Ethologists and others studying animal behavior in a spirit are in need of a descriptive language and method that are neither anachronistically bound by behaviorist scruples nor prematurely committed to particular Just such an interim descriptive method can be found in intentional system theory. The use of intentional system theory is illustrated with the case of the apparently communicative behavior of vervet monkeys. A way of using the theory to generate data - including usable, testable data - is sketched. The (...) underlying assumptions of this approach can be seen to ally it directly with theorizing in evolutionary biology, which has recently come under attack from Stephen Gould and Richard Lewontin, who castigate it as the Their arguments, which are strongly analogous to B. F, Skinner's arguments against point to certain pitfalls that attend the careless exercise of such thinking (and rival varieties of thinking as well), but do not constitute a fundamental objection to either adaptationist theorizing or its cousin, intentional system theory.

In this paper I argue that we can learn much about wild justice and the evolutionary origins of social morality – behaving fairly – by studying social play behavior in group-living animals, and that interdisciplinary cooperation will help immensely. In our efforts to learn more about the evolution of morality we need to broaden our comparative research to include animals other than non-human primates. If one is a good Darwinian, it is premature to claim that only humans can be empathic (...) and moral beings. By asking the question What is it like to be another animal? we can discover rules of engagement that guide animals in their social encounters. When I study dogs, for example, I try to be a dogocentrist and practice dogomorphism. My major arguments center on the following big questions: Can animals be moral beings or do they merely act as if they are? What are the evolutionary roots of cooperation, fairness, trust, forgiveness, and morality? What do animals do when they engage in social play? How do animals negotiate agreements to cooperate, to forgive, to behave fairly, to develop trust? Can animals forgive? Why cooperate and play fairly? Why did play evolve as it has? Does being fair mean being more fit – do individual variations in play influence an individual''s reproductive fitness, are more virtuous individuals more fit than less virtuous individuals? What is the taxonomic distribution of cognitive skills and emotional capacities necessary for individuals to be able to behave fairly, to empathize, to behave morally? Can we use information about moral behavior in animals to help us understand ourselves? I conclude that there is strong selection for cooperative fair play in which individuals establish and maintain a social contract to play because there are mutual benefits when individuals adopt this strategy and group stability may be also be fostered. Numerous mechanisms have evolved to facilitate the initiation and maintenance of social play to keep others engaged, so that agreeing to play fairly and the resulting benefits of doing so can be readily achieved. I also claim that the ability to make accurate predictions about what an individual is likely to do in a given social situation is a useful litmus test for explaining what might be happening in an individual''s brain during social encounters, and that intentional or representational explanations are often important for making these predictions.

Waal shows how ethical behavior is as much a matter of evolution as any other trait.

To what degree has biology influenced and shaped the development of moral systems? One way to determine the extent to which human moral systems might be the product of natural selection is to explore behaviour in other species that is analogous and perhaps homologous to our own. Many non-human primates, for example, have similar methods to humans for resolving, managing, and preventing conflicts of interests within their groups. Such methods, which include reciprocity and food sharing, reconciliation, consolation, conflict intervention, and (...) mediation, are the very building blocks of moral systems in that they are based on and facilitate cohesion among individuals and reflect a concerted effort by community members to find shared solutions to social conflict. Furthermore, these methods of resource distribution and conflict resolution often require or make use of capacities for empathy, sympathy, and sometimes even community concern. Non-human primates in societies in which such mechanisms are present may not be exactly moral beings, but they do show signs of a sense of social regularity that -- just like the norms and rules underlying human moral conduct -- promotes a mutually satisfactory modus vivendi.

In this ground-breaking book, a renowned bioethicist argues that the political left must radically revise its outdated view of human nature. He shows how the insights of modern evolutionary theory, particularly on the evolution of cooperation, can help the left attain its social and political goals. Singer explains why the left originally rejected Darwinian thought and why these reasons are no longer viable. He discusses how twentieth-century thinking has transformed our understanding of Darwinian evolution, showing that it is compatible with (...) cooperation as well as competition, and that the left can draw on this modern understanding to foster cooperation for socially desirable ends. A Darwinian left, says Singer, would still be on the side of the weak, poor, and oppressed, but it would have a better understanding of what social and economic changes would really work to benefit them. It would also work toward a higher moral status for nonhuman animals and a less anthropocentric view of our dominance over nature. (shrink)

This text argues that justice is a virtue which everyone shares - a function of personal character and not just of government or economic planning. It uses examples from Plato to Ivan Boesky, to document how we live and how we feel.

