While many philosophers have agreed that evidence of disagreement is a kind of higher-order evidence, this has not yet resulted in formally precise higher-order approaches to the problem of disagreement. In this paper, we outline a simple formal framework for determining the epistemic significance of a body of higher-order evidence, and use this framework to motivate a novel interpretation of the popular “equal weight view” of peer disagreement—we call it the Variably Equal Weight View (VEW). We show that VEW differs (...) from the standard Split the Difference (SD) interpretation of the equal weight view in almost all cases of peer disagreement, and use our formal framework to explain why SD has seemed attractive but is in fact misguided. A desirable feature of VEW, we argue, is that it gives rise to plausible instances of synergy—an effect whereby the parties to a disagreement should become more (or less) confident in the disputed proposition than any of them were prior to disagreement. Lastly, we show how VEW may be generalized to cases of non-peer disagreement. (shrink)

A proof-theoretic test for paradoxicality was famously proposed by Tennant: a paradox must yield a closed derivation of absurdity with no normal form. Drawing on the remark that all derivations of a given proposition can be transformed into derivations in normal form of a logically equivalent proposition, we investigate the possibility of paradoxes in normal form. We compare paradoxes à la Tennant and paradoxes in normal form from the viewpoint of the computational interpretation of proofs and from the viewpoint of (...) proof-theoretic semantics. (shrink)

Orthodox Bayesianism is a highly idealized theory of how we ought to live our epistemic lives. One of the most widely discussed idealizations is that of logical omniscience: the assumption that an agent’s degrees of belief must be probabilistically coherent to be rational. It is widely agreed that this assumption is problematic if we want to reason about bounded rationality, logical learning, or other aspects of non-ideal epistemic agency. Yet, we still lack a satisfying way to avoid logical omniscience within (...) a Bayesian framework. Some proposals merely replace logical omniscience with a different logical idealization; others sacrifice all traits of logical competence on the altar of logical non-omniscience. We think a better strategy is available: by enriching the Bayesian framework with tools that allow us to capture what agents can and cannot infer given their limited cognitive resources, we can avoid logical omniscience while retaining the idea that rational degrees of belief are in an important way constrained by the laws of probability. In this paper, we offer a formal implementation of this strategy, show how the resulting framework solves the problem of logical omniscience, and compare it to orthodox Bayesianism as we know it.

The aim of this paper is to trace one of the deepest roots of Hegel's concept of history within Kant's doctrine of schematism. I propose to draw a line of continuity between Kant's Einbildungskraft and Hegel's Selbstbewusstsein. The concept of Selbstbewusstsein of the young Hegel is to be understood, in my view, as the moment when the extreme and radical consequences are drawn from the schematism of the first Critique, revised in the light of Kant's reflections on teleology developed in (...) the Critique of Judgment. In this sense, Hegel can be seen as the 'solution' to the rift that opened up in the heart of Western culture during the Enlightenment. (shrink)

In this paper, we present a new semantic framework designed to capture a distinctly cognitive or epistemic notion of meaning akin to Fregean senses. Traditional Carnapian intensions are too coarse-grained for this purpose: they fail to draw semantic distinctions between sentences that, from a Fregean perspective, differ in meaning. This has led some philosophers to introduce more fine-grained hyperintensions that allow us to draw semantic distinctions among co-intensional sentences. But the hyperintensional strategy has a flip-side: it risks drawing semantic distinctions (...) between sentences that, from a Fregean perspective, do not differ in meaning. This is what we call the ‘new problem’ of hyperintensionality to distinguish it from the ‘old problem’ that faced the intensional theory. We show that our semantic framework offers a joint solution to both these problems by virtue of satisfying a version of Frege’s so-called ‘equipollence principle’ for sense individuation. Frege’s principle, we argue, not only captures the semantic intuitions that give rise to the old and the new problem of hyperintensionality, but also points the way to an independently motivated solution to both problems.

