This paper has three parts. First, a discussion of our use of intuitions as evidence (reasons) in logic, mathematics, philosophy (hereafter, “the a priori disciplines”). Second, an explanation of why intuitions are evidence. The explanation is provided by modal reliabilism—the doctrine that there is a certain kind of qualified modal tie between intuitions and the truth. Third, an explanation of why there should be such a tie between intuitions and the truth. This tie is a consequence of what, by definition, (...) it is to possess the concepts involved in our intuitions. These three parts form the basis of a unified account of a priori evidence and, in turn, a priori knowledge. (shrink)

This paper provides a defense of two traditional theses: the Autonomy of Philosophy and the Authority of Philosophy. The first step is a defense of the evidential status of intuitions (intellectual seemings). Rival views (such as radical empiricism), which reject the evidential status of intuitions, are shown to be epistemically self-defeating. It is then argued that the only way to explain the evidential status of intuitions is to invoke modal reliabilism. This theory requires that intuitions have a certain qualified modal (...) tie to the truth. This result is then used as the basis of the defense of the Autonomy and Authority theses. The paper closes with a defense of the two theses against a potential threat from scientific essentialism. (shrink)

Recently in these pages it has been argued that a relatively straightforward version of an old argument based on evolutionary biology and psychology can be employed to support the view that innate ideas are a naturalistic source of metaphysical knowledge. While sympathetic to the view that the “evolutionary argument” is pregnant with philosophical implications, I show in this paper how it needs to be developed and deployed in order to avoid serious philosophical difficulties and unnecessary complications. I sketch a revised (...) version of the evolutionary argument, place it in a new context, and show that this version in this context is not vulnerable to the standard criticisms levelled against arguments of this general type. The philosophical import of this version of the argument lies not in any metaphysical conclusions it sanctions directly, but in the support it lends to the metaphilosophy of commonsense. (shrink)

The claim that contemporary analytic philosophers rely extensively on intuitions as evidence is almost universally accepted in current meta-philosophical debates and it figures prominently in our self-understanding as analytic philosophers. No matter what area you happen to work in and what views you happen to hold in those areas, you are likely to think that philosophizing requires constructing cases and making intuitive judgments about those cases. This assumption also underlines the entire experimental philosophy movement: only if philosophers rely on intuitions (...) as evidence are data about non-philosophers' intuitions of any interest to us. Our alleged reliance on the intuitive makes many philosophers who don't work on meta-philosophy concerned about their own discipline: they are unsure what intuitions are and whether they can carry the evidential weight we allegedly assign to them. The goal of this book is to argue that this concern is unwarranted since the claim is false: it is not true that philosophers rely extensively (or even a little bit) on intuitions as evidence. At worst, analytic philosophers are guilty of engaging in somewhat irresponsible use of 'intuition'-vocabulary. While this irresponsibility has had little effect on first order philosophy, it has fundamentally misled meta-philosophers: it has encouraged meta-philosophical pseudo-problems and misleading pictures of what philosophy is.

Michael Devitt ([2006a], [2006b]) argues that, insofar as linguists possess better theories about language than non-linguists, their linguistic intuitions are more reliable. Culbertson and Gross ([2009]) presented empirical evidence contrary to this claim. Devitt ([2010]) replies that, in part because we overemphasize the distinction between acceptability and grammaticality, we inter alia misunderstand linguists’ claims, fall into inconsistency, and fail to see how our empirical results can be squared with his position. We reply in this note. Inter alia we argue that (...) Devitt’s focus on grammaticality intuitions, rather than acceptability intuitions, distances his discussion from actual linguistic practice. We close by questioning a demand that drives his discussion—viz., that, for linguistic intuitions to supply evidence for linguistic theorizing, a better account of why they are evidence is required.

Practitioners of the new ‘experimental philosophy’ have collected data that appear to show that some philosophical intuitions are culturally variable. Many experimental philosophers take this to pose a problem for a more traditional, ‘armchair’ style of philosophizing. It is argued that this is a mistake that derives from a false assumption about the character of philosophical methods; neither philosophy nor its methods have anything to fear from cultural variability in philosophical intuitions.

Frank Jackson has argued that only if we have a priori knowledge of the extension-fixers for many of our terms can we vindicate the methodological practice of relying on intuitions to decide between philosophical theories. While there has been much discussion of Jackson's claim that we have such knowledge, there has been comparatively little discussion of this most powerful argument for that claim. Here I defend an alternative explanation of our intuitions about possible cases, one that does not rely on (...) a priori extension-fixers. This alternative explanation provides a vindication of our reliance on intuitions, while blocking Jackson's abductive argument for a priori semantic knowledge. In brief, I argue that we should regard our armchair intuitions as providing an important, a priori source of evidence for hypotheses about the contents of our implicit referential policies with regard to our terms. But all such hypotheses have a potential falsifier that is only discoverable empirically. In other words, gold-standard evidence for such hypotheses is always empirical. (shrink)

Many philosophers claim that intuitions are evidential. Yet it is hard to see how introspecting one's mental states could provide evidence for such synthetic truths as those concerning, for example, the abstract and the counterfactual. Such considerations have sometimes been taken to lead to mentalism---the view that philosophy must concern itself only with matters of concept application or other mind-dependent topics suited to a contemplative approach---but this provides us with a poor account of what it is that philosophers take themselves (...) to be doing, for many of them are concerned with the extra-mental facts about the universe. Evidentialism therefore gestates a disaster for philosophy, for it ultimately demands an epistemology for the investigation into such matter as the abstract and the modal that simply will not be forthcoming. We make a different suggestion: That intuitions are inclinations to believe. Hence, according to us, a philosophical argument does well, as a socio-rhetorical matter of fact, when it is founded on premises philosophers are generally inclined to believe, whether or not those inclinations to believe connect appropriately to the extra-mental facts. Accordingly, the role of intuitions (inclinations to believe) in philosophical methodology is non-evidential, and the question of how they could be used as evidence falls away. (shrink)

Today, experimental philosophers challenge traditional appeals to intu- ition; they empirically collect folk intuitions and then use their findings to attack philosophers’ intuitions. However this movement is not uniform. Radical experi- mentalists criticize the use of intuitions in philosophy altogether and they have been mostly attacked. Contrariwise, moderate experimentalists imply that laypersons’ in- tuitions are somehow relevant to philosophical problems. Sometimes they even use folk intuitions in order to advance theoretical theses. In this paper I will try to challenge the (...) so-called moderate experimental attempts to rely on intuition in order to promote philosophical theses. (shrink)

In a recent paper Weinberg (2007) claims that there is an essential mark of trustworthiness which typical sources of evidence as perception or memory have, but philosophical intuitions lack, namely that we are able to detect and correct errors produced by these “hopeful” sources. In my paper I will argue that being a hopeful source isn't necessary for providing us with evidence. I then will show that, given some plausible background assumptions, intuitions at least come close to being hopeful, if (...) they are reliable. If this is true, Weinberg's new challenge comes down to the claim that philosophical intuitions are not reliable since they are significantly unstable. In the second part of my paper I will argue that and why the experimentally established instability of folk intuitions about philosophical cases does not show that philosopher's expert intuitions about these cases are instable. (shrink)

