Disagreement in Philosophy

In “Belief in the Face of Controversy,” Hilary Kornblith argues for a radical form of epistemic modesty: given that there has been no demonstrable cumulativeprogress in the history of philosophy – as there has been in formal logic, math, and science – Kornblith concludes that philosophers do not have the epistemic credibility to be trusted as authorities on the questions they attempt to answer. After reconstructing Kornblith's position, I will suggest that it requires us to adopt a different conception of (...) philosophy's epistemic value. First, I will argue that ‘progress’ has a different meaning in logic, science and philosophy, and that to judge one of these disciplines by the standards appropriate to one of the others obscures the unique epistemic functions of all. Second, I will argue that philosophy is epistemically unique in that it is a non-relativistic but historically determined excavation of foundations. Finally, drawing on Frank Herbert's Dune, I will suggest that Kornblith leaves us with a choice between two epistemic ideals: the hyper-logical ‘Mentat,’ or the historically informed ‘pre-born.’.

To address the underrepresentation of women in philosophy effectively, we must understand the causes of the early loss of women. In this paper we challenge one of the few explanations that has focused on why women might leave philosophy at early stages. Wesley Buckwalter and Stephen Stich offer some evidence that women have different intuitions than men about philosophical thought experiments. We present some concerns about their evidence and we discuss our own study, in which we attempted to replicate their (...) results for 23 different responses to 14 scenarios . We also conducted a literature search to see if other philosophers or psychologists have tested for gender differences in philosophical intuitions. Based on our findings, we argue that that it is unlikely that gender differences in intuitions play a significant role in driving women from philosophy. (shrink)

Epistemic trespassers judge matters outside their field of expertise. Trespassing is ubiquitous in this age of interdisciplinary research and recognizing this will require us to be more intellectually modest.

ABSTRACTMany philosophers have suggested that disagreement is good grounds for scepticism. One response says that disagreement-motivated scepticism can be mitigated to some extent by the thesis that philosophical disputes are often verbal, not genuine. I consider the implications of this anti-sceptical strategy, arguing that it trades one kind of scepticism for others. I conclude with suggestions for further investigation of the epistemic significance of the nature of philosophical disagreement.

ABSTRACT ABSTRACT: Most of what we believe comes to us from the word of others, but we do not always believe what we are told. We often reject thinkers’ reports by attributing biases to them. We may call this debunking. In this essay, I consider how debunking might work and then examine whether, and how often, it can help to preserve rational belief in the face of disagreement.

Should we believe our controversial philosophical views? Recently, several authors have argued from broadly conciliationist premises that we should not. If they are right, we philosophers face a dilemma: If we believe our views, we are irrational. If we do not, we are not sincere in holding them. This paper offers a way out, proposing an attitude we can rationally take toward our views that can support sincerity of the appropriate sort. We should arrive at our views via a certain (...) sort of ‘insulated’ reasoning – that is, reasoning that involves setting aside certain higher-order worries, such as those provided by disagreement – when we investigate philosophical questions.

In this paper, we will discuss Peter van Inwagen’s contribution to the epistemological debate about revealed peer disagreement. Roughly, this debate focuses on situations in which at least two participants disagree on a certain proposition based on the same evidence. This leads to the problem of how one should react rationally when peer disagreement is revealed. Van Inwagen, as we will show, discusses four possible reactions, all of which he rejects as unsatisfying. Our proposal will be to point to hidden (...) assumptions in van Inwagen’s reasoning and ask whether he is willing to reject at least one of these to get rid of the problem. In short, our thesis amounts to the following: Of the two epistemological claims, which we call “Weak” and “Full-blown Fallibilism”, van Inwagen cannot simultaneously accept the first and reject the latter, while this is what he seems to suggest. Revealing this potential dilemma for van Inwagen’s position will lead to a more detailed discussion of how “rationality”, “truth”, “evidence” and “justification” interrelate and how a closer look at their relation might help solving the puzzle of revealed peer disagreement.

