‘Fake news’ has become an increasingly common refrain in public discourse, though the term itself has several uses, at least one of which constitutes Frankfurtian bullshit. After examining what sorts of fake news appeals do and do not count as bullshit, I discuss strategies for overcoming our openness to such bullshit. I do so by drawing a parallel between openness to bullshit and naïve skepticism—one’s willingness to reject the concept of truth on unsupported or ill-considered grounds—and suggest that (...) this parallel indicates three principles for how we ought to combat our openness to fake news and other bullshit. First, the root causes of bullshit openness are not monolithic; we should adopt anti-bullshit strategies in recognition of this fact. Second, our efforts to overcome bullshit openness should be collaborative efforts to create an environment that allows for sustained interrogation of our bullshit openness, rather than a confrontational provision of contrary evidence, despite the fact that such strategies are more time-intensive. Third, social media is unlikely to be a fertile ground on which we will make meaningful progress in the fight against bullshit because of the inherent nature of social media platforms as spaces for short, declarative, confrontational claims.

Introductory students regularly endorse naïve skepticism—unsupported or uncritical doubt about the existence and universality of truth—for a variety of reasons. Though some of the reasons for students’ skepticism can be traced back to the student—for example, a desire to avoid engaging with controversial material or a desire to avoid offense—naïve skepticism is also the result of how introductory courses are taught, deemphasizing truth to promote students’ abilities to develop basic disciplinary skills. While this strategy has (...) a number of pedagogical benefits, it prevents students in early stages of intellectual development from understanding truth as a threshold concept. Using philosophy as a case study, I argue that we can make progress against naïve skepticism by clearly discussing how metadisciplinary aims differ at the disciplinary and course levels in a way that is meaningful, reinforced, and accessible.

Epistemic contextualists like David Lewis allow that we have substantially infallibilist reflective intuitions about knowledge even though our everyday talk accepts fallibilist attributions of knowledge. They give serious weight to both our everyday talk and our propensity to assent to the skeptic's conclusions, and give us a concept of knowledge that accommodates both. The skeptic would, of course, leverage such infallibilist intuitions in order to undermine the legitimacy of our everyday attributions. Most contemporary epistemologists would simply argue that our concept (...) of knowledge is fallibilist, but this doesn't give them a particularly convincing reply to intuitively compelling skeptical arguments. ;This essay, most generally, takes up the question of how best to argue about skepticism. I claim that a philosophical account of knowledge that responds to skepticism should be able to clearly accommodate our epistemic agency. In chapter 1 I explain how skepticism challenges our naIve conception of agency and introduce two criteria for an adequate response to skepticism. In chapter 2, I discuss contextualist solutions; I argue they fail to satisfy our criteria and fail on their own terms; I explain how both failures relate to a failure to adequately treat epistemic agency. In chapter 3 I develop a conception of epistemic agency that describes what it is to be an active, reasoning source of belief. This picture is at odds with a dominant strain of epistemology that has it that one is substantially subject to belief, not effectively responsible for it; I criticize an influential argument by Bernard Williams that claims belief is not an attitude we control. This discussion in chapter 3 gives support to, a rationale for, the anti-insulationism requirement set out in chapter 1. Finally, in chapter 4 I return to the methodological issues of how to argue about skepticism. I first defend the idea that a knowledge-based skepticism is worth philosophical attention. I then offer an interpretation of what the skeptic is up to, and discuss what an effective counterstrategy might look like; I suggest that a particular sort of normative argument is the best way with the skeptic.

A perceptual realism that is naive in a good way must be naively realistic about world and mind. But contemporary self-described naive realists often have trouble acknowledging that both the good cases of successful perception and the bad cases of illusion and hallucination involve internal experiential states with intentional contents that present the world as being a certain way. They prefer to think about experience solely in relational terms because they worry that otherwise we won’t be able to escape from (...) radical skepticism. I argue that experiential relations to objects require that their subjects be in internal experiential states. But this does not mean that these states are our epistemological starting point which can be known independently of any knowledge of the external world. We do escape the epistemological predicament of radical skepticism because the good cases are primary over the bad ones. But this is not because the good cases alone provide reasons for belief, but because we do not need a reason to think we are in a good case, but do need a reason to think we are not, and such a reason must come from a good case. So bad cases can only be thought of as deviations from good cases. And we can only understand experiences as states with contents distinct from their objects and present in good and bad cases once we understand misrepresentation, that is, bad cases, and therefore only as we ascribe knowledge of the external world to ourselves.

