This paper considers whether the available evidence from archeology, biological anthropology, primatology, and comparative gene-sequencing, can test evolutionary game theory models of cooperation as historical hypotheses about the actual course of human prehistory. The examination proceeds on the assumption that cooperation is the product of cultural selection and is not a genetically encoded trait. Nevertheless, we conclude that gene sequence data may yet shed signi cant light on the evolution of cooperation.

I argue that analyses of various kinds of cooperation will benefit from an account of the cognitive and communicative functions required for the cooperation. In particular, I focus on the role of intersubjectivity , which has not been sufficiently considered in game theory. Intersubjectivity will here be divided into representing the emotions, desires, attention, intentions, and beliefs of others. I then analyze some kinds of cooperation—reciprocal altruism, indirect reciprocity, cooperation on future goals, and (...) conventions—with respect to their cognitive and communicative prerequisites. It is argued that uniquely human forms of cooperation depend on advanced forms of intersubjectivity. (shrink)

Rational choice theory enjoys unprecedented popularity and influence in the behavioral and social sciences, but it generates intractable problems when applied to socially interactive decisions. In individual decisions, instrumental rationality is defined in terms of expected utility maximization. This becomes problematic in interactive decisions, when individuals have only partial control over the outcomes, because expected utility maximization is undefined in the absence of assumptions about how the other participants will behave. Game theory therefore incorporates not only rationality (...) but also common knowledge assumptions, enabling players to anticipate their co-players' strategies. Under these assumptions, disparate anomalies emerge. Instrumental rationality, conventionally interpreted, fails to explain intuitively obvious features of human interaction, yields predictions starkly at variance with experimental findings, and breaks down completely in certain cases. In particular, focal point selection in pure coordination games is inexplicable, though it is easily achieved in practice; the intuitively compelling payoff-dominance principle lacks rational justification; rationality in social dilemmas is self-defeating; a key solution concept for cooperative coalition games is frequently inapplicable; and rational choice in certain sequential games generates contradictions. In experiments, human players behave more cooperatively and receive higher payoffs than strict rationality would permit. Orthodox conceptions of rationality are evidently internally deficient and inadequate for explaining human interaction. Psychological game theory, based on nonstandard assumptions, is required to solve these problems, and some suggestions along these lines have already been put forward. Key Words: backward induction; Centipede game; common knowledge; cooperation; epistemic reasoning; game theory; payoff dominance; pure coordination game; rational choice theory; social dilemma.

Evolutionarily-minded scholars working on the most puzzling aspects of human cooperation-one-shot, anonymous interactions among non-kin where reputational information is not available-can be roughly divided into two camps. In the first, researchers argue for the existence of evolved capacities for genuinely altruistic human cooperation, and in their models emphasize the role of intergroup competition and selection, as well as group norms and markers of membership that reduce intragroup variability. Researchers in the second camp explain cooperation in (...) terms of individual-level decision-making facilitated by evolved cognitive mechanisms associated with well-established self- and kin-maximization models, as well as by ‘misfires’ that may result from these mechanisms interacting with novel environments. This essay argues that the manner in which culture provides information that de-anonymizes intragroup strangers suggests that neither evolved capacities for genuine altruism nor widespread misfires are necessary to account for anonymous, one-shot cooperation. (shrink)

Human cooperation is held to be an evolutionary puzzle because people voluntarily engage in costly cooperation, and costly punishment of non-cooperators, even among anonymous strangers they will never meet again. The costs of such cooperation cannot be recovered through kin-selection, reciprocal altruism, indirect reciprocity, or costly signaling. A number of recent authors label this behavior ‘strong reciprocity’, and argue that it is: (a) a newly documented aspect of human nature, (b) adaptive, and (c) evolved by (...) group selection. We argue exactly the opposite; that the phenomenon is: (a) not new, (b) maladaptive, and (c) evolved by individual selection. In our perspective, the apparent puzzle disappears to reveal a biological and evolutionary logic to human cooperation. Group selection may play a role in theory, but it is neither necessary nor sufficient to explain human cooperation. Our alternative solution is simpler, makes fewer assumptions, and is more parsimonious with the empirical data. (shrink)

Fundamental aspects of human use of the environment can be explained by game theory. Game theory explains aggregate behaviour of the human species driven by perceived costs and benefits. In the 'game' of global environmental protection and conservation, the stakes are the living conditions of all species including the human race, and the playing field is our planet. The question is can we control humanity's hitherto endless appetite for resources before we irreparably (...) harm the global ecosystem and cause extinction of even more species? The central problem is that some proportion of the individuals or groups will behave selfishly. The inducement for using more than a fair share, or 'cheating', increases as that resource becomes rarer, thus the benefits of cheating increase. In addition, the total number of people is increasing, so the proportion of cheaters must decrease to even keep total resource use constant. Cost benefit analysis of the effect of regulation and incentives on potential cheaters may provide a rational approach to controlling environmental problems. While it is debatable that environmental values are constant across cultures, communal use of resources seems to follow global rules. Cooperative use and punishment of those who use more than their share appear to be ubiquitous in human societies. Schemes for controlling human impact on the global environment must take into consideration basic behaviours including development of social norms and the positive feedback created because resources become more valuable with increasing rarity leading to more incentive for consumption.

