It would surely have been better to entitle this work ‘Reflexions on ethical theories’, for it cannot in any true sense of the word be called a study, a scientific study which entails detailed analysis and positive criticism. In fact Professor Mackinnon presents us with a series of considerations, highly personal and at times indeed penetrating and instructive, on the moral theories of certain British and continental philosophers—of the 19th century utilitarians ; of Kant, Hegel and their followers; of (...) the theologianphilosopher bishop of Durham, Joseph Butler; of Russell, Moore and others. The impression left on one after a careful perusal of the work is that it is no more than an agglomeration of ‘mights’ and ‘perhaps’, never a clear–cut judgment. The chief general defect of the book and the cause of much obscurity is certainly this: the absence of any welldefined distinction between exposé and critique. As often as not one does not know what the opinion of the author is as distinct from his interpretation of the authors he is studying. This defect would seem to be characteristic of a great part of the ethical writing produced by the Scottish and British schools, when they do not reduce ethical theory to anything better than semasiology, to a study of ethical language or linguistic usage. Prof. Mackinnon has certainly not freed himself from the ‘present confused state of moral philosophy in this country’, which he so rightly condemns. I had thought that all philosophers, of whatever ilk, were agreed that ethical science or moral philosophy was nothing more than the study of the human being on its way towards completeness in human being, from an initial embryonic stage, as it were, to the full flowering of human perfection, manifested in perfect human being and perfect human life—a journey or precess directed and controlled by the human subject itself, fully conscious of the end to be achieved and conscious too of the steps or means towards it. I would have thought too that if we are to set up moral science as distinct from mere semasiology, or from psychology, biology, zoology or botany, then all were agreed that we have to do with the domain of free activity, of voluntary conscious activity, which obviously brings with it the order of responsibility and willed subjection to a given objective order of things, that is, of human nature itself and human perfection. I would have taken for granted too that one could study all this field of the free development of the human being towards its ultimate perfection either with a view to the acquisition of knowledge and nothing more, or precisely with a view to being in a position to direct oneself and others towards that fullness of being. That would give us two distinct modes of moral or ethical theory, the speculative or theoretical and the practical and normative, the resolutive and the compositive. I am not so sure that Professor Mackinnon is ready to admit these presupposita. He speaks of the ‘curious and almost silly claim that we are free’, and at the same time he can write about the ‘frankly metaphysical reality of freedom’, or its ‘near–metaphysical reality’. This, in the language of the author, is just another way of proclaiming that human freedom is no more than a myth, lacking all substance and reality. Moral science as distinct from all other sciences, one would think, presupposes that the moral subject be conscious of itself and its activity, that is, that it fully and clearly know that its life and its activity is its own. It must be master of its own actions, and in that sense truly master of its own destiny. Then and only then are we in the order of moral activity. However, we are warned by Professor Mackinnon that “to know that an action is mine is a very strange sort of knowledge, quite different from knowing that an apple or a book is mine: to use the word ‘know’ in such a context is a venture fraught with intellectual peril”. I sincerely think it would have been better had the author denied straight out the possibility, not just of metaphysics, but of ethical theory tout court; for he denies often enough the existence of the moral subject, namely, man freely and deliberately ordaining himself towards human consummation. Had he done that at the outset he would have been spared the trouble of writing his book. All in all, one gets the distinct impression that the author is just not sure of his ground and has no really sound criterion whereby to judge of various ethical theories. In fact the book ends with a big question–mark: ‘If we speak and write thus, do we speak and write sound and fury signifying nothing?’. Reluctantly I am constrained to answer in the affirmative. And I should like to add, so as not to appear completely destructive, but in some way constructive: if, instead of dismissing Aristotle and his followers, ancient and modern, as mere ‘intuitionists’, Professor Mackinnon would only study them seriously he would first of all find out how unjustified is his condemnation of them and then, I venture to suggest, he would acquire a light to guide him surely through the maze of ethical theory with which he grapples aimlessly and would thus be enabled to extricate himself from ‘the present confused state of moral philosophy’ in Britain.

