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.

This was one of SCSS President Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appeared during 2015 in Crisismagazine.com and The Wanderer and at his blog site. It discusses the seminal year 1965, when so many of our current social, cultural, and political problems and our difficulties in the Church began to take shape. It discusses the nature of the “new direction” that became evident that year, how crucial trends took shape, and how the developments of that (...) year led to others in the short or long run.

This was one of SCSS President Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appeared during 2015 in Crisismagazine.com and The Wanderer and at his blog site. It discusses the U.S. Supreme Court’s landmark 2015 decision on same-sex “marriage,” Obergefell v. Hodges, and its likely implications for religious liberty, true marriage, and children. He says it is the latest expression of concocted rights under the Court’s “substantive-due-process” doctrine. He suggests ways to respond to the decision politically and (...) legally—by citizens, organizations, and the use of executive power by a sound president in the near future, and by the Church.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:US War-Culture, Sacrifice and Salvation by Kelly Denton-BorhaugStephen M. VantasselUS War-Culture, Sacrifice and Salvation Kelly Denton-Borhaug oakville, ct: equinox, 2011. 279 pp. $34.95In US War-Culture, Sacrifice and Salvation, Kelly Denton-Borhaug uses cultural and linguistic analysis in order to understand the place of war in American culture and discourse. She begins by noting that war culture is so deeply embedded in America’s ethos that its citizens are generally unaware (...) of the extent to which the United States has been militarized, with both weapons and ideology. With sobering detail, Denton-Borhaug documents how the military has penetrated and shaped institutions ranging from colleges to industry. She explains how militarization is exemplified in the consumer and civilian culture through video games and the rise of a surveillance state. By way of this analysis, the author makes the case that Dwight Eisenhower’s fear concerning the influence of the military-industrial complex has fully been realized in modern America.Denton-Borhaug then addresses what she considers to be the ideological fountainhead for America’s militarism: the Christian doctrine of substitutionary atonement. In short, as Christianity teaches that an innocent man had to sacrifice himself to save humanity, so also American war-culture ideology teaches that soldiers, citizens, and the country must sacrifice on the battlefield in order to achieve national or political salvation. Denton-Borhaug suggests that politicians and others draw on the notion of the necessity of sacrifice as a way to convince people to support militarized conflict and to endure the inevitable hardships that result. By analyzing US political rhetoric between 2001 and 2003, Denton-Borhaug makes a compelling case that the Bush administration used sacrificial images of victims and abusers to set up a simple black-and-white ethical paradigm to justify the war in Afghanistan and Iraq.From there Denton-Borhaug turns to feminist theological and linguistic analysis to deconstruct the language of sacrifice in political discourse. She argues that when sacrifice in war is seen as a necessity, the brunt of its effects is often borne by the weakest groups in society. The sacrifice motif also sets up a problematic model of active masculine protectors and passive women in need of protection, which leaders often exploit to convince the public to “trust them.” [End Page 201]If Denton-Borhaug simply asked Christian leaders to guard against the use of Christian theology to justify national or political war-making interests, I doubt few would object to her case. In fact, I commend her for drawing attention to these critical issues and arguing for tactics that encourage peacemaking. Unfortunately, Denton-Borhaug argues that the solution to the political use of sacrificial theology is to jettison it, or at least to marginalize its use in Christian teaching. She proposes that we replace it with a theology of work, a cure that may be even worse than the disease she diagnoses and that is, moreover, not logically required to achieve the peacemaking she promotes. In this regard Denton-Borhaug could have been more transparent about her own presuppositions. For example, she clearly leans toward nonviolence, leaving readers to wonder whether genocide, nuclear buildup, and state-sponsored terrorism are the only justifications for war (222). Moreover, I am not completely convinced that America’s use of sacrificial language is an unvarnished harm. I suspect that at least some of the United States’ use of sacrificial language stems from a desire to avoid language that glorifies war. Would America be better off if we used militaristic terms like “Death to Afghanistan” that emphasize domination, rather than the suffering associated with “sacrifice”?Despite these weaknesses, Denton-Borhaug’s book is a valuable antidote for Christians who have grown too comfortable with America’s military-industrial complex and ideological war-culture machine. We would do well to take seriously her exhortation to work to remove the roots of war in our effort to create a world of peace.Stephen M.

The author notes how American public policy typically springs from good intentions, but brings unforeseeable consequences that cause new social problems. It also increasingly seeks to address speculative, not actual or certain, harms. He gives numerous examples and argues that the effect is increasingly expansive state power and heightened intrusion into private areas of individual and family lives. He also argues that all three public policy trends grow out of modern utopian tendencies and secularism.

