According to dogmatism, one may know a proposition by inferring it from a set of evidence even if one has no independent grounds for rejecting a skeptical hypothesis compatible with one’s evidence but incompatible with one’s conclusion. Despite its intuitive attractions, many philosophers have argued that dogmatism goes wrong because they have thought that it licenses Moorean reasoning — i.e., reasoning in which one uses the conclusion of an inference as a premise in an argument against a (...) skeptical hypothesis that would undermine that very inference. In this paper I defend dogmatism against this line of thought. To begin with, I argue that the common assumption that uncontroversial Bayesian principles suffice to show that Moorean reasoning is not cogent is false: for all that Bayesianism says on the matter, Moorean reasoning might be perfectly fine. Nevertheless, Moorean reasoning does seem intuitively defective. As I argue, however, this does not provide grounds for an argument against dogmatism, because — contrary to what many philosophers have thought — dogmatism need not license Moorean reasoning. On the contrary, as I argue, dogmatism predicts that Moorean reasoning suffers from a clearly identifiable defect. (shrink)

This article addresses and resolves an epistemological puzzle that has attracted much attention in the recent literature—namely, the puzzle arising from Moorean anti-sceptical reasoning and the phenomenon of transmission failure. The paper argues that an appealing account of Moorean reasoning can be given by distinguishing carefully between two subtly different ways of thinking about justification and evidence. Once the respective distinctions are in place we have a simple and straightforward way to model both the Wrightean position (...) of transmission failure and the Moorean position of dogmatism. The approach developed in this article is, accordingly, ecumenical in that it allows us to embrace two positions that are widely considered to be incompatible. The paper further argues that the Moorean Puzzle can be resolved by noting the relevant distinctions and our insensitivity towards them: once we carefully tease apart the different senses of ‘justified’ and ‘evidence’ involved, the bewilderment caused by Moore’s anti-sceptical strategy subsides.

Offering a solution to the skeptical puzzle is a central aim of Nozick's sensitivity account of knowledge. It is well-known that this account faces serious problems. However, because of its simplicity and its explanatory power, the sensitivity principle has remained attractive and has been subject to numerous modifications, leading to a of sensitivity accounts. I will object to these accounts, arguing that sensitivity accounts of knowledge face two problems. First, they deliver a far too heterogeneous picture of higher-level beliefs about (...) the truth or falsity of one's own beliefs. Second, this problem carries over to bootstrapping and Moorean reasoning. Some beliefs formed via bootstrapping or Moorean reasoning are insensitive, but some closely related beliefs in even stronger propositions are sensitive. These heterogeneous results regarding sensitivity do not fit with our intuitions about bootstrapping and Moorean reasoning. Thus, neither Nozick's sensitivity account of knowledge nor any of its modified versions can provide the basis for an argument that bootstrapping and Moorean reasoning are flawed or for an explanation why they seem to be flawed.

In this paper, I defend Moorean Dogmatism against a novel objection raised by Adam Leite. Leite locates the defectiveness of the Moorean reasoning explicitly not in the failure of the Moorean argument to transmit warrant from its premises to its conclusion but rather in the failure of an epistemic agent to satisfy certain epistemic responsibilities that arise in the course of conscious and deliberate reasoning. I will first show that there exist cases of Moorean (...) reasoning that are not put into jeopardy by the considerations that Leite presents. Second, I will argue that certain commitments of Leite’s concerning the notion of warrant are in tension with his verdict that the Moorean reasoning is defective. (shrink)

Moore's paradox is a paradox in which certain kinds of belief or assertion, such as a belief that ?it is raining and I do not believe that it is raining?, are irrational despite involving no obvious contradiction in what is believed. But is there a parallel paradox involving other kinds of attitude, in particular desire? I argue that certain kinds of desire would be irrational to have for similar, distinctive reasons that having Moorean beliefs would be irrational to have. (...) Hence, I argue that such desires, a desire that ?one have a particular desire that was frustrated? or a desire that ?some state of affairs obtain about which one was indifferent?, are a parallel Moorean paradox of desire. I further argue that this analogous paradox has implications for practical reasoning, in particular by presenting a problem for instrumentalism about the objects of desire. (shrink)

