Virtues are acquirable, so if intellectual humility is a virtue, it’s acquirable. But there is something deeply problematic—perhaps even paradoxical—about aiming to be intellectually humble. Drawing on Edward Slingerland’s analysis of the paradoxical virtue of wu-wei in Trying Not To Try (New York: Crown, 2014), we argue for an anti-individualistic conception of the trait, concluding that one’s intellectual humility depends upon the intellectual humility of others. Slingerland defines wu-wei as the “dynamic, effortless, and unselfconscious state of mind of a person (...) who is optimally active and effective” (Trying Not to Try, 7). Someone who embodies wu-wei inspires implicit trust, so it is beneficial to appear wu-wei. This has led to an arms race between faking wu-wei on the one hand and detecting fakery on the other. Likewise, there are many benefits to being (or seeming to be) intellectually humble. But someone who makes conscious, strategic efforts to appear intellectually humble is ipso facto not intellectually humble. Following Slingerland’s lead, we argue that there are several strategies one might pursue to acquire genuine intellectual humility, and all of these involve commitment to shared social or epistemic values, combined with receptivity to feedback from others, who must in turn have and manifest relevant intellectual virtues. In other words, other people and shared values are partial bearers of a given individual’s intellectual humility. If this is on the right track, then acquiring intellectual humility demands epistemic anti-individualism. (shrink)

Gossip is often serious business, not idle chitchat. Gossip allows those oppressed to privately name their oppressors as a warning to others. Of course, gossip can be in error. The speaker may be lying or merely have lacked sufficient evidence. Bias can also make those who hear the gossip more or less likely to believe the gossip. By examining the social functions of gossip and considering the differences in power dynamics in which gossip can occur, we contend that gossip may (...) be not only permissible but virtuous, both as the only reasonable recourse available and as a means of resistance against oppression.

The speech act of bragging has never been subjected to conceptual analysis until now. We argue that a speaker brags just in case she makes an utterance that is an assertion and is intended to impress the addressee with something about the speaker via the belief produced by the speaker's assertion. We conclude by discussing why it is especially difficult to cancel a brag by prefacing it with, ‘I'm not trying to impress you, but…’ and connect this discussion with Moore's (...) paradox and the recent neologism ‘humblebrag’.

In the last decade, experimental philosophers have documented systematic asymmetries in the attributions of mental attitudes to agents who produce different types of side effects. We argue that this effect is driven not simply by the violation of a norm, but by salient-norm violation. As evidence for this hypothesis, we present two new studies in which two conflicting norms are present, and one or both of them is raised to salience. Expanding one’s view to these additional cases presents, we argue, (...) a fuller conception of the side-effect effect, which can be reversed by reversing which norm is salient. (shrink)

Recent findings in experimental philosophy have revealed that people attribute intentionality, belief, desire, knowledge, and blame asymmetrically to side- effects depending on whether the agent who produces the side-effect violates or adheres to a norm. Although the original (and still common) test for this effect involved a chairman helping or harming the environment, hardly any of these findings have been applied to business ethics. We review what little exploration of the implications for business ethics has been done. Then, we present (...) new experimental results that expand the attribution asymmetry to virtue and vice. We also examine whether it matters to people that an effect was produced as a primary or side- effect, as well as how consumer habits might be affected by this phenomenon. These results lead to the conclusion that it appears to be in a businessperson’s self-interest to be virtuous. (shrink)

Gossip is rarely praised. There seems little virtuous that is about talking behind someone’s back. Whether there is anything virtuous about gossip, however, depends on the kind of gossip. Some gossip is idle, but some evaluative gossip promulgates and enforces norms. When properly motivated, such gossip effects positive change in society and counts as gossiping well. The virtue of gossiping well even includes some kinds of false gossip, namely the sort that exaggerates a pre-existing trait, thereby creating a caricature of (...) a person’s character in order to establish a moral exemplar (or anti-exemplar).

