The evolution of color categorization systems is investigated by simulating categorization games played by a population of artificial agents. The constraints placed on individual agent’s perception and cognition are minimal and involve limited color discriminability and learning through reinforcement. The main dynamic mechanism for population evolution is pragmatic in nature: There is a pragmatic need for communication between agents, and if the results of such communications have positive consequences in their shared world then the agents involved are positively rewarded, whereas (...) if the results have negative consequences, then involved agents are punished. A mechanism for changing the composition of the population due to agents’ birth and death is also investigated. This birth-death mechanism is found to effectively move an established population color naming system toward a theoretically more optimal one. The simulation results of this article provide insights regarding mechanisms that may constrain universal tendencies in human color categorization systems observed in the linguistic and anthropological literatures.

This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were (...) higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students. (shrink)

In this paper I develop an account of member obligation: the obligations that fall on the members of an obligated collective in virtue of that collective obligation. I use this account to argue that unorganized collections of individuals can constitute obligated agents. I argue first that, to know when a collective obligation entails obligations on that collective’s members, we have to know not just what it would take for each member to do their part in satisfying the collective obligation, but (...) also what they should do if they cannot do their part because others will not do theirs. I go on to argue (contra recent proposals) that it is not good enough for members in this situation to reasonably believe that others will not do their part. Rather, for a member of an obligated collective to permissibly escape doing her part in a collective obligation, she must both reasonably doubt that others will do their part and stand ready to act in case others do as well. -/- This necessary condition for collective obligation points the way to plausible sufficient conditions – conditions that, I argue, allow unstructured collectives to bear obligations. For (a) if a collective’s members are individually obligated to be ready to do their part, in a given collective action, and (b) if that individual readiness makes it sufficiently likely that the collective will in fact act, then it is hard to see what could block an attribution of collective obligation. In particular, in that case there ought to be no additional objection that there is no existing, organized “agent” on which the obligation might fall. For agents are, simply, things that can act. To be able to act is just to be able to succeed by trying. Unstructured collectives try to do something, I argue, when each member acts on their willingness to do their part in that thing if others do theirs; sometimes they succeed, producing a collective action. Some unstructured collectives, therefore, can succeed by trying; therefore, they can act; therefore they are agents. (shrink)

What makes something a part of my body, for moral purposes? Is the body defined naturalistically: by biological relations, or psychological relations, or some combination of the two? This paper approaches this question by considering a borderline case: the status of prostheses. I argue that extant accounts of the body fail to capture prostheses as genuine body parts. Nor, however, do they provide plausible grounds for excluding prostheses, without excluding some paradigm organic parts in the process. I conclude by suggesting (...) that embodiment is moralized all the way down: to be a body part is to be the sort of thing that ought to be protected, in a certain way, by social practices. (shrink)

Emotional hardcore and other music genres featuring screamed vocals are puzzling for the appreciator. The typical fan attaches appreciative value to musical screams of emotional pain all the while acknowledging it would be inappropriate to hold similar attitudes towards their sonically similar everyday counterpart: actual human screaming. Call this the screamed vocals problem. To solve the problem, I argue we must attend to the anti-sublimating aims that get expressed in the emotional hardcore vocalist’s choice to scream the lyrics. Screamed vocals (...) help us see the value in rejecting (a) restrictive social norms of emotional expressiveness and (b) restrictive artistic norms about how one ought to express or represent pain in art, namely that if one is going to do so they must ensure the pain has been ‘beautified’. In developing this second point I argue that emotional hardcore is well-suited (though not individually so) for putting pressure on longstanding views in the history of aesthetics about the formal relationship between art and human pain.

ABSTRACT:Organizations constitute morally-complex environments, requiring organization members to possess levels of moral courage sufficient to promote their ethical action, while refraining from unethical actions when faced with temptations or pressures. Using a sample drawn from a military context, we explored the antecedents and consequences of moral courage. Results from this four-month field study demonstrated that authentic leadership was positively related to followers’ displays of moral courage. Further, followers’ moral courage fully mediated the effects of authentic leadership on followers’ ethical and (...) pro-social behaviors. Theoretical and practical implications for further integrating the work on moral courage, authentic leadership and ethics are discussed. (shrink)

Some modern cosmological models predict the appearance of Boltzmann Brains: observers who randomly fluctuate out of a thermal bath rather than naturally evolving from a low-entropy Big Bang. A theory in which most observers are of the Boltzmann Brain type is generally thought to be unacceptable, although opinions differ. I argue that such theories are indeed unacceptable: the real problem is with fluctuations into observers who are locally identical to ordinary observers, and their existence cannot be swept under the rug (...) by a choice of probability distributions over observers. The issue is not that the existence of such observers is ruled out by data, but that the theories that predict them are cognitively unstable: they cannot simultaneously be true and justifiably believed.

