According to the so-called Hempel’s Dilemma, the thesis of physicalism is either false or empty. Our intention in this paper is not to propose a solution to the Dilemma, but rather to argue as follows: to the extent that Hempel’s Dilemma applies to physicalism it equally applies to any theory that gives a deep-structure and changeable account of our experience or of high-level theories. In particular, we will show that it also applies to mind-body dualistic (...) theories. The scope of Hempel’s Dilemma turns out to be very wide: it is a special case of a general sceptical argument against changeable deep-structure theories in and outside science. (shrink)

In a recent paper, Firt, Hemmo and Shenker argue that Hempel’s dilemma, typically thought to primarily undermine physicalism, is generalizable and impacts mind-body dualism and many other theories equally. I challenge this view and argue that Hempel’s dilemma admits of at least two distinct construals: a general-skeptical construal, underpinned by historically driven arguments such as the pessimistic induction, and a non-skeptical construal, driven by the specific puzzles and volatility of current physics. While the general-skeptical construal applies (...) to all changeable deep-structure theories, the non-skeptical construal primarily targets volatile theories which harbor exclusionary ambitions. As a result, dualism largely evades both construals due to the stability of theories of the mental and their lack of exclusionary ambitions. Conversely, physicalism is uniquely susceptible to both construals due to its strong commitment to deep-structure realism, inherent exclusionary ambitions, and the volatility of certain branches of fundamental physics. The paper ultimately concludes that Hempel’s dilemma is not universally problematic, but presents a unique challenge to physicalism while being relatively congenial to dualism. (shrink)

Physicalism, the thesis that everything is physical, is one of the most controversial problems in philosophy. Its adherents argue that there is no more important doctrine in philosophy, whilst its opponents claim that its role is greatly exaggerated. In this superb introduction to the problem Daniel Stoljar focuses on three fundamental questions: the interpretation, truth and philosophical significance of physicalism. In answering these questions he covers the following key topics: -/- (i)A brief history of physicalism and its definitions, (ii)what a (...) physical property is and how physicalism meets challenges from empirical sciences, (iii)'Hempel’s dilemma’ and the relationship between physicalism and physics, (iv)physicalism and key debates in metaphysics and philosophy of mind, such as supervenience, identity and conceivability, and (v)physicalism and causality. -/- Additional features include chapter summaries, annotated further reading and a glossary of technical terms, making Physicalism ideal for those coming to the problem for the first time.

The disciplinary characterisation (DC) is the most popular approach to defining metaphysical naturalism and physicalism. It defines metaphysical naturalism with reference to scientific theories and defines physicalism with reference to physical theories, and suggests that every entity that exists is a posited entity of these theories. DC has been criticised for its inability to solve Hempel’s dilemma and a list of problems alike. In this paper, I propose and defend a novel version of DC that can be called (...) a historical paths approach. The idea is (roughly) that metaphysical naturalism can be defined with reference to the historical ideas that current scientific ideas descend from. I argue that it is not rendered implausible by the above problems, and hence that DC is more defensible and attractive than it may first appear. I then argue that the approach also provides a useful framework for the naturalisation of the philosophy of mind and phenomenology. (shrink)

Physicalism is the claim that that there is nothing in the world but the physical. Philosophers who defend physicalism have to confront a well-known dilemma, known as Hempel’s dilemma, concerning the definition of ‘the physical’: if ‘the physical’ is whatever current physics says there is, then physicalism is most probably false; but if ‘the physical’ is whatever the true theory of physics would say that there is, we have that physicalism is vacuous and runs the risk of (...) becoming trivial. This article has two parts. The first, negative, part is devoted to developing a criticism of the so-called via negativa response to Hempel’s dilemma. In the second, more substantial, part, I propose to take the first horn of Hempel’s dilemma. However, I argue for a broad construal of ‘current physics’ and characterize ‘the physical’ accordingly. The virtues of the broad characterization of ‘the physical’ are: first, it makes physicalism less likely to be false; and second, it ties our understanding of ‘the physical’ to the reasons we have for believing in physicalism. That is, it fulfills the desideratum of construing our theses according to the reasons we have to believe in them. (shrink)