This paper provides strong evidence challenging the self-interest assumption that dominates the behavioral sciences and much evolutionary thinking. The evidence indicates that many people have a tendency to voluntarily cooperate, if treated fairly, and to punish noncooperators. We call this behavioral propensity “strong reciprocity” and show empirically that it can lead to almost universal cooperation in circumstances in which purely self-interested behavior would cause a complete breakdown of cooperation. In addition, we show that people are willing to punish (...) those who behaved unfairly towards a third person or who defected in a Prisoner’s Dilemma game with a third person. This suggests that strong reciprocity is a powerful device for the enforcement of social norms involving, for example, food sharing or collective action. Strong reciprocity cannot be rationalized as an adaptive trait by the leading evolutionary theories of human cooperation (in other words, kin selection, reciprocal altruism, indirect reciprocity, and costly signaling theory). However, multilevel selection theories of cultural evolution are consistent with strong reciprocity. (shrink)

I discuss the division of the soul in plato's "republic". i concentrate on the arguments and illustrative examples given in book iv, but i treat the descriptions of different types of person in viii-ix and elsewhere as further constituents of a single, coherent theory. on my interpretation plato distinguishes three basic kinds of motivation which he claims all human beings regularly experience in some degree. reason is itself the immediate source of certain desires. in addition, there are appetitive (...) and also--quite distinct from either of the other two--competitive motivations.

David Buss’s Sexual Strategies Theory is one of the major evolutionary psychological research programmes, but, as I try to show in this paper, its theoretical and empirical foundations cannot yet be seen to be fully compelling. This lack of cogency comes about due to Buss’s failure to attend to the interactive nature of his subject matter, which leads him to overlook two classic and well known issues of game theoretic and evolutionary biological analysis. Firstly, Buss pays insufficient attention (...) to the fact that, since mate choice is a cooperative decision, what is adaptive for the two sexes individually is irrelevant to the evolutionary explanation of our sexual strategies; instead, all that matters is what is adaptive given the choices made by the other sex. Secondly, Buss does not pay enough attention to the difference between polymorphic and monomorphic evolutionarily stable states in his attempt to empirically confirm his theory. Because of this, the data he presents and analyses are unable to show that natural selection is the most important element in the explanation of the origins of our sexual strategies. In this way, I try to make clear that, at least as things stand now, Buss has failed to provide compelling grounds for thinking that Sexual Strategies Theory can make a major contribution to human psychology.

Is capitalism inherently predatory? Must there be winners and losers? Is public interest outdated and free-riding rational? Is consumer choice the same as self-determination? Must bargainers abandon the no-harm principle? Prisoners of Reason recalls that classical liberal capitalism exalted the no-harm principle. Although imperfect and exclusionary, modern liberalism recognized individual human dignity alongside individuals' responsibility to respect others. Neoliberalism, by contrast, views life as ceaseless struggle. Agents vie for scarce resources in antagonistic competition in which every individual seeks dominance. (...) This political theory is codified in non-cooperative game theory; the neoliberal citizen and consumer is the strategic rational actor. Rational choice justifies ends irrespective of means. Money becomes the medium of all value. Solidarity and good will are invalidated. Relationships are conducted on a quid pro quo basis. However, agents can freely opt out of this cynical race to the bottom by embracing a more expansive range of coherent action. (shrink)

The created co-creator theology states that human beings have the purpose of creating the most wholesome future possible for our species and the global ecosystem. I evaluate the human aspect of this theology by asking whether it is possible for human beings to do this. Do we have sufficient knowledge? Can we be motivated to do what is necessary to create a wholesome future for ourselves and our planet? We do not at present have sufficient knowledge, but (...) there is reason to believe that with further scientific research we will be able to acquire it. The more difficult question is whether we can be motivated to cooperate on the scale necessary to fulfill this purpose. Evolutionary theories of human sociality, altruism, and cooperation are reviewed. I conclude that it is possible for human beings to fulfill the purpose defined for us by the created cocreator concept, but doing this will not be easy. (shrink)

It is a common complaint against moral philosophers that their abstract theorising bears little relation to the practical problems of everyday life. Professor Braithwaite believes that this criticism need not be inevitable. With the help of the Theory of Games he shows how arbitration is possible between two neighbours, a jazz trumpeter and a classical pianist, whose performances are a source of mutual discord. The solution of the problem in the lecture is geometrical, and is based on the formal (...) analogy between the logic of the situation and the geometry of a parabola. But an appendix provides the alternative algebraic treatment of a general two-person collaboration situation. (shrink)

"An important contribution to contemporary jurisprudential debate and to legal thought more generally, Just Interpretations is far ahead of currently available work."--Peter Goodrich, author of Oedipus Lex "I was struck repeatedly by the clarity of expression throughout the book.