Many philosophers are skeptical about disjunctivism —a theory of perceptual experience which holds roughly that a situation in which I see a banana that is as it appears to me to be and one in which I have a hallucination as of a banana are mentally completely different. Often this skepticism is rooted in the suspicion that such a view cannot adequately account for the bad case—in particular, that such a view cannot explain why what it’s like to have (...) a hallucination can be exactly like what it’s like to have a veridical experience, that it cannot explain why the hallucination I have in the bad case is subjectively indistinguishable from the kind of experience I have in the good case, and that it cannot offer a viable account of the nature of hallucination. -/- In this paper, I argue that a proper formulation of disjunctivism can avoid these objections. Disjunctivism should be formulated as the weakest claim required to preserve its primary motivation, viz., Naïve Realism—the view that veridical experience fundamentally consists in the subject perceiving entities in her environment. And the weakest claim required to preserve Naïve Realism allows for many sorts of commonalities across the good and hallucinatory cases, commonalities that can be marshaled in responding to the objections. Most importantly, disjunctivism properly formulated is compatible with “positive” accounts of the nature of hallucination. (shrink)

Dogmatism holds that an experience or seeming that p can provide prima facie immediate justification for believing p in virtue of its phenomenology. Dogmatism about perceptual justification has appealed primarily to proponents of representational theories of perceptual experience. Call dogmatism that takes perceptual experience to be representational "representational phenomenal dogmatism." As we show, phenomenal seemings play a crucial role in dogmatism of this kind. Despite its conventional appeal to representational theorists, dogmatism is not by definition committed to any particular view (...) of perceptual experience. Naive realists and disjunctivists who hold that perceptual experience is a perceptual relation of direct acquaintance can also endorse dogmatism. Indeed, we argue that they ought to do so. Otherwise, they cannot maintain that relationalism about perceptual experience has an epistemic advantage compared to the representational view. We then show that even if we grant that relationalism has this advantage, only dogmatism that takes perceptual experience to be representational can be extended to account for non-deductive inferential justification. As an account of the latter is required to avoid succumbing to skepticism, relationalism, we argue, does not have the epistemic advantage its defenders claim it has. (shrink)