The acceptance of causal closure has had a profoundly limiting effect on the philosophical treatment of sui generis mental causation in recent decades. Philosophical treatments of special divine action have been likewise hampered by a widespread commitment to closure. If fundamental reality is as closure tells us it is, then nonphysical minds—human and divine— are either causally impotent or redundant. In this paper, I reject this limitation as baseless. Specifically, I will show how Hempel’s dilemma poses a far (...) greater challenge when applied to a causal closure principle than it did to the task of defining physicalism. Reponses to the dilemma can be used to disambiguate closure, but not without significant cost. In light of Hempel’s dilemma, there is no conception of closure that can do all of the following: rule out sui generis mental causation, have a reasonable chance of being true, and avoid problematic circularity. At the end of the day, I maintain that closure, properly understood, is, or ought to be, just one methodological stance among many. If this is correct, it is a stance that a theist can freely reject. (shrink)

In this dissertation, I examine the implications of the problem of mental causation and what David Chalmers has dubbed the “ hard problem of consciousness” for competing accounts of the mind. I begin, in Chapter One, with a critical analysis of Jaegwon Kim’s Physicalism, or Something Near Enough. (2005) There, I maintain that Kim’s ontology cannot adequately address both the problem of mental causation and the “ hard problem of consciousness.” In Chapter Two, I examine the causal pairing problem for (...) substance dualism. I demonstrate both that the substance dualist can respond to the argument at no great cost, and that the pairing problem applies, with equal force, to the irreducible qualia posited on Kim’s account. Chapters Three and Four are devoted to what I take to be the central argument against any kind of dualism: the causal exclusion argument. In Chapter Three, I examine dualistic responses to the exclusion argument that grant the causal closure of the physical world. I note that these responses, though technically adequate, are nevertheless theoretically unpalatable. In addition to requiring the dualist to adopt unconventional attitudes towards causation, responses of this variety also have the unfortunate result of rendering libertarian freedom impossible. Finally, in Chapter Four, I turn my attention to the question of causal closure. I maintain that the causal closure of the physical world, though widely affirmed, is nevertheless extraordinarily difficult to support. In light of Hempel’s Dilemma, causal closure is either false, compatible with dualistic interaction, or unacceptably stipulative. There is, I maintain, no causal closure principle up to the tasks required by the causal exclusion argument. For that reason, I conclude that the dualist ought not to worry about causal closure.

As these opening quotes acknowledge, the Prisoner’s Dilemma (PD) represents a core puzzle within the formal mathematics of game theory.3 Its rise in conspicuity is evident figure 2.1 above demonstrating a relatively steady rise in incidences of the phrase’s usage between 1960 to 1995, with a stable presence persisting into the twenty first century. This famous two-person “game,” with a stock narrative cast in terms of two prisoners who each independently must choose whether to remain silent or speak, each (...) advancing self-interest at the expense of the other and thereby achieving a mutually suboptimal outcome, mires any social interaction it is applied to into perplexity. The logic of this game proves the inverse of Adam Smith’s invisible hand: individuals acting on self interest will achieve a mutually suboptimal outcome. However, as this chapter illuminates, the assumptions underlying game theory drive this conclusion. (shrink)

Many philosophers use “physicalism” and “naturalism” interchangeably. In this paper, I will distinguish ontological naturalism from physicalism. While broad versions of physicalism are compatible with naturalism, naturalism doesn't have to be committed to strong versions of physical reductionism, so it cannot be defined as equivalent to it. Instead of relying on the notion of ideal physics, naturalism can refer to the notion of ideal natural science that doesn't imply unity of science. The notion of ideal natural science, as well as (...) the notion of ideal physics, will be vindicated. I will shortly explicate the notion of ideal natural science, and define ontological naturalism based on it. (shrink)

According to Hempel's paradox, evidence (E) that an object is a nonblack nonraven confirms the hypothesis (H) that every raven is black. According to the standard Bayesian solution, E does confirm H but only to a minute degree. This solution relies on the almost never explicitly defended assumption that the probability of H should not be affected by evidence that an object is nonblack. I argue that this assumption is implausible, and I propose a way out for Bayesians.

Robert Nozick, in chapter two of the nature of rationality, proposes two famous problems in decision theory (i.e., Newcomb's problem and Prisoner Dilemma) and two main strategies toward these problems i.e. dominant strategy and dominated or cooperative one.

In this calculation he goes beyond the standard principle of maximizing expected utility and would try to put forth less ideal and more realistic principles that (...) fit the decision situation in the real world.

