Political liberalism holds that political decisions should be made on the basis of public considerations, and not on the basis of comprehensive religious, moral, or philosophical views. An important objection to this view is that it presupposes doubt, hesitation, or skepticism about the truth of comprehensive doctrines on the side of reasonable citizens. Proponents of political liberalism, such as John Rawls and Jonathan Quong, successfully defend political liberalism against several objections of this kind. In this paper, I argue that recent (...) developments in the epistemology of disagreement require us to revisit these skeptical concerns. I will argue that the correct understanding of political liberalism’s epistemic commitments, in combination with a conciliatory view about peer disagreement, lead to a new skeptical problem for political liberalism. All reasonable citizens who also hold a set of religious, moral, or philosophical beliefs, I will argue, suffer from a breakdown of epistemic rationality. I will show that existing answers to skeptical objections fail to resolve this problem. (shrink)

The central question of the peer disagreement debate is: what should you believe about the disputed proposition if you have good reason to believe that an epistemic peer disagrees with you? This article shows that this question is ambiguous between evidential support (or propositional justification) and well-groundedness (or doxastic justification). The discussion focuses on conciliatory views, according to which peer disagreements require you to significantly revise your view or to suspend judgment. The article argues that for a wide range of (...) conceptions of evidential support, conciliatory views are false if they are understood entirely in terms of evidential support. Alternative conceptions of evidential support face some serious difficulties. These arguments speak against conciliationism, but the article then goes on to defend a conciliatory view about well-grounded belief: when you believe p, and you have good reason to believe that your epistemic peer disagrees with you, you are not justified in believing p because that belief is no longer well grounded. This picture of the epistemology of peer disagreement offers a reconciliation of some of the main competing views in the literature: conciliationism is true when we look at well-grounded belief, but a nonconciliatory view like Thomas Kelly's “total evidence view” is correct when we look at peer disagreement exclusively in terms of evidential support.

The paper presents and defends a Bayesian theory of trust in social networks. In the first part of the paper, we provide justifications for the basic assumptions behind the model, and we give reasons for thinking that the model has plausible consequences for certain kinds of communication. In the second part of the paper we investigate the phenomenon of overconfidence. Many psychological studies have found that people think they are more reliable than they actually are. Using a simulation environment that (...) has been developed in order to make our model computationally tractable we show that in our model inquirers are indeed sometimes better off from an epistemic perspective overestimating the reliability of their own inquiries. We also show, by contrast, that people are rarely better off overestimating the reliability of others. On the basis of these observations we formulate a novel hypothesis about the value of overconfidence. (shrink)

Philosophical responses to religious diversity range from outright rejection of divine reality to claims of religious pluralism. In this paper, I challenge those responses that take the problem of religious diversity to be merely an instance of the general problem of disagreement. To do so, I will take, as my starting point, William Alston’s treatment of the problems that religious diversity seems to pose for the rationality of theistic beliefs. My main aim is to highlight the cognitive penetrability of religious (...) experience as a major source of such problems. I conclude by examining the consequences of cognitive penetration for the reliability of the monotheistic doxastic practice. (shrink)

Current responses to the question of how one should adjust one’s beliefs in response to peer disagreement have, in general, formed a spectrum at one end of which sit the so-called ‘conciliatory’ views and whose other end is occupied by the ‘steadfast’ views. While the conciliatory views of disagreement maintain that one is required to make doxastic conciliation when faced with an epistemic peer who holds a different stance on a particular subject, the steadfast views allow us to maintain our (...) confidence in our relevant beliefs. My aim in this paper is not to adjudicate between these views. Rather, I shall focus on a particular strategy, namely, denying the appearance of epistemic symmetry between peers, that the steadfast views standardly invoke in support of their position. Having closely examined certain representative examples of the steadfast approach, I will argue that this strategy is fundamentally flawed. (shrink)

