By analyzing a gedanken experiment designed to measure the distance l between two spatially separated points, we find that this distance cannot be measured with uncertainty less than (ll 2 P) 1/3 , considerably larger than the Planck scale lP (or the string scale in string theories), the conventional-wisdom uncertainty in distance measurements. This limitation to space-time measurements is interpreted as resulting from quantum fluctuations of space-time itself. Thus, at very short distance scales, space-time is “foamy.” This intrinsic foaminess of (...) space-time provides another source of noise in the interferometers. The LIGO/VIRGO and LISA generations of gravity-wave interferometers, through future refinements, are expected to reach displacement noise levels low enough to test our proposed degree of foaminess in the structure of space-time.

John Buridan was the most famous philosophy teacher of his time, and probably the most influential. In this important new book, Jack Zupko offers the first systematic exposition of Buridan's thought to appear in any language. Zupko uses Buridan's own conception of the order and practice of philosophy to depict the most salient features of his thought, beginning with his views on the nature of language and logic and then illustrating their application to a series of topics in metaphysics, natural (...) philosophy, and ethics. Part 1 of John Buridan considers the picture of language and logic developed in Buridan's Summulae de dialectica. Buridan systematically overhauled the logic he first learned and later taught at the University of Paris, redeeming the older tradition of Aristotelian logic in terms, propositions, and arguments. This made possible newer and more powerful forms of philosophical discourse. The second part of this volume provides a reading of Buridan's philosophy, showing how this discourse shaped his treatment of speculative questions such as the relation between soul and body, the nature of knowledge, the proper subject of psychology, the function of the.

Economic theory is built on assumptions about human behavior—assumptions embodied in rational-choice theory. Underlying these assumptions are implicit notions about how we think and learn. These implicit notions are fundamentally important to social explanation. The very plausibility of the explanations that we develop out of rational-choice theory rests crucially on the accuracy of these notions about cognition and rationality. But there is a basic problem: There is often very little relationship between the assumptions that rational-choice theorists make and the way (...) that humans actually act and learn in everyday life. This has significant implications for economic theory and practice. It leads to bad theories and inadequate explanations; it produces bad predictions and, thus, supports ineffective social policies.

Jack Cohen and Ian Stewart explore the ability of complicated rules to generate simple behaviour in nature through 'the collapse of chaos'.

This book offers solutions to two persistent and I believe closely related problems in epistemology. The first problem is that of drawing a principled distinction between perception and inference: what is the difference between seeing that something is the case and merely believing it on the basis of what we do see? The second problem is that of specifying which beliefs are epistemologically basic (i.e., directly, or noninferentially, justified) and which are not. I argue that what makes a belief a (...) perceptual belief, or a basic belief, is not any introspectible feature of the belief but rather the nature of the cognitive system, or "module", that is causally responsible for the belief. Thus, even zombies, who in the philosophical literature lack conscious experiences altogether, can have basic, justified, perceptual beliefs. -/- The theories of perceptual and basic beliefs developed in the monograph are embedded in a larger reliabilist epistemology. I use this theory of basic beliefs to develop a detailed reliabilist theory: Inferentialist Reliabilism, which offers a reliabilist theory of inferential justification and which solves some longstanding problems for other reliabilist views by demanding inferential support for some—but not all—beliefs. The book is an instance of a thoroughgoingly naturalistic approach to epistemology. Many of my arguments have an empirical basis, and the view that I endorse reserves a central role for the cognitive sciences—in particular, cognitive neuroscience—in filling in the details of an applied epistemological theory.

The history of the Frankfurt School cannot be fully told without examining the relationships of Critical Theorists to their Jewish family backgrounds. Jewish matters had significant effects on key figures in the Frankfurt School, including Max Horkheimer, Theodor W. Adorno, Erich Fromm, Leo Lowenthal and Herbert Marcuse. At some points, their Jewish family backgrounds clarify their life paths; at others, these backgrounds help to explain why the leaders of the School stressed the significance of antisemitism. In the post-Second World War (...) era, the differing relationships of Critical Theorists to their Jewish origins illuminate their distinctive stances toward Israel. This book investigates how the Jewish backgrounds of major Critical Theorists, and the ways in which they related to their origins, impacted upon their work, the history of the Frankfurt School, and differences that emerged among them over time.

