The primary aim of this paper is to defend the Lockean View—the view that a belief is epistemically justified iff it is highly probable—against a new family of objections. According to these objections, broadly speaking, the Lockean View ought to be abandoned because it is incompatible with, or difficult to square with, our judgments surrounding certain legal cases. I distinguish and explore three different versions of these objections—The Conviction Argument, the Argument from Assertion and Practical Reasoning, and the Comparative Probabilities (...) Argument—but argue that none of them are successful. I also present some very general reasons for being pessimistic about the overall strategy of using legal considerations to evaluate epistemic theories; as we will see, there are good reasons to think that many of the considerations relevant to legal theorizing are ultimately irrelevant to epistemic theorizing.

While epistemologists have long debated what it takes for beliefs to be justified, they've devoted much less collective attention to the question of what it takes for beliefs to be excused, and how excuses differ from justifications. This stands in contrast to the state of affairs in legal scholarship, where the contrast between justifications and excuses is a standard topic in introductory criminal law textbooks. My goal in this paper is to extract some lessons from legal theory for epistemologists seeking (...) to distinguish epistemic justifications from epistemic excuses. First, I'll provide a brief overview of appeals to the justification/excuse distinction in epistemology, focusing on the internalism/externalism debate. Then, I'll identify some choice points in legal theory for how to think about the function of the justification/excuse distinction, and will in turn correspond to analogous choice points in epistemology. Ultimately, I'll argue that depending on which way we go at some crucial junctures, we can motivate either a traditional, non‐factive, internalist conception of justification, or a purely factive one where truth is all that's required for a belief to be justified. But there's no clear path, via legal theory, to view that only beliefs that amount to knowledge are justified. (shrink)

Vrijednosni obrat u epistemologiji iznjedrio je posebno utjecajnu poziciju – epistemologiju vrlina. Radi se o raširenom i utjecajnom epistemološkom projektu čiji je cilj postulirati intelektualne vrline spoznavatelja, a ne istinitost propozicije, kao središnje epistemičke vrijednosti. U prvom dijelu članka kratko ćemo izložiti o kakvom se vrijednosnom obratu radi te izložiti temeljne postavke epistemologije vrline, ukazujući na raznorodnost stavova epistemologa koji su se priklonili ovom pristupu, ali i na plodno širenje epistemoloških obzora. U drugom dijelu fokusirat ćemo se na vrline epistemičke (...) odgovornosti i epistemičke pravednosti kao osobito primjerene za vrednovanje socijalnih spoznajnih procesa kao što je, primjerice, svjedočanstvo i komunikacija/konverzacija općenito. U trećem dijelu ćemo pokazati kako specifična spoznajna aktivnost – komunikacijski akt u psihijatriji i psihoterapiji – može biti analizirana i vrednovana iz perspektive vrline epistemičke pravednosti na epistemički bolji i učinkovitiji način nego što je to moguće kroz tradicionalni epistemički pristup utemeljen na monizmu istine.

In this paper, I offer an analysis of the radical disagreement over the adequacy of string theory. The prominence of string theory despite its notorious lack of empirical support is sometimes explained as a troubling case of science gone awry, driven largely by sociological mechanisms such as groupthink (e.g. Smolin 2006). Others, such as Dawid (2013), explain the controversy by positing a methodological revolution of sorts, according to which string theorists have quietly turned to nonempirical methods of theory assessment given (...) the technological inability to directly test the theory. The appropriate response, according to Dawid, is to acknowledge this development and widen the canons of acceptable scientific methods. As I’ll argue, however, the current situation in fundamental physics does not require either of these responses. Rather, as I’ll suggest, much of the controversy stems from a failure to properly distinguish the “context of justification” from the “context of pursuit”. Both those who accuse string theorists of betraying the scientific method and those who advocate an enlarged conception of scientific methodology objectionably conflate epistemic justification with judgements of pursuit-worthiness. Once we get clear about this distinction and about the different norms governing the two contexts, the current situation in fundamental physics becomes much less puzzling. After defending this diagnosis of the controversy, I’ll show how the argument patterns that have been posited by Dawid as constituting an emergent methodological revolution in science are better off if reworked as arguments belonging to the context of pursuit.

