Caleb Ward interviews Black feminist writer, poet, educator, organizer, and scholar Alexis Pauline Gumbs about Audre Lorde’s spirituality, her ecological political praxis, her pedagogy, and the cross-generational scale of social change.

Discussions of sexual ethics often focus on the wrong of treating another as a mere object instead of as a person worthy of respect. On this view, the task of sexual ethics becomes putting the other’s subjectivity above their status as erotic object so as to avoid the harms of objectification. Ward and Anderson argue that such a view disregards the crucial, moral role that erotic objecthood plays in sexual encounters. Important moral features of intimacy are disclosed through the (...) experience of being an erotic object for another, as well as in perceiving another as an erotic object. Drawing on phenomenology, especially the insights of Simone de Beauvoir, Ward and Anderson argue that erotic encounters are shaped by the human condition of ambiguity, where being an object for others is intertwined with bodily agency. Because sexual agency is complex in this way, theories of sexual ethics and responsibility must widen their focus beyond transparent communication and authoritative expressions of will. (shrink)

Some theories of goodness are descriptively rich: they have much to say about what makes things good. Neo-Aristotelian accounts, for instance, detail the various features that make a human being, a dog, a bee good relative to facts about those forms of life. Famously, such theories of relative goodness tend to be comparatively poor: they have little or nothing to say about what makes one kind of being better than another kind. Other theories of goodness—those that take there to be (...) absolute goodness—are comparatively rich: they offer grounds for judging some types of things better than others because they have more absolute goodness. Moorean accounts, for example, can tell us that humans and human experiences are superior to bees and blades of grass. But such theories tend to be descriptively poor: they struggle to tell us in virtue of what this is so. In this essay we motivate and flesh out a view that splits the difference between accounts of goodness as relative and accounts of goodness as absolute. Such a view holds promise only if the mechanics of this kind of metaphysics of goodness can be worked out. Here we present a view on which the paradigm for absolute goodness is God and the paradigm for each kind of relative goodness is a divine idea. (shrink)

Cissexist perception involves a prejudicial judgment and an unmediated affective response, such as that of disgust, directed at the gendered aspects of another person. In this paper, I advance a view of how cissexist perception harms disabled people. On this view, there at least two morally problematic aspects of cissexist perception: that it has painful effects, and that it restricts bodily agency. I defend this claim through an analysis of a double bind faced by people subjected to cissexist perception: on (...) the one hand, such individuals are pressured into avoiding certain environments to dodge dangerous predicaments that can arise on behalf of looking different from others; this constitutes unfair exclusion from an environment and under some conditions causes pain. On the other hand, to avoid dangerous predicaments, targets of cissexist perception are pressured into concealing their gender non-conformity to fit into certain environments; concealing frustrates their bodily agency. I conclude with remarks about how trans-affirming artwork may have the capacity to interrupt cissexist perception. (shrink)

Defense of a psychological account of what it is for an artwork to be complete.

Scientific hedges are communicative devices used to qualify and weaken scientific claims. Gregor Betz has argued—unconvincingly, we think—that hedging can rescue the value-free ideal for science. Nevertheless, Betz is onto something when he suggests there are political principles that recommend scientists hedge public-facing claims. In this article, we recast this suggestion using the notion of public justification. We formulate and reject a Rawlsian argument that locates the justification for hedging in its ability to forge consensus. On our alternative proposal, hedging (...) is often justified because it renders scientific claims as publicly accessible reasons. (shrink)

A popular argument for a right to ectogenic abortions appeals to a right to avoid the obligations associated with parenthood. A common objection to this argument questions whether there are any sufficiently great harms associated with parenthood to ground such a right. I propose a novel formulation of this argument that avoids these objections. I then defend it against important objections.

Clinical psychology is characterized by persistent disagreement about fundamental aspects of the discipline ranging from what mental disorders are to what constitutes effective treatment. Attempts to address the problem of epistemic disagreement have been frequently based on establishing the correct answer by fiat without identifying and addressing the sources of the disagreement. We argue that this strategy has not worked very well and the result is frequently ongoing and intractable disagreement, with each side in an argument convinced they are correct. (...) In this paper, we outline an epistemic disagreement procedural model intended to assist researchers and clinicians in the field of clinical psychology to identify, explore, and develop inquiry strategies that capitalize on situations where competing knowledge claims are made. The result is a flexible conceptual framework committed to a defensible epistemic pluralism, fallibilism, and contextualism, across the various research tasks constituting the field of clinical psychology.

