It is a platitude that when we reason, we often take things for granted, sometimes even justifiably so. The chemist might reason from the fact that a substance turns litmus paper red to that substance being an acid. In so doing, they take for granted, reasonably enough, that this test for acidity is valid. We ordinarily reason from things looking a certain way to their being that way. We take for granted, reasonably enough, that things are as they look Although (...) it is a platitude that we often take things for granted when we reason—whether justifiably or not—one might think that we do not have to. In fact, it is a natural expectation that were we not pressed by time, lack of energy or focus, we could always in principle make explicit in the form of premises every single presupposition we make in the course of our reasoning. In other words, it is natural to expect it to be true that presuppositionless reasoning is possible. In this essay, I argue that it is false: presuppositionless reasoning is impossible. Indeed, I think this is one of the lessons of a long-standing paradox about inference and reasoning known as Lewis Carroll’s (1985) regress of the premises. Many philosophers agree that Carroll’s regress teaches us something foundational about reasoning. I part ways about what it is that it teaches us. What it teaches us is that the structure of reasoning is constitutively presuppositional. (shrink)

Boris Kment takes a new approach to the study of modality that emphasises the origin of modal notions in everyday thought. He argues that the concepts of necessity and possibility originate in counterfactual reasoning, which allows us to investigate explanatory connections. Contrary to accepted views, explanation is more fundamental than modality.

Philosophers have often noted a contrast between practical and theoretical reasons when it comes to cases involving equally balanced reasons. When there are strong practical reasons for A-ing, and equally strong practical reasons for some incompatible option, B-ing, the agent is permitted to make an arbitrary choice between them, having sufficient reason to A and sufficient reason to B. But when there is strong evidence for P and equally strong evidence for ~ P, one isn’t permitted to simply believe one (...) or the other. Instead, one must withhold belief, neither believing that P nor believing that ~ P. This paper examines what explains this contrast, focusing in particular on a proposal recently developed by Mark Schroeder across several papers. Schroeder aims to explain the contrast by an appeal to non-evidential, epistemic reasons against belief. But, I argue, it’s not clear exactly what those reasons are, nor how those reasons are to be weighed against evidential reasons. Despite these challenges, I argue that there are grounds for optimism that the contrast can be explained within the broad framework Schroeder provides, and I aim to provide resources to meet the aforementioned challenges.

In this paper, we argue for a particular informative and unified analysis of normative reasons. According to this analysis, a fact F is a reason to act in a certain way just in case it is evidence that one ought to act in that way. Similarly, F is a reason to believe a certain proposition just in case it is evidence for the truth of this proposition. Putting the relatively uncontroversial claim about reasons for belief to one side, we present (...) several arguments in favor of our analysis of reasons for action. We then turn to consider a series of objections to the analysis. We conclude that there are good reasons to accept the analysis and that the objections do not succeed. (shrink)

Many philosophers have been attracted to the view that reasons are premises of good reasoning – that reasons to φ are premises of good reasoning towards φ-ing. However, while this reasoning view is indeed attractive, it faces a problem accommodating outweighed reasons. In this article, I argue that the standard solution to this problem is unsuccessful and propose an alternative, which draws on the idea that good patterns of reasoning can be defeasible. I conclude by drawing (...) out implications for the debate over pragmatic reasons for belief and other attitudes and for one influential form of reductionism about the normative. (shrink)

This is a discussion of the state of discussion on pragmatic reasons for belief.

This paper examines precursors and consequents of perceived relevance of a proposition A for a proposition C. In Experiment 1, we test Spohn's assumption that ∆P = P − P is a good predictor of ratings of perceived relevance and reason relations, and we examine whether it is a better predictor than the difference measure − P). In Experiment 2, we examine the effects of relevance on probabilistic coherence in Cruz, Baratgin, Oaksford, and Over's uncertain “and-to-if” inferences. The results suggest (...) that ∆P predicts perceived relevance and reason relations better than the difference measure and that participants are either less probabilistically coherent in “and-to-if” inferences than initially assumed or that they do not follow P = P. Results are discussed in light of recent results suggesting that the Equation may not hold under conditions of irrelevance or negative relevance. (shrink)

