Computability theory concerns information with a causal–typically algorithmic–structure. As such, it provides a schematic analysis of many naturally occurring situations. Emil Post was the first to focus on the close relationship between information, coded as real numbers, and its algorithmic infrastructure. Having characterised the close connection between the quantifier type of a real and the Turing jump operation, he looked for more subtle ways in which information entails a particular causal context. Specifically, he wanted to find simple relations on reals (...) which produced richness of local computability-theoretic structure. To this extent, he was not just interested in causal structure as an abstraction, but in the way in which this structure emerges in natural contexts. Post’s programme was the genesis of a more far reaching research project. In this article we will firstly review the history of Post’s programme, and look at two interesting developments of Post’s approach. The first of these developments concerns the extension of the core programme, initially restricted to the Turing structure of the computably enumerable sets of natural numbers, to the Ershov hierarchy of sets. The second looks at how new types of information coming from the recent growth of research into randomness, and the revealing of unexpected new computability-theoretic infrastructure. We will conclude by viewing Post’s programme from a more general perspective. We will look at how algorithmic structure does not just emerge mathematically from information, but how that emergent structure can model the emergence of very basic aspects of the real world.

In this article, I compare and evaluate R. D. Laing and A. Esterson’s account of schizophrenia as developed in Sanity, Madness and the Family, social models of disability, and accounts of extended mental disorder. These accounts claim that some putative disorders should not be thought of as reflecting biological or psychological dysfunction within the afflicted individual, but instead as external problems. In this article, I consider the grounds on which such claims might be supported. I argue that problems should (...) not be located within an individual putative patient in cases where there is some acceptable test environment in which there is no problem. A number of cases where such an argument can show that there is no internal disorder are discussed. I argue, however, that Laing and Esterson’s argument—that schizophrenia is not within diagnosed patients—does not work. The problem with their argument is that they fail to show that the diagnosed women in their study function adequately in any environment. (shrink)

In this paper I extend the case for a necessitation account of particular laws in Kant's philosophy of science by examining the relation between reason's hypothetical use in the Appendix to the Transcendental Dialectic and the legitimate hypotheses identified in the Doctrine of Method. Building on normative accounts of reason's ideas, I argue that reason's hypothetical use does not describe the connections between objects and their grounds, which lie beyond the reach of the understanding, but merely prescribes the relations between (...) appearances and their conditions, for which the understanding must seek. A legitimate hypothesis, I suggest, is a proposition we hold to be true that fills in one or several of those relations. The problematic character of hypotheses requires that we evaluate our reasons for holding them to be true. While natural modality is grounded in the nature of things, which cannot be fully known, our reasons for assent can and must be grounded on features of objects that are epistemically available to us.

We investigate whether the disclosure of a firm’s decision to organize as a benefit corporation (BC) rather than a traditional C corporation (CC) influences investors. We survey 136 investors and 57 MBA students and find that they expect BCs to attain higher future corporate social responsibility (CSR) than CCs even when both have equal CSR ratings. Approximately one third of our sample prefers to invest in BCs when CCs have greater financial returns, indicating a willingness by some investors to sacrifice (...) personal financial gain for social good. Our results suggest that investors weight the information contained in BC disclosures as reliable and value-relevant in their investment decisions. We extend the CSR disclosure literature by indicating how investors weight this new type of CSR information, which may affect how BCs fare as publicly traded companies. (shrink)

The development of analogical reasoning has traditionally been understood in terms of theories of adult competence. This approach emphasizes structured representations and structure mapping. In contrast, we argue that by taking a developmental perspective, analogical reasoning can be viewed as the product of a substantially different cognitive ability – relational priming. To illustrate this, we present a computational (here connectionist) account where analogy arises gradually as a by-product of pattern completion in a recurrent network. Initial exposure to a situation primes (...) a relation that can then be applied to a novel situation to make an analogy. Relations are represented as transformations between states. The network exhibits behaviors consistent with a broad range of key phenomena from the developmental literature, lending support to the appropriateness of this approach (using low-level cognitive mechanisms) for investigating a domain that has normally been the preserve of high-level models. Furthermore, we present an additional simulation that integrates the relational priming mechanism with deliberative controlled use of inhibition to demonstrate how the framework can be extended to complex analogical reasoning, such as the data from explicit mapping studies in the literature on adults. This account highlights how taking a developmental perspective constrains the theory construction and cognitive modeling processes in a way that differs substantially from that based purely on adult studies, and illustrates how a putative complex cognitive skill can emerge out of a simple mechanism.