We make the case that the Prisoner’s Dilemma, notwithstanding its fame and the quantity of intellectual resources devoted to it, has largely failed to explain any phenomena of social scientific or biological interest. In the heart of the paper we examine in detail a famous purported example of Prisoner’s Dilemma empirical success, namely Axelrod’s analysis of WWI trench warfare, and argue that this success is greatly overstated. Further, we explain why this negative verdict is likely true generally and (...) not just in our case study. We also address some possible defenses of the Prisoner’s Dilemma. (shrink)

The paper takes a novel approach to a classic problem—Hempel’s Raven Paradox. A standard approach to it supposes the solution to consist in bringing our inductive logic into “reflective equilibrium” with our intuitive judgements about which inductive inferences we should license. This approach leaves the intuitions as a kind of black box and takes it on faith that, whatever the structure of the intuitions inside that box might be, it is one for which we can construct an isomorphic formal (...) edifice, a system of inductive logic. By popping open the box we can see whether that faith is misplaced. I aim, therefore, to characterize our pre-theoretical, intuitive understanding of generalizations like “ravens are black” and argue that, intuitively, we take them to mean, for instance: “ravens are black by some indeterminate yet characteristic means.” I motivate and explicate this formulation and bring it to bear on Hempel’s Problem.

This paper presents a new analysis of C.G. Hempel’s conditions of adequacy for any relation of confirmation [Hempel C. G. (1945). Aspects of scientific explanation and other essays in the philosophy of science. New York: The Free Press, pp. 3–51.], differing from the one Carnap gave in §87 of his [1962. Logical foundations of probability (2nd ed.). Chicago: University of Chicago Press.]. Hempel, it is argued, felt the need for two concepts of confirmation: one aiming at true hypotheses and (...) another aiming at informative hypotheses. However, he also realized that these two concepts are conflicting, and he gave up the concept of confirmation aiming at informative hypotheses. I then show that one can have Hempel’s cake and eat it too. There is a logic that takes into account both of these two conflicting aspects. According to this logic, a sentence H is an acceptable hypothesis for evidence E if and only if H is both sufficiently plausible given E and sufficiently informative about E. Finally, the logic sheds new light on Carnap’s analysis. (shrink)

Hempel’s Converse Consequence Condition (CCC), Entailment Condition (EC), and Special Consequence Condition (SCC) have some prima facie plausibility when taken individually. Hempel, though, shows that they have no plausibility when taken together, for together they entail that E confirms H for any propositions E and H. This is “Hempel’s paradox”. It turns out that Hempel’s argument would fail if one or more of CCC, EC, and SCC were modified in terms of explanation. This opens up the possibility (...) that Hempel’s paradox can be solved by modifying one or more of CCC, EC, and SCC in terms of explanation. I explore this possibility by modifying CCC and SCC in terms of explanation and considering whether CCC and SCC so modified are correct. I also relate that possibility to Inference to the Best Explanation. (shrink)

Intuitively, many people seem to hold that engaging in acts of virtual murder in videogames is morally permissible, whereas engaging in acts of virtual child molestation is morally impermissible. The Gamer’s Dilemma (Luck in Ethics Inf Technol 11:31–36, 2009) challenges these intuitions by arguing that it is unclear whether there is a morally relevant difference between these two types of virtual actions. There are two main responses in the literature to this dilemma. First, attempts to resolve the (...) class='Hi'>dilemma by defending an account of the relevant moral differences between virtual murder and virtual child molestation. Second, attempts to dissolve the dilemma by undermining the intuitions that ground it. In this paper, we argue that a narrow version of the Gamer’s Dilemma seems to survive attempts to resolve or dissolve it away entirely, since neither approach seems to be able to solve the dilemma for all cases. We thus provide a contextually sensitive version of the dilemma that more accurately tracks onto the intuitions of gamers. However, we also argue that the intuitions that ground the narrow version of the Dilemma may not have a moral foundation, and we put forward alternative non-moral normative foundations that seem to better account for the remaining intuitive difference between the two types of virtual actions. We also respond to proposed solutions to the Gamer’s Dilemma in novel ways and set out areas for future empirical work in this area. (shrink)

English translation of a paper originally published in French in the Canadian Journal of Philosophy under the title 'Comment l'urne de Carter et Leslie se déverse dans celle de Hempel'.