According to a common conception of legal proof, satisfying a legal burden requires establishing a claim to a numerical threshold. Beyond reasonable doubt, for example, is often glossed as 90% or 95% likelihood given the evidence. Preponderance of evidence is interpreted as meaning at least 50% likelihood given the evidence. In light of problems with the common conception, I propose a new ‘relevant alternatives’ framework for legal standards of proof. Relevant alternative accounts of knowledge state that a person knows a (...) proposition when their evidence rules out all relevant error possibilities. I adapt this framework to model three legal standards of proof—the preponderance of evidence, clear and convincing evidence, and beyond reasonable doubt standards. I describe virtues of this framework. I argue that, by eschewing numerical thresholds, the relevant alternatives framework avoids problems inherent to rival models. I conclude by articulating aspects of legal normativity and practice illuminated by the relevant alternatives framework. (shrink)

I defend the view that a reason for someone to do something is just a reason why she ought to do it. This simple view has been thought incompatible with the existence of reasons to do things that we may refrain from doing or even ought not to do. For it is widely assumed that there are reasons why we ought to do something only if we ought to do it. I present several counterexamples to this principle and reject some (...) ways of understanding "ought" so that the principle is compatible with my examples. I conclude with a hypothesis for when and why the principle should be expected to fail. (shrink)

The philosophical literature on reasoning is dominated by the assumption that reasoning is essentially a matter of following rules. This paper challenges this view, by arguing that it misrepresents the nature of reasoning as a personal level activity. Reasoning must reflect the reasoner’s take on her evidence. The rule-following model seems ill-suited to accommodate this fact. Accordingly, this paper suggests replacing the rule-following model with a different, semantic approach to reasoning.

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If not, when do we find commensurability and comparability unavailable? What are the moral and legal implications? In this book, philosophers address these questions.

This paper investigates two puzzles in practical reason and proposes a solution to them. First, sometimes, when we are practically certain that neither of two alternatives is better than or as good as the other with respect to what matters in the choice between them, it nevertheless seems perfectly rational to continue to deliberate, and sometimes the result of that deliberation is a conclusion that one alternative is better, where there is no error in one’s previous judgment. Second, there are (...) striking differences between rational agents – some rational agents have most reason to pursue careers on Wall Street while others have most reason to take up a career in teaching, or scuba diving, or working for political causes. These differences aren’t plausibly explained by ‘passive’ facts about our psychology or their causal interaction with our environment; instead, these facts seem in some sense to ‘express who we are’. But what is this sense? These puzzles disappear if we adopt a novel view about the source of the normativity of reasons – some reasons are given to us and others are reasons in virtue of an act of will. We make certain considerations reasons through an act of will and thus sometimes make it true through an act of agency that we have most reason to do one thing rather than another. (shrink)

In this paper, I develop a theory of how claims about an agent’s normative reasons are sensitive to the epistemic circumstances of this agent, which preserves the plausible ideas that reasons are facts and that reasons can be discovered in deliberation and disclosed in advice. I argue that a plausible theory of this kind must take into account the difference between synchronic and diachronic reasons, i.e. reasons for acting immediately and reasons for acting at some later point in time. I (...) provide a general account of the relation between synchronic and diachronic reasons, demonstrate its implications for the evidence-sensitivity of reasons and finally present and defend an argument for my view.

Bernard Williams's motivational reasons-internalism fails to capture our first-order reasons judgements, while Derek Parfit's nonnaturalistic reasons-externalism cannot explain the nature or normative authority of reasons. This paper offers an intermediary view, reformulating scepticism about external reasons as the claim not that they don't exist but rather that they don't matter. The end-relational theory of normative reasons is proposed, according to which a reason for an action is a fact that explains why the action would be good relative to some end, (...) where the relevant end for any ascription of reasons is determined by the speaker's conversational context. Because these ends need not be the agent's ends, Williams is wrong to reject the existence of external reasons. But contra Parfit, a reason for action is only important for an agent if it is motivationally internal to that agent. (shrink)

