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.

This paper explicates Descartes’ theory of intuition (intuitus). Departing from certain commentators, I argue that intuition, for Descartes, is a form of clear and distinct intellectual perception. Because it is clear and distinct, it is indubitable, infallible, and provides a grade of certain knowledge he calls ‘cognitio’. I pay special attention to why he treats intuition as a form of perception, and what he means when he says it is ‘clear and distinct’. Finally, I situate his view in relation to (...) those of his Scholastic predecessors on one hand and current theories on the other. His view anticipates the contemporary ‘perceptual model of intuition’, though it is much bolder with its promise of certainty. (shrink)

I defend normative realism—the claim that there are mind-independent, absolute normative facts—mostly by arguing against its rivals. Against mind-dependent theories of normativity, I argue that at least one highly influential version of such a view, Lewis's dispositional theory of value, is subject to at least three severe problems: the problem of the implausible contingency of value, the problem of ideal conditions, and the problem of lack of convergence. Against relativistic conceptions of normativity, I argue that either they fail to evade (...) a commitment to absolute normative truths, or they fail to distinguish themselves from Nihilism. Finally, against Nihilism, I argue that it is not a coherent option at least for the normative domain of rationality, since facts about rationality are presupposed by any judgment, including any judgment meant to express a skepticism about facts about rationality.

In Objects: Nothing Out of the Ordinary, Daniel Z. Korman defends a view he calls conservatism. Conservatives hold that there are ordinary objects, but no extraordinary objects. But Korman never explicitly characterizes what would qualify an object as ordinary in the relevant sense. We have some paradigm cases of ordinary objects, including tables, dogs, and trees; and we have some paradigm cases of extraordinary objects of sorts familiar from the philosophical literature. Here I attempt to fill this gap, surveying a (...) number of attempts to characterize the commitments of conservatism. All fail. In particular, no specification of what it takes for an object to be ordinary is both plausible and consistent with the conservative verdicts on the paradigms. I argue that this is no coincidence, since it turns out to be implausible in light of the results of settled science to deny the existence of one of Korman's paradigms of an extraordinary object. The upshot is that plausibility requires being a little more liberal than conservatism seems to allow. (shrink)

George Bealer provides an account of intuitions as “intellectual seemings.” My purpose in this paper is to criticize the phenomenological considerations that Bealer offers in favor of his account. In the first part I review Bealer’s attempt to distinguish intuitions from beliefs, judgments, guesses, and hunches. I examine each of the three phenomenological differences – incorrigibility, implasticity, and scope – that Bealer adduces between intuitions and these other types of mental contents. I argue that any difference between intuitions and these (...) other types of mental contents with regards to their incorrigibility, implasticity, and scope is unproven and likely to remain unproven. In the second part I criticize Bealer’s analogy between intuitions and sensory seemings by suggesting that intuitions do not display the theoretical virtues—consistency, corroboration, and confirmation—that Bealer claims for them. Moreover, I suggest that intuitions do not display the theoretical virtue that would indicate a similarity to sensory seemings, consilience. (shrink)

We develop an argument for a novel version of moral intuitionism centered on the claim that moral intuitions are trustworthy. Our argument employs an epistemic principle that we call the Trustworthiness Criterion, a distinctive feature of which is its emphasis on oft-neglected social dimensions of cognitive states, including non-doxastic attitudes such as intuition. Thus our argument is not that moral intuitions are trustworthy because they are regress-stoppers, or because they are innocent until proven guilty, or because denying their epistemic contribution (...) would be self-defeating, or because they are presupposed in rational inference, or because they are analogous to perceptions, or because they are based on understanding—individualistic claims that have elsewhere been used (controversially) in defense of the thesis that moral intuitions are in good epistemic standing. Rather, our argument appeals to the idea that moral intuitions are trustworthy because they are the outputs of a cognitive practice, which has epistemically-fecund social elements, that is in good working order.

