Graham Priest presents an expanded edition of his exploration of the nature and limits of thought. Embracing contradiction and challenging traditional logic, he engages with issues across philosophical borders, from the historical to the modern, Eastern to Western, continental to analytic.

Do perceptual states necessarily constitute evidence epistemically supporting corresponding perceptual beliefs? Susanna Schellenberg thinks so. She argues that perceptual states, veridical or not, necessarily provide (or constitute) a kind of evidence (for the existence of the truth-maker) supporting corresponding perceptual beliefs. She uses “phenomenal evidence” as a label for this kind of evidence and calls her argument “The Phenomenal Evidence Argument.” Having introduced her project, we offer a reconstruction of Schellenberg’s argument. A key premise has it that, necessarily, for items (...) with a function, fulfillment of the function (the good case) is explanatorily and metaphysically prior to function failure (the bad case). We suggest that the etiological theory of functions renders this key premise plausible. However, Schellenberg rejects the etiological theory of functions and likewise the idea that the epistemic or warranting force of perceptual states is grounded in their being reliably linked to veridical perception. But then what supports the key premise? Schellenberg argues that accurate perception is a part of the nature of perceptual capacities because the nature of perceptual capacities is explained in terms of their function, and their function is to represent accurately. We suggest that Schellenberg is committed to an understanding of priority which doesn’t require any actual good cases—just possible ones. This reading, we argue, is too weak to support the key premise. Given Schellenberg’s commitments, it is not necessarily the case that perceptual states are evidence for a corresponding perceptual belief. Before concluding we discuss an overgeneralization objection. (shrink)

How should we undertand the role of norms—especially epistemic norms—governing assertive speech acts? Mitchell Green (2009) has argued that these norms play the role of handicaps in the technical sense from the animal signals literature. As handicaps, they then play a large role in explaining the reliability—and so the stability (the continued prevalence)—of assertive speech acts. But though norms of assertion conceived of as social norms do indeed play this stabilizing role, these norms are best understood as deterrents and not (...) as handicaps. This paper explains the stability problem for the maintenance of animal signals, and so human communication, for we are animals too, after all; the mechanics of the handicap principle; the role of deterrents and punishments as an alternative mechanism; and the role of social norms governing assertion for the case of human communication.

Teleosemantics seeks to explain meaning and other intentional phenomena in terms of their function in the life of the species. This volume of new essays from an impressive line-up of well-known contributors offers a valuable summary of the current state of the teleosemantics debate.

Analogies are offered to guide our explanatory responses to the fine-tuning of the universe. Situations that prompt us to reject an explanation involving a single chance event are presented as analogous to the fine-tuning. Thus, by analogy, we are prompted to reject an explanation of the fine-tuning involving a single universe fine-tuned by chance. But if the alleged analogues are not analogous they misguide us. I argue that the alleged analogues are not analogous and hence they do misguide our explanatory (...) responses to the fine-tuning. I use William Dembski’s work on eliminating chance explanations for “specified” events of small probability to illustrate the misguiding nature of the analogies. (shrink)

In 'Perceptual Entitlement' (PPR 2003), Tyler Burge argues that on his teleological reliabilist account of perceptual warrant, warrant will persist in non-normal conditions, even radical skeptical scenarios like demon worlds. This paper explains why Burge's explanation falls short. But if we distinguish two grades of warrant, we can explain, in proper functionalist, teleological reliabilist terms, why warrant should persist in demon worlds. A normally functioning belief-forming process confers warrant in all worlds, provided it is reliable in normal conditions when functioning (...) normally. The first grade requires normal functioning. The second grade also requires being situated in normal conditions. (shrink)

For some aestheticians, Wittgenstein's notion of _seeing as (or aspect perception) could be used to explain perception of artworks as artworks (artistic appreciation). This paper urges that the idea of aspect perception cannot provide such a model, even for a perceptualist about artistic appreciation (like the author). First, this would be inconsistent with Wittgenstein's argumentative strategy in key passages in _Philosophical Investigations Part Two. Second, the characteristics of aspect perception make it unsuitable as a model, whatever Wittgenstein's intentions. Moreover (one (...) of Wittgenstein's own contentions), a suitably rich account of perception does not require this appeal to aspects. (shrink)

