On the traditional view, moral distress arises only in cases where an individual believes she knows the morally right thing to do but fails to perform that action due to various constraints. We seek to motivate a broader understanding of moral distress. We begin by presenting six types of distress that fall outside the bounds of the traditional definition and explaining why they should be recognized as forms of moral distress. We then propose and defend a new and more expansive (...) definition of moral distress and examine how it can enable the development of a taxonomy of moral distress. (shrink)

What might a theory of mental imagery look like, and how might one begin formulating such a theory? These are the central questions addressed in the present paper. The first section outlines the general research direction taken here and provides an overview of the empirical foundations of our theory of image representation and processing. Four issues are considered in succession, and the relevant results of experiments are presented and discussed. The second section begins with a discussion of the proper form (...) for a cognitive theory, and the distinction between a theory and a model is developed. Following this, the present theory and computer simulation model are introduced. This theory specifies the nature of the internal representations (data structures) and the processes that operate on them when one generates, inspects, or transforms mental images. In the third, concluding, section we consider three very different kinds of objections to the present research program, one hinging on the possibility of experimental artifacts in the data, and the others turning on metatheoretical commitments about the form of a cognitive theory. Finally, we discuss how one ought best to evaluate theories and models of the sort developed here. (shrink)

The peculiar features of the climate change problem pose substantial obstacles to our ability to make the hard choices necessary to address it. Climate change involves the convergence of a set of global, intergenerational and theoretical problems. This convergence justifies calling it a 'perfect moral storm'. One consequence of this storm is that, even if the other difficult ethical questions surrounding climate change could be answered, we might still find it difficult to act. For the storm makes us extremely vulnerable (...) to moral corruption. (shrink)

This paper describes an operational computer simulation of visual mental imagery in humans. The structure of the simulation was motivated by results of experiments on how people represent information in, and access information from, visual images. The simulation includes a “surface representation,” which is spatial and quasi‐pictorial, and an underlying “deep representation,” which contains “perceptual” information encoding appearance plus “propositional” information describing facts about an object. The simulation embodies a theory of how surface images are generated from deep representations, and (...) how surface images are processed when one accesses information embedded in them. The simulation also offers an account of various sorts of imagery transformations. (shrink)

Climate change is a global problem that is predominantly an intergenerational conflict, and which takes place in a setting where our ethical impulses are weak. This "perfect moral storm" poses a profound challenge to humanity. This book explains how the "perfect storm" metaphor makes sense of our current malaise, and why a better ethics can help see our way out.

ABSTRACT In Debating Climate Ethics, David Weisbach and I offer contrasting views of the importance of ethics and justice for climate policy. I argue that ethics is central. Weisbach advocates for climate policy based purely on narrow forms of self-interest. For this symposium, I summarize the major themes, and extend my basic argument. I claim that ethics gets the problem right, whereas dismissing ethics risks getting the problem dangerously wrong, and perpetuating profound injustices. One consequence is that we should reject (...) the alleged “feasibility constraint” of short-term, economic self-interest. (shrink)

Disability and enhancement are often treated as opposing concepts. To become disabled in some respect is to move away from those who are enhanced in that same respect; to become enhanced is to move away from the corresponding state of disability. This chapter examines how best to understand the concepts of disability and enhancement in this symmetrical way. After considering various candidates, two types of accounts are identified as the most promising: welfarist accounts and typical-functioning accounts. The authors ultimately defend (...) a complex typical-functioning account as the best way to achieve a symmetrical understanding of disability and enhancement. (shrink)

A critical study of two recent books in climate ethics by Dale Jamieson (Reason in a Dark Time, Oxford 2014), and Darrel Moellendorf (The Moral and Political Challenges of Climate Change, Cambridge 2014).

Fisher’s 1918 paper accomplished two distinct goals: unifying discrete Mendelian genetics with continuous biometric phenotypes and quantifying the variance components of variation in complex human characteristics. The former contributed to the foundation of modern quantitative genetics; the latter was adopted by social scientists interested in the pursuit of Galtonian nature-nurture questions about the biological and social origins of human behavior, especially human intelligence. This historical divergence has produced competing notions of the estimation of variance ratios referred to as heritability. Jay (...) Lush showed that they could be applied to selective breeding on the farm, while the early twin geneticists used them as a descriptive statistic to describe the degree of genetic determination in complex human traits. Here we trace the early history of the heritability coefficient now used by social scientists. (shrink)

It is commonly thought that disability is a harm or “bad difference” because having a disability restricts valuable options in life. In his recent essay “Disability, Options and Well-Being,” Thomas Crawley offers a novel defense of this style of reasoning and argues that we and like-minded critics of this brand of argument are guilty of an inconsistency. Our aim in this article is to explain why our view avoids inconsistency, to challenge Crawley's positive defense of the Options Argument, and to (...) suggest that this general line of reasoning employs a double standard.

