Disagreement

Modest pessimism about philosophical progress is the view that while philosophy may sometimes make some progress, philosophy has made, and can be expected to make, only very little progress (where the extent of philosophical progress is typically judged against progress in the hard sciences). The paper argues against recent attempts to defend this view on the basis of the pervasiveness of disagreement within philosophy. The argument from disagreement for modest pessimism assumes a teleological conception of progress, according to which the (...) attainment of true answers to the big philosophical questions, or knowledge of them, is the primary goal of philosophy. The paper argues that this assumption involves a misconception of the goal of philosophy: if philosophy has a primary goal, its goal is the understanding of philosophical problems rather than knowledge of answers to philosophical questions. Moreover, it is argued that if the primary goal of philosophy is such understanding, then widespread disagreement within philosophy does not indicate that philosophy makes little progress. (shrink)

Scientific disagreements are an important catalyst for scientific progress. But what happens when scientists disagree amidst times of crisis, when we need quick yet reliable policy guidance? In this paper we aim to provide a normative account for how scientists facing disagreement in the context of ‘fast science’ should respond, and how policy makers should evaluate such disagreement. Starting from an argumentative, pragma-dialectic account of scientific controversies (Donato Rodríguez and Zamora Bonilla, 2013), we argue for the importance of ‘higher-order evidence (...) (HOE)’, which has received insufficient attention in previous discussions on scientific disagreements and controversies, especially with regard to fast science. Moreover, we specify desiderata for scientifically relevant HOE. We use our account to analyze a recent disagreement on the aerosol transmission of the COVID19 virus and evaluate the standpoints of the parties involved in the dispute. (shrink)

This chapter considers the challenges to, and the resources for, cultivating a personal capacity for tolerance, given a Spinozist account of belief-formation. After articulating two main components of personal tolerance, I examine the features of Spinoza’s theory of cognition that make the cultivation of tolerance so difficult. This is followed by an analysis of Spinoza’s account of overcoming intolerant tendencies. Ultimately, I argue that the capacity of individuals to be tolerant depends crucially on the establishment of conditions of trust, conditions (...) that are conspicuously lacking in many modern democracies.

Political epistemology is the intersection of political philosophy and epistemology. This paper develops a political 'hinge' epistemology. Political hinge epistemology draws on the idea that all belief systems have fundamental presuppositions which play a role in the determination of reasons for belief and other attitudes. It uses this core idea to understand and tackle political epistemological challenges, like political disagreement, polarization, political testimony, political belief, ideology, and biases, among other possibilities. I respond to two challenges facing the development of a (...) political hinge epistemology. The first is about nature and demarcation of political hinges, while the second is about rational deliberation over political hinges. I then use political hinge epistemology to analyze ideology, dealing with the challenge of how an agent's ideology 'masks' or distorts their understanding of social reality, along with the challenge of how ideology critique can change the beliefs of agents who adhere to dominant ideologies, if agents only have their own or the competing ideology to rely on (see Haslanger 2017). I then explore how political hinge epistemology might be extended to further our understanding of political belief polarization. (shrink)

In contemporary political discussions, it is depressingly common to see people criticized for expressing impure beliefs. Moreover, those who sometimes defect from their tribe are criticized for failing to be firmly enough on the side of the angels. We consider explanations for this behavior, including its relationship to moral grandstanding. We will also argue, on both moral and epistemic grounds, in favor of a norm against “blocking the exits.” We should not use social pressure to discourage people from publicly changing (...) their minds.

Epistemic agents interact with evidence in different ways. This can cause trouble for mutual understanding and for our ability to rationally engage with others. Indeed, it can compromise democratic practices of deliberation. This paper explains these differences by appeal to a new notion: epistemic styles. Epistemic styles are ways of interacting with evidence that express unified sets of epistemic values, preferences, goals, and interests. The paper introduces the notion of epistemic styles and develops a systematic account of their nature. It (...) then discusses the implications of epistemic styles for central questions in epistemology, in particular, for issues surrounding rational engagement and for the debate between virtue epistemologists and epistemic situationists.