We review the "Entitlement" projects of Tyler Burge and Crispin Wright in light of recent work from and surrounding both philosophers. Our review dispels three misunderstandings. First, Burge and Wright are not involved in a common “entitlement” project. Second, though for both Wright and Burge entitlement is the new notion, “entitlement” is not some altogether third topic not clearly connected to the nature of knowledge or the encounter with skepticism. Third, entitlement vs. justification does not align with the externalism vs. (...) internalism distinction. (shrink)

C.A.J. Coady, in his book Testimony: A Philosophical Study (Oxford: Clarendon Press, 1992), offers conditions on an assertion that p to count as testimony. He claims that the assertion that p must be by a competent speaker directed to an audience in need of evidence and it must be evidence that p. I offer examples to show that Coady’s conditions are too strong. Testimony need not be evidence; the speaker need not be competent; and, the statement need not be relevant (...) or directed to someone in need of evidence. I give alternative conditions. Coady was led into the stronger conditions by investigating testimony as it occurs in legal contexts, where special steps are taken to ensure that testimony provides the jury or the judge with evidence by a competent speaker that is relevant to the disputed question of the guilt or innocence of the defendant.

Alvin Plantinga argues by counterexample that no naturalistic account of functions is possible--God is then the only source for natural functions. This paper replies to Plantinga's examples and arguments. Plantinga misunderstands naturalistic accounts. Plantinga's mistakes flow from his assimilation of functional notions in general to functions from intentional design in particular.

In Contradiction advocates and defends the view that there are true contradictions (dialetheism), a view that flies in the face of orthodoxy in Western philosophy since Aristotle. The book has been at the center of the controversies surrounding dialetheism ever since its first publication in1987. This second edition of the book substantially expands upon the original in various ways, and also contains the author's reflections on developments over the last two decades. Further aspects of dialetheism are discussed in the companion (...) volume, Doubt Truth to be a Liar, also published byOxford University Press in 2006. (shrink)

According to our folk theory of lying, liars leak observable cues of their insincerity, observable cues that make it easy to catch a liar in real time. Various prominent social epistemologists rely on the correctness of our folk theory as empirically well-confirmed when building their normative accounts of the epistemology of testimony. Deception detection research in communication studies, however, has shown that our folk-theory is mistaken. It is not empirically well-confirmed but empirically refuted. Michaelian (2010) and Shieber (2012) have already (...) discussed some of this literature and its relevance for epistemology, especially for the most worked out reliance on our folk theory by Elizabeth Fricker (1994, 2016, 2017a, 2024). Fricker (2016) raises a reasonable objection to their presentations of the research: is the research ecologically valid? Do the experiments in the lab carry over to real life? This chapter conveys the methodology of the research, defends its ecological validity, and addresses further research on the nature and frequency of lies in ordinary life. Social epistemologists stand to gain from understanding the nuts and bolts of deception detection research and its findings. The chapter concludes with a detailed examination of Fricker’s relilance on folk theory in her “local reductionist” epistemology of testimony. Further areas of research relevant to social epistemology are listed. (shrink)

Tyler Burge first introduced his distinction between epistemic entitlement and epistemic justification in ‘Content Preservation’ in 1993. He has since deployed the distinction in over twenty papers, changing his formulation around 2009. His distinction and its basis, however, is not well understood in the literature. This chapter distinguishes two uses of ‘entitlement’ in Burge, and then focuses on his distinction between justification and entitlement, two forms of warrant, where warrants consists in the exercise of a reliable belief-forming competence. Since he (...) draws the distinction in terms of reasons, this chapter brings his account of reasons altogether in one place. The chapter introduces a decision-procedure for classifying warrants as justifications or entitlements. The distinction between justification and entitlement is not the same as the inferential vs. non-inferential distinction. The chapter distinguishes inference from processing, thinking, reasoning, and critically reasoning. Burge’s new formulation of the distinction was driven by the recognition of non-accessible modular reasons. Three kinds of access are distinguished. (shrink)

