This volume is a collection of essays by various contributors in honor of the late Laurence Berns, Richard Hammond Elliot Tutor Emeritus at St. John's College, Annapolis. The essays address the literary, political, theological, and philosophical themes of his life's work as a scholar, teacher, and constant companion of the "great books.".

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:HUME ON BLAME AND EXCUSE17. Hume's account of blame and excuse differs in fundamental respects from many contemporary ones. Many contemporary views, ultimately derived from the Kantian dictum that 'ought' implies 'can', base excuses on the nonvoluntary character of an action. For example, H. L. A. Hart argues that the basic requirements for responsibility are that a person have the capacity and a fair opportunity to do what (...) is required. A person is to be excused for an action if he lacked either the capacity or opportunity to do what was required. As these are conditions for an action being voluntary in a suitably narrow sense, Hart primarily bases excuses on the nonvoluntary character of actions. Likewise, Richard Brandt's view, which in many respects is similar to Hume's, requires that the manifestation of a character trait be subject to a high degree of voluntary control before blame.2 is appropriate. Hume, however, explicitly denies that either a character trait or its manifestation in conduct need be subject to voluntary control for blame to be appropriate. The nonvoluntary character of an action does not necessarily excuse one from blame. Hume makes four key claims about blame and excuse. (1) The ultimate objects of praise and blame are mental qualities, not actions. (2) Actions are considered only as signs of mental qualities. (3) The possession and expression of these mental qualities may be appropriate objects of praise or blame even if they are nonvoluntary. (4) Persons have excuses if their actions do not indicate enduring mental qualities. These points need to be substantiated and explained. The first two claims may be considered together. That Hume holds mental qualities are the ultimate objects of praise and blame and that actions are considered only as signs of mental qualities is indisputable. 18. 'Tis evident, that when we praise any actions, we regard only the motives that produced them, and consider the actions as signs or indications of certain principles in the mind and temper. The external performance has no merit. We must look within to find the moral quality. This we cannot do directly; and therefore fix our attention on actions, as on external signs. But these actions are still considered as signs; and the ultimate object of our praise and approbation is the motive, that produced them. For present purposes, only two points need be noted about this passage. First, it clearly states that the ultimate objects of praise and, as he indicates in his following 4 paragraph, blame are always mental qualities. The expression mental qualities is vague, perhaps deliberately so. Sometimes Hume uses the term motive instead. By 'motive' he does not intend any passing desire or further intention which one may have in acting, e.g., embarrassing others. For Hume, some motives are not even dispositions to act. Second, actions or external performances have no merit. They are only signs of mental qualities. Even if the concept of an action includes more than the external behavior, such as the intention, it does not include motives or desires. A difference in intention may entail a difference in action, but a difference in motive does not. The same action may be performed from different motives. Hence, actions are not logically connected with the objects of praise and blame. Hume's claim that actions themselves have no merit, it might be objected, is incorrect. People do constantly evaluate actions. If they did not, then actions would not be considered untoward and a basis for attributing blame. However, Hume does not deny that actions may be evaluated in some way or other, only that they alone have merit or are appropriate objects of praise and blame. Actions may be evaluated without reference to mental qualities, for example, as right or wrong, useful or unuseful. Hume is 19. chiefly concerned with evaluating actions as virtuous or vicious. The terms virtuous and vicious as applied to actions involve an element of praise and blame, whereas the terms right and wrong, at least in most of their uses, do not. Thus, Hume is not denying that actions alone may have merit in the sense of value or utility. Rather, he is denying that actions... (shrink)

Roger White argued for a principle of indifference. Hart and Titelbaum showed that White’s argument relied on an intuition about conditioning on biconditionals that, while widely shared, is incorrect. Hawthorne, Landes, Wallmann, and Williamson argue for a principle of indifference. Remarkably, their argument relies on the same faulty intuition. We explain their intuition, explain why it’s faulty, and show how it generates their principle of indifference. 1Introduction 2El Caminos and Indifference 2.1Overview 2.2Fins and antennas 2.3HLWW in the example 2.4The (...) restrictiveness of Condition 2 2.5Summary 3The Specifics of HLWW s Argument 3.1Mapping their conditions to our equations 3.2HLWW’s responses to objections.

Evolutionary ethics - the application of evolutionary ideas to moral thinking and justification - began in the nineteenth century with the work of Charles Darwin and Herbert Spencer, but was subsequently criticized as an example of the naturalistic fallacy. In recent decades, however, evolutionary ethics has found new support among both the Darwinian and the Spencerian traditions. This accessible volume looks at the history of thought about evolutionary ethics as well as current debates in the subject, examining first the claims (...) of supporters and then the responses of their critics. Topics covered include social Darwinism, moral realism, and debunking arguments. Clearly written and structured, the book guides readers through the arguments on both sides, and emphasises the continuing relevance of evolutionary theory to our understanding of ethics today.