Semantic externalism about a class of expressions is often thought to make conceptual analysis about members of that class impossible. In particular, since externalism about natural kind terms makes the essences of natural kinds empirically discoverable, it seems that mere reflection on one's natural kind concept will not be able to tell one anything substantial about what it is for something to fall under one's natural kind concepts. Many hold the further view that one cannot even know anything substantial about (...) the reference-fixers of one's natural kind concepts by armchair reflection. In this paper I want to question this latter view and claim that, because of the way our standard methodology of doing theories of reference relies on semantic intuitions, typical externalists in fact presuppose that one can know the reference-fixers of one's natural kind concepts by mere armchair reflection. The more interesting question is how substantial such knowledge can be. I also take some steps toward answering this question. (shrink)

Recently, a new movement of philosophers, called 'experimental philosophy', has suggested that the philosophers' favored armchair is in flames. In order to assess some of their claims, it is helpful to provide a theoretical background against which we can discuss whether certain facts are, or could be, evidence for or against a certain view about how philosophical intuitions work and how good they are. In this paper, I will be mostly concerned with providing such a theoretical background, and I will (...) start discussing in which way experimental philosophy challenges the reliability of philosophical intuitions and how its challenge fits into some more theoretical considerations that also point towards a reliability problem for intuitions. The paper attempts to argue that a certain account of intuitions—the imaginationist account—is available which is well-suited for explicating the expertise reply to the challenge of experimental philosophy.

In this brief introduction, we would first like to explain how these two special issues of Philosophical Psychology ( 23.3 and 23.4 ) actually came about. In addition, we will provide an outline of their overall structure and shortly summarize the featured papers.

What is it to explain away an intuition? Philosophers regularly attempt to explain intuitions away, but it is often unclear what the success conditions for their project consist in. I attempt to articulate some of these conditions, taking philosophical case studies as guides, and arguing that many attempts to explain away intuitions underestimate the challenge the project of explaining away involves. I will conclude, therefore, that explaining away intuitions is a more difficult task than has sometimes been appreciated; I also (...) suggest, however, that the importance of explaining away intuitions has often been exaggerated. (shrink)

In the essay, I compare the aims and especially the methods of philosophers and grammarians. It transpires that there are several interesting similarities to be found with the method and aim in particular of traditional 'armchair philosophers'. I argue that these similarities go far enough to suggest that if armchair philosophers' method is in a state of challenge, as is claimed by a number of experimental philosophers, then the same can be said about the method of grammarians. However, I also (...) try to show that it is not easy for experimental philosophers to frame their critique in a way that avoids construing its target too broadly, which would lead to unacceptable consequences. I conclude with some brief remarks on the extent to which a properly targeted critique can provide a challenge for traditional philosophical method. (shrink)

Radical experimentalists argue that we should give up using intuitions as evidence in philosophy. In this paper, I first argue that the studies presented by the radical experimentalists in fact suggest that some intuitions are reliable. I next consider and reject a different way of handling the radical experimentalists' challenge, what I call the Argument from Robust Intuitions. I then propose a way of understanding why some intuitions can be unreliable and how intuitions can conflict, and I argue that on (...) this understanding, both moderate experimentalism and the standard philosophical practice of using intuitions as evidence can help resolve these conflicts. (shrink)

A growing body of empirical literature challenges philosophers’ reliance on intuitions as evidence based on the fact that intuitions vary according to factors such as cultural and educational background, and socio-economic status. Our research extends this challenge, investigating Lehrer's appeal to the Truetemp Case as evidence against reliabilism. We found that intuitions in response to this case varyaccording to whether, and which, other thought-experiments are considered first. Our results show that compared to subjects who receive the Truetemp Case first, subjects (...) first presented with a clear case of knowledge are less willing to attribute knowledge in the Truetemp Case, and subjects first presented with a clear case of non-knowledge are more willing to attribute knowledge in the Truetemp Case. Wecontend that this instability undermines the supposed evidential status of these intuitions, such that philosophers who deal in intuitions can no longer rest comfortably in their armchairs. (shrink)

Standard philosophical methodology which proceeds by appeal to intuitions accessible "from the armchair" has come under criticism on the basis of empirical work indicating unanticipated variability of such intuitions. Loose constitutivity---the idea that intuitions are partly, but not strictly, constitutive of the concepts that appear in them---offers an interesting line of response to this empirical challenge. On a loose constitutivist view, it is unlikely that our intuitions are incorrect across the board, since they partly fix the facts in question. But (...) we argue that this ratification of intuitions is at best rough and generic, and can only do the required methodological work if it operates in conjunction with some sort of further criteria of theory selection. We consider two that we find in the literature: naturalness (Brian Weatherson, borrowing from Lewis) and charity (Henry Jackman, borrowing from Davidson). At the end of the day, neither provides the armchair philosopher complete shelter from extra-armchair inquiry. (shrink)

Recent experimental philosophy arguments have raised trouble for philosophers' reliance on armchair intuitions. One popular line of response has been the expertise defense: philosophers are highly-trained experts, whereas the subjects in the experimental philosophy studies have generally been ordinary undergraduates, and so there's no reason to think philosophers will make the same mistakes. But this deploys a substantive empirical claim, that philosophers' training indeed inculcates sufficient protection from such mistakes. We canvass the psychological literature on expertise, which indicates that people (...) are not generally very good at reckoning who will develop expertise under what circumstances. We consider three promising hypotheses concerning what philosophical expertise might consist in: (i) better conceptual schemata; (ii) mastery of entrenched theories; and (iii) general practical know-how with the entertaining of hypotheticals. On inspection, none seem to provide us with good reason to endorse this key empirical premise of the expertise defense. (shrink)

In this paper we propose to argue for two claims. The first is that a sizeable group of epistemological projects – a group which includes much of what has been done in epistemology in the analytic tradition – would be seriously undermined if one or more of a cluster of empirical hypotheses about epistemic intuitions turns out to be true. The basis for this claim will be set out in Section 2. The second claim is that, while the jury is (...) still out, there is now a substantial body of evidence suggesting that some of those empirical hypotheses are true. Much of this evidence derives from an ongoing series of experimental studies of epistemic intuitions that we have been conducting. A preliminary report on these studies will be presented in Section 3. In light of these studies, we think it is incumbent on those who pursue the epistemological projects in question to either explain why the truth of the hypotheses does not undermine their projects, or to say why, in light of the evidence we will present, they nonetheless assume that the hypotheses are false. In Section 4, which is devoted to Objections and Replies, we’ll consider some of the ways in which defenders of the projects we are criticizing might reply to our challenge. Our goal, in all of this, is not to offer a conclusive argument demonstrating that the epistemological projects we will be criticizing are untenable. Rather, our aim is to shift the burden of argument. (shrink)