Approaching Infinity addresses seventeen paradoxes of the infinite, most of which have no generally accepted solutions. The book addresses these paradoxes using a new theory of infinity, which entails that an infinite series is uncompletable when it requires something to possess an infinite intensive magnitude. Along the way, the author addresses the nature of numbers, sets, geometric points, and related matters. The book addresses the need for a theory of infinity, and reviews both old and new theories of infinity. It (...) discussing the purposes of studying infinity and the troubles with traditional approaches to the problem, and concludes by offering a solution to some existing paradoxes. (shrink)

Segundo um influente argumento contra a existência de conhecimento a priori, não há conhecimento a priori porque (i) nenhuma crença é imune à revisão, e (ii) se houvesse conhecimento a priori, algumas crenças seriam irrevisíveis. Uma versão deste argumento foi celebremente defendida por W. V. Quine e ainda é popular entre filósofos naturalistas. O objectivo deste artigo é examinar e rejeitar este argumento contra o a priori. O artigo começa por discutir a tese (i) e o seu papel no modelo (...) da Teia de Crenças de Quine. Defende-se que (i) enfrenta importantes desafios que colocam em risco o seu uso no argumento supra. A premissa (ii) do argumento é então discutida. Philip Kitcher é conhecido pela sua defesa de uma versão da premissa (ii). Os seus argumentos são analisados e rejeitados. A conclusão é que não temos uma boa razão para aceitar (ii), e consequentemente este argumento contra o a priori. O artigo termina com a proposta de uma caracterização do a priori perfeitamente compatível com (i). (shrink)

Van Fraassen has argued that many philosophical positions should be understood as stances rather than factual beliefs. In this paper I discuss the vexed question of whether and how such stances can be rationally justified. Until this question has been satisfactorily answered, the otherwise promising stance approach cannot be considered a viable metaphilosophical option. One can find hints, and the beginnings of an answer to this question, in van Fraassen’s (and others’) writings, but no general, fully clear and convincing account (...) has been offered. I aim to provide such an account. In the first section I introduce the concept of a stance. In the second section I argue that stances may be justified pragmatically, in terms of both their epistemic fruits, and their coherence with values. In the third section I further consider the relationship between stances and values, arguing that the value-ladenness of a stance does not render it immune to rational scrutiny. In the final section I look at van Fraassen’s version of epistemological voluntarism, which plays a central role in his conception of the basis on which a stance may be rationally adopted. I show that voluntarism provides a theoretical framework, and approach to epistemology, within which the forms of justification appropriate to stance choice I outline in sections 2 and 3 find a natural home.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (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)

Evidential holism begins with something like the claim that “it is only jointly as a theory that scientific statements imply their observable consequences.” This is the holistic claim that Elliott Sober tells us is an “unexceptional observation”. But variations on this “unexceptional” claim feature as a premise in a series of controversial arguments for radical conclusions, such as that there is no analytic or synthetic distinction that the meaning of a sentence cannot be understood without understanding the whole language of (...) which it is a part and that all knowledge is empirical knowledge. This paper is a survey of what evidential holism is, how plausible it is, and what consequences it has. Section 1 will distinguish a range of different holistic claims, Sections 2 and 3 explore how well motivated they are and how they relate to one another, and Section 4 returns to the arguments listed above and uses the distinctions from the previous sections to identify holism's role in each case.

Rationalists often argue that empiricism is incoherent and conclude, on that basis, that some knowledge is a priori. I contend that such arguments against empiricism cannot be parlayed into an argument in support of the a priori since rationalism is open to the same arguments. I go on to offer an alternative strategy. The leading idea is that, instead of offering a priori arguments against empiricism, rationalists should marshal empirical support for their position.