This was one of SCSS President Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appear monthly in Crisis and The Wanderer. It discusses the tragic case of Charlie Gard, the baby who a U.K. hospital would not discharge so his parents could take him to the U.S. for experimental treatment for a rare, normally terminal DNA disorder that might have saved his life. Krason says that the case illustrated a number of dangerous current trends in Western political (...) societies: the advancement of the euthanasia/“quality of life” mindset, the suppression of parental rights by both child protective-type agencies and courts that are overly-deferential to them, runaway judicial power generally, the increasing authoritarianism of functional experts, and the unwillingness of elected political officials and leaders to come to the aid of the citizenry by standing up to them and the unelected bureaucrats and judges who protect them and more generally to uphold the traditional legal norms and principles that they are violating.

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.

Imagine that you are given access to an AI chatbot that compellingly mimics the personality and speech of a deceased loved one. If you start having regular interactions with this “thanabot,” could this new relationship be a continuation of the relationship you had with your loved one? And could a relationship with a thanabot preserve or replicate the value of a close human relationship? To the first question, we argue that a relationship with a thanabot cannot be a true continuation (...) of your relationship with a deceased loved one, though it might support one’s continuing bonds with the dead. To the second question, we argue that, in and of themselves, relationships with thanabots cannot benefit us as much as rewarding and healthy intimate relationships with other humans, though we explain why it is difficult to make reliable comparative generalizations about the instrumental value of these relationships.

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)

We focus on a particular class of computably enumerable degrees, the array noncomputable degrees defined by Downey, Jockusch, and Stob, to answer questions related to lattice embeddings and definability in the partial ordering of c. e. degrees under Turing reducibility. We demonstrate that the latticeM5 cannot be embedded into the c. e. degrees below every array noncomputable degree, or even below every nonlow array noncomputable degree. As Downey and Shore have proved that M5 can be embedded below every nonlow2 degree, (...) our result is the best possible in terms of array noncomputable degrees and jump classes. Further, this result shows that the array noncomputable degrees are definably different from the nonlow2 degrees. We note also that there are embeddings of M5 in which all five degrees are array noncomputable, and in which the bottom degree is the computable degree 0 but the other four are array noncomputable.

Like it or not, technologists are increasingly being called upon to »save the world«, including from themselves. Today, science and engineering professionals stand on the front-lines both in generating severe risks to the future, and in the search for solutions. This chapter examines the ethical context of their predicament. It begins by outlining the central, characteristic threat to the future, the »tyranny of the contemporary«.

In 1932, as America struggled to overcome the great economic depression and Hitler was taking power in Germany, Dewey issued a challenge to teachers. Based upon what he viewed as the principle by which to judge "the processes of education, formal and informal," he urged teachers to embrace the following goal: "Education should create an interest in all persons in furthering the general good, so that they will find their own happiness realized in what they can do to improve the (...) conditions of others" (LW 7: 243).In setting this challenge to teachers, Dewey has in mind helping students develop their character in two ways. First, teachers should nurture students' sensitivity to the impact of their speech and actions .. (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)

Cook (1995) criticizes the work of Jacobs and Kosslyn (1994) on spatial relations, shape representations, and receptive fields in neural network models on the grounds that first‐order correlations between input and output unit activities can explain the results. We reply briefly to Cook's arguments here (and in Kosslyn, Chabris, Marsolek, Jacobs & Koenig, 1995) and discuss how new simulations can confirm the importance of receptive field size as a crucial variable in the encoding of categorical and coordinate spatial relations and (...) the corresponding shape representations; such simulations would testify to the computational distinction between the different types of representations.

The author argues that there are serious problems from the standpoint of Catholic social teaching in making the forcible spreading of democracy an objective of U.S. foreign policy. He argues that U.S. policy, in light of Catholic social teaching, should be prudently interventionist—but not primarily in a military sense—in promoting human rights, diffusing international tensions, and peacekeeping. Also, the author discusses such questions as shaping U.S. foreign policy in conjunction with allies and foreign aid, in light of Catholic social teaching.

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)

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)

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.

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 the past few years it has become apparent that the anterior/posterior (A/P) and dorsal/ventral (D/V) compartmant boundaries serve as the source of longrange signals that organize the A/P and D/V axes of the Drosophila wing. Recent work suggests that the vestigial gene may function as a nodal point through which the growth‐controlling activity of these two patterning systems is integrated(1).

SR proteins are essential for the splicing of messenger RNA precursors in vitro, where they also alter splice site selection in a concentration‐dependent manner. Although experiments involving overexpression or dominant mutations have confirmed that these proteins can influence RNA processing decisions in vivo, similar results with loss‐of‐function mutations have been lacking. Now, a system for genetic depletion of the chicken B cell line DT40 has revealed that the SR protein ASF/SF2 (alternative splicing factor/splicing factor 2) is essential for viability in (...) these cells(1). This study opens the way for a complete functional dissection of this protein, and other SR proteins, in vivo. (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.

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.

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)

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)