Abstract. The dissertation defends the thesis that the mind-body problem arises against the background of the elimination of the manifest physical world, and that the only satisfactory response to it is to take back that elimination and thus to dissolve the problem. Various materialist and dualist responses are shown to be inadequate. They are only different forms of ontological fundamentalism – physics fundamentalism and consciousness fundamentalism – that lead to ultimately meaningless metaphysical constructions. By contrast, on the ontologically pluralist view (...) outlined here, the fact that the entire spatiotemporal world has a physical microstructure is compatible with a naive realism with regard to both the manifest physical world and to consciousness. We only need to ascribe physical microstructures to both while identifying neither with these structures. After an introduction that identifies the elimination of the manifest physical world in modernity as the metaphysical background of the mind-body problem and describes the dilemmatic situation created by the typical reactions to it, the first chapter attempts to clarify what consciousness is. The second chapter then discusses some of the standard formulations of the so-called “puzzle” or “mystery” of consciousness. It is shown that these cannot be transformed into a genuine, answerable question. The notion that other macrophenomena can be explained much better than consciousness, perhaps even in a completely transparent way, is revealed to be an illusion, an artefact of the tacit elimination of the manifest physical world. In the third chapter, the thesis that consciousness has spatial properties is defended against various forms of skepticism. The fourth chapter begins the debate with the mind-body identity theory by discussing various positions on identity statements in the philosophy of language. This discussion leads to the conclusion that the idea of informative identity statements is meaningless. On this basis, the notion of an empirically contentful so-called “scientific identification” of consciousness phenomena with their neuronal correlates is criticized in the fifth chapter. The sixth chapter argues that it is possible to dissolve the problem of mental causation if a physiological and ultimately also a microphysical structure is ascribed to consciousness. In a concluding reflection it is explained what it means that the present suggestion amounts to a dissolution rather than a solution of the traditional mind-body problem. Zusammenfassung. In dieser Arbeit wird die These vertreten, dass das Leib-Seele- Problem vor dem Hintergrund der Elimination der manifesten physischen Welt entsteht und die einzig befriedigende Reaktion darauf nur sein kann, diese Elimination wieder rückgängig zu machen und das Problem damit aufzulösen. Materialistische und dualistische Reaktionen werden als unzulänglich erwiesen. Sie sind nur verschiedene Formen eines ontologischen Fundamentalismus – Physikfundamentalismus und Bewusstseinsfundamentalismus – der zu letztlich sinnlosen metaphysischen Konstruktionen führt. Dagegen ist nach dem hier vertretenen ontologischen Pluralismus die Tatsache, dass die gesamte raumzeitliche Welt eine physikalische Mikrostruktur hat, mit einem naiven Realismus sowohl in Bezug auf die manifeste physische Welt als auch in Bezug auf das Bewusstsein vereinbar. Wir müssen nur beiden eine physikalische Mikrostruktur zuschreiben ohne sie mit dieser zu idenfizieren. Nachdem in der Einleitung die Elimination der manifesten physischen Welt in der Neuzeit als der metaphysische Hintergrund des Leib-Seele-Problems identifiziert und die durch die typischen Reaktionen darauf entstehende dilemmatische Aus- gangssituation beschrieben worden ist, klärt das erste Kapitel, was Bewusstsein ist. Im zweiten Kapitel werden dann einige gängige Formulierungen des so genannten „Bewusstseinsrätsels“ vorgestellt. Es wird gezeigt, dass diese sich nicht in eine wirklich beantwortbare Frage transformieren lassen. Die Vorstellung, dass sich andere Makrophänomene wesentlich besser erklären lassen als das Bewusstsein, oder gar in vollständig transparenter Weise, wird als Illusion, als Artefakt der stillschweigenden Elimination der manifesten Welt erwiesen. Im dritten Kapitel wird die These, dass das Bewusstsein räumliche Eigenschaften hat, gegen verschiedene Formen der Skepsis verteidigt. Im vierten Kapitel beginnt die Auseinandersetzung mit der Identitätstheorie mit einer Diskussion sprachphilosophischer Positionen zu Identitätsaussagen, die die These begründet, dass die Vorstellung informativer Identitätsaussagen sinnlos ist. Auf dieser Grundlage wird im fünften Kapitel die Vorstellung einer empirisch gehaltvollen so genannten „wissenschaftlichen Identifikation“ von Bewusstseinsphänomenen mit ihren neuronalen Korrelaten kritisiert. Im sechsten Kapitel wird gezeigt, dass sich das Problem mentaler Verursachung auflösen lässt, wenn man Bewusstseinsphänomenen eine physiologische und letztlich auch physikalische Mikrostruktur zuschreibt. In einer Schlussbetrachtung wird erläutert, warum der Vorschlag in dieser Arbeit eine Auflösung statt einer Lösung des Leib-Seele-Problems darstellt. (shrink)

An overview of the import of disjunctivism to the problem of radical scepticism is offered. In particular, the disjunctivist account of perceptual experience is set out, along with the manner in which it intersects with related positions such as naïve realism and intentionalism, and it is shown how this account can be used to a motivate an anti-sceptical proposal. In addition, a variety of disjunctivism known as epistemological disjunctivism is described, and it is explained how this proposal offers a (...) further way of responding to radical scepticism.

Gila Sher approaches knowledge from the perspective of the basic human epistemic situation—the situation of limited yet resourceful beings, living in a complex world and aspiring to know it in its full complexity. What principles should guide them? Two fundamental principles of knowledge are epistemic friction and freedom. Knowledge must be substantially constrained by the world (friction), but without active participation of the knower in accessing the world (freedom) theoretical knowledge is impossible. This requires a grounding of all knowledge, empirical (...) and abstract, in both mind and world, but the fall of traditional foundationalism has led many to doubt the viability of this ‘classical’ project. Sher challenges this skepticism, charting a new foundational methodology, foundational holism, that differs from others in being holistic, world-oriented, and universal (i.e., applicable to all fields of knowledge). Using this methodology, Epistemic Friction develops an integrated theory of knowledge, truth, and logic. This includes (i) a dynamic model of knowledge, incorporating some of Quine’s revolutionary ideas while rejecting his narrow empiricism, (ii) a substantivist, non-traditional correspondence theory of truth, and (iii) an outline of a joint grounding of logic in mind and world. The model of knowledge subjects all disciplines to demanding norms of both veridicality and conceptualization. The correspondence theory is robust and universal yet not simplistic or naive, admitting diverse forms of correspondence. Logic’s grounding in the world brings it in line with other disciplines while preserving, and explaining, its strong formality, necessity, generality, and normativity. (shrink)