In this paper, I consider the relationship between Inference to the Best Explanation and Bayesianism, both of which are well-known accounts of the nature of scientific inference. In Sect. 2, I give a brief overview of Bayesianism and IBE. In Sect. 3, I argue that IBE in its most prominently defended forms is difficult to reconcile with Bayesianism because not all of the items that feature on popular lists of “explanatory virtues”—by means of which IBE ranks competing explanations—have confirmational import. (...) Rather, some of the items that feature on these lists are “informational virtues”—properties that do not make a hypothesis \ more probable than some competitor \ given evidence E, but that, roughly-speaking, give that hypothesis greater informative content. In Sect. 4, I consider as a response to my argument a recent version of compatibilism which argues that IBE can provide further normative constraints on the objectively correct probability function. I argue that this response does not succeed, owing to the difficulty of defending with any generality such further normative constraints. Lastly, in Sect. 5, I propose that IBE should be regarded, not as a theory of scientific inference, but rather as a theory of when we ought to “accept” H, where the acceptability of H is fixed by the goals of science and concerns whether H is worthy of commitment as research program. In this way, IBE and Bayesianism, as I will show, can be made compatible, and thus the Bayesian and the proponent of IBE can be friends. (shrink)

This book takes up the central themes of Aristotle's metaphysical theory and the various transformations they undergo prior to their full expression in the Metaphysics. Aristotle's metaphysics is bedevilled by classic puzzles involving such notions as form, predication, universal, and substance, which result from his attempt to adapt the various requirements on primary substance developed in his earlier works so that they fit the very different metaphysical picture in his later work. Professor Lewis argues that Aristotle is himself aware of (...) most if not all of these difficulties and in the Metaphysics works hard to ensure the coherence of his theory. He presents Aristotle's views as a formal theory complete with axioms, definitions, and theorems. (shrink)

We pose and resolve several vexing decision theoretic puzzles. Some are variants of existing puzzles, such as 'Trumped' (Arntzenius and McCarthy 1997), 'Rouble trouble' (Arntzenius and Barrett 1999), 'The airtight Dutch book' (McGee 1999), and 'The two envelopes puzzle' (Broome 1995). Others are new. A unified resolution of the puzzles shows that Dutch book arguments have no force in infinite cases. It thereby provides evidence that reasonable utility functions may be unbounded and that reasonable credence functions need not be countably (...) additive. The resolution also shows that when infinitely many decisions are involved, the difference between making the decisions simultaneously and making them sequentially can be the difference between riches and ruin. Finally, the resolution reveals a new way in which the ability to make binding commitments can save perfectly rational agents from sure losses. (shrink)

In this article, I will provide a critical overview of the form of non-deductive reasoning commonly known as “Inference to the Best Explanation” (IBE). Roughly speaking, according to IBE, we ought to infer the hypothesis that provides the best explanation of our evidence. In section 2, I survey some contemporary formulations of IBE and highlight some of its putative applications. In section 3, I distinguish IBE from C.S. Peirce’s notion of abduction. After underlining some of the essential elements of IBE, (...) the rest of the entry is organized around an examination of various problems that IBE confronts, along with some extant attempts to address these problems. In section 4, I consider the question of when a fact requires an explanation, since presumably IBE applies only in cases where some explanation is called for. In section 5, I consider the difficult question of how we ought to understand IBE in light of the fact that among philosophers, there is significant disagreement about what constitutes an explanation. In section 6, I consider different strategies for justifying the truth-conduciveness of the explanatory virtues, e.g., simplicity, unification, scope, etc., criteria which play an indispensable role in any given application of IBE. In section 7, I survey some of the most recent literature on IBE, much of which consists of investigations of the status of IBE from the standpoint of the Bayesian philosophy of science. (shrink)

