The health co-benefits of CO2 mitigation can provide a strong incentive for climate policy through reductions in air pollutant emissions that occur when targeting shared sources. However, reducing air pollutant emissions may also have an important co-harm, as the aerosols they form produce net cooling overall. Nevertheless, aerosol impacts have not been fully incorporated into cost-benefit modeling that estimates how much the world should optimally mitigate. Here we find that when both co-benefits and co-harms are taken fully into account, optimal (...) climate policy results in immediate net benefits globally, overturning previous findings from cost-benefit models that omit these effects. The global health benefits from climate policy could reach trillions of dollars annually, but will importantly depend on the air quality policies that nations adopt independently of climate change. Depending on how society values better health, economically optimal levels of mitigation may be consistent with a target of 2 °C or lower. (shrink)

In ”Epistemology and Ethics,” Noah Lemos suggests that moral epistemology is mainly concerned with “whether and how we can have knowledge or justified belief” about moral issues. After addressing skeptical arguments, he considers how the moral epistemologist and moral philosopher should begin their account of moral knowledge. Lemos favors a particularist approach whereby we begin with instances of moral knowledge and use these to formulate and evaluate criteria for moral knowledge. After relating his approach to concerns about the nature (...) of the epistemic justification of moral beliefs as dealt with by foundationalists and coherentists, Lemos responds to arguments against particularist approaches in moral epistemology. Specifically, he addresses the claim that our moral beliefs must receive their justification from an independent moral criterion developed from nonmoral beliefs. (shrink)

In this essay, I argue that, all else being equal, theism is more probable than naturalism on the assumption that human beings are able to arrive at a body of moral knowledge that is largely accurate and complete. I put forth this thesis on grounds that, if naturalism is true, the explanation of the content of our moral intuitions terminates either in biological-evolutionary processes or in social conventions adopted for pragmatic reasons; that, if this is so, our moral intuitions were (...) selected for their utility, not their truth; and that, if our moral intuitions were so selected, they are probably false. I defend the argument against three objections: first, that the argument amounts to a generic skeptical challenge; second, that ethical naturalism explains how our moral intuitions could have been selected for their truth; and third, that there is a pre-established harmony between the utility of moral beliefs and their truth-values.

Is language understanding a special case of social cognition? To help evaluate this view, we can formalize it as the rational speech-act theory: Listeners assume that speakers choose their utterances approximately optimally, and listeners interpret an utterance by using Bayesian inference to “invert” this model of the speaker. We apply this framework to model scalar implicature (“some” implies “not all,” and “N” implies “not more than N”). This model predicts an interaction between the speaker's knowledge state and the listener's interpretation. (...) We test these predictions in two experiments and find good fit between model predictions and human judgments. (shrink)

We show that the theory of the partial order of computably enumerable equivalence relations (ceers) under computable reduction is 1-equivalent to true arithmetic. We show the same result for the structure comprised of the dark ceers and the structure comprised of the light ceers. We also show the same for the structure of L-degrees in the dark, light, or complete structure. In each case, we show that there is an interpretable copy of (N, +, \times) .

This essay bridges together social network and institutional perspectives to examine how women on boards, by breaking up directors’ homophilous networks, contribute to board effectiveness. It proposes that through real and symbolic representations, women enhance perceptions of the board’s instrumental, relational, and moral legitimacy, leading to increased perceptions of the board’s trustworthiness which in turn fosters shareholders’ trust in the firm. Envisioning the gender diversification of boards as an event of institutional change, this article considers the critical role of shareholder (...) activists and legislative support from the SEC in the deinstitutionalization of old boys’ networks and the reinstitutionalization of gender diverse boards. This work is substantiated with evidence obtained through 34 semi-structured interviews, archival and documentary evidence. (shrink)

Abstract: In this essay, I outline and defend a version of the aesthetic argument for the existence of God, according to which theism explains our capacity for subjective aesthetic experience better than its major competitor, naturalism. I argue that naturalism fails to adequately explain the nature and range of our aesthetic experiences, since these are amenable neither to standard Darwinian explanation nor to explanation in terms of more complex sociobiological mechanisms such as sexual selection or between-group selection. I concede that (...) aesthetic experience may be an evolutionary spandrel but argue that the conjunction of this thesis with naturalism is highly improbable given the prevalence of beauty in the natural world. Theism, on the other hand, furnishes a robust personal explanation of aesthetic experience, since on theism God has both good reasons to bring such experiences about and the power to do so. I address an objection to the theistic explanation from broadly negative aesthetic experiences, arguing that God plausibly has many reasons to allow these. I contend that this formulation of the argument is superior to other extant versions, since it does not depend on controversial probability judgments, dubious analogies between natural phenomena and human artefacts, or objectivism about aesthetic values.

I argue for the viability of one neglected way of developing supervenience-based objections to metaethical non-naturalism. This way goes through a principle known as ‘Hume’s Dictum’, according to which there are no necessary connections between distinct existences. I challenge several objections to the Hume’s Dictum-based argument. In the course of doing so, I formulate and motivate modest and precise versions of Hume’s Dictum, illustrate how arguments employing these principles might proceed, and argue that the Hume’s Dictum argument enjoys some advantages (...) relative to other supervenience-based objections to non-naturalism.