The institutionalization of a rights-based proportionality review shares a number of salient features and puzzles with the practice of contestation that the Socrates of the early Platonic dialogues became famous for. Understanding the point of Socratic contestation, and its role in a democratic polity, is also the key to understanding the point of proportionality based rights review. To begin with, when judges decide cases within the proportionality framework they do not primarily interpret authority. They assess reasons. Not surprisingly, they, like (...) Socrates, have been prone to the charge that they offend the values and traditions of the community. The article discusses four types of pathologies that occasionally infect democratic decision-making that rights-based proportionality review is particularly suited to identify. But more basic and equally important is a second kind of justification: Proportionality-based judicial review institutionalizes a right to contest the acts of public authorities and demand a public reasons-based justification. Having a legal remedy that allows for the contestation of acts by public authorities before an impartial and independent court and demanding its justification in terms of public reason is as basic a commitment of liberal democracy as the right to vote. The real question is not whether judicial review is democratically legitimate, but how judicial institutions ought to be structured to best serve their democracy-enhancing and rights protecting purpose. If Socrates was right to insist that the practice of contestation he engaged in deserves the highest praise in a democratic polity, it is equally true that a well structured and appropriately embedded court engaged in rights based proportionality review deserves to be embraced as a vital element of liberal constitutional democracy.

The traditional possible-worlds model of belief describes agents as ‘logically omniscient’ in the sense that they believe all logical consequences of what they believe, including all logical truths. This is widely considered a problem if we want to reason about the epistemic lives of non-ideal agents who—much like ordinary human beings—are logically competent, but not logically omniscient. A popular strategy for avoiding logical omniscience centers around the use of impossible worlds: worlds that, in one way or another, violate the laws (...) of logic. In this paper, we argue that existing impossible-worlds models of belief fail to describe agents who are both logically non-omniscient and logically competent. To model such agents, we argue, we need to ‘dynamize’ the impossible-worlds framework in a way that allows us to capture not only what agents believe, but also what they are able to infer from what they believe. In light of this diagnosis, we go on to develop the formal details of a dynamic impossible-worlds framework, and show that it successfully models agents who are both logically non-omniscient and logically competent.

Evidentialism is the thesis, roughly, that one’s beliefs should fit one’s evidence. The enkratic principle is the thesis, roughly, that one’s beliefs should "line up" with one’s beliefs about which beliefs one ought to have. While both theses have seemed attractive to many, they jointly entail the controversial thesis that self-misleading evidence is impossible. That is to say, if evidentialism and the enkratic principle are both true, one’s evidence cannot support certain false beliefs about which beliefs one’s evidence supports. Recently, (...) a number of epistemologists have challenged the thesis that self-misleading evidence is impossible on the grounds that misleading higher-order evidence does not have the kind of strong and systematic defeating force that would be needed to rule out the possibility of such self-misleading evidence. Here I respond to this challenge by proposing an account of higher-order defeat that does, indeed, render self-misleading evidence impossible. Central to the proposal is the idea that higher-order evidence acquires its normative force by influencing which conditional beliefs it is rational to have. What emerges, I argue, is an independently plausible view of higher-order evidence, which has the additional benefit of allowing us to reconcile evidentialism with the enkratic principle. (shrink)

Do I cause global warming, climate change and their related harms when I go for a leisure drive with my gas-guzzling car? The current verdict seems to be that I do not; the emissions produced by my drive are much too insignificant to make a difference for the occurrence of global warming and its related harms. I argue that our verdict on this issue depends on what we mean by ‘causation’. If we for instance assume a simple counterfactual analysis of (...) causation according to which ‘C causes E’ means ‘if C had not occurred, E would not have occurred’, we must conclude that a single drive does not cause global warming. However, this analysis of causation is well-known for giving counterintuitive results in some important cases. If we instead adopt Lewis’s analysis of causation, it turns out that it is indeterminate whether I cause global warming when I go for a single drive. Still, in contexts where we seek to control or understand global warming, there is a pressure to adopt a more fragile view of this event. When we adopt such a view, it turns out that a single drive does cause global warming. This means that we cannot like Sinnott-Armstrong and Kingston and Sinnott-Armstrong reject the idea that I should refrain from going for a leisure drive simply because such a drive does not cause global warming.