This paper contributes to the underdeveloped field of experimental philosophy of science. We examine variability in the philosophical views of scientists. Using data from Toolbox Dialogue Initiative, we analyze scientists’ responses to prompts on philosophical issues (methodology, confirmation, values, reality, reductionism, and motivation for scientific research) to assess variance in the philosophical views of physical scientists, life scientists, and social and behavioral scientists. We find six prompts about which differences arose, with several more that look promising for future research. We (...) then evaluate the difference between the natural and social sciences and the challenge of interdisciplinary integration across scientific branches. (shrink)

Philosophical dialogue has the power to improve interdisciplinary scientific research. The Toolbox Dialogue Initiative (TDI) conducts workshops that foster philosophical dialogue among interdisciplinary researchers. This chapter focuses on 20 of these workshops, all of which used the Toolbox STEM (Science, Technology, Engineering, and Mathematics) instrument and were conducted with interdisciplinary research teams of scientists. We analyze data from some of these workshops and demonstrate that philosophical dialogues conducted using the Toolbox method have two salutary effects. First, they lead to a (...) significant increase in belief formation about philosophical topics relevant to interdisciplinary science. Scientists sometimes do not have preconceived commitments on issues in philosophy of science, and Toolbox workshops tend to prompt them to adopt views on these topics. Second, these philosophical ….

We advance the understanding of the philosophy and psychology of curiosity by operationalizing and constructing an empirical measure of Nietzsche’s conception of inquisitive curiosity, expressed by the German term Wissbegier, (“thirst for knowledge” or “need/impetus to know”) and Neugier (“curiosity” or “inquisitiveness”). First, we show that existing empirical measures of curiosity do not tap the construct of inquisitive curiosity, though they may tap related constructs such as idle curiosity and phenomenological curiosity. Next, we map the concept of inquisitive curiosity and (...) connect it to related concepts, such as open-mindedness and intellectual humility. The bulk of the paper reports four studies: an Anglophone exploratory factor analysis, an Anglophone confirmatory factor analysis, an informant study, and a Germanophone exploratory and confirmatory factor analysis.

Intellectual humility is an interesting but underexplored disposition. The claim “I am (intellectually) humble” seems paradoxical in that someone who has the disposition in question would not typically volunteer it. There is an explanatory gap between the meaning of the sentence and the meaning the speaker expresses by uttering it. We therefore suggest analyzing intellectual humility semantically, using a psycholexical approach that focuses on both synonyms and antonyms of ‘intellectual humility’. We present a thesaurus-based method to map the semantic space (...) of intellectual humility as a heuristic to support philosophical and psychological analysis of this disposition. We find three semantic clusters that compose intellectual humility: the sensible self, the discreet self, and the inquisitive self; likewise, we find three clusters that compose its contraries: the overrated self, the underrated other, and the underrated self.

Research integrating the perspectives of different disciplines, or interdisciplinary research, has become increasingly common in academia and is considered important for its ability to address complex questions and problems. This mode of research aims to leverage differences among disciplines in generating a more complex understanding of the research landscape. To interact successfully with other disciplines, researchers must appreciate their differences, and this requires recognizing how the research landscape looks from the perspective of other disciplines. One central aspect of these disciplinary (...) perspectives involves values, and more specifically, the roles that values do, may, and should play in research practice. It is reasonable to think that disciplines differ in part because of the different views that their practitioners have on these roles. This paper represents a step in the direction of evaluating this thought. Operating at the level of academic branches, which comprise relevantly similar disciplines (e.g. social and behavioral sciences), this paper uses quantitative techniques to investigate whether academic branches differ in terms of views on the impact of values on research. Somewhat surprisingly, we find very little relation between differences in these views and differences in academic branch. We discuss these findings from a philosophical perspective to conclude the paper. (shrink)

Humility is a paradoxical virtue. This should come as no great surprise. It doesn’t take much explanation for one to realize that if someone is boasting about how humble he is, then he probably is not humble. In fact, as we shall see, the paradoxical nature of humility has a long history, going back to at least Thomas Aquinas in the thirteenth century. While it may not be a novel claim that there exists an apparent paradox of humility, I will (...) argue that there is more than one humility paradox, perhaps as many as five: the epistemic paradox, the paradox of self-attribution, the inculcation paradox, the agentic paradox, and the axiological paradox. All these paradoxes are distinct, yet seemingly intertwined. Upon examining them each in turn, we will be left with a Gordian knot of humility paradoxes. (shrink)