One recent topic of debate in Bayesian epistemology has been the question of whether imprecise credences can be rational. I argue that one account of imprecise credences, the orthodox treatment as defended by James M. Joyce, is untenable. Despite Joyce’s claims to the contrary, a puzzle introduced by Roger White shows that the orthodox account, when paired with Bas C. van Fraassen’s Reflection Principle, can lead to inconsistent beliefs. Proponents of imprecise credences, then, must either provide a compelling reason to (...) reject Reflection or admit that the rational credences in White’s case are precise. (shrink)

Standpoint epistemology is committed to the view that some epistemic advantage can be drawn from the position of powerlessness. Call this theepistemic privilege thesis. This thesis stands in need of explication and support. In providing that explication and support, I first distinguish between two readings of the thesis: the thesis that marginalized social locations confer some epistemic advantages (the epistemic advantage thesis) and the thesis that marginalized standpoints generate better, more accurate knowledge (the standpoint thesis). I then develop the former (...) by appealing to the notion of epistemic peers available in the disagreement literature. I next turn to the latter thesis, arguing that consciousness-raising plays an analogous role in the achievement of a standpoint as training does in the achievement of expertise. The upshot of this analysis is that it clarifies that while marginalization is necessary (though not sufficient) for epistemic advantage, it is neither necessary nor sufficient for epistemic privilege.

Can disagreement with my past self about aesthetic matters give a reason to reconsider my present aesthetic verdict and if it does, under what conditions? In other words, can such a disagreement be a sign of my failing in my present aesthetic judgement? In this paper, I argue that revising one’s judgement in response to disagreeing with one’s former self is appropriate but only when the former and the present self share the same aesthetic personality. The possibility of failure in (...) one’s aesthetic judgement is therefore bound up, among other things, with facts about one’s aesthetic identity over time. The resulting view has implications for our understanding of the scope of the autonomy in aesthetics and is consistent with empirical evidence regarding the way in which people evaluate aesthetic judgments.

Responding to Cappelen and Dever’s claim that there is no distinctive role for perspectivality in epistemology, I argue that facts about the outcomes of one’s own reasoning processes may have a different evidential significance than facts about the outcomes of others’.

Higher-order evidence appears to have the ability to defeat rational belief. It is not obvious, however, why exactly the defeat happens. In this paper, I consider two competing explanations of higher-order defeat: the “Objective Higher-Order Defeat Explanation” and the “Subjective Higher-Order Defat Explanation.” According to the former explanation, possessing sufficiently strong higher-order evidence to indicate that one’s belief about p fails to be rational is necessary and sufficient for defeating one’s belief about p. I argue that this type of explanation (...) is defective or at best collapses into the other type of explanation. According to the latter explanation, Believing that one’s belief about p fails to be rational (in response to higher-order evidence about p) is necessary and sufficient for defeating one’s belief about p. I argue that this type of explanation is better suited to explain higher-order defeat given that what one is rational to believe partly depends on the relations among one’s doxastic attitudes. Finally, I address an peculiar feature of the Subjective Higher-Order Defeat Explanation: higher-order defeat becomes contingent on one’s response to the higher-order evidence. (shrink)

Consider two people who disagree about some important claim (e.g. the future moral and political consequences of current U.S. economic policy are X). They each believe the other person is in possession of relevant evidence, is roughly equally competent to evaluate that evidence, etc. From the epistemic point of view, how should such recognized disagreement affect their doxastic attitude toward the original claim? Recent research on the epistemology of disagreement has converged upon three general ways of answering this question. The (...) focus of this article is twofold: first, we summarize and give a brief evaluation of the main accounts of the epistemic significance of disagreement; then, we look at what these accounts suggest about how to epistemically assess both inter-religious and intra-religious disagreements. A final section offers recommendations for further research. (shrink)

