One of the most difficult problems facing anyone who would discuss Professor Carl Hempel's thesis about explanation is the following: which of the many objections that have been made are actually relevant to the thesis? Professor Hempel has claimed that several of these objections are not relevant at all. In order to evaluate such replies, let me first state what I take to be the three claims which constitute Professor Hempel's thesis.His first claim is that all adequate scientific explanations possess (...) a certain property:... all scientific explanations and their everyday counterparts claim or presuppose at least implicitly the deductive or inductive subsumability of whatever is to be explained under general laws or theoretical principles.

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.

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)

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.

Today humanity faces radical global climate change, mass species extinctions, and unprecedented transformations to both terrestrial and aquatic ecosystems across the globe. Environmental ethics is an academic subfield of philosophy concerned with normative and evaluative propositions about the world of nature and, perhaps more generally, the moral fabric of relations between human beings and the world we occupy. This Handbook contains 45 newly commissioned essays written by leading experts and emerging voices and represent some of the best and most contemporary (...) thinking in environmental ethics. The chapters range over a broad variety of issues, concepts, and perspectives that are both central to and characteristic of the field, thus providing an authoritative but accessible account of the history, analysis, and prospect of ideas that are essential to contemporary environmental ethics.

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)

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)

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.

“[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..

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)

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.

When a fragmented line-drawing of an object moves relative to a background of randomly oriented lines, the previously hidden object can be segregated from the background and consequently enters awareness. In this shape-from-motion paradigm, the percept of the object briefly persists after the motion stops, demonstrating the maintenance of a bound percept in awareness. This study investigated how the manipulation of object features that are crucial to recognition influences both the binding process and the maintenance of objects in awareness. Overall, (...) we found that objects that took longer to recognize were nonetheless maintained in awareness for longer. We argue that this effect is mediated by additional elaborative processing that is required to bind these less recognizable forms, which generates stronger and more robust representations. These representations are then more easily maintained in awareness, suggesting an important role of elaborative mechanisms for conscious representations. (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.

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)

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)

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.

Here, in the middle of the well-known simile that depicts Aeneas and Turnus as bulls fighting for territory and a herd , Vergil registers the reactions of the onlookers. Commentators and lexicographers disagree about what the heifers are doing, interpreting ‘mussant’ in different ways. Servius glosses the verb as ‘dubitant’. By contrast, Heyne offers the paraphrase ‘anxii expectant’, responding to the theme of fear in the two preceding cola: cf. ‘pavidi’ and ‘metu’. Forbiger's explanatory ‘tacite expectant’ stresses rather the note (...) of silence introduced by ‘stat pecus omne metu mutum’. Lewis and Short and Georges concur with Forbiger when they translate ‘mussant’ ‘expect in silence’ and ‘stumm harren’. Other authorities, however, underscore the verb's onomatopoeic sense. Julius Caesar Scaliger, for example, observes of Vergil's usage: ‘sane verbum factitium, neque absonum a bourn voce’. Accordingly, some older commentators interpret ‘mussant’ as a restrained form of ‘mugiunt’. More recently, the OLD and TLL cite Aen. 12.718 under the definitions ‘mutter in indecision’ and ‘mussantem dubitare’. Although there is general agreement that ‘mussant’ connotes uncertainty, there still remains the problem of whether it indicates silence, faint lowing, or muttering. The purpose of this note is to call attention to an unrecognized etymological wordplay in line 718 which helps explain what the heifers are doing and why there are varying interpretations of ‘mussant’.

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).

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)

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.

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)

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.

This essay introduces and defends a new analysis of prudential value. According to this analysis, what it is for something to be good for you is for that thing to contribute to the appeal or desirability of being in your position. I argue that this proposal fits well with our ways of talking about prudential value and well-being; enables promising analyses of the related concepts of luck, selfishness, self-sacrifice, and paternalism; preserves the relationship between prudential value and the attitudes of (...) concern, love, pity, and envy; and satisfies various other desiderata. I also highlight two ways in which the analysis is informative and can lead to progress in our substantive theorizing about the good life. (shrink)

The Carnegie Council's work “is rooted in the premise that the incorporation of ethical concerns into discussions of international affairs will yield more effective policies both in the United States and abroad.” In honor of the Council's centenary, we have been asked to present our views on the ethical and policy issues posed by climate change, focusing on what people need to know that they probably do not already know, and what should be done. In that spirit, this essay argues (...) that climate change poses a profound ethical challenge, that the ongoing evasion of this challenge produces ineffective policy, and, therefore, that a fundamental paradigm shift is needed. More specifically, I maintain that the climate problem is usually misdiagnosed as a traditional tragedy of the commons, that this obscures two deeper and distinctively ethical challenges, and that we should address these challenges head on, by calling for a global constitutional convention focused on future generations.

The Royal Society's landmark report on geoengineering is predicated on a particular account of the context and rationale for intentional manipulation of the climate system, and this ethical framework probably explains many of the Society's conclusions. Critical reflection on the report's values is useful for understanding disagreements within and about geoengineering policy, and also for identifying questions for early ethical analysis. Topics discussed include the moral hazard argument, governance, the ethical status of geoengineering under different rationales, the implications of understanding (...) geoengineering as a consequence of wider moral failure, and ethical resistance to invasive interventions in environmental systems.

This contribution provides an assessment of the epistemological role of scientific models. The prevalent view that all scientific models are representations of the world is rejected. This view points to a unified way of resolving epistemic issues for scientific models. The emerging consensus in philosophy of science that models have many different epistemic roles in science is presented and defended.
