Byrne & Hilbert propose that color can be identified with explicit properties of physical surfaces. I argue that this claim must be qualified to take into account constraints needed to make recovery of surface color information possible. When these constraints are satisfied, then a biological visual system can establish a correspondence between perceived surface color and specific surface properties.

For each positive n , two alternative axiomatizations of the theory of strings over n alphabetic characters are presented. One class of axiomatizations derives from Tarski's system of the Wahrheitsbegriff and uses the n characters and concatenation as primitives. The other class involves using n character-prefixing operators as primitives and derives from Hermes' Semiotik. All underlying logics are second order. It is shown that, for each n, the two theories are definitionally equivalent [or synonymous in the sense of deBouvere]. It (...) is further shown that each member of one class is synonymous with each member of the other class; thus that all of the theories are definitionally equivalent with each other and with Peano arithmetic. Categoricity of Peano arithmetic then implies categoricity of each of the above theories. (shrink)

In this incisive new book one of Britain's most eminent philosophers explores the often overlooked tension between voluntariness and involuntariness in human cognition. He seeks to counter the widespread tendency for analytic epistemology to be dominated by the concept of belief. Is scientific knowledge properly conceived as being embodied, at its best, in a passive feeling of belief or in an active policy of acceptance? Should a jury's verdict declare what its members involuntarily believe or what they voluntarily accept? And (...) should statements and assertions be presumed to express what their authors believe or what they accept? Does such a distinction between belief and acceptance help to resolve the paradoxes of self-deception and akrasia? Must people be taken to believe everything entailed by what they believe, or merely to accept everything entailed by what they accept? Through a systematic examination of these problems, the author sheds new light on issues of crucial importance in contemporary epistemology, philosophy of mind, and cognitive science. (shrink)

Laurence Goldstein gives a straightforward and lively account of some of the central themes of Wittgenstein's writings on meaning, mind, and mathematics.

La recherche des causes apparaît à la fois comme un impérieux besoin de l'esprit humain et, sous la plume de nombreux acteurs du développement historique des connaissances, comme un obstacle. L'examen comparé des tendances majeures du raisonnement commun et des théories scientifiques actuellement enseignées fait apparaître des écarts importants quant à leur statut du point de vue de la causalité. " Donc ", " alors ", " ensuite " : ce trio de vocables résume la question que posent la part (...) de l'implication logique et celle des relations temporelles entre cause et effet. La causalité au sens où les physiciens l'entendent se distingue ainsi du lien qu'une relation pose entre grandeurs prises au même instant. Le débat rejoint ainsi la notion de fonction - et son nécessaire développement vers les fonctions de plusieurs variables - ainsi que celle des associations probabilistes entre grandeurs. Cet ouvrage invite à un examen croisé de la manière dont ce thème est abordé dans différentes disciplines (mathématiques, sciences physiques, biologie, histoire-géographie), sous le double regard de la didactique et de l'épistémologie.

A comprehensive defence of the rationalist view that insight independent of experience is a genuine basis for knowledge.

Johnathan Cohen's book provides a lucid and penetrating treatment of the fundamental issues of contemporary analytical philosophy. This field now spans a greater variety of topics and divergence of opinion than fifty years ago, and Cohen's book addresses the presuppositions implicit to it and the patterns of reasoning on which it relies.

The book was planned and written as a single, sustained argument. But earlier versions of a few parts of it have appeared separately. The object of this book is both to establish the existence of the paradoxes, and also to describe a non-Pascalian concept of probability in terms of which one can analyse the structure of forensic proof without giving rise to such typical signs of theoretical misfit. Neither the complementational principle for negation nor the multiplicative principle for conjunction applies (...) to the central core of any forensic proof in the Anglo-American legal system. There are four parts included in this book. Accordingly, these parts have been written in such a way that they may be read in different orders by different kinds of reader. (shrink)

In “Internalism and Externalism,” Laurence BonJour suggests that the contemporary epistemological debate over internalism and externalism concerns the formulation of the justification or warrant condition in an account of knowledge. The internalist requires that for a belief to meet this condition, all of the necessary elements must be cognitively accessible to the believer, whereas the externalist claims that at least some such elements do not need to be accessible to the believer. BonJour gives an overview of this dispute. He (...) suggests that the opposition between the two views is less straightforward than has usually been thought. He proposes, in addition, that each of them has valuable roles to play in major epistemological issues, even though the internalist approach is more fundamental in an important way. (shrink)