Intellectual humility can be broadly construed as being conscious of the limits of one’s existing knowledge and capable of acquiring more knowledge, which makes it a key virtue of the information age. However, the claim “I am humble” seems paradoxical in that someone who has the disposition in question would not typically volunteer it. Therefore, measuring intellectual humility via self-report may be methodologically unsound. As a consequence, we suggest analyzing intellectual humility semantically, using a psycholexical approach that focuses on both (...) synonyms and antonyms of ‘intellectual humility’. We present a thesaurus-based methodology to map the semantic space of intellectual humility and the vices it opposes as a heuristic to support analysis and diagnosis of this disposition. We performed the mapping both in English and German in order to test for possible cultural differences in the understanding of intellectual humility. In both languages, we find basically the same three semantic dimensions of intellectual humility as well as three dimensions of its related vices. The resulting semantic clusters were validated in an empirical study with English and German participants. We find medium-to-high correlations between thesaurus similarity and perceived similarity, and we can validate the three dimensions identified in the study. But we also find limitations of the thesaurus methodology in terms of cluster plausibility. We conclude by discussing the importance of these findings for constructing psychometric measures of intellectual humility via self-report vs. computer models. (shrink)

Review and response to Gimbel’s Isn’t That Clever.

We applaud the goals and execution of the target article, but note that individual differences do not receive much attention. This is a shortcoming because individual differences can play a vital role in theory testing. In our commentary, we describe programs of research of this type and also apply similar thinking to the mechanisms proposed in the target article.

In both lan- guages, we find basically the same three semantic dimensions of intellectual humility (sensi- bility, discreetness, and knowledge dimensions) as well as three dimensions of its related vic- es (self-overrating, other-underrating and dogmatism dimensions). The resulting semantic clusters were validated in an empirical study with English (n=276) and German (n=406) par- ticipants. We find medium to high correlations (0.54-0.72) between thesaurus similarity and perceived similarity, and we can validate the labels of the three dimensions identified in the study. But we also find indications of the limitations of the thesaurus methodology in terms of cluster plausibility. We conclude by discussing the importance of these findings for construct- ing psychometric scales for intellectual humility. (shrink)

What if philosophy, theology, and science spent a little more time together? These fields often seem at odds, butting metaphysical heads. Instead of talking at, how about talking with one another? This book engages three academic disciplines--distinct yet sharing much in common--in a slice of conversation and community in which participants have aimed at validating the other and the way the other sees the world. The result is a collection of essays united by a thread that can be hard to (...) find in academia. In bringing together a wide range of contributors on a project that at first seemed unlikely, Irreconcilable Differences? is also a testament to the spirit of cooperation and hard work--evidence that small acts and events can make a big difference, and that sometimes all you need in order to make something good happen is an idea with a little support along the way. The editors of this collection are hopeful that its contributors and readers will keep looking for ways to bridge academic, social, and political gaps. We need to forge relationships based on personal knowledge and proper confidence seeking to make meaningful claims in an increasingly complex world. (shrink)

Recent work in experimental philosophy has shown that people are more likely to attribute intentionality, knowledge, and other psychological properties to someone who causes a bad side effect than to someone who causes a good one. We argue that all of these asymmetries can be explained in terms of a single underlying asymmetry involving belief attribution because the belief that one’s action would result in a certain side effect is a necessary component of each of the psychological attitudes in question. (...) We argue further that this belief-attribution asymmetry is rational because it mirrors a belief-formation asymmetry, and that thebelief-formation asymmetry is also rational because it is more useful to form some beliefs than others.

This paper presents five studies on the development and validation of a scale of intellectual humility. This scale captures cognitive, affective, behavioral, and motivational components of the construct that have been identified by various philosophers in their conceptual analyses of intellectual humility. We find that intellectual humility has four core dimensions: Open-mindedness (versus Arrogance), Intellectual Modesty (versus Vanity), Corrigibility (versus Fragility), and Engagement (versus Boredom). These dimensions display adequate self-informant agreement, and adequate convergent, divergent, and discriminant validity. In particular, Open-mindedness (...) adds predictive power beyond the Big Six for an objective behavioral measure of intellectual humility, and Intellectual Modesty is uniquely related to Narcissism. We find that a similar factor structure emerges in Germanophone participants, giving initial evidence for the model’s cross-cultural generalizability. (shrink)

