We present a formal system, E, which provides a faithful model of the proofs in Euclid's Elements, including the use of diagrammatic reasoning.

We analyze the pointwise convergence of a sequence of computable elements of L1 in terms of algorithmic randomness. We consider two ways of expressing the dominated convergence theorem and show that, over the base theory RCA0, each is equivalent to the assertion that every Gδ subset of Cantor space with positive measure has an element. This last statement is, in turn, equivalent to weak weak Königʼs lemma relativized to the Turing jump of any set. It is also equivalent to the (...) conjunction of the statement asserting the existence of a 2-random relative to any given set and the principle of Σ2 collection. (shrink)

Man's thought is greatly affected by his experiences in life. A person is a subject who lives alongside different objects and he grows and develops as he interacts with these objects that are around him. Man's fulfillment is something which requires an active interaction with the world because it is through his interaction with the world that he is called upon to perform specific actions which inevitably form him as a person.

The dominated convergence theorem implies that if is a sequence of functions on a probability space taking values in the interval [0, 1], and converges pointwise a.e., then converges to the integral of the pointwise limit. Tao [26] has proved a quantitative version of this theorem: given a uniform bound on the rates of metastable convergence in the hypothesis, there is a bound on the rate of metastable convergence in the conclusion that is independent of the sequence and the underlying (...) space. We prove a slight strengthening of Tao’s theorem which, moreover, provides an explicit description of the second bound in terms of the first. Specifically, we show that when the first bound is given by a continuous functional, the bound in the conclusion can be computed by a recursion along the tree of unsecured sequences. We also establish a quantitative version of Egorov’s theorem, and introduce a new mode of convergence related to these notions. (shrink)

This article describes some potential uses of Bayesian estimation for time-series and panel data models by incorporating information from prior probabilities in addition to observed data. Drawing on econometrics and other literatures we illustrate the use of informative “shrinkage” or “small variance” priors while extending prior work on the general cross-lagged panel model. Using a panel dataset of national income and subjective well-being we describe three key benefits of these priors. First, they shrink parameter estimates toward zero or toward each (...) other for time-varying parameters, which lends additional support for an income → SWB effect that is not supported with maximum likelihood. This is useful because, second, these priors increase model parsimony and the stability of estimates and thus improve out-of-sample predictions and interpretability, which means estimated effect should also be more trustworthy than under ML. Third, these priors allow estimating otherwise under-identified models under ML, allowing higher-order lagged effects and time-varying parameters that are otherwise impossible to estimate using observed data alone. In conclusion we note some of the responsibilities that come with the use of priors which, departing from typical commentaries on their scientific applications, we describe as involving reflection on how best to apply modeling tools to address matters of worldly concern.

Background: When adolescent boys experience close, secure relationships with their parents and peers, the implications are potentially far reaching, including lower levels of mental health problems in adolescence and young adulthood. Here we use rare prospective intergenerational data to extend our understanding of the impact of adolescent attachments on subsequent postpartum mental health problems in early fatherhood.Methods: At age 17–18 years, we used an abbreviated Inventory of Parent and Peer Attachment to assess trust, communication, and alienation reported by 270 male (...) participants in their relationships with mothers, fathers, and peers. More than a decade later, we assessed the adult males, now fathers, at 12 months postpartum for symptoms of depression, anxiety, and stress. Logistic regression was used to examine the extent to which attachment dimensions predicted paternal postpartum mental health, adjusting for potential confounding, and with assessment for interactions between parent and peer attachments.Results: Trust in mothers and peers, and good communication with fathers during adolescence, were associated with 5 to 7 percentage point reductions in postpartum mental health symptoms in early fatherhood. Weak evidence of parent-peer interactions suggested secure attachments with either parent or peer may compensate for an insecure attachment with the other.Conclusions: Our results suggest that fostering trust and communication in relationships that adolescent boys have with parents and peers may have substantial effects on rates of paternal postpartum mental health problems. The protective benefits may be preventative in intergenerational cycles of risk for mental health problems. (shrink)

