ABSTRACT: The conclusions on libertarianism Robert Nozick reaches are appropriate for a bygone era. In a modern market economy, libertarianism requires that employable people have the option of taking up a publicly provided income instead of employment. This is the only way to compensate the involuntarily unemployed that a market economy requires and to ensure that all employment is voluntary. Taxation on voluntary exchanges is unobjectionable because it alters prices, not property, and no one has a right to a particular (...) price. The best way to provide state incomes for the capable unemployed is through a negative income tax.RÉSUMÉ: Les conclusions de libertarisme que tire Nozick valent pour une époque révolue.

In ‘The ethics of belief and Christian faith as commitment to assumptions’, Rik Peels attacks the views that I advanced in ‘Christianity and the ethics of belief’. Here, I rebut his criticisms of the claim that it is wrong to believe without sufficient evidence, of the contention that Christians are committed to that claim, and of the notion of that faith is not belief but commitment to assumptions in the hope of salvation. My original conclusions still stand.

It is morally negligent or reckless to believe without sufficient evidence. The foregoing proposition follows from a rule that is a modified expression of W. K. Clifford's ethics of belief. Clifford attempted to prove that it is always wrong to believe without sufficient evidence by advancing a doxastic counterpart to an act utilitarian argument. Contrary to various commentators, his argument is neither purely nor primarily epistemic, he is not a non-consequentialist, and he does not use stoicism to make his case. (...) Clifford's conclusion is a universal generalisation that is in a precarious position because of potential counterexamples. But the counterexamples do not preclude a rule against going beyond the available evidence and it is worthwhile making a moral case for such a rule. (shrink)

It seems impossible that organisms selected to maximize their genetic legacy could also be moral agents in a world in which taking risks for strangers is sometimes morally laudable. Brian Zamulinski argues that it is possible if morality is an evolutionary by-product rather than an adaptation.Evolutionary Intuitionism presents a new evolutionary theory of human morality. Zamulinski explains the evolution of foundational attitudes, whose relationships to acts constitute moral facts. With foundational attitudes and the resulting moral facts in (...) place, he shows how they ground a plausible normative morality, give answers to meta-ethical questions, and provide an account of moral motivation. He explains the nature of moral intuitions and, thus, of our access to the moral facts. He shows that the theory makes confirmed empirical predictions, including the observable variation in moral views. The combination of intuitionism and evolutionary ethics enables Zamulinski to overcome the standard objections to both.Evolutionary Intuitionism is a unified theory of human morality that explains how an objective morality could develop naturally in a physical world like ours, among organisms like us.

The ethics of belief does not justify condemning all possible forms of religion even in the absence of evidence for any of them or the presence of evidence against all of them. It follows that attacks on religion like the recent one by Richard Dawkins must fail. The reason is not that there is something wrong with the ethics of belief but that Christian faith need not be a matter of beliefs but can instead be a matter of assumptions to (...) which the faithful person is committed. It follows that Christianity can be compatible with scientific rationality. (shrink)

Most evil is compatible with the existence of God if He has an aim that He can achieve only by using an unguided process of evolution and if He cannot be condemned for trying to achieve His aim. It is argued that there is an aim that could reasonably be attributed to God and that God cannot achieve it without using evolution. There are independent grounds for thinking an evolutionary response is necessary if God is to be defended at all. (...) Issues that require further investigation are pointed out and desirable features of the evolutionary response indicated. (shrink)

There is a case to be made for the contention that it is a virtue to have a disposition to try to conform to W. K. Clifford’s ethics of belief. The arguments are not Clifford’s own but new deductive ones. There is also a discussion of some recent criticisms of Clifford. They seldom succeed against Clifford’s original position and never succeed against the case for the Cliffordian virtue. It is pointed out that there need be no conflict between religion and (...) Cliffordianism. The virtue approach emphasizes the value of striving over the value of success. (shrink)

This is an attempt to rehabilitate W. K. Clifford’s long-rejected position that “it is [morally] wrong, always, everywhere, and for anyone, to believe anything on insufficient evidence.” I supplement Clifford’s own argument with two others. They are all valid. I argue for the truth of their premises. The premises in the arguments I use to supplement Clifford’s own are that we cannot believe purely at will; that we must choose among Cliffordianism, some other rule, and doxastic amoralism; that all other (...) rules are self-subverting in that they can be used effectively at most once; and that a policy of doxastic amoralism has worse results overall than adherence to Cliffordianism. The upshot is that Cliffordianism is an irreducible analogue of rule utilitarianism. I look at some objections to Cliffordianism. I argue that none has merit. I point out that Cliffordianism provides something of a justification for legal freedom of conscience. (shrink)

This paper re-evaluates W.K. Clifford on the ethics of belief in light of criticism due to William James and replies to James from David A. Hollinger.