There is a surprising disconnect between formal rational choice theory and philosophical work on reasons. The one is silent on the role of reasons in rational choices, the other rarely engages with the formal models of decision problems used by social scientists. To bridge this gap, we propose a new, reason-based theory of rational choice. At its core is an account of preference formation, according to which an agent’s preferences are determined by his or her motivating reasons, together with a (...) ‘weighing relation’ between different combinations of reasons. By explaining how someone’s preferences may vary with changes in his or her motivating reasons, our theory illuminates the relationship between deliberation about reasons and rational choices. Although primarily positive, the theory can also help us think about how those preferences and choices ought to respond to normative reasons. (shrink)

In the late summer of 1998, the authors, a cognitive scientist and a logician, started talking about the relevance of modern mathematical logic to the study of human reasoning, and we have been talking ever since. This book is an interim report of that conversation. It argues that results such as those on the Wason selection task, purportedly showing the irrelevance of formal logic to actual human reasoning, have been widely misinterpreted, mainly because the picture of logic current (...) in psychology and cognitive science is completely mistaken. We aim to give the reader a more accurate picture of mathematical logic and, in doing so, hope to show that logic, properly conceived, is still a very helpful tool in cognitive science. The main thrust of the book is therefore constructive. We give a number of examples in which logical theorizing helps in understanding and modeling observed behavior in reasoning tasks, deviations of that behavior in a psychiatric disorder (autism), and even the roots of that behavior in the evolution of the brain.

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main contenders, critically (...) compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

There is an intuitive difference in how we think about pluralism and attitudinal diversity in epistemological contexts versus political contexts. In an epistemological context, it seems problematically arbitrary to hold a particular belief on some issue, while also thinking it perfectly reasonable to hold a totally different belief on the same issue given the same evidence. By contrast, though, it doesn’t seem problematically arbitrary to have a particular set of political commitments, while at the same time thinking it perfectly reasonable (...) for someone in a similar position have a totally different set of political commitments. This chapter examines three explanatory theses that might be used to make sense of this difference: (1) that practical commitments are desire dependent in a way that beliefs are not; (2) that there are reasons to be resolute in practical commitments, but not in beliefs; and (3) that compromise in the face of practical political disagreement doesn’t mitigate controversy, whereas compromise in the face of disagreement about mere beliefs does mitigate controversy.

Regress arguments have convinced many that reasoning cannot require beliefs about what follows from what. In this paper I argue that this is a mistake. Regress arguments rest on dubious (although deeply entrenched) assumptions about the nature of reasoning — most prominently, the assumption that believing p by reasoning is simply a matter of having a belief in p with the right causal ancestry. I propose an alternative account, according to which beliefs about what follows from what (...) play a constitutive role in reasoning. (shrink)

This paper explores various subtleties in our ordinary thought and talk about normative reasons—subtleties which, if taken seriously, have various upshots, both substantive and methodological. I focus on two subtleties in particular. The first concerns the use of reason (in its normative sense) as both a count noun and as a mass noun, and the second concerns the context-sensitivity of normative reasons-claims. The more carefully we look at the language of reasons, I argue, the clearer its limitations and liabilities become. (...) The cumulative upshot is that although talk of reasons is intelligible and useful for the purposes of communication, we should be wary of placing much weight on it when engaging in substantive normative inquiry. By way of illustration, I consider some potential pitfalls of taking our talk of reasons too seriously, explaining how careful attention to the language of reasons undermines the main argument for moral particularism, Mark Schroeder’s recent defense of Humeanism about practical reasons, and the “reasons-first” program in metanormativity.