Studies in the psychology of visual expertise have tended to focus on a limited set of expert domains, such as radiology and athletics. Conclusions drawn from these data indicate that experts use parafoveal vision to process images holistically. In this study, we examined a novel, as-of-yet-unstudied class of visual experts—architects—expecting similar results. However, the results indicate that architects, though visual experts, may not employ the holistic processing strategy observed in their previously studied counterparts. Participants (n = 48, 24 architects, 24 (...) naïve) were asked to find targets in chest radiographs and perspective images. All images were presented in both gaze-contingent and normal viewing conditions. Consistent with a holistic processing model, we expected two results: (1) architects would display a greater difference in saccadic amplitude between the gaze- contingent and normal conditions, and (2) architects would spend less time per search than an undergraduate control group. We found that the architects were more accurate in the perspectival task, but they took more time and displayed a lower difference in saccadic amplitude than the controls. Our research indicates a disjunctive conclusion. Either architects are simply different kinds of visual experts than those previously studied, or we have generated a task that employs visual expertise without holistic processing. Our data suggest a healthy skepticism for across-the-board inferences collected from a single domain of expertise to the nature of visual expertise generally. More work is needed to determine whether holism is a feature of all visual expertise. (shrink)

It seems possible to see a star that no longer exists. Yet it also seems right to say that what no longer exists cannot be seen. We therefore face a puzzle, the traditional answer to which involves abandoning naïve realism in favour of a sense datum view. In this article, however, I offer a novel exploration of the puzzle within a naïve realist framework. As will emerge, the best option for naïve realists is to embrace an eternalist (...) view of time, and claim that in the relevant case, one sees a still existent star‐stage located somewhere in the distant past.

Relationalism maintains that perceptual experience involves, as part of its nature, a distinctive kind of conscious perceptual relation between a subject of experience and an object of experience. Together with the claim that perceptual experience is presentational, relationalism is widely believed to be a core aspect of the naive realist outlook on perception. This is a mistake. I argue that naive realism about perception can be upheld without a commitment to relationalism.

Unconscious perceptions have recently become a focal point in the debate for and against naive realism. In this paper I defend the naive realist side. More specifically, I use an idea of Martin’s to develop a new version of naive realism—neuro-computational naive realism. I argue that neuro-computational naive realism offers a uniform treatment of both conscious and unconscious perceptions. I also argue that it accommodates the possibility of phenomenally different conscious perceptions of the same items, and that it can answer (...) a further challenge to naive realism raised by Berger and Nanay.

This paper argues for the conjunctive thesis of naïve realism and phenomenal intentionalism about perceptual experiences. Naïve realism holds that the phenomenology of veridical perceptual experience is constituted by environmental objects that the subject perceives. Phenomenal intentionalism about perceptual experience states that perceptual experience has intentionality in virtue of its phenomenology. I first argue that naïve realism is not incompatible with phenomenal intentionalism. I then argue that phenomenal intentionalists can handle two objections to it by adopting (...) class='Hi'>naïve realism: the first objection is that phenomenal intentionalism cannot explain how a veridical perceptual experience is directed at a particular object rather than any other object of the same kind. The second objection is that phenomenal intentionalism cannot explain how a perceptual experience is directed at a type of external object rather than other types of objects without appealing to a resemblance relation between a perceptual experience and an external object, which is considered to be problematic.

In a recent paper, Berger and Nanay consider, and reject, three ways of addressing the phenomenon of unconscious perception within a naïve realist framework. Since these three approaches seem to exhaust the options open to naïve realists, and since there is said to be excellent evidence that perception of the same fundamental kind can occur, both consciously and unconsciously, this is seen to present a problem for the view. We take this opportunity to show that all three approaches (...) considered remain perfectly plausible ways of addressing unconscious perception within a naïve realist framework. So far from undermining the credibility of naïve realism, Berger and Nanay simply draw our attention to an important question to be considered by naïve realists in future work. Namely, which of the approaches considered is most likely to provide an accurate account of unconscious perception in each of its purported incarnations? (shrink)

Karl Pfeifer attempts to present a coherent view of panentheism that eschews Pickwickian senses of “in” and aligns itself with, and builds upon, familiar diagrammed portrayals of panentheism. The account is accordingly spatial-locative and moreover accepts the proposal of R.T. Mullins that absolute space and time be regarded as attributes of God. In addition, however, it argues that a substantive parthood relation between the world and God is required. Pfeifer’s preferred version of panpsychism, viz. panintentionalism, is thrown into the mix (...) as an optional add-on. On this account, God is conceived of as a “spiritual field” whose nature can be made more intelligible by regarding “God” as having a mass-noun sense in some contexts. Pfeifer closes with the suggestion that we look to topology and mereology for further development of the position outlined in his paper. (shrink)