In this paper we address the question of how it can be possible for a non-expert to acquire justified true belief from expert testimony. We discuss reductionism and epistemic trust as theoretical approaches to answer this question and present a novel solution that avoids major problems of both theoretical options: Performative Expert Testimony (PET). PET draws on a functional account of expertise insofar as it takes the expert’s visibility as a good informant capable to satisfy informational needs as equally important (...) as her specific skills and knowledge. We explain how PET generates justification for testimonial belief, which is at once assessable for non-experts and maintains the division of epistemic labor between them and the experts. Thereafter we defend PET against two objections. First, we point out that the non-expert’s interest in acquiring widely assertable true beliefs and the expert’s interest in maintaining her status as a good informant counterbalances the relativist account of justification at work in PET. Second, we show that with regard to the interests at work in testimonial exchanges between experts and non-experts, PET yields a better explanation of knowledge-acquisition from expert testimony than externalist accounts of justification such as reliabilism. As our arguments ground in a conception of knowledge, which conceives of belief-justification as a declarative speech act, throughout the rearmost sections of this paper we also indicate to how such a conception is operationalized in PET.

What is the role of affective experience in explaining how our desires provide us with reasons for action? When we desire that p, we are thereby disposed to feel attracted to the prospect that p, or to feel averse to the prospect that not-p. In this paper, we argue that affective experiences – including feelings of attraction and aversion – provide us with reasons for action in virtue of their phenomenal character. Moreover, we argue that desires provide us with reasons (...) for action only insofar as they are dispositions to have affective experiences. On this account, affective experience has a central role to play in explaining how desires provide reasons for action. (shrink)

What does it mean for a hypothesis to be ad hoc? One prominent account has it that ad hoc hypotheses have no independent empirical support. Others have viewed ad hoc judgements as subjective. Here I critically review both of these views and defend my own Coherentist Conception of Ad hocness by working out its conceptual and descriptive attractions.

Thought experiments invite us to evaluate philosophical theses by making judgements about hypothetical cases. When the judgements and the theses conflict, it is often the latter that are rejected. But what is the nature of the judgements such that they are able to play this role? I answer this question by arguing that typical judgements about thought experiments are in fact judgements of normal counterfactual sufficiency. I begin by focusing on Anna-Sara Malmgren’s defence of the claim that typical judgements about (...) thought experiments are mere possibility judgements. This view is shown to fail for two closely related reasons: it cannot account for the incorrectness of certain misjudgements, and it cannot account for the inconsistency of certain pairs of conflicting judgements. This prompts a reconsideration of Timothy Williamson’s alternative proposal, according to which typical judgements about thought experiments are counterfactual in nature. I show that taking such judgements to concern what would normally hold in instances of the relevant hypothetical scenarios avoids the objections that have been pressed against this kind of view. I then consider some other potential objections, but argue that they provide no grounds for doubt. (shrink)

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

It is widely maintained that doxastic norms that govern how people should believe can be explained by the truism that belief is governed by the correctness norm: believing p is correct if and only if p. This approach fails because it confuses two kinds of correctness norm: (1) It is correct for S to believe p if and only p; and (2) believing p is correct qua belief if and only if p. Only can (2) be said to be a (...) truism about belief, but it cannot ground doxastic norms. (shrink)

Epistemic infinitism is the view that infinite series of inferential relations are productive of epistemic justification. Peirce is explicitly infinitist in his early work, namely his 1868 series of articles. Further, Peirce's semiotic categories of firsts, seconds, and thirds favors a mixed theory of justification. The conclusion is that Peirce was an infinitist, and particularly, what I will term an impure infinitist. However, the prospects for Peirce's infinitism depend entirely on the prospects for Peirce's early semantics, which are not good. (...) Peirce himself revised the semantic theory later, and in so doing, it seems also his epistemic infinitism. (shrink)

Scientific antirealists run the argument from underconsideration against scientific realism. I argue that the argument from underconsideration backfires on antirealists’ positive philosophical theories, such as the contextual theory of explanation (van Fraassen, 1980), the English model of rationality (van Fraassen, 1989), the evolutionary explanation of the success of science (Wray, 2008; 2012), and explanatory idealism (Khalifa, 2013). Antirealists strengthen the argument from underconsideration with the pessimistic induction against current scientific theories. In response, I construct a pessimistic induction against antirealists that (...) since antirealists generated problematic philosophical theories in the past, they must be generating problematic philosophical theories now.