We often have reason to doubt our own ability to form rational beliefs, or to doubt that some particular belief of ours is rational. Perhaps we learn that a trusted friend disagrees with us about what our shared evidence supports. Or perhaps we learn that our beliefs have been afflicted by motivated reasoning or other cognitive biases. These are examples of higher-order evidence. While it may seem plausible that higher-order evidence should impact our beliefs, it is less clear how and (...) why. Normally, when evidence impacts our beliefs, it does so by virtue of speaking for or against the truth of theirs contents. But higher-order evidence does not directly concern the contents of the beliefs that they impact. In recent years, philosophers have become increasingly aware of the need to understand the nature and normative role of higher-order evidence. This is partly due to the pervasiveness of higher-order evidence in human life. But it has also become clear that higher-order evidence plays a central role in many epistemological debates, spanning from traditional discussions of internalism/externalism about epistemic justification to more recent discussions of peer disagreement and epistemic akrasia. This volume brings together, for the first time, a distinguished group of leading and up-and-coming epistemologists to explore a range of issues about higher-order evidence. (shrink)

According to many philosophers and scientists, human sociality is explained by our unique capacity to “share” attitudes with others. The conditions under which mental states are shared have been widely debated in the past two decades, focusing especially on the issue of their reducibility to individual intentionality and the place of collective intentions in the natural realm. It is not clear, however, to what extent these two issues are related and what methodologies of investigation are appropriate in each case. In (...) this article, I propose a solution that distinguishes between epistemic and ontological interpretations of the demand for the conditions of reduction of collective intentionality. While the philosophical debate has contributed important insights into the former, recent advances in the cognitive sciences offer novel resources to tackle the latter. Drawing on Michael Tomasello’s research in the ontogeny of shared intentionality in early instances of interaction based on joint attention, I propose an empirically informed argument of what it would take to address the ontological question of irreducibility, thus making a step forward in the naturalization of collective intentionality.

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)

There are many ways to advance our understanding of the human mind by studying different kinds of sociality. Our aim in this introduction is to situate claims about extended cognition within a broader framework of research on human sociality. We briefly discuss the existing landscape, focusing on ways of defending socially extended cognition. We then draw on resources from the recent literature on the socially extended mind, as well as the literature on collective intentionality, to provide a framework for thinking (...) about the social dimension of individual minds. We then turn to a brief overview of the individualistic approaches advanced by Ludwig and Spaulding in this volume. And we close with a discussion of the transformative role of the social mind in individual life presented by Kern and Moll, as well as the distributed approach to interacting systems defended by Goldstone and Theiner.

We refine the intuitively appealing idea that you are blameworthy for something if it happened because you did not care enough. More formally: you are blameworthy for X (where X may be an action, omission, or outcome) just in case there is the right causal-explanatory relation between your poor quality of will and X. First, we argue that blameworthiness for actions, omissions, and outcomes is concerned with negative differences: you are blameworthy for the fact that X occurred instead of X*, (...) where X is worse than X*. Second, we argue that the way in which your quality of will is poor has to fit what you are blameworthy for. With these refinements, the account already gives intuitively correct verdicts in cases of forgetting, making a negative difference to a nevertheless good result, and doing an action with runaway consequences. We then discuss what the right causal-explanatory relation is and suggest that it is simply causation, understood in the right way. Here, we draw on the account of causation developed in Touborg, The Dual Nature of Causation. According to this account, there are two necessary and jointly sufficient conditions for causation. Roughly, C causes E rather than E* iff (a) C is process-connected to E, and (b) C makes E more secure and E* less secure. With this account of causation, our account of blameworthiness now also gives correct verdicts in omission, pre-emption, and switching cases, Frankfurt-style cases, and collective harm cases.