There is a correlation between positions taken on some scientific questions and political leaning. One way to explain this correlation is the Cultural Cognition Hypothesis (CCH): people’s political leanings are causing them to process evidence to maintain fixed answers to the questions, rather than to seek the truth. Another way is the Different Background Belief Hypothesis (DBBH): people of different political leanings have different background beliefs which rationalize different positions on these scientific questions. In this paper I argue for two (...) things. I argue that two attempts by proponents of the CCH to discredit the DBBH fail. And I argue that this matters, because while the CCH makes epistemic paternalistic interventions seem necessary (as some philosophers have argued compellingly), the DBBH does not. The DBBH makes it much easier to stay closer to an ideal of deliberative democracy. (shrink)

It is not uncommon in the history of science and philosophy to encounter crucial experiments or crucial objections the truth-value of which we are ignorant, that is, about which we suspend judgment. Should we ignore such objections? Contrary to widespread practice, I show that in and only in some circumstances they should not be ignored, for the epistemically rational doxastic attitude is to suspend judgment also about the hypothesis that the objection targets. In other words, suspension of judgment "propagates" from (...) the crucial objection to the hypothesis. In this paper I study under which conditions this phenomenon occurs, and discuss its significance for the topics of skepticism and scientific realism. (shrink)

In this paper, I provide an account of subjective epistemic obligations. In instances of peer disagreement, one possesses at least two types of obligations: objective epistemic obligations and subjective epistemic obligations. While objective epistemic obligations, such as conciliationism and remaining steadfast, have been much discussed in the literature, subjective epistemic obligations have received little attention. I develop an account of subjective epistemic obligations in the context of worldview disagreements. In recent literature, the notion of worldview disagreement has been receiving increasing (...) attention, and I discuss how understanding worldview disagreements through different classes of beliefs might clarify our understanding of subjective epistemic obligations. I first distinguish between three classes of beliefs, by virtue of their justificatory functions within worldviews: fundamental, crucial and incidental. I then discuss four kinds of worldview disagreements based on this account. Finally, I argue that each disagreement results in different subjective epistemic obligations for each disputant. I conclude by discussing some implications this analysis has for issues such as defeat, peerhood, and epistemic injustice. (shrink)

What can we know? How should we live? What is there? Philosophers famously diverge in the answers they give to these and other philosophical questions. It is widely presumed that a lack of convergence on these questions suggests that philosophy is not progressing at all, is not progressing fast enough, or is not progressing as fast as other disciplines, such as the natural sciences. Call the view that ideal philosophical progress is marked by at least some degree of convergence on (...) the core philosophical questions the pro-convergence thesis. I will argue that there is reason to reject the pro-convergence thesis in favor of the anti-convergence thesis, the view that significant viewpoint convergence is at odds with the aims of a philosophically ideal community. The argument centers on a thought experiment about two different philosophical communities. (shrink)

“Never attribute to malice that which is adequately explained by stupidity”—so says Hanlon’s Razor. This principle is designed to curb the human tendency toward explaining other people’s behavior by moralizing it. We ask whether Hanlon’s Razor is good or bad advice. After offering a nuanced interpretation of the principle, we critically evaluate two strategies purporting to show it is good advice. Our discussion highlights important, unsettled questions about an idea that has the potential to infuse greater humility and civility into (...) discourse and debate. (shrink)

Extreme Permissivism is the view that a body of evidence could rationally permit both the attitude of belief and disbelief towards a proposition. This paper puts forward a new argument against Extreme Permissivism, which improves on a similar style of argument due to Roger White (2005, 2014). White’s argument is built around the principle that the support relation between evidence and a hypothesis is objective: so that if evidence E makes it rational for an agent to believe a hypothesis H, (...) then E makes it rational to believe H, for all agents. In this paper, I construct a new argument against Extreme Permissivism that appeals to a logically weaker, less demanding view about evidential support, Relational Objectivity: whether a body of evidence E is more likely if H is true than if H is false is an objective matter and does not depend on how any agent interprets the relationship between E and H. Relational Objectivity is solely concerned with the conditional probabilities called likelihoods and does not put substantive constraints on an agent’s prior and posterior credences. For this reason, the presented argument avoids the standard permissivist criticism levelled against White’s argument. (shrink)