In 1976, Edward L. Robertson was part of a panel that discussed the overarching topic of Computers in Developing Nations. At the time, computers were slowly being introduced into mainstream society and thoughts of access or even use was the focus of many discussions. Today, not only has computers and its associated technology evolved but so too has the descriptor "developing nations". Since 1976, computers have moved from being desktops, to being portable and hand-held, thus becoming extremely accessible to (...) the general public. In the same vein, the classification of a country's development has since been modified to include another category --- the emerging market. This newly defined category delineates nations that have rapidly growing societies or business markets from those that are still slowly growing. The participants' contributing to this article are all from countries that are identified by the International Monetary Fund as being either an emerging market or a developing country. Another Non-Governmental Organization, the World Bank only recognizes Oman as being a developed country. To follow the [previous] panels' discussion on the importance of computers in developing nations some questions were revisited and new ones were introduced to provide an up-to-date view of computers as seen by specific countries.

Researchers misunderstand their role in creating ethical problems when they allow dogmas to purportedly divorce scientists and scientific practices from the values that they embody. Cortina, Edwards, and Powell help us clarify and further develop our position by responding to our critique of, and alternatives to, this misleading separation. In this rebuttal, we explore how the desire to achieve the separation of facts and values is unscientific on the very terms endorsed by its advocates—this separation is refuted by empirical observation. (...) We show that positivists like Cortina and Edwards offer no rigorous theoretical or empirical justifications to substantiate their claims, let alone critique ours. Following Powell, we point to how classical pragmatism understands ‘purpose’ in scientific pursuits while also providing an alternative to the dogmas of positivism and related philosophical positions. In place of dogmatic, unscientific cries about an abstract and therefore always-unobservable ‘reality,’ we invite all organizational scholars to join us in shifting the discussion about quantitative research towards empirically grounded scientific inquiry. This makes the ethics of actual people and their practices central to quantitative research, including the thoughts, discourses, and behaviors of researchers who are always in particular places doing particular things. We propose that quantitative researchers can thus start to think about their research practices as a kind of work, rather than having the status of a kind of dogma. We conclude with some implications that this has for future research and education, including the relevance of research and research methods. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Paul Oskar Kristeller 1905–1999Edward P. MahoneyPaul Oskar Kristeller was without doubt one of the most productive and accomplished scholars of this century. He received an excellent education in the classics at the Mommsen-Gymnasium in his native Berlin before going to the University of Heidelberg in 1923. There he pursued studies in a wide range of subjects, including medieval history, German literature, physics, and art history. The philosophy professors who (...) much influenced him both at Heidelberg and at Freiburg and Marburg were Ernst Hoffman, Karl Jaspers, Richard Kroner, and Martin Heidegger. In 1929 he received his doctorate from Heidelberg for his dissertation Der Begriff der Seele in der Ethik des Plotin, which was directed by Hoffman and published at Tübingen the same year. He then went to Berlin, where he engaged in formal studies in classical philology before going to Freiburg to do postgraduate work in philosophy with Heidegger during the years 1931 to 1933. Heidegger approved a study of Marsilio Ficino as Kristeller’s Habili-tationschrift and helped him to secure a fellowship enabling him to do research on Ficino and to begin writing. After visiting Italy during this period and taking into account the changed political scene in Germany, Kristeller decided in 1934 to move to Italy permanently. He taught in Florence in a high school for German Jewish students until he secured in 1935, with the help of Giovanni Gentile, a lectureship in German at the Scuola Superiore and the University of Pisa. He maintained throughout his academic career a personal and warm attachment to the Scuola Superiore. Moreover, he enjoyed throughout his subsequent career a warm and personal friendship with various Italian scholars that was first developed during his Italian stay in the thirties.While still in Italy, Kristeller completed his book on Ficino in 1937; he prepared an Italian version the next year. However, both the German and Italian versions would be published only years later. During this period he also engaged in manuscript studies in the major Italian cities, searching in particular for Ficino manuscripts. The result of these labors was his two-volume work, Supplementum Ficinianum: Marsilii Ficini Philosophi Platonici Opuscula Inedita et Dispersa, which was published by the Scuola Normale in 1937. He considered his “teachers” in manuscript studies to be Giovanni Cardinal Mercati, Monsignor Auguste Pelzer, and Ludwig Bertalot. Giovanni Gentile aided the publication of Kristeller’s Supplementum Ficinianum and subsequently helped him to emigrate to the United States. Kristeller always maintained a loyalty to Gentile and felt gratitude to him for extending him such help.In 1938 Kristeller lost his position at Pisa because of the Fascist anti-Semitic laws, but he was permitted to go to Rome where he assisted Bertalot in manuscript research at the