This paper is a response to two sets of published criticisms of the 'Reasons as Evidence’ thesis concerning normative reasons, proposed and defended in earlier papers. According to this thesis, a fact is a normative reason for an agent to Φ just in case this fact is evidence that this agent ought to Φ. John Broome and John Brunero have presented a number of challenging criticisms of this thesis which focus, for the most part, on problems that it appears to (...) confront when it comes to the topic of the weighing of reasons. Our paper responds to all of the criticisms that these critics have provided, shedding fresh light on this interesting topic in the process. (shrink)

A long debate in aesthetics concerns the reasoned nature of criticism. The main questions in the debate are whether criticism is based on (normative) reasons, whether critics communicate reasons for their audience’s responses, and if so, how to understand these critical reasons. I argue that a great obstacle to making any progress in this debate is the deeply engrained assumption, shared by all sides of the debate, that reasons can only be either theoretical reasons (i.e., those that explain what to (...) believe or what propositions are true) or practical reasons (i.e., those that explain what is to be done or what actions are good/required/called for/otherwise worthy of doing). My aims are (1) to put pressure on this assumption that, if there are critical reasons, they must be either theoretical or practical (the EITHER/OR assumption), and (2) to suggest that, if there are critical reasons, the most central among them are neither theoretical nor practical (NEITHER/NOR). (shrink)

Many philosophers accept a response constraint on normative reasons: that p is a reason for you to φ only if you are able to φ for the reason that p. This constraint offers a natural way to cash out the familiar and intuitive thought that reasons must be able to guide us, and has been put to work as a premise in a range of influential arguments in ethics and epistemology. However, the constraint requires interpretation and faces putative counter-examples due (...) to Julia Markovits, Mark Schroeder, and others. This paper develops and motivates an interpretation of the response constraint that avoids the putative counter-examples. (shrink)

The fact that someone is generous is a reason to admire them. The fact that someone will pay you to admire them is also a reason to admire them. But there is a difference in kind between these two reasons: the former seems to be the ‘right’ kind of reason to admire, whereas the latter seems to be the ‘wrong’ kind of reason to admire. The Wrong Kind of Reasons Problem is the problem of explaining the difference between the ‘right’ (...) and the ‘wrong’ kind of reasons wherever it appears. In this article I argue that two recent proposals for solving the Wrong Kind of Reasons Problem do not work. I then offer an alternative solution that provides a unified, systematic explanation of the difference between the two kinds of reasons. (shrink)

What does the aesthetic ask of us? What claims do the aesthetic features of the objects and events in our environment make on us? My answer in this paper is: that depends. Aesthetic reasons can only justify feelings – they cannot demand them. A corollary of this is that there are no aesthetic obligations to feel, only permissions. However, I argue, aesthetic reasons can demand actions – they do not merely justify them. A corollary of this is that there are (...) aesthetic obligations to act, not only permissions. So, I conclude, the aesthetic asks little of us as patients and much of as agents. (shrink)

In this paper, I defend a new theory of normative reasons called reasons as good bases, according to which a normative reason to φ is something that is a good basis for φing. The idea is that the grounds on which we do things—bases—can be better or worse as things of their kind, and a normative reason—a good reason—is something that is just a good instance of such a ground. After introducing RGB, I clarify what it is to be a (...) good basis, and argue that RGB has various attractive features: it has intuitive implications, makes good sense of the weights of reasons, and attractively explains the relationship between normative reasons and motivating reasons. I then briefly defend the view from objections and compare it to rivals. Finally, I sketch two possible implications of RGB: some kind of constitutivism, according to which the norms that govern us are explained by the nature of agency, and second, the claim that agents who do things for reasons generally do them for good reasons.

Many hold that theoretical reasoning aims at truth. In this paper, I ask what it is for reasoning to be thus aim-directed. Standard answers to this question explain reasoning’s aim-directedness in terms of intentions, dispositions, or rule-following. I argue that, while these views contain important insights, they are not satisfactory. As an alternative, I introduce and defend a novel account: reasoning aims at truth in virtue of being the exercise of a distinctive kind of cognitive power, (...) one that, unlike ordinary dispositions, is capable of fully explaining its own exercises. I argue that this account is able to avoid the difficulties plaguing standard accounts of the relevant sort of mental teleology. (shrink)