What are the philosophical views of contemporary professional philosophers? We surveyed many professional philosophers in order to help determine their views on 30 central philosophical issues. This article documents the results. It also reveals correlations among philosophical views and between these views and factors such as age, gender, and nationality. A factor analysis suggests that an individual's views on these issues factor into a few underlying components that predict much of the variation in those views. The results of a metasurvey (...) also suggest that many of the results of the survey are surprising: philosophers as a whole have quite inaccurate beliefs about the distribution of philosophical views in the profession.

Suppose a person who is agnostic about most philosophical issues wishes to have true philosophical beliefs but equally wishes to avoid false philosophical beliefs. I argue that this truth-seeking, error-avoiding agnostic would not have good grounds for pursuing philosophy. Widespread disagreement shows that pursuing philosophy is not a reliable method of discovering true answers to philosophical questions. More likely than not, pursuing philosophy leads to false belief. Many attempts to rebut this sceptical argument fail.

This book appears as the eighth installment of the series Controversies, which is edited by Marcelo Dascal at Tel Aviv University. The series has as its stated goal publishing "studies in the theory of controversy, . . . studies in the history of controversy forms and their evolution, case studies of particular or current controversies, . . . and other controversy focused books". Senderowicz is a Kantian scholar, having also written The Coherence of Kant's Transcendental Idealism and several papers interpreting (...) Kant. Both of these themes are evident in Controversies and the Metaphysics of Mind. The book offers a decidedly neo-Kantian interpretation of the role that controversies play in metaphysical theorizing and applies this interpretation to two recent debates in the metaphysics of mind. The first is the debate about physicalism and the second is the debate about personal identity. The issues that are addressed include the relation of metaphysics to science and whether or not metaphysics deals with a distinctive subject matter or uses a distinctive method. This puts the book amongst the growing number of works in metametaphysics. (shrink)

Controversial view agnosticism (CVA) is the thesis that we are rationally obligated to withhold judgment about a large portion of our beliefs in controversial subject areas, such as philosophy, re- ligion, morality and politics. Given that one’s social identity is in no small part a function of one’s positive commitments in controversial areas, CVA has unsurprisingly been regarded as objection- ably ‘spineless.’ at said, CVA seems like an unavoidable consequence of a prominent view in the epistemology of disagreement—conformism—according to which (...) the rational response to discover- ing that someone you identify as an epistemic peer or expert about p disagrees with you vis-à-vis p is to withhold judgment. is paper proposes a novel way to maintain the core conciliatory in- sight without devolving into an agnosticism that is objectionably spineless. e approach offered takes as a starting point the observation that–for reasons that will be made clear—the contemporary debate has bypassed the issue of the reasonableness of maintaining, rather than giving up, represen- tational states weaker than belief in controversial areas. e new position developed and defended here explores this overlooked space; what results is a kind of controversial view agnosticism that is compatible with the kinds of commitments that are integral to social identity.

The philosophical interest of verbal disputes is twofold. First, they play a key role in philosophical method. Many philosophical disagreements are at least partly verbal, and almost every philosophical dispute has been diagnosed as verbal at some point. Here we can see the diagnosis of verbal disputes as a tool for philosophical progress. Second, they are interesting as a subject matter for first-order philosophy. Reflection on the existence and nature of verbal disputes can reveal something about the nature of concepts, (...) language, and meaning. In this article I first characterize verbal disputes, spell out a method for isolating and resolving them, and draw out conclusions for philosophical methodology. I then use the framework to draw out consequences in first-order philosophy. In particular, I argue that the analysis of verbal disputes can be used to support the existence of a distinctive sort of primitive concept and that it can be used to reconstruct a version of an analytic/synthetic distinction, where both are characterized in dialectical terms alone.

