This thesis is a defense of (a version of) moral perceptualism. Moral perceptualism (MP), as is generally understood, advocates the bold view that “moral properties can be perceptual content”; its supporters include Audi (2013, 2015), Lord (2018), McNaughton (1988), McBrayer (2010a, 2010b), Cowan (2015), and Werner (2016, 2020b). In support of MP, Werner (2016) bolsters what he calls ‘phenomenal contrast arguments(PCAs)’. According to PCAs, the best explanation for inter-subjective phenomenal contrast between two subjects facing the same moral situation is that (...) one subject has moral perceptual experience(s) of moral properties, whereas the other does not. If PCAs are sound, then MP can be justified (in that one subject does perceive moral properties). However, some powerful counterarguments against MP have been proposed by Väyrynen(2018), Reiland(2021), and Chudnoff(2015); each of them provides competing explanations for inter-subjective phenomenal contrast and argues that their explanations are more reasonable than PCAs. My purposes in this thesis are to ascertain (I) which explanation for inter-subjective phenomenal contrast is more reasonable; (II) (how) could moral perceptualists like Werner (2016, 2020b) properly reply to the counterarguments against MP？ Or is there any better alternative explanation that could support MP？ As regards (I), I will argue that Väyrynen’s(2018), Reiland’s(2021), and Chudnoff's (2015) alternative explanatory models for inter-subjective phenomenal contrast are not to be seen as competing explanations against the one provided by MP; rather, they are complementary to it. As regards (II), I argue that Väyrynen’s(2018), Reiland’s(2021), and Chudnoff's (2015) conterarguments against MP at most demonstrate that certain moral properties (e.g., rightness/ wrongness/goodness/badness) can’t be part of the perceptual content, but their arguments do not (or indeed cannot) rule out the possibility that moral salience can be properly construed as part of the perceptual content. In light of this, I argue that an alternative version of moral perceptualism, or what I call ‘moral salience perceptualism’, according to which “moral salience can be part of the perceptual content”, still remains alive and kicking in face of their counteraguments. Moreover, I argue that moral salience perceptualism is explanatorily superior to Werner’s (2016) version of MP in terms of explaining inter-subjective phenomenal contrast. -/- Keywords： moral perceptualism, phenomenal contrast, moral salience, moral experiences, moral judgments -/- .

Avner Baz argues that the philosophical method of cases presupposes a problematic view of language and linguistic competence, namely what he calls "the atomistic-compositional view". Combining key elements of social pragmatism and contextualism, Baz presents a view of language and linguistic competence, which he takes to be more sensitive to the open-endedness of human language. On this view, there are conditions for the "normal" and "felicitous" use of human words, conditions that Baz thinks are lacking in the context of the (...) philosophical method of cases, and which make the question that philosophers are prone to ask in that context and the answers they give to that question to be pointless. However, in this paper, I argue as follows. First, Baz's conditions for the "normal" and "felicitous" use of human words are in tension with the open-endedness of human language and the use of human words. Second, it is not even clear that those conditions are really missing in the context of the philosophical method of cases. And third, even if we grant that those conditions are missing in that context, this does not licence his damning conclusion on the philosophical method of cases since we are not forced to embrace the view of language and linguistic competence on which that damning conclusion is plausible. This last move is secured by advancing and defending a skill or virtue-based view of language and linguistic competence inspired by the later work of Donald Davidson. (shrink)

This work investigates intuitions' nature, demonstrating how philosophers can best use them in epistemology. First, the author considers several paradigmatic thought experiments in epistemology that depict the appeal to intuition. He then argues that the nature of thought experiment-generated intuitions is not best explained by an a priori Platonism. Second, the book instead develops and argues for a thin conception of epistemic intuitions. The account maintains that intuition is neither a priori nor a posteriori but multi-dimensional. It is an intentional (...) but non-propositional mental state that is also non-conceptual and non-phenomenal in nature. Moreover, this state is individuated by its progenitor, namely, the relevant thought experiment. Third, the author provides an argument for the evidential status of intuitions based on the correct account of the nature of epistemic intuition. The suggestion is the fitting-ness approach: intuition alone has no epistemic status. Rather, intuition has evidentiary value as long as it fits well with other pieces into a whole, namely, the pertinent thought experiment. Finally, the book addresses the key challenges raised by supporters of anti-centrality, according to which philosophers do not regard intuition as central evidence in philosophy. To that end, the author responds to them, showing that they fail to affect the account of intuition developed in this book. This text appeals to students and researchers working in epistemology.