We have a much better understanding of physics than we do of consciousness. I consider ways in which intrinsically mental aspects of fundamental ontology might induce modifications of the known laws of physics, or whether they could be relevant to accounting for consciousness if no such modifications exist. I suggest that our current knowledge of physics should make us skeptical of hypothetical modifications of the known rules, and that without such modifications it’s hard to imagine how intrinsically mental aspects could (...) play a useful explanatory role.

This book provides an account of the nature of time, especially time's arrow and the role of entropy, at a semi-popular level. Special attention is given to statistical mechanics, the past hypothesis, and possible cosmological explanations thereof.

I discuss "Poetic Naturalism" -- there is only one world, the natural world, but there are many ways of talking about it -- both as a general concept, and how it accounts for our actual world. I talk about emergence, fundamental physics, entropy and complexity, the origins of life and consciousness, and moral constructivism.

I defend the extremist position that the fundamental ontology of the world consists of a vector in Hilbert space evolving according to the Schrödinger equation. The laws of physics are determined solely by the energy eigenspectrum of the Hamiltonian. The structure of our observed world, including space and fields living within it, should arise as a higher-level emergent description. I sketch how this might come about, although much work remains to be done.

Disconnecting a patient from artificial life support, on their request, is often if not always a matter of letting them die, not killing them—and sometimes, permissibly doing so. Stopping a patient’s heart on request, by contrast, is a kind of killing, and rarely if ever a permissible one. The difference seems to be that procedures of the first kind remove an unwanted external support for bodily functioning, rather than intervening in the body itself. What should we say, however, about cases (...) at the boundary—procedures involving items that seem bodily in some respects, but not others? When, for instance, does deactivating an implanted device like a pacemaker count as killing, and when as letting die? Contra existing proposals, I argue that the boundaries of the body for this purpose are not drawn at the boundaries of the self, or (if this is different) the human organism. Nor should we determine when we are killing and when we are letting die by deferring to existing practices for distinguishing ongoing from completed treatment. Rather, I argue that whether something (organic or inorganic) counts as body part for purposes of this distinction depends on the results of a normative analysis of the particular character of our rights in it—particularly, whether and in what way these rights ought to be alienable. I conclude by arguing that there are likely good reasons to recognize distinctively “bodily” rights and restrictions in at least some implantable devices. (shrink)

Cosmological models that invoke a multiverse - a collection of unobservable regions of space where conditions are very different from the region around us - are controversial, on the grounds that unobservable phenomena shouldn't play a crucial role in legitimate scientific theories. I argue that the way we evaluate multiverse models is precisely the same as the way we evaluate any other models, on the basis of abduction, Bayesian inference, and empirical success. There is no scientifically respectable way to do (...) cosmology without taking into account different possibilities for what the universe might be like outside our horizon. Multiverse theories are utterly conventionally scientific, even if evaluating them can be difficult in practice. (shrink)

This article asks whether personal ventilators should be redistributed to maximize lives saved in emergency condition, like the COVID-19 pandemic. It begins by examining extant claims that items like ventilators are literally parts of their user’s bodies. Arguments in favor of incorporation for ventilators fail to show that they meet valid sufficient conditions to be body parts, but arguments against incorporation also fail to show that they fail to meet clearly valid necessary conditions. Further progress on this issue awaits clarification (...) of difficult normative, conceptual, and metaphysical questions about the possible boundaries of a person’s body. Rather than relying solely on incorporation arguments, we propose an argument against reallocation from widely accepted anti-discrimination principles. Possession of a personal ventilator is an obvious marker of disability identity; thus, reallocating ventilators from those that already possess them discriminates on the basis of a stigmatized trait – a paradigm case of presumptively wrongful discrimination. This discrimination claim, taken together with uncertainty about the bodily status of ventilators, yields a strong presumption against personal ventilator reallocation. (shrink)

Technological measures meant to change sexual orientation are, we have argued elsewhere, deeply alarming, even and indeed especially if they are safe and effective. Here we point out that this in part because they produce a distinctive kind of ‘clinical collective action problem’, a sort of dilemma for individual clinicians and researchers: a treatment which evidently relieves the suffering of particular patients, but in the process contributes to a practice that substantially worsens the conditions that produce this suffering in the (...) first place. We argue that the role obligations of clinicians to relieve the suffering of their patients put them in a poor position to solve this problem, though they can take measures to avoid complicity in the harms that would result from widespread use of individually safe and effective reorientation biotechnology. But in the end the medical community as a whole still seems obligated to provide these measures, if they become technologically feasible. Medical researchers are in a better position to prevent the harms that would result if reorientation techniques were safe, effective and widely available. We argue that the harms attendant on the development of safe and effective re-orientation techniques give researchers reason to avoid ‘applied‘ research aimed at developing these techniques, and to be careful in the conduct of basic orientation research which might be applied in this way.

