, he sat on a wooden stool day after day for six years, observing a colony of chimpanzees at the Arnhem Zoo. Today he watches chimpanzees from an observation post at Emory University’s Yerkes National Primate Research Center in Atlanta and at other zoos and primate centers. His work, along with primatologist Jane Goodall’s, has helped lift Darwin’s conjectures about the evolution of morality to a new level. He has documented tens of thousands of instances of chimpanzee behavior that among ourselves we would call Machiavellian and about as many moments that we would call altruistic, even noble. In his scientific papers and popular books (including Chimpanzee Politics, Our Inner Ape and Good Natured), he argues that Darwin was correct from that first glimpse of Jenny at the zoo. Sympathy, empathy, right and wrong are feelings that we share with other animals; even the best part of human nature, the part that cares about ethics and justice, is also part of nature. De Waal’s latest book, Primates and Philosophers, is based on the Tanner Lectures that he delivered at Princeton University’s Center for Human Values in 2004. In this book he tries—as he has many times before—to refute a popular caricature of Darwinism. Many people assume that to be good, be nice, behave, play well with others, we have to rise above our animal nature. It’s a dog-eat dog world out there—or, as the Romans put it, homo homini lupus, man is wolf to man (a curious proverb for a people whose founding myth was the suckling by a wolf of the infant twins Romulus and Remus). Thomas Henry Huxley, Darwin’s self-appointed bulldog, promoted this dark, cold view of life in a famous lecture, Evolution and Ethics. "The ethical progress of society depends, not on imitating the cosmic process, still less in running away from it, but in combating it," he declared. In Fyodor Dostoyevsky’s The Brothers Karamazov, Ivan puts it another way: if there is no God, then we are lost in a moral chaos. "Everything is permitted." De Waal calls this "Veneer Theory." In this view, human morality is a thin crust on a churning urn of boiling funk. In reality, de Waal reminds us, dogs are social, wolves are social, chimps and macaques are social, and we ourselves are "social to the core." Goodness, generosity and genuine kindness come just as naturally to us as meaner feelings. We didn’t have to invent compassion. When our ancestors began writing down the first codes of conduct, precepts, laws and commandments, they were elaborating on feelings that evolved thousands or even millions of years before they were born. "Instead of empathy being an endpoint," de Waal writes, "it may have been the starting point." Back in the 1950s and 1960s, when animal psychologists talked about "sympathy" and "empathy," they always put those words between quotation marks, de Waal notes. Now he wants to take away the quotation marks. He describes one of his best-known demonstrations that animals care about fairness. In the experiment, he had pairs of capuchin monkeys perform simple tasks in their cages. For successfully completing each task they would get a reward, sometimes a slice of cucumber, sometimes a grape. All the monkeys would work for and eat the cucumber slices, but they preferred grapes. If one monkey kept getting paid in cucumber and it could see that its partner in the next cage was getting grapes, it would get mad, like Darwin’s Jenny. After a while the monkey would refuse to eat or throw the cucumber right out of the cage. Is de Waal right about all this? In the second half of Primates and Philosophers, his arguments are critiqued by a series of commentators, all of whom have written important studies of evolutionary ethics. They cite Freud, Kant, Hume, Nietzsche and Adam Smith. They circle and circle around those pairs of capuchin monkeys: "A capuchin rejects a cucumber when her partner is offered a grape—is she protesting the unfairness, or is she just holding out for a grape?" writes Christine M. Korsgaard, Arthur Kingsley Porter Professor of Philosophy at Harvard University. "Of course, if the lucky capuchin were to throw down the grape until his comrade had a similar reward, that would be very interesting!" writes Philip Kitcher, John Dewey Professor of Philosophy at Columbia University. They disagree, they discuss, they bicker a little, like all primates and philosophers. They illuminate not only ageless questions of ethics but also current concerns such as the Geneva convention and "why universal empathy is such a fragile proposal," as de Waal writes in his response to his critics. By the end of the book it seems clear that we can no longer look at morality as a sort of civilized veneer on a cold and selfish animal, even though that view goes back long before Darwin went to the zoo. Its origin lies in the Western concept of original sin—when Adam and Eve ate their first apple.

From Booklist
Primatologist de Waal's career has been devoted to demonstrating that nature isn't utterly red in tooth and claw. His Tanner Lectures in Human Values argue that for the great apes and humans, in particular, morality isn't a veneer masking self-interest. It is intrinsic, the evolutionary outcome of the fact that altruism is conducive to species survival. Darwin, who saw no "conflict between the harshness of the evolutionary process and the gentleness of some of its products" and who affirmed the developmental similarity of species, including humans, essentially held the same position, de Waal says, being influenced toward it by Scottish moral philosopher Adam Smith. There is more to de Waal's exceptionally rich but always lucid paper, notably including an appendix, one of three, on animal rights. Four philosophers--one the controversial ethicist and advocate for animals Peter Singer--critique aspects of de Waal's argument, and in conclusion, de Waal responds to them. Intellectual soul food for biology-minded ethicists, in particular. Ray Olson

Review
"Goodness, generosity and genuine kindness come just as naturally to us as meaner feelings. We didn't have to invent compassion." -- Jonathan Weiner, Scientific American

"Morality has been demystified. Wrested from the hands of philosophers, it has become an ordinary object of scientific inquiry." -- Oliver Curry, Times Higher Education Supplement

"Primates and Philosophers has the spontaneity of a good conversation." -- David Sloan Wilson, American Scientist

Review
Frans de Waal defends against philosopher critics his view that the roots of morality can be seen in the social behavior of monkeys and apes. . . . [H]e argues that human morality would be impossible without certain emotional buildings blocks that are clearly at work in chimps and monkey societies. . . . Dr. de Waal sees human morality as having grown out of primate sociality, but with two extra levels of sophistication. People enforce their society's moral codes much more rigorously with rewards, punishments and reputation building. They also apply a degree of judgment and reason, for which there are no parallels in animals.
(Nicholas Wade The New York Times )

De Waal is one of the world's foremost authorities on nonhuman primates, and his thoughtful contribution to Primates and Philosophers is enriched by decades of close observation of their behavior. . . . He argues that humans are like their closest evolutionary kin in being moral by nature. . . . [A]n impressively well-focused collection of essays.

