Disagreement in Philosophy

The normative and metanormative pluralism that figures among core self-descriptions of democratic theory, which seems incompatible with democratic theorists’ practical ambitions, may stem from the internal logic of research traditions in the social sciences and humanities and in the conceptual structure of political theory itself. One way to deal productively with intradisciplinary diversity is to appeal to the idea of a meta-consensus; another is to appeal to the argument from cognitive diversity that fuels recent debates on epistemic democracy. For different (...) reasons, both strategies fail, such that a metatheoretical step aside may be desirable, one that entails modeling democratic theory after the public justification approach.

This paper explores the application of hinge epistemology to deep disagreement. Hinge epistemology holds that there is a class of commitments—hinge commitments—which play a fundamental role in the structure of belief and rational evaluation: they are the most basic general ‘presuppositions’ of our world views which make it possible for us to evaluate certain beliefs or doubts as rational. Deep disagreements seem to crucially involve disagreements over such fundamental commitments. In this paper, I consider pessimism about deep disagreement, the thesis (...) that such disagreements are rationally irresolvable, and ask whether the Wittgensteinian account of deep disagreement—according to which such disagreements are disagreements over hinge commitments—provides adequate support for pessimism. I argue that the answer to this question depends on what hinge commitments are and what our epistemic relation to them is supposed to be. I argue for two core claims. First, that non-epistemic theories of hinge commitments provide adequate support for pessimism. Nevertheless, such theories have highly implausible consequences in the context of deep disagreement. Secondly, at least one epistemic theory of hinge commitments, the entitlement theory, permits optimism about such disagreements. As such, while hinge epistemology is mainly pessimistic about deep disagreement, it doesn’t have to be. (shrink)

While it seems hard to deny the epistemic significance of a disagreement with our acknowledged epistemic peers, there are certain disagreements, such as philosophical disagreements, which appear to be permissibly sustainable. These two claims, each independently plausible, are jointly puzzling. This paper argues for a solution to this puzzle. The main tenets of the solution are two. First, the peers ought to engage into a deliberative activity of discovering more about their epistemic position vis-à-vis the issue at stake. Secondly, the (...) peers are permitted to do so while entertaining a sui generis doxastic attitude of hypothesis. (shrink)

Helen Beebee (2018) defends a view of the aims of philosophy she calls ‘equilibrism’. Equilibrism denies that philosophy aims at knowledge and maintains that the collective aim of philosophy is ‘to find what equilibria there are that can withstand examination’ (Beebee 2018, p. 3). In this note, I probe equilibrism by focusing on how disagreement challenges our doxastic commitment to our own philosophical theories. Call this the Commitment Challenge. I argue that the Commitment Challenge comes in three varieties and that (...) endorsing equilibrism provides us with an answer to one of them only. (shrink)

In this paper, I develop and respond to a novel objection to Conciliatory Views of disagreement. Having first explained Conciliationism and the problem of divine hiddenness, I develop an objection that Conciliationism exacerbates the problem of divine hiddenness. According to this objection, Conciliationism increases God’s hiddenness in both its scope and severity, and is thus incompatible with God’s existence (or at least make God’s existence quite improbable). I respond to this objection by showing that the problem of divine hiddenness is (...) not made any worse by Conciliationism. (shrink)

Standardly, epistemic peers regarding a given matter are said to be people of equal competence who share all relevant evidence. Alternatively, one can define epistemic peers regarding a given matter as people who are equally likely to be right about that matter. I argue that a definition in terms of likelihood captures the essence of epistemic peerhood better than the standard definition or any variant of it. What is more, a likelihood definition implies the truth of the central thesis in (...) the debate on peer disagreement, the so-called Equal Weight View, according to which we should give the opinions of our peers the same weight we give our own. Adopting a likelihood definition, however, does not end the debate on peer disagreement, because the alleged theoretical alternatives to the Equal Weight View, reinterpreted in the light of a likelihood definition, can in fact be shown to be compatible with this view—though the reinterpreted versions may appear less plausible than the original ones. (shrink)