Global meta-philosophical skepticism (i.e. completely unrestricted skepticism about philosophy) based upon disagreement faces the problem of self-defeat since it undercuts its motivating conciliatory principle. However, the skeptic may easily escape this threat by adopting a more modest kind of skepticism, that will be called “extensive meta-philosophical skepticism”, i.e., the view that most of our philosophical beliefs are unjustified, except our beliefs in epistemically fundamental principles. As I will argue in this paper, this kind of skepticism is well-motivated, does not undercut (...) the conciliatory principle, but still poses a radical challenge to philosophy as a cognitive discipline. Moreover, I will argue that non-global skepticism that is still extensive undermines itself as well. The deeper reason for this is that this more modest kind of skepticism can only be motivated by the assumption that disagreement with philosophical peers is abundant and that we can identify peers only by relying on track-record arguments. But then one can argue for extensive meta-philosophical skepticism only if one presupposes that those philosophical beliefs that form the basis of track-record evaluations are justified. Here, the threat of self-defeat looms again. I will proceed by first defending the premises of this new anti-skeptical argument against standard objections from the literature. Second, I will show in more detail where the epistemic inconsistency arises in the argument for extensive meta-philosophical skepticism. I conclude with an assessment of the scope and the limits of my argument. (shrink)

In this paper, I argue that the two most common views of how to respond rationally to peer disagreement–the Total Evidence View (TEV) and the Equal Weight View (EWV)–are both inadequate for substantial reasons. TEV does not issue the correct intuitive verdicts about a number of hypothetical cases of peer disagreement. The same is true for EWV. In addition, EWV does not give any explanation of what is rationally required of agents on the basis of sufficiently general epistemic principles. I (...) will then argue that there is a genuine alternative to both views–the Preemption View (PV)–that fares substantially better in both respects. I will give an outline and a detailed defense of PV in the paper. (shrink)

I argue that, in an important range of cases, judging that one disagrees with an epistemic peer requires attributing, either to one's peer or to oneself, a failure of rationality. There are limits, however, to how much irrationality one can coherently attribute, either to oneself or to another. I argue that these limitations on the coherent attribution of rational error put constraints on permissible responses to peer disagreement. In particular, they provide reason to respond to one-off disagreements with a single (...) peer by maintaining one's beliefs, and they provide reason to moderate one's beliefs when faced with repeated disagreement, or disagreement with multiple peers. Finally, I argue that, though peer disagreement is rare, the occasions on which it does occur tend to be especially important, and the kind of response supported here is correspondingly important. In particular, how leading researchers spend their time and effort depends, in part, on how they respond to peer disagreement. And only a response of the kind supported here strikes the right balance between allowing individual researchers to freely pursue what seems to them to be worthwhile projects, and requiring that they pursue those research projects that the community of experts as a whole believes to be likely to yield significant results.

Sinan Dogramaci has recently developed a view according to which the function of epistemic evaluations—like calling someone’s behavior “rational” or “irrational”—is to encourage or discourage the behavior evaluated. This view promises to explain the rational authority of testimony, by describing a social practice that promotes the coordination of epistemic procedures across a community. We argue that Dogramaci’s view is unsatisfactory, for two reasons. First, the social practice at its heart is vulnerable to free riders. Second, even if the problem of (...) free riders can be solved, it “alienates” epistemic agents from the testimony that they receive, in that, though they will accept testimony from their fellows, they will have no reason to do so. We argue that a more satisfactory view can be had if we couple the genuine insights that are to be found in Dogramaci’s proposal with the recognition that testimony is an excludible good that is often distributed according to market forces. It is this fact about test.. (shrink)