I show thirdly (...) that the Doomsday Argument can be reduced to the core of Hempel's Problem. (shrink)

The Gamer’s Dilemma is based on the intuitions that in single-player video games fictional acts of murder are seen as morally acceptable whereas fictional acts of sexual assault are seen as morally unacceptable. Recently, it has been suggested that these intuitions may apply across different forms of media as part of a broader Paradox of Fictionally Going Too Far. This study aims to empirically explore this issue by determining whether fictional murder is seen as more morally acceptable than fictional (...) sexual assault across different media types, and whether audio-visuality and the degree of agency afforded by the medium influences these judgments. An experimental survey study was developed where participants responded to imaginary fictional scenarios as part of a 2 (engages with fictional murder or fictional sexual assault) X 2 (in a high or low agency) X 2 (audio-visual or non-audio-visual medium) factorial design. It was found that fictional murder was seen to be more morally acceptable than fictional sexual assault across all media types, providing empirical support for the Paradox of Fictionally Going Too Far. It was also found that the audio-visuality and degree of agency influenced judgments of moral acceptability. (shrink)

The Gamer's Dilemma is a much-discussed issue in video game ethics which probes our seemingly conflicting intuitions about the moral acceptability of virtual murder compared to virtual child molestation. But how we approach this dilemma depends on how we frame it. With this in mind, I identify three ways the dilemma has been conceptualized: the Descriptive Gamer's Investigation, which focuses on empirically explaining the source of our intuitions; the Gamer's Puzzle, which uses the dilemma to explore (...) and test moral or metaphysical theories; and the Applied Gamer's Dilemma, which reconstructs the moral commitments underlying the intuitions to provide action-guidance. Clearly distinguishing these framings allows us to identify the distinct methodologies and criteria of success for each approach. This tripartite framework helps resolve confusions in the debate, highlights the need for experimental philosophy to test proposed resolutions, and opens space for a serious reconsideration of consequentialism. The paper thus provides conceptual clarity to move the discussion forward productively. (shrink)

In this paper we argue that Michael Huemer’s phenomenal conservatism—the internalist view according to which our beliefs are prima facie justified if based on how things seems or appears to us to be—doesn’t fall afoul of Michael Bergmann’s dilemma for epistemological internalism. We start by showing that the thought experiment that Bergmann adduces to conclude that is vulnerable to his dilemma misses its target. After that, we distinguish between two ways in which a mental state can contribute to (...) the justification of a belief: the direct way and the indirect way. We identify a straightforward reason for claiming that the justification contributed indirectly is subject to Bergmann’s dilemma. Then we show that the same reason doesn’t extend to the claim that the justification contributed directly is subject to Bergmann’s dilemma. As is the view that seemings or appearances contribute justification directly, we infer that Bergmann’s contention that his dilemma applies to is unmotivated. In the final part, we suggest that our line of response to Bergmann can be used to shield other types of internalist justification from Bergmann’s objection. We also propose that seeming-grounded justification can be combined with justification of one of these types to form the basis of a promising version of internalist foundationalism. (shrink)

The Gamer’s Dilemma refers to the philosophical challenge of justifying the intuitive difference people seem to see between the moral permissibility of enacting virtual murder and the moral impermissibility of enacting virtual child molestation in video games (Luck Ethics and Information Technology, 1:31, 2009). Recently, Luck in Philosophia, 50:1287–1308, 2022 has argued that the Gamer’s Dilemma is actually an instance of a more general “paradox”, which he calls the “paradox of treating wrongdoing lightly”, and he proposes a graveness (...) resolution to this paradox. In response, we argue for four key claims. First, we accept Luck’s expansion of the Gamer’s Dilemma to be applicable to a wider set of media, but give a novel recasting of this in terms of the Paradox of Fictionally Going Too Far. Second, we develop a novel criticism of Luck in Philosophia, 50:1287–1308, 2022 graveness resolution to this broader paradox. Third, we argue that the Paradox of Fictionally Going Too Far helps to expose an implicit moralism in the Gamer’s Dilemma literature when compared to relevant nearby literatures about other forms of media. Fourth, we consider a range of non-moral, cultural and media conventions that plausibly help to dissolve the intuitive moral gap between non-sexual and sexual violence that is central to this paradox.

Peter Baumann offers the tantalizing suggestion that Thomas Reid is almost, but not quite, a pragmatist. He motivates this claim by posing a dilemma for common sense philosophy: Will it be dogmatism or scepticism? Baumann claims that Reid points to but does not embrace a pragmatist third way between these unsavory options. If we understand `pragmatism' differently than Baumann does, however, we need not be so equivocal in attributing it to Reid. Reid makes what we could call an argument (...) from practical commitment, and this is plausibly an instance of what William James calls the pragmatic method. (shrink)

