Doxastic planning and epistemic internalism

In the following I discuss the debate between epistemological internalists and externalists from an unfamiliar meta-epistemological perspective. In doing so, I focus on the question of whether rationality is best captured in externalist or internalist terms. Using a conception of epistemic judgments as “doxastic plans,” I characterize one important subspecies of judgments about epistemic rationality—focusing on the distinctive rational/functional role these judgments play in regulating how we form beliefs. Then I show why any judgment that plays this role should be expected to behave the manner internalists predict. In this way, I argue, we can explain why our basic toolbox for epistemic evaluation includes an internalist conception of rationality.     

Global Constraints on Imprecise Credences: Solving Reflection Violations,Belief Inertia,and Other Puzzles

The move to imprecise credence models leaves many formal norms of rationality surprisingly intact, as rational constraints on precise credences are often reinterpreted as constraints on individual elements of a rational agent’s representor. However, constraints on imprecise credences needn’t take this form. Whether an imprecise agent is rational might just as easily depend on global features of her representor. This paper is an extended investigation of global rules of rationality. I begin by distinguishing and defining multiple notions of globalness. Then I use these notions to solve several problems faced by fans of imprecise credences. On behalf of fans of imprecise credences, I respond to the problem of belief inertia, according to which certain imprecise agents are unable to engage in inductive learning. In addition, I answer the objection that that imprecise agents are doomed to violate the rational principle of Reflection.     

Wittgenstein,Quasi-fideism,and Scepticism

In the discussion of certainties, or ‘hinges’, in Wittgenstein’s On Certainty some of the examples that Wittgenstein uses are religious ones. He remarks on how a child might be raised so that they ‘swallow down’ belief in God (§107) and in discussing the role of persuasion in disagreements he asks us to think of the case of missionaries converting natives (§612). In the past decade Duncan Pritchard has made a case for an account of the rationality of religious belief inspired by On Certainty which he calls ‘quasi-fideism’. Pritchard argues that religious beliefs are just like ordinary non-religious beliefs in presupposing fundamental arational commitments. However, Modesto Gómez-Alonso has recently argued that there are significant differences between the kinds of ‘hinges’ discussed in Wittgenstein’s On Certainty and religious beliefs such that we should expect an account of rationality in religion to be quite different to the account of rational practices and their foundations that we find in Wittgenstein’s work. Fundamental religious commitments are, as Wittgenstein said, in the foreground of the religious believer’s life whereas hinge commitments are said to be in the background. People are passionately committed to their religious beliefs but it is not at all clear that people are passionately committed to hinges such as that ‘I have two hands’. I argue here that although there are differences between religious beliefs and many of the hinge-commitments discussed in On Certainty religious beliefs are nonetheless hinge-like. Gómez-Alonso’s criticisms of Pritchard mischaracterise his views and something like Pritchard’s quasi-fideism is the correct account of the rationality of religious belief.

     

The Decision-Theoretic Lockean Thesis

Abstract

Certain philosophers maintain that there is a ‘constitutive threshold for belief’: to believe that p just is to have a degree of confidence that p above a certain threshold. On the basis of this view, these philosophers defend what is known as ‘the Lockean Thesis’, according to which it is rational to believe that p just in case it is rational to have a degree of confidence that p above the constitutive threshold for belief. While not directly speaking to the controversy over the Lockean Thesis, this paper defends the general idea behind it—namely, the thesis that there is some threshold such that it is rational to believe that p if and only if it is rational to have a degree of confidence greater than that threshold. This paper identifies the threshold in question—not with the alleged constitutive threshold for belief—but with what I call ‘the practical threshold for rational belief’. Roughly, the thesis defended here is that it is rational to believe that p if and only if it is rational to have a degree of confidence that p that rationalizes engaging in certain types of practical reasoning.     

Explaining Evidence Denial as Motivated Pragmatically Rational Epistemic Irrationality

This paper introduces a model for evidence denial that explains this behavior as a manifestation of rationality, and it is based on the contention that social values (measurable as utilities) often underwrite these sorts of responses. Moreover, it contends that the value associated with group membership in particular can override epistemic reason when the expected utility of a belief or belief system is great. It is also true, however, that it appears to be the case that it is still possible for such unreasonable believers to reverse this sort of dogmatism and to change their beliefs in a way that is epistemically rational. The conjecture made here is that we should expect this to happen only when the expected utility of the beliefs in question dips below a threshold where the utility value of continued dogmatism and the associated group membership is no longer sufficient to motivate defusing the counterevidence that tells against such epistemically irrational beliefs.     