Introspective evidence is still treated with great suspicion in cognitive science. This work is designed to encourage cognitive scientists to take more account of the subject's unique perspective.

Economists have always recognised that human endeavours are constrained by our limited and uncertain knowledge, but only recently has an accepted theory of uncertainty and information evolved. This theory has turned out to have surprisingly practical applications: for example in analysing stock market returns, in evaluating accident prevention measures, and in assessing patent and copyright laws. This book presents these intellectual advances in readable form for the first time. It unifies many important but partial results into a satisfying single picture, (...) making it clear how the economics of uncertainty and information generalises and extends standard economic analysis. Part One of the volume covers the economics of uncertainty: how each person adapts to a given fixed state of knowledge by making an optimal choice among the immediate 'terminal' actions available. These choices in turn determine the overall market equilibrium reflecting the social distribution of risk bearing. In Part Two, covering the economics of information, the state of knowledge is no longer held fixed. Instead, individuals can to a greater or lesser extent overcome their ignorance by 'informational' actions. The text also addresses at appropriate points many specific topics such as insurance, the Capital Asset Pricing model, auctions, deterrence of entry, and research and invention. (shrink)

In _Phenomenology, Naturalism and Empirical Science_, Jack Reynolds takes the controversial position that phenomenology and naturalism are compatible, and develops a hybrid account of phenomenology and empirical science. Though phenomenology and naturalism are typically understood as philosophically opposed to one another, Reynolds argues that this resistance is based on an understanding of transcendental phenomenology that is ultimately untenable and in need of updating. Phenomenology, as Reynolds reorients it, is compatible with liberal naturalism, as well as with weak forms of methodological (...) naturalism. Chapters explore areas where scientific and phenomenological work overlap and sometimes conflict, contesting standard ways of understanding the relationship between phenomenological philosophy and empirical science. The book outlines the significance of the first-person perspective characteristic of phenomenology—both epistemically and ontologically—while according due respect to the relevant empirical sciences. This book makes a significant contribution to one of the central issues in phenomenology and argues for phenomenology’s ongoing importance for the future of philosophy. (shrink)

An influential argument for anti-reductionism about testimony, due to CAJ Coady, fails, because it assumes that an inductive global defense of testimony would proceed along effectively behaviorist lines. If we take seriously our wealth of non-testimonially justified folk psychological beliefs, the prospects for inductivism and reductionism look much better.

In our wakeful conscious lives, the experience of time and dynamic temporal phenomena—such as continuous motion and change—appears to be ubiquitous. How is it that temporality is woven into our conscious experience? Is it through perceptual experience presenting a series of instantaneous states of the world, which combine together—in a sense which would need to be specified—to give us experience of dynamic temporal phenomena? In this paper, I argue that this is not the case. -/- Several authors have recently proposed (...) dynamic snapshot models of temporal experience— such as Prosser and Arstila, building upon Le Poidevin— according to which perceptual experience has no temporal content of a non‐zero extent. I argue that there is an absence of motivation for such a view; I develop and defend the claim that perceptual experience minimally presents something of some non‐zero temporal extent as such.