Reid’s dilemma concludes that, whether the idea associated with a denied proposition is lively or faint, Hume is committed to saying that it is either believed or merely conceived. In neither case would there be denial. If so, then Hume cannot give an adequate account of denial. I consider and reject Powell’s suggestion that Hume could have advanced a “Content Contrary” account of denial that avoids Reid’s dilemma. However, not only would a Humean Content Contrary account be viciously (...) circular, textual evidence suggests that Hume did not hold such an account. I then argue that Govier’s distinction between force and vivacity cannot help Hume. Not only did Hume fail to recognize this distinction, we can advance a variant of Reid’s dilemma even if we distinguish force from vivacity. (shrink)

In this paper I start with the familiar accusation that divine command ethics faces a "Euthyphro dilemma". By looking at what Plato’s ’Euthyphro’ actually says, I argue that no such argument against divine-command ethics was Plato’s intention, and that, in any case, no such argument is cogent. I then explore the place of divine commands and inspiration in Plato’s thought more generally, arguing that Plato sees an important epistemic and practical role for both.

In Justification without Awareness (2006), Michael Bergmann presents a dilemma for internalism from which he claims there is “no escape”: The awareness allegedly required for justification is either strong awareness, which involves conceiving of some justification-contributor as relevant to the truth of a belief, or weak awareness, which does not. Bergmann argues that the former leads to an infinite regress of justifiers, while the latter conflicts with the “clearest and most compelling” motivation for endorsing internalism, namely, that for a (...) belief to be justified its truth must not be an accident from the subject’s perspective. Bergmann’s dilemma might initially seem to have the force of a knock-down argument against the classical foundationalist accounts he considers, if not against all forms of internalism. I argue, however, that the weak-awareness horn of Bergmann’s dilemma is unsuccessful. Classical foundationalists can hold on to the main motivation for internalism and avoid a vicious regress of justifiers. (shrink)

Mark Colyvan formulates a puzzle about belief in inconsistent entities. As a scientific realist, Colyvan refers to salient instances of inconsistencies in our best science and demonstrates how an indispensability argument may justify belief in an inconsistent entity. Colyvan’s indispensability argument presents a two-horned dilemma: either scientific realists are committed to the possibility of warranted belief in inconsistent objects, or we have a reductio ad absurdum, bringing realism into a crisis. Firstly, this paper follows Graham Priest by opposing the (...) received characterisation of inconsistent belief as a kind of epistemic hell. Secondly, I challenge the Quinean naturalism that underpins Colyvan’s indispensability argument. Then, I reformulate Colyvan’s argument with a fallible naturalism, better equipped to account for certain problem candidates for inconsistent entities. Finally, I contend that—even if indispensable—an inconsistent entity poses no problem for the scientific realist, who can have justified belief in inconsistent entities. (shrink)

Luck (2009) argues that gamers face a dilemma when it comes to performing certain virtual acts. Most gamers regularly commit acts of virtual murder, and take these acts to be morally permissible. They are permissible because unlike real murder, no one is harmed in performing them; their only victims are computer-controlled characters, and such characters are not moral patients. What Luck points out is that this justification equally applies to virtual pedophelia, but gamers intuitively think that such acts are (...) not morally permissible. The result is a dilemma: either gamers must reject the intuition that virtual pedophelic acts are impermissible and so accept partaking in such acts, or they must reject the intuition that virtual murder acts are permissible, and so abstain from many (if not most) extant games. While the prevailing solution to this dilemma has been to try and find a morally relevant feature to distinguish the two cases, I argue that a different route should be pursued. It is neither the case that all acts of virtual murder are morally permissible, nor are all acts of virtual pedophelia impermissible. Our intuitions falter and produce this dilemma because they are not sensitive to the different contexts in which games present virtual acts. (shrink)

The iterated Prisoner’s Dilemma has become the standard model for the evolution of cooperative behavior within a community of egoistic agents, frequently cited for implications in both sociology and biology. Due primarily to the work of Axelrod (1980a, 198Ob, 1984, 1985), a strategy of tit for tat (TFT) has established a reputation as being particularly robust. Nowak and Sigmund (1992) have shown, however, that in a world of stochastic error or imperfect communication, it is not TFT that finally triumphs (...) in an ecological model based on population percentages (Axelrod and Hamilton 1981), but ‘generous tit for tat’ (GTFT), which repays cooperation with a probability of cooperation approaching 1 but forgives defection with a probability of l/3. In this paper, we consider a spatialized instantiation of the stochastic Prisoner’s Dilemma, using two-dimensional cellular automata (Wolfram, 1984, 1986; Gutowitz, 1990) to model the spatial dynamics of populations of competing strategies. The surprising result is that in the spatial model it is not GIFT but still more generous strategies that are favored. The optimal strategy within this spatial ecology appears to be a form of ‘bending over backwards’, which returns cooperation for defection with a probability of 2/3 - a rate twice as generous as GTFT.