Furthermore, his own theory is quite original and provocative."--Aviam Soifer, author of Law and the Company We Keep.

NEITHER in the scholarly nor in the philosophical literature on Aristotle does his account of friendship occupy a very prominent place. I suppose this is partly, though certainly not wholly, to be explained by the fact that the modern ethical theories with which Aristotle’s might demand comparison hardly make room for the discussion of any parallel phenomenon. Whatever else friendship is, it is, at least typically, a personal relationship freely, even spontaneously, entered into, and ethics, as modern theorists tend to (...) conceive it, deals rather with the ways in which people are required to regard, and behave toward, one another, than with the organization of their private affairs. To the extent, then, that one shares this modern outlook one will tend to neglect, or treat merely as an historical curiosity, Aristotle’s efforts to define friendship and to place it within the framework of human eudaimonia, the theory of which is central to moral philosophy as he understands it. Yet in the Nicomachean Ethics the two books on φιλία make up nearly a fifth of the whole, and this seems to me a fair measure of the importance of this subject to the complete understanding both of Aristotle’s overall moral theory and even of many of the more circumscribed topics to which so much scholarly and philosophical attention has been devoted. If, as I suggest, the failure of commentators to appreciate its importance is partly the effect of distortions produced by the moral outlook that has predominated in modern moral philosophy, the careful study of these books may help to free us from constricting prejudices and perhaps even make it possible to discover in Aristotle a plausible and suggestive alternative to the theories constructed on the narrower base characteristic of recent times.

‘Altruistic punishment’ (i.e., costly punishment that serves no instrumental goal for the punisher) could serve, as suggested by the pertinent experimental literature, as a powerful enforcer of social norms. This paper discusses foundations, extensions, and, in particular, limits and open questions of this concept-and it does so mostly based on experimental evidence provided by the author. Inter alia, the paper relates the (standard) literature on negative emotions as a trigger of second party punishment to more recent experimental findings on the (...) phenomenon of ‘spontaneous cooperation’ and ‘spontaneous punishment’ and demonstrates its (tight) emotional basis. Furthermore, the paper discusses the potential for free riding on altruistic punishment. While providing valuable insights into the understanding of social order, ‘altruistic punishment’ is thus not the golden keystone of social stability. (shrink)

This article explores the challenge of developing a feminist law reform proposal to decertify sex and gender based on research conducted for the ‘Future of Legal Gender' project. Locating the proposal to decertify within a do-it-yourself, prefigurative approach to law reform, the article asks: Can a law reform proposal be both instrumental and radical? Can a proposal take shape as a viable legislative text and as a more subversive intervention to unsettle and reimagine gender’s relationship to law? This article explores (...) this at two levels. First, it considers the ontological challenges of developing a controversial law reform proposal in terms of its realness (or fictiveness), contours, and temporality, turning to ‘slow law' as a credible way of approaching radical reform. Second, it explores the design-based challenges of legal prototyping—foregrounding questions of legitimacy, participation, and purpose, which arise in designing a decertification law. At the heart of this discussion is the relationship between representation and enactment—between what a proposal presents and what its presentation does and does not accomplish. (shrink)

This article considers what the implications of decertification would be for single-sex services such as domestic and sexual violence support. Some reform options attached to decertification could (re)allocate authority away from the state to organisations or individuals to determine gender criteria. What would the consequences of such re-allocation be in determining eligibility to receive or access services or excluding people on the basis of a characteristic protected under equality law? Engaging with this in the context of domestic and sexual violence (...) support service provision raises a number of questions. Firstly, does the existence of gender-based violence and/or of the effects it produces require a stable category in order to address them? What benefits may emerge from providing single-sex spaces that could not be replicated in other settings? And finally, what criteria of exclusion and inclusion are currently used to determine access to spaces beyond legal gender status? (shrink)