Heritable personality traits often predict fundamental philosophical disagreement. This conclusion is based on studies of more than 15,000 people sampled from diverse cultures and educational backgrounds, including verifiable experts. In this chapter, we review some of this research showing links between personality and philosophical bias in free will, intentional action, and ethics. Our discussion focuses on serious challenges that these philosophical biases pose (e.g., limits on the use of philosophical intuitions as evidence). We close with discussion of the Philosophical Personality (...) Argument and brief consideration of emerging projects in applied experimental philosophy. (shrink)

The philosophical relevance of experimental psychology is hard to dispute. Much more controversial is the so‐called negative program's critique of armchair philosophical methodology, in particular the reliance on ‘intuitions’ about thought experiments. This chapter responds to that critique. It argues that, since the negative program has been forced to extend the category of intuition to ordinary judgments about real‐life cases, the critique is in immediate danger of generating into global scepticism, because all human judgments turn out to depend on intuitions. (...) Recently, some proponents of the negative program have tried to demarcate the target of their critique more narrowly. However, their attempts are still far too indiscriminate, and over‐generate scepticism. Nevertheless, once experimental philosophy has refined its own methodology, it may contribute to the refinement of the methodology of mainstream philosophy, by filtering out the effects of cognitive bias, although it offers no prospect of doing without judgments on real or imaginary cases.

Recent criticisms of medicine converge on fundamental questions about the aim of medicine. The main task of this paper is to propose an account of the aim of medicine. Discussing and rejecting the initially plausible proposal according to which medicine is pathocentric, the paper presents and defends the Autonomy Thesis, which holds that medicine is not pathocentric, but sanocentric, aiming to promote health with the final aim to enhance autonomy. The paper closes by considering the objection that the Autonomy Thesis (...) is overly permissive and allows many highly controversial procedures as legitimate parts of medicine. (shrink)

Experimental philosophy involves subjecting philosophical methods and judgments to empirical scrutiny. I begin by exploring conceptual, confirmational, and empirical factors that limit the significance of experiment-based and survey-based approaches to the evaluation of philosophical epistemic activities. I then consider specific criticisms of experimental philosophy: its experimental conditions lack ecological validity; it wrongly assumes that philosophers rely on psychologized data; it overlooks the reflective and social elements of philosophical case analysis; it misconstrues the importance of both procedural and evaluative forms of (...) philosophical expertise; it incorrectly views psychological bias as incompatible with reliability; and it generalizes to a global, self-defeating skepticism about case judgment. I explain why these criticisms should be understood as converging and interdependent. I also set out a three-level model of philosophical case judgment that frames the criticisms. (shrink)

Good physical experiments conform to the basic methodological standards of experimental design: they are objective, reliable, and valid. But is this also true of thought experiments? Especially problems of personal identity have engendered hypothetical scenarios that are very distant from the actual world. These imagined situations have been conspicuously ineffective at resolving conflicting intuitions and deciding between the different accounts of personal identity. Using prominent examples from the literature, I argue that this is due to many of these thought experiments (...) not adhering to the methodological standards that guide experimental design in nearly all other disciplines. I also show how empirically unwarranted background assumptions about human physiology render some of the hypothetical scenarios that are employed in the debate about personal identity highly misleading. (shrink)

This chapter assumes that intuitions must play a central role in explaining a priori justification and looks at the conditions under which they would be able to do so. It argues that if an appeal to intuitions is to help, they must provide epistemological resources that go beyond those provided by explanations in terms of epistemological analyticity (appeals to conceptual understanding). Accounts, like Ernest Sosa’s, which reduce intuitions to attractions to assent, and which give the understanding an indispensable role in (...) explaining the justificatory powers of such attractions, are unable to provide such a resource. As a result, such accounts must be rejected. Towards the end of the chapter, an alternative account of these issues is briefly presented, one that seems to the author to hold greater promise.

Edouard Machery argues that many traditional philosophical questions are beyond our capacity to answer. Answering them seems to require using the method of cases, a method that involves testing answers to philosophical questions against what we think about real or imagined cases. The problem, according to Machery, is that this method has proved unreliable ; what we think about these kinds of cases is both problematically heterogeneous and volatile. His bold solution: abandon the method of cases altogether and with it (...) many of the questions that we have come to associate with philosophy itself. Many of the critical responses to Machery’s book have focused on whether empirical work on judgements about philosophical cases supports his claim that the method of cases is unreliable. Our problem with these responses is that they accept that reliability is the right way to frame empirically informed concerns about the method of cases, and we think that it is not. The reason is simple: the kind of unreliability thesis that Machery needs proves to be empirically intractable, at least by anything like the current methods used by experimental philosophers, or so we shall argue here. While we have empirical grounds for thinking that unreliability arguments don’t give us reason to abandon the method of cases, we do think that there are empirical grounds for thinking that it needs to be reformed. There are other standards that we expect our methods to meet beyond mere reliability, especially standards of practical rationality, which are too often forgotten in metaphilosophical discussions that tend to focus exclusively on epistemological considerations. Methodological considerations, after all, are not just matters of epistemic normativity, but practical rationality as well. What’s more, considerations of practical rationality become particularly important when we move from the kind of extreme scepticism that Machery endorses to the kind of progressive reformation that we think should be pursued. And so we conclude by arguing that thinking about philosophical inquiry in terms of standards of practical rationality allows us both to better understand what kinds of problems recent empirical work on philosophical cognition raises for the method of cases and also how that work can point the way to reforming it.