In lieu of an abstract, here is a brief excerpt of the content:Rudolf A. Makkreel 1936-2021Jack Zupko, Former Editor, Journal of the History of PhilosophyRudi Makkreel, longtime editor (1983–98) of the Journal of the History of Philosophy and President of its Board of Directors (1998–2018), died October 2021 in Atlanta, GA, of complications from ALS.Rudi was one of the foremost Kant scholars of his generation, helping to bring the Critique of Judgment into the broader currency it enjoys among philosophers today. (...) He also made important contributions to the fields of aesthetics, hermeneutics, and the philosophy of history. His Dilthey, Philosopher of the Human Studies (Princeton, 1975; 2nd edition, 1992), nominated for both a Pulitzer Prize and a National Book Award, introduced the thought of Wilhelm Dilthey to the anglophone world, explaining the significance of Dilthey’s work on the social and cultural dimensions of human experience as well as its influence on early analytic philosophers such as Carnap. With Frithjof Rodi, he completed the six-volume Wilhelm Dilthey: Selected Works (Princeton, 1985–2019), an enduring legacy for students and historians of German philosophy of the late nineteenth and early twentieth centuries.Rudi was born in Antwerp, Belgium in 1939. He immigrated to the United States in 1951 and completed his graduate studies in philosophy at Columbia University in 1966. He taught at the University of California, San Diego until 1973, after which he joined the faculty at Emory University, his academic home as Charles Howard Candler Professor of Philosophy for almost half a century. He was a native Dutch speaker, but equally at home in both English and German, always exemplifying for his students the importance of knowing the original languages of the philosophers one is researching.Rudi was not just a scholar’s scholar but a perceptive critic and outstanding teacher, as his many students in academic positions around the world can attest. As a colleague he was unfailingly supportive, in his gentle and softly spoken way, quietly putting opportunities in the path of younger historians of philosophy. He was committed to ensuring the Emory philosophy program remained solidly grounded in the history of philosophy, with faculty expertise in all of its canonical areas. He was dedicated to his students and to serving the profession through the JHP, guiding the work of its Board of Directors and providing invaluable advice (though only when asked) to later Editors.Rudi took over editorship of the JHP at a tumultuous time in its history; he brought stability to its operations and ensured that the JHP remained a “big tent” in the field, publishing research on all figures, movements, and periods in the history of western philosophy, by scholars with a variety of philosophical styles and research methods. This meant making room for original papers on understudied figures and topics, despite the pressure to publish the best work on better-known figures and more traditional or popular topics, with which he could have easily filled each issue.He leaves behind his wife, Frances, a daughter, Karen, and a grandchild, as well as many former students and colleagues, who miss his gentle demeanor, wry sense of humor, and penetrating intellect.Jack Zupko, Former Editor, Journal of the History of PhilosophyUniversity of AlbertaCopyright © 2023 Journal of the History of Philosophy, Inc....

Open-mindedness is generally regarded as an intellectual virtue because its exercise reliably leads to truth. However, some theorists have argued that open-mindedness’s truth-conduciveness is highly contingent, pointing out that it is either not truth-conducive at all under certain scenarios or no better than dogmatism or credulity in others. Given such shaky ties to truth, it would appear that the status of open-mindedness as an intellectual virtue is in jeopardy. In this paper, I propose to defend open-mindedness against these challenges. In (...) particular, I show that the challenges are ill-founded because they misconstrue the nature of open-mindedness and fail to consider the requisite conditions of its application. With a proper understanding of open-mindedness and of its requirements, it is clear that recourse to it is indeed truth-conducive. (shrink)

This paper develops a form of moral actualism that can explain the procreative asymmetry. Along the way, it defends and explains the attractive asymmetry: the claim that although an impermissible option can be self-conditionally permissible, a permissible option cannot be self-conditionally impermissible.

The importance of writing as a means of communication in a society formerly without it, or where writing has been confined to particular groups, is enormous. It objectifies speech, provides language with a material correlative, and in this material form speech can be transmitted over space and preserved over time. In this book the contributors discuss cultures at different levels of sophistication and literacy and examine the importance of writing on the development of these societies. All the articles except the (...) first were specially written for this book and the extensive introduction unites and synthesizes the material. (shrink)