This paper is part of a broader project whose aim is to present a coherent unified approach to natural language dialogue semantics using tools from type theory. Here we explore aspects of our approach which relate to situation theory and situation semantics. We first point out a relationship between type theory and the Austinian notion of truth. We then consider how records in type theory might be used to represent situations and how dependent record types can (...) be used to model constraints on situations. We then sketch treatments of attitude phenomena for which Barwise and Perry proposed situation semantic analyses (perception complements, belief, the Pierre puzzle) as well as two other intensional phenomena (intensional verbs and intentional identity). Finally we give a characterisation of the type theory used and a small illustrative fragment of English. (shrink)

The ancient Stoics notoriously argued, with thoroughness and force, that all ordinary “emotions” (passions, mental affections: in Greek, pãyh) are thoroughly bad states of mind, not to be indulged in by anyone, under any circumstances: anger, resentment, gloating; pity, sympathy, grief; delight, glee, pleasure; impassioned love (i.e. ¶rvw), agitated desires of any kind, fear; disappointment, regret, all sorts of sorrow; hatred, contempt, schadenfreude. Early on in the history of Stoicism, however, apparently in order to avoid the objection that human (...) nature itself demands and indeed justifies—under certain circumstances at any rate—emotional attachments to or aversions from, and reactions to, some persons, things, and happenings, they introduced a theory of what came to be called eÈpãyeiai, good and acceptable ways of feeling or being affected. For short I will render these in English by “good feelings.”1 They divided these into three generic kinds, which they dubbed “joy” (xarã), “wish” (boÊlhsiw) and “caution” (eÈlãbeia). They ranged these alongside, and set them in sharp contrast to, three of the four highest genera into which they divided the normal human emotions: “pleasure” (≤donÆ), i.e., being pleased about something,2 “appetitive desire” (§piyuµ€a), and “fear” (fÒbow), respectively. The Stoics maintained that, though ordinary, familiar human emotions such as these last-named ones were always bad, the three sorts of “good feeling,” and their more specific variations (since these three are only the basic genera into which lots of other good ways of feeling will fall), were not merely free from the grounds of criticism on which ordinary emotions were rejected, and so were perfectly acceptable. The fully perfected human being (the “wise person”) would indeed regularly be subject to them.3 Their theory of the perfect human life did not, then, they could claim, require any outrageously unnatural demand, presumably unrealizable in any case, for a life completely without all feelings of involvement in the sweep and flow of life..

The identification and valorization of unacknowledged, feminized forms of economic productivity has been an important task for feminist theory. In this article, we expand and rethink existing definitions of labour, in order to recognize the essential economic role women play in the stem cell and regenerative medicine industries, new fields of biomedical research that are rapidly expanding throughout the world. Women constitute the primary tissue donors in the new stem cell industries, which require high volumes of human embryos, (...) oöcytes, foetal tissue and umbilical cord blood. Such material is generally given for free in the advanced industrial democracies, constituted as a surplus (‘spare’ embryos) or waste (umbilical cord ‘afterbirth’, cadaveric foetuses, poor quality oöcytes) whose generative powers should not be withheld from others. At the same time, among impoverished female populations in developing nations, such biological material is now often procured through frankly transactional relations, where women undertake risky procedures for small fees. In each case, female bodily productivity is mobilized to support bioeconomic research, yet the economic value involved in these relations is largely unacknowledged. In this article, we consider both the gift economy and the transactional economy for reproductive tissues as a form of labour. In order to fully conceptualize the specificities of feminized productivity in the bioeconomy, we distinguish between earlier feminist theories of reproductive labour and the emerging practices generated by stem cell research, which we term regenerative labour. We consider how historical transformations in the regulation of feminized labour and the technical repertoires of stem cell research renegotiate the productivity limits of female reproductive biology, opening it out to novel and profitable forms of surplus value and enrolling women in complex negotiations over their role in bioeconomic activity.

It has been suggested that the enterprise of developing mechanistic theories of the human cognitive architecture is flawed because the theories produced are not directly falsifiable. Newell attempted to sidestep this criticism by arguing for a Lakatosian model of scientific progress in which cognitive architectures should be understood as theories that develop over time. However, Newell's own candidate cognitive architecture adhered only loosely to Lakatosian principles. This paper reconsiders the role of falsification and the potential utility of Lakatosian principles (...) in the development of cognitive architectures. It is argued that a lack of direct falsifiability need not undermine the scientific development of a cognitive architecture if broadly Lakatosian principles are adopted. Moreover, it is demonstrated that the Lakatosian concepts of positive and negative heuristics for theory development and of general heuristic power offer methods for guiding the development of an architecture and for evaluating the contribution and potential of an architecture's research program.