Public reason as a political ideal aims to reconcile reasonable disagreement; however, is public reason itself the object of reasonable disagreement? Jonathan Quong, David Estlund, Andrew Lister, and some other philosophers maintain that public reason is beyond reasonable disagreement. I argue this view is untenable. In addition, I consider briefly whether or not two main versions of the public reason principle, namely, the consensus version and the convergence version, need to satisfy their own requirements. My discussion has several important implications (...) for the debate on public reason. (shrink)

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

Ethicists increasingly reject the scale as a useful metaphor for weighing reasons. Yet they generally retain the metaphor of a reason’s weight. This combination is incoherent. The metaphor of weight entails a very specific scale-based model of weighing reasons, Dual Scale. Justin Snedegar worries that scale-based models of weighing reasons can’t properly weigh reasons against an option. I show that there are, in fact, two different reasons for/against distinctions, and I provide an account of the relationship between the various kinds (...) of reason for and against. With this account in hand, we’ll see that Dual Scale has no problem weighing any kind of reason against. (shrink)

I argue that Davidson's conception of motivating reasons as belief-desire pairs suggests a model of normative reasons for action that is superior to the orthodox conception according to which normative reasons are propositions, facts, or the truth-makers of such facts.

This chapter argues that there is a particular kind of ‘internal’ commitment typically made in the context of romantic love relationships that has striking meta-normative implications for how we understand the role of the will in practical normativity. Internal commitments cannot plausibly explain the reasons we have in committed relationships on the usual model—as triggering reasons that are already there, in the way that making a promise triggers a reason via a pre-existing norm of the form ‘If you make a (...) promise to x, then you have a reason to x’. Instead, internal commitments are that in virtue of which one has the special reasons of committed relationships; they are the grounds of such reasons. In this way, the will is a source of practical normativity. (shrink)

It is commonly held that p is a reason for A to ϕ only if p explains why A ought to ϕ. I argue that this view must be rejected because there are reasons for A to ϕ that would be redundant in any ex...

Reasons are considerations that figure in sound reasoning. This is considered by many philosophers to be little more than a platitude. I argue that it actually has surprising and far-reaching metanormative implications. The view that reasons are linked to sound reasoning seems platitudinous only because we tend to assume that soundness is a normative property, in which case the view merely relates one normative phenomenon (reasons) to another (soundness). I argue that soundness is also a descriptive phenomenon, one (...) we can pick out with purely descriptive terms, and that the connection between normative reasons and sound reasoning therefore provides the basis for a reductive account of reasons. Like all proposed reductions, this one must confront some version of G. E. Moore’s open question argument. I argue that a reductive view rooted in the idea that reasons figure in sound reasoning is well-equipped to meet the open question challenge head on. (shrink)

The two main theories of perceptual reasons in contemporary epistemology can be called Phenomenalism and Factualism. According to Phenomenalism, perceptual reasons are facts about experiences conceived of as phenomenal states, i.e., states individuated by phenomenal character, by what it’s like to be in them. According to Factualism, perceptual reasons are instead facts about the external objects perceived. The main problem with Factualism is that it struggles with bad cases: cases where perceived objects are not what they appear or where there (...) is no perceived object at all. The main problem with Phenomenalism is that it struggles with good cases: cases where everything is perfectly normal and the external object is correctly perceived, so that one’s perceptual beliefs are knowledge. In this paper we show that there is a theory of perceptual reasons that avoids the problems for Factualism and Phenomenalism. We call this view Propositionalism. We use ‘proposition’ broadly to mean the entities that are contents of beliefs and other doxastic attitudes. The key to finding a middle ground between Phenomenalism and Factualism, we claim, is to allow our reasons to be false in bad cases. Despite being false, they are about the external world, not our phenomenal states. (shrink)

A promising but underexplored view about normative reasons is contrastivism, which holds that considerations are fundamentally reasons for things only relative to sets of alternatives. Contrastivism gains an advantage over non-contrastive theories by holding that reasons relative to different sets of alternatives can be independent of one another. But this feature also raises a serious problem: we need some way of constraining this independence. I develop a version of contrastivism that provides the needed constraints, and that is independently motivated by (...) the widespread idea that reasons involve the promotion of various kinds of objectives. (shrink)