Despite the growing attention to oppression and resistance in social and political philosophy as well as ethics, philosophers continue to struggle to describe and appropriately attribute agency under non-ideal circumstances of oppression and structural injustice. This chapter identifies some features of new accounts of non-ideal agency and then examines a particular problem for such theories, what Serene Khader has called the agency dilemma. Under the agency dilemma, attempts to articulate the agency of subjects living under oppression must on the one (...) hand avoid overemphasizing constraints on agency, and thereby producing paternalistic theories that “deny agency” for oppressed subjects, and on the other hand avoid failing to fully appreciate the effects of oppression on agency, thereby missing crucial features of how oppression unjustly shapes a person’s lived possibilities. This chapter traces this dilemma to a preoccupation with ascribing agency, which produces problematic descriptive and political effects for theorizing agency under oppression: what the author calls an asymmetry problem and a disenfranchisement problem. Finally, the chapter proposes that the agency dilemma might be ameliorated if theorists scrutinize more closely how moral, epistemic, and political agency interact and overlap in life under oppression.

Defense of incompletable grounding and discussion of implications for ontological economy.

This introduction to a special issue of Topoi introduces and summarises the relationship between three main varieties of 'enactivist' theorising about the mind: 'autopoietic', 'sensorimotor', and 'radical' enactivism. It includes a brief discussion of the philosophical and cognitive scientific precursors to enactivist theories, and the relationship of enactivism to other trends in embodied cognitive science and philosophy of mind.

General discussion of grounding, including its formal features, relations to other notions, and applications.

If there is to be any progress in the debate about what sort of positive moral status Kant can give the emotions, we need a taxonomy of the terms Kant uses for these concepts. It used to be thought that Kant had little room for emotions in his ethics. In the past three decades, Marcia Baron, Paul Guyer, Barbara Herman, Nancy Sherman, Allen Wood and others have argued otherwise. Contrary to what a cursory reading of the Groundwork may indicate, Kant (...) thinks the emotions play an important role in the moral life. I want to extend the work of Baron, Guyer, Herman, Sherman and Wood in three ways. First, I will set out in a diagram Kant's taxonomy of feelings and emotions. Agreement on such a taxonomy should make it easier to evaluate debates about Kant and the emotions. Second, I will focus on a certain subclass of emotions – reason-caused affects – that have previously received little attention, even from these Kant scholars. Third, these scholars base much of their defence of Kant on his later works – especially the Metaphysics of Morals and the Anthropology – but Kant's fairly rich taxonomy of the emotions, including reason-caused affects, is clearly in place at least as early as the Critique of Judgment . I believe that the Critique of Judgment is an importantly ignored resource for understanding the moral role of the emotions for Kant. The third Critique makes positive, philosophically interesting claims about the emotions and morality. Kant emphasizes certain roles for emotions in this work that he develops to the same extent nowhere else. Nevertheless, the Critique of Judgment goes all but unmentioned by many who write on these issues. In what follows, I will defend as many of my claims as possible using the third Critique. (shrink)

Response to Skiles (2009) on Trogdon (2009) on intrinsic properties and fundamentality.

Audre Lorde’s account of the erotic is one of her most widely celebrated contributions to political theory and feminist activism, but her explanation of the term in her brief essay “Uses of the Erotic” is famously oblique and ambiguous. This article develops a detailed, textually grounded interpretation of Lorde’s erotic, based on an analysis of how Lorde’s essay brings together commitments expressed across her work. I describe four integral elements of Lorde’s erotic: feeling, knowledge, power, and concerted action. The erotic (...) is a way of feeling in the work a person does, which makes possible new knowledge about the self and the social environment— particularly to counteract epistemic oppression imposed by an unjust society. The erotic is a source of power by providing vision and energy for actions integrating a person’s multiple commitments and political interests. It facilitates concerted action and coalition by enhancing a person’s appreciation of their interests and values, while fostering embodied, personal connections that build trust on the basis of shared vulnerability. Thus, the erotic helps build coalitions where genuine differences of perspective and experience can be examined, in resistance against an oppressive society’s epistemic distortions. (shrink)