ABSTRACTShould conciliating with disagreeing peers be considered sufficient for reaching rational beliefs? Thomas Kelly argues that when taken this way, Conciliationism lets those who enter into a disagreement with an irrational belief reach a rational belief all too easily. Three kinds of responses defending Conciliationism are found in the literature. One response has it that conciliation is required only of agents who have a rational belief as they enter into a disagreement. This response yields a requirement that no one should (...) follow. If the need to conciliate applies only to already rational agents, then an agent must conciliate only when her peer is the one irrational. A second response views conciliation as merely necessary for having a rational belief. This alone does little to address the central question of what is rational to believe when facing a disagreeing peer. Attempts to develop the response either reduce to the first response, or deem necessary an unnecessary doxastic revision, or imply that rational dilemmas obtain in cases where intuitively there are none. A third response tells us to weigh what our pre-disagreement evidence supports against the evidence from the disagreement itself. This invites epistemic akrasia. (shrink)

Having direct doxastic control would not be particularly desirable if exercising it required a failure of epistemic rationality. With that thought in mind, recent writers have invoked the view that epistemic rationality gives us options to defend the possibility of a significant form of direct doxastic control. Specifically, they suggest that when the evidence for p is sufficient but not conclusive, it would be epistemically rational either to believe p or to be agnostic on p, and they argue that we (...) can in these cases effectively decide to form either attitude without irrationality. This paper argues against the version of epistemic permissivism invoked by these writers and shows that other plausible versions of permissivism do not support their cause. It concludes that if we can exercise direct doxastic control without irrationality, it is not because epistemic rationality gives us options. (shrink)

This paper considers a special case of belief updating—when an agent learns testimonial data, or in other words, the beliefs of others on some issue. The interest in this case is twofold: (1) the linear averaging method for updating on testimony is somewhat popular in epistemology circles, and it is important to assess its normative acceptability, and (2) this facilitates a more general investigation of what it means/requires for an updating method to have a suitable Bayesian representation (taken here as (...) the normative standard). The paper initially defends linear averaging against Bayesian-compatibility concerns raised by Bradley (Soc Choice Welf 29:609-632, 2007), as well as problems associated with multiple testimony updates. The resolution of these issues, however, requires an extremely nuanced interpretation of the parameters of the linear averaging model—the so-called weights of respect. We go on to propose a role that the parameters of any 'shortcut' updating function should play, by way of minimal interpretation of these parameters. The class of updating functions that is consistent with this role, however, excludes linear averaging, at least in its standard form. (shrink)

Mizrahi’s argument against Stanford’s challenge to scientific realism is analyzed. Mizrahi’s argument is worth of attention for at least two reasons: unlike other criticisms that have been made to Stanford’s view so far, Mizrahi’s argument does not question any specific claim of Stanford’s argument, rather it puts into question the very coherence of Stanford’s position, because it argues that since Stanford’s argument rests on the problem of the unconceived alternatives, Stanford’s argument is self-defeating. Thus, if Mizrahi’s argument is effective in (...) countering Stanford’s view, it may be able to question the validity of other philosophical positions which similarly rest on the problem of the unconceived alternatives; Mizrahi’s argument against Stanford’s view is in part based on the development of a Stanford-like argument for the field of philosophy. This makes Mizrahi’s argument potentially relevant to the metaphilosophical debate. After careful examination, Mizrahi’s argument against Stanford’s instrumentalism is found wanting. Moreover, a Stanford-like argument is developed, which aims at challenging the metaphilosophical stance implied by Mizrahi’s argument against Stanford’s instrumentalism. (shrink)

We explore which types of probabilistic updating commute with convex IP pooling. Positive results are stated for Bayesian conditionalization, imaging, and a certain parameterization of Jeffrey conditioning. This last observation is obtained with the help of a slight generalization of a characterization of externally Bayesian pooling operators due to Wagner :336–345, 2009). These results strengthen the case that pooling should go by imprecise probabilities since no precise pooling method is as versatile.

I argue against ‘right reason’ style accounts of how we should manage our beliefs in the face of higher-order evidence. I start from the observation that such views seem to have bad practical consequences when we imagine someone acting on them. I then catalogs ways that Williamson, Weatherson, and Lasonen-Aarnio have tried to block objections based on these consequences; I argue all fail. I then move on to offer my own theoretical picture of a rational ‘should believe,’ and show that, (...) if such a picture is right, it can neatly explain why right reason isn't. I close by arguing that the extent to which anti-luminosity arguments motivate right reason has been overstated; the positive picture developed here, despite rejecting right reason, is nonetheless consistent with luminosity failures.

