Female crested gibbons (genus Nomascus) perform conspicuous sequences of twitching movements involving the rump and extremities. However, these dances have attracted little scientific attention and their structure and meaning remain largely obscure. Here we analyse close-range video recordings of captive crested gibbons, extracting descriptions of dance in four species (N. annamensis, N. gabriellae, N. leucogenys and N. siki). In addition, we report results from a survey amongst relevant professionals clarifying behavioural contexts of dance in captive and wild crested gibbons. Our (...) results demonstrate that dances in Nomascus represent a common and intentional form of visual communication restricted to sexually mature females. Whilst primarily used as a proceptive signal to solicit copulation, dances occur in a wide range of contexts related to arousal and/or frustration in captivity. A linguistically informed view of this sequential behaviour demonstrates that movement within dances is organized in groups and follows an isochronous rhythm — patterns not described for visual displays in other non-human primates. We argue that applying the concept of dance to gibbons allows us to expand our understanding of communication in non-human primates and to develop hypotheses on the rules and regularities characterising it. We propose that crested gibbon dances likely evolved from less elaborate rhythmic proceptive signals, similar to those found in siamangs. Although dance displays in humans and crested gibbons share a number of key characteristics, they cannot be assumed to be homologous. Nevertheless, gibbon dances represent a striking model behaviour to investigate the use of complex gestural signals in hominoid primates. (shrink)

The eponymous dialogue presents the sophist as a figure who defies definition, and those difficulties are attributed to the conception of the image. Ultimately, the sophist is defined as a species of image maker. The image, however, which is important throughout the Platonic corpus as a metaphor, an analogy, and a metaphysical concept as well, receives in the Sophist little clarification or definition apart from whatever may be inferred from the division of image making arts. In the Sophist, the sophist (...) escapes definition as in no other dialogue, rendering even the concluding division one that makes the distinction of the sophist from the philosopher problematic, if not impossible. The paper explores how the dialogue problematizes and rethinks the metaphysics of the image, as compared to its use in dialogues such as the Phaedo and the Republic, pointing to a refinement in understanding the relation of judgment to knowledge and appearance to reality.

*As mentioned in Peter Coy's NYT essay "When Being Good Is Just a Matter of Being Lucky" (2023) -/- ----- -/- How is the problem of free will related to the problem of moral luck? In this essay, I answer that question and outline a new solution to the paradox of moral luck, the source-paradox solution. This solution both explains why the paradox arises and why moral luck does not exist. To make my case, I highlight a few key connections (...) between the paradox of moral luck and two related problems, namely the problem of free will and determinism and the paradox of self-creation. Piecing together intuitions, arguments, and insights from recent work on each of these three problems, I argue that the type of control necessary for moral responsibility can only be had by someone who is a genuine source of his own actions, but the relevant notion of sourcehood admits no coherent characterization. If our commonsense view of moral responsibility is incoherent, it is unsurprising that our commitment to the existence of morally responsible agents commits us to some paradoxical things—e.g. to both the existence and impossibility of moral luck.

In her Descartes Lectures, Cheshire Calhoun argues that “responsible person” is a valuable cross-temporal status assigned by default to fellow social participants. Responsible persons, on Calhoun’s proposal, are (i) accountable, (ii) compliant with at least basic normative expectations, and (iii) disposed to take responsibility—to promote good ends in ways that are not normatively expected. The third component in particular goes beyond what is standardly discussed in debates about moral responsibility, where the relation to what is normatively expected is central. (...) In the main part of my commentary, I outline what I take to underlie normative expectations related to predictively expected acts of promoting good ends. These normative expectations are structured by pro tanto obligations to help, by evaluative autonomy, and by what I call “balancing norms,” which call on us to care about giving people and certain other values a certain comparative weight over time. Once we take this structure into account, I suggest, it is doubtful that people are assumed by default to be responsibility takers in Calhoun’s sense: what we predictively expect is also normatively expected. In addition, I propose a way of nevertheless making good on Calhoun’s suggestion that accountability, compliance responsibility, and contributions to the common good that merit gratitude are all aspects of responsibility. Finally, I suggest that what positive reactive attitudes reveal about their targets is not that they are responsibility takers, but that they are weight-givers subject to balancing norms. (shrink)