The present paper revisits the main methodological problems with conceptual analysis and considers two attempts to rectify them in terms of prototypes and reflective equilibria, respectively. Finding both wanting for the purposes of epistemological analysis, a naturalistic alternative is then sketched that explores the positive implications of aforementioned problems for the demarcation of the respective roles of intuitions and empirical investigation within three epistemological domains, viz., the evaluation of epistemological hypotheses, the amelioration of epistemic practices, and the construction of a (...) theory of epistemic value. (shrink)

The present study is concerned the viability of the primary method in contemporary philosophy, i.e., conceptual analysis. Starting out by tracing the roots of this methodology to Platonic philosophy, the study questions whether such a methodology makes sense when divorced from Platonic philosophy, and develops a framework for a kind of analysis that is more in keeping with recent psychological research on categorization. Finally, it is shown that this kind of analysis can be applied to the concept of justification in (...) a manner that furthers the epistemological goal of providing intellectual guidance. (shrink)

This paper defends a moderate intuitionism by extending a version of that view previously put forward and responding to some significant objections to it that have been posed in recent years. The notion of intuition is clarified, and various kinds of intuition are distinguished and interconnected. These include doxastic intuitions and intuitive seemings. The concept of inference is also clarified. In that light, the possibility of non-inferential intuitive justification is explained in relation to both singular moral judgments, which intuitionists do (...) not take to be self-evident, and basic moral principles, which they typically do take to be self-evident in a sense explicated in the paper. This explanation is accomplished in part by drawing some analogies between moral and perceptual judgments in the light of a developmental conception of knowledge. The final section of the paper presents a partial account of rational disagreement and indicates how the kind of intuitionist view defended can allow for rational disagreement between apparent epistemic peers. (shrink)

In 1955, Goodman set out to 'dissolve' the problem of induction, that is, to argue that the old problem of induction is a mere pseudoproblem not worthy of serious philosophical attention. I will argue that, under naturalistic views of the reflective equilibrium method, it cannot provide a basis for a dissolution of the problem of induction. This is because naturalized reflective equilibrium is -- in a way to be explained -- itself an inductive method, and thus renders Goodman's dissolution viciously (...) circular. This paper, then, examines how the old problem of induction crept back in while nobody was looking. (shrink)

The basic aim of Alvin Goldman’s approach to epistemology, and the tradition it represents, is naturalistic; that is, epistemological theories in this tradition aim to identify the naturalistic, nonnormative criteria on which justified belief supervenes (Goldman, 1986; Markie, 1997). The basic method of Goldman’s epistemology, and the tradition it represents, is the reflective equilibrium test; that is, epistemological theories in this tradition are tested against our intuitions about cases of justified and unjustified belief (Goldman, 1986; Markie, 1997). I will argue (...) that the prospect of having to reject their standard methodology is one epistemologists have to take very seriously; and I will do this by arguing that some current rival theories of epistemic justification are in fact in reflective equilibrium with our intuitions about cases of justified and unjustified belief. That is, I will argue that intuition underdetermines theory choice in epistemology, in much the way that observation underdetermines theory choices in empirical sciences. If reflective equilibrium leads to the underdetermination problem I say it leads to, then it cannot satisfy the aims of contemporary epistemology, and so cannot serve as its standard methodology.

This paper contains replies to comments on the author's paper "A Priori Knowledge and the Scope of Philosophy." Several points in the argument of that paper are given further clarification: the notion of our standard justificatory procedure, the notion of a basic source of evidence, and the doctrine of modal reliabilism. The reliability of intuition is then defended against Lycan's skepticism and a response is given to Lycan's claim that the scope of a priori knowledge does not include philosophically central (...) topics such as the nature of consciousness. Next a counterfactual account of intuitions proposed by Sosa is criticized. Finally, in response to certain questions raised by Sosa, the explanation of the evidential status of intuition offered in the original paper receives further elaboration. (shrink)

Modal intuitions are the primary source of modal knowledge but also of modal error. According to the theory of modal error in this paper, modal intuitions retain their evidential force in spite of their fallibility, and erroneous modal intuitions are in principle identifiable and eliminable by subjecting our intuitions to a priori dialectic. After an inventory of standard sources of modal error, two further sources are examined in detail. The first source - namely, the failure to distinguish between metaphysical possibility (...) and various kinds of epistemic possibility - turns out to be comparatively easy to untangle and poses little threat to intuition-driven philosophical investigation. The second source is the local (i.e., temporary) misunderstanding of one's concepts (as opposed to outright Burgean misunderstanding). This pathology may be understood on analogy with a patient who is given a clean bill of health at his annual check-up, despite his having a cold at the time of the check-up: although the patient's health is locally (temporarily) disrupted, his overall health is sufficiently good to enable him to overcome the cold without external intervention. Even when our understanding of certain pivotal concepts has lapsed locally, our larger body of intuitions is sufficiently reliable to allow us, without intervention, to ferret out the modal errors resulting from this lapse of understanding by means of dialectic and/or a process of a priori reflection. This source of modal error, and our capacity to overcome it, has wide-ranging implications for philosophical method - including, in particular, its promise for disarming skepticism about the classical method of intuition-driven investigation itself. Indeed, it is shown that skeptical accounts of modal error (e.g., the accounts given by Hill, Levin, and several others) are ultimately self-defeating. (shrink)

The paper begins with a clarification of the notions of intuition (and, in particular, modal intuition), modal error, conceivability, metaphysical possibility, and epistemic possibility. It is argued that two-dimensionalism is the wrong framework for modal epistemology and that a certain nonreductionist approach to the theory of concepts and propositions is required instead. Finally, there is an examination of moderate rationalism.

The topic of a priori knowledge is approached through the theory of evidence. A shortcoming in traditional formulations of moderate rationalism and moderate empiricism is that they fail to explain why rational intuition and phenomenal experience count as basic sources of evidence. This explanatory gap is filled by modal reliabilism -- the theory that there is a qualified modal tie between basic sources of evidence and the truth. This tie to the truth is then explained by the theory of concept (...) possession: this tie is a consequence of what, by definition, it is to possess (i.e., to understand) one’s concepts. A corollary of the overall account is that the a priori disciplines (logic, mathematics, philosophy) can be largely autonomous from the empirical sciences. (shrink)

The paper elaborates upon various points and arguments in the author's "A Priori Knowledge and the Scope of Philosophy".