Taking as its point of departure the place of the vegetal realm within Jane Campion’s filmmaking, this article attends to both living and artificial plants, homing in on the exquisitely crafted paper flowers of _The Power of the Dog_ to explore their entanglement with human power relations. Manmade flowers are clearly distinct from the flowers of the garden or the prairie, but in this Western, they form part of a broader floral aesthetic with their living kin. Drawing upon thought (...) that stems from actual plants (Deleuze and Guattari’s arboreal-rhizomatic thinking) and vegetal philosophy (Marder, Coccia), as well as parallel botany’s attention to the artificial (Lionni), I follow the fate of one paper flower as it intersects with the gendered history of artificial flower making and floral sexual symbolism. Thinking with this paper flower, I engage with theories that variously question binary power relations (Cixous, Barthes, Steinbock), reading these alongside scholarship on sex, gender, and masculinity in the Western (Neale, Mulvey, Bruzzi), and broaching the hierarchies of settler colonialism. The film’s floral aesthetic, I argue, challenges the either/or logic of male or female, masculine or feminine, and even though it cannot fully break away from the binaries it critiques, it is indebted to registering the importance of the nuance (Barthes) in the unthreading of power.

The politics of precarity have emerged on the contemporary scene of critical theory with great social force in recent years.

This article looks at the history of the stem cell as an experimental life-form and situates it within the context of biological theories of cellular ageing which emerged in the 1960s, under the banner of ‘biogerontology’. The field of biogerontology, I argue, is crucially concerned not only with the internal limits to a cell's lifespan, but also with the possibility of overcoming limits. Hence, the sense of ‘revolution’ that has surrounded the isolation of human embryonic stem cells. The article (...) goes on to situate the problematic of cellular ageing within the larger historical transition from Fordist to post-Fordist modes of production – a transition whose effects on the life sciences have been insufficiently theorized – and points to resonances between the concerns of biogerontology and an emerging political rhetoric on the crisis of ageing and limits to growth. Having surfaced in parallel with the neo-liberal euphoria of the 1990s, the field of regenerative medicine presents itself as a biomedical solution to the problem of limits to growth. What is at stake in the contemporary biosciences, I suggest, is not so much the mass commodification of life itself as its transformation into a source of speculative surplus value. (shrink)

Over the past few decades, philosophers of biology have debated the need for a revised evolutionary synthesis that could integrate the causal dynamics of singular organisms into mainstream biological theory. In this chapter I examine two synthesizing arguments (extension and accretion) by turning to a historical source that has recently caught the attention of philosophers on both sides of the debate: Immanuel Kant’s Critique of the Power of Judgment. I argue that accretionists and extenders both pick out one of (...) two key components in Kant’s account of teleological judgment, which, according to Kant, must be held together. By emphasizing one part of Kant’s account of teleological judgment at the expense of the other, both sides overlook the practical nature of his critique. Kant does not simply identify the conditions that render it necessary to judge some products of nature teleologically, I suggest, but also demonstrates the need for second-order analysis to define various domains of inquiry that arise in response to the explanatory demands of nature. The shared turn to Kant indicates that synthesizing arguments can be evaluated against their capacity to accommodate ongoing negotiation between the plurality of research aims in practice. I conclude that a deflationary version of the extension argument is best suited to the task. (shrink)

Reframes philosophical understanding of, and engagement with, tragedy. In The Tragedy of Philosophy Andrew Cooper challenges the prevailing idea of the death of tragedy, arguing that this assumption reflects a problematic view of both tragedy and philosophy—one that stifles the profound contribution that tragedy could provide to philosophy today. To build this case, Cooper presents a novel reading of Immanuel Kant’s Critique of Judgment. Although this text is normally understood as the final attempt to seal philosophy from the threat of (...) tragedy, Cooper argues that Kant’s project is rather a creative engagement with a tragedy that is specific to philosophy, namely, the inevitable failure of attempts to master nature through knowledge. Kant’s encounter with the tragedy of philosophy turns philosophy’s gaze from an exclusive focus on knowledge to matters of living well in a world that does not bend itself to our desires. Tracing the impact of Kant’s Critique of Judgment on some of the most famous theories of tragedy, including those of G. W. F. Hegel, Friedrich Nietzsche, Martin Heidegger, and Cornelius Castoriadis, Cooper demonstrates how these philosophers extend the project found in both Kant and the Greek tragedies: the attempt to grasp nature as a domain hospitable to human life.