There is an alternative to the type of moral standing that hypothetically supervenes on other, base or subvenient, properties. Attributed moral standing results when people who have a naturally selected belief that they are worthy of moral consideration negotiate with others with the aim of being acknowledged as having moral standing and are successful. They could successfully negotiate with people who possessed supervenient moral standing. In a hypothetical evolutionary competition with the latter, they would replace them entirely. The result would (...) be a moral community that excludes animals but that includes human infants. Membership in the moral community ends up being what it would be if moral standing supervened on the property of being human. The supervenience doctrine is also criticized on other grounds. (shrink)

The main claim here is that Aquinas’s theory of natural law is false because it is incompatible with the occurrence of evolution by variation and natural selection. This contradicts the Thomist opinion that there is no conflict between the two. The conflict is deep and pervasive, involving the core elements of Aquinas’s theory. The problematic elements include: 1) the fundamental precept that good should be done and pursued, and evil avoided; 2) the claim that every organism aims at the good (...) and that it is wrong to frustrate nature; 3) the Aristotelian preconception that everything has a single preeminent end; 4) the putative natural inclinations attributed to human beings; 5) the assumption that species essentialism is true; and 6) the notion that God’s intentions are discernible in the natural world. It is concluded that the problems are so extensive that Aquinas’s theory is beyond rescue. (shrink)

We know that someone is a hypocrite when he acts inconsistently with his purported beliefs. Understanding how we know it is an essential aspect of understanding the nature of belief. We can recognize the phenomenon when beliefs are ‘inscribed’ in the brain, there is a disposition to maintain consistency among the propositions represented by the ‘inscriptions’, and the inscriptions and the disposition give rise to derivative disinclinations. Since the disinclinations ought to prevent certain actions, we notice the conflict between the (...) beliefs hypocrites affirm and the actions they perform. ‘Inconsistency’ is a short-hand description for the conflict. Derivative disinclinations differ from dispositions in several ways and objections to the latter are not transferable to the former. The account not only explains how we can recognize hypocrisy but is also compatible with most truisms about the nature of belief. Where it is not, the truisms can be explained away as understandable errors. (shrink)

This is a new argument to the effect that religions are not truth-oriented. In other words, it is not a fundamental function of religion to represent the world accurately. I compare two hypotheses with respect to their likelihood. The one which entails that religion is not truth-oriented is a better explanation than its competitor for a number of empirical observations about religion. It is also at least as probable. I point out that, once one has established that religions are not (...) truth-oriented, it is possible to argue that religions are false and it is possible to run a sound ad hominem argument against religious believers who advance religious claims. I suggest that the results are early ones and that what matters is evaluating religion in the way I illustrate in this paper. The ad hominem argument shows that the question of whether religion is truth-oriented is particularly important. (shrink)

In reply to Mawson, I accept that each and every religion includes the self-referential belief that it is true. I seek to show that this admission does not entail that the rest of the beliefs of religions track the truth or that they are not better explained through the religion-as-fiction hypothesis. If that hypothesis is well-grounded, it gives us good reason not to take arguments for religions' non-self-referential beliefs seriously. (Published Online August 11 2004).

Michael Scott attacks my use of likelihood in assessing two explanations for human religion. He assumes that I rely on likelihood alone. He is attacking a straw man. We have no alternative but to rely on likelihood when the probabilities of two competing hypotheses are identical, as I charitably assumed with respect to the hypotheses I discussed. His other criticisms likewise miss the mark.

This paper provides a comment on Brian Zamulinksi's article in Religious Studies, 39 , 43–60. Contrary to Zamulinski's claim that religions are not truth-oriented but function as fictions, it is contended that they could not serve the purpose he assigns them unless their adherents regarded them as true. Religions must therefore be truth-oriented. The substantive question is whether any of them are true, and Zamulinski's paper provides no new method for addressing this question.