Radical empiricism is the view that a person's experiences (sensory and introspective), or a person's observations, constitute the person's evidence. This view leads to epistemic self-defeat. There are three arguments, concerning respectively: (1) epistemic starting points; (2) epistemic norms; (3) terms of epistemic appraisal. The source of self-defeat is traced to the fact that empiricism does not count a priori intuition as evidence (where a priori intuition is not a form of belief but rather a form of seeming, specifically intellectual (...) as opposed to sensory). Moderate rationalism, by contrast, avoids self-defeat. (shrink)

Scientific essentialism is the view that some necessities (e.g., water = H2O) can be known only with the aid of empirical science. The thesis of the paper is that scientific essentialism does not extend to the central questions of philosophy and that these questions can be answered a priori. The argument is that the evidence required for the defense of scientific essentialism (e.g., twin earth intuitions) is reliable only if the intuitions required by philosophy to answer its central questions is (...) also reliable. Included is an outline of a modal reliabilist theory of basic evidence and a concept-possession account of the reliability of a priori intuition. (shrink)

Abstract I agree with Sosa that intuitions are best thought of as attractions to believe a certain proposition merely on the basis of understanding it. However, I don’t think it is constitutive of them that they supply strictly foundational justification for the propositions they justify, though I do believe that it is important that the intuition of a suitable subject be thought of as a prima facie justification for his intuitive judgment, independently of the reliability of his underlying capacities. I (...) also think that we need to be able to explain how mere understanding of a proposition can confer upon us an ability to have reliable intuitions, that we cannot simply take that idea for granted. And that when try to explain that, our best avenue for doing so is to take the intuitions as constituting the understanding of which they are said to be a manifestation. (shrink)

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

I will ask the conditional question: if folk attributions of "know" are not sensitive to the stakes and/or the salience of error, does this cast doubt on contextualism or subject-sensitive invariantism (SSI)? I argue that if it should turn out that folk attributions of knowledge are insensitive to such factors, then this undermines contextualism, but not SSI. That is not to say that SSI is invulnerable to empirical work of any kind. Rather, I defend the more modest claim that leading (...) versions of SSI are not undermined by one particular kind of experimental result, namely the recent suggestion that knowledge attributions are insensitive to the stakes.

What is the nature of the evidence provided by thought experiments in philosophy? For instance, what evidence is provided by the Gettier thought experiment against the JTB theory of knowledge? According to one view, it provides as evidence only a certain psychological proposition, e.g. that it seems to one that the subject in the Gettier case lacks knowledge. On an alternative, nonpsychological view, the Gettier thought experiment provides as evidence the nonpsychological proposition that the subject in the Gettier case lacks (...) knowledge (e.g., Williamson 2007). Given the centrality of thought experiments to philosophical enquiry, the correct account of thought experiment evidence is important for understanding the nature of philosophical methodology. Further, Williamson argues that a misguided adherence to the psychological view of thought experiment evidence encourages scepticism about philosophy since it opens a gap between our evidence and the nonpsychological subject matter of philosophy. The main aim of this paper is to defend the psychological view against recent objections. In particular, I argue that even if thought experiment evidence is psychological, it can still provide justification for non-psychological claims which are the subject matter of philosophy. (shrink)

Experimental philosophers have recently questioned the use of intuitions as evidence in philosophical methods. J. R. Kuntz and J. R.C. Kuntz (2011) conduct an experiment suggesting that these critiques fail to be properly motivated because they fail to capture philosophers' preferred conceptions of intuition‐use. In this response, it is argued that while there are a series of worries about the design of this study, the data generated by Kuntz and Kuntz support, rather than undermine, the motivation for the experimentalist critiques (...) of intuition they aim to criticize. (shrink)

According to the most popular non-skeptical views about intuition, intuitions justify beliefs because they are based on understanding. More precisely: if intuiting that p justifies you in believing that p it does so because your intuition is based on your understanding of the proposition that p. The aim of this paper is to raise some challenges for accounts of intuitive justification along these lines. I pursue this project from a non-skeptical perspective. I argue that there are cases in which intuiting (...) that p justifies you in believing that p, but such that there is no compelling reason to think this is because your intuition is based on your understanding of the proposition that p. (shrink)

In this paper I assume that we have some intuitive knowledge—i.e. beliefs that amount to knowledge because they are based on intuitions. The question I take up is this: given that some intuition makes a belief based on it amount to knowledge, in virtue of what does it do so? We can ask a similar question about perception. That is: given that some perception makes a belief based on it amount to knowledge, in virtue of what does it do so? (...) A natural idea about perception is that a perception makes a belief amount to knowledge in part by making you sensorily aware of the concrete objects it is about. The analogous idea about intuition is that an intuition makes a belief amount to knowledge in part by making you intellectually aware of the abstract objects it is about. I expand both ideas into fuller accounts of perceptual and intuitive knowledge, explain the main challenge to this sort of account of intuitive knowledge (i.e. the challenge of making sense of intellectual awareness), and develop a response to it. (shrink)

In this paper I articulate and defend a view that I call phenomenal dogmatism about intuitive justification. It is dogmatic because it includes the thesis: if it intuitively seems to you that p, then you thereby have some prima facie justification for believing that p. It is phenomenalist because it includes the thesis: intuitions justify us in believing their contents in virtue of their phenomenology—and in particular their presentational phenomenology. I explore the nature of presentational phenomenology as it occurs perception, (...) and I make a case for thinking that it is present in a wide variety of logical, mathematical, and philosophical intuitions.

Despite well-established results in survey methodology, many experimental philosophers have not asked whether and in what way conclusions about folk intuitions follow from people’s responses to their surveys. Rather, they appear to have proceeded on the assumption that intuitions can be simply read off from survey responses. Survey research, however, is fraught with difficulties. I review some of the relevant literature—particularly focusing on the conversational pragmatic aspects of survey research—and consider its application to common experimental philosophy surveys. I argue for (...) two claims. First, that experimental philosophers’ survey methodology leaves the facts about folk intuitions massively underdetermined; and second, that what has been regarded as evidence for the instability of philosophical intuitions is, at least in some cases, better accounted for in terms of subjects’ reactions to subtle pragmatic cues contained in the surveys.

As a procedure, reflective equilibrium (RE) is simply a familiar kind of standard scientific method with a new name. (For descriptions of reflective equilibrium, see Daniels 1979, 1980b, 1984; Goodman 1965; Rawls 1971.) A theory is constructed to account for a set of observations. Recalcitrant data may be rejected as noise or explained away as the effects of interference of some sort. Recalcitrant data that cannot be plausibly dismissed force emendations in theory. What counts as a plausible dismissal depends, among (...) other things, on the going theory, as well as on background theory and on knowledge that may be relevant to under-standing the experimental design that is generating the observations, including knowledge of the apparatus and observation conditions. This sort of mutual adjustment between theory and data is a familiar feature of scientific practice. Whatever authority RE seems to have comes, I think, from a tacit or explicit recognition that it has the same form as this familiar sort of scientific inference. One way to see the rationale underlying this procedure in science is to focus on prediction. Think of prediction as a matter of projecting what is known onto uncharted territory. To do this, you need a vehicle—a theory—that captures some invariant or pattern in what is known so that you can project it onto the unknown. How convincing the projection is depends on two factors: (i) how sure one is of the observational base, and (ii) how sure one is that the theory gets the invariants right. The two factors are not independent, of course. One's confidence in the observational base will be affected by how persuasively the theory identifies and dismisses noise; one's confidence in the theory, on the other hand, will depend on one's confidence in the observations it takes seriously. Prediction is important as a <span class='Hi'>test</span> of theory precisely because verified predictions seem to show that the theory has correctly captured the general in the particular, that it has got the drift of the observational evidence in which our confidence is ultimately grounded..