The purpose of this study was to evaluate, revise, and extend the Informed Consent Ontology (ICO) for expressing clinical permissions, including reuse of residual clinical biospecimens and health data. This study followed a formative evaluation design and used a bottom-up modeling approach. Data were collected from the literature on US federal regulations and a study of clinical consent forms. Eleven federal regulations and fifteen permission-sentences from clinical consent forms were iteratively modeled to identify entities and their relationships, followed by community (...) reflection and negotiation based on a series of predetermined evaluation questions. ICO included fifty-two classes and twelve object properties necessary when modeling, demonstrating appropriateness of extending ICO for the clinical domain. Twenty-six additional classes were imported into ICO from other ontologies, and twelve new classes were recommended for development. This work addresses a critical gap in formally representing permissions clinical permissions, including reuse of residual clinical biospecimens and health data. It makes missing content available to the OBO Foundry, enabling use alongside other widely-adopted biomedical ontologies. ICO serves as a machine-interpretable and interoperable tool for responsible reuse of residual clinical biospecimens and health data at scale. (shrink)

What would my life have been like if I had been born more intelligent? Or taller? Or a member of the opposite sex? Or a non-biological being? It is plausible that some of these questions make sense, while others stretch the limits of sense making. In addressing questions of how I might have been, genetic essentialism is popular, but this article argues that genetic essentialism, and other versions of origin essentialism for organisms, must be rejected. It considers the prospects for (...) counterpart theory and shows how counterpart theory can be used to illuminate volitional accounts of identity as proposed by Harry Frankfurt. This enables one to make sense of claims that, say, being gay, or Deaf, or Black, can be essential to someone's identity. The discussion is then extended to show how it can be made applicable to the transworld identity theorist who denies that individuals possess essential properties. (shrink)

Recent scholarship has steadily been opening up for philosophical study an increasingly wide range of the philosophical literature of antiquity. We no longer think only of Socrates, Plato and Aristotle, and their pre-Socratic forebears, when someone refers to the views of the ancient philosophers. Julia Annas has been one of the philosophers most closely engaged in the renewed study of Hellenistic philosophy over the past fifteen years, enabling herself and other scholars to acquire the necessary ground-level knowledge of the widely-dispersed (...) texts and the problems of interpretation—both historical and philosophical—that they present. In her new book she takes the next step. She presents to the general philosophical public of today an extended reconstruction of the systems of moral philosophy that were developed and pitted in competition with one another during the period when refinement and professionalism were at their height in Greek philosophy—between the end of the 4th and the middle of the 1st centuries B.C. These include the moral philosophies of Epicurus and his followers, several generations of Stoics, sceptical philosophers both Academic and Pyrrhonian, and the “hybrid” theories put together by Antiochus of Ascalon and other Stoic-influenced philosophers as part of the modernizing revival of Aristotelian ethical thought that took place in the 1st century B.C. She finds significant commonalities among these otherwise very disparate theories, and much of the book is devoted to examining these and showing how the conception of ethics and morality that is common to the ancient theorists compares with and differs from what we are familiar with in modern and contemporary theory. She traces these commonalities back to Aristotle in his ethical treatises, and accordingly includes Aristotle’s theory as one among those to be examined—indeed, in a significant sense as the intellectual father or grandfather of the rest of them. She leaves Plato’s dialogues out of account, and she has nothing to say about ethics and moral philosophy in the revived Platonism that gradually came to dominate philosophical thought in later antiquity. Her book, then, is a book about the structure and content of ancient ethical theory during the Hellenistic period, the period when Greek philosophy was at its high-point in professionalism and sophistication.