Authors have a lot of leeway with regard to what they can make true in their story. In general, if the author says that p is true in the fiction we’re reading, we believe that p is true in that fiction. And if we’re playing along with the fictional game, we imagine that, along with everything else in the story, p is true. But there are exceptions to these general principles. Many authors, most notably Kendall Walton and Tamar Szabó Gendler, (...) have discussed apparent counterexamples when p is “morally deviant”. Many other statements that are conceptually impossible also seem to be counterexamples. In this paper I do four things. I survey the range of counterexamples, or at least putative counterexamples, to the principles. Then I look to explanations of the counterexamples. I argue, following Gendler, that the explanation cannot simply be that morally deviant claims are impossible. I argue that the distinctive attitudes we have towards moral propositions cannot explain the counterexamples, since some of the examples don’t involve moral concepts. And I put forward a proposed explanation that turns on the role of ‘higher-level concepts’, concepts that if they are satisfied are satisfied in virtue of more fundamental facts about the world, in fiction, and in imagination.

Normative Externalism argues that it is not important that people live up to their own principles. What matters, in both ethics and epistemology, is that they live up to the correct principles: that they do the right thing, and that they believe rationally. This stance, that what matters are the correct principles, not one's own principles, has implications across ethics and epistemology. In ethics, it undermines the ideas that moral uncertainty should be treated just like factual uncertainty, that moral ignorance (...) frequently excuses moral wrongdoing, and that hypocrisy is a vice. In epistemology, it suggests we need new treatments of higher-order evidence, and of peer disagreement, and of circular reasoning, and the book suggests new approaches to each of these problems. Although the debates in ethics and in epistemology are often conducted separately, putting them in one place helps bring out their common themes. One common theme is that the view that one should live up to one's own principles looks less attractive when people have terrible principles, or when following their own principles would lead to riskier or more aggressive action than the correct principles. Another common theme is that asking people to live up to their principles leads to regresses. It can be hard to know what action or belief complies with one's principles. And now we can ask, in such a case should a person do what they think their principles require, or what their principles actually require? Both answers lead to problems, and the best way to avoid these problems is to simply say people should follow the correct principles. (shrink)

We provide a new interpretation of Zeno’s Paradox of Measure that begins by giving a substantive account, drawn from Aristotle’s text, of the fact that points lack magnitude. The main elements of this account are (1) the Axiom of Archimedes which states that there are no infinitesimal magnitudes, and (2) the principle that all assignments of magnitude, or lack thereof, must be grounded in the magnitude of line segments, the primary objects to which the notion of linear magnitude applies. Armed (...) with this account, we are ineluctably driven to introduce a highly constructive notion of (outer) measure based exclusively on the total magnitude of potentially infinite collections of line segments. The Paradox of Measure then consists in the proof that every finite or potentially infinite collection of points lacks magnitude with respect to this notion of measure. We observe that the Paradox of Measure, thus understood, troubled analysts into the 1880’s, despite their knowledge that the linear continuum is uncountable. The Paradox was ultimately resolved by Borel in his thesis of 1893, as a corollary to his celebrated result that every countable open cover of a closed line segment has a finite sub-cover, a result he later called the “First Fundamental Theorem of Measure Theory.” This achievement of Borel has not been sufficiently appreciated. We conclude with a metamathematical analysis of the resolution of the paradox made possible by recent results in reverse mathematics. (shrink)

Scientific Essentialism defends the view that the fundamental laws of nature depend on the essential properties of the things on which they are said to operate, and are therefore not independent of them. These laws are not imposed upon the world by God, the forces of nature or anything else, but rather are immanent in the world. Ellis argues that ours is a dynamic world consisting of more or less transient objects which are constantly interacting with each other, and whose (...) identities depend on their roles in these processes. Natural objects must behave as they do, because to do otherwise would be contrary to their natures. The laws of nature are, therefore, metaphysically necessary, and consequently, there are necessary connections between events. Brian Ellis calls for the rejection of the theory of Humean Supervenience and an implementation of a new kind of realism in philosophical analysis. (shrink)