Vatican library. Through the intervention of Roland H. Bainton, Dean P. Lockwood, Dom Anselm Strittmater, O.S.B., and other American [End Page 758] friends Kristeller was able to leave for the United States. He arrived at New York in February 1939 and spent the Spring term at Yale University. He was given an adjunct position at Columbia University for the fall term, holding the rank of Associate until 1948, when he was made an Associate Professor of Philosophy. By that time he had established himself as a major force in the development of Renaissance studies in the United States. His book on Ficino was translated into English as The Philosophy of Marsilio Ficino and published in 1943 by the Columbia University Press. The Italian version was published at Florence in 1953; a revised edition, containing a new bibliography that had been brought up to date, appeared in 1988.Kristeller published a large number of articles on a wide range of topics, establishing himself as a major interpreter of the significance of Renaissance humanism as well as a leading authority not only on Ficino and Renaissance Platonism but also on Pietro Pomponazzi and Renaissance Aristotelianism. He developed at Columbia bonds of friendship with Ernest A. Moody and John Herman Randall, Jr., both of whom had strong interests in late-medieval Aristotelianism. With Randall and Ernst Cassirer he prepared what would become a bestseller, the Renaissance Philosophy of Man: Selections... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Martin Luther King, Jr., and the Legacy of Boston PersonalismJ. Edward Hackett1. IntroductionWhen the question of the Rev. Dr. Martin Luther King, Jr.’s philosophical legacy arises in the academy, so far, the question remains open-ended (though, as I will shortly argue, the question has already been answered by King himself). Beyond his presence in public American consciousness, King left behind speeches, sermons, correspondence, and writings that inspire both (...) philosophical and theological reflection. However, King is also interpreted on the merits of the biases and philosophical traditions that we scholars navigate. Such biases and philosophical traditions mediate our experience of encountering King, and this mediation can impact our understanding of what exactly King’s philosophical legacy is.1Accordingly, we should seek to reconstruct King’s thoughts in the philosophical vocabulary King employed rather than displacing King from his own agency and the contexts that shaped him.2 In doing so, we prevent mistakes and misunderstandings that plague the public knowledge of King’s legacy. And yet, serious misunderstanding occurs every January with light fluff pieces in major newspapers and websites from authors who do not read King’s corpus. What’s more, some scholars are guilty of this lack of reading King widely. Consider Martha Nussbaum and her glaring error and omission in her recent contribution to a recent book that purports to look at King as a philosopher: “Although a religious man, [King] did not advance in his political writings a comprehensive and religious doctrine, as Gandhi did” (Nussbaum 123). In an otherwise interesting article about political emotions, Nussbaum completely neglects any historical consideration or development where King describes himself as a personalist.3 Like others, Nussbaum disregards King’s own self-description. This disregard is tantamount to a silent [End Page 45] and implicit racism that results in scholarly efforts that deprive King of his own intellectual agency when interpreting his work. This tendency prevails in both philosophy and theology departments, and this neglect has also been the larger challenge of African American philosophy gaining more acceptance as a field of philosophical inquiry (McClendon and Ferguson 38). My efforts in this article are to put an end to continual misreadings of King. First and foremost, King is a personalist.While this essay defends the personalist interpretation of King, let me lay out briefly those pieces of evidence. The interpretation of King as a personalist rests on four evidential sources: (1) King’s own words, (2) family background, (3) influence of personalist ideas on his writings, and (4) the tradition of King’s reception by other Boston personalists. First, King describes himself in his own words as a personalist. This is perhaps the biggest piece of evidence for why we should read King as a personalist. Second, King was influenced by personalism before studying Brightman’s philosophy with Gregory Davis at Crozers Theological Seminary.4 Before Morehouse College and Crozers Theological Seminary, according to Rufus Burrow, homespun personalism emerges out of King’s upbringing within the Black Church. For this reason, scholars should not doubt that King synthesizes personalist influences with how he was raised (Burrow, God and Human Dignity 17–31). Moreover, given that King chose to go to Boston University to study with Brightman and to be where Boston personalism was known to be strong, all of these facts indicate that King was a personalist (Burrow, God and Human Dignity 24).Homespun personalism gave King a vocabulary to bring together and synthesize many intellectual forces in his life, and this synthesis is recognized by other personalists. Walter Muelder is one such personalist. Muelder was Dean of Boston University’s School of Theology from 1945–1972 when King attended. Muelder and King exchanged correspondence, and Muelder delivered many lectures, some published and others unpublished, on the personalism of King. The most famous of these lectures is one Muelder gave to Morehouse College in 1983, in which Brightman’s moral law system is read into King’s own words. Taking this historical background and also that, to this day, some teachers at Morehouse College, like Lawrence Carter, make their students learn the personalist moral law system from Muelder and Bright-man, the personalist interpretation...