This paper proposes a novel answer to the question of what attitude agents should adopt when they receive misleading higher-order evidence that avoids the drawbacks of existing views. The answer builds on the independently motivated observation that there is a difference between attitudes that agents form as conclusions of their reasoning, called terminal attitudes, and attitudes that are formed in a transitional manner in the process of reasoning, called transitional attitudes. Terminal and transitional attitudes differ both in their descriptive and (...) in their normative properties. When an agent receives higher-order evidence that they might have reasoned incorrectly to a belief or credence towards p, then their attitude towards p is no longer justified as a terminal attitude towards p, but it can still be justified as a transitional attitude. This view, which I call the unmooring view, allows us to capture the rational impact of misleading higher-order evidence in a way that integrates smoothly with a natural picture of epistemic justification and the dynamics of deliberation.

This paper focuses on the question of how to resolve disagreement and uses the Lehrer-Wagner model as a formal tool for investigating consensual decision-making. The main result consists in a general definition of when agents treat each other as epistemic peers (Kelly 2005; Elga 2007), and a theorem vindicating the “equal weight view” to resolve disagreement among epistemic peers. We apply our findings to an analysis of the impact of social network structures on group deliberation processes, and we demonstrate their (...) stability with the help of numerical simulations.

Walter Sinnott-Armstrong has argued against moral intuitionism, according to which some of our moral beliefs are justified without needing to be inferred from any other beliefs. He claims that any prima facie justification some non-inferred moral beliefs might have enjoyed is removed because many of our moral beliefs are formed in circumstances where either (1) we are partial, (2) others disagree with us and there is no reason to prefer our moral judgement to theirs, (3) we are emotional in a (...) way that clouds our judgement, (4) the circumstances are conducive to illusion, or (5) the source of our moral beliefs is unreliable or disreputable. I take issue with the elements of Sinnott-Armstrong’s argument that centre on (1) to (3) and (5), concluding that his case against moral intuitionism is unpersuasive. (shrink)

Plausibly, you should believe what your total evidence supports. But cases of misleading higher-order evidence—evidence about what your evidence supports—present a challenge to this thought. In such cases, taking both first-order and higher-order evidence at face value leads to a seemingly irrational incoherence between one’s first-order and higher-order attitudes: you will believe P, but also believe that your evidence doesn’t support P. To avoid sanctioning tension between epistemic levels, some authors have abandoned the thought that both first-order and higher-order evidence (...) have rational bearing. This sacrifice is both costly and unnecessary. We propose a principle, Evidential Calibration, which requires rational agents to accommodate first-order evidence correctly, while allowing rational uncertainty about what to believe. At the same time, it rules out irrational tensions between epistemic levels. We show that while there are serious problems for some views on which we can rationally believe, “P, but my evidence doesn’t support P”, Evidential Calibration avoids these problems. An important upshot of our discussion is a new way to think about the relationship between epistemic levels: why first-order and higher-order attitudes should generally be aligned, and why it is sometimes—though not always—problematic when they diverge.

This paper is about a problem that can arise when we try to harness the “wisdom of the crowd” from groups comprised of individuals who exhibit a certain kind of epistemic humility in the way they respond to testimonial evidence.

The solution I develop is tentative and may not apply in all circumstances, but it promises to alleviate what seems to me to be a (...) problem of both theoretical interest and practical importance.