The relation between the Greek and Judeo-Christian traditions is "the great problem" of Western philosophy, according to Emmanuel Levinas. In this book Brian Schroeder, Silvia Benso, and an international group of philosophers address the relationship between Levinas and the world of ancient thought. In addition to philosophy, themes touching on religion, mythology, metaphysics, ontology, epistemology, ethics, and politics are also explored. The volume as a whole provides a unified and extended discussion of how an engagement between Levinas and thinkers (...) from the ancient tradition works to enrich understandings of both. This book opens new pathways in ancient and modern philosophical studies as it illuminates new interpretations of Levinas' ethics and his social and political philosophy. (shrink)

We live in a world of crowds and corporations, artworks and artifacts, legislatures and languages, money and markets. These are all social objects — they are made, at least in part, by people and by communities. But what exactly are these things? How are they made, and what is the role of people in making them? In The Ant Trap, Brian Epstein rewrites our understanding of the nature of the social world and the foundations of the social sciences. Epstein (...) explains and challenges the three prevailing traditions about how the social world is made. One tradition takes the social world to be built out of people, much as traffic is built out of cars. A second tradition also takes people to be the building blocks of the social world, but focuses on thoughts and attitudes we have toward one another. And a third tradition takes the social world to be a collective projection onto the physical world. Epstein shows that these share critical flaws. Most fundamentally, all three traditions overestimate the role of people in building the social world: they are overly anthropocentric. Epstein starts from scratch, bringing the resources of contemporary metaphysics to bear. In the place of traditional theories, he introduces a model based on a new distinction between the grounds and the anchors of social facts. Epstein illustrates the model with a study of the nature of law, and shows how to interpret the prevailing traditions about the social world. Then he turns to social groups, and to what it means for a group to take an action or have an intention. Contrary to the overwhelming consensus, these often depend on more than the actions and intentions of group members. (shrink)

What does an Alaskan look like? When asked to visualize someone from Alaska, the image most people conjure up is one of a face lost in a parka, surrounded by snow. Missing from this image is the vibrant diversity of those who call themselves Alaskans, as well as the true essence of the place. Brian Adams, a rising star in photography, aims to change all this with his captivating new collection, I Am Alaskan. In this full-color tribute, Adams entices (...) us to reconsider our ideas of this unique and compelling land and its equally individual residents. He captures subjects on urban streets and in rural villages, revealing what daily life in Alaska is really like. The portraits focus on moments both ordinary and extraordinary, serious and playful, while capturing Alaskans at their most natural. Subjects range from Alaska Native villagers to rarely seen portraits of famous Alaskans, including Sarah Palin, Vic Fischer, and Lance Mackey. Through photographs, Adams also explores his own half-Iñupiat, half-American Alaska identity in the process, revealing how he came to define himself and the state in which he lives. Frame by frame, Adams powerfully and honestly shows what it means to be an Alaskan. (shrink)

"Brian Orend's The Morality of War promises to become the single most comprehensive and important book on just war for this generation. It moves far beyond the review of the standard just war categories to deal comprehensively with the new challenges of the conflict with terrorism. It thoughtfully reviews every major military conflict of the past few decades, mining them for implications of the evolving tradition of just war thinking. It concludes with a critical engagement with the major alternatives (...) to just war thinking: pacifism and 'realism.' It is, in short, the most comprehensive and thoughtful assessment of all aspects of just war since Michael Walzer's classic Just and Unjust Wars." - Martin L. Cook, United States Air Force Academy.

Abstract Kant claims that the basis of a judgment of taste is a merely subjective representation and that the only merely subjective representations are feelings of pleasure or displeasure. Commentators disagree over how to interpret this claim. Some take it to mean that judgments about the beauty of an object depend only on the state of the judging subject. Others argue instead that, for Kant, the pleasure we take in a beautiful object is best understood as a response to its (...) qualities, and that, accordingly, feelings of pleasure or displeasure are no different from other representations, such as colors or smells. While I agree that the judgment of taste is best understood as asserting a claim about an object's qualities, I argue that the distinction Kant makes between feelings of pleasure or displeasure and other representations should not be ignored. I show that one's liking or disliking for an object is merely subjective in the sense that its significance depends on what one has made of oneself through one's aesthetic education. The judgment of taste, then, is merely subjective because one must first become the kind of person whose feelings have the right significance at the right time before one can determine whether an object's qualities make it beautiful.