The author examines the question of Galen's affinity with astrology, in view of Galen's extended astrological discussion in the De diebus decretoriis . The critical passages from Galen are examined, and shown to be superficial in understanding. The author performs a lexical sounding of Galen's corpus, using key terms with astrological valences drawn from the Critical Days, and assesses their absence in Galen's other works. He compares Galen's astrology with the astrology of Ptolemy's Tetrabiblos, and evaluates their respective strategies (...) of scientific reasoning. Three types of inference are introduced and applied to Galen's astrology. Finally, he concludes that the empirical side of Galen's science does not depend upon astrological methods or concepts, but that these were introduced for their rhetorical effect in presenting his new medical methodology. It is suggested that continued attention to Galen's astrology has obscured the truly important empirical scientific method that Galen developed. (shrink)

The concept of population is central to ecology, yet it has received little attention from philosophers of ecology. Furthermore, the work that has been done often recycles ideas that have been developed for evolutionary biology. We argue that ecological populations and evolutionary populations, though intimately related, are distinct, and that the distinction matters to practicing ecologists. We offer a definition of ecological population in terms of demographic independence, where changes in abundance are a function of birth and death processes alone. (...) However, demographic independence is insufficient on its own so we supplement it with the idea of shared habitat. An ecological population is a group of organisms of the same species in a habitat that manifests DI. Given the importance of metapopulation dynamics to modern ecology, an account of ecological population must apply to this domain as well. Thus, we extend our definition of ecological population to the metapopulation. To facilitate the extension, we introduce the metahabitat—a collection of spatially segregated habitat patches shared by a single DI population. This enables us to diagnose some unhelpful trends in the metapopulation literature and emphasize the importance of habitat dynamics in pursuit of the goals of theoretical ecology and conservation biology.

In 1924, not quite two years after receiving his doctorate from the University of Vienna, Eric Voegelin was named a Laura Spelman Rockefeller Memorial Fellow and thus given the opportunity to pursue postdoctoral studies in the United States.

A more immediate result was the (...) publication in 1928 of _On the Form of the American Mind,_ the young philosopher's first major work, in which his acute perceptions and analyses combine with a conceptual vocabulary struggling to find its own coherence and form. Voegelin begins his inquiry into the form of the American mind with a complex discussion of the concepts of time and existence in European and American philosophy and continues with an extended interpretation of George Santayana, a study of the Puritan mystic Jonathan Edwards, a presentation on Anglo-American jurisprudence, and a consideration of the historian, economist, and political scientist John R. Commons. Although admitting that this diversity of themes seems only loosely connected," Voegelin demonstrates the actual overall unity of these various subjects: each concerns linguistic expressions of a theoretical nature. Analysis of _On the Form of the American Mind_ indicates that Voegelin integrated the approaches of _Lebensphilosophie_ into what Georg Misch called the "philosophical combination of anthropology and history," which characterized contemporary trends within the discourse of the _Geisteswissenschaften_ and finally resulted in a theoretical paradigm of philosophical anthropology.

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)

David KC Cooper,1 David Ayares21Thomas E Starzl Transplantation Institute, University of Pittsburgh Medical Center, Pittsburgh, PA, USA; 2Revivicor, Blacksburg, VA, USA: The transplantation of organs and cells from pigs into humans could overcome the critical and continuing problem of the lack of availability of deceased human organs and cells for clinical transplantation. Developments in the genetic engineering of pigs have enabled considerable progress to be made in the experimental laboratory in overcoming the immune barriers to successful xenotransplantation. With regard to (...) pig organ xenotransplantation, antibody- and cell-mediated rejection have largely been overcome, and the current major barrier is the development of coagulation dysregulation. This is believed to be due to a combination of immune activation of the vascular endothelial cells of the graft and molecular incompatibilities between the pig and primate coagulation–anticoagulation systems. Pigs with new genetic modifications specifically directed to this problem are now becoming available. With regard to less complex tissues, such as islets, neuronal cells, and corneas, the remaining barriers are less problematic, and graft survival in nonhuman primate models extends for >1 year in all three cases. In planning the initial clinical trials, consideration will be concentrated on the risk–benefit ratio, based to a large extent on the results of preclinical studies in nonhuman primates. If the benefit to the patient is anticipated to be high, eg, insulin-independent control of glycemia, and the potential risks low, eg, minimal risk of transfer of a porcine infectious agent, then a clinical trial would be justified.Keywords: infection, pigs, genetically-engineered, xenotransplantation, islets, xenotransplantation, organs.

