Introduction to an issue on moral and scientific realism in honor of Richard N. Boyd and Nicholas L. Sturgeon (Elizabeth S. Radcliffe, guest editor).

Computational models will play an important role in our understanding of human higher‐order cognition. How can a model's contribution to this goal be evaluated? This article argues that three important aspects of a model of higher‐order cognition to evaluate are (a) its ability to reason, solve problems, converse, and learn as well as people do; (b) the breadth of situations in which it can do so; and (c) the parsimony of the mechanisms it posits. This article argues that fits of (...) models to quantitative experimental data, although valuable for other reasons, do not address these criteria. Further, using analogies with other sciences, the history of cognitive science, and examples from modern‐day research programs, this article identifies five activities that have been demonstrated to play an important role in our understanding of human higher‐order cognition. These include modeling within a cognitive architecture, conducting artificial intelligence research, measuring and expanding a model's ability, finding mappings between the structure of different domains, and attempting to explain multiple phenomena within a single model.

This is an introductory book that targets the reader who has the ambition to apply economic analysis but may be missing a technical introduction to its mathematical techniques or seeks a structured elaboration of its philosophical principles. The book juxtaposes economic analysis with moral philosophy, political theory, egalitarianism, and other methodological principles and then passes to the details of methods such as model-building, derivatives, differential equations, statistical tests, and the use of computer programs.

This book opens with a simple introduction to financial markets, attempting to understand the action and the players of Wall Street by comparing them to the action and the players of main street. Firstly, it explores the definition of a security by its function, the departure from the buyer beware environment of corporate law and the entrance into the seller disclose environment of securities law. Secondly, it shows that the cost of disclosure rules is justified by their capacity to combat (...) irrationalities, fads, and panics. The third section explains how the structure of class actions is designed to improve deterrence. Next it explores the economic harm from insider trading and how the law fights it. In sum, the book shows how all these parts of securities law serve the virtuous cycle from liquidity to accurate prices and more trading and how the great recession showed that our securities regulation reacted mostly adequately to the crisis.

This essay aims to identify a semiotic consciousness found in New England Transcendentalism, consisting of the worldview that signs are pervasively present throughout nature and society. It finds that this worldview exists as a historical strand of thought stretching through the 19th century and, ultimately, further beyond, thereby making up an early movement in American semiotics. In this context, I furthermore see Transcendentalist thought informing the backdrop of Charles Peirce’s groundbreaking theory of signs later in the century, especially his metaphysical (...) claims about a “universe... perfused with signs”1 (1906: EP 2.394). In order to bring into full view the presence of a semiotic consciousness in Transcendentalism, I first address the intellectual history and genealogical roots that helped shape the minds of the Transcendentalists. Relevant influences include those both local to New England and imported from abroad, in particular the theologies of Jonathan Edwards and of Emanuel Swedenborg. Next, I directly examine the ideas of the figurehead of the Transcendentalist movement, Ralph Waldo Emerson, together with his Concord peers, Amos Bronson Alcott and Henry David Thoreau. Taking them as my case studies, I track the different ways a like-minded interest in signs takes shape within their individual projects. Focus-ing on their descriptions of nature, we find it in their experiences of the natural environment, their understanding of phenomena as representational and poetic, and their belief in the dialogical sharing of ideas across minds and species. Along the way, I further work out some of the aspects of a general theory of signs identifi-able within the Transcendentalist perspective, as well as distinguish it from other theoretical alternatives. Ultimately, I contend that the Transcendentalists held a similar idea of nature existing as a sign representing deep and varied meanings. (shrink)

The Mind and Heart of Ralph Waldo Emerson in World Perspective All serious readers of Emerson’s writings will gain insight from Joseph Urbas’s “historical reconstruction” of Emerson’s bottom-line philosophical commitments. By closely engaging an exceptionally wide breadth of primary material – one simply unseen in previous philosophical interpretations of Emerson – The Philosophy of Ralph Waldo Emerson brings to bear the weight of his published and unpublished corpus on the topics of metaphys...

