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)

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.

This was one of SCSS President Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns in The Wanderer in 2021. In it, he says that in spite of the left’s irresponsible claims about “systemic racism” in America, motivated by their ideological objectives, they pay little attention to the real problems in the Black community such as illegitimacy, family breakdown, and fatherlessness.

SCSS President Stephen M. Krason wrote this letter in response to a review about a book he edited and contributed to in the SCSS’s Catholic Social Thought Book Series, The Crisis of Religious Liberty: Reflections from Law, History, and Catholic Social Thought. The review, which appeared in The Journal of Church and State, was mostly favorable to the book but made erroneous assertions and a false and unmerited conclusion about the sources Krason used in his Afterword in the book. (...) Krason also sent the letter to the editor of the Journal, but they apparently don’t run letters and did not make an exception with this one. Krason also sent a copy of this letter to the other contributors to the book and includes it here out of a sense of the need to have a public record of a response to a published book review that, of course, was publicly disseminated.

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.

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 liberal democracies that were British colonies, law constructs the linkages and distinctions between individual and political bodies. Legality re-iterates the form of an ancient construct called the King’s Two Bodies. The legal construction of these bodies ensures that their borders are continuously and perpetually contested and transgressed, and different modalities of power have arisen to take advantage of them. Additionally, in times of mass insecurity or crisis, we might believe that we need to fix our (personal or political) borders (...) and construct them in more solid ways. However, because other modalities of power take advantage of these borders, even if legal reconstruction can momentarily assuage concerns, it is argued here that legal processes construct borders around individual and political bodies to ensure the (re)production of those contests and crises.

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 appear monthly in Crisis and The Wanderer. In it, he summarizes his conclusions about the conformity of current American conservatism with Catholic social teaching—as put forth in the papal social encyclicals—on the subject of economics and social welfare policy from his 2017 book, Catholicism and American Political Ideologies. His analysis is based on the 2012 Republican party platform, which was held to be (...) a particularly conservative document—and thus a good measure of current conservative thinking on public policy questions. He concludes that American conservative thinking about economics and social welfare policy conforms reasonably well—certainly not perfectly—with Catholic social teaching. (shrink)

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.

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.

This article, which inaugurated SCSS president Stephen M. Krason’s monthly online column, “Neither Left Nor Right but Catholic”, takes note of an important address given by Archbishop Charles Chaput in Europe in which he foresees increasing repression by an arch-secularist political and cultural elite against Catholics and the Church when they try to bring the Church’s message to society. This represents a deeply disturbing narrowing of the meaning of religious liberty to mere freedom of worship.

This article is one of SCSS President Stephen M. Krason’s “Neither Left nor Right, but Catholic” online columns. It briefly addresses, in light of Catholic social teaching, the immigration question that has been a major public issue in the U.S.

The past two decades have seen an outpouring of work in legal theory that is self-consciously critical of aspects of American law and the institutions of the liberal state. In this lively volume, eminent scholars in philosophy, law, and political science respond to this recent scholarship by exploring what constitutes a "radical" critique of the law, examining such theories as critical legal studies, feminist theory and theories of "difference," and critical race theory. The authors consider whether the critiques advanced in (...) recent legal theory can truly be called radical and what form a radical critique of American law should take. Writing at the cutting edge of the critique of critical legal theory, they offer insights first on critical legal scholarship, then on feminist political and legal theory. A third group of contributions questions the radicalness of these approaches in light of their failure to challenge fundamental aspects of liberalism, while a final section focuses on current issues of legal reform through critical views on criminal punishment, including observations on rape and hate speech. Each major essay describes the underlying principles in the development of a radical legal theory and addresses unresolved questions relating to it, while accompanying commentaries present conflicting views. The resulting dialogue explores wide-ranging issues like equity, value relativism, adversarial and empathic legal advocacy, communitarianism and the social contract, impartiality and contingency, "natural" law, and corrective justice. A common thread for many of the articles is a focus on the social dimension of society and law, which finds the individualism of prevailing liberal theories too limiting. Radical Critiques of the Law is particularly unique in presenting critical and feminist approaches in one volume-along with skeptical commentary about just how radical some critiques really are. Proposing alternative critiques that embody considerably greater promise of being truly radical, it offers provocative reading for both philosophers and legal scholars by showing that many claims to radicalism are highly problematic at best.