On a now orthodox view, humans and many other animals possess a “number sense,” or approximate number system, that represents number. Recently, this orthodox view has been subject to numerous critiques that question whether the ANS genuinely represents number. We distinguish three lines of critique – the arguments from congruency, confounds, and imprecision – and show that none succeed. We then provide positive reasons to think that the ANS genuinely represents numbers, and not just non-numerical confounds or exotic substitutes for (...) number, such as “numerosities” or “quanticals,” as critics propose. In so doing, we raise a neglected question: numbers of what kind? Proponents of the orthodox view have been remarkably coy on this issue. But this is unsatisfactory since the predictions of the orthodox view, including the situations in which the ANS is expected to succeed or fail, turn on the kind of number being represented. In response, we propose that the ANS represents not only natural numbers, but also non-natural rational numbers. It does not represent irrational numbers, however, and thereby fails to represent the real numbers more generally. This distances our proposal from existing conjectures, refines our understanding of the ANS, and paves the way for future research. (shrink)

The standard view about sex differences in sexual desire is that males are lusty and loose, while females are cool and coy. This is widely believed and is a core premise of some scientific programs like evolutionary psychology. But is it true? A mountain of evidence seems to support the standard view. Yet, this evidence is shot through with methodological and philosophical problems. Developments in the study of sexual desire suggest that some of these problems can be resolved, and when (...) they are, the standard view looks, at best, to be an exaggeration. (shrink)

The deaths of those on whom our practical identities rely generate a sense of disorientation or alienation from the world seemingly at odds with life being meaningful. In the terms put forth in Cheshire Calhoun’s recent account of meaningfulness in life, because their existence serves as a metaphysical presupposition of our practical identities, their deaths threaten to upend a background frame of agency against which much of our choice and deliberation takes place. Here I argue for a dual role (...) for grief in addressing this threat to life’s meaningfulness. Inasmuch as grief’s object is the loss of our relationship with the deceased as it was prior to their death, grief serves to alert us to the threat to our practical identities that their deaths pose to us and motivates us to defuse this threat by revising our practical identities to reflect the modification in our relationship necessitated by their deaths. Simultaneously, the emotional complexity and richness of grief episodes provides an abundance of normative evidence regarding our relationship with the deceased and our practical identities, evidence that can enable us to re-establish our practical identities and thereby recover a sense of our lives as meaningful.

A wide body of psychological research corroborates the claim that whether one’s life is (or will be) meaningful appears relevant to whether it is rational to continue living. This article advances conceptions of life’s meaningfulness and of suicidal choice with an eye to ascertaining how the former might provide justificatory reasons relevant to the latter. Drawing upon the recent theory of meaningfulness defended by Cheshire Calhoun, the decision to engage in suicide can be understood as a choice related to (...) life’s meaningfulness insofar as an individual can see no point in investing her agency in her anticipated future. These meaning-based reasons relevant to suicidal choice either cannot be reduced to the reasons of well-being that philosophers have typically used to analyse suicide decisions or at least forms a distinct class of reasons within those that contribute to well-being.

Suppose Alice asserts p, and the Caterpillar wants to disagree. If the Caterpillar accepts classical logic, he has an easy way to indicate this disagreement: he can simply assert ¬p. Sometimes, though, things are not so easy. For example, suppose the Cheshire Cat is a paracompletist who thinks that p ∨ ¬p fails (in familiar (if possibly misleading) language, the Cheshire Cat thinks p is a gap). Then he surely disagrees with Alice's assertion of p, but should himself (...) be unwilling to assert ¬p. So he cannot simply use the classical solution. Dually, suppose the Mad Hatter is a dialetheist who thinks that p ∧ ¬p holds (that is, he thinks p is a glut). Then he may assert ¬p, but it should not be taken to indicate that he disagrees with Alice; he doesn't. So he too can't use the classical solution. The Cheshire Cat and the Mad Hatter, then, have a common problem, and philosophers with opinions like theirs have adopted a common solution to this problem: appeal to denial. Denial, these philosophers suppose, is a speech act like assertion, but it is not to be understood as in any way reducing to assertion. Importantly, denial is something different from the assertion of a negation; this is what allows it to work even in cases where assertion of negation does not. Just as importantly, denial must express disagreement, since this is the job it's being enlisted to do. (shrink)