In multiple autobiographical sketches, Charles S. Peirce identifies New England Transcendentalism as an essential part of his intellectual biography. A well-known instance is the passage opening "The Law of Mind" that identifies the setting of his childhood and early education within "the neighborhood of Concord": I may mention, for the benefit of those who are curious in studying mental biographies, that I was born and reared in the neighborhood of Concord,—I mean in Cambridge,—at the time when Emerson, Hedge, and their (...) friends were disseminating the ideas that they had caught from Schelling, and Schelling from Plotinus, from Boehm, or from God knows what minds stricken with the monstrous mysticism of the East....

travel, emerson often insisted, is only for the fool-hearted. He said it so many times in his popular essays and public lectures, he had actually gained a reputation for it. [It] is a fool's paradise. Our first journeys discover to us the indifference of places. At home I dream that at Naples, at Rome, I can be intoxicated with beauty, and lose my sadness. I pack my trunk, embrace my friends, embark on the sea, and at last wake up in (...) Naples, and there beside me is the stern fact, the sad self, unrelenting, identical, that I fled from. I seek the Vatican, and the palaces. I affect to be intoxicated with sights and suggestions, but I am not intoxicated. My giant goes with me wherever I go.... (shrink)

In 1887 the Open Court Publishing Company had its founding in a philosophy of monism. The company’s proprietor Edward C. Hegeler began the enterprise in an effort to promote his personal philosophic, religious, and moral ideas. He believed that these ideas could be conciliated with the growing scientific trends of the late nineteenth century, and that monism was the intellectual framework for doing so. Paul Carus, the editor of the journals The Open Court and The Monist, joined Hegeler as an (...) intellectual ally in this regard. For thirty years he openly defended the doctrines of monism in countless articles and books, successfully grounding the Open Court on this philosophy. This paper uncovers the historical development of the philosophical origin of the Open Court as it began with Hegeler’s personal religious motives, his ideological tension with the original editor Benjamin Underwood, and his embrace of the monistic writings of Paul Carus. It also examines Hegeler’s and Carus’s publications and personal letters from the 1880s and 1890s in order to determine the fundamental doctrines of their unique sense of monism. In Carus’s writings in particular is proposed a monism of causality that is compatible with a deterministic worldview and a unitary conception of the sciences. Also, both Carus and Hegeler propose a monistic ethics of meliorism that conceives the diverse periods of human history to be evolving toward the one final end of the moral improvement of humankind. While these are the positive doctrines that they accept, they further reject the antitheses of philosophical dualism and irreligious attitude of agnosticism of all varieties. (shrink)

Na história da filosofia americana, há um filão de pensamento sobre os signos na natureza. Animais, insetos, árvores, flores, o clima, paisagens e a noite estrelada são todos encontrados expressivos de diversos significados. Além disso, esses fenômenos naturais são considerados por pensadores, como Ralph Waldo Emerson e Charles S. Peirce, como dotados de um caráter representativo no seu núcleo ontológico. A minha apresentação baseia-se nesta tradição, explorando a semiose da natureza em toda a sua extensão e no que diz respeito (...) ao seu ser fundamental. O seu objetivo é desvendar alguns fundamentos metafísicos que apoiariam a semiose universal, bem como defender a primazia de uma dimensão estética no centro da atividade semiótica. (shrink)

Psychopathy is a personality disorder characterized by emotional deficits and a failure to inhibit impulsive behavior and is often subdivided into “primary” and “secondary” psychopathic subtypes. The maladaptive behavior related to primary psychopathy is thought to reflect constitutional “fearlessness,” while the problematic behavior related to secondary psychopathy is motivated by other factors. The fearlessness observed in psychopathy has often been interpreted as reflecting a fundamental deficit in amygdala function, and previous studies have provided support for a low-fear model of psychopathy. (...) However, many of these studies fail to use appropriate screening procedures, use liberal inclusion criteria, or have used unconventional approaches to assay amygdala function. We measured brain activity with BOLD imaging in primary and secondary psychopaths and non-psychopathic control subjects during Pavlovian fear conditioning. In contrast to the low-fear model, we observed normal fear expression in primary psychopaths. Psychopaths also displayed greater differential BOLD activity in the amygdala relative to matched controls. Inverse patterns of activity were observed in the anterior cingulate cortex (ACC) for primary versus secondary psychopaths. Primary psychopaths exhibited a pattern of activity in the dorsal and ventral ACC consistent with enhanced fear expression, while secondary psychopaths exhibited a pattern of activity in these regions consistent with fear inhibition. These results contradict the low-fear model of psychopathy and suggest that the low fear observed for psychopaths in previous studies may be specific to secondary psychopaths. (shrink)