Argumentation as the public exchange of reasons is widely thought to enhance deliberative interactions that generate and justify reasonable public policies. Adopting an argumentation-theoretic perspective, we survey the norms that should govern public argumentation and address some of the complexities that scholarly treatments have identified. Our focus is on norms associated with the ideals of correctness and participation as sources of a politically legitimate deliberative outcome. In principle, both ideals are mutually coherent. If the information needed for a correct deliberative (...) outcome is distributed among agents, then maximising participation increases information diversity. But both ideals can also be in tension. If participants lack competence or are prone to biases, a correct deliberative outcome requires limiting participation. The central question for public argumentation, therefore, is how to strike a balance between both ideals. Rather than advocating a preferred normative framework, our main purpose is to illustrate the complexity of this theme. (shrink)

This article aims to offer a refined way of understanding what we mean by the concepts of meaningfulness and meaning in life. The first step is to separate worthwhileness, as the broadest evaluation of life taking all types of values into account, from meaningfulness, which is seen as one type of intrinsic value along with, for example, well-being, moral praiseworthiness, and authenticity, which I argue are also separate types of intrinsic value. After discussing why we should not settle with the (...) currently popular fitting attitudes analysis of meaningfulness, I argue that the meaningfulness of a life should be seen to be about the positive contribution beyond itself that this particular life is able to make. I show how this analysis is different from previous similar accounts and how it is able to avoid a number of challenges that have troubled these previous accounts, such as the pleasure machine challenge, the results machine challenge, and the doing good unintentionally challenge. I also demonstrate how it is able to account for prototypical examples of meaningful and meaningless lives and how it is compatible with subjectivism, supernaturalism, and objective naturalism, which is seen as a merit. Finally, I conclude with some notes about what could make life meaningful, given the current analysis of meaningfulness itself. (shrink)

Authority arguments generate support for claims by appealing to an agent’s authority status, rather than to reasons independent of it. With few exceptions, the current literature on argument schemes acknowledges two basic authority types. The _epistemic_ type grounds in knowledge, the_ deontic_ type grounds in power. We review how historically earlier scholarship acknowledged an_ attractiveness-based_ and a _majority-based_ authority type as equally basic type. Crossing these with basic speech act types thus yields authority argument sub-schemes. Focusing on the_ epistemic-assertive_ sub-scheme (...) (‘an epistemic authority _A_ _E_ asserts a proposition _P_’), we apply a meta-level approach to specifying critical questions. Results improve the evaluation of this sub-scheme and show how similar improvements are obtainable for other schemes. (shrink)

In the last two decades, a robust consensus has emerged among philosophers of science, whereby political, ethical, or social values must play some role in scientific inquiry, and that the ‘value-free ideal’ is thus a misguided conception of science. However, the question of how to distinguish, in a principled way, which values may legitimately influence science remains. This question, which has been dubbed the ‘new demarcation problem,’ has until recently received comparatively less attention from philosophers of science. In this paper, (...) I appeal to Rawls’s theory of justice (1971) on the basis of which I defend a Rawlsian solution to the new demarcation problem. As I argue, the Rawlsian solution places plausible constraints on which values ought to influence scientific inquiry, and, moreover, can be fruitfully applied to concrete cases to determine how the conflicting interests of stakeholders should be balanced. After considering and responding to the objection that Rawls’s theory of justice applies only to the “basic structure” of society, I compare the Rawlsian solution to some other approaches to the new demarcation problem, especially those that emphasize democratic criteria.

This paper discusses ethical issues surrounding Integrated Assessment Models (IAMs) of the economic effects of climate change, and how climate economists acting as policy advisors ought to represent the uncertain possibility of catastrophe. Some climate economists, especially Martin Weitzman, have argued for a precautionary approach where avoiding catastrophe should structure climate economists’ welfare analysis. This paper details ethical arguments that justify this approach, showing how Weitzman’s “fat tail” probabilities of climate catastrophe pose ethical problems for widely used IAMs. The main (...) claim is that economists who ignore or downplay catastrophic risks in their representations of uncertainty likely fall afoul of ethical constraints on scientists acting as policy advisors. Such scientists have duties to honestly articulate uncertainties and manage (some) inductive risks, or the risks of being wrong in different ways. (shrink)

Relevant to, and drawing from, a range of disciplines, the chapters in this collection show the diversity, and applicability, of research in Bayesian argumentation.