A commonly neglected feature of the so-called Equal Weight View, according to which we should give our peers’ opinions the same weight we give our own, is its prima facie incompatibility with the common picture of philosophy as an armchair activity: an intellectual effort to seek a priori knowledge. This view seems to imply that our beliefs are more likely to be true if we leave our armchair in order to find out whether there actually are peers who, by disagreeing (...) with us, force us to revise our beliefs. This article argues that the Equal Weight View should be spelled out in such a way that not only actual peer disagreement requires us to revise our beliefs, but also merely possible peer disagreement. This result is not a reductio ad absurdum of the view. Quite the opposite: it shows that the view is, contrary to appearance, compatible with our common way of doing philosophy. (shrink)

There is no consensus about appropriate philosophical method that can be relied on to settle philosophical questions and instead of established findings, there are multiple conflicting arguments and positions, and widespread disagreement and debate. Given this feature of philosophy, it might seem that philosophy has proven to be a worthless endeavour, with no possibility of philosophical progress. The challenge then is to develop a conception of philosophy that reconciles the lack of general or lasting agreement with the possibility of philosophical (...) progress. I present such a conception in this paper. I argue that the aim of philosophy is to resolve philosophical problems, which is different from establishing settled and final answers or positions. Philosophical problems involve inadequate or incongruous conceptions that cannot be settled once and for all but can be resolved by transforming our conceptions so they are now congruous and adequate. There is philosophical progress every time a warranted, defensible position is developed that resolves a philosophical problem, even if there are competing resolutions and further problems to resolve, as there always are in philosophy.

Discovering someone disagrees with you is a common occurrence. The question of epistemic significance of disagreement concerns how discovering that another disagrees with you affects the rationality of your beliefs on that topic. This book examines the answers that have been proposed to this question, and presents and defends its own answer.

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.

In his recent work, Duncan Pritchard defends a novel Wittgensteinian response to the problem of radical scepticism. The response makes essential use of a form of non-epistemicism about the nature of hinge commitments. According to non-epistemicism, hinge commitments cannot be known or grounded in rational considerations, such as reasons and evidence. On Pritchard’s version of non-epistemicism, hinge commitments express propositions but cannot be believed. This is the non-belief theory of hinge commitments. One of the main reasons in favour of NBT (...) over rival anti-sceptical Wittgensteinian views is that it has less theoretical costs and revisionary consequences than its rivals. In this paper, I argue that NBT fares at least as bad as its rivals in terms of its theoretical costs and revisionism. In particular, I argue that NBT is inconsistent with certain cases of philosophical disagreement; that it faces worries with mental-state scepticism; and that it faces difficulties in explaining how we can represent ourselves as committed to hinge commitments.

This article is about the implications of a conciliatory view about the epistemology of peer disagreement for our moral beliefs. Many have endorsed a conciliatory view about the epistemology of peer disagreement according to which if we find ourselves in a disagreement about some matter with another whom we should judge to be our epistemic peer on that matter, we must revise our judgment about that matter. This article focuses on three issues about the implications of conciliationism for our moral (...) beliefs. The first is whether there is an asymmetry between the implications of conciliationism for the epistemic status of our moral beliefs and the implications of conciliationism for the epistemic status of our non-moral beliefs; for instance, some have argued that conciliationism leads to epistemological moral skepticism but not to epistemological nonmoral skepticism. The second is what the implications of conciliationism are for the epistemic status of particular moral beliefs. The third is whether conciliationism's impact on the epistemic status of our moral beliefs has practical implications. (shrink)

This essay addresses arguments regarding the “place” or “non-place” in which ideas originate and whether they are wholly transcendental, wholly contingent, or a combination of transcendental and contingent. Far from a resuscitation or recitation of Medieval scholastic disputations, the essay seeks to situate these untimely concerns in the context of spent discursive and ideological systems that support capitalist exploitation of the knowledge commons, exploitation only made possible because of a decisive and historically determined reduction of knowledge to fully contingent status (...) as spectral commodity.

This article examines the central epistemological issues tied to the recognition of disagreement.

The Uniqueness Thesis, or rational uniqueness, claims that a body of evidence severely constrains one’s doxastic options. In particular, it claims that for any body of evidence E and proposition P, E justifies at most one doxastic attitude toward P. In this paper I defend this formulation of the uniqueness thesis and examine the case for its truth. I begin by clarifying my formulation of the Uniqueness Thesis and examining its close relationship to evidentialism. I proceed to give some motivation (...) for this strong epistemic claim and to defend it from several recent objections in the literature. In particular I look at objections to the Uniqueness Thesis coming from considerations of rational disagreement (can’t reasonable people disagree?), the breadth of doxastic attitudes(can’t what is justified by the evidence encompass more than one doxastic attitude?), borderline cases and caution (can’t it be rational to be cautious and suspend judgment even when the evidence slightly supports belief?), vagueness (doesn’t the vagueness of justification spell trouble for the Uniqueness Thesis?), and degrees of belief (doesn’t a finegrained doxastic picture present additional problems for the Uniqueness Thesis?).