When making substituted judgments for incapacitated patients, surrogates often struggle to guess what the patient would want if they had capacity. Surrogates may also agonize over having the (sole) responsibility of making such a determination. To address such concerns, a Patient Preference Predictor (PPP) has been proposed that would use an algorithm to infer the treatment preferences of individual patients from population-level data about the known preferences of people with similar demographic characteristics. However, critics have suggested that even if such (...) a PPP were more accurate, on average, than human surrogates in identifying patient preferences, the proposed algorithm would nevertheless fail to respect the patient’s (former) autonomy since it draws on the ‘wrong’ kind of data: namely, data that are not specific to the individual patient and which therefore may not reflect their actual values, or their reasons for having the preferences they do. Taking such criticisms on board, we here propose a new approach: the Personalized Patient Preference Predictor (P4). The P4 is based on recent advances in machine learning, which allow technologies including large language models to be more cheaply and efficiently ‘fine-tuned’ on person-specific data. The P4, unlike the PPP, would be able to infer an individual patient’s preferences from material (e.g., prior treatment decisions) that is in fact specific to them. Thus, we argue, in addition to being potentially more accurate at the individual level than the previously proposed PPP, the predictions of a P4 would also more directly reflect each patient’s own reasons and values. In this article, we review recent discoveries in artificial intelligence research that suggest a P4 is technically feasible, and argue that, if it is developed and appropriately deployed, it should assuage some of the main autonomy-based concerns of critics of the original PPP. We then consider various objections to our proposal and offer some tentative replies. (shrink)

This article argues that, in public and policy contexts, the ways in which many scientists talk about uncertainty in simulations of future climate change not only facilitates communications and cooperation between scientific and policy communities but also affects the perceived authority of science. Uncertainty tends to challenge the authority of chmate science, especially if it is used for policy making, but the relationship between authority and uncertainty is not simply an inverse one. In policy contexts, many scientists are compelled to (...) talk about uncertainty but do not wish to imply that uncertainty is a serious challenge to the authority of scientific knowledge or to its substantial use in policy making. "Boundary-ordering devices, " the contextual discursive attempts to reconcile uncertainty and authority in science, depend critically for their success on their "dual" interpretation: at a general level across a boundary and differently on either side of it. The authors empirically identify a range of such boundary-ordering devices in the climate field. (shrink)

We use a public-good experiment to analyze behavior in a decentralized asymmetric punishment institution. The institution is asymmetric in the sense that players differ in the effectiveness of their punishment. At the aggregate level, we observe remarkable similarities between outcomes in asymmetric and symmetric punishment institutions. Controlling for the average punishment effectiveness of the institutions, we find that asymmetric punishment institutions are as effective in fostering cooperation and as efficient as symmetric institutions. At the individual level, we find that players (...) with higher punishment effectiveness contribute similar amounts to the public account, but have higher earnings and punish more than their weak counterparts.

Among politicians and policy-makers it is almost universally assumed that more transparency in government is better. Until now, philosophers have almost completely ignored the topic of transparency, and when it is discussed there seems to be an assumption that increased transparency is a good thing, which results in no serious attempt to justify it. In this book Brian Kogelmann shows that the standard narrative is false and that many arguments in defence of transparency are weak. He offers a comprehensive (...) philosophical analysis of transparency in government, examining both abstract normative defences of transparency, and transparency's role in the theory of institutional design. His book shows that even when the arguments in favour of transparency are compelling, the costs associated with it are just as forceful as the original arguments themselves, and that strong arguments can be made in defence of more opaque institutions.

Thomas Aquinas was one of the greatest Western philosphers and one of the greatest theologians of the Christian church. In this book we at last have a modern, comprehensive presentation of the total thought of Aquinas. Books on Aquinas invariably deal with either his philosophy or his theology.