Climate change and other global environmental problems constitute a significant challenge to contemporary political philosophy, especially with respect to complacency. This paper assesses Rawls? theory, and argues for three conclusions. First, Rawls does not already solve such problems, and simple extensions of his theory are unlikely to do so. This is so despite the rich structure of Rawls? philosophy, and the appeal of some of its parts. Second, the most promising areas for extension ? the circumstances of justice, the duty (...) to maintain and promote just institutions, and his vision of social development ? are those that have not yet been explored. Third, unfortunately, Rawls? views on these topics are both seriously underdeveloped, and largely stipulative. Hence, in trying to meet climate change, Rawlsians are more likely to add new theories to Rawls, and perhaps even to transform his original account, than to generate an approach ?from the inside out?

Very few moral philosophers have written on climate change.1 This is puzzling, for several reasons. First, many politicians and policy makers claim that climate change is not only the most serious environmental problem currently facing the world, but also one of the most important international problems per se.2 Second, many of those working in other disciplines describe climate change as fundamentally an ethical issue.3.

This collection gathers a set of central papers from the emerging area of ethics and climate change.

It is widely assumed that disability is typically a bad thing for those who are disabled. Our purpose in this essay is to critique this view and defend a more nuanced picture of the relationship between disability and well-being. We first examine four interpretations of the above view and argue that it is false on each interpretation. We then ask whether disability is thereby a neutral trait. Our view is that most disabilities are neutral in one sense, though we cannot (...) make simple generalizations about disability's relationship to well-being in other important senses. After defending this view, we discuss its practical implications for selective abortion for disability, nondisabled people's interactions with disabled people, and the use of QALYs in health policy.

The concept of representation has become almost inextricably bound to the concept of symbol systems. the concepts is nowhere more prevalent than in descriptions of "internal representations." These representations are thought to occur in an internal symbol system that allows the brain to store and use information. In this paper we explore a different approach to understanding psychological processes, one that retains a commitment to representations and computations but that is not based on the idea that information must be stored (...) and manipulated in symbol systems. In particular, we suggest that the notion of a symbol system as currently understood construes psychological processes in terms of a specific type of computational system, in which a control function "reads," "interprets," and manipulates discrete entities called "symbols." We argue that other types of computational systems may provide a more appropriate characterization of psychological processes. One implication of our argument is the need to consider the constraints placed on computational theories in psychology by the nature of the computing device itself, the human brain. Perhaps surprisingly, this implication leads us to the conclusion that a "functionalist" conception of psychological processes (discussed below) does not entail that physiology is irrelevant to psychology, as has been maintained by prominent adherents of the symbol-systems approach.

“[T]he Precautionary Principle still has neither a commonly accepted definition nor a set of criteria to guide its implementation. “There is”, Freestone … cogently observes, “a certain paradox in the widespread and rapid adoption of the Precautionary Principle”: While it is applauded as a “good thing”, no one is quite sure about what it really means or how it might be..

The philosophical literature on well-being and the good life contains very little explicit discussion of what makes for a better or worse death. The purpose of this essay is to highlight some commonly held views about the good death and investigate whether these views are recognized by the leading theories of well-being. While the most widely discussed theories do have implications about what constitutes a good death, they seem unable to fully accommodate these popular good death views. I offer two (...) partial explanations for why these views have been neglected in discussions of well-being and make two corresponding recommendations for future work in the philosophy of well-being.

The distant future poses a severe moral problem, the nature and extent of which has not yet been adequately appreciated. This paper offers a brief, initial account of this problem and its main features. It also argues (1) that the problem is the main concern of distinctively intergenerational ethics, and (2) that it occurs both in a pure, long-term form manifest across human history and global populations, and also in degenerate forms which apply to shorter time periods and to social (...) institutions.