In a number of recent philosophical debates, it has become common to distinguish between two kinds of normative reasons, often called the right kind of reasons (henceforth: RKR) and the wrong kind of reasons (henceforth: WKR). The distinction was first introduced in discussions of the so-called buck-passing account of value, which aims to analyze value properties in terms of reasons for pro-attitudes and has been argued to face the wrong kind of reasons problem. But nowadays it also gets applied in (...) other philosophical contexts and to reasons for other responses than pro-attitudes, for example in recent debates about evidentialism and pragmatism about reasons for belief. While there seems to be wide agreement that there is a general and uniform distinction that applies to reasons for different responses, there is little agreement about the scope, relevance and nature of this distinction. Our aim in this article is to shed some light on this issue by surveying the RKR/WKR distinction as it has been drawn with respect to different responses, and by examining how it can be understood as a uniform distinction across different contexts. We start by considering reasons for pro-attitudes and emotions in the context of the buck-passing account of value (§1). Subsequently we address the distinction that philosophers have drawn with respect to reasons for other attitudes, such as beliefs and intentions (§2), as well as with respect to reasons for action (§3). We discuss the similarities and differences between the ways in which philosophers have drawn the RKR/WKR distinction in these areas and offer different interpretations of the idea of a general, uniform distinction. The major upshot is that there is at least one interesting way of substantiating a general RKR/WKR distinction with respect to a broad range of attitudes as well as actions. We argue that this has important implications for the proper scope of buck-passing accounts and the status of the wrong kind of reasons problem (§4). (shrink)

Faith is a central attitude in Christian religious practice. The problem of faith and reason is the problem of reconciling religious faith with the standards for our belief-forming practices in general (‘ordinary epistemic standards’). In order to see whether and when faith can be reconciled with ordinary epistemic standards, we first need to know what faith is. This chapter examines and catalogues views of propositional faith: faith that p. It is concerned with the epistemology of such faith: what cognitive attitudes (...) does such faith require, what epistemic norms govern these attitudes, and whether Christian faith can ever adhere to them.

This chapter argues that epistemic uses of the imagination are a sui generis form of reasoning. The argument proceeds in two steps. First, there are imaginings which instantiate the epistemic structure of reasoning. Second, reasoning with imagination is not reducible to reasoning with doxastic states. Thus, the epistemic role of the imagination is that it is a distinctive way of reasoning out what follows from our prior evidence. This view has a number of important implications (...) for the epistemology of the imagination. For one thing, it clarifies the epistemic role of widely invoked “constraints” on the imagination. For another, it highlights important and underappreciated disanalogies between how perceptual experiences and imaginings justify beliefs. Ultimately, the view that we can reason with imagination offers an illuminating and theoretically fruitful framework through which to understand the epistemic structure of the imagination. (shrink)

Proponents of the reasoning view analyze normative reasons as premises of good reasoning and explain the normativity of reasons by appeal to their role as premises of good reasoning. The aim of this paper is to cast doubt on the reasoning view by providing counterexamples to the proposed analysis of reasons, counterexamples in which premises of good reasoning towards φ‐ing are not reasons to φ.

Contrastivism about reasons is the view that ‘reason’ expresses a relation with an argument place for a set of alternatives. This is in opposition to a more traditional theory on which reasons are reasons for things simpliciter. I argue that contrastivism provides a solution to a puzzle involving reason claims that explicitly employ ‘rather than’. Contrastivism solves the puzzle by allowing that some fact might be a reason for an action out of one set of alternatives without being a reason (...) for that action out of a different set of alternatives.