Mathematical pluralism notes that there are many different kinds of pure mathematical structures—notably those based on different logics—and that, qua pieces of pure mathematics, they are all equally good. Logical pluralism is the view that there are different logics, which are, in an appropriate sense, equally good. Some, such as Shapiro, have argued that mathematical pluralism entails logical pluralism. In this brief note I argue that this does not follow. There is a crucial distinction to be drawn between the preservation (...) of truth and the preservation of truth-in-a-structure; and once this distinction is drawn, this suffices to block the argument. The paper starts by clarifying the relevant notions of mathematical and logical pluralism. It then explains why the argument from the first to the second does not follow. A final section considers a few objections. (shrink)

The topic of my dissertation is selfhood. I aim to explain what a self is such that it can sometimes succeed and other times fail at thinking and acting autonomously. I open by considering a failure of autonomy to which I return throughout the dissertation. The failure is that of self-deception. I show that in common cases of self-deception the self-deceived individual fails, due to a motive on his part, to be able to explain the cause of some belief or (...) action of his. There are several philosophical projects that arise when one reflects on this failure. They are presented by the following questions: what are our minds like, such that this failure is possible? For what should we criticize the self-deceived individual, given that he has a motivated lack of self-knowledge but does not know he is so motivated? Is the self-deceived individual epistemically criticizable for lacking explanatory self-knowledge in a way that he is not criticizable for lacking knowledge that would help him explain another's thoughts and actions? By answering these questions I provide an account of the rational unity that goes missing in self-deception and in the related phenomenon of epistemic akrasia. This unity can—and I argue, should—be present in bodily action as well. When a person acts without this unity, he acts in a weak-willed, akratic way. I provide an account of this disunity, which, when added to my account of the disunity of self-deception, reveals the rational unity of an autonomous agent, the rational unity of the self. (shrink)

Folk psychological realism is the view that folk psychology is true and that people really do have propositional attitudes, whereas anti-realism is the view that folk psychology is false and people really do not have propositional attitudes. We argue that anti-realism is not worthy of acceptance and that realism is eminently worthy of acceptance. However, it is plainly epistemically possible to favor either of two forms of folk realism: scientific or non-scientific. We argue that non-scientific realism, while perhaps unpopular among (...) philosophers of mind, is a distinct form of realism from scientific realism, and that it is not yet knowable whether scientific or non-scientific realism is true. We also outline how adopting realism, but remaining neutral between scientific and non-scientific realism, offers fresh insights into such topics as instrumentalism, supervenience, the language of thought hypothesis, and elimin-ativism.

René Guénon is a major figure for anyone who recognises a need to rediscover the spiritual roots from which Western society has become so comprehensively alienated. Immersing himself in the search for spiritual truth, he chose Islam as the vehicle for his spiritual life. Settling in Egypt, he clarified and deepened our understanding of the teachings of traditional metaphysics, his central message being that there is at the source of all humanity's traditions a 'Primordial Tradition' -- a Universal Metaphysics which (...) sets out the principles that underlie this Tradition. The truths it embodies are universal and unchanging, and form part of a unified body of higher knowledge which transcends the multiplicity of religious dogmas and philosophical systems that abound in Western society. He wrote about the need to transcend the formal and emotional aspect of religion in order to prepare ourselves for an understanding of 'pure metaphysics'. He explained how traditional societies achieved this, exploring the symbols used, in order to help individuals forward to levels of understanding which are otherwise inaccessible to minds blinkered by the limitations of the currently prevailing Western approach to existence and its meaning.