Fifty years ago, Dieter Henrich wrote an influential little text on ‘Fichte’s Origi­nal Insight’. Seldom so much food for thought has been put in a nutshell. The essay, bearing such an unremarkable title, delivers a diagnosis of why two hundred years of penetrating thought about the internal structure of subjectivity have ended up so fruitless. Henrich’s point was: Self-consciousness cannot be explained as the result of a higher-order act, bending back upon a first-order one, given that “what reflection finds, must (...) already have been there before” (Novalis). Whereas Henrich’s discovery had some influence in German speaking countries (and was dubbed the ‘Heidelberg School’), it remained nearly unnoticed in the anglophone (and now dominant) philosophical world. This is starting to change, now that a recent view on (self-) consciousness, called ‘self-representationalism’, is beginning to develop and to discover its Heidelbergian roots. (shrink)

This paper defends the view that in a certain sense evidence is normative. Neither a bit of evidence nor the fact that it is evidence for a certain proposition is a normative fact, but it is still the case that evidence provides normative reason for belief. An argument for the main thesis will be presented. It will rely on evidentialist norms of belief and a Broomean conception of normative reasons. Two important objections will be discussed, one from A. Steglich-Petersen on (...) whether having evidence is sufficient for having a normative reason for belief and another one from S. Street.

In this article, I consider an important challenge to the popular theory of scientific inference commonly known as ‘inference to the best explanation’, one that has received scant attention.1 1 The problem is that there exists a wide array of rival models of explanation, thus leaving IBE objectionably indeterminate. First, I briefly introduce IBE. Then, I motivate the problem and offer three potential solutions, the most plausible of which is to adopt a kind of pluralism about the rival models of (...) explanation. However, I argue that how ranking explanations on this pluralistic account of IBE remains obscure and pluralism leads to contradictory results. In light of these objections, I attempt to dissolve the problem by showing why IBE does not require a ‘model’ of explanation and by giving an account of what explanation consists in within the context of IBE.

In this paper, I examine Cicero’s oft-neglected De Divinatione, a dialogue investigating the legitimacy of the practice of divination. First, I offer a novel analysis of the main arguments for divination given by Quintus, highlighting the fact that he employs two logically distinct argument forms. Next, I turn to the first of the main arguments against divination given by Marcus. Here I show, with the help of modern probabilistic tools, that Marcus’ skeptical response is far from the decisive, proto-naturalistic assault (...) on superstition that it is sometimes portrayed to be. Then, I offer an extended analysis of the second of the main arguments against divination given by Marcus. Inspired by Marcus’ second main argument, I formulate, explicate, and defend a substantive principle of scientific methodology that I call the “Ciceronian Causal-Nomological Requirement” (CCR). Roughly, this principle states that causal knowledge is essential for relying on correlations in predictive inference. Although I go on to argue that Marcus’ application of the CCR in his debate with Quintus is dialectically inadequate, I conclude that De Divinatione deserves its place in Cicero’s philosophical corpus, and that ultimately, its significance for the history and philosophy of science ought to be recognized.

If folk science means individuals having well worked out mechanistic theories of the workings of the world, then it is not feasible. Laypeople’s explanatory understandings are remarkably coarse, full of gaps, and often full of inconsistencies. Even worse, most people overestimate their own understandings. Yet recent views suggest that formal scientists may not be so different. In spite of these limitations, science somehow works and its success offers hope for the feasibility of folk science as well. The success of science (...) arises from the ways in which scientists learn to leverage understandings in other minds and to outsource explanatory work through sophisticated methods of deference and simplification of complex systems. Three studies ask whether analogous processes might be present not only in laypeople but also in young children and thereby form a foundation for supplementing explanatory understandings almost from the start of our first attempts to make sense of the world.