Instrumental rationality,symmetry and scope

Instrumental rationality prohibits one from being in the following state: intending to pass a test, not intending to study, and believing one must intend to study if one is to pass. One could escape from this incoherent state in three ways: by intending to study, by not intending to pass, or by giving up one’s instrumental belief. However, not all of these ways of proceeding seem equally rational: giving up one’s instrumental belief seems less rational than giving up an end, which itself seems less rational than intending the means. I consider whether, as some philosophers allege, these “asymmetries” pose a problem for the wide-scope formulation of instrumental rationality. I argue that they do not. I also present an argument in favor of the wide-scope formulation. The arguments employed here in defense of the wide-scope formulation of instrumental rationality can also be employed in defense of the wide-scope formulations of other rational requirements.     

WHY IS THE HISTORY OF PHILOSOPHY WORTH OUR STUDY?

Abstract: Assume for the sake of argument that doing philosophy is intrinsically valuable, where “doing philosophy” refers to the practice of forging arguments for and against the truth of theses in the domains of metaphysics, epistemology, ethics, and so on. The practice of the history of philosophy is devoted instead to discovering arguments for and against the truth of “authorial” propositions, that is, propositions that state the belief of some historical figure about a philosophical proposition. I explore arguments for thinking that doing history of philosophy is valuable—specifically, valuable in such a way that its value does not reduce to the value of doing philosophy. Most such arguments proffered by historians of philosophy fail, as I show. I then offer a proposal about what makes doing history of philosophy uniquely valuable, but it is one that many historians will not find agreeable.     

An Accuracy Based Approach to Higher Order Evidence

The aim of this paper is to apply the accuracy based approach to epistemology to the case of higher order evidence: evidence that bears on the rationality of one's beliefs. I proceed in two stages. First, I show that the accuracy based framework that is standardly used to motivate rational requirements supports steadfastness—a position according to which higher order evidence should have no impact on one's doxastic attitudes towards first order propositions. The argument for this will require a generalization of an important result by Greaves and Wallace for the claim that conditionalization maximizes expected accuracy. The generalization I provide will, among other things, allow us to apply the result to cases of self‐locating evidence. In the second stage, I develop an alternative framework. Very roughly, what distinguishes the traditional approach from the alternative one is that, on the traditional picture, we're interested in evaluating the expected accuracy of conforming to an update procedure. On the alternative picture that I develop, instead of considering how good an update procedure is as a plan to conform to, we consider how good it is as a plan to make. I show how, given the use of strictly proper scoring rules, the alternative picture vindicates calibrationism: a view according to which higher order evidence should have a significant impact on our beliefs. I conclude with some thoughts about why higher order evidence poses a serious challenge for standard ways of thinking about rationality.     

Preface Writers are Consistent

The preface paradox does not show that it can be rational to have inconsistent beliefs, because preface writers do not have inconsistent beliefs. I argue, first, that a fully satisfactory solution to the preface paradox would have it that the preface writer's beliefs are consistent. The case here is on basic intuitive grounds, not the consequence of a theory of rationality or of belief. Second, I point out that there is an independently motivated theory of belief – sensitivism – which allows such a solution. I sketch a sensitivist account of the preface writer's (consistent) doxastic state.     

The Virtue of Practical Rationality

Practical rationality is best regarded as a virtue: an excellence in the exercise of one's cognitive capacities in one's practical endeavors. The author develops this idea so as to yield a Humean conception of practical rationality. Nevertheless, one of the crucial features of the approach is not distinctively Humean and sets it apart from the most familiar neo-Humean approaches: an agent's practical rationality has to do with the presence and form of his cognitive activity, as well as with how it engages his emotional and motivational states, rather than with the impact that his actions have on his utility or with how his actions relate to his expected utility. The approach also contrasts with full-information accounts of rationality. The paper ends with a discussion of our interest in operating with the conception of practical rationality that emerges from this approach, even if it is so demanding that it would be humanly impossible to be perfectly practically rational.     

Strategic behavior and counterfactuals

The difficulty of defining rational behavior in game situations is that the players' strategies will depend on their expectations about other players' strategies. These expectations are beliefs the players come to the game with. Game theorists assume these beliefs to be rational in the very special sense of beingobjectively correct but no explanation is offered of the mechanism generating this property of the belief system. In many interesting cases, however, such a rationality requirement is not enough to guarantee that an equilibrium will be attained. In particular, I analyze the case of multiple equilibria, since in this case there exists a whole set of rational beliefs, so that no player can ever be certain that the others believe he has certain beliefs. In this case it becomes necessary to explicitly model the process of belief formation. This model attributes to the players a theory of counterfactuals which they use in restricting the set of possible equilibria. If it were possible to attribute to the players the same theory of counterfactuals, then the players' beliefs would eventually converge.I wish to thank Michael Bacharach, In-Koo Cho, William Harper, Aanund Hylland, Isaac Levi, Wolfgang Spohn, Tommy Tan and two anonymous referees for many useful comments and suggestions.