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.

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.

This paper examines dispositional sources of workplace guanxi and the mediating role of workplace guanxi on the affectivity and job satisfaction relationship. Data were collected from 808 respondents in multiple industries in a city in China’s northeast. The study found that both positive affectivity and negative affectivity have an effect on supervisor–subordinate guanxi and co-worker guanxi, which supports the proposition that workplace guanxi has a dispositional source. Supervisor–subordinate guanxi has a positive relationship with job satisfaction, although co-worker guanxi is not (...) significantly related to job satisfaction. The research also found a mediating role of supervisor–subordinate guanxi on the affectivity and job satisfaction relationship, which suggests that supervisor–subordinate guanxi can extend the influence of affectivity to job satisfaction. Taken together, these results suggest that in a high power distance country such as China, supervisor–subordinate guanxi plays a more important role than co-worker guanxi in influencing job satisfaction. Theoretically, this study suggests the as yet unexplored possibility of dispositional antecedents of workplace guanxi and the role of workplace guanxi on the relationship between dispositions and workplace attitudes such as job satisfaction.

This article develops an institutional understanding of borders. Drawing on constitutive constructivism and theories of practical communication we argue that bordering as a process is a form of sorting through the imposition of status-functions on people and things, which alters the perception of that thing by setting it within a web of normative claims, teleologies and assumptions. Studying any border, therefore, extends to include the rule structure that constitutes it as well as the sources of that structure’s legitimacy. Furthermore, rule (...) structures are both restrictive and facilitative and importantly they overlap while retaining different sources of legitimacy: actors bring different constitutive perspectives on the border depending on the particular rule structure they are drawing on in order to make legitimate claims about what that border produces. This recognition sensitizes analysis to the interplay between different sense-making regimes and their authoritative underpinnings. Methodologically it points researchers towards the practical and discursive methods actors use when making arguments about what a particular border can and does do. (shrink)

Cross-sector social partnership case-based theory and research have long argued that nonprofits that engage in more integrative and enduring cross-sector partnerships should increase their organizational capacity. By increasing their capacity, nonprofits increase their ability to contribute to systemic change. The current research investigates this claim in a large-scale empirical research study. In particular, this study examines whether nonprofits that have a greater number of integrated cross-sector partnerships have greater capacities for financial management, strategic planning, external communication, board leadership, mission orientation, (...) and staff management than nonprofits that have other types of interorganizational relationships. Moreover, it examines whether the length of these partnerships is associated with better capacity. Hierarchical multiple regression analysis drawn from surveys of 452 nonprofit organizations suggests that cross-sector collaboration is not systematically related to increased capacity. However, the results suggest that more enduring relationships between government and nonprofit organizations that extend beyond funder–recipient relationships are related to greater strategic planning capacity. Implications for CSSP research are drawn from the results, especially those concerned with the outcomes of CSSPs. (shrink)

This paper examines the Fair Trade practices of Dure, a Korean consumer cooperative, through the extended cooperative enterprise citizenship framework. Extended cooperative citizenship means that cooperatives should replace citizenship and fill the gaps in the weakening public service sector. As dual-purpose business organizations, cooperatives have already played essential roles as extended corporate citizens. However, previous literature regarding CSR or cooperatives has not sufficiently explored the social responsibility of cooperatives. Furthermore, corporate citizenship is generally regarded as a singular (...) and static concept. Therefore, this paper analyses Dure’s Fair Trade practices through the newly developed framework. Significantly, this article clarifies how Dure collaborates with key stakeholders and upholds their civil, political, and social rights through Fair Trade. This paper also explains how cooperative enterprise citizenship has changed as Fair Trade practices have shifted. Two implications of this research are revealed. First, the paper develops a new analytical model to explain the dynamics of corporate citizenship and Fair Trade practices. Second, the research provides details about the social responsibility of Korean consumer cooperatives based on Fair Trade that will have practical applications for practitioners in the business sector.

