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.

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)

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. I begin by clarifying the key terms in my title of this essay, and unpacking some of the assumptions that underpin its question. I then distinguish four kinds of answers one might give. 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.

Argument that full grounds modally entail what they ground.

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)

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.

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

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

Being social creatures in a complex world, we do things together. We act jointly. While cooperation, in its broadest sense, can involve merely getting out of each other’s way, or refusing to deceive other people, it is also essential to human nature that it involves more active forms of collaboration and coordination (Tomasello 2009; Sterelny 2012). We collaborate with others in many ordinary activities which, though at times similar to those of other animals, take unique and diverse cultural and psychological (...) forms in human beings. But we also work closely and interactively with each other in more peculiar and flexible practices which are in distinctive ways both species-specific and culturally and historically contingent: from team sports to shared labour, from committee work to mass demonstrations, from dancing to reminiscing together about old times.

Discussion of grounding-theoretic accounts of truthmaking in terms of the theoretical role of “catching cheaters”.

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)

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)

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

Discussion of the relevance of grounding to substantiveness, theory-choice, and “location problems” in metaphysics.

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)

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. Mon ambition, plus modeste, est de tenter de progresser sur ces questions, et d'autres questions connexes, en examinant la notion de fait Mooré que je trouve chez Lewis et chez d'autres. (shrink)

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.

Addiction theorists have often utilized the metaphor of the blind men and the elephant to illustrate the complex nature of addiction and the varied methodological approaches to studying it. A common purported upshot is skeptical in nature: due to these complexities, it is not possible to offer a unifying account of addiction. I think that this is a mistake. The elephant is real–there is a _there_ there. Here, I defend a dispositionalist account of addiction as _the systematic disposition to fail (...) to control one’s desires to engage in certain types of behaviors_. I explain this position, defend the inclusion of desires and impaired control, and flesh out the notion of _systematicity_ central to my account. I then illustrate how my dispositionalist framework can unify the disparate and seemingly incompatible accounts of addiction (and their respective methodological approaches). I close with a brief plan to extend and implement my account. (shrink)

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

Charlotte Witt covers a remarkable amount of ground in this concise and elegantly written book. Coming in at under 150 pages, she artfully weaves together Aristotle’s theory of functions with contemporary work on cultural transmission and apprenticeship, ideas about self-creation with theories of aspiration and transformative experience, and reflections on the relationships among social norms and games with thoughts about social roles and the nature of hierarchy. At the heart of it is an elaboration and defense of a thoroughly externalist (...) account of social normativity. Witt takes skilled experts, especially artisans like chefs and carpenters, as paradigm cases for theorizing about social normativity. She uses them to argue that the ultimate source of many normative obligations is found not in the acquiescence, attitudes, or any other features internal to those on whom those obligations fall. Rather, the demands are rooted in the world itself, and flow from specific circumstances, especially from the constraints those circumstances impose on different actors in virtue of the tasks they need to perform. The result is a view that depicts social normativity not just as external to individuals but also unavoidably role specific; what is right for a chef is not necessarily right for a carpenter, and what makes for a good nurse might make for a poor drill sergeant. Witt’s presentation of this package of ideas is both careful and austere, and it makes for a wonderfully thought provoking read. Social Goodness: On the Ontology of Social Norms will reward the careful attention of anyone interested in social ontology, especially the metaphysical foundations of normativity, the nature of social norms, and the relationship between social roles and the self.

The intuitions at the core of environmental ethics and of other neglected value realms put pressure on traditional anthropocentric ethics based on monistic value theories. Such pressure is so severe that it has led many to give up on the idea of monistic value theories altogether. I argue that value monism is still preferable to value pluralism and that, indeed, these new challenges are opportunities to vastly improve impoverished traditional theories. I suggest an alternative monistic theory, Richness Theory, and show (...) how it provides an opportunity to capture the needs of both environmental ethics and of our traditional ethics. (shrink)

Grounding-theoretic reformulation of Fodor's theory of content that addresses recalcitrant Quinean concerns.

While those who take a "structuralist" approach to racial justice issues are right to call attention to the importance of social practices, laws, etc., they sometimes go too far by suggesting that antiracist efforts ought to focus on changing unjust social systems rather than changing individuals’ minds. We argue that while the “either/or” thinking implied by this framing is intuitive and pervasive, it is misleading and self-undermining. We instead advocate for a “both/and” approach to antiracist moral education that explicitly teaches (...) how social structures influence ideas about race and how ideas about race shape, sustain, and transform social structures. Ideally, antiracist moral education will help people see how social change and moral progress depend on the symbiotic relations between individuals and structures. We articulate a conception of “structure-facing virtue” that exemplifies this hybrid approach to illuminate the pivotal role moral education plays in the fight for racial justice. (shrink)

In this open peer commentary, we categorize the possible “neuroscience in national security” definitions of misuse of science and identify which, if any, are uniquely presented by advances in neuroscience. To define misuse, we first define what we would consider appropriate use: the application of reasonably safe and effective technology, based on valid and reliable scientific research, to serve a legitimate end. This definition presents distinct opportunities for assessing misuse: misuse is the application of invalid or unreliable science, or is (...) the use of reliable scientific methods to serve illegitimate ends. Ultimately, we conclude that while national security is often a politicized issue, assessing the state of scientific progress should not be. (shrink)

Rather than set out an overarching view or take a stand on the debunking of morality tout court, in what follows I’ll explore a divide and conquer strategy. First, I will briefly sketch a debunking argument that, instead of targeting all of morality or human moral nature, has a more narrow focus—namely, the intuitive moral authority of disgust. The argument concludes that as vivid and compelling as they can be while one is in their grip, feelings of disgust should be (...) granted no power to justify moral judgments. Importantly, the argument is grounded in empirical advances concerning the character of the emotion itself. Next, I will step back and consider the argument’s general form. I then point to arguments that others have made that seem to share this form and selective focus, and comment on what such arguments do and do not presuppose. Finally, I locate the selective strategy with respect to other approaches moral debunking. (shrink)

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.

Lack of consent is valorized within popular culture to the point that sexual assault has become a spectator sport and creepshot entertainment on social media. Indeed, the valorization of nonconsensual sex has reached the extreme where sex with unconscious girls, especially accompanied by photographs as trophies, has become a goal of some boys and men.

In May 2010, philosophers, family and friends gathered at the University of Notre Dame to celebrate the career and retirement of Alvin Plantinga, widely recognized as one of the world's leading figures in metaphysics, epistemology, and the philosophy of religion. Plantinga has earned particular respect within the community of Christian philosophers for the pivotal role that he played in the recent renewal and development of philosophy of religion and philosophical theology. Each of the essays in this volume engages with some (...) particular aspect of Plantinga's views on metaphysics, epistemology, or philosophy of religion. Contributors include Michael Bergman, Ernest Sosa, Trenton Merricks, Richard Otte, Peter VanInwagen, Thomas P. Flint, Eleonore Stump, Dean Zimmerman and Nicholas Wolterstorff.