Throughout her work, Audre Lorde maintains that her self-preservation in the face of oppression depends on acting from the recognition and valorization of her feelings as a deep source of knowledge. This claim, taken as a portrayal of agency, poses challenges to standard positions in ethics, epistemology, and moral psychology. This article examines the oppositional agency articulated by Lorde’s thought, locating feeling, poetry, and the power she calls “the erotic” within her avowed project of self-preservation. It then explores the implications (...) of taking seriously Lorde’s account, particularly for theorists examining ethics and epistemology under nonideal social conditions. For situations of sexual intimacy, for example, Lorde’s account unsettles prevailing assumptions about the role of consent in responsibility between sexual partners. I argue that obligations to solicit consent and respect refusal are not sufficient to acknowledge the value of agency in intimate encounters when agency is oppositional in the way Lorde describes.

Argument that full grounds modally entail what they ground.

Characterization of a form of explanation involving grounding on the model of mechanistic causal explanation.

Discussion of partial grounds that aren't parts of full grounds; definition of full grounding in terms of partial grounding.

Our primary aim in this paper is to sketch a cognitive evolutionary approach for developing explanations of social change that is anchored on the psychological mechanisms underlying normative cognition and the transmission of social norms. We throw the relevant features of this approach into relief by comparing it with the self-fulfilling social expectations account developed by Bicchieri and colleagues. After describing both accounts, we argue that the two approaches are largely compatible, but that the cognitive evolutionary approach is well- suited (...) to encompass much of the social expectations view, whose focus on a narrow range of norms comes at the expense of the breadth the cognitive evolutionary approach can provide.

Argument that priority monism is best understood as being a contingent thesis.

Discussion of the challenge that acquaintance with the nature of experience poses to physicalism.

Most psychological research aims to uncover generalizations about the mind that hold across subjects. Philosophical discussions of scientific explanation have focused on such generalizations, but in doing so, have often overlooked an important phenomenon: variation. Variation is ubiquitous in psychology and many other domains, and an important target of explanation in its own right. Here I characterize explananda that concern individual differences and formulate an account of what it takes to explain them. I argue that the notion of actual difference (...) making, the only causal concept in the literature that explicitly addresses variation, cannot be used to ground such an account. Instead, I propose a view on which explaining individual differences involves identifying causes that could be intervened on to reduce the variability in the population. This account provides criteria of success for explaining variation and deepens our understanding of causal explanation. (shrink)

The Swiss psychologist Jean Piaget contends that children below the age of 12 see no necessity for the logical law of non-contradiction. I argue this view is problematic. First of all, Piaget's dialogues with children which are considered supportive of this position are not clearly so. Secondly, Piaget underestimates the necessary nature of following the logical law of non-contradiction in everyday discourse. The mere possibility of saying something significant and informative at all presupposes that the law of non-contradiction is enforced.

Discussion of a metaphysical sense of 'inheritance' and cognate notions relevant to fundamentality.

A large chorus of voices has grown around the claim that theistic belief is epistemically suspect since, as some cognitive scientists have hypothesized, such beliefs are a byproduct of cognitive mechanisms which evolved for rather different adaptive purposes. This paper begins with an overview of the pertinent cognitive science followed by a short discussion of some relevant epistemic concepts. Working from within a largely Williamsonian framework, we then present two different ways in which this research can be formulated into an (...) argument against theistic belief. We argue that neither version works. (shrink)

We present a specific elaboration and partial defense of the claims that cognition is enactive, embodied, embedded, affective and (potentially) extended. According to the view we will defend, the enactivist claim that perception and cognition essentially depend upon the cognizer’s interactions with their environment is fundamental. If a particular instance of this kind of dependence obtains, we will argue, then it follows that cognition is essentially embodied and embedded, that the underpinnings of cognition are inextricable from those of affect, that (...) the phenomenon of cognition itself is essentially bound up with affect, and that the possibility of cognitive extension depends upon the instantiation of a specific mode of skillful interrelation between cognizer and environment. Thus, if cognition is enactive then it is also embodied, embedded, affective and potentially extended. (shrink)