This paper will critically engage with Daniel Buckley's argument against “evidential minimalism” (EM), i.e., the claim that necessarily, bits of evidence (are or) provide epistemic reasons for belief. Buckley argues that in some cases, a subject has strong evidence that p (and fulfills further minimal conditions), does not believe p, but nevertheless is not epistemically criticizable and has no epistemic reason to believe p. I will defend EM by pointing out that Buckley's argument trades on an ambiguity between a strong (...) and a weak notion of criticizability. (shrink)

In the 1960s, a school formed in Heidelberg around Dieter Henrich that criticized—with reference to J. G. Fichte—the ‘reflection model’ of self-consciousness according to which self-consciousness consists in a representational relation between two mental states or the self-representation of a mental state. I present a new “Heidelberg perspective” of pre-reflective self-consciousness. According to this new approach, self-consciousness occurs in two varieties which regularly are not sufficiently distinguished: The first variety is egological self-consciousness that exists in connection with the use of (...) concepts. It consists in the consciousness of having an awareness of oneself as the Ego of a conscious state. The second variety is anonymous pre-reflective self-consciousness, which is awareness of consciousness but does not contain egological information. The pre-reflective self-consciousness does not exhibit a subject-object structure and thus cannot be appropriately determined as a representation, self-representation, or even acquaintance relation. Rather, anonymous self-consciousness is characterized by an indistinction of subject and object. However, pre-reflective self-consciousness is the basis of egological self-consciousness. (shrink)

Human cognition is unique in the way in which it relies on combinatorial (or compositional) structures. Language provides ample evidence for the existence of combinatorial structures, but they can also be found in visual cognition. To understand the neural basis of human cognition, it is therefore essential to understand how combinatorial structures can be instantiated in neural terms. In his recent book on the foundations of language, Jackendoff described four fundamental problems for a neural instantiation of combinatorial structures: the massiveness (...) of the binding problem, the problem of 2, the problem of variables, and the transformation of combinatorial structures from working memory to long-term memory. This paper aims to show that these problems can be solved by means of neural “blackboard” architectures. For this purpose, a neural blackboard architecture for sentence structure is presented. In this architecture, neural structures that encode for words are temporarily bound in a manner that preserves the structure of the sentence. It is shown that the architecture solves the four problems presented by Jackendoff. The ability of the architecture to instantiate sentence structures is illustrated with examples of sentence complexity observed in human language performance. Similarities exist between the architecture for sentence structure and blackboard architectures for combinatorial structures in visual cognition, derived from the structure of the visual cortex. These architectures are briefly discussed, together with an example of a combinatorial structure in which the blackboard architectures for language and vision are combined. In this way, the architecture for language is grounded in perception. Perspectives and potential developments of the architectures are discussed. Key Words: binding; blackboard architectures; combinatorial structure; compositionality; language; dynamic system; neurocognition; sentence complexity; sentence structure; working memory; variables; vision.

The entropy-reduction hypothesis claims that the cognitive processing difficulty on a word in sentence context is determined by the word's effect on the uncertainty about the sentence. Here, this hypothesis is tested more thoroughly than has been done before, using a recurrent neural network for estimating entropy and self-paced reading for obtaining measures of cognitive processing load. Results show a positive relation between reading time on a word and the reduction in entropy due to processing that word, supporting the entropy-reduction (...) hypothesis. Although this effect is independent from the effect of word surprisal, we find no evidence that these two measures correspond to cognitively distinct processes. (shrink)

The literature on human mate preferences is vast but most data come from studies on college students in complex societies, who represent a thin slice of cultural variation in an evolutionarily novel environment. Here, I present data on the mate preferences of men and women in a society of hunter-gatherers, the Hadza of Tanzania. Hadza men value fertility in a mate more than women do, and women value intelligence more than men do. Women place great importance on men’s foraging, and (...) both sexes rate character as important. Unlike college students, Hadza men place considerable importance on women being hard-working, and Hadza women cite looks about as often as men do. (shrink)