This paper explores the truism that people think about what they say. It proposes that, to satisfy their own goals, people often plan their speech acts to affect their listeners' beliefs, goals, and emotional states. Such language use can be modelled by viewing speech acts as operators in a planning system, thus allowing both physical and speech acts to be integrated into plans. Methodological issues of how speech acts should be defined in a planbased theory are illustrated by defining operators (...) for requesting and informing. Plans containing those operators are presented and comparisons are drawn with Searle's formulation. The operators are shown to be inadequate since they cannot be composed to form questions (requests to inform) and multiparty requests (requests to request). By refining the operator definitions and by identifying some of the side effects of requesting, compositional adequacy is achieved.The solution leads to a metatheoretical principle for modelling speech acts as planning operators.

I examine issues in the philosophy of religion at the intersection of what possibilities there are and what a God, as classically conceived in the theistic philosophical tradition, would be able to do. The discussion is centered around arguing for an incompatibility between theism and two principles about possibility and ability, and exploring what theists should say about these incompatibilities. -/- I argue that theism entails that certain kinds and amounts of evil are impossible. This puts theism in conflict with (...) popular principles of modal recombination. However, theists have plausible explanations for the violations of recombination that they posit, and can suitably amend these principles without giving up their usefulness in accounting for what possibilities there are. -/- I also argue that despite the impossibility of these evils, God is able to bring these evils about. This puts theism in conflict with the principle that no one is able to do the impossible. However, theists can give a plausible account of why God is unique in being able to do the impossible, and have distinctive resources to address the arguments in favor of the idea that no one is able to do the impossible. And by denying this principle, theists are able to resolve several otherwise difficult puzzles, including reconciling conflicts between the divine attributes. (shrink)

In this essay, I reply to an influential objection to evolutionary debunking arguments against moral realism. According to this objection, our capacity for autonomous rational reflection allows us to grasp moral truths independently of distorting evolutionary influences, so those influences do not prevent us from having moral knowledge. I argue that rational moral reflection is not, in fact, autonomous from evolutionary influences, since it depends on our evolved, pre-reflective grasp of moral properties. I then consider and reject the suggestion that (...) realists can supply an autonomous foundation for rational moral reflection or do without any such foundation. Next, I address the allegation that my arguments have skeptical implications for rational reflection in non-moral domains. Finally, I conclude with a gesture toward a more promising route for realists who oppose debunking arguments. (shrink)

Metaphors used to describe new technologies mediate public understanding of the innovations. Analyzing the linguistic, rhetorical, and affective aspects of these metaphors opens the range of issues available for bioethical scrutiny and increases public accountability. This article shows how such a multidisciplinary approach can be useful by looking at a set of texts about one issue, the use of a newly developed technique for genetic modification, CRISPRcas9.

This book addresses some basic questions about intrinsic value: What is it? What has it? What justifies our beliefs about it? In the first six chapters the author defends the existence of a plurality of intrinsic goods, the thesis of organic unities, the view that some goods are 'higher' than others, and the view that intrinsic value can be explicated in terms of 'fitting' emotional attitudes. The final three chapters explore the justification of our beliefs about intrinsic value, including coherence (...) theories and the idea that some value beliefs are warranted on the basis of emotional experience. Professor Lemos defends the view that some value beliefs enjoy 'modest' a priori justification. The book is intended primarily for professional philosophers and their graduate students working in ethics, value theory and epistemology. (shrink)

There is a very plausible principle linking abilities and possibilities: If S is able to Φ, then it is metaphysically possible that S Φ’s. Jack Spencer recently proposed a class of counterexamples to this principle involving the ability to know certain propositions. I renew an argument against these counterexamples based on the unknowability of Fitch propositions. In doing so, I provide a new argument for the unknowability of Fitch propositions and show that Spencer’s counterexamples are in tension with a principle (...) weaker than the one linking abilities and possibilities.

In this essay, I address an objection to inference to the best explanation due to Bas C. van Fraassen, according to which explanatory virtues cannot confirm a theory, since they make the theory more informative and thus less likely to be true given the probability axioms. I try to show that van Fraassen’s argument, once made precise, is deductively invalid, and that even an ampliative version of the argument (i) implies, absurdly, that no theory is confirmed by its fit with (...) empirical data; (ii) fails to account for confirmatory closure under deduction; and (iii) falsely presupposes that a theory and its sub-theories can be competing explanations.