Contributors in the order of contributions: David Ebrey, Richard Kraut, T. H. Irwin, Leonard Brandwood, Eric Brown, Agnes Callard, Gail Fine, Suzanne Obdrzalek, Gábor Betegh, Elizabeth Asmis, Henry Mendell, Constance C. Meinwald, Michael Frede, Emily Fletcher, Verity Harte, Rachana Kamtekar, and Rachel Singpurwalla. -/- The first edition of the Cambridge Companion to Plato (1992), edited by Richard Kraut, shaped scholarly research and guided new students for thirty years. This new edition introduces students to fresh approaches to Platonic (...) dialogues while advancing the next generation of research. Of its seventeen chapters, nine are entirely new, written by a new generation of scholars. Six others have been thoroughly revised and updated by their original authors. The volume covers the full range of Plato's interests, including ethics, political philosophy, epistemology, metaphysics, aesthetics, religion, mathematics, and psychology. Plato's dialogues are approached as unified works and considered within their intellectual context, and the revised introduction suggests a way of reading the dialogues that attends to the differences between them while also tracing their interrelations. The result is a rich and wide-ranging volume which will be valuable for all students and scholars of Plato. (shrink)

The Origin of Species by Charles Darwin is universally recognized as one of the most important science books ever written. Published in 1859, it was here that Darwin argued for both the fact of evolution and the mechanism of natural section. The Origin of Species is also a work of great cultural and religious significance, in that Darwin maintained that all organisms, including humans, are part of a natural process of growth from simple forms. This Companion commemorates the 150th anniversary (...) of the publication of the Origin of Species and examines its main arguments. Drawing on the expertise of leading authorities in the field, it also provides the contexts - religious, social, political, literary, and philosophical - in which the Origin was composed. Written in a clear and friendly yet authoritative manner, this volume will be essential reading for both scholars and students More broadly, it will appeal to general readers who want to learn more about one of the most important and controversial books of modern times.

No doubt most philosophers who spend time on the history of philosophy are familiar with that question asked to embarrass (and liable to be asked by scientists in particular) why the history of the subject should be thought a significant part of the subject itself. Either there is progress in philosophy, it is said, or there is not. If there is progress, why the laborious backward glances? How can the past be so important? Why aren’t philosophers like psychologists, given perhaps (...) a short historical orientation before being brought up to the nitty-gritty of the present? If, on the other hand, there is no progress, if we might as well be discussing Locke as Quine, doesn’t that imply that philosophy consists in a set of questions for which there is no way of establishing even that some answers are better than others? Wouldn’t it be more profitable to pursue questions to which at least provisional answers can be established, approximating to the truth? Wouldn’t it be better to be a scientist? (shrink)

This seriously playful book provides comic relief in an age of neoliberalism and argues that parody can be used to creatively benefit our practices of self-narration and quests for knowledge. It demonstrates how parody utilizes humor, play, and self-reflection to allow for a helpful, alternative relationship to mistakes and our multifaceted-self. The book works to delineate specific ways of viewing, studying, creating, and performing a particular form of humorous parody, and through pedagogical application, it balances practical hands on examples via (...) digital video creation with examples and exercises such as interrogating our creative histories and parodying them--either as a classroom exercise or in individual self-reflection. The core readership for this book is rhetoric and composition scholars researching continental philosophy, humor, and narrative theory, and it lends itself to classroom implementation for professors, as it brings together (often for the first time) major academic conversations on humor throughout philosophy, literary and cultural studies, communication studies, and media studies. Therefore, this book will be essential reading for undergraduate/graduate courses that feature humor, alternative forms of communication in the public sphere, alternative rhetorical strategies, and courses that focus on the importance of creativity and play in our daily lives and scholarship.

In 15 insightful essays, Jacques Derrida and an international group of scholars of religion explore postmodern thinking about God and consider the nature of forgiveness in relation to the paradoxes of the gift. Among the themes addressed by contributors are the possibilities of imagining God as unthinkable, imagining God as non-patriarchal, imagining a return to Augustine, and imagining an age in which praise is far more important than narrative. Questioning God moves readers beyond the parameters of metaphysical reason and modernist (...) rationality as it attempts to think the questions of God and forgiveness in a postmodernist context.