A subtitle for this paper might have been ‘The ugly face ofVerstehen’, for it asks whether the theory ofVerstehenhas, to switch metaphors, ‘dirty hands’. By the theory ofVerstehen, I mean the constellation of concepts—life, experience, expression, interpretative understanding—which, according to Wilhelm Dilthey, are essential for the study of human affairs, thereby showing that ‘the methodology of the human studies[Geisteswissenschafteri]is … different from that of the physical sciences’ :1 for in the latter, these concepts have no similar (...) place. Even critics of Dilthey tend to agree that his heart, if not his head, was in the right place: thatVerstehenwas designed as an antidote to ‘dehumanizing’ attempts by positivists to reduce the categories used in explaining human behaviour to just those equally operative in the physical sciences. As Dilthey himself put it, ‘there is no real blood flowing in the veins’ of human beings as examined by the positivists and their precursors: they do not treat of ‘the whole man’. The idea ofVerstehen, it seems, is doubly humane: a humanizing approach to the humane studies. (shrink)

Ender's tortured conscience is an illustration of the moral importance of following principles of just war theory—the “unspoken rules of manly warfare”—and their apparent tension with the demands of war and survival. This chapter talks about the ethics of conflict in Ender's various games—his battles and wars. It asks, was justice served in the Third Invasion and destruction of the bugger worlds, the event that came to be called the xenocide. Ender's life is actually a testimony to the just (...) war axiom that all people desire peace. In the tradition of just war theory, there are five principles that lay out the requirements of jus ad bellum, or how to go to war in an ethical way. They include just cause, legitimate authority, right intention, probability of success, and last resort. Ender's strategy is always to use devastating force to incapacitate the enemy. (shrink)

We shall consider a formulation of generalised quantifiers using type theory with records (TTR). TTR follows closely the development of record types in Martin-L¨of or constructive type theory but differs in that the type theory is defined on a classical set theoretic basis. This means that the classical set-theoretic approach to generalised quantifiers can be imported into the type theoretic framework. The result is, I believe, equivalent to the proposal for dynamic generalised quantifiers in Chierchia (1995). The (...) use of dependent types provides us with an elegant approach to the formulation of dynamic quantifiers. We use a notion of hypothetical context which we have used elsewhere to give accounts of intentional identity, answers to questions and information state updates in dialogue management. We suggest that this points towards a general theory of hypothetical context in natural language. We suspect also that our analysis using records will support analyses of common noun phrase and verb-phrase anaphora and also facilitate representations which are underspecified with respect to quantifier scope, though we leave the investigation of this to future research.

Cognitive architectures - task-general theories of the structure and function of the complete cognitive system - are sometimes argued to be more akin to frameworks or belief systems than scientific theories. The argument stems from the apparent non-falsifiability of existing cognitive architectures. Newell was aware of this criticism and argued that architectures should be viewed not as theories subject to Popperian falsification, but rather as Lakatosian research programs based on cumulative growth. Newell's argument is undermined because he failed to demonstrate (...) that the development of Soar, his own candidate architecture, adhered to Lakatosian principles. This paper presents detailed case studies of the development of two cognitive architectures, Soar and ACT-R, from a Lakatosian perspective. It is demonstrated that both are broadly Lakatosian, but that in both cases there have been theoretical progressions that, according to Lakatosian criteria, are pseudo-scientific. Thus, Newell's defense of Soar as a scientific rather than pseudo-scientific theory is not supported in practice. The ACT series of architectures has fewer pseudo-scientific progressions than Soar, but it too is vulnerable to accusations of pseudo-science. From this analysis, it is argued that successive versions of theories of the human cognitive architecture must explicitly address five questions to maintain scientific credibility. (shrink)

One feature of the neo/liberal possessive self is the propertied character of certain beliefs: treated as belonging to those who hold them, recognized and supported in acting on the world, and protected. While an ownership paradigm predates anti-discrimination and human rights regimes, these regimes have consolidated and extended the propertied status of certain identity beliefs in ways that naturalize and siloize them. But if beliefs’ propertied character is politically problematic, can it be unsettled and reformed? This paper considers one (...) possible mode for doing so, namely play. Oftentimes, play works to secure and assert the propertied attachments people have to their beliefs; but some forms of play offer other possibilities. Focusing on the state as a complex site of play relations and encounters, this article explores how state play engages identity beliefs in a contemporary legal drama of colliding beliefs between conservative Christians and liberal gay equality advocates.

Abstract. Don Browning's career involved a deep exploration into the frequently hidden philosophical assumptions buried in various forms of psychotherapeutic healing. These healing methodologies were based on metaphors and metaphysical assumptions about both the meaning of human fulfillment and the ultimate context of our lives. All too easily, psychological theories put forward philosophical anthropologies while claiming to be operating within a modest, empirical approach. Browning does not fault or criticize these psychotherapeutic enterprises for making such claims because he thinks (...) these claims are implicit in all discussions of psychological health. But he does fault these methodologies for not being more forthcoming about their shift from a narrow empirical investigation to a broad-ranging philosophical and even quasireligious orientation. Browning can be described as a “horizon analyst” who constantly pulled back the curtains and helped us see the deeper symbols, images, and metaphysical assumptions behind our psychological investigations.