In lieu of an abstract, here is a brief excerpt of the content:EDWARD W. STRONG, 1901--1990 Edward W. Strong, one.of the founders and leaders of the Journal of the HistoryofPhilosophy,passed away on January 13, 199o, after a long struggle with cancer. Born in Dallas, Oregon in 19~ 1, he was eighty-eight years old when he died. He did his undergraduate studies at Stanford, receiving his B.A. in 1925. Then he went on to graduate studies at Columbia, where he (...) received a master's degree in 1927 and a Ph.D. in 1937. He taught at City College in New York from 1927 to 1932, and then began his long career at the University of California, Berkeley, where he remained for the rest of his academic life. During World War II, he became laboratory manager of the university's Radiation Laboratory (now called the Lawrence Berkeley Laboratory), which was part of the Manhattan Project to develop the atomic bomb. After the war, Strong became a full professor in 1947, chairman of the Sociology Department from 1946 to 1952, Associate Dean of the College of Letters and Sciences from 1947 to 1955, a leader of the Academic Senate and its Educational Policy Committee, and Chancellor of the Berkeley campus from 1961 to 1965.This was a period of very rapid growth for the campus as well as its most troubled time. When the student rebellion--the Free Speech Movement--broke out, Strong tried valiantly but unsuccessfully to preserve those academic values he felt most challenged. As the conflict wore on, he ceased to have the full support of his superiors, the President of the Universityand the Board of Regents, who negotiated a resolution with the students, the effects of which are still being felt at Berkeley and elsewhere in the United States. Some feel that Strong's position in the struggle that transformed American universities has not been properly understood, and that his role has been portrayed unfairly to enhance that of his superiors. In any event, he resigned as Chancellor and became Professor Emeritus in 1967. Strong developed his interest in the history of philosophy, history of science, and history of ideas at Columbia during its heyday as a center for such concerns, under the leadership of John Dewey and Frederick Woodbridge. He told me that he was also very much influenced by the historical interests of Morris Raphael Cohen, his senior colleague at City College. His dissertation, Proceduresand Methods,was, and still is, a basic study of the origin and development of modern science. (It was mentioned approvingly in an article by Ernst [9] 10 JOURNAL OF THE HISTORY OF PHILOSOPHY 29:1 JANUARY 1991 Cassirer, in 194o). In contrast to E. A. Burtt, whose MetaphysicalFoundationsof ModernPhysicalSciencestressed the philosophical and theological concerns of the early scientists, Strong emphasized the practical engineering concerns that were involved at the time. This led him to studies of Kepler, Galileo, and Newton, as well as to the scientific views of medieval thinkers, and modern views in the philosophy of science. Philosophically he was a naturalist, continuing the Columbia tradition. He was also very interested in Bergson's views, especially as they related to modern scientific ideas. He was the inspirer and founder of the History of Science discussion group at Berkeley, which became an important forum for creative research in this area. Strong was President of the American Philosophical Association in 1959. Because of the limited attention and concern given to the history of philosophy in most of the then-existing philosophicaljournals in America, the American Philosophical Association in 1957 approved in principle the establishment of a journal devoted to the history of philosophy, and appointed a committee of six members--Paul Kristeller, Gregory Vlastos, Richard McKeon, Julius Weinberg, John Goheen, and Edward Strong--to explore "ways and means to this end." Since all American philosophical journals at that time were published in the East and Midwest, Strong and Goheen were encouraged to try to establish the journal in the West. Strong has detailed the efforts to do this in his article, "The Founding of theJournal oftheHistoryofPhilosophy,"Journalof theHistoryofPhilosophy~5 (1987): 179-83. I first met Ed Strong at Trinity College, Dublin, in the summer of 1953, when I was a... (shrink)