Self‐deception and pragmatic encroachment: A dilemma for epistemic rationality

Self‐deception is typically considered epistemically irrational, for it involves holding certain doxastic attitudes against strong counter‐evidence. Pragmatic encroachment about epistemic rationality says that whether it is epistemically rational to believe, withhold belief or disbelieve something can depend on perceived practical factors of one's situation. In this paper I argue that some cases of self‐deception satisfy what pragmatic encroachment considers sufficient conditions for epistemic rationality. As a result, we face the following dilemma: either we revise the received view about self‐deception or we deny pragmatic encroachment on epistemic rationality. I suggest that the dilemma can be solved if we pay close attention to the distinction between ideal and bounded rationality. I argue that the problematic cases fail to meet standards of ideal rationality but exemplify bounded rationality. The solution preserves pragmatic encroachment on bounded rationality, but denies it on ideal rationality.     

Social epistemology and the aim(s) of education

In Knowledge in a Social World (1999) Alvin Goldman has defended a ‘veritistic’ or truth-oriented, monistic account of the aim of education. In particular, he argued that the inculcation of true belief constitutes the ultimate goal of education, with other educational activities having only instrumental value insofar as they aid in this goal. In contrast, Harvey Siegel has defended a pluralistic alternative, on which the critical capacity for sustaining rational belief represents an independent, non-instrumental epistemic end of education. I argue that while some of Siegel's objections represent challenges to the sufficiency of Goldman's veritistic model, his alternative account fails to recognise the necessity of truth as an educational goal. This therefore commits Siegel to an unsatisfying pluralism regarding the ideal aim of education. Crucially, this disagreement hinges on two very different ways of understanding the nature of rationality: as instrumental or as epistemic. On Goldman's instrumentalist view, rationality merely involves the ordering of one's means to the end of true belief. However, Kelly (2003) has raised significant counterexamples against the instrumentalist view, and I adapt these to the case of the epistemic ends of education. I thus defend a non-pluralistic account of the ultimate end of education as involving knowledge in the ‘strong’ sense. This, I argue, overcomes the objections raised against Goldman and Siegel's accounts, and better accords with the notion of an ideal characterisation of the aim of education.     

Rationality and reflection

Christine Korsgaard claims that an agent is less than fully rational if she allows some attitude to inform her deliberation even though she cannot justify doing so. I argue that there is a middle way, which Korsgaard misses, between the claim that our attitudes neither need nor admit of rational assessment, on the one hand, and Korsgaard's claim that the attitudes which inform our deliberation always require justification, on the other: an agent needs reasons to opt out of her concerns – not reasons to opt into them or to stay in. As long as an agent has no good reason to abandon some concern of hers, she is reasonable to harbour it, and to allow it to inform her view of what reasons she has. A rational agent must therefore have the capacity to form higher-order attitudes toward her concerns; but rationality only requires that she exercise that capacity when she has some good reason to do so.     

Credulism

Conclusion The credulity principle approach to the issue of the rationality of religious belief is a clear advance over the proof approach. For the proof approach, in the end, is simply too wedded to an infallibilist conception of rational belief; and initially, at least, the credulity principle approach seems to avoid this conception. In the end, however, it affirms that same viewpoint; for if it does not embody an infallibilist conception of epistemic principles, its critical property of intersubjectivity is beyond defense. Thus, in recognizing the inadequacy of infallibilist conceptions of rationality, we can see the inadequacy of both the proof approach and the credulity principle approach to the existence of God. It is simply false that the experiences of others is efficacious in conferring rationality on our beliefs.But if neither of these approaches is adequate, how is one to approach the issue of the rationality of religious belief? The subjective nature of rational belief provides the answer - if one wishes to argue that God exists, one will have to provide as many arguments as there are divergent sets of acceptable epistemic principles. There still is a place for such arguments; but only given the assumption that we share views about what sorts of inferences are proper, or that other arguments can be constructed for the superiority of certain epistemic principles. The view that must be given up, however, is that the discussions philosophers have of these issues need bear any relation to whether or not the normal religious believer has a reasonable belief or not - he does not need there to be a good philosophical argument that God exists in order to reasonably believe that God exists. Nor is any non-believer necessarily irrational just because there is such a good argument.Thus, once the nature of rational belief is properly appreciated, it appears that the question of the rationality of religious belief is not a central question any longer. Whether such beliefs are rational is a quite subjective question not capable of being answered by any sort of universal generalization about all religious believers and/or non-believers.     

