Trope theory is the view that the world consists (wholly or partly) of particular qualities, or tropes. This admittedly thin core assumption leaves plenty of room for variation. Still, most trope theorists agree that their theory is best developed as a one-category theory according to which there is nothing but tropes. Most hold that ‘sameness of property’ should be explained in terms of resembling tropes. And most hold that concrete particulars are made up from tropes in compresence (for an overview, (...) including an introduction to some alternative versions of the view, cf. Maurin, 2014). D. M. Armstrong disagrees. He thinks the world is a world of immanent universals, the thin particulars in which those universals are instantiated, and the states of affairs that—thereby—exist. He holds that ‘sameness of property’ should be explained in terms of numerically identical universals or—if the resembling things are the universals themselves—in terms of partially identical universals. And he believes that concrete particulars are made up from ‘thin particulars’ in which a (sufficient) number of universals are instantiated. In spite of their disagreements, proponents of tropes owe Armstrong a debt of gratitude. First, for being one of the theory’s earliest, most serious, and—not least—most prominent, critics (Armstrong for the first time considers, and rejects, what he then labels ‘particularism’, in his 1978a). But also for being one of the theory’s most ardent champions. Already in his 1989a, Armstrong regrets his 1978-rejection of the view. Equivalence classes of exactly resembling tropes, he now admits, for most purposes “serve as an excellent substitute for universals” (Armstrong 1989a, 122). But then why isn’t Armstrong a trope theorist? In this paper, Armstrong’s main reasons for rejecting the trope view are critically scrutinized. All of them, it is maintained, fail to convince. If this argument is accepted, Armstrong seems to have no—or, at least, no good—reason for not accepting the existence of tropes. But, then, ought Armstrong to have been a trope theorist? If the ‘best’ version of the trope view turns out to be ontologically more parsimonious than Armstrong’s own theory of universals, then, yes. That there is a version of the trope view, a version that is not (or, at least not seriously) considered by Armstrong, that is ontologically more parsimonious than the universals view, is argued in the next section. Why none of Armstrong’s reasons for preferring universals to tropes manage to convince, is explained in the section after that. First, however, and in order to avoid a common misunderstanding of the trope view and, as a consequence, of why one ought to reject it, a few more words about the core-difference between tropes and universals, and about how this difference matters (as well as does not matter) to what—and how well—these theories explain.

According to Johansson (2009: 22) an infinite regress is vicious just in case “what comes first [in the regress-order] is for its definition dependent on what comes afterwards.” Given a few qualifications (to be spelled out below (section 3)), I agree. Again according to Johansson (ibid.), one of the consequences of accepting this way of distinguishing vicious from benign regresses is that the so-called Russellian Resemblance Regress (RRR), if generated in a one-category trope-theoretical framework, is vicious and that, therefore, the (...) existence of tropes only makes sense if trope-theory is understood (minimally) as a two-category theory which accepts, besides the existence of tropes, also the existence of at least one universal: resemblance.1 I disagree. But how can that be? How can Johansson and I agree about what distinguishes a vicious from a benign regress, yet disagree about which regresses are vicious and which are benign? In this paper I attempt to answer that question by first setting out and defending the sense of viciousness which both Johansson and I accept, only to then argue that to be able to determine if a particular regress is vicious in this sense, more than features intrinsic to the regress itself must be taken into account. This is why, although the RRR as originally set out by Russell is vicious, the seemingly identical resemblance regress which ensues in a one-category (standard) trope-theoretical context is not (provided, that is, that we accept certain views about how the nature of tropes relates to the resemblance between tropes, and given that we set our theory in a truthmaker theoretical framework – all of which are standard assumptions for proponents of (the standard-version of) the trope-theory).2.

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)

We use genomic information to tell us stories of evolutionary origins. But what does it mean when different genomes report wildly different accounts of lineage history? This genomic “discordance” can be a consequence of a fascinating suite of natural history and evolutionary phenomena, from the different inheritance mechanisms of nuclear versus cytoplasmic (mitochondrial and plastid) genomes to hybridization and introgression to horizontal transfer. Here, we explore how we can use these distinct genomic stories to provide new insights into the maintenance (...) of sexual reproduction, one of the most important unanswered questions in biology. We focus on the strikingly distinct nuclear versus mitochondrial versions of the story surrounding the origin and maintenance of asexual lineages in Potamopyrgus antipodarum, a New Zealand freshwater snail. While key questions remain unresolved, these data inspire multiple testable hypotheses that can be powerfully applied across a broad range of taxa toward a deeper understanding of the causes and consequences of mitonuclear discordance, the maintenance of sex, and the origin of new asexual lineages.