Property dualism is enjoying a slight resurgence in popularity, these days; substance dualism, not so much. But it is not as easy as one might think to be a property dualist and a substance materialist. The reasons for being a property dualist support the idea that some phenomenal properties (or qualia) are as fundamental as the most basic physical properties; but what material objects could be the bearers of the qualia? If even some qualia require an adverbial construal (if they (...) are modifications of the thing that is conscious because of them, not properties of something else to which the subject of consciousness is related), then the property dualist can be driven to speculative forms of materialism none of which, at this point, looks more likely to be true than the more modest versions of emergent dualism defended by contemporary substance dualists.

"I am delighted to offer my highest praise to Dean Cocking and Jeroen van den Hoven's brilliant new book, Evil Online. The confrontation between good and evil occupies a central place in the challenges facing our human nature, and this creative investigation into the spread of evil by means of all-powerful new technologies raises fundamental questions about our morality and values. Cocking and Van den Hoven's account of the moral fog of evil forces us to face both the demons (...) within each of us as well as the demons all around us. In the end, we are all enriched by their perceptive analyses." —Phil Zimbardo, Professor Emeritus of Psychology, Stanford University Principal Investigator, Stanford Prison Experiment "The internet offers new and deeply concerning opportunities for immorality, much of it shocking and extreme. This volume explains with great insight and clarity the corrupting nature of the internet and the moral confusion it has produced. It will play a vital role in the growing debate about how to balance the benefits of the internet against the risks it poses to all of us. Evil Online is an excellent book." —Roger Crisp, Professor of Moral Philosophy, University of Oxford We now live in an era defined by the ubiquity of the internet. From our everyday engagement with social media to trolls on forums and the emergence of the dark web, the internet is a space characterized by unreality, isolation, anonymity, objectification, and rampant self-obsession—the perfect breeding ground for new, unprecedented manifestations of evil. Evil Online is the first comprehensive analysis of evil and moral character in relation to our increasingly online lives. Chapters consider traditional ideas around the phenomenon of evil in moral philosophy and explore how the dawn of the internet has presented unprecedented challenges to older theoretical approaches. Cocking and Van den Hoven propose that a growing sense of moral confusion—moral fog—pushes otherwise ordinary, normal people toward evildoing, and that values basic to moral life such as autonomy, intimacy, trust, and privacy are put at risk by online platforms and new technologies. This new theory of evildoing offers fresh insight into the moral character of the individual, and opens the way for a burgeoning new area of social thought. A comprehensive analysis of an emerging and disturbing social phenomenon, Evil Online examines the morally troubling aspects of the internet in our society. Written not only for academics in the fields of philosophy, psychology, information science, and social science, Evil Online is accessible and compelling reading for anyone interested in understanding the emergence of evil in our digitally-dominated world.

The ‘friends of temporal parts’ and their opponents disagree about how things persist through time. The former, who hold what is sometimes called a ‘4D’ theory of persistence, typically claim that all objects that last for any period of time are spread out through time in the same way that spatially extended objects are spread out through space — a different part for each region that the object fills. David Lewis calls this manner of persisting ‘perdurance’. The opposing, ‘3D’ theory (...) has it that at least some objects do not persist in this manner; they ‘endure’ through time by ‘being wholly present at more than one time’.1 A related dispute pits ‘presentists’ against ‘non-presentists’. Presentists hold that the only things that really exist are those that exist now, at the present moment; and nonpresentists believe in something like a ‘block-universe’ in which non-simultaneous objects and events nevertheless co-exist (in a tenseless or non-temporal sense). Of late, the relations between these four positions have come under considerable scrutiny.2 As Ned Markosian has pointed out, it would be surprising if commitment to a perdurance or endurance theory of persistence automatically foreclosed one’s options in the presentism—non-presentism debate. But, says Markosian, that is just what the standard formulations of the perdurance and endurance theories imply.3 David Lewis has set the terms of the debate; in his usage, someone who thinks that all persisting objects endure would be said to hold the following.