Intractable disagreements are commonly analyzed in terms of the semantic opposition of (at least) couples of disputed beliefs (purely epistemic view, from here on PEV). While such a view seems to be a very natural starting point, my intuitions are that such an approach is misleadingly unrealistic, and that an empirical modeling towards how individuals hold beliefs in intractable opposition constitutes a strong defeater for PEV. My work addresses disagreements within the religious domain. Accordingly, I will be concerned with developing (...) my empirical understanding of religious beliefs, and will show the consequences of such proposal on how to answer the problem of religious diversity.

Hinge epistemology has to dispel the worry that disagreeing over hinges is rationally inert. Building on a companion piece (Coliva and Palmira 2020), this paper offers a constitutivist solution to the problem of rational inertia by maintaining that a Humean sceptic and a hinge epistemologist disagree over the correct explication of the concept of epistemic rationality. The paper explores the implications of such a solution. First, it clarifies in what sense a disagreement over hinges would be a conceptual disagreement. Secondly, (...) it uses considerations about the (alleged) rational inertia of hinge disagreement to offer a test whereby to demarcate genuine hinges from merely entrenched beliefs. Thirdly, it offers a response to the challenge of explaining why we have reason to engage in the epistemic practices that hinges are constitutive of in the first place. Fourthly, it argues that the constitutivist approach to hinge disagreement does not result in a relativist view. (shrink)

In this article, I argue that the practice of civil disagreement has robust epistemic benefits and that these benefits enable meaningful forms of reconciliation—across worldview lines and amid the challenging information environment of our age. I then engage two broad groups of objections: either that civil disagreement opposes, rather than promotes, clarity, or else that it does little to help it. If successful, my account gives us reason to include civil disagreement among what Mill calls “the real morality of public (...) discussion,” a fact that should stir us to take more seriously the decline of civility in contemporary life.

English summary: This paper uses research on the COVID-19 pandemic as the backdrop for an accessible discussion of the value and status of science, and of the role of valuesin science. In particular, the paper seeks to debunk three common myths or dogmas about scientific research: (i) that there is such a thing as 'scientific proof' of a theory or hypothesis, (ii) that disagreement is necessarily unhealthy or unnatural in science, (iii) and that personal values play no role in scientific (...) research.

Scientists, philosophers, and other researchers commonly assert their theories. This is surprising, as there are good reasons for skepticism about theories in cutting-edge research. I propose a new account of assertion in research contexts that vindicates these assertions. This account appeals to a distinct propositional attitude called endorsement, which is the rational attitude of committed advocacy researchers have to their theories. The account also appeals to a theory of conversational pragmatics known as the Question Under Discussion model, or QUD. Hence, (...) I call the theory the EQUD model. Motivating this account is a recognition that the speech act of assertion has two roles to play in research contexts. The first is the advocacy role, in which researchers assert a theory in order to advocate for it. The second is the evidential role, which is used to add to the common stock of information available to a field of inquiry. The EQUD model provides an account of warranted assertion for both these roles in research contexts. This success provides support for the theory of endorsement. It also provides support for information updating accounts of assertion. (shrink)

Scientists often diverge widely when choosing between research programs. This can seem to be rooted in disagreements about which of several theories, competing to address shared questions or phenomena, is currently the most epistemically or explanatorily valuable—i.e. most successful. But many such cases are actually more directly rooted in differing judgments of pursuit-worthiness, concerning which theory will be best down the line, or which addresses the most significant data or questions. Using case studies from 16th-century astronomy and 20th-century geology and (...) biology, I argue that divergent theory choice is thus often driven by considerations of scientific process, even where direct epistemic or explanatory evaluation of its final products appears more relevant. Broadly following Kuhn’s analysis of theoretical virtues, I suggest that widely shared criteria for pursuit-worthiness function as imprecise, mutually-conflicting values. However, even Kuhn and others sensitive to pragmatic dimensions of theory ‘acceptance’, including the virtue of fruitfulness, still commonly understate the role of pursuit-worthiness—especially by exaggerating the impact of more present-oriented virtues, or failing to stress how ‘competing’ theories excel at addressing different questions or data. This framework clarifies the nature of the choice and competition involved in theory choice, and the role of alternative theoretical virtues. (shrink)