Branching-time temporal logics have proved to be an extraordinarily successful tool in the formal specification and verification of distributed systems. Much of their success stems from the tractability of the model checking problem for the branching time logic CTL, which has made it possible to implement tools that allow designers to automatically verify that systems satisfy requirements expressed in CTL.

The resulting logic — Alternating-time Temporal Epistemic Logic (ATEL) — shares the tractability of model checking with its ATL parent, and is a succinct and expressive language for reasoning about game-like multiagent systems.

Coordinating behavior is widespread in contexts that include courtship, aggression, and cooperation for shared outcomes. The social significance of cooperative coordination (CC) is usually downplayed by learning theorists, evolutionary biologists, and game theorists in favor of an individual behavior → outcome perspective predicated on maximizing payoffs for all participants. To more closely model CC as it occurs under free-ranging conditions, pairs of rats were rewarded for coordinated shuttling within a shared chamber with unrestricted social interaction. Results show that animals (...) learned to work together with sensitivity to the task and type of partner. Moreover, social interaction and coordination influenced both consumption of the reward solution immediately following a session and preference for cooperation, suggesting that affective states and incentives related to cooperation extend beyond the outcomes obtained. These results support field studies by showing not only how cooperation is performed but also the importance of considering how the behavior of cooperating affects outcomes and preference for cooperating.

The surprise minimization principle has been applied to explain various cognitive processes in humans. Originally describing perceptual and active inference, the framework has been applied to different types of decision making including long-term policies, utility maximization and exploration. This analysis extends the application of surprise minimization to a multi-agent setup and shows how it can explain the emergence of social rules and cooperation. We further show that in social decision-making and political policy design, surprise minimization is superior in many (...) aspects to the classical approach of maximizing utility. Surprise minimization shows directly what value freedom of choice can have for social agents and why, depending on the context, they enter into cooperation, agree on social rules, or do nothing of the kind.

Queer objects are crucial to the narrative strategies of Dennis Cooper’s George Miles cycle where they support his exhaustive inventory of what it means to have a sexual type. In Frisk, Cooper transforms some objects into media to blur the boundaries between the writing subject and the objects he desires. The snuff photos, seen at too young an age, form the point of reference for Dennis the narrator’s erotic life but they acquire their force in a looping narrative structure that (...) calls into question their status as representation as well as their capacity to communicate. The novel thus elicits a new theorization of the relation between objects and media that discloses the stakes for fiction in a queer subjectivity that takes the self as another object at the same time as it probes the limits of realism. I situate Cooper in a genealogy of autofiction that extends back to Marcel Proust and Jean Genet and forward to J.T. LeRoy, Ben Lerner, Maggie Nelson, and Sheila Heti. The essay concludes by contrasting Cooper’s narrative achievements to the collapse of the writing subject into the autobiographical self in the more recent examples. (shrink)

This paper reports a longitudinal study on the ontogeny of triadic cooperative interactions in a hand-reared lowland gorilla from 6 months to 36 months of age. Using the behavioural categories developed by Hubley and Trevarthen to characterize the origins of “secondary intersubjectivity” in human babies between 8–12 months of age, I chart the emergence of comparable coordinations of gestures and actions with objects and acts of dyadic communication. The findings show that the categories and concepts of secondary intersubjectivity are applicable (...) to the gorilla, who engages with people in cooperative actions with objects. The ontogeny of triadic interaction in the gorilla was very similar to that described in human infants, but more extended in time and with some peculiarities, such as the absence of pointing and showing gestures, some of whose functions might be taken over by contact gestures which in human infants may appear later in development. The results do not support claims of human uniqueness in the development of cooperative action, but suggest a heterochrony in some aspects of the ontogeny of triadic interactions leading to a divergence between gorilla and human infants within secondary intersubjectivity. Keywords: Triadic communication; secondary intersubjectivity; shared intentionality; cooperation; gorilla. (shrink)