Debunking skeptics claim that our moral beliefs are formed by processes unsuited to identifying objective facts, such as emotions inculcated by our genes and culture; therefore, they say, even if there are objective moral facts, we probably don’t know them. I argue that the debunking skeptics cannot explain the pervasive trend toward liberalization of values over human history, and that the best explanation is the realist’s: humanity is becoming increasingly liberal because liberalism is the objectively correct moral stance.

Intuition is sometimes derided as an abstruse or esoteric phenomenon akin to crystal-ball gazing. Such derision appears to be fuelled primarily by the suggestion, evidently endorsed by traditional rationalists such as Plato and Descartes, that intuition is a kind of direct, immediate apprehension akin to perception. This paper suggests that although the perceptual analogy has often been dismissed as encouraging a theoretically useless metaphor, a quasi-perceptualist view of intuition may enable rationalists to begin to meet the challenge of supplying a (...) theoretically satisfying treatment of their favoured epistemic source. It is argued, first, that intuitions and perceptual experiences are at a certain level of abstraction the same type of mental state, presentations, which are distinct from beliefs, hunches, inclinations, attractions, and seemings. The notion of a presentation is given a positive explication, which identifies its characteristic features, accounts for several of its substantive psychological roles, and systematically locates it in a threefold division among types of contentful states. Subsequently, it is argued that presentations, intuitive no less than sensory, are by their nature poised to play a distinctive epistemic role. Specifically, in the case of intuition, we encounter an intellectual state that is so structured as to provide justification without requiring justification in turn—something which may, thus, be thought of as ‘given’.

A lot of good philosophy is done in the armchair, but is nevertheless a posteriori. This paper clarifies and then defends that claim. Among the a posteriori activities done in the armchair are assembling and evaluating commonplaces; formulating theoretical alternatives; and integrating well-known past a posteriori discoveries. The activity that receives the most discussion, however, is the application of theoretical virtues to choose philosophical theories: the paper argues that much of this is properly seen as a posteriori.

In Philosophy Without Intuitions, Herman Cappelen focuses on the metaphilosophical thesis he calls Centrality: contemporary analytic philosophers rely on intuitions as evidence for philosophical theories. Using linguistic and textual analysis, he argues that Centrality is false. He also suggests that because most philosophers accept Centrality, they have mistaken beliefs about their own methods.To put my own views on the table: I do not have a large theoretical stake in the status of intuitions, but unreflectively I find it fairly obvious that (...) many philosophers, including myself, appeal to intuitions. Cappelen’s arguments make a provocative challenge to this unreflective background conception. So it is interesting to work through the arguments to see what they might and might not show.In what follows I aim to articulate a minimal notion of intuition that captures something of the core everyday philosophical usage of the term, and that captures the sense ..

Since van Fraassen first put forward the suggestive idea that many philosophical positions should be construed as ‘stances’ rather than factual beliefs, there have been various attempts to spell out precisely what a philosophical stance might be, and on what basis one should be adopted. In this paper I defend a particular account of stances, the view that they are pragmatically justified perspectives or ways of seeing the world, and compare it to some other accounts that have been offered. In (...) Sect. 2 I consider van Fraassen’s argument for construing empiricism as a stance, and look at some responses to it. In Sect. 3 I outline my conception of stances as perspectives or ways of seeing, and explain how stances so understood may be justified. I illustrate this conception by way of a discussion of the model pluralist position with respect to the units of selection debate in biology, and suggest that on the model pluralist view different perspectives on the units of selection, such as the gene’s eye view, are in fact van Fraassian stances. In Sect. 4 I discuss the view put forward by Teller and Chakravartty among others that stances should be understood as epistemic policies, and argue that it is consistent with the conception of stances as perspectives. In the final section I criticise Rowbottom’s attempt to assimilate stances to Kuhnian paradigms. I argue that he has overlooked some important disanalogies between stances and paradigms, so that the comparison obscures more than it reveals. (shrink)