Sometimes citizens disagree about political matters, but a decision must be made. We have two theoretical frameworks for resolving political disagreement. The first is the framework of social choice. In it, our goal is to treat parties to the dispute fairly, and there is no sense in which some are right and the others wrong. The second framework is that of collective decision-making. Here, we do believe that preferences are truth apt, and our moral consideration is owed not to those (...) who disagree but to the community that stands to benefit or suffer from the decision. In this chapter, I describe and explore these two frameworks. I conclude two things. First, analysis of real-world disagreement suggests that collective decision-making is the right way to model politics. In most, possibly even all, political disagreement, all parties believe (if implicitly) that there is an objective standard of correctness. Second, this matter is connected to the concept of pluralism. If pluralism is true, then collective decision-making cannot be applied to some political disagreements. More surprisingly, pluralism may rule out the applicability of social choice theory as well. (shrink)

It is often suggested that when opinions differ among individuals in a group, the opinions should be aggregated to form a compromise. This paper compares two approaches to aggregating opinions, linear pooling and what I call opinion agglomeration. In evaluating both strategies, I propose a pragmatic criterion, No Regrets, entailing that an aggregation strategy should prevent groups from buying and selling bets on events at prices regretted by their members. I show that only opinion agglomeration is able to satisfy the (...) demand. I then proceed to give normative and empirical arguments in support of the pragmatic criterion for opinion aggregation, and that ultimately favor opinion agglomeration. (shrink)

The purpose of the paper is to analyze the thesis that an agreement between representatives of two different cultures can and should be reached at a theoretical level. The author tries to verify the Theory of Communicative Action proposed by Jürgen Habermas in the light of philosophical reflections of American neopragmatist Stanley Fish. Habermas is one of the most important and widely read social theorists in the post-Second World War era. He is also one of the authors of the concept (...) of deliberative democracy, which holds that, for a democratic decision to be legitimate, it must be preceded by authentic deliberation – disinterested exchange of reasons – not merely the aggregation of preferences that occurs in voting. The foundation of deliberative democracy is, according to the German thinker, a communicative action based on communicative rationality. Stanley Fish, in turn, is one of the most eminent American philosophers of the twentieth and twenty-first centuries. The main area of his scientific activity is the theory of literature, law, and history. In the course of his reflections, Fish constructed the concept of an interpretive communities, which implies an original view on the nature of the process of cognition, status of human convictions or beliefs, nature of communication situation and capabilities of theory. The final conclusion stemming from the reflection on Fish’s philosophy explains why Habermas’ theory is not an adequate tool to reach an intercultural agreement. (shrink)

This paper reviews current debates in social epistemology about the relations ‎between ‎knowledge ‎and consensus. These relations are philosophically interesting on their ‎own, but ‎also have ‎practical consequences, as consensus takes an increasingly significant ‎role in ‎informing public ‎decision making. The paper addresses the following questions. ‎When is a ‎consensus attributable to an epistemic community? Under what conditions may ‎we ‎legitimately infer that a consensual view is knowledge-based or otherwise ‎epistemically ‎justified? Should consensus be the aim of scientific inquiry, and (...) if so, what ‎kind of ‎consensus? How should dissent be handled? It is argued that a legitimate inference ‎that a ‎theory is correct from the fact that there is a scientific consensus on it requires taking ‎into ‎consideration both cognitive properties of the theory as well as social properties of ‎the ‎consensus. The last section of the paper reviews computational models of ‎consensus ‎formation.‎. (shrink)

This paper addresses a largely neglected question in ongoing debates over disagreement: what is the relation, if any, between disagreements involving credences and disagreements involving outright beliefs? The first part of the paper offers some desiderata for an adequate account of credal and full disagreement. The second part of the paper argues that both phenomena can be subsumed under a schematic definition which goes as follows: A and B disagree if and only if the accuracy conditions of A's doxastic attitude (...) are such that, if they were fulfilled, this would ipso facto make B's doxastic attitude inaccurate, or vice-versa.