The development of modern science, as everybody knows, has come largely through naturalizing domains of inquiry that were historically parts of philosophy. Theories based on mere speculation about matters empirical, such as Aristotle‟s view about teleology in nature, were replaced with law-based, predictive explanatory theories that invoked empirical data as supporting evidence. Although philosophers have, by and large, applauded such developments, inquiry into normative domains presents a different set of problems, and there is no consensus about whether such an inquiry (...) can be naturalized. Since the early twentieth century, attempts at naturalizing ethics have been at the center of heated debates, and later attempts at naturalizing epistemology triggered similarly contentious disputes. In ethics, of course, it was not only the Humean and Moorean arguments of early nonnaturalists and noncognitivists that raised doubts about naturalism, but also the arguments of nihilists, who later joined the chorus of criticism, rejecting any ontology that would countenance moral properties and facts. In epistemology, Quinean eliminativism brought reactions that questioned the consistency of naturalism and asked whether it could accommodate the normativity of fundamental epistemic notions such as belief and knowledge. There have so far been no similarly substantial reactions to attempts at naturalizing inquiry into another normative domain, that of reasoning. We hope to remedy that by offering 1 here a response to some recent efforts by experimental philosophers. Experimentalism about reasoning is a radical naturalistic program that rejects reflective-equilibrium accounts of the epistemic grounds for the rules of inference. If we ignore other attempts at justifying those rules a priori by, for instance, appeal to self-evidence, then those invoking Goodmanian reflective equilibrium can be considered the standard analytic accounts (hereafter, „SAA‟). Of concern here is an objection to SAA, the cognitive-diversity argument,1 that is part of a broader experimentalist critique of analytic epistemology.. (shrink)

“Moorean Dogmatist” responses to external world skepticism endorse courses of reasoning that many people find objectionable. This paper seeks to locate this dissatisfaction in considerations about epistemic responsibility. I sketch a theory of immediate warrant and show how it can be combined with plausible “inferential internalist” demands arising from considerations of epistemic responsibility. The resulting view endorses immediate perceptual warrant but forbids the sort of reasoning that “Moorean Dogmatism” would allow. A surprising result is that Dogmatism’s (...) commitment to immediate epistemic warrant isn’t enough to avoid certain standard arguments for skepticism about the external world. (shrink)

There is abundant evidence of contextual variation in the use of “S knows p.” Contextualist theories explain this variation in terms of semantic hypotheses that refer to standards of justification determined by “practical” features of either the subject’s context (Hawthorne & Stanley) or the ascriber’s context (Lewis, Cohen, & DeRose). There is extensive linguistic counterevidence to both forms. I maintain that the contextual variation of knowledge claims is better explained by common pragmatic factors. I show here that one is variable (...) strictness. “S knows p” is commonly used loosely to implicate “S is close enough to knowing p for contextually indicated purposes.” A pragmatic account may use a range of semantics, even contextualist. I use an invariant semantics on which knowledge requires complete justification. This combination meets the Moorean constraint as well as any linguistic theory should, and meets the intuition constraint much better than contextualism. There is no need for ad hoc error theories. The variation in conditions of assertability and practical rationality is better explained by variably strict constraints. It will follow that “S knows p” is used loosely to implicate that the condition for asserting “p” and using it in practical reasoning are satisfied. (shrink)

Knowledge and Presuppositions develops a novel account of epistemic contextualism based on the idea that pragmatic presuppositions play a central role in the semantics of knowledge attributions. According to Blome-Tillmann, knowledge attributions are sensitive to what is pragmatically presupposed at the context of ascription. The resulting theory--Presuppositional Epistemic Contextualism (PEC)--is simple and straightforward, yet powerful enough to have far-reaching and important consequences for a variety of hotly debated issues in epistemology and philosophy of language. -/- In this book, Blome-Tillmann first (...) develops Presuppositional Epistemic Contextualism and then explores its ability to resolve various sceptical paradoxes and puzzles. Blome-Tillmann also defends PEC against familiar and widely discussed philosophical and linguistic objections to contextualism. In the final chapters of the book PEC is employed to illuminate a variety of concerns central to contemporary discussions of epistemological issues, such as Gettier cases, Moorean reasoning, the nature of evidence, and other current problems and puzzles.