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)

Grounding theorists insist that grounding and explanation are intimately related. This claim could be understood as saying either that grounding ‘inherits’ its properties from explanation or it could be interpreted as saying that grounding plays an important—possibly an indispensable—role in metaphysical explanation. Or both. I argue that saying that grounding ‘inherits’ its properties from explanation can only be justified if grounding is explanatory by nature, but that this view is untenable. We ought therefore to be ‘separatists’ and view grounding and (...) explanation as distinct. As it turns out, though, once grounding has been in this sense distinguished from the explanation it backs, the view that the role grounding plays in explanation justifies its introduction ends up in serious trouble. I conclude that the role grounding plays in explanation does not justify attributing to grounding whatever nature we think it has, and it most likely does not give us any special reason to think grounding exists.

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.

Descartes a entrepris de détruire la pratique aristotélicienne de la philosophie : à son savoir seulement probable, les Regulae, puis les Essais opposent une science certaine d'objets clairs et distincts. Mais cette instauration concerne aussi, peut-être même d'abord, l'idéal pratique qu'Aristote ne cesse de viser dans les sciences théorétiques : le sage parvient à la félicité par l'exercice même d'une connaissance si parfaite qu'elle imite celle du dieu, qui pense sa pensée en acte et éternellement. Descartes met décidément en crise (...) la félicité par la contemplation, dont la pensée médiévale avait hérité d'Aristote. Pourtant, une autre figure de la félicité se dégage tout aussi indiscutablement de l'entreprise cartésienne : la méthode, la certitude scientifique qu'elle permet et les principes métaphysiques qui assurent l'une et l'autre restent, à chaque moment, solidaires d'une attitude et d'une ambition proprement morales - la volonté infinie aboutit à la générosité, où la considération du bon usage de notre libre-arbitre permet le - contentement de soi-même -. Ainsi la philosophie atteint-elle, pour Descartes aussi, à une félicité. Mais à une félicité volontaire et non plus contemplative. On tentera donc d'abord de mesurer, dans différents champs de la philosophie cartésienne, l'impact de la certitude jusque sur les questions d'éthique ; ensuite, de souligner la référence constante, quoique souvent implicite, de Descartes à la félicité telle qu'Aristote la visait ; enfin, de suivre leur dialogue au fil conducteur de leurs versions divergentes, mais complices, de l'admiratio et du thaumazein.

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

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)

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)

The treatise attempts to approach and deal with some of the most fundamental problems facing anyone who wishes to uphold some version of the so-called theory of tropes. Three assumptions serve as a basis for the investigation: tropes exist, only tropes exist, and a one-category trope-theory along these lines should be developed so that the tropes it postulates are able to serve as truth-makers for all kinds of atomic propositions. Provided that these assumptions are accepted, it is found that the (...) trope-theorist will have to deal with two important problems. First, some atomic propositions seem to require universal truth-makers. Second, some atomic propositions seem to require concrete truth-makers. As tropes are abstract particulars, it follows that the trope-theorist, in order to fulfil assumption, must provide an account of exactly how he or she could construct universality and concreteness from his or her basic stock of tropes. In the treatise such constructions are attempted and some basic problems with such constructions are revealed. Although these problems are serious enough it is argued that it is nevertheless possible to deal with these basic issues while staying squarely within the boundaries of a one-category trope-ontology.

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)

Trope theory is the view that the world is a world of abstract particular qualities. But if all there is are tropes, how do we account for the truth of propositions ostensibly made true by some concrete particular? A common answer is that concrete particulars are nothing but tropes in compresence. This answer seems vulnerable to an argument (first presented by F. H. Bradley) according to which any attempt to account for the nature of relations will end up either in (...) contradiction, nonsense, or will lead to a vicious infinite regress. I investigate Bradley’s argument and claim that it fails to prove what it sets out to. It fails, I argue, because it does not take all the different ways in which relation and relata may depend on one another into account. If relations are entities that are distinct from yet essentially dependent upon their relata, the Bradleyan problem is solved. We are then free to say that tropes in compresence are what make true propositions ostensibly made true by concrete particulars. (shrink)

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 F. H. Bradley first formulated his famous regress argument philosophers have been hard at work trying to refute it. The argument fails, it has been suggested, either because its conclusion just does not follow from its premises, or it fails because one or more of its premises should be given up. In this paper, the Bradleyan argument, as well as some of the many and varied reactions it has received, is scrutinized.

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.

That there could be ontologically complex concrete particulars is self-evidently true. A reductio may however be formulated which contradicts this truth. In this paper I argue that all of the reasonable ways in which we might refute this reductio will require the existence of at least some tropes.
