Contemporary societies are often “polarized”, in the sense that sub-groups within these societies hold stably opposing beliefs, even when there is a fact of the matter. Extant models of polarization do not capture the idea that some beliefs are true and others false. Here we present a model, based on the network epistemology framework of Bala and Goyal, 784–811 1998), in which polarization emerges even though agents gather evidence about their beliefs, and true belief yields a pay-off advantage. As we (...) discuss, these results are especially relevant to polarization in scientific communities, for these reasons. The key mechanism that generates polarization involves treating evidence generated by other agents as uncertain when their beliefs are relatively different from one’s own. (shrink)

An expansive, yet succinct, analysis of the Philosophy of Religion – from metaphysics through theology. Organized into two sections, the text first examines truths concerning what is possible and what is necessary. These chapters lay the foundation for the book’s second part – the search for a metaphysical framework that permits the possibility of an ultimate explanation that is correct and complete. A cutting-edge scholarly work which engages with the traditional metaphysician’s quest for a true ultimate explanation of the most (...) general features of the world we inhabit Develops an original view concerning the epistemology and metaphysics of modality, or truths concerning what is possible or necessary Applies this framework to a re-examination of the cosmological argument for theism Defends a novel version of the Leibnizian cosmological argument.

Intersectionality theory explores the special sorts of disadvantage that arise as the result of occupying multiple disadvantaged demographic categories. One significant methodological problem for the quantitative study of intersectionality is the difficulty of acquiring data sets large enough to produce significant results when one is looking for intersectional effects. For this reason, we argue, simulation methods may be particularly useful to this branch of theorizing because they can generate precise predictions and causal dependencies in a relatively cheap way, and can (...) thus guide future empirical work. We illustrate this point through models which show that intersectional oppression can arise under conditions where social groups are disadvantaged in the emergence of bargaining norms. As we show, intersectional disadvantage can arise even when actors from all social categories are completely identical in terms of preferences and abilities. The conditions necessary to derive such disadvantage are relatively minimal. And when actors behave in ways that reflect stronger intersectional identities, the potential for disadvantage increases.

Vague predicates, those that exhibit borderline cases, pose a persistent problem for philosophers and logicians. Although they are ubiquitous in natural language, when used in a logical context, vague predicates lead to contradiction. This paper will address a question that is intimately related to this problem. Given their inherent imprecision, why do vague predicates arise in the first place? I discuss a variation of the signaling game where the state space is treated as contiguous, i.e., endowed with a metric that (...) captures a similarity relation over states. This added structure is manifested in payoffs that reward approximate coordination between sender and receiver as well as perfect coordination. I evolve these games using a variation of Herrnstein reinforcement learning that better reflects the generalizing learning strategies real-world actors use in situations where states of the world are similar. In these simulations, signaling can develop very quickly, and the signals are vague in much the way ordinary language predicates are vague—they each exclusively apply to certain items, but for some transition period both signals apply to varying degrees. Moreover, I show that under certain parameter values, in particular when state spaces are large and time is limited, learning generalization of this sort yields strategies with higher payoffs than standard Herrnstein reinforcement learning. These models may then help explain why the phenomenon of vagueness arises in natural language: the learning strategies that allow actors to quickly and effectively develop signaling conventions in contiguous state spaces make it unavoidable.

Twentieth-century analytic philosophy was dominated by positivist antimetaphysics and neo-Humean deflationary metaphysics, and the nature of explanation was reconceived in order to fit these agendas. Unsurprisingly, the explanatory value of theist was widely discredited. I argue that the long-overdue revival of moralized, broadly neo-Aristotelian metaphysics and an improved perspective on modal knowledge dramatically changes the landscape. In this enriched context, there is no sharp divide between physics and metaphysics, and the natural end of the theoretician’s quest for a unified explanation (...) of the universe is God, an absolutely necessary, transcendent, and personal source of all contingent reality.