Most promising responses to skepticism fall into “Moorean” or “rationalist” camps. Mooreans believe that some apparently circular forms of reasoning allow us to have justification to believe that skeptical hypotheses are false. Rationalists believe that we have a priori justification to believe that skeptical hypotheses are false. It can seem that anti-skeptics are stuck choosing between fishy circular reasoning and mysterious a priori justification. I present a new difficulty for rationalism by focusing on skeptical scenarios wherein our (...) faculties of a priori reasoning are untrustworthy. In dealing with these scenarios, rationalists end up having to embrace the same sorts of circular reasoning that Mooreans use to deal with more familiar skeptical scenarios. As a result, there is no viable diagnosis of what's wrong with Moorean reasoning that does not also apply to rationalism: both anti-skeptical approaches are in the same boat when it comes to embracing circular reasoning.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, (...) subjective Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

Robert Batterman examines a form of scientific reasoning called asymptotic reasoning, arguing that it has important consequences for our understanding of the scientific process as a whole.

With clarity and rigor, he simplifies complex questions about universal behavior, demonstrating a profound understanding of the underlying structures that ground them. This book introduces a valuable new method that is certain to fill explanatory gaps across (...) disciplines. (shrink)

This book represents the first major attempt by any author to provide an integrated account of the evidence for bias in human reasoning across a wide range of disparate psychological literatures. The topics discussed involve both deductive and inductive reasoning as well as statistical judgement and inference. In addition, the author proposes a general theoretical approach to the explanations of bias and considers the practical implications for real world decision making. The theoretical stance of the book is based (...) on a distinction between preconscious heuristic processes which determine the mental representation of 'relevant' features of the problem content, and subsequent analytic reasoning processes which generate inferences and judgements. Phenomena discussed and interpreted within this framework include feature matching biases in propositional reasoning, confirmation bias, biasing and debiasing effects of knowledge on reasoning, and biases in statistical judgement normally attributed to 'availability' and 'representativeness' heuristics. In the final chapter, the practical consequences of bias for real life decision making are considered, together with various issues concerning the problem of 'debiasing'. The major approaches discussed are those involving education and training on the one hand, and the development of intelligent software and interactive decision aids on the other. (shrink)

Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

Distinctions have been proposed between systems of reasoning for centuries. This article distills properties shared by many of these distinctions and characterizes the resulting systems in light of recent findings and theoretical developments. One system is associative because its computations reflect similarity structure and relations of temporal contiguity. The other is "rule based" because it operates on symbolic structures that have logical content and variables and because its computations have the properties that are normally assigned to rules. The systems (...) serve complementary functions and can simultaneously generate different solutions to a reasoning problem. The rule-based system can suppress the associative system but not completely inhibit it. The article reviews evidence in favor of the distinction and its characterization. (shrink)

Active reasoning is the kind of reasoning that we do deliberately and consciously. In characterizing the nature of active reasoning and the norms it should obey, the question arises which attitudes we can reason with. Many authors take outright beliefs to be the attitudes we reason with. Others assume that we can reason with both outright beliefs and degrees of belief. Some think that we reason only with degrees of belief. In this paper I approach the question (...) of what kinds of beliefs can participate in reasoning by using the following method: I take the default position to be maximally permissive – that both graded and outright beliefs can participate in reasoning. I then identify some features of active reasoning that appear at first glance to favor a more restrictive position about which types of belief we can reason with. I argue that the arguments based on these features ultimately fail. (shrink)

This paper tries to do three things. First, it tries to make it plausible that correct rules of reasoning do not always preserve justification: in other words, if you begin with a justified attitude, and reason correctly from that premise, it can nevertheless happen that you’ll nevertheless arrive at an unjustified attitude. Attempts to show that such cases in fact involve following an incorrect rule of reasoning cannot be vindicated. Second, it also argues that correct rules of (...) class='Hi'>reasoning do not even correspond to permissions of “structural rationality”: it is not always structurally permissible to base an attitude on other attitudes from which it follows by correct reasoning. Third, from these observations it tries to build a somewhat positive account of the correctness of rules of reasoning as a more sui generis notion irreducible to either justification or structural rationality. This account vindicates an important unity of theoretical and practical reasoning as well as a qualified version of the thesis that deductive logic supplies correct rules of reasoning. (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)

Change, Choice and Inference develops logical theories that are necessary both for the understanding of adaptable human reasoning and for the design of intelligent systems.