One of the many problems that would have t o be solved by a satisfactory theory of empirical knowledge, perhaps the most central is a general structural problem which I shall call the epistemic regress problem: the problem of how to avoid an in- finite and presumably vicious regress of justification in ones account of the justifica- tion of empirical beliefs. Foundationalist theories of empirical knowledge, as we shall see further below, attempt t o avoid the regress by locating a (...) class of empirical beliefs whose justification does not depend on that of other empirical beliefs. Extemalist theories, the topic of the present paper, represent one species of foundationalism. (shrink)

Two new philosophical problems surrounding the gradation of certainty began to emerge in the 17th century and are still very much alive today. One is concerned with the evaluation of inductive reasoning, whether in science, jurisprudence, or elsewhere; the other with the interpretation of the mathematical calculus of change. This book, aimed at non-specialists, investigates both problems and the extent to which they are connected. Cohen demonstrates the diversity of logical structures that are available for judgements of probability, and explores (...) the rationale for their appropriateness in different contexts of application. Thus his study deals with the complexity of the underlying philosophical issues without simply cataloging alternative conceptions or espousing a particular "favorite" theory. (shrink)

This book is concerned with the alleged capacity of the human mind to arrive at beliefs and knowledge about the world on the basis of pure reason without any dependence on sensory experience. Most recent philosophers reject the view and argue that all substantive knowledge must be sensory in origin. Laurence BonJour provocatively reopens the debate by presenting the most comprehensive exposition and defence of the rationalist view that a priori insight is a genuine basis for knowledge. This important (...) book will be at the centre of debate about the theory of knowledge for many years to come. (shrink)

This book offers a unique synthesis of past and current work on the structure, meaning, and use of negation and negative expressions, a topic that has engaged thinkers from Aristotle and the Buddha to Freud and Chomsky. Horn's masterful study melds a review of scholarship in philosophy, psychology, and linguistics with original research, providing a full picture of negation in natural language and thought; this new edition adds a comprehensive preface and bibliography, surveying research since the book's original publication.

Technology used in online marketing has advanced to a state where collection, enhancement and aggregation of information are instantaneous. This proliferation of customer information focused technology brings with it a host of issues surrounding customer privacy. This article makes two key contributions to the debate concerning digital privacy. First, we use theories of justice to help understand the way consumers conceive of, and react to, privacy concerns. Specifically, it is argued that an important component of consumers' privacy concerns relates to (...) fairness judgments, which in turn comprise of the two primary components of distributive and procedural justice. Second, we make a number of prescriptions, aimed at both firms and regulators, based on the notion that consumers respond to perceived privacy violations in much the same way they would respond to an unfair exchange.

Ever since Plato it has been thought that one knows only if one's belief hits the mark of truth and does so with adequate justification. The issues debated by Laurence BonJour and Ernest Sosa concern mostly the nature and conditions of such epistemic justification, and its place in our understanding of human knowledge. Presents central issues pertaining to internalism vs. externalism and foundationalism vs. virtue epistemology in the form of a philosophical debate. Introduces students to fundamental questions within epistemology (...) while engaging in contemporary debates. Written by two of today’s foremost epistemologists. Includes an extensive bibliography.