Titelbaum Oxford studies in epistemology, 2015) has recently argued that the Enkratic Principle is incompatible with the view that rational belief is sensitive to higher-order defeat. That is to say, if it cannot be rational to have akratic beliefs of the form “p, but I shouldn’t believe that p,” then rational beliefs cannot be defeated by higher-order evidence, which indicates that they are irrational. In this paper, I distinguish two ways of understanding Titelbaum’s argument, and argue that neither version is (...) sound. The first version can be shown to rest on a subtle, but crucial, misconstrual of the Enkratic Principle. The second version can be resisted through careful consideration of cases of higher-order defeat. The upshot is that proponents of the Enkratic Principle are free to maintain that rational belief is sensitive to higher-order defeat. (shrink)

The debate on the epistemology of disagreement has so far focused almost exclusively on cases of disagreement between individual persons. Yet, many social epistemologists agree that at least certain kinds of groups are equally capable of having beliefs that are open to epistemic evaluation. If so, we should expect a comprehensive epistemology of disagreement to accommodate cases of disagreement between group agents, such as juries, governments, companies, and the like. However, this raises a number of fundamental questions concerning what it (...) means for groups to be epistemic peers and to disagree with each other. In this paper, we explore what group peer disagreement amounts to given that we think of group belief in terms of List and Pettit’s ‘belief aggregation model’. We then discuss how the so-called ‘equal weight view’ of peer disagreement is best accommodated within this framework. The account that seems most promising to us says, roughly, that the parties to a group peer disagreement should adopt the belief that results from applying the most suitable belief aggregation function for the combined group on all members of the combined group. To motivate this view, we test it against various intuitive cases, derive some of its notable implications, and discuss how it relates to the equal weight view of individual peer disagreement.

Many epistemologists have endorsed a version of the view that rational belief is sensitive to higher-order defeat. That is to say, even a fully rational belief state can be defeated by misleading higher-order evidence, which indicates that the belief state is irrational. In a recent paper, however, Maria Lasonen-Aarnio calls this view into doubt. Her argument proceeds in two stages. First, she argues that higher-order defeat calls for a two-tiered theory of epistemic rationality. Secondly, she argues that there seems to (...) be no satisfactory way of avoiding epistemic dilemmas within a two-tiered framework. Hence, she concludes that the prospects look dim for making sense of higher-order defeat within a broader theoretical picture of epistemic rationality. Here I aim to resist both parts of Lasonen-Aarnio’s challenge. First, I outline a way of accommodating higher-order defeat within a single-tiered framework, by amending epistemic rules with appropriate provisos for different kinds of higher-order defeat. Secondly, I argue that those who nevertheless prefer to accommodate higher-order defeat within a two-tiered framework can do so without admitting to the possibility of epistemic dilemmas, since epistemic rules are not always accompanied by ‘oughts’ in a two-tiered framework. The considerations put forth thus indirectly vindicate the view that rational belief is sensitive to higher-order defeat. (shrink)

Should you always be certain about what you should believe? In other words, does rationality demand higher-order certainty? First answer: Yes! Higher-order uncertainty can’t be rational, since it breeds at least a mild form of epistemic akrasia. Second answer: No! Higher-order certainty can’t be rational, since it licenses a dogmatic kind of insensitivity to higher-order evidence. Which answer wins out? The first, I argue. Once we get clearer about what higher-order certainty is, a view emerges on which higher-order certainty does (...) not, in fact, license any kind of insensitivity to higher-order evidence. The view as I will describe it has plenty of intuitive appeal. But it is not without substantive commitments: it implies a strong form of internalism about epistemic rationality, and forces us to reconsider standard ways of thinking about the nature of evidential support. Yet, the view put forth promises a simple and elegant solution to a surprisingly difficult problem in our understanding of rational belief. (shrink)

This paper proposes a methodological turn for the epistemology of disagreement, away from focusing on highly idealized cases of peer disagreement and towards an increased focus on disagreement simpliciter. We propose and develop a normative framework for evaluating all cases of disagreement as to whether something is the case independently of their composition—i.e., independently of whether they are between peers or not. The upshot will be a norm of disagreement on which what one should do when faced with a disagreeing (...) party is to improve the epistemic properties of one’s doxastic attitude or, alternatively, hold steadfast.