One of Mill’s main arguments for free speech springs from taking disagreement as an epistemically valuable resource for fallible thinkers. Contemporary conciliationist treatments of disagreement spring from the same motivation, but end up seeing the epistemic implications of disagreement quite differently. Conciliationism also encounters complexities when transposed from the 2-person toy examples featured in the literature to the public disagreements among groups that give the issue much of its urgency. Group disagreements turn out to be in some ways more powerful (...) defeaters of rational belief, even when opposing groups are comparable in size and epistemic credentials. And conciliationism also shows us why determining the rational response to these disagreements can in certain cases (e.g. politics) be a particularly difficult and nuanced matter. (shrink)

This special issue of Erkenntnis is devoted to the varieties of disagreement that arise in different areas of discourse, and the consequences we should draw from these disagreements, either concerning the subject matter and its objectivity, or concerning our own views about this subject matter if we learn, for example, that an epistemic peer disagrees with our view. In this introduction we sketch the background to the recent philosophical discussions of these questions, and the location occupied therein by the articles (...) in this collection. (shrink)

Set in the context of the current interest among Analytic philosophers in the “epistemology of disagreement,” this paper explores the meta-philosophical problem of philosophical incommensurability. Motivated by Nietzsche’s provocative remark about philosophy as prejudices and desires of the heart “sifted and made abstract,” the paper first outlines the contours of the problem and then traces it through a series of examples. Drawing largely on the tradition of phenomenology and philosophical hermeneutics, a broadly Continental response to this formidable problem is suggested. (...) Disagreement cannot be understood simply in terms of epistemological strategy, but needs to be regarded in a fundamentally hermeneutical light. (shrink)

In broad terms, realism, relativism and pluralism can be regarded as the theoretical articulations of the following insights. Realism embodies the sense that what is at stake in our beliefs is something serious, i.e. that there is a fact of the matter, independent from our desire, which is going to decide whether what we believe in is true or not. Relativism, on the other hand, incorporates the realization that our cognitive take on the world is always perspectival, that there is (...) no way to overcome the blind spot which enables the knower to have a world in view at all. Pluralism, finally, draws on the intuition that every human being and every human community cannot fully understand, let alone save themselves, without the help of others’ sense-making efforts. Against the background of Charles Taylor’s philosophy, the core of truth of the above insights will be discussed and arranged to develop an active view of toleration that not only urges us to put up with others, but encourages us to rely on the benefit of coming to terms with different outlooks and ways of life.

One can attack a philosophical claim by identifying a misuse of the language used to state it. I distinguish between two varieties of this strategy: one belonging to Norman Malcolm and the other to Ludwig Wittgenstein. The former is flawed and easily dismissible as misled linguistic conservatism. It muddies the name of ordinary language philosophy. I argue that the latter avoids this flaw. To make perspicuous the kind of criticism of philosophical claims that the second variety makes available, I draw (...) a comparison between Wittgenstein’s recommendation that philosophers study ordinary language and Alfred Schütz’s recommendation that social scientists study the methods of the agents they study. Both do so in an attempt to sensitise philosophers and social scientists respectively to particular artefacts of method which can be easily mistaken for features of that which is studied. (shrink)

Some moral disagreements are so persistent that we suspect they are deep : we would disagree even when we have all relevant information and no one makes any mistakes. The possibility of deep disagreement is thought to drive cognitivists toward relativism, but most cognitivists reject relativism. There is an alternative. According to divergentism, cognitivists can reject relativism while allowing for deep disagreement. This view has rarely been defended at length, but many philosophers have implicitly endorsed its elements. I will defend (...) it. (shrink)