This paper argues for Serious Distributive Egalitarianism – the view that some material inequalities are seriously objectionable as such; not merely, say, because such inequalities tend to generate inequalities in status. Social justice requires equality, I argue, because basic social institutions produce important goods and are produced in turn by the relevantly equal contributions of all those that comply with them. E.g., basic social institutions make it much easier to produce cooperatively than it would be in their absence; therefore, these (...) institutions produce, among other things, opportunities to participate in particular productive enterprises. But basic social institutions are themselves produced, in large part, by the compliance of those subject to them; these subjects, therefore, contribute to the production of the goods that basic institutions produce. This gives (at least) every compliant subject of basic social institutions a claim on these goods. And, I argue that, though some do contribute more to the maintenance of basic institutions than others, those who contribute more are too responsible for the fact that others contribute less to point to the consequences of this difference as a reason they should get greater returns. I conclude that all subjects of basic social institutions have equally forceful and forcefully equal claims on the goods these institutions produce; claims that render inequalities in the Distribution of these goods Seriously objectionable as such.

In tackling emergentist Marxism in depth, this well-written volume demonstrates that critical realism and materialist dialectics are indispensable to theorizing the functioning of complex social and physical systems. Author Sean Creaven investigates Marxâes dialectics of being and consciousness, forces and relations of production, base and superstructure, class structure and class conflict, and demonstrates how they allow the social analyst to conceptualize geo-history as embodying a tendential evolutionary directionality, rather than as simply random or indeterminate in terms of its outcomes. (...) For those interested in social and political theory, Marxism and communism and contemporary social theory, this outstanding volume is an in important read and a valuable resource. (shrink)

This paper argues that disabled people can be healthy. I argue, first, following the well-known ‘social model of disability’, that we should prefer a usage of ‘disabled’ which does not imply any kind of impairment that is essentially inconsistent with health. This is because one can be disabled only because limited by false social perception of impairment and one can be, if impaired, disabled not because of the impairment but rather only because of the social response to it. Second, I (...) argue that it is often wrong to use the term ‘healthy’ in a way that makes health inconsistent with any degree whatsoever of health-relevant bodily dysfunction. Whether someone is ‘healthy’ properly-so-called depends on standards of health presupposed in conversational context. Sometimes, I argue, these standards are or ought to be lax enough to allow some people with some health deficits still to count as ‘healthy’ per se. Taking inspiration from David Lewis and Mary Kate Mcgowan, I go on to argue that denying that someone is ‘healthy’ in a context typically succeeds in shifting going presuppositions to require standards strict enough to make that denial acceptable. And this, I conclude by arguing, often constitutes an abuse of conversational power. (shrink)

It seems natural to ask why the universe exists at all. Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. But there might not be an absolute answer to why it exists. I argue that any attempt to account for the existence of something rather than nothing must ultimately bottom out in a set of brute facts; the universe simply is, without ultimate cause or explanation.

Celebrated yoga teacher and activist Seane Corn shares pivotal accounts of her life with raw honesty—enriched with in-depth spiritual teachings—to help us heal, evolve, and change the world “My first lessons in spirituality and yoga had nothing to do with a mat, but everything to do with waking up. They included angels, seeing God, and being in Heaven. But, believe me, not the way you might think.” So begins Revolution of the Soul. What comes next reads like a riveting memoir (...) filled with uncensored moments of joy, pain, wonder, and humor. Except, this book is so much more than that. Seane's real purpose is to guide us into a deep, gut-level understanding of our highest Self through yoga philosophy and other tools for emotional healing—not just as abstract ideas but as embodied, fully felt wisdom. Why? To spark a "revolution of the soul" in each of us, so we can awaken to our purpose and become true agents of change. Just a few of the stops along the way include: The everyday "angels" Seane finds in the gritty corners of New York's 1980s East Village; her early struggles as a total yoga-class misfit; the profound shadow work and body-based practices that helped her to heal childhood trauma, OCD, unhealthy behaviors, and relationship wounding; hard-earned lessons from some of the most heartbreaking places on the planet; and many other unforgettable teaching stories.