Moral decision procedures such as principlism or casuistry require intuition at certain junctures, as when a principle seems indeterminate, or principles conflict, or we wonder which paradigm case is most relevantly similar to the instant case. However, intuitions are widely thought to lack epistemic justification, and many ethicists urge that such decision procedures dispense with intuition in favor of forms of reasoning that provide discursive justification. I argue that discursive justification does not eliminate or minimize the need for intuition, or (...) constrain our intuitions. However, this is not a problem, for intuitions can be justified in easy or obvious cases, and decision procedures should be understood as heuristic devices for reaching judgments about harder cases that approximate the justified intuitions we would have about cases under ideal conditions, where hard cases become easy. Similarly, the forms of reasoning which provide discursive justification help decision procedures perform this heuristic function not by avoiding intuition, but by making such heuristics more accurate. Nonetheless, it is possible to demand too much justification; many clinical ethicists lack the time and philosophical training to reach the more elaborate levels of discursive justification. We should keep moral decision procedures simple and user-friendly so that they will provide what justification can be achieved under clinical conditions, rather than trying to maximize our epistemic justification out of an overstated concern about intuition.

What are the consequences of evolutionary theory for the epistemic standing of our beliefs? Evolutionary considerations can be used to either justify or debunk a variety of beliefs. This paper argues that evolutionary approaches to human cognition must at least allow for approximately reliable cognitive capacities. Approaches that portray human cognition as so deeply biased and deficient that no knowledge is possible are internally incoherent and self-defeating. As evolutionary theory offers the current best hope for a naturalistic epistemology, evolutionary approaches (...) to epistemic justification seem to be committed to the view that our sensory systems and belief-formation processes are at least approximately accurate. However, for that reason they are vulnerable to the charge of circularity, and their success seems to be limited to commonsense beliefs. This paper offers an extension of evolutionary arguments by considering the use of external media in human cognitive processes: we suggest that the way humans supplement their evolved cognitive capacities with external tools may provide an effective way to increase the reliability of their beliefs and to counter evolved cognitive biases.

Linguists take the intuitive judgments of speakers to be good evidence for a grammar. Why? The Chomskian answer is that they are derived by a rational process from a representation of linguistic rules in the language faculty. The paper takes a different view. It argues for a naturalistic and non-Cartesian view of intuitions in general. They are empirical central-processor responses to phenomena differing from other such responses only in being immediate and fairly unreflective. Applying this to linguistic intuitions yields an (...) explanation of their evidential role without any appeal to the representation of rules.

Much contemporary experimental philosophy involves taking surveys of ?folk? subjects to test their intuitions involving philosophically relevant concepts. The results of these surveys are often claimed to be surprising, and treated as evidence that the relevant folk intuitions cannot be predicted from the ?armchair?. We conducted an experiment to test these claims, and found that a solid majority of philosophers could predict even results that were claimed to be surprising in the literature. We discuss some methodological implications as well as (...) some possible explanations for the common surprisingness claims. (shrink)

Advocates of the use of intuitions in philosophy argue that they are treated as evidence because they are evidential. Their opponents agree that they are treated as evidence, but argue that they should not be so used, since they are the wrong kinds of things. In contrast to both, we argue that, despite appearances, intuitions are not treated as evidence in philosophy whether or not they should be. Our positive account is that intuitions are a subclass of inclinations to believe. (...) Our thesis explains why intuitions play a role in persuasion and inquiry, without conceding that they are evidential. The account also makes predictions about the structure of intuitions that are confirmed by independent arguments. (shrink)

What exactly is a philosophical intuition? And what makes such an intuition reliable, when it is reliable? This paper provides a terminological framework that is able answer to the first question, and then puts the framework to work developing an answer to the second question. More specifically, the paper argues that we can distinguish between two different "evidential roles" which intuitions can occupy: under certain conditions they can provide information about the representational structure of an intuitor's concept, and under different (...) conditions, they can provide information about whether or not a property is instantiated. The paper describes two principles intended to capture the difference between the two sets of conditions---that is, the paper offers a principle that explains when an intuition will be a reliable source of evidence about the representation structure of an intuitor's concept, and another principle that explains when an intuition will be a reliable source of evidence about whether or not a property is instantiated. The paper concludes by briefly arguing that, insofar as philosophers are interested using intuitions to determine whether or not some philosophically interesting property is instantiated by some scenario (for instance, whether knowledge is instantiated in a Gettier-case), the reliability of the intuition in question does not depend on whether or not the intuition is widely shared.

Thought experiments play an important cognitive role in many fields of inquiry, especially in physics and philosophy. Do they also matter in revealed theology? In addressing this question, I will argue first why it is important to do so, then elaborate on the characteristic features of such thought experiments in revealed theology, and finally discuss two instances of thought experimenting in Augustine.

George Bealer argues that intuitions are not only reliable indicators of truth, they are necessary to the philosophical endeavor. Specifically, he thinks that intuitions are essential sources of evidence for epistemic justification. I argue that Bealer's defense of intuitions either (1) is insufficient to show that actual human beings are in a position to use intuitions for epistemic justification, or (2) begs the question. The growing empirical data about our intuitions support the view that humans are not creatures appropriately positioned (...) to use intuitions for epistemic justification in the way Bealer suggests. Without the appropriate empirical evidence that humans are beings so positioned, his view begs the question against those who think that intuitions are not reliable guides to truth. (shrink)

Psychological explanations of philosophical intuitions can help us assess their evidentiary value, and our warrant for accepting them. To explain and assess conceptualor classificatory intuitions about specific situations, some philosophers have suggested explanations which invoke heuristic rules proposed by cognitive psychologists. The present paper extends this approach of intuition assessment by heuristics-based explanation, in two ways: It motivates the proposal of a new heuristic, and shows that this metaphor heuristic helps explain important but neglected intuitions: general factualintuitions which have been (...) highly influential in the philosophies of mind and perceptionbut neglected in on-going debates in the epistemology of philosophy. To do so, the paper integrates results from three philosophically pertinent but hitherto largely unconnected strands of psychological research: research on intuitive judgement, analogy and metaphor, and memory-based processing, respectively. The paper shows that theheuristics-based explanation thus obtained satisfies the key requirements cognitive psychologists impose on such explanations, that it can explain the philosophicalintuitions targeted, and that this explanation supports normative assessment of theintuitions' evidentiary value: It reveals whether particular intuitions are due to proper exercise of cognitive competencies or constitute cognitive illusions.