The ethical issues raised by cybersecurity practices and technologies are of critical importance. However, there is disagreement about what is the best ethical framework for understanding those issues. In this paper we seek to address this shortcoming through the introduction of a principlist ethical framework for cybersecurity that builds on existing work in adjacent fields of applied ethics, bioethics, and AI ethics. By redeploying the AI4People framework, we develop a domain-relevant specification of five ethical principles in cybersecurity: beneficence, non-maleficence, autonomy, (...) justice, and explicability. We then illustrate the advantages of this principlist framework by examining the ethical issues raised by four common cybersecurity contexts: penetration testing, distributed denial of service attacks (DDoS), ransomware, and system administration. These case analyses demonstrate the utility of this principlist framework as a basis for understanding cybersecurity ethics and for cultivating the ethical expertise and ethical sensitivity of cybersecurity professionals and other stakeholders.

Focused sequent calculi are a refinement of sequent calculi, where additional side-conditions on the applicability of inference rules force the implementation of a proof search strategy. Focused cut-free proofs exhibit a special normal form that is used for defining identity of sequent calculi proofs.

We also show a number of additional results. fD.LG is sound and complete w.r.t.

The Cambridge History of Seventeenth-Century Philosophy offers a uniquely comprehensive and authoritative overview of early-modern philosophy written by an international team of specialists. As with previous Cambridge histories of philosophy the subject is treated by topic and theme, and since history does not come packaged in neat bundles, the subject is also treated with great temporal flexibility, incorporating frequent reference to medieval and Renaissance ideas. The basic structure of the volumes corresponds to the way an educated seventeenth-century European might have (...) organised the domain of philosophy. Thus, the history of science, religious doctrine, and politics feature very prominently. The narrative that unfolds begins with an intellectual world dominated by a synthesis of Aristotelianism and scholastic philosophy, but by the end of the period the mechanistic or 'corpuscularian' philosophy has emerged and exerted its full impact on traditional metaphysics, ethics, theology, logic, and epistemology.

Acoustic signals serving intraspecific communication by predators are perceived by potential prey as warning signals. We analysed the acoustic characteristics of howling of wolves and found a striking similarity to the warning sounds of technical sirens. We hypothesize that the effectivity of sirens as warning signals has been enhanced by natural sensory predisposition of humans to get alerted by howling of wolves, with which they have a long history of coexistence. Psychoacoustic similarity of both stimuli seems to be supported by (...) the fact that wolves and dogs perceive the sound of technical sirens as a relevant releasing supernormal stimulus and reply to it with howling. Inspiration by naturally occurring acoustic aposematic signals might become an interesting example of biomimetics in designing new warning sound systems. (shrink)

Energy innovation offers us our best chance to solve the three urgent and interrelated problems of climate change, worldwide insecurity over energy supplies, and rapidly growing energy demand. But if we are to achieve a timely transition to reliable, low-cost, low-carbon energy, the U.S. energy innovation system must be radically overhauled. Unlocking Energy Innovation outlines an up-to-the-minute plan for remaking America's energy innovation system by tapping the country's entrepreneurial strengths and regional diversity in both the public and private spheres. The (...) authors map three waves of energy innovation to show how we can speed up the introduction of new technologies and business models and accelerate their deployment on a massive scale. "Business as usual" will not fill the energy innovation gap. Nor will wishful thinking--common enough today, with politicians and others talking up some technologies, talking down others, and claiming that if we price it, or if we mandate it, or if we simply say it often and inspiringly enough, the innovations will flow. Only the kind of systemic, transformative changes to our energy innovation system described in this provocative book will help us avert the most dire scenarios and achieve a sustainable and secure energy future.

When it first appeared in 1979, Philosophy and the Mirror of Nature hit the philosophical world like a bombshell. In it, Richard Rorty argued that, beginning in the seventeenth century, philosophers developed an unhealthy obsession with the notion of representation: comparing the mind to a mirror that reflects reality. Rorty's book is a powerful critique of this imagery and the tradition of thought that it spawned. Thirty years later, the book remains a must-read and stands as a classic of (...) twentieth-century philosophy. Its influence on the academy, both within philosophy and across a wide array of disciplines, continues unabated.

There are many kinds of epistemic experts to which we might wish to defer in setting our credences. These include: highly rational agents, objective chances, our own future credences, our own current credences, and evidential probabilities. But exactly what constraint does a deference requirement place on an agent's credences? In this paper we consider three answers, inspired by three principles that have been proposed for deference to objective chances. We consider how these options fare when applied to the other kinds (...) of epistemic experts mentioned above. Of the three deference principles we consider, we argue that two of the options face insuperable difficulties. The third, on the other hand, fares well|at least when it is applied in a particular way. (shrink)

To me it seemed that pedagogy simply described various specific strategies and techniques employed in the formal classroom. But after all these years with McDermott, I now think I understand better.

Sainsbury and Tye present a new theory, 'originalism', which provides natural, simple solutions to puzzles about thought that have troubled philosophers for centuries.