The study of civilizations is largely motivated by a single question—what drives and defines a culture or civilization? In an effort to locate a civilization—or, in the case of this chapter, three civilizations—historically, perhaps the best way is to call this drive and defining quality the cultural “sovereign.” Historically, in almost every case, this sovereign takes on a spiritual and religious form in the earliest and most vitalized period of any civilization’s lifespan. Conceptualizing civilizations in two phases, this chapter will (...) seek to show that, as a rule, at some point this spiritual sovereign is usurped and replaced by a human and corrupted sovereign. This transition precipitates the decay of Civilization, first explored by Oswald Spengler, examined here with a focus on the point at which the original and eternal sovereign ceases to be the arbiter of moral and cultural questions, and the State takes over this sovereignty. To understand “sovereignty,” the chapter appeals to Schmitt; the sovereign is one who has the power “to decide the exception.” In this way, the ethos of a culture begins as something in which no exceptions can be made by a human being—the point at which the eternal is sovereign. As civilization declines, however, one witnesses human beings making exceptions,as morality ceases to be binding, social propriety becomes a luxury rather than a necessity, and religion becomes a fixture rather than the core of society. This state of collapse is highlighted in three separate civilizations—the Civic (i.e. Graeco-Roman), the Pharaonic (i.e. Egyptian), and the Ecclesiastic (i.e. Western). The viability of any project aimed at “revival” or “regeneration” is also examined and, the author hopes, soundly denied. (shrink)

Priorities in Medical Research was published in 1988 by a select committee of the House of Lords. The report ushered in an era of NHS research and development that lasted from 2001 to 2006. The inquiry's origins lay in concerns about academic medicine in the United Kingdom, yet PMR gave relatively little attention to this subject. Instead the report focused critically on the disconnect between the Department of Health and the NHS in R & D. This, the committee argued, had (...) led to the neglect of research into health services and public health. To sidestep the report's unwelcome proposal for a National Health Research Agency, the department eventually grafted R & D management onto structures created as part of wider NHS reforms. The Medical Research Council successfully pursued a strategy of keeping the committee's attention away from sensitive aspects of its own programme. The final focus of PMR was shaped by an alignment between committee members with an industrial view of research and champions of health services research. The actions of the various actors involved are interpreted using elite models of the state, and the applicability of these models is critically examined. (shrink)

In this paper I briefly introduce work on ancient-DNA and give some examples of the impact this work has had on responses to questions in archaeology. Next, I spell out David Reich’s reasons for his optimism about the contribution aDNA research makes to archaeology. I then use Robert Chapman and Alison Wylie’s framework to offer an alternative to Reich’s view of relations between aDNA research and archaeology. Finally, I develop Steven Mithen’s point about the different questions archaeologists and geneticists ask, (...) arguing that different disciplinary perspectives color researchers’ perceptions of “the most important questions” or the “central topics” in a field. I conclude that evidence from aDNA research cannot solve archaeological disputes without closer, mutually respectful collaboration between aDNA researchers and archaeologists. Ancient DNA data, like radiocarbon data, is not a silver bullet for problems in archaeology. (shrink)

What is it for something to be good for you? It is for that thing to contribute to the appeal of being in your position or, more informally, “in your shoes.” To be in one’s position or shoes in the broadest possible sense is to have that person’s life. Accordingly, something is good or bad for a person in the broadest possible sense if and only if it contributes to or detracts from the appeal of having her life. What, then, (...) is a prudentially good life, or a life that goes well for the one living it? It is an appealing life. More precisely, it is a life such that having it is worthy of appeal, in and of itself. This dissertation is a defense and exploration of this way of understanding prudential value. I call it the "appealing life analysis." In Chapter I, I argue that this analysis fits well with our ways of talking about prudential value; preserves the relationship between prudential value and the attitudes of concern, love, pity, and envy; yields promising analyses of the concepts of well-being, luck, selfishness, self-sacrifice, and paternalism; and succeeds where three rival analyses fail. I also examine how this analysis bears on the relationship between prudence and morality and the debate between subjectivists and objectivists about prudential value. Chapter II draws upon the appealing life analysis to interpret a long-standing puzzle about prudential value and time. I highlight various ways in which this interpretation is informative and moves us closer to a solution to the puzzle. Chapter III provides a preliminary investigation and defense of an ethical theory that I call "prudentialism," which prescribes maximizing the appeal of having one’s own life. On certain conceptions of the appealing life, this theory has the virtue of avoiding the charge of being either too morally demanding or not morally demanding enough. I examine the structure of this theory, sketch a partial, substantive account of the appealing life, and discuss how the prudentialist can respond to various objections. (shrink)

A comprehensive, in-depth study of Roe v. Wade and Doe v. Bolton, the 1973 U.S. Supreme Court decisions which legalized abortion. The author closely analyzes the opinions, and contends that the Court made significant errors in its understanding of the many aspects surrounding abortion.

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.

Variability of aggression: human aggressive behavior varies on a number of dimensions. We argue that this variability is best understood through an interdisciplinary evolutionary approach.

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)

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«.