The book unifies lively and significant strands of research in logic, philosophy, economics (...) and artificial intelligence. It elaborates on the relevant theories and provides a mathematically precise foundation for the thesis that large parts of theoretical reason can be subsumed under practical reason. (shrink)

An organizing theme of the dissertation is the issue of how to make philosophical theories useful for scientific purposes. An argument for the contention is presented that it doesn’t suffice merely to theoretically motivate one’s theories, and make them compatible with existing data, but that philosophers having this aim should ideally contribute to identifying unique and hard to vary predictions of their theories. This methodological recommendation is applied to the ranking-theoretic approach to conditionals, which emphasizes the epistemic relevance and the (...) expression of reason relations as part of the semantics of the natural language conditional. As a first step, this approach is theoretically motivated in a comparative discussion of other alternatives in psychology of reasoning, like the suppositional theory of conditionals, and novel approaches to the problems of compositionality and accounting for the objective purport of indicative conditionals are presented. In a second step, a formal model is formulated, which allows us to derive quantitative predictions from the ranking-theoretic approach, and it is investigated which novel avenues of empirical research that this model opens up for. Finally, a treatment is given of the problem of logical omniscience as it concerns the issue of whether ranking theory (and other similar approaches) makes too idealized assumptions about rationality to allow for interesting applications in psychology of reasoning. Building on the work of Robert Brandom, a novel solution to this problem is presented, which both opens up for new perspectives in psychology of reasoning and appears to be capable of satisfying a range of constraints on bridge principles between logic and norms of reasoning, which would otherwise stand in a tension.

According to Aristotle, humans are the rational animal. The borderline between rationality and irrationality is fundamental to many aspects of human life including the law, mental health, and language interpretation. But what is it to be rational? One answer, deeply embedded in the Western intellectual tradition since ancient Greece, is that rationality concerns reasoning according to the rules of logic – the formal theory that specifies the inferential connections that hold with certainty between propositions. Piaget viewed logical reasoning (...) as defining the end-point of cognitive development; and contemporary psychology of reasoning has focussed on comparing human reasoning against logical standards.

This book identifies 25 argumentation schemes for presumptive reasoning and matches a set of critical questions to each.

Reasoning is a certain kind of attitude-revision. What kind? The aim of this paper is to introduce and defend a new answer to this question, based on the idea that reasoning is a goodness-fixing kind. Our central claim is that reasoning is a functional kind: it has a constitutive point or aim that fixes the standards for good reasoning. We claim, further, that this aim is to get fitting attitudes. We start by considering recent accounts of (...) reasoning due to Ralph Wedgwood and John Broome, and argue that, while these accounts contain important insights, they are not satisfactory: Wedgwood’s rules out too much, and Broome’s too little. We then introduce and defend our alternative account, discuss some of its implications and attractions, and, finally, consider objections. (shrink)

According to an increasingly popular epistemological view, people need outright beliefs in addition to credences to simplify their reasoning. Outright beliefs simplify reasoning by allowing thinkers to ignore small error probabilities. What is outright believed can change between contexts. It has been claimed that thinkers manage shifts in their outright beliefs and credences across contexts by an updating procedure resembling conditionalization, which I call pseudo-conditionalization (PC). But conditionalization is notoriously complicated. The claim that thinkers manage their beliefs via (...) PC is thus in tension with the view that the function of beliefs is to simplify our reasoning. I propose to resolve this puzzle by rejecting the view that thinkers employ PC. Based on this solution, I furthermore argue for a descriptive and a normative claim. The descriptive claim is that the available strategies for managing beliefs and credences across contexts that are compatible with the simplifying function of outright beliefs can generate synchronic and diachronic incoherence in a thinker’s attitudes. Moreover, I argue that the view of outright belief as a simplifying heuristic is incompatible with the view that there are ideal norms of coherence or consistency governing outright beliefs that are too complicated for human thinkers to comply with.