A study of the evolution of consciousness from the simplest organism, through the self-aware human being, to enlightenment. Viewing recent theories from a Buddhist standpoint, the book sees evolution as a process of perpetual self-transcendence.

This paper focuses on Mary Midgley's influential discussions, over more than thirty years, of the relationship between human beings and animals, in particular on her concern to ‘remove the barriers’ that stand in the way of proper understanding and treatment of animals. These barriers, she demonstrates, have been erected by animal science, epistemology and mainstream moral philosophy alike. In each case, she argues, our attitudes to animals are warped by approaches that are at once excessively abstract, over-theoretical and guilty (...) of a collective hubris on the part of humankind. In keeping with Midgley's own position, it is argued in this paper that, to remove these barriers, what is required is not yet another theory of how and why animals matter, but attention to actual engagements with animals and to the moral failings or vices that distort people's relationships with them.

I explore a connection between Robert Nozick's account of decision value/symbolic utility in The Nature of Rationality and F. P. Ramsey's discussion of ethically neutral propositions in his 1926 essay , a discussion that Brian Skyrms in Choice and Chance credits with disclosing deeper foundations for expected utility than the celebrated Theory of Games and Economic Behavior of von Neumann and Morgenstern. Ramsey's recognition of ethically non-neutral propositions is essential to his foundational work, and the similarity of these propositions (...) to symbolic utility helps make the case that the latter belongs to the apparatus that constructs expected utility, rather than being reducible to it or being part of a proposal that can be cheerfully ignored. I conclude that decision value replaces expected utility as the central idea in (normative) decision theory. Expected utility becomes an approximation that is good enough when symbolic utility is not at stake. (shrink)

This essay continues Kafka’s tale of a human being who metamorphoses into a beetle. The tale is developed in the light of some recent theory about personal identity and rational choice, particularly Robert Nozick’s Closest-Continuer theory and Mark Johnston’s Relativism about the self. These are potentially complementary conceptions of relativity about the self, Nozick’s focusing on the individual’s ‘metric’ as a criterion of personal continuity, Johnston’s on social standards. When the individually authentic determination about ‘closeness’ coincides with (...) the community’s standards for continuity, the two accounts are complementary. The tale concludes with reference to applying the concept of personal identity for branching selves in the Many-Worlds Interpretation of quantum mechanics. Application of the concept of personal identity in an MWI context implies that there is a bad end in store for us all, as David Lewis argued in his last essay. (shrink)

For the past two decades, the humanistic disciplines have been dominated by poststructuralist theories and, more recently, a not unrelated curricular philosophy best defined as hardline multiculturalism, much discussed and often misunderstood. When linked together, they form an internal contradiction that is the moral challenge of liberal education today. Traditional political alignments cannot explain current divisions among the humanities professoriate. Ideological quarrels only obscure a deeper moral debate between an ascendant poststructuralism and a resurgent liberal humanism. It is important to (...) reappropriate liberal humanism in an effort to revitalize humanistic inquiry and renew its place in creative public discourse, and check a danger posed by poststructuralism's fascination with power and epistemological relativism which threaten to erase the ethical border between education and indoctrination.

Economists interpret global environmental quality to be a pure public good. Each country should contribute to its provision. However, this is hard to achieve because each government is tempted to take a free ride on the other governments' efforts. Not only has this dilemma been analysed with game theoretical methods but game theory has also been used to think about how to make amends. This paper reviews the game theoretical discussion on how international policy frameworks may (...) be designed to improve the chances for international cooperation. It is also shown that the evaluation of alternative environmental policy instruments deviates from the standard environmental economics model if applied to the international arena. For the benefit of an interdisciplinary readership, the evolution of the debate on global environmental policy is related to the recent history of economic thought. This history is taken to be materialised in the writings of economics' Nobel Prize laureates. (shrink)

