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.

“[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..

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)

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.

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.

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)

I propose an approach to naturalized philosophy of science that takes the social nature of scientific practice seriously. I criticize several prominent naturalistic approaches for adopting "cognitive individualism", which limits the study of science to an examination of the internal psychological mechanisms of scientists. I argue that this limits the explanatory capacity of these approaches. I then propose a three-level model of the social nature of scientific practice, and use the model to defend the claim that scientific knowledge is socially (...) produced. (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 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)

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 review some theoretical exchanges and empiricalresults from recent work on human behavior and cognition in thehope of indicating some productive avenues for critical engagement.I focus particular attention on methodological debates between Evolutionary Psychologists and behavioral ecologists. I argue for a broader and more encompassing approach to the evolutionarily based study of human behavior and cognition than either of these two rivals present.

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.

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.

We argue that heritability estimates cannot be used to make informed judgments about the populations from which they are drawn. Furthermore, predicting changes in heritability from population changes is likely impossible, and of limited value. We add that the attempt to separate human environments into cultural and non-cultural components does not advance our understanding of the environmental multiplier effect.

Creating education systems that promote democratic sustainability has been the concern of political thinkers as diverse as J. S. Mill, Dewey, Benjamin Barber and Derek Bok. The classic dichotomisation of democratic theory between deliberative democrats and Schumpeterian democrats suggests that education in the service of democracy can be constructive—that is, provide a student with the skills necessary to elect her leaders without changing her nature—or reconstructive—that is, fundamentally and radically reshape the student to produce a citizen whose goals are transformed (...) to be congruent with society. Michael Oakeshott, who has written extensively both on political regimes and on the purpose of liberal education, offers a third way to assess the connection between government and education. Despite his own dismissal of civic or political education as fundamentally vocational and thus beyond the boundaries of the liberal arts, this paper provides a potentially surprising Oakeshottian defence of political education within the liberal arts with reference to the importance he places on experience as a pedagogic tool. Thus, Oakeshott's educational philosophy has a certain resonance with the recent calls to locate the relevance of liberal arts within the burgeoning development of experiential civic engagement programmes in American universities.

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.

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.

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)

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)

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).

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)

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)

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)

There is widespread agreement that ethical concerns are central to decision-making about, and governance of, geoengineering. This is especially true of the most prominent and paradigm example of climate engineering, the spraying of sulfate particles into the stratosphere in order to block incoming sunlight and so limit global warming ). Geoengineering ethics, like geoengineering science, is still in its early, exploratory days. This chapter offers an introductory overview of the emerging discussion and some of the challenges moving forward, taking SSI (...) as its key example. It identifies a range of values relevant to geoengineering, exposes some misleading early framings, argues that questions of justification and context are both important, and summarizes the Tollgate principles for geoengineering governance. One theme is that despite the initial agreement on the centrality of ethics, in practice there are profound risks that ethical considerations will be marginalized, both in the short-term as research is developed, and in the longer-run, in any deployment.

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)

In Child Abuse, Family Rights, and the Child Protective System: A Critical Analysis from Law, Ethics, and Catholic Social Teaching, Stephen M. Krason gathers essays by leading scholars and practitioners to comment through the prism of Catholic social thought, on the plight afflicting American families and the role of the child protective system. Here readers will find critical essays on the deleterious effect of the 1974 passage of the Child Abuse Prevention and Treatment Act; assessments of current American policies (...) on child abuse and neglect and the role of the CPS within the context of prevailing international human rights principles and Catholic social teaching; a survey of the enforcement of CPS policies from a legal and constitutional perspective; research data disputing the CPS principle that all parents are potential abusers and illustrating the greater prevalence of abuse and neglect in broken, “blended,” and “untraditional” families; and arguments for poverty and unemployment as the prime culprits in the mistreatment of children. Also included are the amicus curiae briefs that the Society of Catholic Social Scientists submitted in two U.S. Supreme Court cases on parental rights, the CPS, and state control over the family.

There is a link to Krason’s monthly column at the SCSS website. Since August 2012, his column also appears at Crisismagazine.com. This article considers new, serious threats to free speech in the contemporary Western world.

This was one of SCSS president and Franciscan University of Steubenville professor Stephen M. Krason’s “Neither Left Nor Right, but Catholic” columns that appeared initially in Crisismagazine.com on September 17, 2013. It points to the curious similarities between what the adherents of the Albigensian heresy —which, incidentally, helped trigger the Inquisition—believed and current cultural perspectives. The parallels between the Albigensians and the current age, especially on sexual and human life questions and male-female relations, are striking.

Wagering contingent on a previous decision, or post-decision wagering, has recently been proposed to measure conscious awareness. Whilst intuitively appealing, it remains unclear whether economic context interacts with subjective confidence and how such interactions might impact on the measurement of awareness. Here we propose a signal detection model which predicts that advantageous wagers placed on the identity of preceding stimuli are affected by loss aversion, despite stimulus visibility remaining constant. This pattern of predicted results was evident in a psychophysical task (...) where we independently manipulated perceptual and economic factors. Changes in wagering behaviour induced by changes in wager size were largely driven by changes in criterion, consistent with the model. However, for near-threshold stimuli, a reduction in wagering efficiency was also evident, consistent with an apparent but potentially illusory decrease in awareness of the stimulus. These findings challenge an assertion that post-decision wagering provides a direct index of subjective awareness. (shrink)