The capacity to represent things to ourselves as possible plays a crucial role both in everyday thinking and in philosophical reasoning; this volume offers much-needed philosophical illumination of conceivability, possibility, and the relations between them.

This paper defends strict invariantism against some philosophical and empirical data that have been taken to compromise it. The defence involves a combination of a priori philosophical arguments and empirically informed theorizing. The positive account of the data is an epistemic focal bias account that draws on cognitive psychology. It involves the assumption that, owing to limitations of the involved cognitive resources, intuitive judgments about knowledge ascriptions are generated by processing only a limited part of the available information?the part that (...) is in focus. According to the epistemic focal bias account, the intuitive judgments about knowledge ascriptions that constitute contrast effects amount to false positives, whereas the intuitive judgments that constitute salient alternatives effects amount to false negatives. I conclude by considering how the basic epistemic focal bias account may be developed further by reference to relevant alternatives theory in epistemology, pragmatics in the philosophy of language, and dual process theory in cognitive psychology.

Intuitions play a critical role in analytical philosophical activity. But do they qualify as genuine evidence for the sorts of conclusions philosophers seek? Skeptical arguments against intuitions are reviewed, and a variety of ways of trying to legitimate them are considered. A defense is offered of their evidential status by showing how their evidential status can be embedded in a naturalistic framework.

In the first part of this paper I will characterize the specific nature of rational intuition. It will be claimed that rational intuition is an evidential state with modal content that has an a priori source. This claim will be defended against several objections. The second part of the paper deals with the so-called explanationist objection against rational intuition as a justifying source. According to the best reading of this objection, intuition cannot justify any judgment since there is no metaphysical (...) explanation of its reliability. It will be argued that in the case of intuition the very demand of such an explanation is based on a category mistake. (shrink)

The present paper offers an analogical support for the use of rational intuition, namely, if we regard sense perception as a mental faculty that (in general) delivers justified beliefs, then we should treat intuition in the same manner. I will argue that both the cognitive marks of intuition and the role it traditionally plays in epistemology are strongly analogous to that of perception, and barring specific arguments to the contrary, we should treat rational intuition as a source of prima facie (...) justified beliefs. There are two main arguments against the intuition-perception analogy that I will consider and find lacking. First is that while we do use perceptions as evidence to believe certain propositions, in fact no one ever does use intuition evidentially. The second argument, stemming from experimental philosophy, grants that philosophers do use intuitions evidentially, but this practice is fatally unlike that of perception, in that perception yields warranted beliefs and intuition does not.

This paper defends the view that philosophical propositions are merely relatively true, i.e. true relative to a doxastic perspective defined at least in part by a non-inferential belief-acquiring method. Here is the strategy: first, the primary way that contemporary philosophers defend their views is through the use of rational intuition, and this method delivers non-inferential, basic beliefs which are then systematized and brought into reflective equilibrium. Second, Christian theologians use exactly the same methodology, only replacing intuition with revelation. Third, intuition (...) and revelation yield frequently inconsistent output beliefs. Fourth, there is no defensible reason to prefer the dictates of intuition to those of Christian revelation. Fifth, the resulting dilemma means that there are true philosophical propositions, but we can't know them (scepticism), or there are no philosophical propositions and the naturalists are right (nihilism), or relativism is true. I suggest that relativism is the most palatable of these alternatives. (shrink)

Traditional philosophy relies heavily on the use of rational intuition to establish theses and conclusions. This essay takes up the matter of intuition and argues for a stunning conclusion: appeal to rational intuition is epistemically justified only if a form of foundationalism is true. This type of foundationalism is the thesis that there is at least one proposition whose justification depends on nothing other than itself. The article also argues that unless we can establish that some intuitions are justified, philosophy (...) as an enterprise that provides non-empirical knowledge is impossible. Not to put too fine a point on it then: philosophy is possible only if foundationalism is true. Whether this should be construed as the strongest possible defense of foundationalism, or the greatest objection to the pretensions of philosophy is left to the reader. (shrink)

In this paper, I am going to offer a reconstruction of a challenge to intuition-based armchair philosophy that has been put forward by experimental philosophers of a restrictionist stripe, which I will call the 'master argument'. I will then discuss a number of popular objections to this argument and explain why they either fail to cast doubt on its first, empirical premise or do not go deep enough to make for a lasting rebuttal. Next, I will consider two more promising (...) objections, the grounding objection and the expertise objection, which aim at the second, epistemic premise of the argument. Against this background, I will then suggest what I call 'conservative restrictionism' as the most reasonable default reaction to the experimentalist challenge, which is a combination of the two views of local restrictionism and methodological conservativism.

Experimental philosophy is one of the most recent and controversial developments in philosophy. Its basic idea is rather simple: to test philosophical thought experiments and philosophers’ intuitions about them with scientific methods, mostly taken from psychology and the social sciences. The ensuing experimental results, such as the cultural relativity of certain philosophical intuitions, has engaged – and at times infuriated – many more traditionally minded "armchair" philosophers since then. In this volume, the metaphilosophical reflection on experimental philosophy is brought yet (...) another step forward by engaging some of its most renowned proponents and critics in a lively and controversial debate. In addition to that, the volume also contains original experimental research on personal identity and philosophical temperament, as well as state-of-the-art essays on central metaphilosophical issues, like thought experiments, the nature of intuitions, or the status of philosophical expertise. -/- This book was originally published as a special issue of Philosophical Psychology.

What are philosophical intuitions? There is a tension between two intuitive criteria. On the one hand, many of our ordinary beliefs do not seem intuitively to be intuitions; this suggests a relatively restrictionist approach to intuitions. (A few attempts to restrict: intuitions must be noninferential, or have modal force, or abstract contents.) On the other hand, it is counterintuitive to deny a great many of our beliefs—including some that are inferential, transparently contingent, and about concrete things. This suggests a liberal (...) conception of intuitions. I defend the liberal view from the objection that it faces intuitive counterexamples; central to the defense is a treatment of the pragmatics of ‘intuition’ language: we cite intuitions, instead of directly expressing our beliefs via assertion, when we are attempting to avoid begging questions against certain sorts of philosophical interlocutors. (shrink)

I critically evaluate Ernest Sosa's (2007) contrast between intuitive justification and perceptual justification. I defend a competence-based approach to intuitive justification that is continuous with epistemic justification generally.

A number of philosophers have recently suggested that the role of intuitions in the epistemology of armchair philosophy has been exaggerated. This suggestion is rehearsed and endorsed. What bearing does the rejection of the centrality of intuition in armchair philosophy have on experimentalist critiques of the latter? I distinguish two very different kinds of experimentalist critique: one critique requires the centrality of intuition; the other does not.