This paper explores an emerging sub-field of both empirical bioethics and experimental philosophy, which has been called “experimental philosophical bioethics” (bioxphi). As an empirical discipline, bioxphi adopts the methods of experimental moral psychology and cognitive science; it does so to make sense of the eliciting factors and underlying cognitive processes that shape people’s moral judgments, particularly about real-world matters of bioethical concern. Yet, as a normative discipline situated within the broader field of bioethics, it also aims to contribute to substantive (...) ethical questions about what should be done in a given context. What are some of the ways in which this aim has been pursued? In this paper, we employ a case study approach to examine and critically evaluate four strategies from the recent literature by which scholars in bioxphi have leveraged empirical data in the service of normative arguments.

The experimental turn in philosophy has reached several sub-fields including ethics, epistemology, and metaphysics. This paper is among the first to apply experimental techniques to questions in the philosophy of law. Specifically, we examine Lon Fuller's procedural natural law theory. Fuller famously claimed that legal systems necessarily observe eight principles he called "the inner morality of law." We evaluate Fuller's claim by surveying both ordinary people and legal experts about their intuitions about legal systems. We conclude that, at best, we (...) should be skeptical of Fuller's inner morality of law in light of the experimental data. (shrink)

Financial incentives, learning, group consultation, and increased experimental control are among the experimental techniques economists have successfully used to deflect the behavioral challenge posed by research conducted by such scholars as Tversky and Kahneman. These techniques save the economic armchair to the extent that they align laypeople judgments with economic theory by increasing cognitive effort and reflection in experimental subjects. It is natural to hypothesize that a similar strategy might work to address the experimental or restrictionist challenge to armchair philosophy. (...) To test this hypothesis, a randomized controlled experiment was carried out, as well as two lab experiments. Three types of knowledge attribution tasks were used. No support for the hypothesis was found. The paper describes the close similarities between the economist’s response to the behavioral challenge, and the expertise defense against the experimental challenge, and presents the experiments, results, and an array of robustness checks. The upshot is that these results make the experimental challenge all the more forceful. (shrink)

According to non-cognitivism, moral sentences and judgements do not aim to represent how things morally are. This paper presents an empirical argument against this view. We begin by showing that non-cognitivism entails the prediction that after some reflection competent ordinary speakers’ semantic intuitions favor that moral sentences and judgements do not aim to represent how things morally are. At first sight, this prediction may seem to have been confirmed by previous research on folk metaethics. However, a number of methodological worries (...) lead us to doubt this interpretation. We, therefore, conducted a psychological study that alleviates these worries as far as possible. It turned out that competent ordinary speakers’ reflective semantic intuitions dominantly fail to favor that moral sentences do not aim to represent how things morally are. This challenge to non-cognitivism is defended and supplemented by considering deflationary theories of moral truth and middle ground theories in the cognitivism/non-cognitivism debate. (shrink)

We examine a prominent naturalistic line on the method of cases, exemplified by Timothy Williamson and Edouard Machery: MoC is given a fallibilist and non-exceptionalist treatment, accommodating moderate modal skepticism. But Gettier cases are in dispute: Williamson takes them to induce substantive philosophical knowledge; Machery claims that the ambitious use of MoC should be abandoned entirely. We defend an intermediate position. We offer an internal critique of Macherian pessimism about Gettier cases. Most crucially, we argue that Gettier cases needn’t exhibit (...) ‘disturbing characteristics’ that Machery posits to explain why philosophical cases induce dubious judgments. It follows, we show, that Machery’s central argument for the effective abandonment of MoC is undermined. Nevertheless, we engineer a restricted variant of the argument—in harmony with Williamsonian ideology–that survives our critique, potentially limiting philosophy’s scope for establishing especially ambitious modal theses, despite traditional MoC’s utility being partially preserved.

Objectivity, as one of the key attributes of science, has become an indispensable part of its ethos and a central theme of the philosophy of science. As such, it has been a subject of philosophical reflection by a number of authors. In our project – in which both philosophers of science and scientists participate – we examine the concept of objectivity in the natural sciences with the tools of experimental philosophy. We aim to identify specific operational dimensions of objectivity, those (...) with which current scientist actually work, thus making them accessible for further theoretical analysis and research. In this text, we present results from the first, qualitative phase of our research based on in-depth interviews and focus groups with scientists working in the Czech Republic. Further, we confront this empirical data with theoretical notions of objectivity. We also present other findings from the research and formulate hypotheses for the research’s subsequent phases.