It introduces the full range of Aquinas' thinking; (...) and it relates his thinking to writers both earlier and later than Aquinas himself. (shrink)

Trading on non-public material information is fertile ground for a discussion of ethical behavior. The long-running legal tug-of-war over what constitutes illegal insider trading delivers challenges to regulatory authorities charged with detecting and enforcing the law, and is likely one of the reasons that prosecution of insider trading events remains rather uncommon. One can observe both increased volume in the equity and option markets and run-ups in the stock price prior to the announcement of the acquisitions; however, the detection of (...) illegal or unethical insider trading can be difficult. Given the legal uncertainty around insider trading and the circumstantial evidence from the trading activity, it is almost impossible to identify unethical insider trades unless there is a whistleblower or trades are large in size and impeccable in timing. Using call option trading around two merger announcements with similar firms that resulted in different ultimate treatment from the SEC, we illustrate the struggle regulators and prosecutors have with identifying and enforcing unethical insider trades.

Kaplan (1989a) insists that natural languages do not contain displacing devices that operate on character—such displacing devices are called monsters. This thesis has recently faced various empirical challenges (e.g., Schlenker 2003; Anand and Nevins 2004). In this note, the thesis is challenged on grounds of a more theoretical nature. It is argued that the standard compositional semantics of variable binding employs monstrous operations. As a dramatic first example, Kaplan’s formal language, the Logic of Demonstratives, is shown to contain monsters. For (...) similar reasons, the orthodox lambda-calculus-based semantics for variable binding is argued to be monstrous. This technical point promises to provide some far-reaching implications for our understanding of semantic theory and content. The theoretical upshot of the discussion is at least threefold: (i) the Kaplanian thesis that “directly referential” terms are not shiftable/bindable is unmotivated, (ii) since monsters operate on something distinct from the assertoric content of their operands, we must distinguish ingredient sense from assertoric content (cf. Dummett 1973; Evans 1979; Stanley 1997), and (iii) since the case of variable binding provides a paradigm of semantic shift that differs from the other types, it is plausible to think that indexicals—which are standardly treated by means of the assignment function—might undergo the same kind of shift.

For a long time before the ‘climategate’ emails scandal of late 2009 which cast doubt on the propriety of science underpinning the Intergovernmental Panel on Climate Change, attention to climate change science and policy has focused solely upon the truth or falsity of the proposition that human behaviour is responsible for serious global risks from anthropogenic climate change. This article places such propositional concerns in the perspective of a different understanding of the relationships between scientific knowledge and public policy issues (...) from the conventional ‘translation’ model, in which prior scientific research and understanding is communicated and translated into corresponding policies — or not, if it remains disputed and overly uncertain. Explaining some of the key contingencies and bases for uncertainty in IPCC climate projections and human influences, I show how social and technical analysis of climate science is not about denial of the scientific propositional claims at issue, but about understanding the conditional and essentially ambiguous epistemic character of any such knowledge, however technically sophisticated and robust it may be. Contrary to conventional wisdom, it is entirely plausible that existing scientific representations of climate change and its human causes may understate the risks induced by prevailing social-economic processes rather than exaggerate them. As the article shows, the public meanings given to climate science, and to ‘the climate problem’, and thus also the public culture which that knowledge is supposed to inform, are themselves already in key respects presumed and imposed by the science and its framing. This gives rise to perverse effects on public readiness to take informed democratic responsibility for ‘the global climate problem’, and associated cross-cutting issues which existing scientific framings of public policy erase from view.

Background: Recent literature on addiction and judgments about the characteristics of agents has focused on the implications of adopting a ‘brain disease’ versus ‘moral weakness’ model of addiction. Typically, such judgments have to do with what capacities an agent has (e.g., the ability to abstain from substance use). Much less work, however, has been conducted on the relationship between addiction and judgments about an agent’s identity, including whether or to what extent an individual is seen as the same person after (...) becoming addicted. Methods: We conducted a series of vignette-based experiments (total N = 3,620) to assess lay attitudes concerning addiction and identity persistence, systematically manipulating key characteristics of agents and their drug of addiction. Conclusions: In Study 1, we found that US participants judged an agent who became addicted to drugs as being closer to ‘a completely different person’ than ‘completely the same person’ as the agent who existed prior to the addiction. In Studies 2-6, we investigated the intuitive basis for this result, finding that lay judgments of altered identity as a consequence of drug use and addiction are driven primarily by perceived negative changes in the moral character of drug users, who are seen as having deviated from their good true selves.