Based on Kolchinsky and Wolpert’s work on the semantics of autonomous agents, I propose an application of Mathematical Logic and Probability to model cognitive processes. In this work, I will follow Bateson’s insights on the hierarchy of learning in complex organisms and formalize his idea of applying Russell’s Type Theory. Following Weaver’s three levels for the communication problem, I link the Kolchinsky–Wolpert model to Bateson’s insights, and I reach a semantic and conceptual hierarchy in living systems as an explicative model (...) of some adaptive constraints. Due to the generality of Kolchinsky and Wolpert’s hypotheses, I highlight some fundamental gaps between the results in current Artificial Intelligence and the semantic structures in human beings. In light of the consequences of my model, I conclude the paper by proposing a general definition of knowledge in probabilistic terms, overturning de Finetti’s Subjectivist Definition of Probability.

At Peristephanon 2.549-560, Prudentius depicts St. Laurence as consul in a heavenly Rome. This extraordinary passage achieves two purposes. First, it links the celebration of Rome’s conversion to the concluding prayer. By looking toward the martyr in heavenly glory, Prudentius can make his prayer heard despite his separation from the martyr’s body. Laurence’s exaltation also qualifies aristocratic ambitions. Prudentius glories in the Senate’s conversion, but senatorial lifestyles were at odds with his ideals (as Laurence’s denunciation of the rich underscores). By (...) putting Laurence at the apex of the afterlife for which both senators and ascetics longed, Prudentius can rejoice in the conversion of Rome’s élite and still maintain the superiority of ascetical to worldly lifestyles.

When a belief has been influenced, in part or whole, by factors that, by the believer's own lights, do not bear on the truth of the believed proposition, we can say that the belief has been, in a sense, arbitrarily formed. Can such beliefs ever be rational? It might seem obvious that they can't. After all, belief, supposedly, “aims at the truth.” But many epistemologists have come to think that certain kinds of arbitrary beliefs can, indeed, be rational. In this (...) paper, I want to do two things. First, I want to show that the claim that arbitrary beliefs can be rational is inconsistent with the conjunction of two other attractive claims: one saying that rationality requires a certain kind of epistemic immodesty, and one saying that rationality forbids certain kinds of self-ascriptions of epistemic luck. Second, I want to evaluate different ways one might respond to this inconsistent triad. I won't defend any response in particular, but I'll draw out some notable costs and benefits of each response, which may help shed light on the question of whether arbitrary beliefs can be rational.

Many theories of rational action are predicated on the idea that what it is rational to do in a given situation depends, in part, on what it is rational to believe in that situation. In short: they treat epistemic rationality as explanatorily prior to practical rationality. If they are right in doing so, it follows, on pain of explanatory circularity, that epistemic rationality cannot itself be a form of practical rationality. Yet, many epistemologists have defended just such a view of (...) epistemic rationality. According to them, there is no such thing as a distinctively epistemic form of rationality which could be explanatorily prior to practical rationality. Rather, they maintain, there is just one form of rationality—practical rationality—of which epistemic rationality is a species. What to make of this conflict? The aim of this paper is to motivate a view about the relationship between epistemic and practical rationality which resolves the conflict in a way that should be attractive to both sides. The central idea is to ground both epistemic and practical rationality in an independently motivated notion of evidential probability which is itself to be understood in non-normative terms. Doing so, I argue, allows us to unify epistemic and practical rationality in a way that does justice to the idea that what it is rational to do depends, in part, on what it is rational to believe; and to do so in a way that avoids explanatory circularity.

The first Chapter of Nāgārjuna’s Mūlamadhyamakakārikā offers a critique of causation that includes the Abhidharmic category of the ‘four conditions’. Following the South-Asian commentarial tradition, this article discusses the precise relationship between Madhyamaka philosophy and its fundamental Abhidharmic background. What comes to light is a more precise assessment of Madhyamaka ideas about viable conventions, understood as the process of dependent arising. Since this is primarily in the sense of conceptual dependence, it involves sentiency as a necessary causal element, and the (...) relationship between sentiency and conceptuality is highlighted by Nāgārjuna and his commentators. Viable conventions exclude the possibility of a non-contingent core, and the systems and categories that revolve around such non-contingent element (ātman) are discarded by the Madhyamaka even at a conventional level.