The idea that the brain is a representational organ has roots in the nineteenth century, when neurologists began drawing conclusions about what the brain represents from clinical and experimental studies. One of the earliest controversies surrounding representation in the brain was the “muscles versus movements” debate, which concerned whether the motor cortex represents complex movements or rather fractional components of movement. Prominent thinkers weighed in on each side: neurologists John Hughlings Jackson and F.M.R. Walshe in favor of complex movements, neurophysiologist (...) Charles Sherrington and neurosurgeon Wilder Penfield in favor of movement components. This essay examines these and other brain scientists’ evolving notions of representation during the first eighty years of the muscles versus movements debate (c. 1873–1954). Although participants agreed about many of the superficial features of representation, their inferences reveal deep-seated disagreements about its inferential role. Divergent epistemological commitments stoked conflicting conceptions of what representational attributions imply and what evidence supports them. (shrink)

Amendment of the Witmer, Butchard, and Trogdon (2005) account of intrinsic properties with the aim of neutrality between competing theories of what is fundamental.

Experiences of embodied remembering are familiar and diverse. We settle bodily into familiar chairs or find our way easily round familiar rooms. We inhabit our own kitchens or cars or workspaces effectively and comfortably, and feel disrupted when our habitual and accustomed objects or technologies change or break or are not available. Hearing a particular song can viscerally bring back either one conversation long ago, or just the urge to dance. Some people explicitly use their bodies to record, store, or (...) cue memories. Others can move skilfully, without stopping to think, in complex and changing environments thanks to the cumulative expertise accrued in their history of fighting fires, or dancing, or playing hockey. The forms of memory involved in these cases may be distinct, operating at different timescales and levels, and by way of different mechanisms and media, but they often cooperate in the many contexts of our practices of remembering.

There is strong disagreement about whether indicative conditionals have truth values. In this paper, I present a new argument for the conclusion that indicative conditionals have truth values based on the claim that some true statements entail indicative conditionals. I then address four arguments that conclude that indicative conditionals lack truth values, showing them to be inadequate. Finally, I present further benefits to having a worldly view of conditionals, which supports the assignment of truth values to indicative conditionals. I conclude (...) that certain types of account of indicative conditionals, which have been ignored in the literature partly on the basis of assigning truth values to indicative conditionals, deserve consideration.

We argue that a modified version of Mill’s method of agreement can strongly confirm causal generalizations. This mode of causal inference implicates the explanatory virtues of mechanism, analogy, consilience, and simplicity, and we identify it as a species of Inference to the Best Explanation (IBE). Since rational causal inference provides normative guidance, IBE is not a heuristic for Bayesian rationality. We give it an objective Bayesian formalization, one that has no need of principles of indifference and yields responses to the (...) Voltaire objection, van Fraassen’s Bad Lot objection, and John Norton’s recent objection to IBE. (shrink)

This paper presents a comprehensive analysis of the SEIRS COVID-19 pandemic model with saturated incidence rate. By modifying the existing model and proposing a new simplified version, we investigate the dynamics of disease transmission, including the impact of saturation terms on disease spread. Through stability analysis at disease-free and endemic equilibria, we aim to enhance understanding of the spread of COVID-19 and inform effective control strategies. Drawing on mathematical models and epidemiological insights, this study contributes to the ongoing efforts to (...) combat the global pandemic. (shrink)

How should accounts that stress the embodied, embedded and engaged character of human minds accommodate the role of rationality in human subjectivity? Drawing on Matthew Boyle’s contrast between ‘additive’ and ‘transformative’ conceptions of rationality, I argue that contemporary work on embodied cognition tends towards a problematic ‘additivism’ about the relationship between mature human capacities to think and act for reasons, and sensorimotor capacities to skillfully engage with salient features of the environment. Additivists view rational capacities to reason and reflect as (...) a distinct ‘layer’ or ‘storey’ of human cognition, with a normative structure that differs from that of the sensorimotor coping skills which support it. I argue that emphasizing the embodied and engaged character of human minds is better combined with a ‘transformative’ conception of rationality – one which holds that acquiring abilities to give and ask for reasons transforms the normative structure of our unreflective embodied dealings with the environment. And I argue that a transformative embodied cognitive science of human rationality is not only possible, but underway. Integrating existing work on embodied cognition with work on the cultural and developmental contexts that shape human minds suggests how human immersion in culture transforms the structure of sensorimotor engagements by bringing about the communicability and negotiability of the meanings to which those engagements attune us.