Ever since Kant, moral philosophers have been more or less animated by the mission of discovering inescapable law-like rules that would provide a binding justification for morality. Recently, however, many have started to question whether this is possible and what, after all, this project could achieve. An alternative vision of the task of moral philosophy starts from the pragmatist idea that philosophizing begins and ends in human experiencing. It leads to a view where morality is seen as a “social technology” (...) that aims to make living together possible, and strengthens people's capability to live a good life within a society. The role of moral philosophy is, accordingly, to develop our moral tools further. Moral philosophers become ethical engineers who use their expertise in ethical topics to criticize existing “moral technology” and construct new concepts, tools, and theories that better answer the current challenges for living a good life.

Research on corporate social responsibility has traditionally focused on managerial discretion and stakeholders’ influence. This study extends current research by addressing the effect of family firms and institutional owners on CSR performance, namely, CSR strengths and concerns. Based on stewardship theory and the socioemotional wealth perspective, we propose that family firms are more likely to value CSR performance. Next, drawing from multiple agency theory, we predict that institutional owners, unlike family owners, will influence a firm’s CSR performance differently. We tested (...) our hypotheses using a sample of 153 firms from 1994 to 2006 and found general support for our hypotheses. A higher percentage of family owned equity and the presence of a family CEO are found to increase CSR strengths, whereas transient institutional owners have an opposite effect. The presence of a family CEO and founding family are found to reduce CSR concerns. Contrary to our predictions, dedicated institutional owners are positively associated with CSR concerns. (shrink)

The paper is an investigation into the prospects of an epistemology of non-conceptual knowledge. According to the orthodox view, knowledge requires concepts and belief. I present several arguments to the effect that there is non-conceptual, non-doxastic knowledge, the obvious candidate for such knowledge being non-conceptual perception. Non-conceptual perception seems to be allowed for by cognitive scientists and it exhibits the central role features of knowledge—it plays the knowledge role: it respects an anti-luck condition, it is an achievement, it enables one (...) to act for a reason, and it provides justification. Furthermore, it makes a straightforward and elegant explanation of perceptual knowledge possible: doxastic perceptual knowledge builds on non-conceptual perception as non-conceptual knowledge. Three objections that might naturally arise will be discussed and answered. Thus, the prospects of an epistemology without belief seem to be much better than the orthodoxy wants to have it. We can extend knowledge into the non-conceptual realm. (shrink)

While the rule of law is surely a very important good, the familiar discussions found in the literature lead many to conclude that it is either a relatively trivial political ideal, or else a redundant one. What is needed is a new and persuasive defense of the rule of law that properly reflects its great significance for human well being. An important step towards building such an argument is to question a widely-shared but often unnoticed assumption that the rule of (...) law should be understood as a virtue of legal systems. The path is then cleared for a republican argument built on two theses: first, the thought that an ideal society would be one in which no one is the master of anyone else, and second, the thought that our freedom from domination is not natural or pre-institutional.

The frame model, originating in artificial intelligence and cognitive psychology, has recently been applied to change-phenomena traditionally studied within history and philosophy of science. Its application purpose is to account for episodes of conceptual dynamics in the empirical sciences suggestive of incommensurability as evidenced by “ruptures” in the symbolic forms of historically successive empirical theories with similar classes of applications. This article reviews the frame model and traces its development from the feature list model. Drawing on extant literature, examples of (...) frame-reconstructed taxonomic change are presented. This occurs for purposes of comparison with an alternative tool, conceptual spaces. The main claim is that conceptual spaces save the merits of the frame model and provide a powerful model for conceptual change in scientific knowledge, since distinctions arising in measurement theory are native to the model. It is suggested how incommensurability as incomparability of theoretical frameworks might be avoided. Moreover, as nontranslatability of worldviews, it need not to be treated as a genuine problem of conceptual representation. The status of laws vis à vis their dimensional bases as well as diachronic similarity measures are discussed. (shrink)