Epistemic instrumentalists face a puzzle. In brief, the puzzle is that if the reason there is to believe in accord with the evidence depends, as the instrumentalist says it does, on agents’ idiosyncratic interests, then there is no reason to expect that this reason is universal. Here, I identify and explain two strategies instrumentalists have used to try and solve this puzzle. I then argue that we should find these strategies wanting. Faced with the failure of these strategies, I articulate (...) a heretofore neglected solution on behalf of instrumentalism. (shrink)

In recent epistemology many philosophers have adhered to a moderate foundationalism according to which some beliefs do not depend on other beliefs for their justification. Reliance on such ‘basic beliefs’ pervades both internalist and externalist theories of justification. In this article I argue that the phenomenon of perceptual learning – the fact that certain ‘expert’ observers are able to form more justified basic beliefs than novice observers – constitutes a challenge for moderate foundationalists. In order to accommodate perceptual learning cases, (...) the moderate foundationalist will have to characterize the ‘expertise’ of the expert observer in such a way that it cannot be had by novice observers and that it bestows justification on expert basic beliefs independently of any other justification had by the expert. I will argue that the accounts of expert basic beliefs currently present in the literature fail to meet this challenge, as they either result in a too liberal ascription of justification or fail to draw a clear distinction between expert basic beliefs and other spontaneously formed beliefs. Nevertheless, some guidelines for a future solution will be provided. (shrink)

The purpose of this paper is to consider Joshua Gert’s novel view of subjective practical rationality in his book Brute Rationality. After briefly outlining the account, I present two objections to his view and then consider his own objections to a rival approach to understanding subjective rationality which I take to be much more plausible.

Carroll's short piece “What the Tortoise said to Achilles” in many ways anticipates issues that arise in a number of contemporary controversies. One might argue, for example, that initially plausible attempts to deal with the problem of easy knowledge will land one in the unfortunate position of Achilles who followed the Tortoise down a road that leads to vicious infinite regress. Or consider the conditions required for inferential justification. For idealized inferential justification, I have defended the view that to be (...) justified in believing P on the basis of E one needs to be not only justified in believing E, but justified in believing that E makes probable P. And again, critics have argued that such a strong requirement fails to learn the lesson that Achilles should have been taught by the Tortoise. Even more generally, one might well argue that strong access internalists will need to deal with a variation of Carroll's puzzle even for their accounts of non-inferential justification. In this paper I'll examine these controversies with a mind to reaching a conclusion about just exactly how one can accept intellectually demanding conditions on justified belief without encountering vicious regress.

Bayesian epistemology provides a formal framework within which concepts in traditional epistemology, in particular concepts relating to the justification of our beliefs, can be given precise definitions in terms of probability. The Bayesian approach has contributed clarity and precision to a number of traditional issues. A salient example is the recent embedding of the so-called coherentist theory of epistemic justification in a Bayesian framework shedding light on the relation between coherence and truth as well as on the concept of coherence (...) itself. Starting with the early work of Condorcet, the calculus of probability has proved to be a useful tool in the study of social aspects of knowledge as it is pursued in social epistemology. (shrink)

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’.

Once upon a time, coherentism was the dominant response to the regress problem in epistemology, but in recent decades the view has fallen into disrepute: now almost everyone is a foundationalist (with a few infinitists sprinkled here and there). In this paper, I sketch a new way of thinking about coherentism, and show how it avoids many of the problems often thought fatal for the view, including the isolation objection, worries over circularity, and concerns that the concept of coherence is (...) too vague or metaphorical for serious theoretical use. The key to my approach is to take a familiar tool from discussions of the regress problem -- namely, directed graphs depicting the support relations between beliefs -- and to use that tool in a more sophisticated manner than it is standardly employed.