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.

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)

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)

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.

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)

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?

In “Are Certain Knowledge Frameworks More Congenial to the Aims of Cross-Cultural Philosophy? A Qualified Yes,” Leigh Jenco responds to an article in which I had argued for a similar conclusion. I had contended roughly that the positing of objective truth combined with a fallibilist epistemology best explains why a philosopher from one culture could learn something substantial from another culture. In her response, Jenco contends that this knowledge framework does not account adequately for the intuition that various philosophical traditions (...) have an equal standing and that traditions other than one’s own are not to be considered inferior. In addition, according to Jenco, an appeal to objective truth on the part of one epistemic culture is unavoidably oppressive, or overly risks being so, with regard to another one. In this brief reply, I argue that an appeal to objective truth in the realms of epistemology and morality in fact makes the most sense of Jenco’s concerns about inegalitarianism and oppression.

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.

This essay presents a dialogical framework for treating philosophical disagreements as persuasion dialogues with analogical argumentation, with the aim of recasting philosophical disputes as disagreements over analogies. This has two benefits: it allows us to temporarily bypass conflicting metaphysical intuitions by focusing on paradigmatic examples, similarities, and the plausibility of conclusions for or against a given point of view; and it can reveal new avenues of argumentation regarding a given issue. This approach to philosophical disagreements is illustrated by studying the (...) role of argumentation by analogy in disputes over Lockean justifications of intellectual property rights, and disagreements over whether artificial agents should be treated as moral agents. Finally, a nonexhaustive list of possible global and local points of contention over analogical arguments is identified in order to highlight potential avenues of argumentation in disagreements over analogies.

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)

Contributors to the recent disagreement debate have sought to provide a uniform response to cases in which epistemic peers disagree about the epistemic import of a shared body of evidence, no matter what kind of evidence they are disagreeing about. The varied cases addressed in the literature have included examples of disagreement about restaurant bills, court verdicts, weather forecasting, chess, morality, religious beliefs, and even disagreements about philosophical disagreements. The equal treatment of these varied cases has motivated the search for (...) a uniform response to peer disagreement wherever it is encountered. In this article I challenge this prevalent approach in the literature. I grant the notion of epistemic peer and accept that being a peer may amount to the same thing in different domains; nonetheless I contend that different domains appear to call for different responses to disagreement. I argue that the appropriate response to finding out about a disagreement with a peer is different in different domains. (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)

Widespread and lasting consensus has not been philosophy's fate. Indeed, one of philosophy's most striking features is its ability to accommodate “not only different answers to philosophical questions” but also “total disagreement on what questions are philosophical” (Rorty 1995, 58). It is therefore hardly surprising that philosophers' responses to this metaphilosophical predicament have been similarly varied. This article considers two recent diagnoses of philosophical diversity: Kornblith and Rescher (respectively) claim that taking philosophical disagreement seriously does not lead to metaphilosophical scepticism. (...) The article argues that their confidence is misplaced in so far as both wrongly assume that ordinary, first-order philosophical practice and second-order metaphilosophical reflection are separate enterprises. We can say that the universe consists of a substance, and this substance we will call “atoms,” or else we will call it “monads.” Democritus called it atoms. Leibniz called it monads. Fortunately, the two men never met, or there would have been a very dull argument. (Allen 1997, 171) When will philosophers learn to be less pretentious and arrogant in their claims? One would imagine that the philosophic experiences of twenty-five centuries would have taught them the fallacy of self-esteem! (Schilpp 1935, 233). (shrink)