In this thesis I seek to advance our understanding of what intuitions are. I argue that intuitions are experiences of a certain kind. In particular, they are experiences with representational content, and with a certain phenomenal character. -/- In Chapter 1 I identify our target and provide some important reliminaries. Intuitions are mental states, but which ones? Giving examples helps: a person has an intuition when it seems to her that torturing the innocent is wrong, or that if something is (...) red it is coloured. We can also provide an initial characterisation of the state by saying that it has representational content, often causes belief, and appears to justify belief. In addition, there is something it is like to have an intuition: intuition has a certain phenomenal character. -/- Some argue that intuition does not explain anything which cannot be explained by other mental states. One version of this view takes intuition to reduce to belief. In Chapter 2 I argue that this entails that agents are rationally criticisable in situations where we know they are not, and that such views are therefore untenable. A parallel argument shows that the corresponding approach to perception fails. This suggests a similarity in nature: both intuition and perception are experiences. -/- Others take intuition to reduce to a disposition to have a belief. In Chapter 3 I consider a line of argument against such views, find it unsuccessful, and present two new arguments. One is likely to be dialectically ineffective. The other suffers no such weakness: it shows that the proposed reduction fails. As before, the argument also applies to perception, and suggests that intuition and perception are both experiences. -/- In the remainder of the thesis I develop an account of intuition as an experience. I distinguish between content-specific and attitude-specific phenomenology, and argue that intuition lacks the former (Chapter 4), but has the latter (Chapter 5). This allows us to say what intuition is: it is is an experience with representational content and with attitude-specific phenomenology of a certain kind. -/- In Chapter 6 I put this account of intuition to use. When a person has a perceptual or intuitional experience, I argue that simply having the experience is what makes the subject justified in believing what the experience represents. Moreover, what explains that intuition and perception can justify belief in this way is precisely their phenomenal character. (shrink)

In this paper I will argue that this entire dialectic is somewhat misguided. The mental states which are generally assumed to fall under the category of ‘intuition’ likely comprise a highly heterogeneous group; from the point of view of psychology or of neuroscience, in fact, ‘intuitions’ appear to be generated by several fundamentally different sorts of mental processes. If this is correct, then the term ‘intuition’ may simply carve things too broadly. I will argue that it is a mistake to (...) focus on the ‘reliability of intuition’; empirical evidence suggests that the reliability of one type of intuition may tell us next to nothing about the reliability of other types. Rather than debating the evidential status of intuition as a whole, philosophers interested in methodology would do well to focus their investigations much more narrowly. (shrink)

It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there (...) is no relevant counterevidence. This piece is an introduction to a volume dedicated to the question of what the connection is between seemings and justified belief: under what conditions, if any, can a seeming justify its content?

Intuitions play an important role in contemporary philosophy. It is common for theories in epistemology, morality, semantics and metaphysics to be rejected because they are inconsistent with a widely and firmly held intuition. Our goal in this paper is to explore the role of epistemic intuitions in epistemology from a naturalistic perspective. Here is the question we take to be central: (Q) Ought we to trust our epistemic intuitions as evidence in support of our epistemological theories? We will understand this (...) question as employing an epistemic ‘ought’ – insofar as we aim at developing a correct epistemological theory, ought we to trust our epistemic intuitions as evidence for or against our epistemological theories? As it stands, (Q) needs further clarification. Whether something is trustworthy is relative to what (a) what it is and (b) what we’re asking it to do. Sam might trust Marie but not George to care for his children, while he might trust both to care for his pet fish. So in order to address (Q), we first need to explore two questions: What are epistemic intuitions? And what sort of epistemological theories do we want? We will take up each of these questions in the following sections. (shrink)

Skepticism about the epistemic value of intuition in theoretical and philosophical inquiry has recently been bolstered by empirical research suggesting that people’s concrete-case intuitions are vulnerable to irrational biases (e.g., the order effect). What is more, skeptics argue that we have no way to ‘‘calibrate” our intuitions against these biases and no way of anticipating intuitional instability. This paper challenges the skeptical position, introducing data from two studies that suggest not only that people’s concrete-case intuitions are often stable, but also (...) that people have introspective awareness of this stability, providing a promising means by which to assess the epistemic value of our intuitions. (shrink)