One leading approach to justification comes from the reliabilist tradition, which maintains that a belief is justified provided that it is reliably formed. Another comes from the ‘Reasons First’ tradition, which claims that a belief is justified provided that it is based on reasons that support it. These two approaches are typically developed in isolation from each other; this essay motivates and defends a synthesis. On the view proposed here, justification is understood in terms of an agent’s reasons for belief, (...) which are in turn analyzed along reliabilist lines: an agent's reasons for belief are the states that serve as inputs to their reliable processes. I show that this synthesis allows each tradition to profit from the other's explanatory resources. In particular, it enables reliabilists to explain epistemic defeat without abandoning their naturalistic ambitions. I go on to compare my proposed synthesis with other hybrid versions of reliabilism that have been proposed in the literature. (shrink)

The creation of guidelines has long been a popular means of conveying normative requirements in scientific and medical research. The recent case of He Jiankui, whose research flouted both widely accepted ethical standards and a set of field-specific guidelines he co-authored, raises the question of whether guidelines are an effective means of preventing misconduct. This paper advances the theory that guidelines can facilitate moral rationalization, a form of motivated reasoning. Moral rationalization in research occurs when individuals justify their actions (...) with plausible reasons that cohere with their moral standards. This allows them to act as they want while believing in their own goodness. If guidelines facilitate moral rationalization, this has implications for research ethics training and for the work of applied ethicists. Research ethics training ought to incorporate reflection on conative features of reasoning, including incentives to commit misconduct, and applied ethicists ought to be circumspect about their use of ethics guidelines. Otherwise, they are feeding the fire of rationalization with the cognitive material practitioners need to accomplish their desired ends. (shrink)

Material traces of the past are notoriously inscrutable; they rarely speak with one voice, and what they say is never unmediated. They stand as evidence only given a rich scaffolding of interpretation which is, itself, always open to challenge and revision. And yet archaeological evidence has dramatically expanded what we know of the cultural past, sometimes demonstrating a striking capacity to disrupt settled assumptions. The questions we address in Evidential Reasoning are: How are these successes realized? What gives us (...) confidence in the credibility and robustness, the trustworthiness, of the evidential claims based on archaeological data? And, what constitute best practices in building evidential claims, critically scrutinizing them and putting them to work in archaeological contexts? Rather than retreat to abstractions about how how science operates in the ideal, we approach this question by interrogating a number of close-to-the-ground case studies with the aim of teasing out the wisdom embodied in archaeological practice. The cases we consider – of fieldwork, strategies for working with old evidence, and the role of external resources – illuminate the role of various types of inferential scaffolding and bring into focus practice-grounded epistemic norms that we believe serve archaeologists better than the all-or-nothing ideals of truth and objectivity that dominate programmatic debate.

Which rules should guide our reasoning? Human reasoners often use reasoning shortcuts, called heuristics, which function well in some contexts but lack the universality of reasoning rules like deductive implication or inference to the best explanation. Does it follow that human reasoning is hopelessly irrational? I argue: no. Heuristic reasoning often represents human reasoners reaching a local rational maximum, reasoning more accurately than if they try to implement more “ideal” rules of reasoning. I (...) argue this is a genuine rational achievement. Our ideal rational advisors would advise us to reason with heuristic rules, not more complicated ideal rules. I argue we do not need a radical new account of epistemic norms to make sense of the success of heuristic reasoning. (shrink)

What is involved in weighing normative reasons against each other? One attractive answer offers us the following Simple Picture: a fact is a reason for action when it bears to an action the normative relation of counting in its favour; this relation comes in different strengths or weights; the weights of the reasons for and against an action can be summed; the reasons for performing the action are sufficient when no other action is more strongly supported, overall; the reasons are (...) decisive when it is most strongly supported; one ought to perform the action there is most reason to perform; rational deliberation is weighing reasons correctly; and acting rationally is doing what one has sufficient reasons to do. This chapter investigates various ways in which, on examination, this Simple Picture appears to require modification and refinement. It examines some of the ways in which talk of the weight of a reason may need improvement, looks more closely at the relationship between reasons and rationality, and asks whether there are ways in which a reason can be defeated which are not kinds of outweighing. The conclusion is that while in some respects the Simple Picture does need to be corrected, in others the jury is out. (shrink)