The epistemic poverty objection is commonly levelled by externalists against deontological conceptions of epistemic justification. This is that an “oughts” based account of epistemic justification together with “ought” implies “can” must lead us to hold to be justified, epistemic agents who are objectively not truth-conducive cognizers. The epistemic poverty objection has led to a common response from deontologists, namely to embrace accounts of bounded rationality—subjective, practical or regulative accounts rather than objective, absolute or theoretical accounts. But the bounds deontological epistemologists (...) and their opponents entertain rarely include cultural limitations. This paper considers neo-Vygotskian arguments that we must consider such cultural limits in defending deontologism, and thus that any deontologically motivated perspectivism must be in part a cultural perspectivism. The dangers of strong relativism are flagged and an attempt is made to steer a.. (shrink)

This peer-reviewed paper intervenes in debates relating to overarching themes that impact upon mass media studies, communication theory and theories of cognition more generally. In particular, the paper discusses issues involving how our ordinary psychological thinking relates to norms of rationality (and how these latter are conceived). In essence, I argue against a dominant approach taken by Christopher Peacocke, that rationality can be grounded in the possession of certain concepts. The article makes a new contribution to the field by arguing (...) against the dominant approach on two grounds: (a) it fails to distinguish between true and false normative commitments; (b) it is empirically unsound. In response, I briefly offer suggestions towards an alternative, and psychologically tractable, account of rational commitment. Presentations of earlier drafts of the paper were given at a seminar at the Centre for Study of Mind and Nature, Oslo, as well as the conference of the European Society for Philosophy and Psychology.

I argue that coherence is truth-conducive in that coherence implies an increase in the probability of truth. Central to my argument is a certain principle for transitivity in probabilistic support. I then address a question concerning the truth-conduciveness of coherence as it relates to (something else I argue for) the truth-conduciveness of consistency, and consider how the truth-conduciveness of coherence bears on coherentist theories of justification.

Recently there have been several attempts in formal epistemology to develop an adequate probabilistic measure of coherence. There is much to recommend probabilistic measures of coherence. They are quantitative and render formally precise a notion—coherence—notorious for its elusiveness. Further, some of them do very well, intuitively, on a variety of test cases. Siebel, however, argues that there can be no adequate probabilistic measure of coherence. Take some set of propositions A, some probabilistic measure of coherence, and a probability distribution such (...) that all the probabilities on which A’s degree of coherence depends (according to the measure in question) are defined. Then, the argument goes, the degree to which A is coherent depends solely on the details of the distribution in question and not at all on the explanatory relations, if any, standing between the propositions in A. This is problematic, the argument continues, because, first, explanation matters for coherence, and, second, explanation cannot be adequately captured solely in terms of probability. We argue that Siebel’s argument falls short. (shrink)

In moral epistemology, the method of reflective equilibrium is often characterized in terms of intuitions or understood as a method for justifying intuitions. An analysis of reflective equilibrium and current theories of moral intuitions reveals that this picture is problematic. Reflective equilibrium cannot be adequately characterized in terms of intuitions. Although the method presupposes that we have initially credible commitments, it does not presuppose that they are intuitions. Nonetheless, intuitions can enter the process of developing a reflective equilibrium and, if (...) the process is successful, be justified. Since the method of reflective equilibrium does not essentially involve intuitions, it does not constitute a form of intuitionism in any substantial sense. It may be classified as intuitionist only in the minimal sense of not reducing justification to a matter of inference relations alone. (shrink)

The construction of a systematic philosophical foundation for logic is a notoriously difficult problem. In Part One I suggest that the problem is in large part methodological, having to do with the common philosophical conception of “providing a foundation”. I offer an alternative to the common methodology which combines a strong foundational requirement with the use of non-traditional, holistic tools to achieve this result. In Part Two I delineate an outline of a foundation for logic, employing the new methodology. The (...) outline is based on an investigation of why logic requires a veridical justification, i.e., a justification which involves the world and not just the mind, and what features or aspect of the world logic is grounded in. Logic, the investigation suggests, is grounded in the formal aspect of reality, and the outline proposes an account of this aspect, the way it both constrains and enables logic, logic's role in our overall system of knowledge, the relation between logic and mathematics, the normativity of logic, the characteristic traits of logic, and error and revision in logic.

This paper investigates the nature of scientific realism. I begin by considering the anomalous fact that Bas van Fraassen’s account of scientific realism is strikingly similar to Arthur Fine’s account of scientific non-realism. To resolve this puzzle, I demonstrate how the two theorists understand the nature of truth and its connection to ontology, and how that informs their conception of the realism debate. I then argue that the debate is much better captured by the theory of truthmaking, and not by (...) any particular theory of truth. To be a scientific realist is to adopt a realism-relevant account of what makes true the scientific theories one accepts. The truthmaking approach restores realism’s metaphysical core—distancing itself from linguistic conceptions of the debate—and thereby offers a better characterization of what is at stake in the question of scientific realism.