I begin by describing what I call simple naïve realism. Then I describe relevant empirical results. Next, I develop two new empirical arguments against simple naive realism. Then I briefly look at two new, more complex forms of naïve realism: one due to Keith Allen and the other due to Heather Logue and Ori Beck. I argue that they are not satisfactory retreats for naive realists. The right course is to reject naive realism altogether. My stalking horse is (...) contemporary naive realism but there is a larger, positive lesson: new empirical results support a brain-based theory of sensory consciousness. (shrink)

Different authors offer subtly different characterizations of naïve realism. We disentangle the main ones and argue that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve per- ceptual error. We assess two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and conclude that they fail. Another lead- ing attempt is assessed in a companion paper, which also sketches an alternative (...) representational account. (shrink)

Early twentieth-century philosophers of perception presented their naïve realist views of perceptual experience in anti-Kantian terms. For they took naïve realism about perceptual experience to be incompatible with Kant’s claims about the way the understanding is necessarily involved in perceptual consciousness. This essay seeks to situate a naïve realist account of visual experience within a recognisably Kantian framework by arguing that a naïve realist account of visual experience is compatible with the claim that the understanding is (...) necessarily involved in the perceptual experience of those rational beings with discursive intellects. The resultant view is middle way between recent conceptualist and non-conceptualist interpretations of Kant, holding that the understanding is necessarily involved in the kind of perceptual consciousness that we, as rational beings, enjoy whilst allowing that the relations of apprehension which constitute perceptual consciousness are independent of acts of the understanding.

Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist (...) views cannot account for the generality of visual experiences, and that the naïve realist explanation of particularity has unacceptable implications for self- knowledge: the knowledge we have of the character of our own experiences. We argue in this paper that neither claim is correct: naïve realism can explain the generality of experiences, and the naïve realist explanation of particularity raises no problems for our self-knowledge. (shrink)

It has been claimed that naïve realism predicts phenomenological similarities where there are none and, thereby, mischaracterises the phenomenal character of perceptual experience. If true, this undercuts a key motivation for the view. Here, we defend naïve realism against this charge, proposing that such arguments fail (three times over). In so doing, we highlight a more general problem with critiques of naïve realism that target the purported phenomenological predictions of the view. The problem is: naïve realism, (...) broadly construed, doesn’t make phenomenological predictions of the required sort. So, as a result, opponents must resign themselves to attacking specific incarnations of naïve realism, or approach matters quite differently. (shrink)

Naïve Realists think that the ordinary mind-independent objects that we perceive are constitutive of the character of experience. Some understand this in terms of the idea that experience is diaphanous: that the conscious character of a perceptual experience is entirely constituted by its objects. My main goal here is to argue that Naïve Realists should reject this, but I’ll also highlight some suggestions as to how Naïve Realism might be developed in a non-diaphanous direction.

It is well-known that naïve realism has difficulty accommodating perceptual error. Recent discussion of the issue has focused on whether the naïve realist can accommodate hallucination by adopting disjunctivism. However, illusions are more difficult for the naïve realist to explain precisely because the disjunctivist solution is not available. I discuss what I take to be the two most plausible accounts of illusion available to the naïve realist. The first claims that illusions are cases in which you (...) are prevented from perceiving properties you would ordinarily perceive and subsequently form a mistaken judgment about the perceived object. The second appeals to an unusual look or appearance that the perceived object instantiates. I argue that neither account is satisfactory and that, consequently, naïve realism ought to be rejected. (shrink)

Recently, it has been objected that naïve realism is inconsistent with an empirically well-supported claim that mental states of the same fundamental kind as ordinary conscious seeing can occur unconsciously (SFK). The main aim of this paper is to establish the following conditional claim: if SFK turns out to be true, the naïve realist can and should accommodate it into her theory. Regarding the antecedent of this conditional, I suggest that empirical evidence renders SFK plausible but not obvious. (...) For it is possible that what is currently advocated as unconscious perception of the stimulus is in fact momentaneous perceptual awareness (or residual perceptual awareness) of the stimulus making the subject prone to judge in some way rather than another, or to act in some way rather than another. As to the apodosis, I show that neither the core of naïve realism nor any of its main motivations is undermined if SFK is assumed. On the contrary, certain incentives for endorsing naïve realism become more tempting on this assumption. Since the main motivations for naïve realism retain force under SFK, intentionalism is neither compulsory nor the best available explanation of unconscious perception. (shrink)

This paper applies speech-act theory to craft a new response to Pyrrhonian skepticism and diagnose its appeal. Carefully distinguishing between different levels of language-use and noting their interrelations can help us identify a subtle mistake in a key Pyrrhonian argument.

