Résumé Bien qu’il soit très peu pris en compte par l’histoire des ordinateurs, l’analyseur différentiel a été une machine mathématique essentielle – à la fois aux États-Unis et en Angleterre, puis dans d’autres pays européens – pour la résolution numérique des équations différentielles, avant et pendant la Seconde Guerre Mondiale. Douglas R. Hartree (1897-1958), initialement physicien de l’atome, est directement concerné par les nouvelles possibilités qu’offrent cet analyseur, ainsi que des machines comme l’ENIAC à Philadelphie et l’EDSAC à (...) Cambridge après la guerre. Toute sa carrière est consacrée à leur mise en pratique et à l’élaboration de méthodes mathématiques qui permettent d’en explorer toutes les potentialités, débouchant sur une nouvelle discipline, l’analyse numérique.

Can thought arise out of matter? Can self, soul, consciousness, “I” arise out of mere matter? If it cannot, then how can you or I be here? I Am a Strange Loop argues that the key to understanding selves and consciousness is the “strange loop”—a special kind of abstract feedback loop inhabiting our brains. The most central and complex symbol in your brain is the one called “I.” The “I” is the nexus in our brain, one of many symbols seeming (...) to have free will and to have gained the paradoxical ability to push particles around, rather than the reverse. How can a mysterious abstraction be real—or is our “I” merely a convenient fiction? Does an “I” exert genuine power over the particles in our brain, or is it helplessly pushed around by the laws of physics? These are the mysteries tackled in I Am a Strange Loop, Douglas Hofstadter's first book-length journey into philosophy since Gödel, Escher, Bach. Compulsively readable and endlessly thought-provoking, this is a moving and profound inquiry into the nature of mind. (shrink)

This research on the ethics of meaningful work examined how types of job-related harm and their magnitude of consequences influenced components of ethical decision-making. The research also investigated the moderating effects of individual differences on the relation between the MOC and the ethical decision-making elements for each type of harm. Using a sample of 185 Chinese professionals, a between-subjects, fully crossed experimental scenario design revealed that physical and economic job-related harm were recognized as moral issues to a greater extent than (...) cognitive or emotional harm. Second, physical job-related harm stimulated a higher level of moral evaluations than economic and cognitive harm. Third, individuals intended to act ethically when MOC was high versus low. Finally, experience with layoffs and IMO helped explain the relations between MOC and moral evaluations for economic and cognitive job-related harm, respectively. Implications for research and management are discussed. (shrink)

AbstractOrganizations receive multiple benefits when their members act ethically. Of interest in this study is if the actors receive benefits as well, especially as individuals look to work to fulfill psychological and social needs in addition to economic ones. Specifically, we highlight a series of ongoing ethical practices embodied in professional moral courage and their relationship to actor’s work meaningfulness and life well-being. Drawing on self-determination theory and affective events theory, we explore how exercising professional moral courage in one’s work (...) leads to positive work and life outcomes. Data from 106 administrative staff of non-profit organizations demonstrates the positive benefits of adopting ethical practices at work. Specifically, professional moral courage is found to be significantly related to both work meaningfulness and individual eudaimonic life well-being. Our findings note positive benefits for individuals who incorporate professional moral courage into their daily lives and provide support for organizations seeking to encourage it from their employees; benefits for organizations and employees go beyond just the gains from ethical behavior into other positive psychological processes. Implications for future work that considers both the psychological and normative approaches to meaningful work are discussed. (shrink)

The Issues at Issue: Heidegger declares metaphor to be a function of metaphysics. Ricoeur's tension theory of metaphor takes the understanding of metaphor beyond metaphysics. Ricoeur's theory of metaphor is a theory of metaphorical statement not of naming. The classical, lexical theory of metaphor focuses on a primary meaning of each metaphor. As such metaphor is merely ornamentation in language. What it names could more appropriately be accomplished in literal language. In contrast, metaphor is understood by Ricoeur to be a (...) semantic event made possible by three kinds of tensions. One may understand symbols to function with the same metaphorical tensions. In the case of symbols, however, these tensions function not at the level of the sentence but rather of the narrative. Metaphor and symbol both have an ‘ontological priority’ over other elements of discourse and experience. They ‘work’ because of the event character of both understanding and experience. Understanding and experience have event as their condition of possibility. Metaphor and symbol both have a ‘temporal priority’, as well, for they serve as the shock to think ‘more’. This can occur, however, because they are part of a circularity that is non-metaphysical, that is, the circularity of the event character of the Being-of beings. Hence, just as metaphors are always ‘larger’ than the sentence, so are symbols always ‘larger’ than the narrative. (shrink)