2 no predictions or experimental findings based on the Identity Theory differ from those based on mind-brain Parallelism or Epiphenomenal ism, i.e., Dualism in general. The Identity Theory, therefore, must stand or fall on its reputed conceptual advantages over Dualism. Then the conceptual issues at stake in the mind-brain problem are discussed. The kernel of truth present in the Identity Theory is shown to be obscured by all the talk about reducing sensations to neural processes. An attempt is made to (...) characterize pain adequately as a pattern or complex of bodily processes. This view is then reconciled with the asymmetry in the way one is aware of one's own pains and the way in which others are. This asymmetry constitutes an epistemological dualism which no philosophical theory or scientific experiment could alter. The sense in which experiences are both mental and physical is thus elucidated. A Multi-Aspect Theory of the mind is presented and defended. Five aspects of pain are discussed in some detail: experiential, neural, bodily, behavioral and verbal. Having a mind characteristically involves having all of these features except the bodily (i.e., a physical irregularity). Thus having a mind characteristically entails having experiences and a healthy, functioning brain. It also involves being able to act and speak reasonably intelligently. (shrink)

As a typical subject, you experience a variety of paradigmatically temporal phenomena. Looking out of the window in the English summer, you can see leaves swaying in the breeze and hear the pitter-patter of raindrops steadily increasing against the window. In discussions of temporal experience, and through reflecting on examples such as those offered, two phenomenological claims are widely – though not unequivocally – accepted: firstly, you perceptually experience motion and change; secondly, while more than a momentary state of affairs (...) is presented in your ongoing perceptual experience, that which is presented nonetheless seems to be of a quite limited temporal extent. These two claims are frequently tied to the notion of the specious present. However, there has recently been a push back against the supposed link between perceived motion and the specious present. I argue that there are two ways of understanding this link, and while one has recently been the target of criticism, the other withstands such criticism. My overarching aim is to clarify the notion of the specious present through a discussion of the notion’s origins, in addition to recent criticism directed at the notion, with the hope of reframing how contemporary debates proceed.

The “looks” of things are frequently invoked (a) to account for the epistemic status of perceptual beliefs and (b) to distinguish perceptual from inferential beliefs. ‘Looks’ for these purposes is normally understood in terms of a perceptual experience and its phenomenal character. Here I argue that there is also a nonexperiential sense of ‘looks’—one that relates to cognitive architecture, rather than phenomenology—and that this nonexperiential sense can do the work of (a) and (b).

Seminal work in moral neuroscience by Joshua Greene and colleagues employed variants of the well-known trolley problems to identify two brain networks which compete with each other to determine moral judgments. Greene interprets the tension between these brain networks using a dual process account which pits deliberative reason against automatic emotion-driven intuitions: reason versus passion. Recent neuroscientific evidence suggests, however, that the critical tension that Greene identifies as playing a role in moral judgment is not so much a tension between (...) reason and passion, but a tension between distinct forms of deliberative reasoning: analytic versus empathetic. In this paper we present results from several new studies supporting this alternative hypothesis. (shrink)

Domestic violence and abuse (DVA) are at last coming to be recognised as serious global public health problems. Nevertheless, many women with personal histories of DVA decline to disclose them to healthcare practitioners. In the health sciences, recent empirical work has identified many factors that impede DVA disclosure, known as barriers to disclosure. Drawing on recent work in social epistemology on testimonial silencing, we might wonder why so many people withhold their testimony and whether there is some kind of epistemic (...) injustice afoot here. In this paper, I offer some philosophical reflections on DVA disclosure in clinical contexts and the associated barriers to disclosure. I argue that women with personal histories of DVA are vulnerable to a certain form of testimonial injustice in clinical contexts, namely, testimonial smothering, and that this may help to explain why they withhold that testimony. It is my contention that this can help explain the low rates of DVA disclosure by patients to healthcare practitioners. (shrink)

Much current work in the social sciences seeks to understand the effects of trust and social capital on economic and political outcomes. However, the sources of trust remain unclear. In this article, the authors articulate a basic theory of the relationship between institutions and trust. The authors apply this theory to industrial districts, geographically concentrated areas of small firm production, which involve extensive cooperation in the production process. Changes in power relations affect patterns of production;the authors suggest that they also (...) have knock-on consequences for trust and cooperation among actors. (shrink)