(Ray Olsen Booklist )

In his new book, Primates and Philosophers, Frans de Waal argues that the origins of human goodness can be seen in apes and monkeys. He claims that we have evolved from a long line of social animals for whom close co-operation is 'not an option but a survival strategy'. Not only are we nice by nature, but our ancestors were too, ever since they came down from the proverbial trees.
(Stephen Cave Financial Times )

Frans de Waal, an acclaimed primatologist, has much to say about what he considers the biological origins of morality. Unlike many recent antireligion writers such as Richard Dawkins, Sam Harris, and Daniel Dennett, who use the latest socio-biological research to campaign against religion, de Waal has no antireligious agenda. This both keeps his writing more focused and helps him avoid many of the argumentative errors of Dawkins and company...De Waal is a keen social observer, but he focuses mostly on what we can learn from what he knows best-the study of primates, including the human variety.
(Joe Pettit Commonweal )

Review
Frans de Waal has achieved that state of grace for a scientist--doing research that is both rigorous and wildly creative, and in the process has redefined how we think about the most interesting realms of behavior among nonhuman primates--cooperation, reconciliation, a sense of fairness, and even the rudiments of morality. In these Tanner lectures and the subsequent dialogue with leading philosophers and evolutionary psychologists, de Waal takes this knowledge to redefine how we think of morality in another primate, namely ourselves. This is superb and greatly challenging thinking.
(Robert M. Sapolsky, author of "Why Zebras Don't Get Ulcers" and "A Primate's Memoir" )

Product Description

"It's the animal in us," we often hear when we've been bad. But why not when we're good? Primates and Philosophers tackles this question by exploring the biological foundations of one of humanity's most valued traits: morality.

In this provocative book, primatologist Frans de Waal argues that modern-day evolutionary biology takes far too dim a view of the natural world, emphasizing our "selfish" genes. Science has thus exacerbated our reciprocal habits of blaming nature when we act badly and labeling the good things we do as "humane." Seeking the origin of human morality not in evolution but in human culture, science insists that we are moral by choice, not by nature.

Citing remarkable evidence based on his extensive research of primate behavior, de Waal attacks "Veneer Theory," which posits morality as a thin overlay on an otherwise nasty nature. He explains how we evolved from a long line of animals that care for the weak and build cooperation with reciprocal transactions. Drawing on both Darwin and recent scientific advances, de Waal demonstrates a strong continuity between human and animal behavior. In the process, he also probes issues such as anthropomorphism and human responsibilities toward animals.

Based on the Tanner Lectures de Waal delivered at Princeton University's Center for Human Values in 2004, Primates and Philosophers includes responses by the philosophers Peter Singer, Christine M. Korsgaard, and Philip Kitcher and the science writer Robert Wright. They press de Waal to clarify the differences between humans and other animals, yielding a lively debate that will fascinate all those who wonder about the origins and reach of human goodness.

"Frans de Waal has achieved that state of grace for a scientist--doing research that is both rigorous and wildly creative, and in the process has redefined how we think about the most interesting realms of behavior among nonhuman primates--cooperation, reconciliation, a sense of fairness, and even the rudiments of morality.

This is superb and greatly challenging thinking."--Robert M. Sapolsky, author of Why Zebras Don't Get Ulcers and A Primate's Memoir

"On the basis of a fascinating and provocative account of the remarkable continuities between the social emotions of humans and of nonhuman primates, de Waal develops a compelling case--which moral philosophers would do well to take seriously--for the evolutionary roots of human morality. In addition, he and his commentators conduct an illuminating discussion of some fundamental methodological and ethical issues--such as whether it is necessarily illicit to characterize animal behavior 'anthropomorphically,' and whether it is reasonable to attribute 'rights' to animals. Anyone who is interested in these issues, and especially those interested in the sources of human morality, will find this book exceptionally challenging and worthwhile."--Harry Frankfurt, author of On Bullshit

"Frans de Waal is the perfect guide to the emerging data on moral-like behavior in animals. Strengthened by deep sensitivity to the complexity of social relations and by a strong defense of anthropomorphism, this book shows how evolutionary biology can contribute to moral philosophy not merely through general principles, but by specific phylogenetic comparisons. It is a major advance in the socialization of ethology."--Richard Wrangham, Harvard University, coauthor of Demonic Males: Apes and the Origins of Human Violence

"Here, Frans de Waal, the world's leading researcher on primate behavior, a highly reflective thinker, and a skilled writer, presents the fruits of thirty years of empirical research. Addressing some of the most fundamental issues of social science and moral theory, he and the commentators produce a book that will be of deep and enduring interest to philosophers, social and political theorists, and anyone who wishes to assess their views about human nature and the nature of morality."--John Gray, London School of Economics, author of Straw Dogs: Thoughts on Humans and Other Animals

"This important book centers on Frans de Waal's powerful statement about the psychological nature of moral behavior, which involves strong continuities between humans and apes."--Christopher Boehm, University of Southern California, author of Hierarchy in the Forest
