Brian Skyrms has argued that the evolution of the social contract may be explained using the tools of evolutionary game theory. I show in the first half of this paper that the evolutionary game-theoretic models are often highly sensitive to the specific processes that they are intended to simulate. This sensitivity represents an important robustness failure that complicates Skyrms's project. But I go on to make the positive proposal that we may none the less obtain robust results by simulating the (...) population structures that existed among our evolutionary ancestors. It is by extending the evolutionary models in this way that we should pursue the project of explaining the evolution of the social contract. (shrink)

Shortest possible axiomatizations for the implicational fragments of the modal logics S4 and S5 are reported. Among these axiomatizations is included a shortest single axiom for implicational S4—which to our knowledge is the first reported single axiom for that system—and several new shortest single axioms for implicational S5. A variety of automated reasoning strategies were essential to our discoveries.

A variety of robustness objections have been made against evolutionary game theory. One of these objections alleges that the games used in the underlying model are too arbitrary and oversimplified to generate a robust model of interesting prosocial behaviors. In this paper, I argue that the robustness objection can be met. However, in order to do so, we must attend to important conceptual issues regarding the nature of fairness, justice, and other moral concepts. Specifically, we must better understand the relationship (...) between moral concepts and formal characterizations of games. (shrink)

Human beings are highly irrational, at least if we hold to an economic standard of ‘rationality’. Experimental economics studies the irrational behavior of human beings, with the aim of understanding exactly how our behavior deviates from the Homo economicus, as ‘rational man’ has been called. Insofar as philosophical theories depend upon rationality assumptions, experimental economics is the source of both problems and (at least potential) solutions to several philosophical issues. This article offers a programmatic and highly biased survey of some (...) of these issues, with the hope of convincing the reader that experimental economics is well-deserving of careful study by philosophers.

Common knowledge is usually defined as a state in which everyone knows that p, everyone knows that everyone knows that p, and so on, ad infinitum. This definition is usually attributed to David Lewis, despite the fact that his own formulation bears no resemblance to common knowledge as it is usually understood. In this paper, I argue that this concept of common knowledge requires revision. Contrary to usual practice, it turns out to be difficult to model formally because existing models (...) fail to distinguish between full-blown common knowledge and merely finite levels of interactive knowledge. Conceptually, the concept is incompatible with Lewis's intended purpose and obscures the explanatory role played by rational choice models. I propose that the concept of common knowledge be brought better into alignment with Lewis's actual formulation. This reconceptualization of common knowledge suggests a greater focus on explanations that make recourse to the cognitive constraints of real-world agents. (shrink)

Recently advocates of the propensity interpretation of fitness have turned critics. To accommodate examples from the population genetics literature they conclude that fitness is better defined broadly as a family of propensities rather than the propensity to contribute descendants to some future generation. We argue that the propensity theorists have misunderstood the deeper ramifications of the examples they cite. These examples demonstrate why there are factors outside of propensities that determine fitness. We go on to argue for the more general (...) thesis that no account of fitness can satisfy the desiderata that have motivated the propensity account. (shrink)

We argue that conceptual analyses of collective action should be informed by game-theoretic analyses of collective action. In particular, we argue that Ariel Rubenstein’s so-called ‘Electronic Mail Game’ provides a useful model of collective action, and of the formation of collective intentions.

In numerous studies, experimental economists have documented the fact that people tend to propose that divisible goods be divided equally. It has often been proposed, most notably by the sociobiologists, that this tendency may have a biological basis, and might be the product of evolution and natural selection. ;My dissertation addresses methodological and philosophical problems that arise in the course of establishing this naturalistic claim. Specifically, the focus of this dissertation is on the project of using evolutionary game theory to (...) model the emergence of behavioral norms in a population. ;Chapter 1 briefly surveys the experimental economics literature that supports the existence of such behavioral propensities, and gives an overview of the dissertation. Chapter 2 introduces the fundamental concepts of game theory and evolutionary game theory. Chapter 3 argues that certain robustness failures may be overcome if group selection mechanisms are incorporated into the evolutionary models. Chapter 5 defends Peter Railton's causal theory of explanation, and argues that it best accommodates the dynamical models of evolutionary game theory. Chapter 6 addresses the question of whether a descriptive account of the origins of our moral intuitions is relevant to the normative project of identifying our moral obligations, and critiques arguments by Peter Singer and Peter Unger that our moral intuitions lack justification.