This paper explores the sense in which rational requirements govern our attitudes like belief and intention. I argue that there is a tension between the idea that rational requirements govern attitudes understood as standing states and the attractive idea that we can directly satisfy the requirements by performing reasoning. I identify the tension by (a) illustrating how a dispositional conception of belief can cause trouble for the idea that we can directly revise our attitudes through reasoning by considering (...) John Broome's view, and (b) advancing a general argument that a standing state cannot be directly affected by reasoning. I then propose a solution: by recognizing the proper targets of rational requirements as occurrent, rather than dispositional attitudes, we can preserve the idea that we can directly satisfy rational requirements through reasoning.

Human agents draw a variety of inferences effortlessly, spontaneously, and with remarkable efficiency – as though these inferences were a reflexive response of their cognitive apparatus. Furthermore, these inferences are drawn with reference to a large body of background knowledge. This remarkable human ability seems paradoxical given the complexity of reasoning reported by researchers in artificial intelligence. It also poses a challenge for cognitive science and computational neuroscience: How can a system of simple and slow neuronlike elements represent a (...) large body of systemic knowledge and perform a range of inferences with such speed? We describe a computational model that takes a step toward addressing the cognitive science challenge and resolving the artificial intelligence paradox. We show how a connectionist network can encode millions of facts and rules involving n-ary predicates and variables and perform a class of inferences in a few hundred milliseconds. Efficient reasoning requires the rapid representation and propagation of dynamic bindings. Our model (which we refer to as SHRUTI) achieves this by representing (1) dynamic bindings as the synchronous firing of appropriate nodes, (2) rules as interconnection patterns that direct the propagation of rhythmic activity, and (3) long-term facts as temporal pattern-matching subnetworks. The model is consistent with recent neurophysiological evidence that synchronous activity occurs in the brain and may play a representational role in neural information processing. The model also makes specific psychologically significant predictions about the nature of reflexive reasoning. It identifies constraints on the form of rules that may participate in such reasoning and relates the capacity of the working memory underlying reflexive reasoning to biological parameters such as the lowest frequency at which nodes can sustain synchronous oscillations and the coarseness of synchronization.

While there is much evidence for the influence of automatic emotional responses on moral judgment, the roles of reflection and reasoning remain uncertain. In Experiment 1, we induced subjects to be more reflective by completing the Cognitive Reflection Test prior to responding to moral dilemmas. This manipulation increased utilitarian responding, as individuals who reflected more on the CRT made more utilitarian judgments. A follow-up study suggested that trait reflectiveness is also associated with increased utilitarian judgment. In Experiment 2, subjects (...) considered a scenario involving incest between consenting adult siblings, a scenario known for eliciting emotionally driven condemnation that resists reasoned persuasion. Here, we manipulated two factors related to moral reasoning: argument strength and deliberation time. These factors interacted in a manner consistent with moral reasoning: A strong argument defending the incestuous behavior was more persuasive than a weak argument, but only when increased deliberation time encouraged subjects to reflect.

At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such challenges, (...) and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

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.

The chapter reviews recent theoretical and empirical developments concerning the theory of team reasoning in game theoretic interactions.

What is the relationship between the epistemic norms of assertion and the epistemic norms of action/practical reasoning? Brown argues that the standards for practical reasoning and assertion are distinct (Brown 2012). In contrast, Montminy argues that practical reasoning and assertion must be governed by the same norm (Montminy 2012). Likewise, McKinnon has articulated an argument for a unified account from cases of isolated second-hand knowledge (McKinnon 2012). To clarify the issue, I articulate a distinction between Equivalence Commonality (...) and Structural Commonality. I then argue against the former by counterexamples that doubly dissociate the standards for assertion and action. Furthermore, I argue that such a double dissociation compromises knowledge accounts of both assertion and action/practical reasoning. To provide a more accurate diagnosis, I consider speech act theory and argue that principled differences between the norms of action and assertion compromise Equivalence Commonality. In contrast, a qualified version of Structural Commonality may be preserved. (shrink)