In lieu of an abstract, here is a brief excerpt of the content:The Past and Future of Utopian StudiesLaurence Davis (bio)This critical forum on “The Past and Future of Utopian Studies” originated as a roundtable discussion at the conference, “Opening Utopia: New Directions in Utopian Studies,” held at the University of Brighton in July 2022. The title of the conference reflected a determination on the part of the program coordination team—Patricia McManus (University of Brighton), Laurence Davis (University College Cork), (...) Siân Adiseshiah (Loughborough University), Antonis Balasopoulos (University of Cyprus), Tom Moylan (University of Limerick), Michael G. Kelly (University of Limerick), Emrah Atasoy (Cappadocia University), and Ross Sparkes (University of Brighton)—to make the conference an inclusive and potentially radically transformative event, one that would challenge entrenched orthodoxies in the field of utopian studies and help scholars and activists chart new directions in utopian scholarship and practice.This transformative ethos was reflected in the collaboratively produced conference call for papers, which stipulated that the event was dedicated to an exploration of radical utopian thinking and revolutionary praxis. The conference, we emphasized, was intended to create a welcoming and broadly [End Page 478] inclusive space where participants could explore the role of utopian thinking, imagination, and practice in addressing some of the fundamental challenges of our times. Towards this end we appended to the call a section, entitled “USS and Utopia Beyond the University,” in which we noted that our aim was to design a program that would center work intended to blur or break the well-policed and expensive borders between the university and the communities within which universities sit. We proposed, and indeed later fulfilled the promise, to work with local activists in Brighton to establish some in-person and remote-access events that would highlight and explore radical hope as it is present in the politics of migrant solidarity, co-housing initiatives, and anarchist and queer groups and spaces. We also explicitly invited contributions from those working outside the formal limits of academia or who were inside academic spaces pushing out. The enthusiastic response to the call for papers exceeded all expectations, and the resulting conference program was exceptionally varied and promising and indeed suggestive of many possible new directions in utopian studies. What follows in this special section of Utopian Studies is a product of one very lively five-person conference panel that I co-organized with Antonis Balasopoulos (University of Cyprus).The chief impetus for the transformation from conference panel to special journal section was an email invitation from the then-editor of Utopian Studies, who had attended the session and who subsequently invited us to revise and elaborate the talks for publication in the journal. Interestingly, the journal editor suggested that the contributions might provide answers to two questions: first, “where do you see the value of utopian studies in our dark times?” and second, “how can utopia and utopianism inspire activism and political changes?”In response, and speaking in my capacity as the panel chair and prospective editor of the special section, I noted that while it would be fascinating to see the contributors address questions of the value of utopian studies in our dark times, and specifically how utopia and utopianism might inspire activism and political change, such a remit would not get to the heart of what was distinctive about either our panel or the Brighton conference as a whole. The Brighton conference was dedicated specifically to an exploration of radical utopian thinking and revolutionary practice. And its title, “Opening Utopia: New Directions in Utopian Studies” suggested that utopia can be a catalyst for transformative change only if the study of utopia(s) is itself open, or “opened,” to radical influences. In our panel we explored both the past and some possible futures of utopian studies and considered “new [End Page 479] directions” that might facilitate more radical utopian thinking and revolutionary practice. While all of the contributors celebrated utopia’s transformative potential, they also criticized aspects of the field of utopian studies that arguably have limited that transformative potential, including its “blind spots” in relation to the “organizational imaginary” (Balasopoulos), its own privileged “whiteness” and colonial prerogatives (Edwards), its Anglo-American focus and tendency to overlook significant social movements outside...

In this paper I present a novel account of achievement and I argue that, all other things being equal, the presence of this particular type of achievement in a person’s life makes that life more meaningful. In arguing for this conclusion, I explore the connections between m-achievements and a person’s self-conception and especially the idea that m-achievements provide a reason for the revision of one’s self-conception.

In Epistemology, Laurence Bonjour introduces the serious philosophy student to the history and concepts of epistemology, while simultaneously challenging them to take an active part in its ongoing debates. The text reflects BonJour's conviction that the place to start any discussion of the theories of knowledge is with the classical problems, beginning with and centered around Descartes.

Jon Shields's finding—that certain evangelical pro‐life activist groups are more interested in deliberative discussions about abortion than are pro‐choice activists—is wrong on methodological, normative, and philosophical grounds. He generalizes about pro‐life civility from a small, trained sample group, and ignores possibly important variables that would explain pro‐choicers' incivility. Further, politeness is not necessarily a requirement of democratic deliberation—which entails not forcing one's own beliefs on the public, as pro‐lifers manifestly are trying to do, despite their calm demeanor. Conversely, some pro‐choicers' (...) refusal to engage in debates is not a deliberative failure, as Shields suggests, as deliberation includes such things as campaigning and canvassing. Lastly, Shields, and the pro‐lifers he has observed, use the weakest of the pro‐choice arguments, instead of focusing on the best academic work in the field. (shrink)