This article borrows from the american tradition of emerson, james, and peirce to argue that religious belief may properly originate in feeling, willing, or reasoning. i also maintain that such belief is not consummated until all three aspects of one's being--feeling, willing, and thinking--have been addressed. this approach both democratizes the possibility of religious belief and requires of full belief that it be applicable to all aspects of one's life.

Under the influence of rationalism and various forms of absolute idealism in the nineteenth century, teleology took on the nature of fixity; the universe was held to be fulfilling a definite telos. Such teleology defined a closed universe. In the latter half of the same century the American pragmatists, under the influence of Bergson and Renouvier, began to develop their notion of an open universe: one whose possibilities were not predetermined but were evolving creatively. This necessarily involved a change in (...) the understanding of teleology as reflected, for example, in C. S. Peirce’s 1892 account of “developmental teleology.” These changes in turn led to the “open universe” views of Whitehead, Hartshorne, and process theology in general. Within this historical framework one view which deserves some recognition for its role in this transition is often overlooked, that is, the personalism of Borden Parker Bowne. Bowne’s personalism suggests both the need for redefining teleology and two possible avenues for accomplishing such redefinition. (shrink)

In 1856, the English photographer Francis Frith set out on the first of three tours of Egypt and the Holy Lands. Traveling up the Nile and then on to the Sinai, Palestine, Syria, and Lebanon, Frith systematically crafted exquisite pictures of ruins, landscapes, and legendary sites. He then published his views in England and America in a variety of formats, becoming something of a celebrity in photographic circles. This book, the first to place Frith's Egyptian and Levantine images in cultural (...) context, reveals the distinct meanings these ostensibly "topographic" pictures held for the photographer and his Victorian audience. A Quaker by birth and an entrepreneur by nature, Frith brought to his photographic projects a sense of mission: to revive and confirm the stories of the Bible, while offering the region to armchair travelers as a seamless Oriental milieu of Romantic reverie. Francis Frith in Egypt and Palestine narrates the political, intellectual, and social concerns that make Frith representative of England's encounter with the East in the nineteenth century. Historian of photography Douglas R. Nickel brings a sophisticated interdisciplinary approach to bear on the subject in order to expose the complexity of Frith's image-making, setting the photographs against a Victorian backdrop of religious debate, imperialist thought, Romantic philosophy, and Pre-Raphaelite aesthetics.

I argue that Plato believes that the soul must be both the principle of motion and the subject of cognition because it moves things specifically by means of its thoughts. I begin by arguing that the soul moves things by means of such acts as examination and deliberation, and that this view is developed in response to Anaxagoras. I then argue that every kind of soul enjoys a kind of cognition, with even plant souls having a form of Aristotelian discrimination (...) (krisis), and that there is therefore no completely unintelligent, evil soul in the cosmos that can explain disorderly motions; as a result, the soul is not the principle of all motion but only motion in the cosmos after it has been ordered by the Demiurge.

Not long before he died, Henry David Thoreau was asked by a friend where religion was to be found in his writings. Thoreau responded by saying that his religiosity pervaded his works but that no one noticed it. This result was enabled by the cultural belief that religiosity entailed formal religion, creeds, fixed rituals, and overt discussions of God or gods. Thoreau’s point—a development of Emerson’s “Divinity School Address”—was to show the mistakenness of this compartmentalization of one’s religious life. For (...) Thoreau, genuine religiosity pervades and marks every aspect of one’s being—body and soul. “Our life,” Thoreau wrote in his journal in 1840, “is but the Soul made known by its fruits, the ..