Abstract: Nietzsche’s famously wrote that “consciousness is a surface” (EH, Why I am so clever, 9: 97). The aim of this paper is to make sense of this quite puzzling contention—Superficiality, for short. In doing this, I shall focus on two further claims—both to be found in Gay Science 354—which I take to substantiate Nietzsche’s endorsement of Superficiality. The first claim is that consciousness is superfluous—which I call the “superfluousness claim” (SC). The second claim is that consciousness is the source (...) of some deep falsification—which I call the “falsification claim” (FC). I shall start by considering Nietzsche’s notion of consciousness. Here, I shall argue that the kind of consciousness he is concerned with is in fact self-consciousness and that he put forward a higher-order theory of it. Then, I shall address the two claims. Regarding (FC), my proposal will be that, according to Nietzsche, the content of (self-)conscious mental states is falsified in virtue of its being articulated propositionally. Regarding (SC), I shall claim that it is best read as a weak version of epiphenomenalism about conscious causation. In addressing both points, I shall discuss in particular the influential reading of Nietzsche’s theory of consciousness offered by Katsafanas (2005). (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)

According to the prevailing paradigm in social-cognitive neuroscience, the mental states of individuals become shared when they adapt to each other in the pursuit of a shared goal. We challenge this view by proposing an alternative approach to the cognitive foundations of social interactions. The central claim of this paper is that social cognition concerns the graded and dynamic process of alignment of individual minds, even in the absence of a shared goal. When individuals reciprocally exchange information about each other's (...) minds processes of alignment unfold over time and across space, creating a social interaction. Not all cases of joint action involve such reciprocal exchange of information. To understand the nature of social interactions, then, we propose that attention should be focused on the manner in which people align words and thoughts, bodily postures and movements, in order to take one another into account and to make full use of socially relevant information.

The financial crisis that began in the US real-estate market in 2007 and culminated in a global economic slump showed bluntly how wrong financial risk models can be. This state of affairs has triggered a number of reactions and observations at the level of the specification and use of models and at a more conceptual/fundamental level. This article focuses on the epistemic features of such models – namely the nature, source, conditions of validity, structure and limits of the knowledge that (...) ‘well-specified’ models generate – so as to assess models in a balanced way, giving due weight to the fundamental determinants of their output and warning against overestimation of their possibilities; clarify the conditions under which models can be validly applied to economic and social relationships; render intelligible why the degree of accuracy that successful models would require is intrinsically unattainable; better understand models’ failure as evidenced by the crisis; and comment on the policy steps being undertaken to prevent similar financial crisis in the future. The analysis applies the principal tenets of critical realism to the daily preoccupations of risk management professionals and financial regulators alike. It is not intended as an intervention into critical realism. It draws on the works of Tony Lawson and Roy Bhaskar, and revisits relevant aspects of John Maynard Keynes’s work, connecting dots amongst them and marrying economic and philosophical analysis with day-to-day financial risk management and regulatory issues.

Guessing is a familiar activity, one we engage in when we are uncertain of the answer to a question under discussion. It is also an activity that lends itself to normative evaluation: some guesses are better than others. The question that interests me here is what makes for a good guess. In recent work, Dorst and Mandelkern have argued that good guesses are distinguished from bad ones by how well they optimize a tradeoff between accuracy and specificity. Here I argue (...) that Dorst and Mandelkern’s implementation of this idea fails to satisfy some plausible constraints on good guesses, and I develop an alternative implementation that satisfies the relevant constraints. The result is a new account of good guesses which retains the positive aspects of Dorst and Mandelkern’s proposal, but without the drawbacks. (shrink)