A. J. Ayer’s Language, Truth, and Logic had been responsible for introducing the Vienna Circle’s ideas, developed within a Germanophone framework, to an Anglophone readership. Inevitably, this migration from one context to another resulted in the alteration of some of the concepts being transmitted. Such alterations have served to facilitate a number of false impressions of Logical Empiricism from which recent scholarship still tries to recover. In this paper, I will attempt to point to the ways in which LTL has (...) helped to foster the various mistaken stereotypes about Logical Empiricism which were combined into the received view. I will begin by examining Ayer’s all too brief presentation of an Anglocentric lineage for his ideas. This lineage, as we shall see, simply omits the major 19th century Germanophone influences on the rise of analytic philosophy. The Germanophone ideas he presents are selectively introduced into an Anglophone context, and directed towards various concerns that arose within that context. I will focus on the differences between Carnap’s version of the overcoming of metaphysics, and Ayer’s reconfiguration into what he calls the elimination of metaphysics. Having discussed the above, I will very briefly outline the consequences that Ayer’s radicalisation of the Vienna Circle’s doctrines had on the subsequent Anglophone reception of Logical Empiricism.

In domains like stock brokerage, clinical psychiatry, and long‐term political forecasting, experts generally fail to outperform novices. Empirical researchers agree on why this is: experts must receive direct or environmental learning feedback during training to develop reliable expertise, and these domains are deficient in this type of feedback. A growing number of philosophers resource this consensus view to argue that, given the absence of direct or environmental philosophical feedback, we should not give the philosophical intuitions or theories of expert philosophers (...) greater credence than those of novice philosophers. This article has three objectives. The first is to explore several overlooked issues concerning the strategy of generalizing from empirical studies of non‐philosophical expertise to the epistemic status of philosophical expertise. The second is to explain why empirical research into a causal relationship between direct learning feedback and enhanced expert performance does not provide good grounds for abandoning a default optimism about the epistemic superiority of expert philosophical theories. The third is to sketch a positive characterization of learning feedback that addresses developmental concerns made salient by the empirical literature on expert performance for specifically theory‐driven or “armchair” domains like philosophy. (shrink)

In some domains experts perform better than novices, and in other domains experts do not generally perform better than novices. According to empirical studies of expert performance, this is because the former but not the latter domains make available to training practitioners a direct form of learning feedback. Several philosophers resource this empirical literature to cast doubt on the quality of philosophical expertise. They claim that philosophy is like the dubious domains in that it does not make available the good, (...) direct kind of learning feedback, and thus there are empirical grounds for doubting the epistemic quality of philosophical expertise. I examine the empirical studies that are purportedly bad news for professional philosophers. On the basis of that examination, I provide three reasons why the empirical study of non-philosophical expertise does not undermine the status of philosophical expertise. First, the non-philosophical task-types from which the critics generalize are unrepresentative of relevant philosophical task-types. Second, empirical critiques of non-philosophical experts are often made relative to the performance of linear models—a comparison that is inapt in a philosophical context. Third, the critics fail to discuss findings from the empirical study of non-philosophical expertise that have more favorable implications for the epistemic status of philosophical expertise. In addition to discussing implications for philosophical expertise, this article makes progress in the philosophical analysis of the science of expertise and expert development. (shrink)

A standard principle in ethics is that moral obligation entails ability, or that “ought implies can”. A strong case has been made that this principle is not well motivated in moral psychology. This paper presents an analogous case against the theoretical motivation for the principle. The principle is in tension with several foundational areas of ethical theorizing, including research on apologies, excuses, promises, moral dilemmas, moral language, disability, and moral agency. Across each of these areas, accepting the principle that obligation (...) entails ability creates a theoretical problem that is more easily solved by rejecting it rather than accepting it. I conclude that the motivation for the principle is weak and that “ought implies can” should be rejected in ethics on theoretical grounds. (shrink)

The concept of species is one of the core concepts in biology and one of the cornerstones of evolutionary biology, yet it is rife with conceptual problems. Philosophers of biology have been discussing the concept of species for decades, and in doing so they sometimes appeal to the views of biologists. However, their statements as to what biologists think are seldom supported by empirical data. In order to investigate what biologists actually think about the key issues related to the problem (...) of species, we have conducted a survey on the sample of 193 biologists from the population of biologists from over 150 biology departments at universities in the US and the EU. This article presents and discusses the results of the survey. Some results confirm and others falsify the reiterated statements of philosophers of biology as to what biologists think, but all results we obtained should be informative and relevant for future discussions of the problem of species.