Despite its increasing popularity across management disciplines, stakeholder theory holds an important shortcoming in terms of its guidance for understanding the heterogeneity of stakeholder interests, claims, and behavior toward firms. Specifically, scholars note the inadequacy of generic categories of stakeholders in providing a realistic portrait of the groups and individuals that interact with the firm, opening the theory to much criticism for a ‘simplistic’ and ‘meaningless’ stakeholder concept. In face of this challenge, recent research is pointing to social identity as (...) a mechanism to refine our understanding of stakeholders as names-and-faces, however we argue that despite the advancements offered by the social identity approach, it too presents limitations in its ability to guide managers in prioritizing stakeholder claims. Building on these nascent efforts to offer much needed nuance to a theory of stakeholder identification and prioritization, this paper draws from new advances in the management literature and offers status as an attribute that helps explain and predict how managers accord attention to their various constituents. We set forth five propositions connecting stakeholder status to the attention stakeholders receive from managers. We argue that status is a superior attribute of stakeholder identification and prioritization because it accounts for groups and individuals’ uniqueness within broad categories of stakeholders in a dynamic way, reconciles the dual nature of stakeholders as holding simultaneously a social and an economic identity in their claim toward the firm, and provides a plausible explanation of, and intuitive guidance to, how managers accord attention to their firm’s stakeholders. Implications and future directions for research complete this article. (shrink)

Brock and Glasgow recently introduced a new definition of paradox and argue that this conception of paradox itself leads to paradox, the so-called Paradox Paradox. I show that they beg the questions during the course of their argument, but, more importantly, do so in a philosophically interesting way: it reveals a counterexample to the equivalence between being a logical truth and having a probability of one. This has consequences regarding norms of rationality, undermining the grounds for the Conjunction Fallacy.

This paper explores the editorial influence of Joseph Banks on the Philosophical Transactions—still, at the time of his accession to the Presidency of the Royal Society in 1778, the most prestigious scientific periodical published in English. In particular, it examines how Banks forged, and wielded, personal influence over what went into the Transactions. Nominally, at least, the periodical was under the collective control of the Society's council, with significant statutory safeguards in place to prevent editorship by a presidential clique. Yet (...) this was exactly what Banks was able to speedily create and maintain. In this essay I explore how Banks accomplished this and the pressures it produced, addressing two key questions. First, I examine the social dimension of Banks's management of the Transactions (and what contemporaries thought of it), including particularly the questions of how and to whom access to the periodical was afforded or denied by Banks and his associates; and second, I consider how Banks and the Society dealt with the emerging competitive pressure of new commercial and learned society periodicals. I outline a sphere of scientific sociability partly created by informal processes of communicating, circulating, and evaluating papers developed by Banks and his close associates, and its significance for the Transactions in its engagements with other sites, genres, and conventions of scientific publication.

In this essay, I defend a mind-body dualism, according to which human minds are immaterial substances that exercise non-redundant causal powers over bodies, against the notorious problem of psychophysical causation. I explicate and reply to three formulations of the problem: (i) the claim that, on dualism, psychophysical causation is inconsistent with physical causal closure, (ii) the claim that psychophysical causation on the dualist view is intolerably mysterious, and (iii) Jaegwon Kim’s claim that dualism fails to account for causal pairings. Ultimately, (...) I conclude that these objections fail and that dualist interactionism is no more problematic or mysterious than physical causation. (shrink)

:Academic Medical Centers offer patient care and perform research. Increasingly, AMCs advertise to the public in order to garner income that can support these dual missions. In what follows, we raise concerns about the ways that advertising blurs important distinctions between them. Such blurring is detrimental to AMC efforts to fulfill critically important ethical responsibilities pertaining both to science communication and clinical research, because marketing campaigns can employ hype that weakens research integrity and contributes to therapeutic misconception and misestimation, undermining (...) the informed consent process that is essential to the ethical conduct of research. We offer ethical analysis of common advertising practices that justify these concerns. We also suggest the need for a deliberative body convened by the Association of American Medical Colleges and others to develop a set of voluntary guidelines that AMCs can use to avoid in the future, the problems found in many current AMC advertising practices.

In his Animadversiones on Machiavelli's The Prince (1661), Hermann Conring, one of the most famous of the early modern German professors of politics, further developed the constitutional reading of Machiavelli's The Prince, following in the footsteps of Bodin and the German political theorists of the previous generation such as Arnisaeus, Contzen, and Besold. For Conring, Machiavelli's exaggerated analysis of tyranny and his heavy emphasis on popular liberty offered not so much a realist political science but a dangerous prelude to the (...) monarchomachic theory of popular sovereignty and a fatalistic concession to sin. Conring, a committed Aristotelian with Arminian sympathies, preferred a more empirical constitutional analysis (and a theory of the state) which did not favor any particular faction of the state (i.e. the people over the nobility) as the unique source of stability or instability and which explained the necessity for wickedness as the result of poor constitutional design rather than a realistic view of human nature and fate.

Guynn offers an innovative new approach to the ethical, cultural, and ideological analysis of medieval allegory. Working between poststructuralism and historical materialism, he considers both the playfulness of allegory (its openness to multiple interpretations and perspectives) and its disciplinary force (the use of rhetoric to naturalize hegemonies and suppress difference and dissent). Ultimately, he argues that both tendencies can be linked to the consolidation of power within ruling class institutions and the persecution of demonized others, notably women and sexual minorities. (...) The book examines a number of centrally canonical works, including the verse romance Eneas , Alan of Lille’s De planctu Naturae , The Romance of the Rose , and the Querelle de la Rose.