What sorts of things are the intuitions generated via thought experiment? Timothy Williamson has responded to naturalistic skeptics by arguing that thought-experiment intuitions are judgments of ordinary counterfactuals. On this view, the intuition is naturalistically innocuous, but it has a contingent content and could be known at best a posteriori. We suggest an alternative to Williamson's account, according to which we apprehend thought-experiment intuitions through our grasp on truth in fiction. On our view, intuitions like the Gettier intuition are necessarily (...) true and knowable a priori. Our view, like Williamson's, avoids naturalistic skepticism. (shrink)

While engaged in the analysis of topics such as the nature of knowledge, meaning, or justice, analytic philosophers have traditionally relied extensively on their own intuitions about when the relevant terms can, and can't, be correctly applied. Consequently, if intuitions about possible cases turned out not to be a reliable tool for the proper analysis of philosophically central concepts, then a radical reworking of philosophy's (or at least analytic philosophy's) methodology would seem to be in order. It is thus not (...) surprising that the increasingly critical scrutiny that intuitions have received of late has produced what has been referred to as a "crisis" in analytic philosophy. This paper will argue, however, that at least those criticisms that stem from recent work on semantic externalism are not as serious as their proponents have claimed. Indeed, this paper will argue while the conceptual intuitions (and the analyses that result from them) will have to be recognized as fallible, they still have a prima facie claim to correctness. A naturalistic and externalistic account of concepts thus merely requires that the methodology of conceptual analysis be reinterpreted (from a 'Platonic' to a 'constructive' model) rather than given up.

This paper examines the relationship between methodological naturalism and the standard practice within philosophy of constructing theories on the basis of our intuitions about imaginary cases, especially in the work of Alvin Goldman. It is argued that current work in cognitive science presents serious problems for Goldman's approach.

This paper addresses the definition and the operational use of intuitions in philosophical methods in the form of a research study encompassing several regions of the globe, involving 282 philosophers from a wide array of academic backgrounds and areas of specialisation. The authors tested whether philosophers agree on the conceptual definition and the operational use of intuitions, and investigated whether specific demographic variables and philosophical specialisation influence how philosophers define and use intuitions. The results obtained point to a number of (...) significant findings, including that philosophers distinguish between intuitions used to formulate (discovery) and to test (justification) philosophical theory. The survey results suggest that strategies implemented to characterise philosophical intuition are not well motivated since, even though philosophers do not agree on a single account of intuition, they fail to capture a preferred usage of intuitions as aspects of discovery. The quantitative summary of survey findings informs the debate on this topic, and advances more defined routes for subsequent approaches to the study of intuitions. (shrink)

In Naming and Necessity, Kripke argues that intuitions about what is possible play a limited, but important, role in challenging philosophical theses, counting as evidence against them only if they cannot be reconstrued as intuitions about something else, compatible with the thesis in question. But he doesn't provide clear guidelines for determining when such intuitions have been successfully reconstrued, leading some to question their status as evidence for modal claims. In this paper I focus on some worries, articulated by Michael (...) Della Rocca, about whether modal intuitions can be evidence for claims about essential properties, and argue that there is a way of viewing the role of modal intuition in philosophical argument that can preserve their evidential force. (shrink)

Philosophers have traditionally held that claims about necessities and possibilities are to be evaluated by consulting our philosophical intuitions; that is, those peculiarly compelling deliverances about possibilities that arise from a serious and reflective attempt to conceive of counterexamples to these claims. But many contemporary philosophers, particularly naturalists, argue that intuitions of this sort are unreliable, citing examples of once-intuitive, but now abandoned, philosophical theses, as well as recent psychological studies that seem to establish the general fallibility of intuition.In the (...) first two sections of this paper, I evaluate these arguments, and also the counter-arguments of contemporary defenders of tradition. In the next two sections, I sketch an alternative account of the role of philosophical intuitions that incorporates elements of traditionalism and naturalism - and defend it against other such views. In the final section, however, I discuss intuitions about conscious experience, and acknowledge that my view may not extend comfortably to this case. This may seem unfortunate, since so much contemporary discussion of the epistemology of modality seems motivated by worries about the mind-body problem, and informed by the position one wishes to endorse. But, as I argue, if conscious experience is indeed an exception to the view I suggest in this paper, it is an exception that proves - and can illuminate - the rule. (shrink)

In recent years, a number of philosophers have conducted empirical studies that survey people's intuitions about various subject matters in philosophy. Some have found that intuitions vary accordingly to seemingly irrelevant facts: facts about who is considering the hypothetical case, the presence or absence of certain kinds of content, or the context in which the hypothetical case is being considered. Our research applies this experimental philosophical methodology to Judith Jarvis Thomson's famous Loop Case, which she used to call into question (...) the validity of the intuitively plausible Doctrine of Double Effect. We found that intuitions about the Loop Case vary according to the context in which the case is considered. We contend that this undermines the supposed evidential status of intuitions about the Loop Case. We conclude by considering the implications of our findings for philosophers who rely on the Loop Case to make philosophical arguments and for philosophers who use intuitions in general. (shrink)

In this paper, I defend a non-skeptical intuitionist approach to moral epistemology from recent criticisms. Starting with Sinnott-Armstrong's skeptical attacks, I argue that a familiar sort of skeptical argument rests on a problematic conception of the evidential grounds of our moral judgments. The success of his argument turns on whether we conceive of the evidential grounds of our moral judgments as consisting entirely of non-normative considerations. While we cannot avoid skepticism if we accept this conception of our evidential grounds, that's (...) because accepting this conception of our evidential grounds is tantamount to accepting the skeptic's conclusion. We have nothing to fear from arguments for skepticism from skepticism. (shrink)

There has been a movement recently to bring to bear on the conduct of philosophical thought experiments (henceforth “thought experiments”)1 the empirical techniques of the social sciences, that is, to treat their conduct as in the nature of an anthropological investigation into the application conditions of the concepts of a group of subjects. This is to take a third person, in contrast to the traditional first person, approach to conceptual analysis. This has taken the form of conducting surveys about scenarios (...) used in thought experiments.2 It has been called “experimental philosophy” by its practitioners and has been applied across a range of fields: the philosophy of language, the philosophy of action, the philosophy of mind, epistemology, and ethics.3 The results of these surveys have been used to support conclusions about the application conditions of particular concepts of interest in philosophy. They have also been used to support (and been motivated by) skeptical claims about the traditional approach to conceptual analysis. The.. (shrink)

It is commonly held that our intuitive judgements about imaginary problem cases are justified a priori, if and when they are justified at all. In this paper I defend this view — ‘rationalism’ — against a recent objection by Timothy Williamson. I argue that his objection fails on multiple grounds, but the reasons why it fails are instructive. Williamson argues from a claim about the semantics of intuitive judgements, to a claim about their psychological underpinnings, to the denial of rationalism. (...) I argue that the psychological claim — that a capacity for mental simulation explains our intuitive judgements — does not, even if true, provide reasons to reject rationalism. (More generally, a simulation hypothesis, about any category of judgements, is very limited in its epistemological implications: it is pitched at a level of explanation that is insensitive to central epistemic distinctions.) I also argue that Williamson’s semantic claim — that intuitive judgements are judgements of counterfactuals — is mistaken; rather, I propose, they are a certain kind of metaphysical possibility judgement. Several other competing proposals are also examined and criticized. (shrink)