We cannot escape Indiana Jones! (Not that we would want to, of course.) Harrison Ford deserves credit for the character's popularity. His ability to subtly play up Indy's foibles while playing down the character's heroism, makes Indiana Jones relatable. Of course, Lucas and the screenwriters are also responsible, as they magnificently depict Indy battling antagonists seeking to possess mystical objects for world domination. But Indy is no mere action hero. He also struggles with unrequited love that lingers for decades, an (...) estrangement from his over-bearing father that lasts just as long, and a life-long obsession with regaining an important object unfairly taken from him. As we know, Indy doesn't always choose wisely, and if the Young Indiana Jones Chronicles are to be trusted, he made many missteps in his youth on the way to becoming the hero we know and love. Indy loses a fight as often as he wins, and when he wins, he doesn't always fight fairly. In fact, he stumbles so often, one might wonder why he persists decade after decade toward his goals. He's not getting any younger. What's the point? And, as he inexplicably trudges on, he-in the four films and various graphic novels-has many alleged encounters with the supernatural. He's not a religious person (at all), so what should he make of those? Should he take the leap of faith and become a believer? While we often see him conducting his highly unconventional fieldwork, spending an unusual amount of time in caves, he cannot completely ignore his "day job" teaching undergraduates and aiding their pursuit of knowledge. But why should archaeologists strive to put artifacts in a museum, or search for "fact," but not "truth" (and who is Dr. Tyree, anyway)? The Indiana Jones character is expressive of the human condition, vividly illuminating our struggles and issues on the big screen. True, we don't have John Williams's orchestra filling us with pride when we manage to do the right thing or play the part of the hero. Still, no one would blame you if you imagined Indy's theme blaring in the background while rising to meet a challenge! (shrink)

Researchers often lack the necessary data to credibly estimate racial discrimination in policing. In particular, police administrative records lack information on civilians police observe but do not investigate. In this article, we show that if police racially discriminate when choosing whom to investigate, analyses using administrative records to estimate racial discrimination in police behavior are statistically biased, and many quantities of interest are unidentified—even among investigated individuals—absent strong and untestable assumptions. Using principal stratification in a causal mediation framework, we derive (...) the exact form of the statistical bias that results from traditional estimation. We develop a bias-correction procedure and nonparametric sharp bounds for race effects, replicate published findings, and show the traditional estimator can severely underestimate levels of racially biased policing or mask discrimination entirely. We conclude by outlining a general and feasible design for future studies that is robust to this inferential snare. (shrink)

During its forty year lifespan, string theory has always had the power to divide, being called both a 'theory of everything' and a 'theory of nothing'. Critics have even questioned whether it qualifies as a scientific theory at all. This book adopts an objective stance, standing back from the question of the truth or falsity of string theory and instead focusing on how it came to be and how it came to occupy its present position in physics. An unexpectedly rich (...) history is revealed, with deep connections to our most well-established physical theories. Fully self-contained and written in a lively fashion, the book will appeal to a wide variety of readers from novice to specialist. (shrink)

Traditional social worlds enable plural modes of self‐expression and communication across both public and private realms. Our identity involves a variety of aspects of self. Moreover, plural and conflicting aspects of self are often presented within the context of one relationship, role, or encounter. The presentation of less chosen aspects of our selves often also provides the object for the expression of certain relational aspects of respect for one another's privacy. Self‐presentation and shared activity in many online social worlds can (...) also enable autonomy and privacy. The online revolutions in access to information and to one another have provided unprecedented opportunities to expand our knowledge, to pursue our social and working lives, and to carry on all sorts of interests and activities. One specific example of how some of our fears about online evils have been claimed to be exaggerated and misguided concerns fears of risks to our children from online sexual predators. (shrink)

In Morality and Ethics of War, which includes a foreword by Major General Susan Coyle, ethicist Deane-Peter Baker goes beyond existing treatments of military ethics to address a fundamental problem: the yawning gap that exists between the diverse moral frameworks defining personal identity in a multicultural society on the one hand, and the professional military ethic on the other. Baker argues that overcoming this chasm is essential to minimising the ethical risks that can lead to operational and strategic failure for (...) military forces engaged in today's complex conflict environment. He contends that spanning the gap is vital in preventing moral injury from befalling the nation's uniformed servants. Drawing on a revised account of what he calls 'the Just War Continuum', Baker develops a bridging framework that combines conceptual clarity and rigour with insights from cutting edge psychological research and creates a practical means for military leaders to negotiate the moral chasm in military affairs.