This paper poses a constructive, evenhanded challenge to the idea that recent experimental work shows intuitions to be epistemically problematic. It is a challenge because it suggests that these experimental attacks neglect a considerable gap between intuitions and answers, and this neglect implies that we are at the present time unwarranted in drawing any negative conclusions about intuition’s epistemic status from the relevant empirical studies. The challenge is evenhanded because it does not load the dice by invoking an overly narrow (...) conception of intuition. Finally, the challenge is constructive: it is not an exercise in idle skepticism, but rather explores concrete implications and applications. These include (i) a practical lesson that may help experimentalists in their efforts to study intuitions empirically, (ii) methodological counsel that may help rationalists in their efforts to intuit responsibly, and (iii) a novel explanation of the relevant empirical studies that may actually support rather than undermine intuition’s epistemic status—perhaps, however, to the detriment of the epistemic status of answers.

In the standard thought experiments, dualism strikes many philosophers as true, including many non-dualists. This ‘striking’ generates prima facie justification: in the absence of defeaters, we ought to believe that things are as they seem to be, i.e. we ought to be dualists. In this paper, I examine several proposed undercutting defeaters for our dualist intuitions. I argue that each proposal fails, since each rests on a false assumption, or requires empirical evidence that it lacks, or overgenerates defeaters. By the (...) end, our prima facie justification for dualism remains undefeated. I close with one objection concerning the dialectical role of rebutting defeaters, and I argue that the prospects for a successful rebutting defeater for our dualist intuitions are dim. Since dualism emerges undefeated, we ought to believe it. (shrink)

An argument is epistemically self-defeating when either the truth of an argument’s conclusion or belief in an argument’s conclusion defeats one’s justification to believe at least one of that argument’s premises. Some extant defenses of the evidentiary value of intuition have invoked considerations of epistemic self-defeat in their defense. I argue that there is one kind of argument against intuition, an unreliability argument, which, even if epistemically self-defeating, can still imply that we are not justified in thinking intuition has evidentiary (...) value. (shrink)

A simple reductive view of intuition holds that intuition is a type of belief. That an agent who intuits that p sometimes believes that p is false is often thought to demonstrate that the simple reductive view is false. I show that this argument is inconclusive, but also that an argument for the same conclusion can be rebuilt using the notion of rational criticisability. I then use that notion to argue that perception is also not reducible to belief, and that (...) neither intuition nor perception is reducible to credence. (shrink)

Begins by explaining then proving a generalized language dependence result similar to Goodman's "grue" problem. I then use this result to cast doubt on the existence of an objective evidential favoring relation (such as "the evidence confirms one hypothesis over another," "the evidence provides more reason to believe one hypothesis over the other," "the evidence justifies one hypothesis over the other," etc.). Once we understand what language dependence tells us about evidential favoring, our options are an implausibly strong conception of (...) the a priori, a hard externalism on which agents are unable to determine what their evidence favors, or a subjectivist view that makes evidential favoring relative to features of the agent.

In this paper I develop three different arguments against the thesis that knowledge-how is a kind of knowledge-that. Knowledge-that is widely thought to be subject to an anti-luck condition, a justified or warranted belief condition, and a belief condition, respectively. The arguments I give suggest that if either of these standard assumptions is correct then knowledge-how is not a kind of knowledge-that. In closing I identify a possible alternative to the standard Rylean and intellectualist accounts of knowledge-how. This alternative view (...) illustrates that even if the arguments given here succeed it might still be reasonable to hold that knowing how to do something is a matter of standing in an intentional relation to a proposition other than the knowledge-that relation.