No two individuals with the autism diagnosis are ever the same—yet many practitioners and parents can recognize signs of ASD very rapidly with the naked eye. What, then, is this phenotype of autism that shows itself across such distinct clinical presentations and heterogeneous developments? The “signs” seem notoriously slippery and resistant to the behavioral threshold categories that make up current assessment tools. Part of the problem is that cognitive and behavioral “abilities” typically are theorized as high-level disembodied and modular functions—that (...) are assessed discretely (impaired, normal, enhanced) to define a spectral syndrome. Even as biology reminds us that organic developing bodies are not made up of independent switches, we remain often seduced by the simplicity of mechanistic and cognitive models. Developmental disorders such as autism have accordingly been theorized as due to different modular dysfunctions—typically of cortical origin, i.e., failures of “theory of mind” (Baron-Cohen et al., 1985), of the “mirror neuron system” (Ramachandran and Oberman, 2006), of “weak central coherence” (Happe and Frith, 2006) or of the balance of “empathizing” and “systemizing” (Baron-Cohen, 2009), just to list a few. -/- The broad array of autonomic (Ming et al., 2005; Cheshire, 2012) and sensorimotor (Damasio and Maurer, 1978; Maurer and Damasio, 1982; Donnellan and Leary, 1995; Leary and Hill, 1996; Donnellan and Leary, 2012; Donnellan et al., 2012) differences experienced and reported by people with autism have by such theories typically been sidelined as “co-morbidities,” possibly sharing genetic causes, but rendered as incidental and decisively behaviorally irrelevant symptoms—surely disconnected from cognition. But what if the development of cortically based mental processes and autonomous control relies on the complexities and proper function of the peripheral nervous systems? Through such an “embodied” lens the heterogeneous symptoms of autism invites new interpretations. We propose here that many behavioral-level findings can be re-defined as downstream effects of how developing nervous systems attempt to cope and adapt to the challenges of having various noisy, unpredictable, and unreliable peripheral inputs.

This paper makes two essential claims about the nature of shame and shame punishment. I argue that, if we properly understand the nature of shame, that it is sometimes justifiable to shame others in the context of a pluralistic multicultural society. I begin by assessing the accounts of shame provided by Cheshire Calhoun (2004) and Julien Deonna, Raffaele Rodogno, & Fabrice Teroni (2012). I argue that both views have problems. I defend a theory of shame and embarrassment that connects (...) both emotions to “whole-self” properties. Shame and embarrassment, I claim, are products of the same underlying emotion. I distinguish between moralized and nonmoralized shame in order to show when, and how, moral and non-moral shame may be justly deployed. Shame is appropriate, I argue, if and only if it targets malleable moral or non-moral normative imperfections of a person’s ‘whole-self.’ Shame is unjustifiable when it targets durable aspects of a person’s “whole-self.” I conclude by distinguishing shame punishments from guilt punishments and show that my account can explain why it is wrong to shame individuals on account of their race, sex, gender, or body while permitting us to sometimes levy shame and shame punishment against others, even those otherwise immune to moral reasons.

In this short essay, I report results from a representative national dataset from the Cooperative Institutional Research Program that shows that significantly more men than women intend to major in philosophy at the high-school and pre-university level. This lends credence to pre-university effects hypotheses of women's underrepresentation in philosophy and successfully replicates a smaller analysis performed by Cheshire Calhoun at Colby College in 2009. I also defend my analysis against an objection that claims that intention to major is not (...) a good predictor of final major selection. Finally, I argue that this new analysis should lead to further investment in university-level diversity programs. (shrink)