Pre-emption cases have been taken by almost everyone to imply the unviability of the simple counterfactual theory of causation. Yet there is ample motivation from scientific practice to endorse a simple version of the theory if we can. There is a way in which a simple counterfactual theory, at least if understood contrastively, can be supported even while acknowledging that intuition goes firmly against it in pre-emption cases—or rather, only in some of those cases. For I present several new pre-emption (...) cases in which causal intuition does not go against the counterfactual theory, a fact that has been verified experimentally. I suggest an account of framing effects that can square the circle. Crucially, this account offers hope of theoretical salvation—but only to the counterfactual theory of causation, not to others. Again, there is (admittedly only preliminary) experimental support for this account. (shrink)

The underrepresentation of women, people of color, and especially women of color—and the corresponding overrepresentation of white men—is more pronounced in philosophy than in many of the sciences. I suggest that part of the explanation for this lies in the role played by the idealized rational self, a concept that is relatively influential in philosophy but rarely employed in the sciences. The idealized rational self models the mind as consistent, unified, rationally transcendent, and introspectively transparent. I hypothesize that acceptance of (...) the idealized rational self leads philosophers to underestimate the influence of implicit bias on their own judgments and prevents them from enacting the reforms necessary to minimize the effects of implicit bias on institutional decision-making procedures. I consider recent experiments in social psychology that suggest that an increased sense of one’s own objectivity leads to greater reliance on bias in hiring scenarios, and I hypothesize how these results might be applied to philosophers’ evaluative judgments. I discuss ways that the idealized rational self is susceptible to broader critiques of ideal theory, and I consider some of the ways that the picture functions as a tool of active ignorance and color-evasive racism.

The problem of act individuation is a debate about the identity conditions of human acts. The fundamental question about act individuation is: how do we distinguish between actions? Three views of act individuation have dominated the literature. First, Donald Davidson and G.E.M. Anscombe have argued that a number of different descriptions refer to a single act. Second, Alvin Goldman and Jaegwon Kim have argued that each description designates a distinct act. Finally, Irving Thalberg and Judith Jarvis Thomson have averred that (...) some acts are sequences of causally related events, which include both a primitive bodily action and some of its effects. All of these accounts have assumed that a simple invariantist account of act individuation captures how ordinary people distinguish between acts. For my dissertation, I devised an experiment to test the action theorists' assumptions. My data show that people's intuitions seem to depend on the valence of the consequences of the action under consideration. So, an invariantist account is not possible. In light of the empirical results, I argue that if we seek a folk account of act individuation, then that account should be able to explain the variability that seems to be present in people's intuitions about different cases.

Much of the recent movement organized under the heading “Experimental Philosophy” has been concerned with the empirical study of responses to thought experiments drawn from the literature on philosophical analysis. I consider what bearing these studies have on the traditional projects in which thought experiments have been used in philosophy. This will help to answer the question what the relation is between Experimental Philosophy and philosophy, whether it is an “exciting new style of [philosophical] research”, “a new interdisciplinary field that (...) uses methods normally associated with psychology to investigate questions normally associated with philosophy” (Knobe et al. 2012), or whether its relation to philosophy consists, as some have suggested, in no more than the word ‘philosophy’ appearing in its title, or whether the truth lies somewhere in between these two views. I first distinguishes different strands in Experimental Philosophy, negative and positive x-phi, and x-phi pursuing philosophy as opposed to x-phi as cognitive science. Next I review some ways in which Experimental Philosophy has been criticized. Finally, I consider what would have to be true for Experimental Philosophy to have one or another sort of relevance to philosophy, whether the assumptions required are true, how we could know it, and the ideal limits of the usefulness Experimental Philosophy to philosophy. I conclude x-phi cannot in principle be a replacement for traditional first person approaches because it yields the wrong kind of knowledge and that it can nonetheless be a practical aid in conducting philosophical thought experiments. n.

The notion of an ideal reasoner has several uses in epistemology. Often, ideal reasoners are used as a parameter of (maximum) rationality for finite reasoners (e.g. humans). However, the notion of an ideal reasoner is normally construed in such a high degree of idealization (e.g. infinite/unbounded memory) that this use is unadvised. In this dissertation, I investigate the conditions under which an ideal reasoner may be used as a parameter of rationality for finite reasoners. In addition, I present and justify (...) the research program of computational epistemology, which investigates the parameter of maximum rationality for finite reasoners using computer simulations.