In this article, we describe a project in which philosophy, in combination with methods drawn from mental modeling, was used to structure dialogue among stakeholders in a region-scale climate adaptation process. The case study we discuss synthesizes the Toolbox dialogue method, a philosophically grounded approach to enhancing communication and collaboration in complex research and practice, with a mental modeling approach rooted in risk analysis, assessment, and communication to structure conversations among non-academic stakeholders who have a common interest in planning for (...) a sustainable future. We begin by describing the background of this project, including details about climate resiliency efforts in West Michigan and the Toolbox dialogue method, which was extended in this project from academic research into community organization involving the West Michigan Climate Resiliency Framework Initiative. This extension involved application of several methods, which are the focus of the Methods section. We then present and discuss preliminary results that suggest the potential for philosophical dialogue to enhance mutual understanding in complex community initiatives that focus on sustainable responses to climate change. Overall, the article supplies a detailed, instructive example of how philosophy can support policy-relevant decision-making processes at the community level. (shrink)

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

In lieu of an abstract, here is a brief excerpt of the content:The Sacrificial Ram and the Swan QueenMimetic Theory Fades to BlackBrian Collins (bio)“We speak of a ‘black’ mirror. But where it mirrors, it darkens, of course, but it doesn’t look black, and that which is seen in it does not appear ‘dirty’ but ‘deep.’”—Ludwig Wittgenstein, Remarks on ColorThis paper explores the ways in which male and female bodies become the sites of mimetic desire and ritual violence in Darren (...) Aronofsky’s two companion films The Wrestler (109 min, Wild Bunch, 2008, DVD) and Black Swan (108 min, Fox Searchlight, 2010, DVD). Both films (which were originally intended to be one film, explaining their thematic consistency)1 share three elements. First, both explore cultural forms, wrestling and dance, respectively, that punish the body of the performer in a spectacular way. Second, both films end with the ritualistic dying (if not the death) of the main character. Third, in both films, this dying is accompanied by a kind of transformation that can only be called “becoming-animal.”2 Though this last point is much easier to demonstrate [End Page 207] in the case of Black Swan, I will argue that this is also true for The Wrestler. In interpreting these films, I will rely mainly on René Girard’s ideas about mimetic desire and the surrogate victim mechanism, supplemented by Slavoj Žižek’s notion of symbolic death. Symbolic death or “second death” is Žižek’s Hegelian appropriation of the psychoanalytic death drive. The death drive holds a special place for Girard, since he considers Freud’s formulation of the death drive his admission that the Oedipal complex cannot explain the compulsion to repetition, an admission for which he credits Freud’s honesty. In this paper, I demonstrate that pseudo-masochism, Girard’s alternate theory of repetition, and the Žižekian second death are both present in Black Swan and The Wrestler, and that each film plays on the animal/human distinction and ritual transformations of the body to explore these themes.Part One: The Sacrificial Ram“The function of the wrestler is not to win: it is to go exactly through the motions which are expected of him.”—Roland Barthes, “The World of Wrestling,” MythologiesThe Pseudo-Masochistic Body I: Becoming-RamWilliam Golding’s novel Pincher Martin: The Two Deaths of Christopher Martin (London: Faber and Faber Limited, 1956) follows a bitter, selfish, and intransigent sailor who finds himself clinging to a rock in the middle of the ocean, the sole survivor of a shipwreck, only to slowly learn that he is not a survivor at all, but is rather trapped like a character from The Twilight Zone in the utter loneliness of the timeless time between his titular “two deaths.” The first death comes when Martin goes down with his ship and the second comes when he is annihilated (possibly; the ending is ambiguous) by the “black lightning,” which Terry Eagleton identifies in his analysis of the book as “the fire of God’s ruthless love, which burns up those who cannot bear it.” Martin’s misotheism is his last defense against the terrifying power of love, and he continues to defy God as the black lightning engulfs him.3 Why the two deaths? Martin is unable to die properly the first time, Eagleton argues, “because he is incapable of love. Only the good are capable of dying. Martin cannot yield himself up to death because he has never been able to yield himself up to others in life.”4 [End Page 208]Randy “The Ram” Robinson, born Robin Ramzinski, (Mickey Rourke), the protagonist of The Wrestler, is, like Pincher Martin, between two deaths, isolated from the rest of humanity because of his inability to connect with others. But while Pincher Martin is defiant and bound for a self-created Hell because of his deliberate rejection of love, Ram is a much more sympathetic character—though no less doomed—because he tries but fails time after time to accept the love of those who could save him. Pincher Martin’s self-created internal obstacle is his hatred of God, externalized through his encounter with the black lightning. But in Ram’s case... (shrink)