Many frameworks exist that explain how people interact with avatars. Our core argument is that the primary theoretical mechanisms of a user-avatar bond rest with the way people engage avatars and, thereby, the broader digital environment. To understand and predict such engagement, we identify a person’s skill in handling/engaging the avatar in the digital environment as an ordering parameter. Accordingly, we define skill as a person’s ability to enact their agency successfully to achieve desired states. To explain how skill orders (...) experience, we ground our theorizing in ecological perception and systems theory. In our explication, we describe how stable action coupling enables a state of embeddedness in the digital environment. Then, we explain how embeddedness promotes motivational attunement and what the digital environment affords to users at different levels of skill. Throughout, we consider how our theoretical scaffolding generates tractable contentions regarding how skill influences UABs. (shrink)

The COVID-19 pandemic has brought the live music industry to an abrupt halt; subsequently, musicians are looking for ways to replicate the live concert experience virtually. The present study sought to investigate differences in aesthetic judgments of a live concert vs. a recorded concert, and whether these responses vary based on congruence between musical artist and piece. Participants made continuous ratings of their felt pleasure either during a live concert or while viewing an audiovisual recorded version of the same joint (...) concert given by a university band and a United States Army band. Each band played two pieces: a United States patriotic piece and a non-patriotic piece. Results indicate that, on average, participants reported more pleasure while listening to pieces that were congruent, which did not vary based on live vs. lab listening context: listeners preferred patriotic music when played by the army band and non-patriotic music when played by the university band. Overall, these results indicate that felt pleasure in response to music may vary based on listener expectations of the musical artist, such that listeners prefer musical pieces that “fit” with the particular artist. When considering implications for concerts during the COVID-19 pandemic, our results indicate that listeners may experience similar degrees of pleasure even while viewing a recorded concert, suggesting that virtual concerts are a reasonable way to elicit pleasure from audiences when live performances are not possible.

ABSTRACTDespite interest in exercise as a treatment for anxiety disorders the mechanism behind the anxiolytic effects of exercise is unclear. Two observations motivate the present work. First, engagement of attention control during increased working memory load can decrease anxiety. Second, exercise can improve attention control. Therefore, exercise could boost the anxiolytic effects of increased WM load via its strengthening of attention control. Anxiety was induced by threat of shock and was quantified with anxiety-potentiated startle. Thirty-five healthy volunteers participated in two (...) types of activity, exercise and control-activity. After each activity, participants completed a WM task at low- and high-load during safe and threat. Results were not consistent with the hypothesis: exercise vs. control-activity increased APS in high-load. However, this incre... (shrink)

In Reason, Tradition, and the Good, Jeffery L. Nicholas addresses the failure of reason in modernity to bring about a just society, a society in which people can attain fulfillment. Developing the critical theory of the Frankfurt School, Nicholas argues that we rely too heavily on a conception of rationality that is divorced from tradition and, therefore, incapable of judging ends. Without the ability to judge ends, we cannot engage in debate about the good life or the proper (...) goods that we as individuals and as a society should pursue. Nicholas claims that the project of enlightenment—defined as the promotion of autonomous reason—failed because it was based on a deformed notion of reason as mere rationality, and that a critical theory of society aimed at human emancipation must turn to substantive reason, a reason constituted by and constitutive of tradition. To find a reason capable of judging ends, Nicholas suggests, we must turn to Alasdair MacIntyre’s Thomistic-Aristotelianism. Substantive reason comprises thinking and acting on the set of standards and beliefs within a particular tradition. It is the impossibility of enlightenment rationality to evaluate ends and the possibility of substantive reason to evaluate ends that makes the one unsuitable and the other suitable for a critical theory of society. Nicholas’s compelling argument, written in accessible language, remains committed to the promise of reason to help individuals achieve a good and just society and a good life. This requires, however, a complete revolution in the way we approach social life. “Jeffery Nicholas has written an important and valuable book that invites its readers to discover the difficulties of late modern Western thought from the perspective of twentieth-century critical theory, and to consider a response to those difficulties drawn from the work of Alasdair MacIntyre and Charles Taylor.” —Christopher Stephen Lutz, Saint Meinrad Seminary and School of Theology.