Writers on collective action are in broad agreement that in order for a group of agents to form a collective intention, the members of that group must have beliefs about the beliefs of the other members. But in spite of the fact that this so-called "interactive knowledge" is central to virtually every account of collective intention, writers on this subject have not offered a detailed account of the nature of interactive knowledge. In this paper, we argue that such an account (...) is necessary for any adequate analysis of collective intention. Furthermore, we argue that an application of Robert Aumann's theory of interactive knowledge may be used to address several puzzling features of collective intention.

In this paper, we offer an analysis of ‘group intentions.’ On our proposal, group intentions should be understood as a state of equilibrium among the beliefs of the members of a group. Although the discussion in this paper is non-technical, the equilibrium concept is drawn from the formal theory of interactive epistemology due to Robert Aumann. The goal of this paper is to provide an analysis of group intentions that is informed by important work in economics and formal epistemology.

This essay examines the physicist Ernst Mach’s popular work. Like many other scientists in late nineteenth-century Central Europe, he viewed the popular genre as a means not only of edifying the lay public but of communicating arguments to other specialists. In many cases, he used his popularizations to draw his colleagues’ attention to the biological and evolutionary features of scientific reasoning, although his own understanding of those features changed in the 1880s and early 1890s. Notably, he came to believe (...) that human beings instinctively read substances into nature. Several years after adopting this new perspective on substance, he incorporated it into a series of popular works that were intended to outline his views on thermodynamics in general and to weigh in on the controversy over “energetics” that erupted at the 1895 Versammlung Deutscher Naturforscher und Ärtze.

In the heart of southeast Texas, an industrial powerhouse often referred to as the 'Golden Triangle', the oil refineries and petrochemical plants stand as stalwart testaments to the region's economic evolution. Interestingly, before the discovery of oil at Spindletop, the lumber and cattle industries powered this region's economy. A profound shift occurred when the Lucas Gusher, a fountain of oil spurting thousands of feet into the air, struck the lands of Spindletop Hill on January 10, 1901. This remarkable discovery of (...) the Spindletop oilfield on a slat dome formation south of Beaumont, Texas, marked the birth of the modern petroleum industry and fundamentally transformed the region's geopolitical, economic, and cultural landscapes. People from all over the country relocated to Gladys City and Beaumont in search of work and new opportunities, creating a boomtown as the town's population swelled from 10,000 to 50,000. The newfound urbanization brought by the oil industry transformed the town and the surrounding areas, creating a ripple effect across the region that would be felt for generations to come. The surge in oil-driven economic activity transmuted the region into a vibrant nexus of commerce, with the oil industry emerging as a critical architect of growth and advancement. This newfound affluence incited by the petroleum sector ushered in an era of economic diversification, laying the groundwork for industrialization’s further evolution. The Spindletop Oil Fields not only underscored the United States’ ascent as the foremost petroleum-producing nation but also signaled the nation’s initiation into the Petroleum Age. It was Spindletop that solidified its position as America’s first significant oil field, becoming an enduring symbol of its industrial might. By 1985, over 153,000,000 barrels of oil had been produced and extracted from the Spindletop oil fields, underscoring the magnitude of this extraordinary resource. (shrink)

Causal models of agents have been used to analyse the safety aspects of machine learning systems. But identifying agents is non-trivial -- often the causal model is just assumed by the modeler without much justification -- and modelling failures can lead to mistakes in the safety analysis. This paper proposes the first formal causal definition of agents -- roughly that agents are systems that would adapt their policy if their actions influenced the world in a different way. From this we (...) derive the first causal discovery algorithm for discovering agents from empirical data, and give algorithms for translating between causal models and game-theoretic influence diagrams. We demonstrate our approach by resolving some previous confusions caused by incorrect causal modelling of agents. (shrink)