Recently, I have been arguing for a global constitutional convention focused on protecting future generations. This deliberative body would be akin to the American constitutional convention of 1787, which gave rise to the present structure of government in the United States. It would confront the “governance gap” that currently exists surrounding concern for future generations. In particular, contemporary institutions tend to crowd out intergenerational concern, and thereby facilitate a “tyranny of the contemporary.” They not only fail to address a basic (...) standing threat to humanity and other species, but help that threat become manifest. Climate change is a prime example. In this paper, I sketch out a natural argumentative path toward the global constitutional convention and argue that is difficult to resist. I also insist that we should be evenhanded in the way we treat the proposal. Those who put their faith in alternatives must also confront standard complaints about naivety, urgency, threats to democratic values, and the like. Moreover, the global constitutional convention has the advantage of addressing the problem we face head on. (shrink)

It is widely recognized that lives and activities can be meaningful or meaningless, but few have appreciated that they can also be anti-meaningful. Anti-meaning is the polar opposite of meaning. Our purpose in this essay is to examine the nature and importance of this new and unfamiliar topic. In the first part, we sketch four theories of anti-meaning that correspond to leading theories of meaning. In the second part, we argue that anti-meaning has significance not only for our attempts to (...) theorize about meaning in life, but also for our ability to lead meaningful lives in the modern world.

In two celebrated and widely-anthologized articles, as well as several books, the biologist Garrett Hardin claims (a) that the world population problem has a certain structure – it is a tragedy of the commons - and, (b) that, given this structure, the only tenable solutions involve either coercion or immense human suffering. In this paper, I shall argue for two claims. First, Hardin’s arguments are deeply flawed. The population problem as he conceives it does not have the structure of a (...) commons; and even if it did, this would not necessitate the extreme responses he canvasses. Second, nevertheless, much of Hardin’s pessimism is justified. Some environmental problems associated with population do have tragic structures, though these are of a different form than Hardin envisions. For example, the problem of global climate change has an intergenerational aspect that makes it importantly worse than Hardin’s commons, and for this reason (as opposed to Hardin’s) extreme responses may be needed to avert environmental catastrophe.

Recently in the pages of The Classical Quarterly Mathias Hanses convincingly demonstrated the existence of a fourth occurrence of the programmatic adjective λεπτός in Aratus, Phaen. 783–7. This new example occurs in the form of a diagonal acrostic alongside the known ‘gamma-acrostic’ and the occurrence of the same form of the adjective in line 784. Jerzy Danielewicz has now proposed yet a fifth instance of λεπτή in the form of an acronym spread over two lines and meant to be read (...) anticlockwise. (shrink)

I critically examine the semantic view of theories to reveal the following results. First, models in science are not the same as models in mathematics, as holders of the semantic view claim. Second, when several examples of the semantic approach are examined in detail no common thread is found between them, except their close attention to the details of model building in each particular science. These results lead me to propose a deflationary semantic view, which is simply that model construction (...) is an important component of theorizing in science. This deflationary view is consistent with a naturalized approach to the philosophy of science. (shrink)

The so-called Disability Paradox arises from the apparent tension between the popular view that disability leads to low well-being and the relatively high life-satisfaction reports of disabled people. Our aim in this essay is to make some progress toward dissolving this alleged paradox by exploring the relationship between disability and various “goods of life”—that is, components of a life that typically make a person’s life go better for her. We focus on four widely recognized goods of life (happiness, rewarding relationships, (...) knowledge, achievement) and four common types of disability (sensory, mobility, intellectual, and social) and systematically examine the extent to which the four disability types are in principle compatible with obtaining the four goods of life. Our findings suggest that that there is a high degree of compatibility. This undermines the widespread view that disabilities, by their very nature, substantially limit a person’s ability to access the goods of life, and it provides some guidance on how to dissolve the Disability Paradox.