Available from UMI in association with The British Library. ;The study centres around types of disagreement between philosophical systems, methods and theories. The underlying assumption being that disagreement over questions and puzzles, and the attempts at their resolution, have been one of the causes of the development of philosophical techniques of analysis and description thereby of our knowledge of the world and language. ;The discussion of disagreement in science marks the starting point in the present study so as to stave (...) off such a limiting case. The description of scientific disciplines as closed units, where description and explanation are only feasible if one subscribed to the thesis or assumption of the discipline, presents a borderline case. Contrary to science, various philosophical systems and methods of analysis and description, and their differences reflect many varied characters of philosophical disagreements both at the descriptive and methodological levels. The systems of philosophy, whether descriptive or revisionary, and, so too, the methods of philosophical analysis, description and argumentation are advocated or propounded with certain assumptions about the nature of reality and language. The question of the choice of system, method and theory is not so much important as the question, whether the system, method or theory so advanced follows the logical criteria of consistency and non-contradiction. The various instances discussed herein, are found, in one way or another, to be deficient when so examined. The claims to consistency and non-contradiction are not made to produce holistic accounts but for consistent descriptions of the world and language. To this end, certain types of disagreements found in philosophy are discussed. Even though the differing and disagreeing systems and methods are not always open to solutions yet they have contributed to philosophy. Every system or method has, in one way or another, attempted to make our thoughts clearer and opened up new vistas of philosophical endeavour. (shrink)

The disagreement of philosophers is notorious. In this book, Rescher develops a theory that accounts for this conflict and shows how the basis for philosophical disagreement roots in divergent 'cognitive values'-values regarding matters such as importance, centrality, and priority. In light of this analysis, Rescher maintains that, despite this inevitable discord, a skeptical or indifferentist reaction to traditional philosophy is not warranted, seeing that genuine value-conflicts are at issue. He argues that philosophy is an important and worthwhile enterprise, notwithstanding its (...) inability to achieve rationally constrained consensus on the issues. Given the nature of the enterprise, consensus is not a realistic goal, and failure to achieve it is not a defect. Accordingly, Rescher argues against the revisionist views proposed by Richard Rorty and Robert Nozick. His discussions are devoted to providing a clear view of why philosophical problems arise and how philosophers address them. (shrink)

Many philosophical disputes, most prominently disputes in ontology, have been suspected of being merely verbal and hence pointless. My goal in this paper is to offer an account of merely verbal disputes and to address the question of what is problematic with such disputes. I begin by arguing that extant accounts that focus on the semantics of the disputed statement S do not capture the full range of cases as they might arise in philosophy. Moreover, these accounts bring in heavy (...) theoretical machinery. I attempt to show that we can capture the full range of cases with an approach that is theoretically lightweight. This approach explains verbal disputes as a pragmatic phenomenon where parties use the same utterance type S with different speaker’s meaning. Moreover, it provides an answer to the crucial question Jackson’s pragmatic account leaves, at best, highly implicit. Based on my account, we can distinguish between different ways in which disputes can be verbal and different extents to which they are defective. Distinguishing between these varieties of verbalness furthermore allows us to specify what kind of substantive issues remain to be discussed once the linguistic confusion is resolved. (shrink)

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)

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)

My topic is two-fold: a reductive account of expertise as an epistemic phenomenon, and applying the reductive account to the question of whether or not philosophers enjoy expertise. I conclude, on the basis of the reductive account, that even though philosophers enjoy something akin to second-order expertise (i.e. they are often experts on the positions of other philosophers, current trends in the philosophical literature, the history of philosophy, conceptual analysis and so on), they nevertheless lack first-order philosophical expertise (i.e. expertise (...) on philosophical positions themselves such as the nature of mind, causality, normativity and so forth). Throughout the paper, I respond to potential objections. (shrink)

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.

We often find that beliefs we hold are in conflict with the beliefs of epistemic peers, individuals who are just as intelligent, just as well-informed, and just as scrupulous in forming their beliefs as we are. Is it permissible to maintain our beliefs in the face of such disagreement? It is argued here that continued belief in these circumstances is not epistemically permissible, and that this has striking consequences for the practice of philosophy: we cannot reasonably hold on to our (...) philosophical views.

Two main claims are defended in this paper: first, that typical disputes in the literature about the ontology of physical objects are merely verbal; second, that the proper way to resolve these disputes is by appealing to common sense or ordinary language. A verbal dispute is characterized not in terms of private idiolects, but in terms of different linguistic communities representing different positions. If we imagine a community that makes Chisholm's mereological essentialist assertions, and another community that makes Lewis's four-dimensionalist (...) assertions, the members of each community speak the truth in their respective languages. This follows from an application of the principle of interpretive charity to the two communities. (shrink)

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 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.

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)