Authors have a lot of leeway with regard to what they can make true in their story. In general, if the author says that p is true in the fiction we’re reading, we believe that p is true in that fiction. And if we’re playing along with the fictional game, we imagine that, along with everything else in the story, p is true. But there are exceptions to these general principles. Many authors, most notably Kendall Walton and Tamar Szabó Gendler, (...) have discussed apparent counterexamples when p is “morally deviant”. Many other statements that are conceptually impossible also seem to be counterexamples. In this paper I do four things. I survey the range of counterexamples, or at least putative counterexamples, to the principles. Then I look to explanations of the counterexamples. I argue, following Gendler, that the explanation cannot simply be that morally deviant claims are impossible. I argue that the distinctive attitudes we have towards moral propositions cannot explain the counterexamples, since some of the examples don’t involve moral concepts. And I put forward a proposed explanation that turns on the role of ‘higher-level concepts’, concepts that if they are satisfied are satisfied in virtue of more fundamental facts about the world, in fiction, and in imagination.

We provide a new interpretation of Zeno’s Paradox of Measure that begins by giving a substantive account, drawn from Aristotle’s text, of the fact that points lack magnitude. The main elements of this account are (1) the Axiom of Archimedes which states that there are no infinitesimal magnitudes, and (2) the principle that all assignments of magnitude, or lack thereof, must be grounded in the magnitude of line segments, the primary objects to which the notion of linear magnitude applies. Armed (...) with this account, we are ineluctably driven to introduce a highly constructive notion of (outer) measure based exclusively on the total magnitude of potentially infinite collections of line segments. The Paradox of Measure then consists in the proof that every finite or potentially infinite collection of points lacks magnitude with respect to this notion of measure. We observe that the Paradox of Measure, thus understood, troubled analysts into the 1880’s, despite their knowledge that the linear continuum is uncountable. The Paradox was ultimately resolved by Borel in his thesis of 1893, as a corollary to his celebrated result that every countable open cover of a closed line segment has a finite sub-cover, a result he later called the “First Fundamental Theorem of Measure Theory.” This achievement of Borel has not been sufficiently appreciated. We conclude with a metamathematical analysis of the resolution of the paradox made possible by recent results in reverse mathematics. (shrink)

Normative Externalism argues that it is not important that people live up to their own principles. What matters, in both ethics and epistemology, is that they live up to the correct principles: that they do the right thing, and that they believe rationally. This stance, that what matters are the correct principles, not one's own principles, has implications across ethics and epistemology. In ethics, it undermines the ideas that moral uncertainty should be treated just like factual uncertainty, that moral ignorance (...) frequently excuses moral wrongdoing, and that hypocrisy is a vice. In epistemology, it suggests we need new treatments of higher-order evidence, and of peer disagreement, and of circular reasoning, and the book suggests new approaches to each of these problems. Although the debates in ethics and in epistemology are often conducted separately, putting them in one place helps bring out their common themes. One common theme is that the view that one should live up to one's own principles looks less attractive when people have terrible principles, or when following their own principles would lead to riskier or more aggressive action than the correct principles. Another common theme is that asking people to live up to their principles leads to regresses. It can be hard to know what action or belief complies with one's principles. And now we can ask, in such a case should a person do what they think their principles require, or what their principles actually require? Both answers lead to problems, and the best way to avoid these problems is to simply say people should follow the correct principles. (shrink)

We use a public-good experiment to analyze behavior in a decentralized asymmetric punishment institution. The institution is asymmetric in the sense that players differ in the effectiveness of their punishment. At the aggregate level, we observe remarkable similarities between outcomes in asymmetric and symmetric punishment institutions. Controlling for the average punishment effectiveness of the institutions, we find that asymmetric punishment institutions are as effective in fostering cooperation and as efficient as symmetric institutions. At the individual level, we find that players (...) with higher punishment effectiveness contribute similar amounts to the public account, but have higher earnings and punish more than their weak counterparts.