It is all too common in philosophy to claim that a particular philosophical theory is mistaken because it fails to coincide with most philosophers' or normal inquirers' intuitions as represented in a particular case or counterexample. This suggests, as Alvin Goldman and Joel Pust point out, that our intuitions provide a sort of evidential basis for particular theories. Yet, the question remains as to whether this assessment is correct, and, if it is, whose intuitions (either those trained within the area (...) in question or normal inquirers) are more evidence conferring? Goldman and Pust provide a positive response to the former question and go on to argue that it is normal inquirers' intuitions that will be the most evidence-conferring. In this paper I first explain Goldman and Pust's view of the nature of intuitions and why, on their account, they are to count as evidence. Next, I argue that the evidence-conferring status of intuitions, as Goldman and Pust hold, is inherently flawed due to the inevitability of theory contamination. Also, I argue that intuitions (though theory contaminated) can be evidence-conferring by making an appeal to the intuitions of experts. Thus, intuitions can be counted as evidence, but not in the manner that Goldman and Pust maintain. (shrink)

Mathematical apriorists sometimes hold that our non-derived mathematical beliefs are warranted by mathematical intuition. Against this, Philip Kitcher has argued that if we had the experience of encountering mathematical experts who insisted that an intuition-produced belief was mistaken, this would undermine that belief. Since this would be a case of experience undermining the warrant provided by intuition, such warrant cannot be a priori. I argue that this leaves untouched a conception of intuition as merely an aspect of our ordinary ability (...) to reason. Thus the apriorist may still hold that some mathematical beliefs are warranted by intuition. I would like to thank an anonymous referee for Philosophia Mathematica and an audience at the Spring 2006 Long Island Philosophy Society/New Jersey Regional Philosophical Association conference for helpful comments.

Explaining intuitions in terms of "facts of our natural history" is compatible with rationally trusting them. This compatibilist view is defended in the present paper, focusing upon nomic and essentialist modal intuitions. The opposite, incompatibilist view alleges the following: If basic modal intuitions are due to our cognitive make-up or "imaginative habits" then the epistemologists are left with a mere non-rational feeling of compulsion on the side of the thinker. Intuitions then cannot inform us about modal reality. In contrast, the (...) paper argues that there are several independent sources of justification which make the feeling of compulsion rational: the prima-facie and a priori ones come from the obviousness of our basic modal intuitions and our not being able to imagine things otherwise, others, a posteriori, from the epistemic success of these intuitions. Further, the general scheme of evolutionary learning is reliable, reliability is preserved in the resulting individual's cognitive make-up, and we can come to know this a posteriori. The a posteriori appeal to evolution thus plays a subsidiary role in justification, filling the remaining gap and removing the residual doubt. Explaining modal intuitions is compatible with moderate realism about modality itself. (shrink)

The paper defends causal explanationism concerning our modal intuitions and judgments, and, in particular, the following claims. If a causally explainable mirroring or pre-established harmony between our mind and modal reality obtains, we are justified in believing it does. We do not hold our modal beliefs compulsively and blindly but with full subjective and objective justification. Therefore, causal explanation of our modal beliefs does not undermine rational trust in them. Explanation and trust support each other. In contrast, anti-explanationists (from Kant, (...) through neo-wittgensteinians to T. Nagel and J. Pust), claim that causal explanation of intuitions and judgments undermines rational trust in them. They especially target causal explanation in terms of pre-established harmony between our mind, shaped by causal processes, and the underlying modal structure of reality. The paper argues against them. The argument builds upon the claim that the appeal to modal facts is indispensable for systematization and explanation of non-modal ones. Therefore, we should assume that modal facts exist and are not disjoint and isolated from actual facts. The modal structure of the universe intervenes in the non-modal reality. Causal processes indirectly carry information about deep modal structure. Any (reasonable candidate) causal explanation of our intuitional modal beliefs should start from this indirect contact with and information about modal facts. Therefore, if our intuitional modal beliefs are true and causally explainable (by a factual, non-modal explanans), they are true in virtue of the deep underlying modal structure. They are sensitive to modal reality and track it. We can come to know this fact, and thus strengthen our spontaneous trust in our modal intuitions. (shrink)

In this paper, I argue that appeals to intuition are weak arguments because intellectual intuition is an unreliable belief-forming process, since it yields incompatible verdicts in response to the same cases, and since the inference from 'It seems to S that p' to 'p' is unreliable. Since the reliability of intellectual intuition is a necessary condition for strong appeals to intuition, it follows that appeals to intuition are weak arguments.

In this paper, I argue that appeals to intuition are strong arguments just in case there is an agreement among the relevant philosophers concerning the intuition in question. Otherwise, appeals to intuition are weak arguments.

In a series of recent papers, Walter Sinnott-Armstrong has used findings in social psychology to put pressure on the claim that our moral beliefs can be non-inferentially justified. More specifically, he has suggested that insofar as our moral intuitions are subject to what psychologists call framing effects, this poses a real problem for moral intuitionism. In this paper, we are going to try to add more fuel to the empirical fire that Sinnott-Armstrong has placed under the feet of the intuitionist. (...) Along the way, we first provide an overview of what Sinnott-Armstrong calls the Master Argument against intuitionism. Then we examine some of the literature on framing effects—especially as it pertains to moral philosophy. Finally, we present the results of a new study which create yet another hurdle intuitionists must clear if they want to motivate their view. It appears that in addition to being influenced by framing effects, our moral intuitions are also influenced by an actor–observer bias as well—a bias whereby we hold other people to different moral standards than we would hold ourselves even if we were in the same situation. If we’re right, the burden is on the moral intuitionist to explain why we should have faith in our moral intuitions despite the gathering evidence concerning their seeming unreliability. And by our lights, this is something that simply cannot be done from the armchair. (shrink)

Many epistemologists use intuitive responses to particular cases as evidence for their theories. Recently, experimental philosophers have challenged the evidential value of intuitions, suggesting that our responses to particular cases are unstable, inconsistent with the responses of the untrained, and swayed by factors such as ethnicity and gender. This paper presents evidence that neither gender nor ethnicity influence epistemic intuitions, and that the standard responses to Gettier cases and the like are widely shared. It argues that epistemic intuitions are produced (...) by the natural ‘mindreading’ capacity that underpins ordinary attributions of belief and knowledge in everyday social interaction. Although this capacity is fallible, its weaknesses are similar to the weaknesses of natural capacities such as sensory perception. Experimentalists who do not wish to be skeptical about ordinary empirical methods have no good reason to be skeptical about epistemic intuitions. (shrink)