What, if anything, is the correlation between the specialized or technical ideas of the philosopher and the rest of his existence? His everyday life outside his philosophical role. In the specialized reality and reality constitution, when employing the discourse and discipline of philosophy, the philosopher subscribe to many things in an explicit manner and he employs a number of implicit things and assumptions that are not stated explicitly. These things concern the different branches, areas and domains of the philosophical discourse, (...) for example metaphysics, epistemology, ethics, ontology, cognition, consciousness, mind, perception, thinking, etc. Is there a relation between these technical 'beliefs' of the philosopher and other, not philosophical areas of his existence? Does and can all of his non-philosophical existence reflect his philosophical beliefs, statements and expressions? Is it possible that the everyday existence or life world of the philosopher can resemble, confirm and express his philosophical ideas? If this is not the case, what are the factors that are involved in such discrepancies? Do they imply a lack of integrity, of wholeness of integration on behalf of the philosopher? What are the causes of such an illogical or surprising lack of compatibility or similarity between these sets of two or more facts? What are the things that we can look for in such a lack of compatibility – things such as the following? - inconsistency, difference, disparity, variance, variation, deviation, divergence, -/- disagreement, dissimilarity, dissimilitude, mismatch, lack of similarity, contrariety, contradictoriness, disaccord, discordance, incongruity, -/- lack of congruence, incompatibility, irreconcilability, conflict, opposition? -/- I illustrate the above by means of four examples. 1 Let us assume that the embodied human person consists of both voluntary and involuntary processes and activities. Do the philosophy of an individual reflect or express these activities or is it completely or partially unrelated to them? Do the voluntary processes and activities or the voluntary aspects of perception, cognition, brain processes and other activities resemble or express the philosophy of a thinker? 2 Some thinkers are seriously concerned about the importance of discourse and dialogue and the equality of all those involved. We find their concern about the ideal discourse and dialogue described in their written work and talks, but to what an extend do their own discursive and dialogical actions and behaviour reflect the ideal situation they preach? 3 Ethics and morality can be find in and are emphasized in all sorts of disciplines, of course they are major subjects in providing ways to live off for philosophers and we even find institutions devoted to their teaching and investigation. Do the lives, the lived morality and ethics of those individuals who preach the ideals of ethics or ethical ideals reflect the ideals they preach and that provides them with ways to earn a living? Or, is it the case that morality and ethics are merely faked by those individuals living off their preaching of ethics? And, that they merely employ the values, norms, customs and attitudes of a culture, sub-culture, community, group or another social grouping? In other words are the preachers of ethics really more ethical than the rest of the community and society? 4 When the philosopher expresses his ideas by means of all sorts of philosophical tools he is aware of the fact that he employs them, or at least aware of some of them being intentionally employed by him while he is unaware of others that he employs. Do the tools the philosopher employs to theorize (identify problems, the nature of the questions he asks, the nature of his ways of questioning, the assumptions he makes, the forming and testing of hypotheses, the making of generalizations, etc) or philosophize (perceive things, think, think about things, reason, argumentation etc) resemble what he beliefs, asserts and says about thinking, perception, cognition, understanding, subjects, objects, relationships between subjects and objects and other features and processes of epistemology? In short – does the lived philosophy, ontology, epistemology, ethics etc of the philosopher resemble, represent, confirm, substantiate, back, endorse, support, authenticate and corroborate the ideas, assertions and speculations that are expressed by the statements his philosophy or philosophizing consist of? Does he walk the walk of his talk? Are they similar and identical, the same things and merely expressions of the same things in different mediums? (shrink)

Except for a patina of twenty-first century modernity, in the form of logic and language, philosophy is exactly the same now as it ever was; it has made no progress whatsoever. We philosophers wrestle with the exact same problems the Pre-Socratics wrestled with. Even more outrageous than this claim, though, is the blatant denial of its obvious truth by many practicing philosophers. The No-Progress view is explored and argued for here. Its denial is diagnosed as a form of anosognosia, a (...) mental condition where the affected person denies there is any problem. The theories of two eminent philosophers supporting the No-Progress view are also examined. The final section offers an explanation for philosophy 's inability to solve any philosophical problem, ever. The paper closes with some reflections on philosophy 's future. (shrink)