This chapter will consider three themes relating to the significance of intuitions in contemporary philosophy. In §1, I’ll review and explore the relationship between philosophical use of words like ‘intuitively’ and any kinds of mental states that might be called ‘intuitions’. In §2, I’ll consider the widely-discussed analogy between intuitive experience and perceptual experience, drawing out some interesting similarities and differences. Finally, in §3, I’ll introduce the recent movement of ‘experimental philosophy’, and consider to what extent its projects are tied (...) up with questions about the role of intuitions in philosophy. My primary aim will be to survey and explain; I will make no effort, however, to hide the fact that I’m a philosopher and a partisan to some of these debates. So there will be some arguments for controversial points of view, too—hopefully these will be easily perceptible, and my opponents fairly represented. Limitations of space demand a rather superficial treatment of most of our topics; endnotes will direct the reader to more comprehensive discussions. (shrink)

Many philosophers insist that the revisionary metaphysician—i.e., the metaphysician who offers a metaphysical theory which conflicts with folk intuitions—bears a special burden to explain why certain folk intuitions are mistaken. I show how evidence from cognitive science can help revisionist discharge this explanatory burden. Focusing on composition and persistence, I argue that empirical evidence indicates that the folk operate with a promiscuous teleomentalist view of composition and persistence. The folk view, I argue, deserves to be debunked. In this way, I (...) take myself to have illustrated one key role cognitive science can play in metaphysics; namely by helping the revisionary metaphysician discharge the explanatory burden of providing a plausible explanation of how the folk have gone wrong.

Gettier’s paper, “Is Justified True Belief Knowledge?,” is widely taken to be a paradigm example of the sort of philosophical methodology that has been so hotly debated in the recent literature. Reflection on it motivates the following four theses about that methodology: (A) Intuitive judgments form an epistemically distinctive kind. (B) Intuitive judgments play an epistemically privileged role in philosophical methodology. (C) If intuitive judgments play an epistemically privileged role in philosophical methodology, then their role is to be taken as (...) given inputs into generally accepted forms of reasoning. (D) Philosophical methodology is reasonable. Negative experimental philosophers have empirically challenged (D). Radical responses to their challenge include Williamson’s rejection of (A) and Cappelen and Deutsch’s rejection of (B). Here I follow traditionalists in maintaining (A), (B), and (D), but suggest questioning (C), which has largely been taken as a fixed point in the literature. (shrink)

Relationalism claims that the phenomenal character of perception is constituted by the obtaining of a non-representational psychological relation to mind-independent objects. Although relationalism provides what seems to be the most straightforward and intuitive account of how experience strikes us introspectively, it is very often believed that the argument from hallucination shows that the view is untenable. The aim of this thesis is to defend relationalism against the argument from hallucination. The argument claims that the phenomenal character of hallucination and perception (...) deserves the same account, and that relationalism cannot be true for hallucinations, therefore relationalism must be rejected. This argument relies on the Indiscriminability Principle, the claim that two experiences that are introspectively indiscriminable from each other have the same phenomenal character. Before assessing the plausibility of this principle, I first consider and dismiss versions of the argument which wouldn’t depend on IND. Although widely accepted, no satisfactory support for IND has been presented yet. In this thesis I argue that defending IND requires that we understand the notion of ‘indiscriminability’ employed in IND in an impersonal sense. I then identify what underwrites IND: the intuition that, in virtue of its superficiality, the nature of a phenomenal character must be accessible through introspection, together with the claim that it is not possible to deny IND without denying the superficiality of phenomenal characters too. I argue that the relationalist can deny IND while preserving the superficiality of phenomenal characters. This can be done by adopting a negative view of hallucination and an account of introspection whereby the phenomenal character doesn’t exist independently of one’s introspective awareness of it and where having introspective access to our experience depends on our perceptual access to the world.

There has been considerable debate in the literature as to whether work in experimental philosophy actually makes any significant contribution to philosophy. One stated view is that many X-Phi projects, notwithstanding their focus on topics relevant to philosophy, contribute little to philosophical thought. Instead, it has been claimed the contribution they make appears to be to cognitive science. In contrast to this view, here we argue that at least one approach to X-Phi makes a contribution which parallels, and also extends, (...) historically salient forms of philosophical analysis, especially contributions from Immanuel Kant, William James, Peter F. Strawson and Thomas Nagel. The framework elaborated here synthesizes philosophical theory with empirical evidence from psychology and neuroscience and applies it to three perennial philosophical problems. According to this account, the origin of these three problems can be illuminated by viewing them as arising from a tension between two distinct types of cognition, each of which is associated with anatomically independent and functionally inhibitory neural networks. If the parallel we draw, between an empirical project and historically highly influential examples of philosophical analysis, is viewed as convincing, it follows that work in the cognitive sciences can contribute directly to philosophy. Further, this conclusion holds whether the empirical details of the account are correct or not. (shrink)