Descartes maintains that we can love God and that it is pleasant and morally beneficial to do so. In this essay, I examine the necessary conditions for such an intellectual love of God. I argue that the intellectual love of God is incited by a judgment that we are joined to God in reality, which is constitutive of an intellectual joy. I go on to show that the intellectual love of God is, itself, constituted by a stripping of our private (...) interests in favor of God’s divine will. (shrink)

The aim of this book is to reflect on the complex practice of responsibility within the context of a globalised world and contemporary means of action. Levinas' exploration of the ethical serves as point of entry and is shown to be seeking inter-cultural political relevance through engagement with the issues of postcoloniality and humanism. Yet, Levinas fails to realise the ethical implications of the inevitable instrumental mediation between ethical meaning and political practice. With recourse to Weber, Apel and Ricoeur, (...) class='Hi'>Ernst Wolff proposes a theory of strategic co-responsibility for the uncertain global context of practice. (shrink)

Research on economization processes is increasingly taking seriously the social and material processes through which various policy domains are transformed into economic problems and solutions. This article engages “Value Added Modeling” (VAM) in teacher evaluation systems as a case study in economization. VAM is a statistical technology for evaluating the effectiveness of schoolteachers using student test scores, which wrests authority for the determination of quality teaching away from education professionals and toward quantitative economic modelers. Mobilizing field theory, we trace a (...) half century of changing relationships among economists, other academics, and various policy audiences (from media to philanthropists to state and federal government) in struggles to define education policy concerning teacher quality. We show that economization is a set of overlapping, sometimes contradictory processes that can take different forms: in this case, the spread of an “economic style of reasoning” or the establishment of “economic policy devices.” The case of VAM shows stages of economization in which processes first proceeded independently of one another, then interacted in contradictory ways, and finally, mutually reinforced one another. What primarily drove these interactions was the struggle for scientific capital within the economics discipline and the changing place of education policy and VAM within it. Ultimately, VAM’s original role as a policy device for evaluating and selecting individual teachers has foundered even as it has become an important tool for economists to accrue scientific capital and expand their style of reasoning to broader audiences.

Doxastic normativism is the thesis that norms are constitutive of or essential to belief, such that no mental state not subject to those norms counts as a belief. A common normativist view is that belief is essentially governed by a norm of truth. According to Krister Bykvist and Anandi Hattiangadi, truth norms for belief cannot be formulated without unpalatable consequences: they are either false or they impose unsatisfiable requirements on believers. I propose that we construe the fundamental norm of belief (...) as a knowledge norm, rather than a truth norm. I argue that a specific kind of knowledge norm—one that has a subject's obligation to believe that p depend on her being in a position to know that p—might avoid the well-known formulation problems with truth norms.

Arguments from Silence have been used many times in attempts to discredit the foundations of religions. In this project, I demonstrate how one might judge the epistemic value of such arguments. To begin, I lay out for examination a specific argument from silence given by Walter Richard Cassels in his work Supernatural Religion. I then discuss a recently developed Bayesian approach for dealing with arguments from silence. Finally, using Cassels’s work and the work of some of the critics who replied (...) to his argument, I argue for what probabilities might be applied in the use of the Bayesian method for testing the epistemic value Cassels’s argument and demonstrate how one might respond to similar arguments.

Normativists about belief hold that belief formation is essentially rule- or norm-guided. On this view, certain norms are constitutive of or essential to belief in such a way that no mental state not guided by those norms counts as a belief, properly construed. In recent influential work, Kathrin Glüer and Åsa Wikforss develop novel arguments against normativism. According to their regress of motivations argument, not all belief formation can be rule- or norm-guided, on pain of a vicious infinite regress. I (...) argue that the regress of motivations argument is unsuccessful: an appeal to the notion of blind rule-following, drawn from a plausible interpretation of Ludwig Wittgenstein’s remarks on rule-following, stops the regress of motivations in its tracks.