Off-shoring is a business decision increasingly being considered as a strategic option to effect expected cost savings. This exploratory study focuses on the moral recognition of off-shoring using ethical decision making embedded within affective events theory. Perceived magnitude of consequences and time pressure are hypothesized as affective event characteristics that lead to decision makers’ empathy responses. Subsequently, cognitive and affective empathy influence the decision makers’ moral recognition. Decision makers’ prior knowledge of off-shoring was also predicted to interact with perceptions of (...) the affective event characteristics to influence cognitive and affective empathy. Findings from a limited sample of human resource management professionals suggest that perceptions of magnitude of consequences and cognitive empathy directly relate to moral recognition and that affective empathy partially mediates the relationship between perceptions of the magnitude of consequences and moral recognition. The three-way interaction of the perceptions of magnitude of consequences, time pressure, and prior knowledge of off-shoring was marginally related to cognitive empathy. Interpretations of the findings, validity issues, limitations, future research directions, and management implications are provided. (shrink)

In this article, I argue that online echo chambers are in some cases and in some respects good. I do not attempt to refute arguments that they are harmful, but I argue that they are sometimes beneficial. In the first section, I argue that it is sometimes good to be insulated from views with which one disagrees. In the second section, I argue that the software-design principles that give rise to online echo chambers have a lot to recommend them. Further, (...) the opposing principle, serendipity, could give rise to serious harm, in light of the conclusion of the first section that sometimes we are better off being insulated from some content online. In the third section, I argue that polarization can be a useful tool for inculcating the appropriate attitudes in a person. (shrink)

This article is featured in a special issue dedicated to theme, "the human being in the digital era: awareness, critical thinking and political space in the age of the internet and artificial intelligence." In this article, I consider the way that social-media companies nudge us to spend more time on their platforms, and I argue that, in principle, these nudges are morally permissible: they are not manipulative and do not violate any obvious moral rules. The moral problem, I argue, is (...) not with nudging in principle but is instead with the fact that users are being nudged towards something bad for them. In practice, this often involves being nudged to spend an unhealthy amount of time using a social-media app or being nudged towards content that is bad for us, such as by promoting eating-disorder content to young girls. Since nudging is morally permissible, it is open to these companies to use the same technologies to nudge us towards the good. (shrink)

The American thinker Charles Sanders Peirce, best known as the founder of pragmatism, has been influential not only in the pragmatic tradition but more recently in the philosophy of science and the study of semiotics, or sign theory. Strands of System provides an accessible overview of Peirce's systematic philosophy for those who are beginning to explore his thinking and its import for more recent trends in philosophy.

Design and analysis of algorithms can be a difficult subject for students due to its sometimes-abstract nature and its use of a wide variety of mathematical tools. Here the author, an experienced and successful textbook writer, makes the subject as straightforward as possible in an up-to-date textbook incorporating various new developments appropriate for an introductory course. This text presents the main techniques of algorithm design, namely, divide-and-conquer algorithms, greedy algorithms, dynamic programming algorithms, and backtracking. Graph algorithms are studied in detail, (...) and a careful treatment of the theory of NP-completeness is presented. In addition, the text includes useful introductory material on mathematical background including order notation, algorithm analysis and reductions, and basic data structures. This will serve as a useful review and reference for students who have covered this material in a previous course. Features The first three chapters provide a mathematical review, basic algorithm analysis, and data structures. Detailed pseudocode descriptions of the algorithms along with illustrative algorithms are included. Proofs of correctness of algorithms are included when appropriate. The book presents a suitable amount of mathematical rigor. After reading and understanding the material in this book, students will be able to apply the basic design principles to various real-world problems that they may encounter in their future professional careers.

I argue that, according to Plato, the body is the sole cause of psychic disorders. This view is expressed at Timaeus 86b in an ambiguous sentence that has been widely misunderstood by translators and commentators. The goal of this article is to offer a new understanding of Plato’s text and view. In the first section, I argue that although the body is the result of the gods’ best efforts, their sub-optimal materials meant that the soul is constantly vulnerable to the (...) body’s influences. In the second section, I argue that every psychic disorder is a disruption of the motions of the inner psychic circles by the body; moreover, I defend my translation of 86b. In the final section, I argue that the goal of education is to restore the circles to their original orbits, and I disarm a possible objection that bad education is also a cause of psychic disorder.