An increasing number of moral realists and anti-realists have recently attempted to support their views by appeal to science. Arguments of this kind are typically criticized on the object-level. In addition, however, one occasionally also comes across a more sweeping metatheoretical skepticism. Scientific contributions to the question of the existence of objective moral truths, it is claimed, are impossible in principle; most prominently, because such arguments impermissibly derive normative from descriptive propositions, such arguments beg the question against non-naturalist moral realism, (...) science cannot inform conceptual accounts of moral judgements, and the conceptual is logically prior to the empirical. My main aim in this paper is to clarify and critically assess these four objections. Moreover, based on this assessment, I will formulate four general requirements that science-based arguments in favor of moral realism and anti-realism should meet. It will turn out that these arguments are limited in several ways, and that some existing arguments have been unsound. Yet it is still possible in principle for the empirical sciences to contribute to the moral realism/anti-realism debate. (shrink)

The “received wisdom” in contemporary analytic philosophy is that intuition talk is a fairly recent phenomenon, dating back to the 1960s. In this paper, we set out to test two interpretations of this “received wisdom.” The first is that intuition talk is just talk, without any methodological significance. The second is that intuition talk is methodologically significant; it shows that analytic philosophers appeal to intuition. We present empirical and contextual evidence, systematically mined from the JSTOR corpus and HathiTrust’s Digital Library, (...) which provide some empirical support for the second rather than the first hypothesis. Our data also suggest that appealing to intuition is a much older philosophical methodology than the “received wisdom” alleges. We then discuss the implications of our findings for the contemporary debate over philosophical methodology. (shrink)

What does it mean to know how to do something? This book develops a comprehensive account of know-how, a crucial epistemic goal for all who care about getting things right, not only with respect to the facts, but also with respect to practice. It proposes a novel interpretation of the seminal work of Gilbert Ryle, according to which know-how is a competence, a complex ability to do well in an activity in virtue of guidance by an understanding of what it (...) takes to do so. This idea is developed into a full-fledged account, Rylean responsibilism, which understands know-how in terms of the normative guidance and responsible control of one's acts. Within the complex current debate about know-how, this view occupies a middle ground position between the intellectualist claim that know-how just is propositional or objectual knowledge and the anti-intellectualist claim that know-how just is ability. In genuine know-how, practical ability and guiding intellect are both necessary, but essentially intertwined. (shrink)

Experimental philosophers are often puzzled as to why many armchair philosophers question the philosophical significance of their research. Armchair philosophers, in contrast, are often puzzled as to why experimental philosophers think their work sheds any light on traditional philosophical problems. I argue there is truth on both sides.

This paper focuses on a running dispute between Werner Callebaut’s naturalistic view and Filip Kolen and Gertrudis Van de Vijver’s transcendentalist view on the nature of philosophy of biology and the relation of this discipline to biological sciences. It is argued that, despite differences in opinion, both positions agree that philosophy of biology’s ultimate goal is to ‘move’ biology or at least be ‘meaningful’ to it. In order to make this goal clear and effective, more is needed than a polarizing (...) debate which hardly touches upon biology. Therefore, a redirection in discussion is suggested towards a reflection on the possibilities of incorporating philosophy in interdisciplinary research, and on finding concrete research questions which are of interest both to the philosopher and to the biologist.

In this paper I defend the view that positing analytic, constitutive connections among concepts best explains certain semantic-cum-conceptual intuitions. Jerry Fodor and Eric Margolis and Stephen Laurence offer alternative explanations according to which such intuitions can be explained without positing analyticities. I argue that these alternative explanations fail. As a partial diagnosis of their failure, I suggest that critics have failed to recognize the extent to which a psychologized notion of analyticity must depart from the traditional notion of ‘truth in (...) virtue of meaning alone’.

We report the results of four empirical studies designed to investigate the extent to which an epistemic closure principle for knowledge is reflected in folk epistemology. Previous work by Turri (2015a) suggested that our shared epistemic practices may only include a source-relative closure principle—one that applies to perceptual beliefs but not to inferential beliefs. We argue that the results of our studies provide reason for thinking that individuals are making a performance error when their knowledge attributions and denials conflict with (...) the closure principle. When we used research materials that overcome what we think are difficulties with Turri’s original materials, we found that participants did not reject closure. Furthermore, when we presented Turri’s original materials to non-philosophers with expertise in deductive reasoning (viz., professional mathematicians), they endorsed closure for both perceptual and inferential beliefs. Our results suggest that an unrestricted closure principle—one that applies to all beliefs, regardless of their source—provides a better model of folk patterns of knowledge attribution than a source-relative closure principle.

In this entry, we provide an overview of some of the methodological debates surrounding contextualism and consider whether they are, in effect, based on an underlying methodological dispute. We consider three modes of motivation of epistemic contextualism including i) the method of cases, ii) the appeal to linguistic analogies and iii) the appeal to conceptual analogies and functional roles. We also consider the methodological debates about contextualism arising from experimental philosophy. We conclude that i) there is no distinctive methodological doctrine (...) or set of methodological doctrines that is centrally invoked by all epistemic contextualists and ii) the substantive dispute about the truth of contextualism very frequently, although not invariably, reflects an underlying methodological dispute.