This critical note responds to Guiaşu and Tindale’s “Logical fallacies and invasion biology,” from our perspective as ecologists and philosophers of science engaged in debates about invasion biology and invasive species. We agree that “the level of charges and dismissals” surrounding these debates might be “unhealthy” and that “it will be very difficult for dialogues to move forward unless genuine attempts are made to understand the positions being held and to clarify the terms involved.” Although they raise several important scientific, (...) conceptual, and ethical issues at the foundations of invasion biology, we believe Guiaşu and Tindale’s attempts to clarify the debate were unsuccessful. Like some other critics of the field, they tend to misrepresent invasion biology by cherry-picking and constructing “straw people,” inaccurately portraying invasion biology, and thus failing to elevate the dialogue. In this critique, we clarify areas in the invasion biology literature misrepresented by Guiaşu and Tindale. We attempt to provide a more balanced view of areas of reasonable debate within invasion biology, including disputes about empirical evidence, diverse risk attitudes, and other diverse ethical commitments.

Contemporary liberalism and republicanism present clearly distinct programs for domestic politics, but the same cannot be said when it comes to global politics: the burgeoning literature on global republicanism has reproduced the divide between cosmopolitan and associational views familiar from long-standing debates among liberal egalitarians. Should republicans be cosmopolitans? Despite presence of a range of views in the literature, there is an emerging consensus that the best answer is no. This paper aims to resist the emerging consensus, arguing that republicans (...) should be cosmopolitans. The considerations offered against cosmopolitanism generally rest on an incomplete understanding of the relationship between economic inequality or poverty on the one hand, and domination on the other. Insofar as republicans agree that promoting freedom from domination should be our central political aim, they should regard the reduction of economic inequality and poverty at home and abroad as equally pressing.

This note argues that a belief is knowledge if it's true, certain (i.e. a full belief) and obtained by a reliable process.

This article provides a brief selective overview and discussion of recent research into natural language argumentation that may inform the study of human reasoning on the assumption that an episode of argumentation issues an invitation to accept a corresponding inference. As this research shows, arguers typically seek to establish new consequences based on prior information. And they typically do so vis-à-vis a real or an imagined opponent, or an opponent-position, in ways that remain sensitive to considerations of context, audiences, and (...) goals. Deductively valid inferences remain a limiting case of such reasoning. In view of these insights, it may appear less surprising that allegedly “irrational” behavior can regularly be produced in experimental settings that expose subjects to standardized reasoning tasks.

In this paper, I discuss the ways in which epistemic anxiety promotes well-being, specifically by examining the positive contributions that feelings of epistemic anxiety make toward intellectually virtuous inquiry. While the prospects for connecting the concept of epistemic anxiety to the two most prominent accounts of intellectual virtue, i.e., “virtue-reliabilism” and “virtue-responsibilism”, are promising, I primarily focus on whether the capacity for epistemic anxiety counts as an intellectual virtue in the reliabilist sense. As I argue, there is a close yet (...) unexplored connection between feelings of epistemic anxiety and the form of inference commonly known as “Inference to the Best Explanation” (IBE). Specifically, I argue that both the recognition that some fact requires an explanation—a necessary first step in applying IBE—and the subsequent motivation to employ IBE are typically facilitated by feelings of epistemic anxiety. So, provided IBE is truth-conducive the capacity for epistemic anxiety should count as an intellectual virtue in the reliabilist sense. After outlining my main argument, I address the challenge that the capacity for epistemic anxiety has the potential to be misleading. To respond to this challenge, I discuss how our recognition that a fact requires an explanation must in part be a species of practical knowledge, rather than theoretical knowledge. For the agent to skillfully distinguish between facts that require an explanation and facts that do not, she must develop the virtuous disposition to feel the appropriate amount of epistemic anxiety. Despite the many negative aspects associated with anxiety, as I conclude, being disposed to feel the appropriate amount of epistemic anxiety is ultimately good for us. (shrink)