Paul Griffiths and John Matthewson argue that selected effects play the key role in determining whether a state is pathological. In response, it is argued that a selected effects account faces a number of difficulties in light of modern genomic research. Firstly, a modern history approach to selection is problematic as a basis for assigning function to human traits in light of the small population sizes in the hominin lineage, which imply that selection has played a limited role in shaping (...) these genomes in the evolutionarily recent past. Secondly, determining both the genetic basis of disease and selective histories of the various alleles involved may be experimentally intractable. Thirdly, the existence of “selected disorders” is well supported, and yet on the other hand many other common diseases may not reduce evolutionary fitness. In summary, the biological ends promoted by natural selection, as best modeled in recent research, do not adequately ground a concept of dysfunction that aligns well with the interests of human health.

Much has been written about the ethics of eating meat. Far less has been said about the ethics of serving meat. In this paper I argue that we often shouldn’t serve meat, even if it is morally permissible for individuals to purchase and eat meat. Historically, the ethical conversation surrounding meat has been limited to individual diets, meat producers, and government actors. I argue that if we stop the conversation there, then the urgent moral problems associated with industrial animal agriculture (...) will go unsolved. Instead, we must also consider the important but overlooked role that midsized institutions play in addressing major collective problems. I focus mostly on the harms that industrial animal agriculture inflicts on humans, animals, and the environment, but the discussion bears on other global issues like climate change. Institutional choices are an underexplored avenue for driving social change—their power and influence outstrip individual actions, and they can shape behavior in modest ways that promote social goods. Here I highlight the paradigmatic case of catered events and suggest three ways that institutional actors can reduce meat consumption and shape cultural attitudes surrounding meat: large impact decisions, subtly shaping incentives, and consolidating burdens.

The propensity interpretation of fitness (PIF) holds that evolutionary fitness is an objectively probabilistic causal disposition (i.e., a propensity) toward reproductive success. I characterize this as the conceptual foundation of the PIF. Reproductive propensities are meant to explain trends in actual reproductive outcomes. In this paper, I analyze the minimal theoretical and ontological commitments that must accompany the explanatory power afforded by the PIF’s foundation. I discuss three senses in which these commitments are less burdensome than has typically been recognized: (...) the PIF’s foundation is (i) compatible with a principled pluralism regarding the mathematical relationship between measures of individual and trait reproductive success; (ii) independent of the propensity interpretation of probability; and (iii) independent of microphysical indeterminism. The most substantive ontological commitment of the PIF’s foundation is to objective modal structures wherein macrophysical probabilities and causation can be found, but I hedge against metaphysically inflationary readings of this modality.

A semantic theory aims to make predictions that are accurate and comprehensive. Sometimes, though, a semantic theory falls short of this aim, and there is a mismatch between prediction and data. In such cases, defenders of the semantic theory often attempt to rescue it by appealing to Gricean pragmatics. The hope is that we can rescue the theory as long as we can use pragmatics to explain away its predictive failures. This pragmatic rescue strategy is one of the most popular (...) moves in philosophy of language, philosophical logic, and formal semantics. In this paper I argue that this strategy fails whenever the predictive failures at issue can be recast in epistemological or metaphysical terms. This general “reformulation argument” undermines a wide variety of pragmatic rescue attempts. (shrink)

Individualist normative theories appear inadequate for the complex moral challenges of climate change. In climate ethics, this is especially notable with the relative marginalization of Kant. I argue that Kant’s philosophy, understood through its historical and cosmopolitan dimensions, has untapped potential for the climate crisis. First, I situate Kant in climate ethics and evaluate his marginalization due to perceived individualism, interiority and anthropocentrism. Then, I explore aspects of Kant’s historical and cosmopolitan writings, which present a global, future-orientated picture of humanity. (...) Ultimately, Kant’s philosophy offers a unique take on the climate deadlock capable of sustaining the individual in the collective. (shrink)

For decades, scholars in the social sciences and humanities have questioned the appropriateness and utility of prior review of their research by human subjects' ethics committees. This essay seeks to organize thematically some of their published complaints and to serve as a brief restatement of the major critiques of ethics review.