The recent debate on Semantic Contextualism and Relativism has definitely brought the phenomenon of disagreement under the spotlight. Relativists have considered disagreement as a means to accomplish a defence of their own position regarding the semantics of knowledge attributions, epistemic modals, taste predicates, and so on. The aim of this paper is twofold: first, we argue that several specific notions of disagreement can be subsumed under a common “schema” which provides a unified and overarching notion of disagreement. Secondly, we avail (...) ourselves of such a unified notion of disagreement to assess the arguments devised especially by Relativists in order to criticise certain forms of Contextualism, which crucially rely on the idea that Relativism is better suited than Contextualism to capture certain intuitions of disagreement.

The present paper deals with the consequences Kripke’s interpretation of Wittgenstein’s private language argument has for political and social thought. We will show this is particularly important because it challenges the framework where ordinarily is located the discussion of the political and social relevance of Wittgenstein’s thought. Classical discussion has been concerned mainly with the role of communitary agreement, its relativistic or conservative consequences, the room for criticism and disagreement that it leaves, etc. We discern in classical reading a commitment (...) with some epistemological problems (warrants for knowledge) which is not completely overcame, its semantic jargon notwithstanding. Instead, we will argue, the new framework proposed by Kripke, overcome this epistemological problematic, rising new concerns, close to which, in French contemporary thought, has been called “philosophies of the subjection of the subject”.

Public deliberation has been defended as a rational and noncoercive way to overcome paradoxical results from democratic voting, by promoting consensus on the available alternatives on the political agenda. Some critics have argued that full consensus is too demanding and inimical to pluralism and have pointed out that single-peakedness, a much less stringent condition, is sufficient to overcome voting paradoxes. According to these accounts, deliberation can induce single-peakedness through the creation of a ‘meta-agreement’, that is, agreement on the dimension according (...) to which the issues at stake are ‘conceptualized’. We argue here that once all the conditions needed for deliberation to bring about single-peakedness through meta-agreement are unpacked and made explicit, meta-agreement turns out to be a highly demanding condition, and one that is very inhospitable to pluralism.

Western liberal democracies praise themselves for protecting a full range of differences among individuals and groups. The origin of this ongoing process is thought to be Locke’s Epistola de Tolerantia. Before the Reformation, it is assumed, “a multiplicity of beliefs was deemed to be dangerous, as well as evil; diversity was, so to speak, the devil’s work, and where it existed it was to be stamped out”. Yet, although flattering to liberalism, the conceit of a modern liberal discovery of liberty (...) of conscience is both conceptually simplistic and historically misleading. The main virtue of this volume is to challenge this tale of Western political history. The essays presented seek to demonstrate that premodern thinkers generated alternative theories of toleration; and to contribute to a philosophical analysis of tolerance. (shrink)

In this paper, I discuss the analysis of logic in the pragmatic approach recently proposed by Brandom. I consider different consequence relations, formalized by classical, intuitionistic and linear logic, and I will argue that the formal theory developed by Brandom, even if provides powerful foundational insights on the relationship between logic and discursive practices, cannot account for important reasoning patterns represented by non-monotonic or resource-sensitive inferences. Then, I will present an incompatibility semantics in the framework of linear logic which allow (...) to refine Brandom’s concept of defeasible inference and to account for those non-monotonic and relevant inferences that are expressible in linear logic. Moreover, I will suggest an interpretation of discursive practices based on an abstract notion of agreement on what counts as a reason which is deeply connected with linear logic semantics. (shrink)

The metalinguistic approach to conceptual engineering construes disputes between linguistic reformers and linguistic conservatives as metalinguistic disagreements on how best to use particular expressions. As the present paper argues, this approach has various merits. However, it was recently criticised in Cappelen’s seminal Fixing Language. Cappelen raises an important objection against the metalinguistic picture. According to this objection – the Babel objection, as I shall call it – the metalinguistic account cannot accommodate the intuition of disagreement between linguistic conservatives and reformers (...) who are speaking different languages. The objection generalises to metalinguistic approaches to e.g. moral disagreements. This paper discusses the Babel objection and shows how to dispel it. (shrink)