My modest aim in this piece is to frame and illuminate some of the issues surrounding normative motivation, rather than take a firm position on any of them.

In this short essay I will not be able to properly develop and evaluate an argument for the view that (...) normative motivations are psychologically primitive, but I will have some comments about what such an argument might look like, and what it would have to show.

Investigation of a puzzle concerning complete yet authorless artworks.

Clinical ethics consultants (CECs) are not moral authorities. Standardization of CECs’ professional role does not confer upon them moral authority. Certification of particular CECs does not confer upon them moral authority (nor does it reflect such authority). Or, so we will argue. This article offers a distinctly Orthodox Christian response to those who claim that CECs—or any other academically trained bioethicist—retain moral authority (i.e., an authority to know and recommend the right course of action). This article proceeds in three parts. (...) First, we discuss recent movements toward the certification of CECs in the United States, focusing primarily on proposals and programs put forth by the American Society for Humanities and Bioethics (ASBH). Second, we outline two secular reasons to be concerned about the relevant trends toward certification. For one thing, certification is currently being advanced via political dominance, rather than gaining authority by reliance on rigorous philosophical argument or reason. For another, the trends operate on the assumption that there exists a secular, content-full, canonical, morality. There is no such morality. Next, we argue that Orthodox Christians should resist the current trends toward certification of CECs. Specifically, we unpack ways in which the ASBH’s certification program (and those like it) conflict with Orthodox claims about moral authority and the moral life more generally. We conclude that Orthodox Christians should resist the current certification trends. (shrink)

Grounding-theoretic account of the notion of transparency relevant to the explanatory gap between the mental and physical.

Our in-the-moment experience of the world can feel vivid and rich, even when we cannot describe our experience due to limitations of attention, memory or other cognitive processes. But the nature of visual awareness is quite sparse, as suggested by the phenomena of failures of awareness, such as change blindness and inattentional blindness. I will argue that once failures of memory or failures of comparison are ruled out as explanations for these phenomena, they present strong evidence against rich awareness. To (...) accommodate and explain these massive failures of awareness, any theory of phenomenal consciousness must downgrade phenomenology to a degree where it is functionless or, ironically, does not reflect what we experience.

The phenomena of call-outs and call-ins are fiercely debated. Are they mere instances of virtue signaling? Or can they actually perform social justice work? This paper gains purchase on these questions by focusing on how language users negotiate norms in speech. The authors contend that norm-enacting speech not only makes a norm salient in a context but also creates conversational conditions that motivate adherence to that norm. Recognizing this allows us to define call-outs and call-ins: the act of calling-out brings (...) with it the presupposition that its target's behavior is norm-violating, whereas the act of calling-in simply presupposes its target's willingness to revise their belief. With these definitions at hand, we evaluate whether call-outs and call-ins are suitable tools for combating social injustice. (shrink)

Discussion of atomistic and monistic theses about abstract reality.

Grief research in philosophy agrees that one who grieves grieves over the irreversible loss of someone whom the griever loved deeply, and that someone thus factored centrally into the griever’s sense of purpose and meaning in the world. The analytic literature in general tends to focus its treatments on the paradigm case of grief as the death of a loved one. I want to restrict my account to the paradigm case because the paradigm case most persuades the mind that grief (...) is a past-directed emotion. The phenomenological move I propose will enable us to (1) respect the paradigm case of grief and a broader but still legitimate set of grief-generating states of affairs, (2) liberate grief from the view that grief is past directed or about the past, and thus (3) account for grief in a way that separates it from its closest emotion-neighbor, sorrow, without having to rely on the affective quality of those two emotions.If the passing of the beloved causes the grief but is not what the grief is about, then we can get at the nature of grief by saying its temporal orientation is in the past (the event of the passing), but its temporal meaning is the present and future—the new significance of a world with the pervasive absence that is the world without the beloved. The no-longer of grief is a no-longer oriented by a past (that which is no longer) that is referred a present and future (that which is a no-longer understood as not now as it once was). Looking at the griever’s relation to time can tell us much about the pain and the object of grief, then. As the griever puts the past before himself with a certainty about this world “henceforth,” a look at the griever’s lived sense of the fi nality of the irreversibly lost (1) liberates grief from the tendency in the literature to be reduced to a past-directed emotion, (2) accounts for grief ’s intensity, its affective force or poignancy, and thus (3) enables us to separate grief from sorrow according to its intentionalobject in light of the temporal meaning of these emotions.