Rudolf Carnap is increasingly regarded as one of the most important philosophers of the twentieth century. He was one of the leading figures of the logical empiricist movement associated with the Vienna Circle and a central figure in the analytic tradition more generally. He made major contributions to philosophy of science and philosophy of logic, and, perhaps most importantly, to our understanding of the nature of philosophy as a discipline. In this volume a team of contributors explores the major themes (...) of his philosophy and discusses his relationship with the Vienna Circle and with philosophers such as Frege, Husserl, Russell, and Quine. New readers will find this the most convenient and accessible guide to Carnap currently available. Advanced students and specialists will find a conspectus of recent developments in the interpretation of Carnap. (shrink)

Clustered regularly interspaced short palindromic repeats genome editing has already reinvented the direction of genetic and stem cell research. For more complex diseases it allows scientists to simultaneously create multiple genetic changes to a single cell. Technologies for correcting multiple mutations in an in vivo system are already in development. On the surface, the advent and use of gene editing technologies is a powerful tool to reduce human suffering by eradicating complex disease that has a genetic etiology. Gene drives are (...) CRISPR mediated alterations to genes that allow them to be passed on to subsequent populations at rates that approach one hundred per cent transmission. Therefore, from an anticipatory biomedical ethics perspective, it is possible to conceive gene drive being used with CRISPR to permanently ameliorate aberrant genes from wild-type populations containing mutations. However, there are also a number of possible side effects that could develop as the result of combining gene editing and gene drive technologies in an effort to eradicate complex diseases. In this paper, we critically analyse the hypothesis that the combination of CRISPR and gene drive will have a deleterious effect on human populations from an ethical perspective by developing an anticipatory ethical analysis of the implications for the use of CRISPR together with gene drive in humans.

My topic is authenticity in or perhaps as painting, not the authenticity of paintings; I know next to nothing about the problem of verifying claims of authorship. I am interested in another kind of genuineness and fraudulence, the kind at issue when we say of a person that he or she is false, not genuine, inauthentic, lacks integrity, and, especially when we say he or she is playing to the crowd, playing for effect, or is a poseur. These are not (...) quite moral distinctions (no one has a duty to be authentic), but they are robustly normative appraisals, applicable even when such falseness is not a case of straight hypocrisy but of lack of self-knowledge or of self-deceit. (A person can be quite sincere and not realize the extent of her submission to the other’s expectations and demands.) This sort of appraisal also has a long history in post-Rousseauist reflections on the dangers of uniquely modern forms of social dependence, and they are prominent worries in the modern novel.

During the last 25 years, researchers studying human reasoning and judgment in what has become known as the “heuristics and biases” tradition have produced an impressive body of experimental work which many have seen as having “bleak implications” for the rationality of ordinary people (Nisbett and Borgida 1975). According to one proponent of this view, when we reason about probability we fall victim to “inevitable illusions” (Piattelli-Palmarini 1994). Other proponents maintain that the human mind is prone to “systematic deviations from (...) rationality” (Bazerman & Neale 1986) and is “not built to work by the rules of probability” (Gould 1992). It has even been suggested that human beings are “a species that is uniformly probability-blind” (Piattelli-Palmarini 1994). This provocative and pessimistic interpretation of the experimental findings has been challenged from many different directions over the years. One of the most recent and energetic of these challenges has come from the newly emerging field of evolutionary psychology, where it has been argued that it’s singularly implausible to claim that our species would have evolved with no “instinct for probability” and, hence, be “blind to chance” (Pinker 1997, 351). Though evolutionary psychologists concede that it is possible to design experiments that “trick our probability.. (shrink)

Central and East Europeans have a great deal in common, both historically and culturally, with West Europeans and North Americans, but tend to be more interdependent. Interdependence has been shown to be linked to holistic cognition. East Asians are more interdependent than Americans and are more holistic.

In two studies we found evidence that Central and East Europeans are indeed (...) more holistic than Westerners on three tasks, one of which examined categorization and two of which measured patterns of visual attention.

Many of today's ads work by arousing the viewer's emotions. Although emotion-arousing ads are widely used and are commonly thought to be effective, their careless use produces a side-effect: the psychoactive ad. A psychoactive ad is any emotion-arousing ad that can cause a meaningful, well-defined group of viewers to feel extremely anxious, to feel hostile toward others, or to feel a loss of self-esteem. We argue that, because some ill-conceived psychoactive ads can cause harm, ethical issues must arise during their (...) production. Current pretesting methods cannot identify the potentially psychoactive ads; therefore, we offer some tentative guidelines for reducing the number of viewers harmed by psychoactive ads. (shrink)