This paper reports a longitudinal study on the ontogeny of triadic cooperative interactions in a hand-reared lowland gorilla from 6 months to 36 months of age. Using the behavioural categories developed by Hubley and Trevarthen to characterize the origins of “secondary intersubjectivity” in human babies between 8-12 months of age, I chart the emergence of comparable coordinations of gestures and actions with objects and acts of dyadic communication. The findings show that the categories and concepts of secondary intersubjectivity are applicable (...) to the gorilla, who engages with people in cooperative actions with objects. The ontogeny of triadic interaction in the gorilla was very similar to that described in human infants, but more extended in time and with some peculiarities, such as the absence of pointing and showing gestures, some of whose functions might be taken over by contact gestures which in human infants may appear later in development. The results do not support claims of human uniqueness in the development of cooperative action, but suggest a heterochrony in some aspects of the ontogeny of triadic interactions leading to a divergence between gorilla and human infants within secondary intersubjectivity.

Groups of people perform acts that are subject to standards of rationality. A committee may sensibly award fellowships, or may irrationally award them in violation of its own policies. A theory of collective rationality defines collective acts that are evaluable for rationality and formulates principles for their evaluation. This book argues that a group's act is evaluable for rationality if it is the products of acts its members fully control. It also argues that such an act is collectively rational if (...) the acts of the group's members are rational. Efficiency is a goal of collective rationality, but not a requirement, except in cases where conditions are ideal for joint action and agents have rationally prepared for joint action.The people engaged in a game of strategy form a group, and the combination of their acts yields a collective act. If their collective act is rational, it constitutes a solution to their game. A theory of collective rationality yields principles concerning solutions to games. One principle requires that a solution constitute an equilibrium among the incentives of the agents in the game. In a cooperative game some agents are coalitions of individuals, and it may be impossible for all agents to pursue all incentives. Because rationality is attainable, the appropriate equilibrium standard for cooperative games requires that agents pursue only incentives that provide sufficient reasons to act. The book's theory of collective rationality supports an attainable equilibrium-standard for solutions to cooperative games and shows that its realization follows from individuals' rational acts.By extending the theory of rationality to groups, this book reveals the characteristics that make an act evaluable for rationality and the way rationality's evaluation of an act responds to the type of control its agent exercises over the act. The book's theory of collective rationality contributes to philosophical projects such as contractarian ethics and to practical projects such as the design of social institutions. (shrink)

The symposium included in this issue of Analyse & Kritik extends the basis of Cooperation Theory as set forth in Axelrod’s Evolution of Cooperation (1984). This essay begins with an overview of Cooperation Theory in terms of the questions it asks, its relationship to game theory and rationality, and the principal methodologies used, namely deduction and simulation. This essay then addresses the issues raised in the symposium, including the consequences of extending the original paradigm of the two (...) person iterated Prisoner’s Dilemma to take into account such factors as nonsimultaneous play, the ability to offer hostages for performance, social networks of interaction, information sharing that can support reputations, learning behavior, envy, misunderstanding, and an option to exit. The essay places the contributions of this symposium in the context of previous research on these and related issues. (shrink)

I want to extend here a line of reasoning that I pursued in Rationality and Dynamic Choice . In that book I argued that the standard Bayesian model of expected-utility reasoning needs to be revised to accommodate a capacity, on the part of rational decision-makers, to effectively coordinate with their own future selves — to be guided by plans that they have deliberately adopted. I also suggested that an analogous line of reasoning might be employed to show that rational agents (...) could engage in rule-governed coordination of their choices with one another to a greater extent than the standard theory would seem to admit. It is this suggestion that I now want to explore more fully in the present paper. It is not that the standard theory denies the possibility of such coordination. On that account, however, coordination can only be achieved by the adoption of an effective enforcement system. Since, however, any enforcement scheme requires the expenditure of scarce resources, the standard theory seems committed to the view that rational agents can achieve only a second best outcome. It is worth considering whether thoroughly rational persons who know each other to be such might not do better than this. It is also the case that the process whereby individuals come to agreement on the terms of their coordination schemes is conceived as driven essentially by non-cooperative considerations, specifically the relative bargaining power or threat advantage of the participants. Bargaining outcomes based on this principle, however, tend to generate mutually disadvantageous conflict, and thus there are greater costs yet to be borne by “rational” interacting agents. I shall have to leave the exploration of this second problem to another occasion, however. (shrink)