Perceptual experience has representational content. My argument for this claim is an inference to the best explanation. The explanandum is cognitive penetration. In cognitive penetration, perceptual experiences are either causally influenced, or else are partially constituted, by mental states that are representational, including: mental imagery, beliefs, concepts and memories. If perceptual experiences have representational content, then there is a background condition for cognitive penetration that renders the phenomenon prima facie intelligible. Naïve realist or purely relational accounts of perception leave (...) cognitive penetration less well-explained, even when formulated with so-called ‘standpoints’ or ‘third relata.’. (shrink)

In this chapter, I present and explore various arguments for skepticism that are related to memory. My focus will be on the aspects of the arguments that are unique to memory, which are not shared, for example, by the more often explored skeptical arguments related to perception. -/- Here are some interesting upshots. First, a particular problem for justifiably concluding that one's memory is reliable is that any reasoning in favor of this conclusion will either result in epistemically circularity (...) or not be sufficient to justify the conclusion. Second, since many beliefs stored in memory do not appear to be based on evidence, it might also appear to follow that they are not justified. Third, although many stored memory beliefs are not based on stored memory experiences in the same way that perceptual beliefs are based on perceptual experiences, skeptical scenarios loom just as problematically for memory beliefs as they do for perceptual beliefs.

This paper elaborates on an argument in my book *Perception*. It has two parts. In the first part, I argue against what I call "basic" naive realism, on the grounds that it fails to accommodate what I call "internal dependence" and it requires an empirically implausible theory of sensible properties. Then I turn Craig French and Ian Phillips’ modified naïve realism as set out in their recent paper "Austerity and Illusion". It accommodates internal dependence. But it may retain the (...) empirically implausible theory of sensible properties. And it faces other empirical problems. Representationalism about experiences avoids those problems and is to be preferred. (shrink)

This paper sets out a novel response to the ‘screening off problem’ for naïve realism. The aim is to resist the claim (which many naïve realists accept) that the kind of experience involved in hallucinating also occurs during perception, by arguing that there are causal constraints that must be met if an hallucinatory experience is to occur that are never met in perceptual cases. Notably, given this response, it turns out that, contra current orthodoxy, naïve realists need (...) not adopt any particular view about the psychological nature of hallucinatory experience to handle the screening off problem. Consequently, room opens up for naïve realists to endorse whatever theory of hallucinatory experience seems to best capture the distinctive nature of such episodes. (shrink)

A common response to radical skeptical challenges to our knowledge of the external world has been that there are explanatory reasons (e.g., simplicity, coherence, explanatory power, conservatism) for favoring commonsense explanations of our sensory experiences over skeptical explanations. Despite the degree of visibility this class of response has enjoyed, it has often been viewed with skepticism [sic] by the epistemological community because of concerns about the epistemic merits of explanatory reasoning. I argue that skeptical challenges that employ skeptical hypotheses (...) presuppose central explanationist tenets and that this fact should raise one’s estimation of the strength of explanationist responses to skepticism. (shrink)

Much of the discussion of Naive Realism about veridical experience has focused on a consequence of adopting it—namely, disjunctivism about perceptual experience. However, the motivations for being a Naive Realist in the first place have received relatively little attention in the literature. In this paper, I will elaborate and defend the claim that Naive Realism provides the best account of the phenomenal character of veridical experience.

This paper develops the idea that valid arguments are equivalent to true conditionals by combining Kripke’s theory of truth with the evidential account of conditionals offered by Crupi and Iacona. As will be shown, in a first-order language that contains a naïve truth predicate and a suitable conditional, one can define a validity predicate in accordance with the thesis that the inference from a conjunction of premises to a conclusion is valid when the corresponding conditional is true. The validity (...) predicate so defined significantly increases our expressive resources and provides a coherent formal treatment of paradoxical arguments. (shrink)

Naive realists hold that experience is to be understood in terms of an intimate perceptual relation between a subject and aspects of the world, relative to a certain standpoint. Those aspects of the world themselves shape the contours of consciousness. But blurriness is an aspect of some of our experiences that does not seem to come from the world. I argue that this constitutes a significant challenge to some forms of naive realism. But I also argue that there is a (...) robust form of naive realism which is unfazed by the blurriness of some of our experiences, even when that blurriness is understood as a subjective modification of consciousness.

Skepticism about the internal world is actually more troubling than skepticism about the external world.