The dilemma mentioned in the title have long been a puzzle to logic. To solve it, it was necessary to make some philosophical decisions. The article provides these decisions and discusses the way to solve the problem.

A prominent argument for internalism appeals to the requirement that justified beliefs not be accidentally true from the subject’s perspective. Bergmann’s dilemma remains the most troublesome obstacle to those who defend internalism in this way. In a word, what is required for a belief to be non-accidental? If we require the subject to justifiably believe that one is aware of something counting in its favor, then a vicious regress results and one is never justified in believing anything. But we (...) cannot require less since beliefs can satisfy any lesser requirements and still be accidental. I argue here that phenomenal conservatism, which appeals to “seemings,” shows a way out of this dilemma. The key is that seemings, via their unique phenomenal character, make their content non-accidental for us simply by our being conscious of them and without our having to reflect on their significance. This is an important step in the larger project of re-envisioning traditional arguments for access internalism as supporting mentalism instead. (shrink)

A common assumption is that the gods define what constitutes a purposeful life. Many followers of the gods are convinced that a purposeful life cannot exist without the gods to guarantee it; hence, denying the gods’ importance is equivalent to acknowledging that life is unpurposeful. Lavelle’s dilemma examines this consensus through the application of what is known as Euthyphro’s dilemma. The supporters of the Lavelle Consensus face a powerful dilemma: either a purposeful life rests on the gods’ (...) arbitrary decisions, or the gods are not the originators of a purposeful life and life is therefore subject to an independent reality. Both horns of the dilemma compromise the need for the gods’ existence or reduce them to dictators without any right to command. Lavelle’s dilemma thus concerns itself with human beings’ freedom and purpose in life. If powerful beings command human beings, then they are not free; if powerful beings dictate purpose in life, then it is ipso facto not human beings’ purpose but their purpose. Thus, either an objective purposeful life exists, leaving science and philosophy to explain the content of this purpose, or a purposeful life is something all human beings are free to create themselves.

This reorientation could shape (...) a more inclusive, equitable political landscape, offering a foundation for Bangladesh’s democratic future. (shrink)

Hobbes postulates a social contract to formalize our collective transition from the state of nature to civil society. The prisoner’s dilemma challenges both the mechanics and the outcome of that thought experiment. The incentives for reneging are supposedly strong enough to keep rational persons from cooperating. This paper argues that the prisoner’s dilemma undermines a position Hobbes does not hold. The context and parameters of the social contract steer it safely between the horns of the dilemma. Specifically, (...) in a setting as hostile as the state of nature, Hobbes’s emphasis on self-interest places a premium on survival, and thereby on adaptability, which then promotes progressive concessions toward peaceful coexistence. This transforms the relevant model of rationality from utility maximization to utility satisficing, thus favoring the pursuit of a mutually satisfactory outcome over that of the best personal outcome. The difference not only obviates the prisoner’s dilemma but also better approximates the state of nature while leaving a viable way out. (shrink)

This article examines the prisoner's dilemma paradox and argues that confessing is the rational choice, despite this probably entailing a less-than-ideal outcome.

Two of the most important ideas in the philosophy of law are the “Coase Theorem” and the “Prisoner’s Dilemma.” In this paper, the authors explore the relation between these two influential models through a creative thought-experiment. Specifically, the paper presents a pure Coasean version of the Prisoner’s Dilemma, one in which property rights are well-defined and transactions costs are zero (i.e. the prisoners are allowed to openly communicate and bargain with each other), in order to test the truth (...) value of the Coase Theorem. In addition, the paper explores what effect (a) uncertainty, (b) exponential discounting, (c) and elasticity have on the behavior of the prisoners in the Coasean version of the dilemma. Lastly, the paper considers the role of the prosecutor (and third-parties generally) in the Prisoner’s Dilemma and closes with some parting thoughts about the complexity of the dilemma. The authors then conclude by identifying the conditions under which the Prisoner’s Dilemma refutes the Coase Theorem. (shrink)