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)

Strategic Reliabilism is a framework that yields relative epistemic evaluations of belief-producing cognitive processes. It is a theory of cognitive excellence, or more colloquially, a theory of reasoning excellence (where 'reasoning' is understood very broadly as any sort of cognitive process for coming to judgments or beliefs). First introduced in our book, Epistemology and the Psychology of Human Judgment (henceforth EPHJ), the basic idea behind SR is that epistemically excellent reasoning is efficient reasoning that leads in a robustly reliable fashion (...) to significant, true beliefs. It differs from most contemporary epistemological theories in two ways. First, it is not a theory of justification or knowledge – a theory of epistemically worthy belief. Strategic Reliabilism is a theory of epistemically worthy ways of forming beliefs. And second, Strategic Reliabilism does not attempt to account for an epistemological property that is assumed to be faithfully reflected in the epistemic judgments and intuitions of philosophers. If SR makes recommendations that accord with our reflective epistemic judgments and intuitions, great. If not, then so much the worse for our reflective epistemic judgments and intuitions. (shrink)

Zombies are bodies without minds: creatures that are physically identical to actual human beings, but which have no conscious experience. Much of the consciousness literature focuses on considering how threatening philosophical reflection on such creatures is to physicalism. There is not much attention given to the converse possibility, the possibility of minds without bodies, that is, creatures who are conscious but whose nature is exhausted by their being conscious. We can call such a ‘purely conscious’ creature a ghost.

Experimental philosophy has emerged as a very specific kind of response to an equally specific way of thinking about philosophy, one typically associated with philosophical analysis and according to which philosophical claims are measured, at least in part, by our intuitions. Since experimental philosophy has emerged as a response to this way of thinking about philosophy, its philosophical significance depends, in no small part, on how significant the practice of appealing to intuitions is to philosophy. In this paper, I defend (...) the significance of experimental philosophy by defending the significance of intuitions—in particular, by defending their significance from a recent challenge advanced by Timothy Williamson.

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)

The paper elaborates upon various points and arguments in the author’s “A Priori Knowledge and the Scope of Philosophy” (Philosophical Studies, 1993), in which the author defends the autonomy of philosophy from the empirical sciences. It provides, for example, an extended defense of the modal reliabilist theory of basic evidence, including a new argument against evolutionary explanations of the reliability of intuitions. It also contains a fuller discussion of how to neutralize the threat of scientific essentialism to the autonomy of (...) philosophy. (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 misunderstanding of one's concepts . 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 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 are ultimately self-defeating. (shrink)

Descartes has a Clarity First epistemology: (i) Clarity is a primitive (indefinable) phenomenal quality: the appearance of truth. (ii) Clarity is prior to other qualities: obscurity, confusion, distinctness – are defined in terms of clarity; epistemic goods – reason to assent, rational inclination to assent, reliability, and knowledge – are explained by clarity. (This is the first of two companion entries; the sequel is called, "Descartes's Method for Achieving Knowledge.").

This compilation of references includes all references for the knowledge-how chapters included in Bengson & Moffett's edited volume. The volume and the compilation of references may serve as a good starting point for people who are unfamiliar with the philosophical literature on knowledge-how.

Brentano clearly asserts, in his Vienna lectures of 1887–1888, that his descriptive psychology is an a priori or “exact” science. Since he rejects Kant's idea of a synthetic a priori, this means that the descriptive psychologist's laws are analytic. My aim in this paper is to clarify and discuss this view. I examine Brentano's epistemology in the Psychology from an Empirical Standpoint and then its later developments. I conclude with a difficulty inherent in Brentano's psychological approach to a priori knowledge.