In section 1, I develop epistemic communism, my view of the function of epistemically evaluative terms such as ‘rational’. The function is to support the coordination of our belief-forming rules, which in turn supports the reliable acquisition of beliefs through testimony. This view is motivated by the existence of valid inferences that we hesitate to call rational. I defend the view against the worry that it fails to account for a function of evaluations within first-personal deliberation. In the rest of (...) the paper, I then argue, on the basis of epistemic communism, for a view about rationality itself. I set up the argument in section 2 by saying what a theory of rational deduction is supposed to do. I claim that such a theory would provide a necessary, sufficient, and explanatorily unifying condition for being a rational rule for inferring deductive consequences. I argue in section 3 that, given epistemic communism and the conventionality that it entails, there is no such theory. Nothing explains why certain rules for deductive reasoning are rational.

This book by one of the world's foremost philosophers in the fields of epistemology and logic offers an account of suppositional reasoning relevant to practical deliberation, explanation, prediction and hypothesis testing. Suppositions made 'for the sake of argument' sometimes conflict with our beliefs, and when they do, some beliefs are rejected and others retained. Thanks to such belief contravention, adding content to a supposition can undermine conclusions reached without it. Subversion can also arise because suppositional reasoning is ampliative. (...) These two types of nonmonotonic logic are the focus of this book. A detailed comparison of nonmonotonicity appropriate to both belief contravening and ampliative suppositional reasoning reveals important differences that have been overlooked. (shrink)

The growing trend of required ethics instruction in the business school curriculum has created a need for relevant teaching materials. In response to this need the Journal of Business Ethics is introducing a new case section.

This article discusses how business ethics cases can facilitate the development of deductive, inductive and critical reasoning skills.

This article outlines a theory of naive probability. According to the theory, individuals who are unfamiliar with the probability calculus can infer the probabilities of events in an extensional way: They construct mental models of what is true in the various possibilities. Each model represents an equiprobable alternative unless individuals have beliefs to the contrary, in which case some models will have higher probabilities than others. The probability of an event depends on the proportion of models in which it occurs. (...) The theory predicts several phenomena of reasoning about absolute probabilities, including typical biases. It correctly predicts certain cognitive illusions in inferences about relative probabilities. It accommodates reasoning based on numerical premises, and it explains how naive reasoners can infer posterior probabilities without relying on Bayes's theorem. Finally, it dispels some common misconceptions of probabilistic reasoning. (shrink)

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)

Previous research indicates that ethical ideologies, issue-contingencies, and social context can impact ethical reasoning in different business situations. However, the manner in which these constructs work together to shape different steps of the ethical decision-making process is not always clear. The purpose of this study was to address these issues by exploring the influence of idealism and relativism, perceived moral intensity in a decision-making situation, and social context on the recognition of an ethical issue and ethical intention. Utilizing a (...) sales-based scenario and multiple ethics measures included on a self-report questionnaire, data were collected from a regional sample of business students, most of whom had modest work experience. The results indicated that perceived moral intensity was associated with increased ethical issue recognition and ethical intention. Idealism was also associated with increased ethical issue recognition, and relativism was associated with decreased ethical intention. Social consensus was positively related to ethical issue recognition and intention, while competitive context was inversely related to ethical intention. Finally, ethical issue recognition was associated with increased ethical intention. Idealism, moral intensity, social consensus, and work experience worked together as predictors of ethical issue recognition, whereas recognition of an ethical issue, relativism, moral intensity, social consensus, and competitive context worked together to predict ethical intention.

While models of business ethics increasingly recognize that ethical behavior varies cross-culturally, scant attention has been given to understanding how culture affects the ethical reasoning process that predicates individuals' ethical actions. To address this gap, this paper illustrates how culture may affect the various components of individuals' ethical reasoning by integrating findings from the cross-cultural management literature with cognitive-developmental perspective. Implications for future research and transnational organizations are discussed.