I argue that the Hume of the Treatise maintains an account of knowledge according to which (i) every instance of knowledge must be an immediately present perception (i.e., an impression or an idea); (ii) an object of this perception must be a token of a knowable relation; (iii) this token knowable relation must have parts of the instance of knowledge as relata (i.e., the same perception that has it as an object); and any perception that satisfies (i)-(iii) is an instance (...) of knowledge. I then apply this account to the case of sense perception. I argue that Hume holds that relations of impressions can be intuited, are knowable, and are necessary. For Hume, these relations constitute sensory knowledge. While Hume is rightly labeled an empiricist for many reasons, a close inspection of his account of knowledge reveals yet another way in which he deserves the label. (shrink)

How engineers know, and act on that knowledge, has a profound impact on society. Consequently, the analysis of engineering knowledge is one of the central challenges for the philosophy of engineering. In this article, we present a thematic multidisciplinary conceptual survey of engineering epistemology and identify key areas of research that are still to be comprehensively investigated. Themes are organized based on a survey of engineering epistemology including research from history, sociology, philosophy, design theory, and engineering itself. Five major interrelated (...) themes are identified: the relationship between scientific and engineering knowledge, engineering knowledge as a distinct field of study, the social epistemology of engineering, the relationship between engineering knowledge and its products, and the cognitive aspects of engineering knowledge. We discuss areas of potential future research that are underdeveloped or “undone.”. (shrink)

Saul Kripke’s work on the semantics of non-normal modal logics introduced the idea of non-normal worlds, worlds where certain connectives behave differently from the way in which they behave in the worlds of normal modal logics. Such worlds may be thought of as impossible worlds, though Kripke did not, himself, talk of them in this way. Since Kripke’s invention, the notion of an impossible world has undergone much fruitful development and application. Impossible worlds may be of different kinds—or maybe different (...) degrees of impossibility; and these worlds have found application in many areas where hyperintensionality appears to play a significant role: intentional mental states, counterfactuals, meaning, property theory, to name but a few areas. But what, exactly, is an impossible world? How is it best to characterise the notion? To date, the notion is used more by example than by definition. In this paper I will investigate the question, and propose a general characterisation, suitable for all standard purposes and tastes. (shrink)

The paper addresses the intuitions of aestheticians concerning a fundamental contrast between the judgement, appreciation, and interest appropriate to artworks and those judgements, appreciations, and interests appropriate to all the other (non-art) cases of aesthetic interest. Then terms such as beauty must amount to something different in art-cases from that in other (aesthetic) cases. For the fact of being an artwork is transfigurational, allowing artistic properties to be (truly) ascribed. In arguing against the univocality of terms such as beauty (by (...) stressing occasion-sensitivity), the paper rejects the idea of a ‘look of the thing’ shared by art and non-art. And the pervasiveness of this artistic/aesthetic contrast is urged. (shrink)

Ancient Greek Philosophy From Thales, who is often considered the first Western philosopher, to the Stoics and Skeptics, ancient Greek philosophy opened the doors to a particular way of thinking that provided the roots for the Western intellectual tradition. Here, there is often an explicit preference for the life of reason and rational thought. We … Continue reading Ancient Greek Philosophy →.