This paper presents a new solution to the problem of peer disagreement that distinguishes two principles of rational belief, here called probability and autonomy. When we discover that we disagree with peers, there is one sense in which we rationally ought to suspend belief, and another in which we rationally ought to retain our original belief. In the first sense, we aim to believe what is most probably true according to our total evidence, including testimony from peers and authorities. In (...) the second, we aim to base our beliefs only on objective evidence and argumentation, even if that lowers the probability of their being true. The first principle of rational belief tends to serve the short-term epistemic interests of individuals, while the second tends to serve the long-term epistemic interests of both individuals and groups. The best way to reconcile these principles in cases of peer disagreement is to associate them with two corresponding species of belief, here called perception and opinion. (shrink)

We review evidence showing that disagreement in folk and expert philosophical intuitions can be predicted by global, heritable personality traits. The review focuses on recent studies of intuitions about free will, ethics, and intentional action. These findings are philosophically important because they suggest that while some projects cannot be done, other projects must take individual differences in philosophical character into account. But care needs to be taken when interpreting the implications of these individual differences. We illustrate one way that these (...) differences have been abused. We then illustrate two ways that these findings can be legitimately used to help illuminate philosophical issues. Given the large and readily available body of evidence, neglect of persistent and predictable philosophical differences is irresponsible. (shrink)

One way to discredit the suggestion that a statement is true just in virtue of its meaning is to observe that its truth is the subject of genuine disagreement. By appealing to the case of the unorthodox philosopher, Timothy Williamson has recast this response as an argument foreclosing any appeal to analyticity. Reconciling Quine’s epistemological holism with his treatment of the ‘deviant logician’, I show that we may discharge the demands of charitable interpretation even while attributing trivial semantic error to (...) Williamson’s philosophers. Williamson’s effort to generalize the argument from disagreement therefore fails. (shrink)

It is valuable for inquiry to have researchers who are committed advocates of their own theories. However, in light of pervasive disagreement, such a commitment is not well explained by the idea that researchers believe their theories. Instead, this commitment, the rational attitude to take toward one’s favored theory during the course of inquiry, is what I call endorsement. Endorsement is a doxastic attitude, but one which is governed by a different type of epistemic rationality. This inclusive epistemic rationality is (...) sensitive to reasons beyond those to think the particular proposition in question is true. Instead, it includes extrinsic epistemic reasons, which concern the health of inquiry more generally. Such extrinsic reasons include the distribution of cognitive labor that a researcher will contribute to by endorsing a particular theory. Recognizing endorsement and inclusive epistemic rationality thus allows us to smooth a tension between individual rationality and collective rationality. It does so by showing how it can be epistemically rational to endorse a theory on the basis of the way this endorsement will benefit collective inquiry. I provide a decision theoretic treatment for inclusive epistemic rationality and endorsement which illustrates how this can be accomplished. (shrink)

By considering the epistemology and relations among certain philosophical problems, I argue for a disjunctive thesis: either (1) it is highly probable that there are (i) several (ii) mutually independent philosophical reductios of highly commonsensical propositions that are successful—so several aspects of philosophy have succeeded at refuting common sense—or (2) there is enough hidden semantic structure in even simple sentences of natural language to make philosophers highly unreliable at spotting deductive validity in some of the simplest cases—so we are much (...) worse at logic than we think and cannot, in general, know when our own arguments are valid. The untoward consequences of each disjunct are explained. (shrink)

Philosophical expertise consists in knowledge, but it is controversial what this knowledge consists in. I focus on three issues: the extent and nature of knowledge of philosophical truths, how this philosophical knowledge is related to philosophical progress, and skeptical challenges to philosophical knowledge.