Non-descriptivists in metaethics should say more about intuitions. For one popular theory has it that case-based intuitions are in the business of correctly categorizing or classifying merely by bringing to bear a semantic or conceptual competence. If so, then the fact that all normative predicates have case-based intuitions involving them shows that they too are in the business of categorizing or classifying things. This favors a descriptivist position in metaethics—normative predicates have descriptive content—and disfavors a purely non-descriptivist position, like pure (...) expressivism. However, we can say more. We can distinguish two different sorts of intuitional state, A-grade intuitions and B-grade intuitions, based on a cluster of properties that are distinctive of each. While a hypothesis about categorization best explains the cluster of properties enjoyed by A-grade intuitions, it does not best explain the cluster of properties enjoyed by B-grade intuitions. Indeed, a non-categorizational, attitude-expressive hypothesis about the relevant meanings best explains B-grade intuitions. And intuitions involving thin normative predicates are B-grade. So intuition theory supports non-descriptivism, not descriptivism, about thin normative predicates. (shrink)

I recommend three revisions to experimental philosophy's ‘self-image’ which I suggest will enable experimentalist critics of intuition to evade several important objections to the 'negative' strand of the experimental philosophy research project. First, experimentalists should avoid broad criticisms of ‘intuition’ as a whole, instead drawing a variety of conclusions about a variety of much narrower categories of mental state. Second, experimentalists should state said conclusions in terms of epistemic norms particular to philosophical inquiry, rather than attempting to, for example, deny (...) that intuitions produce justified belief. Third, experimentalists should acknowledge the limitations of the ‘method of cases’ model of philosophical inquiry, and expand their experimental work accordingly. (shrink)

First, what are the psychological roots of our concept of free will? Second, how might progress on the first question contribute to progress regarding normative debates about the proper concept of free will? In sections two and three I address the first question. Section two discusses recent work in the experimental philosophy of free will, and motivates the study I report in section three. Section four reflects on the second question in light of the reported results. To preview, the results (...) suggest that the psychological structure of our concept of free will is sensitive to three independent features: Liberty, Ensurance, and Consciousness. I argue this supports the view that our concept is incompatibilist more than the view that our concept is compatibilist, and I discuss two proposals regarding the normative upshot. On one proposal, these results might be taken to offer some support to incompatibilism about the proper concept. A second proposal, however, makes room for a much different upshot. (shrink)

Experimental philosophy is a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy. The present review focuses on research in experimental philosophy on four central questions. First, why is it that people's moral judgments appear to influence their intuitions about seemingly nonmoral questions? Second, do people think that moral questions have objective answers, or do they see morality as fundamentally relative? Third, do people believe in free will, and do they see free (...) will as compatible with determinism? Fourth, how do people determine whether an entity is conscious? (shrink)

Experimental philosophers have gathered impressive evidence for the surprising conclusion that philosophers' intuitions are out of step with those of the folk. As a result, many argue that philosophers' intuitions are unreliable. Focusing on the Knobe Effect, a leading finding of experimental philosophy, we defend traditional philosophy against this conclusion. Our key premise relies on experiments we conducted which indicate that judgments of the folk elicited under higher quality cognitive or epistemic conditions are more likely to resemble those of the (...) philosopher. We end by showing how our experimental findings can help us better understand the Knobe Effect. (shrink)

Recent empirical work suggests that emotions are responsible for anti-consequentialist intuitions. For instance, anger places value on actions of revenge and retribution, value not derived from the consequences of these actions. As a result, it contributes to the development of retributive intuitions. I argue that if anger evolved to produce these retributive intuitions because of their biological consequences, then these intuitions are not a good indicator that punishment has value apart from its consequences. This severs the evidential connection between retributive (...) intuitions and the retributive value of punishment. This argument may generalize to other deontological intuitions and theories.

One of the important discussions in the philosophy of mathematics, is that centered on Benacerraf’s Dilemma. Benacerraf’s dilemma challenges theorists to provide an epistemology and semantics for mathematics, based on their favourite ontology. This challenge is the point on which all philosophies of mathematics are judged, and clarifying how we might acquire mathematical knowledge is one of the main occupations of philosophers of mathematics. In this thesis I argue that this discussion has overlooked an important part of mathematics, namely mathematics (...) as it is exercised by ordinary people. I do so by looking at the different theories that have been put forward in the recent debate, and showing for each of these that they are unable to account for the mathematical practices of ordinary people. In order to show that these practices do need to be accounted for, I also argue that ordinary people are doing mathematics, i.e. that they engage in properly mathematical practices. Because these practices are properly mathematical, they should be accounted for by any philosophy of mathematics. The conclusion of my thesis, then, is that current theories fail to do something that they should do, while remaining neutral on how well they perform when it comes to accounting for the practices of professional mathematicians.