By recovering the dependent, often enslaved, laborers who helped to make European medicines commercially available in the New England colonies, this article offers a new history of early American pharmaceutical knowledge and production. It does so by considering the life and labor of an unnamed, enslaved assistant who was said to make tinctures, elixirs, and other common remedies in a 1758 letter between two business partners, Silvester Gardiner, a successful surgeon and apothecary in Boston, Massachusetts, and William Jepson, his former (...) apprentice, in Hartford, Connecticut. Using strategies from slavery and critical archive studies, as well as from social history and the history of medicine, this article emphasizes the materiality and embodiment of pharmaceutical production and follows fragmentary evidence beyond the business archive to reverse the systemic erasure of enslaved and indentured laborers from the records of eighteenth-century manufacturers of medicines. The medicine trades of men like Gardiner and Jepson appear more reliant upon dependent laborers – named and unnamed – who not only performed rote tasks but brought their experience and judgment to their labors as well. Their contributions could be obviously medical (preparing remedies) or more ambiguous (stoking fires, shipping goods), but these actions together constituted early modern pharmacy, enabled the expansion of the transatlantic medicine trade, and laid the foundations for the more self-sufficient and industrialized pharmacy that developed in the nineteenth century. Centering the skill and knowledge among subordinated laborers in one facet of an emergent transatlantic care economy affirms the entanglement of slavery and science and underscores the necessity of asking new questions of old sources.

A number of thinkers have been wondering about the moral obligations humans have, or will have, to intelligent technologies. An underlying assumption is that “moral machines” are decades in the offing, and thus we have no pressing obligations now. But, in the context of technology, we are yet to consider that we might owe moral consideration to something that is not a member of the moral community but eventually will be as an outcome of human action. Do we have current (...) actual obligations to technologies that do not currently exist? If there are obligations to currently non-existing technologies, we must confront what might be called the Non-Identical Machines Problem. Can we harm or benefit an entity by making it one way rather than another? This paper presents the problem and argues that it is more challenging than the standard Non-Identity Problem. (shrink)

Recently, Christine Bratu and Mortiz Dittmeyer have argued that Christine Korsgaard’s constitutive project fails to establish the normativity of practical principles because it fails to show why a principle’s being constitutive of a practice shows that one ought to conform to that principle. They argue that in many cases a principle’s being constitutive of a practice has no bearing on whether one ought to conform to it. In this paper I argue that Bratu and Dittmeyer’s argument fails in three important (...) respects. First, they fail to recognize the ways in which Korsgaard’s neo-Kantian view departs from more orthodox Kantian views. Second, they fail to recognize the respect in which Korsgaard’s view is a version of moral rationalism. Third, they overlook an important scope ambiguity in an important premise of their argument. A sensible way of resolving this ambiguity gives the constitutivist a reasonable response. (shrink)

In this paper I argue that Kant’s pre-critical ontology, though generally dismissed by environmental philosophers, provides ecological lessons by way of its metaphysical affinities with environmental philosophy. First, I reference where environmental philosophy tends to place Kant and highlight his relative marginalization. This marginalization makes sense given focus on his critical works. I then outline Kant’s pre-critical ontological framework and characterize the ways in which it is ecological. Finally, I conclude with some ecological reflections on the pre-critical philosophy and its (...) possible relevance for contemporary environmental issues. (shrink)

The principle of Anteriority says that prospects that are identical from the perspective of every possible person’s welfare are equally good overall. The principle enjoys prima facie plausibility, and has been employed for various theoretical purposes. Here it is shown using an analogue of the St Petersburg Paradox that Anteriority is inconsistent with central principles of axiology.

The famous EPR article of 1935 challenged the completeness of quantum mechanics and spurred decades of theoretical and experimental research into the foundations of quantum theory. A crowning achievement of this research is the demonstration that nature cannot in general consist in noncontextual pre-measurement properties that uniquely determine possible measurement outcomes, through experimental violations of Bell inequalities and Kochen-Specker theorems. In this article, I reconstruct an argument from Niels Bohr’s writings that the reality of the Einstein-Planck-de Broglie relations alone implies (...) that no such properties can exist for momentum and position measurements, show how this argument responds to the challenge of EPR on general physical grounds, and advance that this reconstruction shows that and how Bohr’s “complementarity” is a view of the objective content and logic of quantum theory.