The inherence heuristic is characterized as part of an instantiation of a more general model that describes the interaction between undeveloped intuitions, produced by System 1 heuristics, and developed beliefs, constructed by System 2 reasoning. The general model is described and illustrated by examining another instantiation of the process that constructs belief in objective moral value.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hegel's Century: Alienation and Recognition in a Time of Revolution by Jon StewartClay GrahamJon Stewart. Hegel's Century: Alienation and Recognition in a Time of Revolution. Cambridge: Cambridge University Press, 2021. Pp. xi + 338. Hardback, $39.99.Hegel's Century serves as (yet another) important contribution in Jon Stewart's ever-expanding research in nineteenth-century philosophy. The central premise of this monograph explores Hegel's pan-European legacy and argues that Hegelian concepts are fundamental (...) for understanding major philosophical themes of the era, especially on the European continent. Dominant among these themes are alienation and recognition, particularly their adaptation to political philosophy and religious criticism. Stewart develops his theses via a series of chapters dedicated to individual thinkers: Heine, Feuerbach, Bauer, Marx, Kierkegaard, Dostoyevsky, Bakunin, and Engels. In each case, the concepts of alienation and recognition are teased out of primary texts and connected to, and contrasted with, their Hegelian origin. While scholars of nineteenth-century philosophy may find some value in re-envisioning the development of continental thought through Stewart's narrative [End Page 330] (especially insofar as it challenges unfortunate caricatures of the history of ideas), the target audiences of Hegel's Century are advanced students of philosophy and the general public of interested persons. Though this approach has its shortcomings, it is nevertheless a valuable addition to the literature. Not only does Stewart tell a compelling story about the trajectory of nineteenth-century philosophy, but he also connects this conceptual evolution to shifts in political, economic, literary, and religious history. As such, Hegel's Century is best thought of as a gateway text for students and autodidacts fascinated by the philosophical bases for a century of upheaval and revolution.Following a general introduction, Stewart divides the book into three parts, each more substantive than the last. His introduction does the necessary legwork detailing the purpose, audience, and strategy of the book. Its most philosophically interesting aspect is the outline of seven ideas Stewart hopes will reform the reception of nineteenth-century philosophy in the modern classroom. Philosophical exposition begins in part 1, which consists of two chapters wherein Stewart details those aspects of Hegel's philosophy that will be most thoroughly thematized throughout the book. These ideas are largely sourced from specific portions of Hegel's Phenomenology of Spirit, Lectures on the Philosophy of Religion, and Lectures on the Philosophy of History. Chapter 1 focuses on Hegel's view of alienation in the Phenomenology, especially the (in)famous section on the master and bondsman. In chapter 2, Stewart explains Hegel's conception of Christianity and the nature of divinity. Stewart maintains that as a result of dense prose and conceptual rigor, Hegel's religious views were open to myriad ambiguous interpretations. When Stewart turns to "first-generation" thinkers, namely, those who attended Hegel's lectures in Berlin and were a direct part of the intoxicating intellectual atmosphere that spread therein, questions concerning the essence of Christianity (as Feuerbach's magnum opus suggests) are front and center. Stewart's cursory account of Hegel's theory of Christianity serves adequately as the background for contextualizing this intellectual drama.In part 2, three of these "first-generation" thinkers are given their own chapters: Heine (chapter 3), Feuerbach (chapter 4), and Bauer (chapter 5). In each case, the chapter starts with a short intellectual biography focusing on the formative role Hegel played in the thinker's development. This is followed by a sustained discussion of a few central texts and interspersed analyses of how Hegel's influence is felt therein. Stewart's discussion often shows the ambivalence with which each of these thinkers handled their Hegelian inheritance. Though the specifics differ, each of these three thinkers took Hegelian theory to a more radical limit than Hegel himself did. The chapters on Heine and Bauer—figures usually overlooked in survey courses—are admirable introductions for the interested neophyte.In part 3, Stewart shows Hegel's tentacles extending throughout the latter half of the nineteenth century, notwithstanding the Hegelians' difficulty in acquiring academic posts. The political and religious radicalism of first-generation critics bleeds into the formative development of the so-called "second generation" of thinkers: Marx... (shrink)

The claim is that some collective entities can be thought of as part of the moral realm by virtue of their status as objects of moral concern. Collectivities are defined in terms of irreducibly corporate action and distinctive conditions of persisting identity. Their lack of sentience does not preclude moral concern, and their raison d'être may render moral concern for them appropriate. Recent attempts by Pettit, McMahon, and Broome to limit the moral realm to individuals are considered. They are rebutted (...) on the grounds that they rest heavily on pre-existing moral intuitions; they ascribe a stronger thesis than is necessary to the sponsors of the moral significance of non-individuals; and they wrongly assume that what has value for individuals must have value because it has value for individuals. Collectivities can have moral importance even if they lack the intrinsic moral importance attaching to human beings, and substantial consequences follow from that fact. In particular, routine appeals to the distinctness of persons become more problematic when collectivities, themselves composed entirely of persons, have independent moral significance which needs to be taken into account. That will affect both assessment of moral consequences and the process of moral decision-making. (shrink)