Four principal papers and a total of 43 peer commentaries on the evolutionary origins of morality. To what extent is human morality the outcome of a continuous development from motives, emotions and social behaviour found in nonhuman animals? Jerome Kagan, Hans Kummer, Peter Railton and others discuss the first principal paper by primatologists Jessica Flack and Frans de Waal. The second paper, by cultural anthropologist Christopher Boehm, synthesizes social science and biological evidence to support his theory of how our hominid (...) ancestors became moral. In the third paper philosopher Elliott Sober and evolutionary biologist David Sloan Wilson argue that an evolutionary understanding of human nature allows sacrifice for others and ultimate desires for another's good. Finally Brian Skyrms argues that game theory based on adaptive dynamics must join the social scientist's use of rational choice and classical game theory to explain cooperation. (shrink)

The 'Evolution of Cooperation' addresses a simple yet age-old question; If living things evolve through competition, how can cooperation ever emerge? Despite the abundant evidence of cooperation all around us, there existed no purely naturalistic answer to this question until 1979, when Robert Axelrod famously ran a computer tournament featuring a standard game-theory exercise called The Prisoner's Dilemma. To everyone's surprise, the program that won the tournament, named Tit for Tat, was not only the simplest but the most "cooperative" entrant. (...) This unexpected victory proved that cooperation - one might even say altruism - is mathematically possible and therefore needs no hidden hand or divine agent to create and sustain it. A great roadblock to the understanding of all sorts of behavior was at last removed. The updated edition includes an extensive new chapter on cooperation in cancer cells and among terrorist organizations. (shrink)

The heart of this book is the reciprocal relationship between philosophical theories of mind and empirical studies of animal cognition.

The hypothesis of group selection fell victim to a seemingly devastating critique in 1960s evolutionary biology. In Unto Others (1998), we argue to the contrary, that group selection is a conceptually coherent and empirically well documented cause of evolution. We suggest, in addition, that it has been especially important in human evolution. In the second part of Unto Others, we consider the issue of psychological egoism and altruism -- do human beings have ultimate motives concerning the well-being of others? We (...) argue that previous psychological and philosophical work on this question has been inconclusive. We propose an evolutionary argument for the claim that human beings have altruistic ultimate motives. (shrink)

Flack and de Waal present evidence for behaviour in non-human primates that functions to share food, terminate fights and reconcile opponents. Consolation and punishment are also suggested. These functions are assumed to be the motivation for the behaviour. Animals indeed have expectations about signal meaning and the likely immediate consequences of their behaviour. This does not mean they understand genetic fitness, peacekeeping or justice, even if these functions are achieved. Instrumental aggression is used to achieve a goal, not to punish (...) wrong doers. More elaborate motivation would indeed require empathy, sympathy, community solutions and morality. Although more parsimonious explanations for the behaviour described are rejected as not necessarily being true, less parsimonious explanations are not necessarily true either, no matter how appealing.

In this article I draw on personal experience to explore the kinds of relationships that can develop between human and nonhuman animals. The first part of the article describes my encounters with wild baboons, whom I studied in East Africa over the course of many years. The baboons treated me as a social being, and to gain their trust I had to learn the troop's social conventions and behave in accordance with them. This process gave me a feeling for what (...) it means to be a baboon. Over time, I developed a sense of belonging to their community, and my subjective identity seemed to merge with theirs. This experience expanded my sense of the possible in interspecies relations. The second part of the article describes a mutual exploration of such possibilities in my relationship with my dog, Safi. I describe how Safi and I co-create systems of communication and emotional expression that permit deep 'intersubjectivity', despite our very different biological natures. In my relationships with baboons, dogs, and other animals, I have encountered the presence in another of something resembling a human 'self'. I emphasize the importance of recognizing and honoring this presence in other animals as well as in humans. (shrink)

Game theory based on rational choice is compared with game theory based on evolutionary, or other adaptive, dynamics. The Nash equilibrium concept has a central role to play in both theories, even though one makes extremely strong assumptions about cognitive capacities and common knowledge of the players, and the other does not. Nevertheless, there are also important differences between the two theories. These differences are illustrated in a number of games that model types of interaction that are key ingredients for (...) any theory of the social contract. (shrink)