Abstract Timothy Williamson has recently proposed to undermine modal skepticism by appealing to the reducibility of modal to counterfactual logic ( Reducibility ). Central to Williamson’s strategy is the claim that use of the same non-deductive mode of inference ( counterfactual development , or CD ) whereby we typically arrive at knowledge of counterfactuals suffices for arriving at knowledge of metaphysical necessity via Reducibility. Granting Reducibility, I ask whether the use of CD plays any essential role in a Reducibility-based (...) reply to two kinds of modal skepticism. I argue that its use is entirely dispensable, and that Reducibility makes available replies to modal skeptics which show certain propositions to be metaphysically necessary by deductive arguments from premises the modal skeptic accepts can be known.

The epistemological debate about radical skepticism has focused on whether our beliefs in apparently obvious claims, such as the claim that we have hands, amount to knowledge. Arguably, however, our concept of knowledge is only one of many knowledge-like concepts that there are. If this is correct, it follows that even if our beliefs satisfy our concept of knowledge, there are many other relevantly similar concepts that they fail to satisfy. And this might give us pause. After all, we (...) might wonder: What is so great about the concept of knowledge that we happen to have? Might it be more important, epistemically speaking, to investigate whether our beliefs satisfy some other relevantly similar concept instead? And how should questions such as these even be understood? This paper discusses the epistemological significance of these issues. In particular, a novel skeptical stance called ‘meta-skepticism’ is introduced, which is a kind of skepticism about the idea that some knowledge-like concepts are epistemically more important than others. It suggested that it is unclear whether this form of skepticism can be avoided. (shrink)

Counterfactual skepticism says that most ordinary counterfactuals are false. While few endorse counterfactual skepticism, the precise costs of the view are disputed and not generally well-understood. I have two aims in this paper. My first and primary aim is to establish, on grounds acceptable to all parties, that counterfactual skepticism is not benign. I argue it leads to significant skepticism about the future: if counterfactual skepticism is true, then we can have only very limited knowledge (...) about the future. I give three arguments to this conclusion, taking as premises principles connecting knowledge of indicative conditionals to knowledge of disjunctions; and principles linking knowledge of indicative conditionals to knowledge of counterfactual conditionals.My second aim is to examine the consequences for non-skeptical theories. My arguments indicate that not only are many ordinary counterfactuals true, but that we also know them. How can this be reconciled with the very real tension between counterfactuals and chance? I consider two solutions, one purely epistemic and one contextualist. Together they suggest something like contextualism about knowledge is required to fully resolve the skeptical threat. (shrink)

Empirical work on motivated reasoning suggests that our judgments are influenced to a surprising extent by our wants, desires and preferences (Kahan 2016; Lord, Ross, and Lepper 1979; Molden and Higgins 2012; Taber and Lodge 2006). How should we evaluate the epistemic status of beliefs formed through motivated reasoning? For example, are such beliefs epistemically justified? Are they candidates for knowledge? In liberal democracies, these questions are increasingly controversial as well as politically timely (Beebe et al. 2018; Lynch forthcoming, 2018; (...) Slothuus and de Vreese 2010). And yet, the epistemological significance of motivated reasoning has been almost entirely ignored by those working in mainstream epistemology. We aim to rectify this oversight. Using politically motivated reasoning as a case study, we show how motivated reasoning gives rise to three distinct kinds of skeptical challenges. We conclude by showing how the skeptical import of motivated reasoning has some important ramifications for how we should think about the demands of intellectual humility. (shrink)

There are many different oughts. There is a moral ought, a prudential ought, an epistemic ought, the legal ought, the ought of etiquette, and so on. These oughts can prescribe incompatible actions. What I morally ought to do may be different from what I self-interestedly ought to do. Philosophers have claimed that these conflicts are resolved by an authoritative ought, or by facts about what one ought to do simpliciter or all-things-considered. However, the only coherent notion of an ought simpliciter (...) has preposterous first-order normative commitments. It is more reasonable to reject the ought simpliciter in favor of the form of normative pluralism advocated in (Tiffany 2007). (shrink)

Beall and Murzi :143–165, 2013) introduce an object-linguistic predicate for naïve validity, governed by intuitive principles that are inconsistent with the classical structural rules. As a consequence, they suggest that revisionary approaches to semantic paradox must be substructural. In response to Beall and Murzi, Field :1–19, 2017) has argued that naïve validity principles do not admit of a coherent reading and that, for this reason, a non-classical solution to the semantic paradoxes need not be substructural. The aim of (...) this paper is to respond to Field’s objections and to point to a coherent notion of validity which underwrites a coherent reading of Beall and Murzi’s principles: grounded validity. The notion, first introduced by Nicolai and Rossi, is a generalisation of Kripke’s notion of grounded truth, and yields an irreflexive logic. While we do not advocate the adoption of a substructural logic, we take the notion of naïve validity to be a legitimate semantic notion that points to genuine expressive limitations of fully structural revisionary approaches.