Does game theory—the mathematical theory of strategic interaction—provide genuine explanations of human behaviour? Can game theory be used in economic consultancy or other normative contexts? Explaining Games: The Epistemic Programme in Game Theory—the first monograph on the philosophy of game theory—is (...) an attempt to combine insights from epistemic logic and the philosophy of science to investigate the applicability of game theory in such fields as economics, philosophy and strategic consultancy. I prove new mathematical theorems about the beliefs, desires and rationality principles of individual human beings, and explore in detail the logical form of game theory as it is used in explanatory and normative contexts. I argue that game theory reduces to rational choice theory if used as an explanatory device, and that game theory is nonsensical if used as a normative device. A provocative account of the history of game theory reveals that this is not bad news for all of game theory, though. Two central research programmes in game theory tried to find the ultimate characterisation of strategic interaction between rational agents. Yet, while the Nash Equilibrium Refinement Programme has done badly thanks to such research habits as overmathematisation, model-tinkering and introversion, the Epistemic Programme, I argue, has been rather successful in achieving this aim. "The 'epistemic' approach to game theory has emerged over the past twenty-five years. What is this approach? How does it differ from the conventional equilibrium-based approach to game theory? What have been its strengths and weaknesses to date? To find out, read this comprehensive and excellently written account". Adam Brandenburger, J. P. Valles Professor of Business Economics and Strategy, Stern School of Business, New York University "Reading Boudewijn de Bruin's book should be rewarding both for game theorists interested in the conceptual foundations of their discipline and for philosophers who want to learn more about formal analysis of strategic interaction. It provides an in-depth logical study of the currently dominant epistemic approaches to non-cooperative games, with an eye both to the attractions and to the serious challenges facing the Epistemic Programme".

What motives underlie the ways humans interact socially? Are these the same for all societies? Are these part of our nature, or influenced by our environments?Over the last decade, research in experimental economics has emphatically falsified the textbook representation of Homo economicus. Literally hundreds of experiments suggest that people care not only about their own material payoffs, but also about such things as fairness, equity and reciprocity. However, this research left fundamental questions unanswered: Are such social preferences stable components of (...) human nature; or, are they modulated by economic, social and cultural environments? Until now, experimental research could not address this question because virtually all subjects had been university students, and while there are cultural differences among student populations throughout the world, these differences are small compared to the full range of human social and cultural environments. A vast amount of ethnographic and historical research suggests that people's motives are influenced by economic, social, and cultural environments, yet such methods can only yield circumstantial evidence about human motives. Combining ethnographic and experimental approaches to fill this gap, this book breaks new ground in reporting the results of a large cross-cultural study aimed at determining the sources of social preferences that underlie the diversity of human sociality. The same experiments which provided evidence for social preferences among university students were performed in fifteen small-scale societies exhibiting a wide variety of social, economic and cultural conditions by experienced field researchers who had also done long-term ethnographic field work in these societies. The findings of these experiments demonstrated that no society in which experimental behaviour is consistent with the canonical model of self-interest. Indeed, results showed that the variation in behaviour is far greater than previously thought, and that the differences between societies in market integration and the importance of cooperation explain a substantial portion of this variation, which individual-level economic and demographic variables could not. Finally, the extent to which experimental play mirrors patterns of interaction found in everyday life is traced.The book starts with a succinct but substantive introduction to the use of game theory as an analytical tool and its use in the social sciences for the rigorous testing of hypotheses about fundamental aspects of social behaviour outside artificially constructed laboratories. The results of the fifteen case studies are summarized in a suggestive chapter about the scope of the project. (shrink)

Game theory is central to modern understandings of how people deal with problems of coordination and cooperation. Yet, ironically, it cannot give a straightforward explanation of some of the simplest forms of human coordination and cooperation--most famously, that people can use the apparently arbitrary features of "focal points" to solve coordination problems, and that people sometimes cooperate in "prisoner's dilemmas." Addressing a wide readership of economists, sociologists, psychologists, and philosophers, Michael Bacharach here proposes a revision (...) of game theory that resolves these long-standing problems. In the classical tradition of game theory, Bacharach models human beings as rational actors, but he revises the standard definition of rationality to incorporate two major new ideas. He enlarges the model of a game so that it includes the ways agents describe to themselves their decision problems. And he allows the possibility that people reason as members of groups, each taking herself to have reason to perform her component of the combination of actions that best achieves the group's common goal. Bacharach shows that certain tendencies for individuals to engage in team reasoning are consistent with recent findings in social psychology and evolutionary biology. As the culmination of Bacharach's long-standing program of pathbreaking work on the foundations of game theory, this book has been eagerly awaited. Following Bacharach's premature death, Natalie Gold and Robert Sugden edited the unfinished work and added two substantial chapters that allow the book to be read as a coherent whole. (shrink)

Formal analyses of Pascal’s Wager have almost all been decision-theoretic, with a human as the sole decision-maker. This paper analyses Pascal’s Wager in a game-theoretic setting in which the deity whose existence the human is considering wagering on is also a decision-maker. There is an equilibrium in which the human chooses to wager that the deity exists and Pascal’s Wager thus operates, but also one in which the human does not wager. Thus, in (...) a game-theoretic setting, Pascal’s Wager is indeterminate: wagering and not wagering are both consistent with equilibrium behaviour. (shrink)