"No human now gathers for himself or herself the essential resources for life: food, shelter, clothing, and the like. Humans are obligate co-operator, and this has been true for tens of thousands of years; probably much longer. In this regard, humans are very unusual. Cooperation outside the family is rare: though it can be very profitable, it is also very risky, as cooperation makes an agent vulnerable to incompetence and cheating. This book presents a new picture of the (...) emergence of cooperation in our lineage, developing through four fairly distinct phases from a baseline that was probably fairly similar to living great apes, who cooperate, but in fairly minimal ways. As adults, they rarely depend on others when the outcome really matters. This book suggests that cooperation began to be more important for humans through an initial phase of cooperative foraging generating immediate returns from collective action in small mobile bands. This established in our lineage about 1.8 million years ago, perhaps earlier. Over the rest of the Pleistocene, cooperation became more extended in its social scale, with forms of cooperation between bands gradually establishing, and in spatial and temporal scale too, with various forms of reciprocation becoming important. The final phase was the emergence of cooperation in large scale, hierarchical societies in the Holocene, beginning about 12,000 years ago. This picture is nested in a reading of the archaeological and ethnographic record, and twinned to an account of the gradual elaboration of cultural learning in our lineage, making cooperation both more profitable and more stable"--.

InMorals by Agreement, David Gauthier (1986) argues that it is rational to intend to cooperate, even in single-play Prisoner's Dilemma games, provided (1) your co-player has a similar intention; (2) both intentions can be revealed to the other player. To this thesis four objections are made. (a) In a strategic decision the parameters on which the argument relies cannot be supposed to be given. (b) Of each pair ofa-symmetric intentions at least one is not rational. But it is impossible to (...) form symmetric intentions to cooperate conditionally. For the condition on which the decision depends cannot be fulfilled without deciding. (c) If one's intention has to be ascertained on the basis of information about one's past performance, it is straightforwardly rational to intend to cooperate, but there is no reason to do so in a single-play PD. (d) The argument cannot be extended ton-person games which are Gauthier's principal concern. (shrink)

The disaggregation and geographic dispersion of global value chains (GVCs) have expanded the responsibility of international buyers from firm-level corporate social responsibility (CSR) towards social sustainability of their emerging country suppliers. We theorize, in this paper, that the effectiveness of lead firms’ GVC governance strategies for social sustainability—which can be audit-based or cooperation-based—depends on the local institutional context of the supplier. Supplier country institutions exert legal and civil society pressures for social sustainability, which shape suppliers’ attitude and receptiveness towards (...) lead firm requests. Using unique primary data from 356 garment and footwear suppliers in 11 emerging countries, which supply to Western European or North American buyers, we show that GVC governance strategies are particularly effective for suppliers’ social sustainability implementation when there is ‘contextual fit’ with local institutional pressures for social sustainability in the supplier country. Our study identifies the boundary conditions of GVC governance modes, and demonstrates a complementary relationship between organizational arrangements and their institutional-level counterparts in the context of social sustainability.

In a series of papers, Forber and Smead :151–166, 2014, Biol Philos 30:405–421, 2015) and Smead and Forber :698–707, 2013) make a valuable contribution to the study of cooperation in finite populations by analyzing an understudied model: the prisoner’s delight. It always pays to cooperate in the one-shot prisoner’s delight, so this model presents a best-case scenario for the evolution of cooperation. Yet, what Forber and Smead find is highly counterintuitive. In finite populations playing the prisoner’s delight, increasing (...) the benefit of cooperation causes selection to favor defection. Here, I extend their model by considering the effects of non-linear payoffs. In particular, I show that interesting subtleties arise when payoffs are synergistic. Indeed, analysis reveals that increasing the benefit of cooperation does not always favor the spread of defection if payoffs are synergistic. I conclude by drawing some general considerations about robustness analysis in evolutionary models. (shrink)