The Equal Weight View holds that, when we discover we disagree with an epistemic peer, we should give our peer’s judgment as much weight as our own. But how should we respond when we cannot tell whether those who disagree with us are our epistemic peers? I argue for a position I will call the Earn-a-Spine View. According to this view, parties to a disagreement can remain confident, at least in some situations, by finding justifiable reasons to think their opponents (...) are less credible than themselves, even if those reasons are justifiable only because they lack information about their opponents.

Argues that the answer is yes. The epistemic assumptions of moral theory deprive us of resources needed to resist the challenge of moral disagreement, which its practice at the same time makes vivid. The paper ends by sketching a kind of epistemology that can respond to disagreement without skepticism: one in which the fundamental standards of justification for moral belief are biased toward the truth.

In this paper, I argue that many arguments from expert opinion are strong arguments. Therefore, in many cases it is rational to rely on experts since in many cases the fact that an expert says that p makes it highly likely that p is true. I will defend this claim by providing 5 arguments that illuminate and elaborate on 5 crucial claims about expertise. In this way, I aim to undermine recent attempts to establish a rampant scepticism about arguments from (...) expert opinion. (shrink)

In this paper, I present a new account of akrasia based on the idea that human psychology and self-narrativity are more complex and layered than we have traditionally thought. I begin by arguing that, if we have at least some different beliefs, desires, preferences, etc. in different situations, then we can rationally do what we think, at the time of action, is best for, or from the standpoint of, “part of me” while acting contrary to what we think, at the (...) time of action, is best for, or from the more comprehensive standpoint of, “me.” I then argue that many of us do, in fact, think and act this way in everyday life, and that this kind of action satisfies all the criteria for akrasia. Finally, I briefly argue that on my account of akrasia, akratic actions are not necessarily irrational or blameworthy, though they often will be. (shrink)

In this paper I’ll suggest that a certain challenge facing defeatist views about higher-order evidence cannot be met, namely, motivating principles that recommend abandoning belief in cases of higher order defeat, but do not recommend global scepticism. I’ll propose that, ultimately, the question of whether to abandon belief in response to the realization that our belief can’t be recovered from what I’ll call ‘a perspective of doubt’ can’t be answered through rational deliberation aimed at truth or accuracy.

This paper considers contractarianism as a method of justification. The analysis accepts the key tenets of contractarianism: expected utility maximization, unanimity as the criteria of acceptance, and social-scientific uncertainty of modelled agents. In addition to these three features, however, the analysis introduces a fourth feature: a criteria of rational belief formation, viz. Bayesian belief updating. Using a formal model, this paper identifies a decisive objection to contractarian justification. Insofar as contractarian projects approximate the Agreement Model, therefore, they fail to justify (...) their conclusions. Insofar as they fail to approximate the Agreement Model, they must explain which modelling assumption they reject. (shrink)

Moral enhancement is an ostensibly laudable project. Who wouldn’t want people to become more moral? Still, the project’s approach is crucial. We can distinguish between two approaches for moral enhancement: direct and indirect. Direct moral enhancements aim at bringing about particular ideas, motives or behaviors. Indirect moral enhancements, by contrast, aim at making people more reliably produce the morally correct ideas, motives or behaviors without committing to the content of those ideas, motives and/or actions. I will argue, on Millian grounds, (...) that the value of disagreement puts serious pressure on proposals for relatively widespread direct moral enhancement. A more acceptable path would be to focus instead on indirect moral enhancements while staying neutral, for the most part, on a wide range of substantive moral claims. I will outline what such indirect moral enhancement might look like, and why we should expect it to lead to general moral improvement. (shrink)