This paper re-examines the dispute concerning Hobbes’s religious beliefs in light of his natural philosophy. First, I argue that atheistic readings of Hobbes can be more plausibly defended provided interpreters make use of a methodological unity thesis. Second, I suggest that theistic readers of Hobbes have good reason to favor the autonomy thesis. I conclude by highlighting how a re-examination of the theism dispute motivates reconsideration of the role of Hobbes’s natural philosophy and scientific methodology vis à vis politics. Maintaining (...) the unity thesis as a methodological device can shed important light on the politics and methods of Leviathan. More importantly, this analysis motivates consideration of De Corpore in any serious study of Hobbes. (shrink)

Assyriologists who have studied Mesopotamian commentary formation have drawn upon ideas from scholars of religion in treating the creation of a static canon at the end of the second millennium bce as a necessary precondition for the emergence of cuneiform commentaries. The present contribution argues against the idea that Mesopotamian commentaries emerged in response to a closed canon by marshaling evidence from Mesopotamian divinatory compositions, including the celestial-divinatory series Enūma Anu Enlil and its associated aḫû, or “extraneous” tradition, as well (...) as the extispical treatise Bārûtu. These compositions illustrate that commentaries could be written about texts that were still fluid and malleable in ancient Mesopotamia. Moreover, a brief look at the phenomenon of inner biblical exegesis in the Hebrew Bible supports the idea that texts need not be unchanging to be the subject of interpretation, whether in ancient Mesopotamia or elsewhere. In response to these conclusions, I outline an alternate theory for Mesopotamian commentary formation that eschews the importance of a closed canon and stresses instead ideas of scholarly bilingualism, divination, authority, and textual decorum in ancient Iraq.

Although scientists dating back to Darwin have noted the importance of the body in communicating emotion, current research on emotion communication tends to emphasize the face.

Although no extant coding system provides an exhaustive list of bodily behaviors known to (...) communicate a panoply of emotions, our review provides the foundation for developing such a system.

This study tested four theoretical models of leadership with data from the ethnographic record. The first was a game-theoretical model of leadership in collective actions, in which followers prefer and reward a leader who monitors and sanctions free-riders as group size increases. The second was the dominance model, in which dominant leaders threaten followers with physical or social harm. The third, the prestige model, suggests leaders with valued skills and expertise are chosen by followers who strive to emulate them. The (...) fourth proposes that in small-scale, kin-based societies, men with high neural capital are best able to achieve and maintain positions of social influence (e.g., as headmen) and thereby often become polygynous and have more offspring than other men, which positively selects for greater neural capital. Using multiple search strategies we identified more than 1000 texts relevant to leadership in the Probability Sample of 60 cultures from the Human Relations Area Files (HRAF). We operationalized the model with variables and then coded all retrieved text records on the presence or absence of evidence for each of these 24 variables. We found mixed support for the collective action model, broad support for components of the prestige leadership style and the importance of neural capital and polygyny among leaders, but more limited support for the dominance leadership style. We found little evidence, however, of emulation of, or prestige-biased learning toward, leaders. We found that improving collective actions, having expertise, providing counsel, and being respected, having high neural capital, and being polygynous are common properties of leaders, which warrants a synthesis of the collective action, prestige, and neural capital and reproductive skew models. We sketch one such synthesis involving high-quality decision-making and other computational services. (shrink)

Markosian presents an argument against certain theories of time based on the aesthetic value of music. He argues that turning a piece of music sideways in time destroys its intrinsic value, which would not be possible if the Spacetime Thesis were true. In this paper I show that sideways music poses no problems for any theory of time by demonstrating that turning a piece of music sideways does not affect its intrinsic value. I do this by appealing to spatial analogies (...) that highlight the similarities between spatial and temporal rotations. (shrink)