Why do minority groups tend to be discriminated against when it comes to situations of bargaining and resource division? In this paper, I explore an explanation for this disadvantage that appeals solely to the dynamics of social interaction between minority and majority groups---the cultural Red King effect. As I show, in agent-based models of bargaining between groups, the minority group will tend to get less as a direct result of the fact that they frequently interact with majority group members, while (...) majority group members meet them only rarely. This effect is strengthened by certain psychological phenomenon---risk aversion and in-group preference---is robust on network models, and is strengthened in cases where pre-existing norms are discriminatory. I will also discuss how this effect unifies previous results on the impacts of institutional memory on bargaining between groups. (shrink)

Many societies have norms of equity – that those who make symmetric social contributions deserve symmetric rewards. Despite this, there are widespread patterns of social inequity, especially along gender and racial lines. It is often the case that members of certain social groups receive greater rewards per contribution than others. In this article, we draw on evolutionary game theory to show that the emergence of this sort of convention is far from surprising. In simple cultural evolutionary models, inequity is much (...) more likely to emerge than equity, despite the presence of stable, equitable outcomes that groups might instead learn. As we outline, social groups provide a way to break symmetry between actors in determining both contribution and reward in joint projects. (shrink)

I Introduction The question of this paper is, what would it be to act with freedom of the will? What kind of control is inchoately in view when we speak, pretheoretically, of being ‘self- determining’ beings, of ‘freely making choices in view of consciously considered reasons’ (pro and con) - of its being ‘up to us’ how we shall act? My question here is not whether we have (or have any reason to think we have) such freedom, or what is (...) the most robust account of our freedom compatible with late twentieth-century science. Many contemporary philosophers are all too ready to settle for a deflationary account of freedom and declare victory, with some brief remarks reminding us that we were created a little lower than the angels. I am not so sanguine about the ability of such accounts to leave reasonably intact our judgments about human autonomy, dignity, and responsibility. But, as I’ve said, that’s not my concern here. Instead, I want to revisit the question of what exactly ‘self-determination’, on our ordinary conception, comes to. (shrink)

Using evolutionary game theory, I consider how guilt can provide individual fitness benefits to actors both before and after bad behavior. This supplements recent work by philosophers on the evolution of guilt with a more complete picture of the relevant selection pressures.

A good deal of attention has been given in recent philosophy of religion to the question of whether we can sensibly attribute to God a form of knowledge which the 16th-century Jesuit theologian Luis de Molina termed "middle knowledge". Interest in the doctrine has been spurred by a recognition of its intimate connection to certain conceptions of providence, prophecy, and response to petitionary prayer. According to defenders of the doctrine, which I will call "Molinism", the objects of middle knowledge are (...) all the true counterfactuals of the form, 'If C were to occur, then S would freely do A', where C specifies a particular set of circumstances. (Such propositions are usually referred to as "counterfactuals of freedom" - hereafter "CFs".)' I will try to assess the current status of two distinct questions: (1) Are there true CFs? and (2) Could God know true CFs if there are any? Obviously, Molinism must answer both questions affirmatively. Most of the discussion has focused on the first question. I hope to show that this approach has been a dialectical mistake on the part of critics of Molinism, for the difficulties of giving an affirmative answer to question (2) are, I believe, far easier to state clearly and convincingly.

Given its centrality to the intellectual thought processes through which the great structures of logic, nature, and spirit are unfolded it is clear that mediation is vital to the very possibility of Hegel’s encyclopaedic philosophy. Yet Hegel gives little specific explanation of the concept of mediation. Surprisingly, it has been the subject of even less attention by scholars of Hegel. Nevertheless it is casually used in discussions of Hegel and post- Hegelian philosophy as though its meaning were simple and straightforward. (...) In these discussions mediation is the thesis that meanings are not atomic in that the independence of something is inseparable from its relation to something else. Hence being is mediated by nothing, the particular by the universal, the individual by society. But does Hegel ever explain mediation in a way which justifies such use of the concept? The same easy employment of mediation is found in Theodor Adorno whose works are replete with the use of this concept and, indeed, acknowledgements of its Hegelian origin. But the concept of mediation in Adorno’s negative dialectic is operative in an entirely different context from that of Hegel. How, it might be asked, can a concept be so adaptable? I want to argue that mediation is, in fact, an equivocal term which in both Hegel and Adorno covers a variety of entirely different conceptual relations. Furthermore, as propounded by both Hegel and Adorno it lacks the rigour which could allow the particular conclusions which the concept allegedly facilitates. (shrink)