Historically, Nelson Goodman’s paradox involving the predicates ‘grue’ and ‘bleen’ has been taken to furnish a serious blow to Carl Hempel’s theory of confirmation in particular and to purely formal theories of confirmation in general. In this paper, I argue that Goodman’s paradox is no more serious of a threat to Hempel’s theory of confirmation than is Hempel’s own paradox of the ravens. I proceed by developing a suggestion from R. D. Rosenkrantz into an argument for the (...) conclusion that these paradoxes are, in fact, equivalent. My argument, if successful, is of both historical and philosophical interest. Goodman himself maintained that Hempel’s theory of confirmation was capable of handling the paradox of the ravens. And Hempel eventually conceded that Goodman’s paradox showed that there could be no adequate, purely syntactical theory of confirmation. The conclusion of my argument entails, by contrast, that Hempel’s theory of confirmation is incapable of handling Goodman’s paradox if and only if it is incapable of handling the paradox of the ravens. It also entails that for any adequate solution to one of these paradoxes, there is a corresponding and equally adequate solution to the other. (shrink)

During the American Civil Rights Movement, Martin Luther King’s principal arguments reasoned from theological ethics, appealing to natural law, imago Dei, and agape love. Today in the United States, with the prevailing ideal of public reason, such arguments are unacceptable in the public square. In lieu of King’s theological arguments, are there philosophical principles or values adequate to sustain the cause of racial justice, establishing both a secure rational foundation for racial justice and providing sufficient moral incentive for citizens to (...) work self-sacrificially for this cause? I assess the prospects of the major philosophical alternatives, specifically utilitarianism, Kantian ethics, virtue ethics, contractarianism, and the anti-theory option. I conclude that each of these approaches fails to provide the necessary conceptual resources to sustain the cause for racial justice. This presents a disconcerting dilemma: either we readmit theological considerations into the public square or surrender hope for the achievement of lasting racial justice in the United States.

Plea bargains are the stock-in-trade of the modern American prosecutor’s office. The basic scenario, wherein a defendant agrees to plea guilty in exchange for a reduced sentence, is familiar to viewers of police procedurals. In an equally famous variation on the theme, the prosecutor requests something more than an admission of guilt: leniency will only be forthcoming if the defendant is willing to cooperate with the prosecutor in securing the conviction of another suspect. In some of these cases, the defendant (...) is a low-level criminal who has information on a high-level malefactor who is of more interest to the police. In others, the defendant and the person she is asked to testify against are of the same criminal rank, but evidentiary weaknesses induce the prosecutor to seek the aid of one suspect in order to convict the other. In this latter version, the classic tactic of film detectives is to offer the bargain to both defendants in the hopes that one will crack and agree to reveal what he knows about the other. The defendants could either be in custody for different crimes or be accomplices in the same offense. -/- The last variation (involving accomplices) is the subject of this Article. I take issue with the prosecutorial tactics in these cases because of the risk they create of punishing the comparatively virtuous person more than the comparatively vicious one for the same acts. As I will argue, it is the less honest person who is more likely to accept the prosecutor’s deal, leading the more honest person, who resisted temptation, to suffer greater penalties. -/- I contend that this scenario offends distributive justice, runs counter to the idea (accepted by some) that a proper goal of the state is the cultivation of good character in the citizenry, and is perverse insofar as a person will suffer more from the prosecutor's dilemma insofar as she is more or less a person of conscience. These negative considerations notwithstanding, I do not call for the abolition of accomplice plea bargaining but argue that the problems I raise should be considered when weighing its pros and cons. -/- This article was published in the company of a strong critical response by Guha Krishnamurthi, whose contribution I greatly appreciate.

The Gamer’s Dilemma consists of three intuitively plausible but conflicting assertions: (i) Virtual murder is morally permissible. (ii) Virtual child molestation is morally forbidden. (iii) There is no relevant moral difference between virtual murder and virtual child molestation in computer games. Numerous attempts to resolve (or dissolve) the Gamer’s Dilemma line the field of computer game ethics. Mostly, the phenomenon is approached using expressivist argumentation: Reprehensible virtual actions express something immoral in their performance but are not immoral by (...) themselves. Consequentialists, on the other hand, claim that the immorality of virtual actions arises from their harmful consequences. I argue that both approaches have serious difficulties meeting the moral challenge posed by the Gamer’s Dilemma. They tend to confuse the morality of in-game actions either with the morality of their real-world counterparts or with the morality of games as objects. Following this critical analysis, I will develop a Kantian argument and defend it against two objections. So far, deontological responses to the Gamer’s Dilemma have been sought in vain. Yet, with Kant, its moral challenge can be met by looking at the gamer’s reasons. From this perspective, the Gamer’s Dilemma is based on a false assumption: the moral status of gaming acts does not derive from a normative equation with their real-world counterparts but only from their justifications.