There is a long history of using facts about disagreement to argue that many of our most precious beliefs are false in a way that can make a difference in our lives. In this essay I go over a series of such arguments, arguing that the best arguments target beliefs that meet two conditions: (i) they have been investigated and debated for a very long time by a great many very smart people who are your epistemic superiors on the matter (...) and have worked very hard under optimal circumstances to figure out if the belief is true, and (ii) as far as you know these people have not come to any significant agreement on the belief and as far as you know those who agree with you are not, as a group, in a better position to judge the belief than those who disagree with you. (shrink)

I first argue that there is plenty of agreement among philosophers on philosophically substantive claims, which fall into three categories. This agreement suggests that there is important philosophical progress. I then argue that although it’s easy to list several potential kinds of philosophical progress, it is much harder to determine whether the potential is actual. Then I attempt to articulate the truth that the deniers of philosophical progress are latching on to. Finally, I comment on the significance of the agreement (...) and (potential) progress. (shrink)

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

In this essay I try to motivate and formulate the main epistemological questions to ask about the phenomenon of religious disagreement. I will not spend much time going over proposed answers to those questions. I address the relevance of the recent literature on the epistemology of disagreement. I start with some fiction and then, hopefully, proceed with something that has at least a passing acquaintance with truth.

If you retain your belief upon learning that a large number and percentage of your recognized epistemic superiors disagree with you, then what happens to the epistemic status of your belief? I investigate that theoretical question as well has the applied case of philosophical disagreement—especially disagreement regarding purely philosophical error theories, theories that do not have much empirical support and that reject large swaths of our most commonsensical beliefs. I argue that even if all those error theories are false, either (...) (a) the average philosopher’s true commonsensical beliefs are epistemically impoverished, or (b) a good portion of philosophy is bunk and philosophers should give up most of their error theories despite the fact that their supporting arguments are generally as good as or even better than other philosophical arguments. (shrink)

Philosophers often find themselves in disagreement with contemporary philosophers they know full well to be their epistemic superiors on the topics relevant to the disagreement. This looks epistemically irresponsible. I offer a detailed investigation of this problem of the reflective epistemic renegade. I argue that although in some cases the renegade is not epistemically blameworthy, and the renegade situation is significantly less common than most would think, in a troublesome number of cases in which the situation arises the renegade is (...) blameworthy in her disagreement with recognized epistemic superiors. I also offer some thoughts on what it would mean for philosophical practice for us to refrain from being renegades. Finally, I show how a new kind of radical skepticism emerges from modest theses regarding the renegade. (shrink)

This is a short essay that presents what I take to be the main questions regarding the epistemology of disagreement.

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

I’m going to argue for a set of restricted skeptical results: roughly put, we don’t know that fire engines are red, we don’t know that we sometimes have pains in our lower backs, we don’t know that John Rawls was kind, and we don’t even know that we believe any of those truths. However, people unfamiliar with philosophy and cognitive science do know all those things. The skeptical argument is traditional in form: here’s a skeptical hypothesis; you can’t epistemically neutralize (...) it, you have to be able to neutralize it to know P; so you don’t know P. But the skeptical hypotheses I plug into it are “real, live” scientific-philosophical hypotheses often thought to be actually true, unlike any of the outrageous traditional skeptical hypotheses (e.g., ‘You’re a brain in a vat’). So I call the resulting skepticism Live Skepticism. Notably, the Live Skeptic’s argument goes through even if we adopt the clever anti-skeptical fixes thought up in recent years such as reliabilism, relevant alternatives theory, contextualism, and the rejection of epistemic closure. Furthermore, the scope of Live Skepticism is bizarre: although we don’t know the simple facts noted above, many of us do know that there are black holes and other amazing facts. (shrink)

Peter Unger has challenged philosophical objectivism, the thesis that traditional philosophical problems have definite objective answers. He argues from semantic relativity for philosophical relativity, the thesis that for certain philosophical problems, there is no objective answer. I clarify, formulate and challenge Unger's argument. According to Unger, philosophical relativism explains philosophical idling, the fact that philosophical debates appear endless, philosophical disagreements seem irresolvable, and very little substantial progress seems made towards satisfactory and definite answers to philosophical problems. I argue, however, that (...) the reality of philosophical idling is doubtful and, ironically, undermined by philosophical relativism. I then raise problems for several steps in Unger's argument for philosophical relativity. I conclude by arguing that philosophical relativism can avoid self-defeat only by an ad hoc limitation of its scope. (shrink)

