This long-awaited work by prominent Harvard psychologist Stephen Kosslyn integrates a twenty-year research program on the nature of high-level vision and mental ...

I introduce a range of examples of different causal hypotheses about human mate selection. The hypotheses I focus on come from evolutionary psychology, fluctuating asymmetry research and chemical signaling research. I argue that a major obstacle facing an integrated biology of human behavior is the lack of a causal framework that shows how multiple proximate causal mechanisms can act together to produce components of our behavior.

Biologists, climate scientists, and economists all rely on models to move their work forward. In this book, I explore the use of models in these and other fields to introduce readers to the various philosophical issues that arise in scientific modeling. I show that paying attention to models plays a crucial role in appraising scientific work. -/- After surveying a wide range of models from a number of different scientific disciplines, I demonstrate how focusing on models sheds light on many (...) perennial issues in philosophy of science and in philosophy in general. For example, reviewing the range of views on how models represent their targets introduces readers to the key issues in debates on representation, not only in science but in the arts as well. Also, standard epistemological questions are cast in new and interesting ways when we confront the question, "What makes for a good (or bad) model?". (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. 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 is an updated version of my Stanford Encyclopedia entry on Evolutionary Psychology. The 2018 version contains a new section on Human Nature as well as some new material on recent developments in Evolutionary Psychology.

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 was one of SCSS President Stephen M. Krason’s online “Neither Left nor Right, but Catholic” columns. It appeared on April 1, 2012. 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 Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appeared during 2014 in Crisismagazine.com and The Wanderer and at his blog site. He argues that, despite the criticism of President Obama’s seemingly excessive exercise of executive power to further an ideologically leftist secularist agenda, the strong and maybe unprecedented use of presidential power after him may be the most certain way to try to restore weakened American constitutional principles and traditional liberties (...) and to begin to reverse our serious cultural decay.

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)

Stephen M. Krason presented this talk at the “Stand Up for Religious Freedom” rally in Buffalo, New York on June 8, 2012. It was one of many that were held around the U.S. that day, to show opposition to the attempt by the Obama administration’s Department of Health and Human Services to mandate that religious entities provide free contraceptives and sterilization procedures in their health insurance programs.

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.

This was one of SCSS President, Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appear monthly at his blog site and in Crisismagazine.com and The Wanderer. This column tells families and others proposing the “Benedict Option”—i.e., trying to separate as much from the secular culture as possible and trying to build up small Catholic subcultures where their children can be effectively reared in the Faith and family integrity preserved—to be attentive of the threat posed by the (...) current child protective system and the need to seek to reform it.

This was one of SCSS President, Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appear monthly at his blog site and in Crisismagazine.com and The Wanderer. This column speaks about what might be called a new expression of literalism and fundamentalism, especially among liberal Catholics and some in Church leadership, to take certain Scriptural passages and Church teachings and apply them to current situations and public questions without regard to the context of the situations or full (...) attention to nuances or even to the facts present—to in a certain sense absolutize the contingent. Sometimes this is done to promote certain policy agendas and without even considering the full statement of the Church’s teaching, as it is expressed in the social encyclicals and other documents.

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)

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. He makes an assessment, in light of Catholic social teaching, of the race issue in America today. He argues that the typical commentary about it ignores obvious realities, is often driven by ideology and the opportunism of self-appointed racial spokesmen, and ignores serious, deep-seated problems in minority communities with tragic (...) consequences.

This was one of SCSS President Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appeared during 2014 in Crisismagazine.com and The Wanderer and at his blog site. It discusses how Catholic social teaching does not mandate particular public policies and must not be confused with a point of the teaching itself. It emphasizes that there can typically be many different policy approaches that can be used to make sure that moral demands are met.

In this paper I assess Gopnik and Meltzoff's developmental psychology of science as a contribution to the understanding of scientific development. I focus on two specific aspects of Gopnik and Meltzoff's approach: the relation between their views and recapitulationist views of ontogeny and phylogeny in biology, and their overall conception of cognition as a set of veridical processes. First, I discuss several issues that arise from their appeal to evolutionary biology, focusing specifically on the role of distinctions between ontogeny and (...) phylogeny when appealing to biology for theoretical support. Second, I argue that to presuppose that cognition is veridical or "truth-tropic" can compromise attempts to understand scientific cognition both throughout history and in the present. Finally, I briefly sketch an evolutionary approach to understanding scientific development that contrasts with Gopnik and Meltzoff's. (shrink)

This article traces the principles and practices that characterized the American democratic republic and American culture at its Founding and suggests possible inherent weaknesses in our Founding thought and outlook that may have paved the way for a later transformation and decay of the American political order.

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.

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 writes that the Democratic party has increasingly embraced the agenda of the left, been tolerant of violence by radical organizations, been willing to compromise the principle of the rule of law, and shown increasing intolerance of opposing perspectives and a tendency to political repression.

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 February 3, 2013. It discusses the ongoing assault by secularist groups to cleanse American public life of any vestiges of religion. This radical separationism, which had its roots in the post-Civil War period and essentially was embraced by the U.S. Supreme Court in its long line of establishment clause decisions, is completely (...) contrary to the thinking of the Founding Fathers and the predominant culture of earlier America. Krason calls for a renewed effort, at different levels, to reclaim America’s historically religious and Christian culture. (shrink)

This article is one of SCSS President Stephen M. Krason’s “Neither Left nor Right, but Catholic” online columns. It makes the argument, in accord with such principles of Catholic social teaching as subsidiarity, that government should undertake tasks in a political society only when truly necessary. It points to many problems that experience has shown in the U.S. tend to develop when functions are turned over to government, especially in domestic areas. He made a presentation based on this column (...) as part of a panel on “What the Role of Government in Contemporary America Should Be, in Light of Historical Experience and Catholic Social Teaching” at the 2011 SCSS National Meeting-Conference.

There are a number of competing hypotheses about human evolution. For example, Homo habilis and Homo erectus could have existed together, or one could have evolved from the other, and paleontological evidence may allow us to decide between these two hypotheses (see, e.g., Spoor et al., 2007). For most who work on the biology of human behavior, there is no question that human behavior is in some large part a product of evolution. But, there are competing hypotheses in this area (...) as well. Some claim that human behavior is produced by a collection of psychological mechanisms, for the most part, and that these mechanisms are adaptations that arose in the Pleistocene Epoch (e.g., Tooby & Cosmides, 1992; Buss, 2007). The claim is important and testable (although, more difficult to test than the above mentioned hypotheses about origins); but importantly, it is only one among many hypotheses about the evolutionary origins of human behavior. While I think that there may be components of our behavior that are best explained by appealing to processes or mechanisms that arose in the Pleistocene, I think that human behavior is a result of evolutionary processes both much older and more recent than the Pleistocene. I also maintain that much of human behavior, and the mechanisms underlying it, could still be subject to evolutionary.. (shrink)

This was one of SCSS president Stephen M. Krason’s “Neither Left nor Right, but Catholic” columns that appeared in Crisismagazine.com and The Wanderer. At a time when there is increased discussion about the need for criminal justice reform, he points to several areas that must be addressed: overcriminalization, vagueness of laws, the decline of mens rea, too much readiness on the part of American police to arrest, excessive incarceration, and prosecutorial abuse.

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)

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.