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. (shrink)

The traditional epistemological approach towards judgments like BACHELORS ARE UNMARRIED or ALL KNOWLEDGE IS TRUE is that they are justified or known on the basis of understanding alone. In this paper, I develop an understanding-based account which takes understanding to be a sufficient source of epistemic justification for the relevant judgments. Understanding-based accounts face the problem of the rational revisability of almost all human judgments. Williamson has recently developed a reinforced version of this problem: the challenge from expert revisability. This (...) is the problem that even the best candidate judgments for understanding-based justification can be rationally rejected by the relevant experts, who may not even have any disposition or inclination to accept these judgments. However, I argue that expert revisability is fully compatible with the proposed understanding-based epistemology, because expert revisability is true of sufficient sources of epistemic justification in general. A remaining metaphysical worry is that understanding might end up being ‘too thin’ to play the envisaged epistemological role. This worry can be countered with a novel metaphysics of understanding involving second-order dispositions. (shrink)

Van Fraassen’s view that many philosophical positions should be understood as stances rather than factual beliefs with propositional content, has become increasingly popular. But the precise relation between a philosophical stance, and the factual beliefs that typically accompany it, is an unresolved issue. It is widely accepted that no factual belief is sufficient for holding a particular stance, but some have argued that holding certain factual beliefs is nonetheless necessary for adopting a given stance. I argue against this claim, along (...) with the weaker claim that while there are no beliefs that are necessary for adopting a particular stance, those who share a stance must share some characteristic belief(s) in common. I outline and defend an alternative ‘cluster’ account, according to which, in order to accept a stance, one must hold some minimal subset of the set of theoretical beliefs characteristic of the stance in question. This view can accommodate the intuitions motivating those who defend the stronger necessity claims, while crucially allowing for the flexibility of a stance vis-à-vis the relevant factual beliefs, and its relative independence from those beliefs, which is central to van Fraassen’s main examples of stances and their nature. (shrink)

Some versions of empiricism have been accused of being neither empirically confirmable nor analytically true and therefore meaningless or unknowable by their own lights. Carnap, and more recently van Fraassen, have responded to this objection by construing empiricism as a stance containing non-cognitive attitudes. The resulting stance empiricism is not subject to the norms of knowledge, and so does not self-defeat as per the objection. In response to this proposal, several philosophers have argued that if empiricism is a stance, then (...) there can be no distinctively epistemic reasons in favor of adopting it, but only prudential or moral reasons. I defend stance empiricism against this objection by showing that stance empiricism furthers many plausibly epistemic goals, such as false belief avoidance, wisdom, and justification. I respond to three objections to my argument: that I assume a conception of epistemic reason that leads to problematic tradeoffs, that to have epistemic reason is just to be epistemically justified, and that my premise that experience is the only source of information has no empirical content.

In this thesis I examine the view—known as intellectualism—that knowledge-how is a kind of knowledge-that, or propositional knowledge. I examine issues concerning both the status of this view of knowledge-how and the philosophical implications if it is true. The ability hypothesis is an important position in the philosophy of mind that appeals to Gilbert Ryle’s famous idea that there is a fundamental distinction between knowledge-how and knowledge-that. This position appears to be inconsistent with the truth of intellectualism. However, I demonstrate (...) in this thesis that the ability hypothesis can be restated using the intellectualist view of knowledge-how. With regards to the status of intellectualism, I argue that the two main traditional arguments against intellectualism do not succeed. I also provide new and, I claim, successful arguments against intellectualism. These arguments point to a new view of knowledge-how that is distinct from both the standard intellectualist and Rylean views of knowledge-how. (shrink)

From Plato to the present, intuition plays a central role in epistemology. My concern in this paper is with the nature and epistemic status of intuition. To that end, I will be reviewing both Bealer’s and Wittgenstein’s accounts of intuition. I will be arguing that by ‘intuition’ Bealer understands modal intuition that has Platonic and metaphysical roles. Subsequently, I shall also show that although Wittgenstein’s view avoids these two issues, it amounts to the idea that intuition is a normative activity (...) with a dialectical value. As a result, if Bealer and Wittgenstein are right, then intuition should no more have any epistemic and evidential role. (shrink)