W dziełach Arystotelesa, lub z medievals, jak również w pismach późniejszych zdroworozsądkowe filozofów, takich jak Thomas Reid czy GE Moore’a, możemy znaleźć rodzinę różnych prób uporania się ze strukturami rozsądku i wspólnego -sense świat, który jest nam dany w normalnym, doświadczenie pre-teoretycznym. Będziemy argumentować, co wynika, że ​​teoria takich struktur stanowi ważny i dotychczas niedoceniany związek między wczesnym psychologii Gestalt z jednej strony, oraz współczesnych osiągnięć w filozofii i sztucznej inteligencji badań na innych.

Neo-Russellians like Salmon and Braun hold that: the semantic contents of sentences are structured propositions whose basic components are objects and properties, names are directly referential terms, and a sentence of the form ‘n believes that S’ is true in a context c iff the referent of the name n in c believes the proposition expressed by S in c. This is sometimes referred to as ‘the Naive Russellian theory’. In this talk, I will discuss the Naive Russellian theory primarily (...) in connection with a problem known as Schiffer’s puzzle. Schiffer first presented the puzzle as an argument against the Naive Russellian theory. Schiffer’s argument proceeds in two steps. In step one, Schiffer argues that the Naive Russellian theory is committed to two principles regarding de re belief; the special-case consequence and Frege’s constraint. Then, in step two, Schiffer argues that the special-case consequence is not consistent with Frege’s constraint. Salmon and Braun reply to Schiffer’s argument that although the Naive Russellian theory is committed to Frege’s constraint, it is not committed to the special-case consequence. However, in this paper, I will argue with a new Schiffer-case that even if the Naive Russellian theory is not committed to the special-case consequence, it is still not consistent with Frege’s constraint. Concluding, I will discuss the possibility to reject Frege’s constraint within the Naive Russellian theory. (shrink)

This article proposes a way of doing type theory informally, assuming a cubical style of reasoning. It can thus be viewed as a first step toward a cubical alternative to the program of informalization of type theory carried out in the homotopy type theory book for dependent type theory augmented with axioms for univalence and higher inductive types. We adopt a cartesian cubical type theory proposed by Angiuli, Brunerie, Coquand, Favonia, Harper, and Licata as the implicit foundation, confining our presentation (...) to elementary results such as function extensionality, the derivation of weak connections and path induction, the groupoid structure of types, and the Eckmman–Hilton duality.

Rejecting the Cut rule has been proposed as a strategy to avoid both the usual semantic paradoxes and the so-called v-Curry paradox. In this paper we consider if a Cut-free theory is capable of accurately representing its own notion of validity. We claim that the standard rules governing the validity predicate are too weak for this purpose and we show that although it is possible to strengthen these rules, the most obvious way of doing so brings with it a serious (...) problem: an internalized version of Cut can be proved for a Curry-like sentence. We also evaluate a number of possible ways of escaping this difficulty. (shrink)

Skepticism is one of the most enduring and profound of philosophical problems. With its roots in Plato and the Sceptics to Descartes, Hume, Kant and Wittgenstein, skepticism presents a challenge that every philosopher must reckon with. In this outstanding collection philosophers engage with skepticism in five clear sections: the philosophical history of skepticism in Greek, Cartesian and Kantian thought; the nature and limits of certainty; the possibility of knowledge and related problems such as perception and the (...) debates between objective knowledge and constructivism; the transcendental method as a response to skepticism and the challenge of naturalism; overcoming the skeptical challenge.

This paper outlines a new type of skepticism that is both compatible with fallibilism and supported by work in psychology. In particular, I will argue that we often cannot properly trust our ability to rationally evaluate reasons, arguments, and evidence (a fundamental knowledge-seeking faculty). We humans are just too cognitively impaired to achieve even fallible knowledge, at least for many beliefs.

A new kind of skepticism about philosophy is articulated and argued for. The key premise is the claim that many of us are well aware that in the past we failed to have good responses to substantive objections to our philosophical beliefs. The conclusion is disjunctive: either we are irrational in sticking with our philosophical beliefs, or we commit some other epistemic sin in having those beliefs.