Elaborating on the notions that humans possess different modalities of decision-making and that these are often influenced by moral considerations, we conducted an experimental investigation of the Trolley Problem. We presented the participants with two standard scenarios (‹lever’ and ‹stranger’) either in the usual or in reversed order. We observe that responses to the lever scenario, which result from (moral) reasoning, are affected by our manipulation; whereas responses to the stranger scenario, triggered by moral emotions, are unaffected. Furthermore, when (...) asked to express general moral opinions on the themes of the Trolley Problem, about half of the participants reveal some inconsistency with the responses they had previously given.

Although deductive reasoning is a closed system, one's beliefs about the world can influence validity judgements. To understand the associated functional neuroanatomy of this belief-bias we studied 14 volunteers using event-related fMRI, as they performed reasoning tasks under neutral, facilitatory and inhibitory belief conditions. We found evidence for the engagement of a left temporal lobe system during belief-based reasoning and a bilateral parietal lobe system during belief-neutral reasoning. Activation of right lateral prefrontal cortex was evident when (...) subjects inhibited a prepotent response associated with belief-bias and correctly completed a logical task, a finding consistent with its putative role in cognitive monitoring. By contrast, when logical reasoning was overcome by belief-bias, there was engagement of ventral medial prefrontal cortex, a region implicated in affective processing. This latter involvement suggests that belief-bias effects in reasoning may be mediated through an influence of emotional processes on reasoning. (shrink)

An important objection to political liberalism is that it provides no means by which to decide conflicts between public and non-public reasons. This article develops John Rawls' idea of `reasoning from conjecture' as one way to argue for a commitment to public reason. Reasoning from conjecture is a form of non-public justification that allows political liberals to reason from within the comprehensive views of at least some unreasonable citizens. After laying out the basic features of this form of (...) non-public justification, this article responds to three objections based on concerns about insincerity, cultural imperialism, and the epistemic authority of those who reason from conjecture.

When and why does it matter whether we can give an explicit justification for what we believe? This paper examines these questions in the light of recent empirical work on the social functions served by our capacity to reason, in particular, Mercier and Sperber’s argumentative theory of reasoning.

In this paper I am concerned with the question of whether degrees of belief can figure in reasoning processes that are executed by humans. It is generally accepted that outright beliefs and intentions can be part of reasoning processes, but the role of degrees of belief remains unclear. The literature on subjective Bayesianism, which seems to be the natural place to look for discussions of the role of degrees of belief in reasoning, does not address the question (...) of whether degrees of belief play a role in real agents’ reasoning processes. On the other hand, the philosophical literature on reasoning, which relies much less heavily on idealizing assumptions about reasoners than Bayesianism, is almost exclusively concerned with outright belief. One possible explanation for why no philosopher has yet developed an account of reasoning with degrees of belief is that reasoning with degrees of belief is not possible for humans. In this paper, I will consider three arguments for this claim. I will show why these arguments are flawed, and conclude that, at least as far as these arguments are concerned, it seems like there is no good reason why the topic of reasoning with degrees of belief has received so little attention.

Recent research in moral psychology highlights the role of emotion and intuition in moral judgment. In the wake of these findings, the role and significance of moral reasoning remain uncertain. In this article, we distinguish among different kinds of moral reasoning and review evidence suggesting that at least some kinds of moral reasoning play significant roles in moral judgment, including roles in abandoning moral intuitions in the absence of justifying reasons, applying both deontological and utilitarian moral principles, (...) and counteracting automatic tendencies toward bias that would otherwise dominate behavior. We argue that little is known about the psychology of moral reasoning and that it may yet prove to be a potent social force. (shrink)

Since at least the 1960s, deontic logicians and ethicists have worried about whether there can be normative systems that allow conflicting obligations. Surprisingly, however, little direct attention has been paid to questions about how we may reason with conflicting obligations. In this paper, I present a problem for making sense of reasoning with conflicting obligations and argue that no deontic logic can solve this problem. I then develop an account of reasoning based on the popular idea in ethics (...) that reasons explain obligations and show that it solves this problem. (shrink)