In this paper, we introduce an ecological account of communication according to which acts of communication are active inferences achieved by affecting the behavior of a target organism via the modification of its field of affordances. Constraining a target organism’s behavior constitutes a mechanism of socially extended active inference, allowing organisms to proactively regulate their inner states through the behavior of other organisms. In this general conception of communication, the type of cooperative communication characteristic of human communicative interaction is (...) a way of constraining interaction dynamics toward the goals of a given joint action by constructing and altering shared fields of affordances. This account embraces a pragmatist view according to which communication is a form of action aiming to influence the behavior of a target, and stands against the traditional transmission view according to which communication fundamentally serves to convey information. Understanding acts of communication as active inference under an ecological interpretation allows us to link communicative and ultimately linguistic behavior to the biological imperative of minimizing free energy and to emphasize the action-oriented nature of communicative interaction.

The notion that emotional expressions regulate social life by providing information is gaining popularity. Prior research on the effects of emotional expressions on observers’ inferential processes has focused mostly on inferences regarding the personality traits of the expresser, such as dominance and affiliation. We extend this line of research by exploring the possibility that emotional expressions shape observers’ construal of social situations. Across three vignette studies, an interaction partner's expressions of anger, compared to expressions of happiness or disappointment, led observers (...) to construe hypothetical situations as less cooperative, both in dyads and groups. These effects occurred even when factual information regarding the cooperativeness or competitiveness of the situation was provided, attesting to the power of emotional expressions in shaping the construal of social situations. Results are discussed in relation to appraisal theory, reverse appraisals, emotions as social information theory, and the emergence of cooperation in groups and cultures. (shrink)

Understanding cooperative human behaviour depends on insights into the biological basis of human altruism, as well as into socio-cultural development. In terms of evolutionary theory, kinship and reciprocity are well established as underlying cooperativeness. Reasons will be given suggesting an additional source, the capability of a cognition-based empathy that may have evolved as a by-product of strategic thought. An assessment of the range, the intrinsic limitations, and the conditions for activation of human cooperativeness would profit from a systems approach combining (...) biological and socio-cultural aspects. However, this is not yet the prevailing attitude among contemporary social and biological scientists who often hold prejudiced views of each other's notions. It is therefore worth noticing that the desirable integration of aspects has already been attempted, in remarkable and encouraging ways, in the history of thought on human nature. I will exemplify this with the ideas of the fourteenth century Arab-Muslim historian Ibn Khaldun. He set out to explicate human cooperativeness - "asabiyah" - as having a biological basis in common descent, but being extendable far beyond within social systems, though in a relatively unstable and attenuated fashion. He combined psychological and material factors in a dynamical theory of the rise and decline of political rulership, and related general social phenomena to basic features of human behaviour influenced by kinship, expectation of reciprocity, and empathic emotions. -/- .

Cosmopolitans argue that the account of human rights and distributive justice in John Rawls's The Law of Peoples is incompatible with his argument for liberal justice. Rawls should extend his account of liberal basic liberties and the guarantees of distributive justice to apply to the world at large. This essay defends Rawls's grounding of political justice in social cooperation. The Law of Peoples is drawn up to provide principles of foreign policy for liberal peoples. Human rights are among the (...) necessary conditions for social cooperation, and so long as a decent people respect human rights, a common good, and the Law of Peoples, it is not the role of liberal peoples to impose upon well-ordered decent peoples liberal liberties they cannot endorse. Moreover, the difference principle is not an allocative or alleviatory principle, but applies to design property and other basic social institutions necessary to economic production, exchange and consumption. It presupposes political cooperation—a legislative body to actively apply it, and a legal system to apply it to. There is no feasible global state or global legal system that could serve these roles. Finally, the difference principle embodies a conception of democratic reciprocity that is only appropriate to cooperation among free and equal citizens who are socially productive and politically autonomous. a Footnotesa I am grateful to K.