I believe that the sort of disagreements we encounter in philosophy—disagreements that often take the form that I have elsewhere called system- atic peer disagreements—make it unreasonable to think that there is any knowledge, or even justified belief, when the disagreements themselves are systematic. I readily acknowledge that this skeptical view is quite controversial; I suspect many are unconvinced. However, I will not be defending it here. Rather, I will be exploring a worry, or set of worries, that arise on (...) the assumption that this view is correct. For if it is unreasonable to think that there is justified belief in contexts of systematic philosophical disagreements, by what right do we continue to advance philosophical claims in such contexts? Indeed, by what right do we believe the philosophical claims we advance? And if we don’t believe them, why do we advance them in the first place? An inability to respond to these worries would leave us with the dis- tinct impression that the practice or activity of philosophy is quite suspect: what sort of practice or activity would have us believe unreasonably, assert unwarrantedly, and perhaps exhibit insincerity to boot? (shrink)

The following three propositions appear to be individually defensible but jointly inconsistent: (1) reliability is a necessary condition on epistemic justification; (2) on contested matters in philosophy, my beliefs are not reliably formed; (3) some of these beliefs are epistemically justified. I explore the nature and scope of the problem, examine and reject some candidate solutions, compare the issue with ones arising in discussions about disagreement, and offer a brief assessment of our predicament.

In the history of philosophical thought, few themes loom as large as skepticism. Skepticism has been the most visible and important part of debates about knowledge. Skepticism at its most basic questions our cognitive achievements, challenges our ability to obtain reliable knowledge; casting doubt on our attempts to seek and understand the truth about everything from ethics, to other minds, religious belief, and even the underlying structure of matter and reality. Since Descartes, the defense of knowledge against skepticism has been (...) one of the primary tasks not just of epistemology but philosophy itself. The Oxford Handbook of Skepticism features twenty-six newly commissioned chapters by top figures in the field. Part One contains articles explaining important kinds of skeptical reasoning. Part Two focuses on responses to skeptical arguments. Part Three concentrates on important contemporary issues revolving around skepticism. As the first volume of its kind, the articles make significant contributions to the debate on skepticism. (shrink)

Conceptual Engineering alleges that philosophical problems are best treated via revising or replacing our concepts (or words). The goal here is not to defend Conceptual Engineering but rather show that it can (and should) invoke Neutralism—the broad view that philosophical progress can take place when (and sometimes only when) a thoroughly neutral, non-specific theory, treatment, or methodology is adopted. A neutralist treatment of one form of skepticism is used as a case study and is compared with various non-neutral rivals. Along (...) the way, a new taxonomy for paradox is proposed. (shrink)

In philosophy, as in many other disciplines and domains, stable disagreement among peers is a widespread and well-known phenomenon. Our intuitions about paradigm cases, e.g. Christensen's Restaurant Case, suggest that in such controversies suspension of judgment is rationally required. This would prima facie suggest a robust suspension of judgment in philosophy. But we are still lacking a deeper theoretical explanation of why and under what conditions suspension is rationally mandatory. In the first part of this paper I will focus on (...) this question. After a critical survey of some recent alternative approaches (diversity as a thread to the reliability, decision problem, acquisition of undercutting defeaters), I will argue that in fact discovering disagreement with an opponent provides me with a rebutting defeater, but only if some further non-trivial conditions are satisfied - among them my acknowledging her as my reliability peer. In the second part of the paper I will explore in more detail the skeptical implications this account has for philosophy. Here, I will defend two claims. First, skepticism about philosophy is mandatory only if the relevant peerness assumption can be justified. Second, in philosophy there is no basis available that would support the relevant peerness assumption. If this is correct, we are not forced into skepticism about philosophy and may rationally retain our philosophical beliefs even in the face of controversy. (shrink)