In both popular and scholarly discussions, sexual consent is gaining traction as the central moral consideration in how people should treat one another in sexual encounters. However, while the concept of consent has been indispensable to oppose many forms of sexual violence, consent-based sexual ethics struggle to account for the phenomenological complexity of sexual intimacy and the social and structural pressures that often surround sexual communication and behavior. Feminist structural critique and social research on the prevalence of violation even within (...) consensual sex suggest that consent is insufficient to ground responsibility; a more fundamental orientation toward the value of sexual agency provides a better foundation for sexual ethics. Using feminist critical theory, phenomenology, and black feminist thought, this dissertation develops a socially situated and relational notion of sexual agency and diagnoses how such agency is neglected in prevailing discussions of consent in moral philosophy and legal theory. I argue that the ethical question of responsibility to another in a sexual encounter—apart from juridical considerations—should be reframed around the value of each person’s socially situated practices of agency. Preceding and extending beyond the obligation to gain valid consent for an action, responsibility demands adapting one’s intentions and behaviors in response to the wider range of another’s communicative expressions of agency. However, communicative expressions can be ambiguous or overdetermined by social context and cultural norms; they often offer only provisional traces of agency. To address this inherent uncertainty in intimacy, I propose drawing on insights from Emmanuel Levinas about the dynamic, open-ended nature of relationality, responsibility, and communication. Responsibility toward another does not depend on securing certainty about their “yes” or “no,” but requires responding continuously under conditions of uncertainty and ambiguity, adapting behaviors and intentions to make room for another’s agency despite its opacity.

Un fait Mooréen, selon l'expression de David Lewis, est « l'une des choses que nous savons mieux que toute prémisse d'une argumentation philosophique visant à é tablir le contraire. » Le sujet des faits Mooréens soulève des questions profondes, à la fois de méthode philosophique et d'épistémologie de premier ordre. Comment devrions-nous répondre aux arguments qui remettent en question des croyances dont nous sommes extrêmement confiants ? Dans quelle mesure ces arguments – ou plutôt ceux qui les avancent – peuvent-ils (...) espérer avoir une emprise ou une traction rationnelle sur nous ? Dans quelle mesure, si même c'est le cas, notre point de départ limite-t-il les types de révisions de nos croyances que la philosophie pourrait légitimement inspirer ? Quand sommes-nous justifiés (si jamais nous le sommes) à refuser de se laisser influencer par un argument qui, pour autant qu'on puisse en juger, est sans faille, et quand un tel refus relève-t-il simplement du dogmatisme ? Ce sont là de vastes questions, auxquelles je ne tenterai pas ici de répondre complétement.

Upshot: In our target article we claimed that, at least since Weber and Varela, enactivism has incorporated a theoretical commitment to one important aspect of Jonas’s philosophical biology, namely its anthropomorphism, which is at odds with the methodological commitments of modern science.

We do this by spelling out what we call the “Jonasian inference,” i.e., the idea that (...) we are entitled, based on our first-person experience of teleology, to take the appearance of teleology in other living beings at face value.

A dominant strand of philosophical thought holds that natural kinds are clusters of objects with shared properties. Cluster theories of natural kinds are often taken to be a late twentieth-century development, prompted by dissatisfaction with essentialism in philosophy of biology. I will argue here, however, that a cluster theory of kinds had actually been formulated by William Whewell (1794-1866) more than a century earlier. Cluster theories of kinds can be characterized in terms of three central commitments, all of which are (...) present in Whewell’s work on classification. Like contemporary cluster theorists, Whewell claims that kinds are united by similarity, that many kinds do not have essences, and that there are “gaps” between kinds. Moreover, Whewell advises taxonomists to look for consilience (roughly, convergence) between different classificatory schemes, a recommendation that reinforces the identification of natural classes with property clusters. Thus Whewell was not only an early cluster theorist, but one with important insights into what a cluster theory of kinds means for the practice of classification. (shrink)