Could there be a cognitive zombie – that is, a creature with the capacity for cognition, but no capacity for consciousness? Searle argues that there cannot be a cognitive zombie because there cannot be an intentional zombie: on this view, there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and intentionality. However, I argue that there are good empirical reasons for rejecting the proposed connection between consciousness and intentionality. Instead, I argue (...) that there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and rationality. On this view, there cannot be a cognitive zombie because there cannot be a rational zombie. (shrink)

Some recent work in formal epistemology shows that “witness agreement” by itself implies neither an increase in the probability of truth nor a high probability of truth—the witnesses need to have some “individual credibility.” It can seem that, from this formal epistemological result, it follows that coherentist justification (i.e., doxastic coherence) is not truth-conducive. I argue that this does not follow. Central to my argument is the thesis that, though coherentists deny that there can be noninferential justification, coherentists do not (...) deny that there can be individual credibility. (shrink)

It is standard practice, when distinguishing between the foundationalist and the coherentist, to construe the coherentist as an internalist. The coherentist, the construal goes, says that justification is solely a matter of coherence, and that coherence, in turn, is solely a matter of internal relations between beliefs. The coherentist, so construed, is an internalist (in the sense I have in mind) in that the coherentist, so construed, says that whether a belief is justified hinges solely on what the subject is (...) like mentally. I argue that this practice is fundamentally misguided, by arguing that the foundationalism / coherentism debate and the internalism / externalism debate are about two very different things, so that there is nothing, qua coherentist, precluding the coherentist from siding with the externalist. I then argue that this spells trouble for two of the three most pressing and widely known objections to coherentism: the Alternative-Systems Objection and the Isolation Objection. (shrink)

It is common to hear talk of the aim of belief and to find philosophers appealing to that aim for numerous explanatory purposes. What belief 's aim explains depends, of course, on what that aim is. Many hold that it is somehow related to truth, but there are various ways in which one might specify belief 's aim using the notion of truth. In this article, by considering whether they can account for belief 's standard of correctness and the epistemic (...) norms governing belief, I argue against certain prominent specifications of belief 's aim given in terms of truth, and advance a neglected alternative.

Andrew Cling presents a new version of the epistemic regress problem, and argues that intuitionist foundationalism, social contextualism, holistic coherentism, and infinitism fail to solve it. Cling’s discussion is quite instructive, and deserving of careful consideration. But, I argue, Cling’s discussion is not in all respects decisive. I argue that Cling’s dilemma argument against holistic coherentism fails.

A direct realist theory of perceptual justification. I take a ground-up approach, beginning with a theory of subjective rationality understood in terms of first-person rational explicability of the stream of consciousness. I mathematize this picture via a Tractarian spin on a semantical framework developed by Rayo. Perceptual states justify by being 'receptive': rationally inexplicable intentional states encoded in sentences that are analytic. Direct realists working within this framework should say that when one is taken in by hallucination one's overall picture (...) of the world is incoherent; in this sense, a belief based on delusive hallucination can be provided with exculpation but not with justification.

Infallibilism is the claim that knowledge requires that one satisfies some infallibility condition. I spell out three distinct such conditions: epistemic, evidential and modal infallibility. Epistemic infallibility turns out to be simply a consequence of epistemic closure, and is not infallibilist in any relevant sense. Evidential infallibilism i s unwarranted but it is not an satisfactory characterization of the infallibilist intuition. Modal infallibility, by contrast, captures the core infallibilist intuition, and I argue that it is required to solve the Gettier (...) problem and account for lottery cases. Finally, I discuss whether modal infallibilism has sceptical consequences and argue that it is an open question whose answer depends on one’s account of alethic possibility. (shrink)

In this article I argue that the prevalence of intersubjective disagreement in epistemology poses a serious problem for Epistemic Externalism. I put the problem in the form of a dilemma: either Epistemic Externalism is not a complete account of epistemic justification or it's implausible to claim that the belief that Epistemic Externalism is true is itself an externalistically justified belief.