Nietzsche vs. Kant? Der siebzehnte Aphorismus aus dem ersten Teil von Menschliches, Allzumenschliches schliesst mit der korrosiven Bemerkung, das Ding an sich [sei] eines homerischen Gelachters werth. Aufgrund dieser Passage nun aber zu vermuten, Nietzsche habe diesen von Kant stammenden Terminus einfach so ad acta gelegt, ware jedoch ubereilt, denn die Auseinandersetzung mit der Unterscheidung zwischen Erscheinung und Ding an sich lasst sich als Konstante durch Nietzsches gesamtes Werk verfolgen. Mattia Riccardi widmet sich in seiner Studie den verschiedenen Positionen, die (...) Nietzsche im Zusammenhang mit dieser Problematik eingenommen hat: von der im Hintergrund der Geburt der Tragodie prasenten Artisten-Metaphysik bis zur radikalen Infragestellung des kantischen Denkmusters in den Jahren nach 1880. Riccardi beschrankt sich aber nicht auf eine historisch akkurate, direkte und indirekte Textquelle mit einbeziehender Rekonstruktion von Nietzsches kampferischer Lekturepraxis. Vielmehr stellen die wiederholt auftretenden Bezuge auf Kants Begrifflichkeit fur ihn ein geeignetes Instrument dar, um die Entfaltung von Nietzsches Denken in aller Scharfe sichtbar zu machen. Die Kritik an Kant wird auf diese Weise zum Ausgangspunkt einer differenzierten Interpretation von Nietzsches perspektivistischer Philosophie der Macht im Sinne einer relationalen Ontologie. Damit versteht sich das Buch auch als Beitrag zur - vor allem im englischsprachigen Raum sehr lebendigen - Debatte um das Verhaltnis Nietzsches zu Kant. (shrink)

Don’t form beliefs on the basis of coin flips or random guesses. More generally, don’t take belief gambles: if a proposition is no more likely to be true than false given your total body of evidence, don’t go ahead and believe that proposition. Few would deny this seemingly innocuous piece of epistemic advice. But what, exactly, is wrong with taking belief gambles? Philosophers have debated versions of this question at least since the classic dispute between William Clifford and William James (...) near the end of the nineteenth century. Here I reassess the normative standing of belief gambles from the perspective of epistemic decision theory. The main lesson of the paper is a negative one: it turns out that we need to make some surprisingly strong and hard-to-motivate assumptions to establish a general norm against belief gambles within a decision-theoretic framework. I take this to pose a dilemma for epistemic decision theory: it forces us to either make seemingly unmotivated assumptions to secure a norm against belief gambles, or concede that belief gambles can be rational after all.

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)

Iris Marion Young presents a social connection model on which those, and only those, who participate in structural processes that produce injustice have a forward-looking responsibility to redress the resulting injustice by challenging the structures that produce it. In Young's view, this is an all-things-considered, albeit discretionary, responsibility. I argue that participation in a structural process that produces injustice is neither necessary nor sufficient for having political responsibilities, and that therefore the social connection model must be rejected. A subtler model (...) is needed, one that depicts participation in a structural process that produces injustice as sufficient for having pro tanto forward-looking responsibilities to redress the process, unless the participating agent satisfies certain excusing conditions. I suggest the intuitive force of the thought that mere participation gives us political responsibilities can be explained by more fundamental considerations. Hastily, we might conclude that all participants have political responsibilities simply because most of them satisfy at least one of the following conditions: they cause injustice to continue, they are morally responsible for injustice, they benefit from injustice, they have communal ties with the victims of injustice, or they have the capacity to redress injustice.

Many theories of rational belief give a special place to logic. They say that an ideally rational agent would never be uncertain about logical facts. In short: they say that ideal rationality requires "logical omniscience." Here I argue against the view that ideal rationality requires logical omniscience on the grounds that the requirement of logical omniscience can come into conflict with the requirement to proportion one’s beliefs to the evidence. I proceed in two steps. First, I rehearse an influential line (...) of argument from the "higher-order evidence" debate, which purports to show that it would be dogmatic, even for a cognitively infallible agent, to refuse to revise her beliefs about logical matters in response to evidence indicating that those beliefs are irrational. Second, I defend this "anti-dogmatism" argument against two responses put forth by Declan Smithies and David Christensen. Against Smithies’ response, I argue that it leads to irrational self-ascriptions of epistemic luck, and that it obscures the distinction between propositional and doxastic justification. Against Christensen’s response, I argue that it clashes with one of two attractive deontic principles, and that it is extensionally inadequate. Taken together, these criticisms will suggest that the connection between logic and rationality cannot be what it is standardly taken to be—ideal rationality does not require logical omniscience.