I consider sophisticated forms of relativism and their effectiveness at responding to the skeptical argument from moral disagreement. In order to do so, I argue that the relativist must do justice to our intuitions about the depth of moral disagreement, while also explaining why it can be rational to be relatively insensitive to such disagreements. I argue that the relativist can provide an account with these features, at least in some form, but that there remain serious questions about the viability (...) of the resulting account. (shrink)

The aim of this paper is to describe a problem for calibrationism: a view about higher order evidence according to which one's credences should be calibrated to one's expected degree of reliability. Calibrationism is attractive, in part, because it explains our intuitive judgments, and provides a strong motivation for certain theories about higher order evidence and peer disagreement. However, I will argue that calibrationism faces a dilemma: There are two versions of the view one might adopt. The first version, I (...) argue, has the implausible consequence that, in a wide range of cases, calibrationism is the only constraint on rational belief. The second version, in addition to having some puzzling consequences, is unmotivated. At the end of the paper I sketch a possible solution. (shrink)

Epistemologists have recently noted a tension between (i) denying access internalism, and (ii) maintaining that rational agents cannot be epistemically akratic, believing claims akin to ‘p, but I shouldn’t believe p’. I bring out the tension, and develop a new way to resolve it. The basic strategy is to say that access internalism is false, but that counterexamples to it are ‘elusive’ in a way that prevents rational agents from suspecting that they themselves are counterexamples to the internalist principles. I (...) argue that this allows us to do justice to the motivations behind both (i) and (ii). And I explain in some detail what a view of evidence that implements this strategy, and makes it independently plausible, might look like. (shrink)

Reductive physicalists typically accept the causal argument for their view. On this score, Tiehen parts ways with his fellow reductive physicalists. Heretically, he argues that reductive physicalists should reject the causal argument. After presenting Tiehen's challenge, I defend the orthodoxy. Although not myself a reductive physicalist, I show how reductive physicalists can resist this challenge to the causal argument. I conclude with a positive suggestion about how reductive physicalists should use the causal argument.

This paper defends the view that discovering that our universe is fine-tuned should make us more confident that other universes exist. My defense exploits a distinction between ideal and non-ideal evidential support. I use that distinction in concert with a simple model to disarm the most influential objection—the this-universe objection—to the view that fine-tuning supports the existence of other universes. However, the simple model fails to capture some important features of our epistemic situation with respect to fine-tuning. To capture these (...) features, I introduce a more sophisticated model. I then use the more sophisticated model to show that, even once those complicating factors are taken into account, fine-tuning should boost our confidence in the existence of other universes.

The Epistemic Objection says that certain theories of time imply that it is impossible to know which time is absolutely present. Standard presentations of the Epistemic Objection are elliptical—and some of the most natural premises one might fill in to complete the argument end up leading to radical skepticism. But there is a way of filling in the details which avoids this problem, using epistemic safety. The new version has two interesting upshots. First, while Ross Cameron alleges that the Epistemic (...) Objection applies to presentism as much as to theories like the growing block, the safety version does not overgeneralize this way. Second, the Epistemic Objection does generalize in a different, overlooked way. The safety objection is a serious problem for a widely held combination of views: “propositional temporalism” together with “metaphysical eternalism”. (shrink)

How should a group with different opinions (but the same values) make decisions? In a Bayesian setting, the natural question is how to aggregate credences: how to use a single credence function to naturally represent a collection of different credence functions. An extension of the standard Dutch-book arguments that apply to individual decision-makers recommends that group credences should be updated by conditionalization. This imposes a constraint on what aggregation rules can be like. Taking conditionalization as a basic constraint, we gather (...) lessons from the established work on credence aggregation, and extend this work with two new impossibility results. We then explore contrasting features of two kinds of rules that satisfy the constraints we articulate: one kind uses fixed prior credences, and the other uses geometric averaging, as opposed to arithmetic averaging. We also prove a new characterisation result for geometric averaging. Finally we consider applications to neighboring philosophical issues, including the epistemology of disagreement. (shrink)