There is a long tradition in formal epistemology and in the psychology of reasoning to investigate indicative conditionals. In psychology, the propositional calculus was taken for granted to be the normative standard of reference. Experimental tasks, evaluation of the participants’ responses and psychological model building, were inspired by the semantics of the material conditional. Recent empirical work on indicative conditionals focuses on uncertainty. Consequently, the normative standard of reference has changed. I argue why neither logic nor standard probability theory (...) provide appropriate rationality norms for uncertain conditionals. I advocate coherence based probability logic as an appropriate framework for investigating uncertain conditionals. Detailed proofs of the probabilistic non-informativeness of a paradox of the material conditional illustrate the approach from a formal point of view. I survey selected data on human reasoning about uncertain conditionals which additionally support the plausibility of the approach from an empirical point of view. (shrink)

In ‘Public Reason and Prenatal Moral Status’, Jeremy Williams argues that the ideal of Rawlsian public reason commits its devotees to the radically permissive view that abortion ought to be available with little or no qualification throughout pregnancy. This is because the only political value that favours protection of the foetus for its own sake—the value of ‘respect for human life’—turns out not to be a political value at all, and so its invocation in support of considerations bearing upon the (...) permissibility of abortion is beyond public reason’s remit. Thus, it will scarcely if ever be legitimate to restrict women’s equality and bodily autonomy for the sake of the foetus, even at full term. In this paper, I argue that Williams fails to establish that Rawlsian reasonable citizens must endorse the radically permissive stance vis-à-vis abortion. Citizens can, I claim, reasonably accord the value of respect for human life weight, and indeed converge on the claim that it outweighs other salient political values, during later stages of gestation. Nevertheless, Williams’s argument gets something right in that it reveals why the value of respect for human life is inadmissible at the bar of public reason in early stages of pregnancy. But then, far from throwing Rawlsian public reason into disrepute, Williams’s argument actually provides arguably more compelling grounds than any hitherto rallied for endorsing Rawls’s much maligned claim that opposition to the duly qualified right to abortion in the first trimester of pregnancy is ‘unreasonable’.

Hearing has traditionally been regarded as the second sense--as somehow less rational and less modern than the first sense, sight. Reason and Resonance explodes this myth by reconstructing the process through which the ear came to play a central role in modern culture and rationality. For the past four hundred years, hearing has been understood as involving the sympathetic resonance between the vibrating air and various parts of the inner ear. But the emergence of resonance as the centerpiece of modern (...) aurality also coincides with the triumph of a new type of epistemology in which the absence of resonance is the very condition of thought. Our mind's relationship to the world is said to rest on distance or, as the very synonym for reason suggests, reflection. Reason and Resonance traces the genealogy of this "intimate animosity" between reason and resonance through a series of interrelated case studies involving a varied cast of otologists, philosophers, physiologists, pamphleteers, and music theorists. Among them are the seventeenth-century architect-zoologist Claude Perrault, who refuted Cartesianism in a book on sound and hearing; the Sturm und Drang poet Wilhelm Heinse and his friend the anatomist Samuel Sömmerring, who believed the ventricular fluid to be the interface between the soul and the auditory nerve; the renowned physiologist Johannes Müller, who invented the concept of "sense energies"; and Müller's most important student, Hermann von Helmholtz, author of the magisterial Sensations of Tone. Erlman also discusses key twentieth-century thinkers of aurality, including Ernst Mach; the communications engineer and proponent of the first nonresonant wave theory of hearing, Georg von Békésy; political activist and philosopher Günther Anders; and Martin Heidegger.

This paper is an opinionated guide to the literature on normative epistemic reasons. After making some distinctions in §1, I begin in §2 by discussing the ontology of normative epistemic reasons, assessing arguments for and against the view that they are mental states, and concluding that they are not mental states. In §3, I examine the distinction between normative epistemic reasons there are and normative epistemic reasons we possess. I offer a novel account of this distinction and argue that we (...) in fact ought to acknowledge a threefold distinction between objective, possessed, and apparent normative epistemic reasons. In §4, I discuss the question of which normative reasons for doxastic attitudes are the epistemic ones, evaluating reasons against a simple evidentialist answer. Finally, in §5, I look at the role of reasons in epistemology, considering challenges to viewing reasons as the building blocks of epistemic normativity and maintaining that the challenges recommend a novel bi-level epistemology rather than a marginalization of reasons in epistemology.