This article concerns the place of Plato’s eschatology in his philosophy. I argue that the theory of reincarnation appeals to Plato due to its power to explain how non-human animals came to be. Further, the outlines of this theory are entailed by other commitments, such as that embodiment disrupts psychic functioning, that virtue is always rewarded and vice punished, and that the soul is immortal. I conclude by arguing that Plato develops a view of reincarnation as the chief tool that (...) the gods have to ensure that virtue is victorious over vice throughout the whole cosmos. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What I Think about When I Think about Teaching Ethics: A Philosophical Exploration in Pedagogy1Douglas R. HochstetlerIntroductionIn his book, Philosophy Americana, Anderson outlines the basic tenets of those individuals in American philosophy known as pragmatists. The pragmatists “were not Enlightenment believers in the inevitability of progress,” Anderson writes, “but across the board the pragmatists were meliorists. They believed that inquiry and experiment could lead to the betterment of human (...) existence” (Philosophy Americana 28). Similarly, college professors seem to understand that progress is not inevitable in the classroom either. In fact, some of the most skeptical academics may even contend that students’ academic skills are deteriorating over time rather than improving (they may place the blame on high schools for poor preparation here). Rather than progress as a given, most faculty believe that their own inquiry and experimentation in the classroom may prove as fertile ground for the learning process. At their best and most impactful, they embody this pragmatic notion of meliorism, hopeful that their efforts will make a difference in the lives of their students.The American philosophical tradition encapsulates a variety of philosophical themes. Several stand out as ones that intersect with and potentially inform higher education pedagogy. In this introduction, I briefly highlight American philosophical themes related to the practice of teaching and learning. I follow this with the journal portion, with entries from a semester-long habit of recording my thoughts and observations related to pedagogy. The paper ends with reflections on the journal process itself.One theme pertinent to this topic is the aforementioned notion of meliorism. The pragmatists, in particular, held an underlying hope that life could improve with a requisite amount of effort and planning. As Anderson puts it, this hopeful stance toward meliorism permeated “Dewey’s faith in [End Page 81] education, and James’ faith in the human spirit” (Philosophy Americana 29). The idea of growth and continual improvement holds intuitive promise, but requires a foundational approach in terms of what it means for teachers and students. For example, as educators, we need clarity around our intended aims in the classroom. In his book, Experience and Education, Dewey provides a partial answer, with attention to the student experience: the “good aim... [forms] a tentative plan of treatment, keeps the plan constantly in view and yet modifies it as conditions develop. The aim, in short, is experimental, and hence constantly growing as it is tested in action” (Dewey 105).While growth and a belief in meliorism involve a sense of gradual improvement and sense of progress, it is clear that growth, especially, is not always a linear process. Marathon runners provide a clear example here. In their training regimens, the goal is to successfully finish a 26.2 mile race, perhaps within a pre-determined time. To meet the designated fitness levels required to run for this distance, it is quite typical for runners to follow twelve- or sixteen- or eighteen-week training programs. These programs provide the runners with a plan to gradually increase endurance capacity, in other words, to grow in physiological and psychological health. While these plans gradually increase the mileage per week, they are not merely linear in nature. Rather, after incremental increases in weekly mileage—say from 28 to 30 to 32 miles per week, it is recommended that the runner then follow with a “step back” or “rest” week, perhaps at 25 miles per week. In this way, the body has an opportunity to restore, thus allowing the runner to continue with this growth pattern and increased fitness the following week.In addition to meliorism, Henry David Thoreau articulated another theme related to pedagogy. Reflecting on his time at Walden Pond, he observed, “how easily and insensibly we fall into a particular route, and make a beaten track for ourselves” (Thoreau, Portable Thoreau 459). Too often, tradition and conformity serve as barriers to growth and meliorism; this impacts teachers and students, and classes may become repetitive, stale, and boring. Examples of conformity occur in the sense of choosing class texts or rigidly adhering to lesson or curricular plans that someone else created. Part of the job of educators is to balance this tendency... (shrink)

With an eye on the future of global ethics, I argue that social-media technologies are not morally neutral tools but are, for all intents and purposes, a kind of agent. They nudge us to do things that are bad for us. Moreover, I argue that we have a duty to quit using social-media platforms, not just on account of possible duties to preserve our own well-being but because users are akin to test subjects on whom developers are testing new nudges, (...) and we ought to deprive them of their test subjects.