Social media, meaning digital technologies and platforms such as blogs, wikis, forums, content aggregators, sharing sites, and social networks like Facebook and Twitter, have profoundly changed the way that information can be shared online. Now, almost anyone with a broadband internet connection or a smart phone can share ideas, data, and opinions with just about anyone else on the planet. This change has serious implications for the way in which human subjects research can be conducted and, concomitantly, for the ways (...) in which such research may be regulated. This article explores some of these issues. (shrink)

The hypothetical scenarios generally known as trolley problems have become widespread in recent moral philosophy. They invariably require an agent to choose one of a strictly limited number of options, all of them bad. Although they don’t always involve trolleys / trams, and are used to make a wide variety of points, what makes it justified to speak of a distinctive “trolley method” is the characteristic assumption that the intuitive reactions that all these artificial situations elicit constitute an appropriate guide (...) to real-life moral reasoning. I dispute this assumption by arguing that trolley cases inevitably constrain the supposed rescuers into behaving in ways that clearly deviate from psychologically healthy, and morally defensible, human behavior. Through this focus on a generally overlooked aspect of trolley theorizing – namely, the highly impoverished role invariably allotted to the would-be rescuer in these scenarios – I aim to challenge the complacent twin assumptions of advocates of the trolley method that this approach to moral reasoning has practical value, and is in any case innocuous. Neither assumption is true. (shrink)

Social Media, like Facebook and Twitter, are having a profound effect on the way that human subjects research is being conducted. In light of the changes proposed in ANPRM, in this article I argue that traditional research ethics and regulations may not easily translate to the use of social media in human subjects research. Using the conceptual model of apomediation, which describes the peer-to-peer way in which health information is shared via social media, I suggest that we may need to (...) think again about the suitability of current regulations to deal with social media research.

What makes ethical accounts natural law ethical is, I argue, commonly misrepresented in teaching within much of the philosophical academy. Yet those immersed in the field of natural law and ethics rarely give definitions/brief characterisations of what makes ethical accounts natural law ethical. I suggest theoretical reasons for the lack. I argue that bringing natural law into ethics is best understood as leading to theoretically unitary accounts, not simply collections of positions detachable from each other: an overlooked and significant point (...) when defending natural law ethical accounts. My arguments throughout rely on the metaethical/normative ethical distinction, which is relatively little used in the natural law literature. I argue that the distinction helps clarify what is distinctive of natural law ethical accounts in general, especially to the secular contemporary philosophical academy, where appreciation of natural law ethical accounts is commonly appreciably lower than in philosophical contexts with a religious ethos.

First published in 1975, The Correspondence Theory of Truth examines the simplest statements of empirical fact and establishes what we can mean when we say that such statements are true. In particular, the author has considered whether any or all of beliefs, sentences, statements, or propositions are properly said to be true or false. He proceeds to examine what we mean by the term 'fact' and what possible relation between facts and beliefs could be meant by the term 'correspondence'. The (...) second part of the book is a critical survey of important contemporary accounts of truth. The author examines Tarski's semantic theory to see if it offers a satisfactory reconstruction of the essence of the traditional notion of correspondence, then J.L. Austin's recent and famous version of the correspondence theory and some criticisms of it by Professor P. E. Strawson. A final chapter summarizes the viable content of the correspondence theory and suggests what problems about truth still remain for discussion if the theory is accepted. This book will be an essential read for students and scholars of Philosophy. (shrink)

Noel Hendrickson, in “Against an Agent-Causal Theory of Action” (this volume), carefully and intelligently probes aspects of the agent-causal account of free will I present in Persons and Causes: The Metaphysics of Free Will. The central target of his criticism is my contention that agent-causal events, by their very nature, cannot be caused. Here, I respond to his argument on this point.