This book offers the first introduction to a major Japanese philosophical movement through the interests and arguments of its founder, Nishida Kitaro (1870-1945), his successor, Tanabe Hajime (1885-1962), and student-turned-critic, Tosaka Jun (1900-1945). Focusing on their contributions to thinking about place, space, and dialectics, this concise introduction brings these influential thinkers to life by connecting their work to issues still debated in the philosophy of science and physics today. Beginning with an overview of the reception of quantum physics and relativity (...) theory in Japan and concluding with an account of the direct relevance of the Kyoto School to the development of world philosophy in a posthuman age, each clearly-written chapter engages historical contexts and includes: · Carefully-chosen excerpts and original translations of Nishida, Tanabe, and Tosaka · Focus boxes explaining complex concepts and problems of contextualization. A timeline, glossary and index. Further reading lists featuring relevant and significant articles and books in English. This introduction is an ideal starting point for students and lecturers looking to become better acquainted with three central Japanese philosophers and learn why their work impacts our current thinking about science.

Computational complexity theory is a subfield of computer science originating in computability theory and the study of algorithms for solving practical mathematical problems. Amongst its aims is classifying problems by their degree of difficulty — i.e., how hard they are to solve computationally.

Hegel's Philosophy of Right was his last systematic work and the most complete statement of his mature views on ethical and political philosophy. It explores the relationships between three distinct conceptions of human freedom: persons as possessing contract rights, subjects as reflective moral agents, and individuals as members of an ethical community. It strongly influenced the early Marx and with the rise of debates over liberalism and communitarianism in the latter half of the twentieth century. In this volume an outstanding (...) line up of contributors examine the nature and impact of Hegel's Philosophy of Right. A diverse array of topics is examined, ranging from Hegel's account of rights, freedom, the state and history to some hitherto relatively overlooked topics such as Hegel and Luther, art and nationality and Hegel and the market. Hegel's Philosophy of Right: Critical Perspectives on Freedom and History will be valuable reading for scholars of Hegel, nineteenth-century German philosophy, political philosophy and history of political thought.

How can I give you a reason to believe what I tell you? I can influence the evidence available to you. Or I can simply invite your trust. These two ways of giving reasons work very differently. When a speaker tells her hearer that p, I argue, she intends that he gain access to a prima facie reason to believe that p that derives not from evidence but from his mere understanding of her act. Unlike mere assertions, acts of telling (...) give reasons directly. They give reasons by inviting the hearer’s trust. This yields a novel form of anti-reductionism in the epistemology of testimony. The status of testimony as a sui generis source of epistemic warrant is entailed by the nature of the act of telling. We can discover the nature of this illocution, and its epistemic role, by examining how it functions in the real world of human relations. (shrink)

One fateful day in May 1975, Foucault dropped acid in the southern California desert.

That trip helped redirect Foucault's thought and contributed to a tectonic shift in the intellectual (...) life of the era. He came to reinterpret the social movements of May '68 and reposition himself politically in France, embracing anti-totalitarian currents and becoming a critic of the welfare state. Mitchell Dean and Daniel Zamora examine the full historical context of the turn in Foucault's thought, which included studies of the Iranian revolution and French socialist politics, through which he would come to appreciate the possibilities of autonomy offered by a new force on the French political scene that was neither of the left nor the right: neoliberalism.