The fog of war—poor intelligence about the enemy—can frustrate even a well-prepared military force. Something similar can happen in intellectual debate. What I call the *fog of debate* is a useful metaphor for grappling with failures and dysfunctions of argumentative persuasion that stem from poor information about our opponents. It is distressingly easy to make mistakes about our opponents’ thinking, as well as to fail to comprehend their understanding of and reactions to our arguments. After describing the fog of debate (...) and outlining its sources in cognition and communication, I consider a few policies we might adopt upon learning we are in this fog. (shrink)

Many philosophers regard the persistence of philosophical disputes as symptomatic of overly ambitious, ill-founded intellectual projects. There are indeed strong reasons to believe that persistent disputes in philosophy (and more generally in the discourse at large) are pointless. We call this the pessimistic view of the nature of philosophical disputes. In order to respond to the pessimistic view, we articulate the supporting reasons and provide a precise formulation in terms of the idea that the best explanation of persistent disputes entails (...) that they are pointless. We then show how to answer the pessimistic argument. Taking a well-known mathematical controversy as our paradigm example, we argue that some persistent disputes reflect substantive disagreements at the “meta-analytic” level, i.e., disagreements about the best way, among quite different candidates, to understand the topic at issue, and the best associated cluster of analytic truths one should accept concerning it. Moreover, our concrete example shows that such meta-analytic disagreements can in principle be settled and yield a genuine theoretical (as opposed to merely pragmatic) breakthrough. We conclude optimistically that persistent disputes can be an important means of fostering epistemic progress. (shrink)

The thesis of quantifier variance is consistent and cannot be refuted via a collapse argument.

In this article, we discuss a simple argument that modal metaphysics is misconceived, and responses to it. Unlike Quine’s, this argument begins with the banal observation that there are different candidate interpretations of the predicate ‘could have been the case’. This is analogous to the observation that there are different candidate interpretations of the predicate ‘is a member of’. The argument then infers that the search for metaphysical necessities is misguided in much the way the ‘set-theoretic pluralist’ (Clarke-Doane & Hamkins (...) [2017]) claims that the search for the true axioms of set theory is. We show that the obvious responses to this argument fail. However, a new response has emerged that purports to prove, from higher order logical principles, that metaphysical possibility is the broadest kind of possibility applying to propositions, and is to that extent special. We distill two lines of reasoning from the literature, and argue that their import depends on premises that a ‘modal pluralist’ should deny. Both presuppose that there is a unique typed hierarchy, which is what the modal pluralist, in the context of higher-order logic, should disavow. In other words, both presupposes that there is a unique candidate for what higher-order claims could mean. We consider the worry that, in a higher-order setting, modal pluralism faces an insuperable problem of articulation, collapses into modal monism, is vulnerable to the Russell-Myhill paradox, or even contravenes the truism that there is a unique actual world, and argue that these worries are misplaced. We also sketch the bearing of the resulting ‘Higher Order Pluralism’ on the theory of content. One upshot is that, if Higher Order Pluralism is true, then there is no fixed metatheory from which to characterize higher order reality. (shrink)

Verbal disputes are often seen as closely related to a lack of substantivity. However, a systematic and comprehensive investigation of how verbalness relates to substantivity is still missing. The present paper attempts to close this gap. In addition to offering different conceptions of verbalness, the paper further develops Sider’s (2011) notion of substantivity. Ultimately, I argue for a more careful choice of terminology when it comes to assessing a dispute as “(merely) verbal” or “nonsubstantive”. While the paper shows that there (...) is no strict logical relation between mere verbalness and nonsubstantivity construed along the lines set out by Sider, it also demonstrates that further notable notions of (mere) verbalness and substantivity are in fact closely intertwined.