Does law matter regarding public health outcomes? Regardless of what one may think about the answer to this age-old question, in recent years the public health community has increasingly demonstrated and recognized the roles that public health laws and policies play in effectuating long-lasting and broad-based population-wide changes. Public health laws and policies have been instrumental in the following ways: reducing smoking prevalence; reducing underage alcohol-related drinking, driving, crashes, and fatalities; reducing exposure to second-hand smoke; eliminating vaccine–associated paralytic poliomyelitis ; (...) increasing seat-belt use and reducing traffic fatalities; reducing dental carries; and reducing access to and consumption of unhealthy foods and beverages sold in schools and to reductions in caloric intake and overweight. In fact, in a review of the ten greatest public health achievements in the 20th century, all were influenced by policy change. (shrink)

The detection and spread of pandemic 2009 H1N1 influenza in the United States led to a complex and multi-faceted response by the public health system that lasted more than a year. When the first domestic case of the virus was detected in California on April 15, 2009, and a second, unrelated case was identified more than 130 miles away in the same state on April 17, 2009, the unique combination of influenza virus genes in addition to its emergence and rapid (...) spread at the end of the typical Northern Hemisphere influenza season suggested the potential for a high morbidity, high mortality event. In response, federal, state, and local public health officials conducted epidemiologic investigations with federal and state laboratory support to help to determine the scope of the H1N1 pandemic. On April 26, the Secretary of the U.S. Department of Health and Human Services declared a public health emergency that was renewed through June 23, 2010. The pandemic that ensued tested virtually every aspect of U.S. public health preparedness and response systems, from laboratory capabilities and capacities to social distancing plans. (shrink)

In Physics I.8, Aristotle outlines and responds to an Eleatic argument against the reality of change. I defend a new reading according to which the argu- ment assumes Predicational Monism, the claim that each being can possess only one property. In Phys. I.2, Aristotle responds to Predicational Monism, which he attributes to the Eleatics; I argue that he uses this response to distinguish coin- cidental from non-coincidental becoming, a distinction he employs in Phys I.8 to resolve the argument against the (...) reality of change. The Eleatics’ acceptance of Predicational Monism, I argue, explains why this distinction is unavailable to them. (shrink)

In the present state of philosophy in the English-speaking world, to choose to talk about sense data may seem perverse. What could be more boring for one's audience than to attempt variations on so threadbare a theme? And worse, what could be more unfashionable in the aftermath of Wittgenstein and Austin? My reasons for selecting this unpromising topic are twofold. First, the general theme of this series of lectures is empiricism. And whatever meanings we put upon that ambiguous word, it (...) is clear that as a matter of history the problems of perception have been important problems for nearly all those philosophers who would consider themselves to be empiricists. And however unsatisfactory sense datum theories of perception may now be held to be, such theories have been central to the empiricist tradition. Secondly, it is important not to be too much impressed by the fact that a particular philosophical opinion is fashionable or unfashionable. The former certainly does not guarantee its truth nor the latter its falsity. It has often been remarked that philosophical opinions are very rarely refuted. Instead they fall out of vogue only to return some years later in another guise. It is perhaps time to take another look at the notion of sense data. The most ingenious and persistent attacks on analyses of perception in terms of sense data have been at best indecisive, as Professor Ayer showed in his reply to Austin's Sense and Sensibilia.

New Zealand fisheries management reforms are being conducted in terms of 'balancing' of interests and reconciliation of conflicting claims over ownership and use. Fisheries legislation seeks efficient levels of fishing effort, while establishing 'environmental bottom lines' for stock conservation; resource management law requires, alongside efficiency of resource use, consideration for species diversity and 'the intrinsic values of ecosystems' ; and the Treaty of Waitangi safeguards customary practices and life-support requirements for the Maori people. This paper analyses these antinomies in terms (...) of contrasting ethical positions – utilitarian rationality, versus an ethic of reciprocal hospitality – and shows how fisheries management policies can be formulated on this basis.