The paper unpacks the far-reaching theoretical and practical issues that underlay the classical debate between cognitive psychologist Ulric Neisser and discursive social psychologists Derek Edwards and Jonathan Potter on Watergate witness John Dean's memory. Accounting for their disagreements, Neisser claimed the mantle of the cognitive-ecological approach to memory and emphasized the psychologist's ultimate priority of truth over discourse, while Edwards and Potter claimed that of discursive/rhetorical psychology and focused exclusively on discourse over truth. As such, the debate at the (...) time ended in mutual misunderstanding and the shadow of theoretical incommensurability. However, a rhetorical analysis of the arguments suggests that Neisser was right about truth when he intuitively sensed the importance of discourse, and Edwards and Potter were right about discourse when they did not lose sight of truth. Therefore, beyond the impasse there has remained a promise inherent in the debate: it demonstrated an imaginative attempt to undermine the absolute dichotomy of truth and rhetoric and demonstrate their mutual inter-dependence. As will be argued, such integration of traditional concerns of the psychologist entails the re-conceptualization of the discipline as political and moral science. (shrink)

[The version of this paper published by Oxford online in 2019 was not copy-edited and has some sense-obscuring typos. I have posted a corrected (but not the final published) version on this site. The version published in print in 2020 has these corrections.] Which is more fundamental, assertion or testimony? Should we understand assertion as basic, treating testimony as what you get when you add an interpersonal addressee? Or should we understand testimony as basic, treating mere assertion -- assertion without (...) testimony -- as what you get when you subtract that interpersonal relation? In this chapter, I’ll argue for the subtractive approach and for the more general thesis that its treatment of the interpersonal element in assertion makes understanding that interpersonal element the key to understanding how assertion expresses belief. My theory of belief-expression in assertion treats it as internalizing the transmission of belief in testimony. How we understand that internalizing move depends on how we conceptualize the interpersonal element in testimony. Since what I’ll call the Command Model does not give us the conceptual resources to make this move, we should adopt an alternative that I’ll call the Custodial Model, on which a testifier aims not to convince her addressee but to reason with him – to give him reasons to believe what she tells him grounded in her trustworthiness in thus attempting to influence him. The subtractive approach to assertion thus rests on a key distinction between the aims of reasoning and persuasion. (shrink)

An assurance theory of trust begins from the act of assurance – whether testimonial, advisorial or promissory – and explains trust as a cognate stance of resting assured. My version emphasizes the risks and rewards of trust. On trust’s rewards, I show how an assurance can give a reason to the addressee through a twofold exercise of ‘normative powers’: (i) the speaker thereby incurs an obligation to be sincere; (ii) if the speaker is trustworthy, she thereby gives her addressee the (...) reason. Each claim is controversial; my contribution lies in how I defend them together, linking the sincerity obligation to the provision of reasons. On trust’s risks, I defend a popular thesis about the nature of trust – that trust differs from mere reliance in how it risks betrayal – against the objection that the thesis ‘moralizes’ trust. Such betrayal need not be moral, I argue, because it may derive entirely from how the assurance purports to provide a reason. (shrink)

Cornelia Dean draws on her 30 years as a science journalist with the New York Times to expose the flawed reasoning and knowledge gaps that handicap readers when they try to make sense of science. She calls attention to conflicts of interest in research and the price society pays when science journalism declines and funding dries up.--.

This study provides an evaluation of ethical business perception of busIness students from three countries: Australia, Taiwan and the United States. Although statistically significant differences do exist there is significant agreement with the way students perceive ethical/unethical practices in business. The findings of this paper indicate a universality of business ethical perceptions.

The biggest obstacle to understanding Aquinas's account of the soul may be the word “soul”. On hearing it, many people are prone to think of ghosts, ectoplasm, or Rene Descartes's notion of res cogitans. None of these has anything to do with the soul as Aquinas understands it. But even the standard one‐line Aristotelian‐Thomistic characterization of the soul as the form of the living body can too easily mislead. As is well known, the word “soul” is in Aristotelian‐Thomistic philosophy essentially (...) a technical term for the substantial form of a living thing. Material substances can be destroyed by other natural objects because they do have an inherent tendency toward corruption. A human being is the kind of substance which, in its mature and normal state, exhibits both the properties and causal powers characteristic of animality and those characteristic of rationality.

In the famous Correspondence with Clarke, which took place during the last year of Leibniz's life, Leibniz advanced several arguments purporting to refute the absolute theory of space and time that was held by Newton and his followers. The main aim of this book is to reassess Leibniz's attack on the Newtonian theory in so far as he relied on the principle of the identity of indiscernibles. The theological side of the controversy is not ignored but isolated and discussed in (...) the last three chapters, which deal with problems connected with the notions of omnipotence and omniscience.