Richard Wollheim threatened George Dickie's institutional definition of art with a dilemma which entailed that the theory is either redundant or incomprehensible and useless. This article modifies the definition to avoid such criticism. First, it shows that the definition's concept of the artworld is not vague when understood as a conventional system of beliefs and practices. Then, based on Gaut's cluster theory, it provides an account of reasons artworld members have to confer the status of a candidate for appreciation. (...) An authorised member of an artworld has a good reason to confer the status on an object if it satisfies a subset of criteria respected as sufficient within this artworld. The first horn of the dilemma is averted because explaining the reasons behind conferral cannot eliminate references to the institution, and the second loses its sharpness, as accepting partial arbitrariness of the conferral does not deprive the theory of its explanatory power.

Amongst those who feel the pull of the truthmaker principle (that truths require for their truth a truthmaker to exist), there is disagreement as to whether it applies to all truths or merely to some distinguished subset. Those in the latter camp, the non-maximalists, argue that there are no ducks in my bath is true not because of something’s existence, but because of the lack of ducks in my bath. Maximalists, by contrast, insist that truths are made true by something’s (...) existence, and so appear to be committed to strange ‘negative’ entities in their ontology. As a consequence, non-maximalists appear to have a more common-sense ontology than maximalists. But things are not so straightforward. I will argue that if maximalism is committed to strange entities then so is non-maximalism; and if non-maximalism can do without strange entities, then so can maximalism. Either way, the non-maximalist has no ontological advantage over the maximalist. (shrink)

This article introduces a strategic decision-game theoretic approach, the Pardoner’s Dilemma, and juxtaposes it with the Prisoner’s Dilemma. Game theory has emerged as a significant approach in the twentieth century for explaining strategic decision-making in numerous arenas, including economics, business, politics, ethics, international relations, biology, law, and war studies. ‘Game theory’ explains how and why players/actors/agents cooperate or conflict to procure their self-interests in a social world. Life is a game, and human, corporate, and artificial intelligent agents are (...) players who play different games to maximise utility or minimise disutility. The Prisoner’s Dilemma is a promising game-theoretic approach that explains strategic decision-making in zero-sum and non-zero-sum games. ‘Strategic decision-making’ means that the outcome does not depend upon the actions of a player but upon all players. There are numerous essential game strategies, including tossing, negotiation, bargaining, balloting, competition, chance, power, and arbitration. Although the Prisoner’s Dilemma is a good game-theoretic approach, it does not allow players to use the key game strategies. In contrast, Pardoner’s Dilemma is a game theoretic approach that not only explains zero-sum and non-zero-sum games but also allows the players to use different game strategies, such as negotiation, bargaining, tossing, chance, balloting, competition, arbitration, and power. The article develops and defends the Pardoner’s Dilemma in the game-theoretic approach as an alternative to the Prisoner’s Dilemma. The article claims that the Pardoner’s Dilemma is a more promising approach than the Prisoner’s Dilemma in the decision-game theoretic framework. By introducing the Pardoner’s Dilemma, the article enhances the scope of decision/game theory in social sciences. (shrink)

Evolutionary applications of game theory present one of the most pedagogically accessible varieties of genuine, contemporary theoretical biology. We present here Oyun (OY-oon, http://charlespence.net/oyun), a program designed to run iterated prisoner’s dilemma tournaments, competitions between prisoner’s dilemma strategies developed by the students themselves. Using this software, students are able to readily design and tweak their own strategies, and to see how they fare both in round-robin tournaments and in “evolutionary” tournaments, where the scores in a given “generation” directly (...) determine contribution to the population in the next generation. Oyun is freely available, runs on Windows, Mac, and Linux computers, and the process of creating new prisoner’s dilemma strategies is both easy to teach and easy for students to grasp. We illustrate with two interesting examples taken from actual use of Oyun in the classroom. (shrink)

Medical ethics is a branch of applied ethics that is deeply connected with the philosophy of medicine. Medical ethics mainly focuses on the moral issues of medicine. It also deals with the problems of euthanasia, abortion, clinical trials, health care and well-being. There are many approaches or moral theories inside applied ethics. They give moral reasons for medic’s actions, especially in difficult or controversial situations. Among the numerous contemporary ethical theories, the theory of realism by English philosopher Philippa Foot takes (...) a particular place. Her theory of moral realism has been formed under the influence of Aristotle and Tomas Aquinas’ ethics. (shrink)