Suppose our visual experiences immediately justify some of our beliefs about the external world — that is, justify them in a way that does not rely on our having independent reason to hold any background belief. A key question now arises: Which of our beliefs about the external world can be immediately justified by experiences? I address this question in epistemology by doing some philosophy of mind. In particular, I evaluate the following proposal: if your experience e immediately justifies you (...) in believing that p , then (i) e has the content that p , and (ii) e ’s having the content that p is fixed by what it is like to have e . I start by clarifying this proposal and surveying the case in its favour. I then argue against the proposal and develop an alternative. The discussion shows what role visual consciousness plays and does not play in the justification of perceptual beliefs. (shrink)

The internalism /externalism debate is of interest in epistemology since it addresses one of the most fundamental questions in the discipline: what is the basic nature of knowledge and epistemic justification? It is generally held that if a positive epistemic status obtains, this is not a brute fact. Rather if a belief is, for example, justified, it is justified in virtue of some further condition obtaining. What has been called epistemic internalism holds, as the label suggests, is that all the (...) relevant factors that determine justification must be “internal”. Epistemic externalism is the denial of internalism. Epistemic internalism about justification is the subject of this article. After introducing the central intuitive considerations that have tended to motivate internalism, this paper will explore different ways of construing the internalist position. In addition to classical formulations, more recent formulations will be discussed, concluding with a discussion of an emerging position known as “Epistemological Disjunctivism”, which its advocates claim preserves the most important features of more traditional forms of internalism, while avoiding their difficulties. Epistemological Disjunctivism is particularly worthy of attention since if true, it promises to bridge internalist and externalist epistemologies, bringing a rapprochement to two sides of what may otherwise appear a deep and intractable debate about the fundamental nature of epistemology.

Coherentists on epistemic justification claim that all justification is inferential, and that beliefs, when justified, get their justification together (not in isolation) as members of a coherent belief system. Some recent work in formal epistemology shows that “individual credibility” is needed for “witness agreement” to increase the probability of truth and generate a high probability of truth. It can seem that, from this result in formal epistemology, it follows that coherentist justification is not truth-conducive, that it is not the case (...) that, under the requisite conditions, coherentist justification increases the probability of truth and generates a high probability of truth. I argue that this does not follow. (shrink)

Timothy Williamson's new book, The Philosophy of Philosophy, has a number of central themes. The very idea that philosophy has a method which is different in kind from the sciences is one Williamson rejects. “… the common assumption of philosophical exceptionalism is false. Even the distinction between the a priori and the a posteriori turns out to obscure underlying similarities”. Although Williamson sees the book as “a defense of armchair philosophy”, he also argues that “the differences in subject matter between (...) philosophy and the other sciences are also less deep than is often supposed. In particular, few philosophical questions are conceptual questions in any distinctive sense. …”. In addition, Williamson argues that “the current philosophical mainstream has failed to articulate an adequate philosophical methodology, in part because it has fallen into the classic epistemological error of psychologizing the data. … The picture is wrong; we frequently have better epistemic access to our immediate physical environment than to our own psychology. … Our understanding of philosophical methodology must be rid of internalist preconceptions”. I am tremendously sympathetic with all of these views.In this review, I want to raise a number of questions about philosophical methodology which Williamson does not address. While Williamson is wonderfully forthright on many important issues about philosophical methodology, the view he presents is compatible with a surprisingly wide range of approaches to philosophical questions. This may be precisely what Williamson wants. At this stage in our understanding of the philosophical enterprise, it may be premature to narrow the range of methodological options more than Williamson does. There are some hints, however, that Williamson may favor some of these options more than others, and, if that is so, it would be useful to make that clear and …. (shrink)

Tradition compels me to write dissertation acknowledgements that are long, effusive, and unprofessional. Fortunately for me, I heartily endorse that tradition.

How can you give your interlocutor a reason to act? One way is by manipulating his deliberative context through threats, flattery, or other incentives. Another is by addressing him in the way distinctive of reasoning with him. I aim to account for the possibility of this non-manipulative form of address by showing how it is realized through the performance of a specific illocutionary act, that of advising as inviting to trust. I argue that exercise of a capacity for reasonable trust (...) can give us reasons that are not grounded in our motivational susceptibilities. Here I echo Kant on moral motivation. But this rational faculty assesses not principles but persons. Here I echo Hume on the moral virtues. We can thus agree with Kant about the motivational efficacy of practical reasons dispensed through advice but agree with Hume about the form of intelligence needed to put ourselves in touch with them.