The method of supergrading is introduced for deriving a ranking of items from scores or grades awarded by several people. Individual inputs may come in different languages of grades. Diversity in grading standards is an advantage, enabling rankings derived by this method to separate more items from one another. A framework is introduced for studying grading on the basis of observations. Measures of accuracy, reliability and discrimination are developed within this framework. Ability in grading is characterized for individuals and groups (...) as the capacity to grade reliably, accurately and at a high level of discrimination. It is shown that the collective ability of a supergrading group with diverse standards can be greater than that of a less diverse group whose members have greater ability. (shrink)

A central dispute in social ontology concerns the existence of group minds and actions. I argue that some authors in this dispute rely on rival views of existence without sufficiently acknowledging this divergence. I proceed in three steps in arguing for this claim. First, I define the phenomenon as an implicit higher-order disagreement by drawing on an analysis of verbal disputes. Second, I distinguish two theories of existence—the theory-commitments view and the truthmaker view—in both their eliminativist and their constructivist variants. (...) Third, I examine individual contributions to the dispute about the existence of group minds and actions to argue that these contributions have an implicit higher-order disagreement. This paper serves two purposes. First, it is a study to apply recent advances in meta-ontology. Second, it contributes to the debate on social ontology by illustrating how meta-ontology matters for social ontology. (shrink)

According to standard assumptions in semantics, ordinary users of a language have implicit beliefs about the truth-conditions of sentences in that language, and they often agree on those beliefs. For example, it is assumed that if Anna and John are both competent users of English and the former utters ‘grass is green’ in conversation with the latter, they will both believe that that sentence is true if and only if grass is green. These assumptions play an important role in an (...) intuitively compelling picture of communication, according to which successful communication through literal assertoric utterances is normally effected thanks to our shared beliefs about the truth-conditions of the sentences uttered in the course of the conversation. Against these standard assumptions, this paper argues that the participants in a conversation rarely have the same beliefs about the truth-conditions of the sentences involved in a linguistic interaction. More precisely, it argues for Variance, the thesis that nearly every utterance is such that there is no proposition which more than one language user believes to be that utterance’s truth-conditional content. If Variance is true, we must reject the standard picture of communication. Towards the end of the paper I identify three ways in which ordinary conversations can be communication-like despite the truth of Variance and argue that the most natural amendments to the standard picture fail to explain them.

The terms ‘compatibilism’ and ‘incompatibilism’ were introduced in the mid-20th century to name conflicting views about the in-principle relationship between the thesis of determinism and the thesis that someone has free will. These technical terms were originally introduced within a specific research paradigm, the classical analytic paradigm, but few free-will theorists still work within that paradigm (i.e. using its methods, granting its substantive background assumptions, etc.). This chapter discusses how the ambiguity of the terms ‘incompatibilism’ and ‘compatibilism’ took root. I (...) also explain why the ambiguity of these anachronistic terms, though relatively innocuous when they were first introduced, is now keeping us from clearly identifying the major positions and battle lines in the contemporary free-will debate. -/- For a copy of the penultimate draft, please gmail me at: kristin.mickelson.42.

There seem to be cases where A believes p, and B believes not-p, but neither makes a mistake. This is known as faultless disagreement. According to the epistemic account, in at least some cases of faultless disagreement either A or B must believe something false, and the disagreement is faultless in the sense that each follows the epistemic norm. Recently, philosophers have raised various objections to this account. In this paper, I propose a new version of the epistemic account and (...) show how it can handle those objections. (shrink)

Philosophers of language and metaethicists are concerned with persistent normative and evaluative disagreements – how can we explain persistent intelligible disagreements in spite of agreement over the described facts? Tim Sundell recently argued that evaluative aesthetic and personal taste disputes could be explained as metalinguistic negotiations – conversations where interlocutors negotiate how best to use a word relative to a context. I argue here that metalinguistic negotiations are neither necessary nor sufficient for genuine evaluative and normative disputes to occur. A (...) comprehensive account of value talk requires stronger metanormative commitments than metalinguistic negotiations afford. (shrink)