The argument between Jacques Maritain and Charles de Koninck over the primacy of the common good is well known. Yet, even though Mary Keys has carefully arbitrated this debate, it still remains problematic for Alasdair MacIntyre, particularly because of the role rights play in both Maritain and Catholic Social Thought. I examine Keys’ argument and, in addition, Deborah Wallace’s account of MacIntyre’s criticism of rights in Catholic social thought. I argue, in the end, that what Maritain, and in consequence Keys (...) and Wallace, miss about the common good is its relationship to practical reasoning, and that MacIntyre highlights both that relationship and the role of the common good in human dignity.

As environmental concerns rightly take a greater role in the critical reevaluation of the American philosophical tradition, it behooves us to return again to the often slippery notion of “nature” to ask if it can be redeemed as not merely the canvas on which human endeavor is depicted but an active element of the diverse and distinct philosophical perspectives that make the tradition. Indeed, there is a great need to depict the potentially subversive ways that human and nature can be (...) understood as radically connatural, in intimate ecological and constructive relations that make nature not just the instrument for the exertion for human wants and desires but also thoroughly and...

This article deals with a highly debated text, namely 2 Maccabees 12, specifically the problematic verses (38–45) which contain a theology that is distinctly non-Jewish in import. Indeed, most recent scholars concerned with this passage do not seem to be unanimous apropos the best interpretation of the events that are described, resulting in a range of different opinions concerning, inter alia, the afterlife, purgatory and/or doctrinal disputes between Pharisees and Sadducees. By means of an interpretivist or constructivist epistemology, the authors (...) advocate that normally, traditional Judaism emphasises personal, individual responsibility and accountability, whereas in this text God is portrayed as requiring material, financial payment for wrongdoing and not individual תשובה [teshuvah]. This is in contradistinction to, inter alia, Exodus 30:11–16 and theologically Jewish ‘transgression’ has clearly metamorphosed into Christian ‘sin’. In addition, Judas Maccabeus seems to have retained a half-shekel methodology (employed for Jewish men of military age – soldiers) whilst emphasising the ‘atonement for your lives’ from Exodus 30:11–16 in a more literalistic, materialistic, non-Jewish sense whilst de-emphasising the real need to maintain the Temple as well as the proper, traditional rules of תשובה.

Acoustical changes in the prosody of mothers’ speech to infants are distinct and near universal. However, less is known about the visible properties of mothers’ infant-directed (ID) speech, and their relation to speech acoustics. Mothers’ head movements were tracked as they interacted with their infants using ID speech, and compared to movements accompanying their adult-directed (AD) speech. Movement measures along three dimensions of head translation, and three axes of head rotation were calculated. Overall, more head movement was found for ID (...) than AD speech, suggesting that mothers exaggerate their visual prosody in a manner analogous to the acoustical exaggerations in their speech. Regression analyses examined the relation between changing head position and changing acoustical pitch ( F0 ) over time. Head movements and voice pitch were more strongly related in ID speech than in AD speech. When these relations were examined across time windows of different durations, stronger relations were observed for shorter time windows (< 5 sec). However, the particular form of these more local relations did not extend or generalize to longer time windows. This suggests that the multimodal correspondences in speech prosody are variable in form, and occur within limited time spans. (shrink)