This paper argues that extortion is a clear threat in intergenerational relations, and that the threat is manifest in some existing proposals in climate policy and latent in some background tendencies in mainstream moral and political philosophy. The paper also claims that although some central aspects of the concern about extortion might be pursued in terms of the entitlements of future generations, this approach is likely to be incomplete. In particular, intergenerational extortion raises issues about the appropriate limits to the (...) sway of central values such as welfare and distributive justice. We should be wary of ways in which such values invite us to buy off, or perhaps to join, an intergenerational climate Mafia. (shrink)

Traditional concern for the gradual, incremental effects of climate change remains; but now greater attention is being paid to the possibility of breaching major thresholds in the climate system with catastrophic consequences. It might be thought that the potential for abrupt climate change (a) undermines the usual (economic, psychological, and intergenerational) analyses of the climate change problem, and (b) in doing so helps us to act. Against this, I argue both that much of the psychological and intergenerational analyses remains in (...) place, and that abrupt climate change may make action more difficult, perhaps even setting off an intergenerational arms race.

Lucas Matthews and I substantially revised my SEP entry on Heritability. This version includes discussion of the missing heritability problem and other issues that arise from the use of Genome Wide Association Studies by Behavioral Geneticists.

ABSTRACTThis article offers a constructive critique of the Oxford Principles for the governance of geoengineering and proposes an alternative set of principles, the Tollgate Principles, based on that critique. Our main concern is that, despite their many merits, the Oxford Principles remain largely instrumental and dominated by procedural considerations; therefore, they fail to lay the groundwork sufficiently for the more substantive ethical debate that is needed. The article aims to address this gap by making explicit many of the important ethical (...) questions lurking in the background, especially around values such as justice, respect and legitimacy.

In this paper I examine various ways in whichphilosophers have made connections between truth andnatural selection. I introduce several versions ofthe view that mechanisms of true belief generationarise as a result of natural selection and argue thatthey fail to establish a connection between truth andnatural selection. I then turn to scientific truthsand argue that evolutionary accounts of the origin ofscientific truth generation mechanisms also fail. Iintroduce David Hull's selectionist model ofscientific development and argue that his account ofscientific success does not (...) rely on connecting truthand natural selection. I argue that Hull's model,which severs the connection between truth andselection, can account for some aspects of scientificchange, but it still leaves us plenty of questionsabout what aspects of our individual cognitive make-upcontribute to scientific change and how they do so. I introduce an evolutionary approach to scientificcognition that shows how some of these questions canbe answered without making an explanatory appeal toselection for true belief generating mechanisms.

ABSTRACT:Many of humanity's most serious problems are global, intergenerational, and ecological, yet current institutions are poorly placed to confront such problems. In part, this institutional challenge reflects difficulties with our basic concepts and theories. Bioethics is a central area where such questions arise. Although some have argued for an environmentalized bioethics since its inception, biomedicine has thus far failed to embrace the challenge, and some accuse most bioethicists of being "asleep at the wheel" (Schenck and Churchill 2021). This paper discusses (...) the basic ethical challenge, offers the "perfect moral storm" analysis, and explores one promising new concept for bioethics, planetary health, in light of that analysis. Drawing on the foundational report of the Rockefeller Foundation–Lancet Commission (Whitmee et al. 2015) and using climate change as the example, the author argues that planetary health has significant strengths but also some weaknesses, and that identifying both is helpful in charting a path forward for environmentalized bioethics.

It seems better to have a life that begins poorly and ends well than a life that begins well and ends poorly. One possible explanation is that the very shape of a life can be good or bad for us. If so, this raises a tough question: when can the shape of our lives be good or bad for us? In this essay, I present and critique an argument that the shape of a life is a non-synchronic prudential value—that is, (...) something that can be good or bad for us in a way that is not good or bad for us at any particular time. After distinguishing two interpretations of ‘the shape of a life’, I argue that the first type of shape can be good or bad for us at particular moments while the other cannot be good or bad for us at all. This suggests that the shape of a life gives us no reason to posit non-synchronic prudential values. (shrink)

Contract theories – such as contractarianism and contractualism - seek to justify (and sometimes to explain) moral and political ideals and principles through the notion of “mutually agreeable reciprocity or cooperation between equals” (Darwall 2002). This chapter argues that such theories face fundamental difficulties in the intergenerational setting. Most prominently, the standard understanding of cooperation appears not to apply, and the intergenerational setting brings on a more severe collective action problem than the traditional prisoner’s dilemma. Mainstream contract theorists (such as (...) Gauthier and Rawls) have tried to overcome such difficulties by postulating some kind of chain of connection between generations. However, the chapter maintains that thus far such attempts have proven inadequate. Given this, it seems either that mainstream contract theory needs to be rethought, or that a new, specifically intergenerational, contract theory is needed. (shrink)