The traditional use of the expression 'pseudoproblem' is analysed in order to clarify the talk of pseudoproblems and related phenomena. The goal is to produce a philosophically serviceable terminology that stays true to its historical roots. This explicative study is inspired by and makes use of the method of logical reconstruction. Since pseudoproblems are usually expressed by pseudoquestions a formal language of questions is presented as a possible reconstruction language for alleged pseudoproblems. The study yields an informal theory of pseudoproblems (...) whose presuppositions are critically investigated right away. At least one result remains: Claims of pseudoproblemship and their refutations must not be voiced casually - they are to be relativized and need substantial interpretive effort. (shrink)

The idea that certain philosophical debates are "merely verbal" has historically been raised as a challenge against (large parts of) metaphysics. In this paper, I explore an analogous challenge to large parts of epistemology, which is motivated by recent arguments in experimental philosophy. I argue that, while this challenge may have some limited success, it cannot serve as a wedge case for wide-ranging skepticism about the substantiveness of epistemological debates; most epistemological debates are immune to the worries it raises.

An error theorist about a particular discourse combines the cognitivist thesis that the discourse is truth-apt with the thesis that core statements asserted by the discourse are false. For instance, one is an error theorist about witch discourse if one thinks that witch discourse is truth-apt and that some of the entities and properties quantified over by core statements in the discourse, namely witches and magical powers, do not exist and hence that certain core statements of the discourse are false.

My focus here will be Rudolf Carnap’s views on ontology, as these are presented in the seminal “Empiricism, Semantics and Ontology” (1950). I will first describe how I think Carnap’s distinction between external and internal questions is best understood. Then I will turn to broader issues regarding Carnap’s views on ontology. With certain reservations, I will ascribe to Carnap an ontological pluralist position roughly similar to the positions of Eli Hirsch and the later Hilary Putnam. Then I turn to some (...) interrelated arguments against the pluralist view. The arguments are not demonstrative. Some possible escape routes for the pluralist are outlined. But I think the arguments constitute a formidable challenge. There should be serious doubt as to whether the pluralist view, as it emerges after discussion of these arguments, will be worth defending. Moreover, there is an alternative ontological view which equally well subserves the motivations underlying ontological pluralism. (shrink)

In Naming and Necessity, Saul Kripke employs a handy philosophical trick: he invents the term ‘schmidentity’ to argue indirectly for his favored account of identity. Kripke says in a footnote that he wishes someday “to elaborate on the utility of this device”. In this paper, I first take up a general elaboration on his behalf. I then apply the trick to support an attractive but somewhat unorthodox picture of conceptual analysis—one according to which it is a process of forming intentions (...) for word use. This picture can recover a naturalistically respectable notion of the philosopher’s task, and can help resolve current debates that turn on the place of conceptual analysis. (shrink)

How should your opinion change in response to the opinion of an epistemic peer? We show that the pooling rule known as "upco" is the unique answer satisfying some natural desiderata. If your revised opinion will influence your opinions on other matters by Jeffrey conditionalization, then upco is the only standard pooling rule that ensures the order in which peers are consulted makes no difference. Popular proposals like linear pooling, geometric pooling, and harmonic pooling cannot boast the same.

In the contemporary epistemological literature, peer disagreement is often taken to be an instance of a more general phenomenon of “higher-order evidence.” Correspondingly, its epistemic significance is often thought to turn on the epistemic significance of higher-order evidence in general. This chapter attempts to evaluate this claim, and in doing so to clarify some points of unclarity in the current literature – both about what it is for evidence to be “higher-order,” and about the relationship between disagreement and higher-order evidence. (...) We will begin by considering some candidate definitions of “higher-order evidence,” and offering our own definition that attempts to capture the phenomenon of interest. We will then consider, in light of this definition, whether disagreement and its epistemic significance are best-understood as a kind of higher-order evidence. We’ll argue that although peer disagreement can be epistemically significant qua higher-order evidence, this role doesn’t exhaust its significance, and that it can also serve as straightforward first-order evidence. Finally, we’ll suggest that inattention to this latter point has made broadly conciliatory views about peer disagreement seem somewhat easier to resist than they in fact are. (shrink)