To Believe in Belief

Summary  Take the following version of scientific realism: we have good reason to believe that (some of the) current scientific theories tell us something specific about the underlying, i.e. unobservable, structures of the world, for instance that there are electrons with a certain electric charge, or that there are viruses that cause certain diseases. Popper, the rationalist, would not have adhered to the proposed formulation of scientific realism in terms of the rationality of existential beliefs concerning unobservables. Popper did not believe in belief. According to Van Fraassen, the empiricist, one may yet have a rational existential belief concerning unobservables, given a liberal notion of rationality of belief. In this paper I will investigate to what extent a reassessment of both Popper’s rejection of the rationality of belief and Van Fraassen’s reformulation of the rationality of belief, points towards a new and pragmatist dissolution of the ‘problem of scientific realism’.     

Stop Making Sense? On a Puzzle about Rationality

In this paper, I present a puzzle about epistemic rationality. It seems plausible that it should be rational to believe a proposition if you have sufficient evidential support for it. It seems plausible that it rationality requires you to conform to the categorical requirements of rationality. It also seems plausible that our first‐order attitudes ought to mesh with our higher‐order attitudes. It seems unfortunate that we cannot accept all three claims about rationality. I will present three ways of trying to resolve this tension and argue that the best way to do this is to reject the idea that strong evidential support is the stuff rationality is made of. In the course of doing this, I shall argue that there is a special class of propositions about the requirements of rationality that we cannot make rational mistakes about and explain how this can be.     

Coherence as an ideal of rationality

Probabilistic coherence is not an absolute requirement of rationality; nevertheless, it is an ideal of rationality with substantive normative import. An idealized rational agent who avoided making implicit logical errors in forming his preferences would be coherent. In response to the challenge, recently made by epistemologists such as Foley and Plantinga, that appeals to ideal rationality render probabilism either irrelevant or implausible, I argue that idealized requirements can be normatively relevant even when the ideals are unattainable, so long as they define a structure that links imperfect and perfect rationality in a way that enables us to make sense of the notion of better approximations to the ideal. I then analyze the notion of approximation to the ideal of coherence by developing a generalized theory of belief functions that allows for incoherence, and showing how such belief functions can be ordered with regard to greater or lesser coherence.Many people influenced the present version of this essay. Ban van Frassen, Richard Jeffrey, David Lewis, Mike Thau, and Alan Hájek provided extensive and invaluable written comments on the entire essay. Mark van Roojen provided helpful comments on Sections 3 and 4. Mike Than and John Barker provided essential aid when I was formulating the proofs in section 6. Finally, I am grateful for valuable discussion of the essay with Ned Hall, Fiona Cowie, Jim Woodward, David Hilbert, and Frank Arntzenius.     

The Rationality of Belief and Some Other Propositional Attitudes

In this paper, I explore the question of whether the expectedconsequences of holding a belief can affect the rationality ofdoing so. Special attention is given to various ways in whichone might attempt to exert some measure of control over whatone believes and the normative status of the beliefs thatresult from the successful execution of such projects. I arguethat the lessons which emerge from thinking about the case ofbelief have important implications for the way we should thinkabout the rationality of a number of other propositional attitudes,such as regret, desire, and fear. Finally,I suggest that a lack of clarity with respect to the relevant issueshas given rise to a number of rather serious philosophical mistakes.     

Belief, faith, and acceptance

Belief is a central focus of inquiry in the philosophy of religion and indeed in the field of religion itself. No one conception of belief is central in all these cases, and sometimes the term ‘belief’ is used where ‘faith’ or ‘acceptance’ would better express what is intended. This paper sketches the major concepts in the philosophy of religion that are expressed by these three terms. In doing so, it distinguishes propositional belief (belief that) from both objectual belief (believing something to have a property) and, more importantly, belief in (a trusting attitude that is illustrated by at least many paradigm cases of belief in God). Faith is shown to have a similar complexity, and even propositional faith divides into importantly different categories. Acceptance differs from both belief and faith in that at least one kind of acceptance is behavioral in a way neither of the other two elements is. Acceptance of a proposition, it is argued, does not entail believing it, nor does believing entail acceptance in any distinctive sense of the latter term. In characterizing these three notions (and related ones), the paper provides some basic materials important both for understanding a person’s religious position and for appraising its rationality. The nature of religious faith and some of the conditions for its rationality, including some deriving from elements of an ethics of belief, are explored in some detail.