We study the question of how to decompose Hilbert space into a preferred tensor-product factorization without any pre-existing structure other than a Hamiltonian operator, in particular the case of a bipartite decomposition into "system" and "environment." Such a decomposition can be defined by looking for subsystems that exhibit quasi-classical behavior. The correct decomposition is one in which pointer states of the system are relatively robust against environmental monitoring (their entanglement with the environment does not continually and dramatically increase) and remain (...) localized around approximately-classical trajectories. We present an in-principle algorithm for finding such a decomposition by minimizing a combination of entanglement growth and internal spreading of the system. Both of these properties are related to locality in different ways. This formalism could be relevant to the emergence of spacetime from quantum entanglement. (shrink)

The need to understand the systems that support ethical health research has long been recognized, but there are limited descriptions of actual health research ethics (HRE) systems. Using participatory network mapping methods, we empirically defined Malaysia's HRE system. 13 Malaysian stakeholders identified 4 overarching and 25 specific HRE system functions and 35 actors internal and 3 external to the Malaysian HRE system responsible for those functions. Functions requiring the most attention were: advising on legislation related to HRE; optimizing research value (...) to society; and defining standards for HRE oversight. Internal actors with the greatest potential for more influence were: the national network of research ethics committees; non-institution-based research ethics committees; and research participants. The World Health Organization, an external actor, had the largest untapped potential for influence overall. In summary, this stakeholder-driven process identified HRE system functions and actors that could be targeted to increase HRE system capacity. (shrink)

We study the conservation of energy, or lack thereof, when measurements are performed in quantum mechanics. The expectation value of the Hamiltonian of a system changes when wave functions collapse in accordance with the standard textbook treatment of quantum measurement, but one might imagine that the change in energy is compensated by the measuring apparatus or environment. We show that this is not true; the change in the energy of a state after measurement can be arbitrarily large, independent of the (...) physical measurement process. In Everettian quantum theory, while the expectation value of the Hamiltonian is conserved for the wave function of the universe, it is not constant within individual worlds. It should therefore be possible to experimentally measure violations of conservation of energy, and we suggest an experimental protocol for doing so. (shrink)

The Pneumatist school of medicine has the distinction of being the only medical school in antiquity named for a belief in a part of a human being. Unlike the Herophileans or the Asclepiadeans, their name does not pick out the founder of the school. Unlike the Dogmatists, Empiricists, or Methodists, their name does not pick out a specific approach to medicine. Instead, the name picks out a belief: the fact that pneuma is of paramount importance, both for explaining health and (...) disease, and for determining treatments for the healthy and sick. In this paper, we re-examine what our sources say about the pneuma of the Pneumatists in order to understand what these physicians thought it was and how it shaped their views on physiology, diagnosis and treatment.

We provide a derivation of the Born Rule in the context of the Everett (Many-Worlds) approach to quantum mechanics. Our argument is based on the idea of self-locating uncertainty: in the period between the wave function branching via decoherence and an observer registering the outcome of the measurement, that observer can know the state of the universe precisely without knowing which branch they are on. We show that there is a uniquely rational way to apportion credence in such cases, which (...) leads directly to the Born Rule. Our analysis generalizes straightforwardly to cases of combined classical and quantum self-locating uncertainty, as in the cosmological multiverse. (shrink)

It is commonplace in discussions of modern cosmology to assert that the early universe began in a special state. Conventionally, cosmologists characterize this fine-tuning in terms of the horizon and flatness problems. I argue that the fine-tuning is real, but these problems aren't the best way to think about it: causal disconnection of separated regions isn't the real problem, and flatness isn't a problem at all. Fine-tuning is better understood in terms of a measure on the space of trajectories: given (...) reasonable conditions in the late universe, the fraction of cosmological histories that were smooth at early times is incredibly tiny. This discussion helps clarify what is required by a complete theory of cosmological initial conditions. (shrink)

Athenaeus of Attalia distinguishes two types of exercise or training (γυμνασία) that are required at each stage of life: training of the body and training of the soul. He says that training of the body includes activities like physical exercises, eating, drinking, bathing and sleep. Training of the soul, on the other hand, consists of thinking, education, and emotional regulation (in other words, 'philosophy'). The notion of 'training of the soul' and the contrast between 'bodily' and 'psychic' exercise is common (...) in the Academic and Stoic traditions Athenaeus is drawing from; however, he is the earliest extant medical author to distinguish these kinds of training and to treat them as equally important aspects of regimen. In this paper, I propose some reasons why he found this distinction useful, and I examine how he justified incorporating it into his writings on regimen, namely by attributing Plato's beliefs about regimen to Hippocrates, a strategy Galen would adopt well over a century later.

Effective Field Theory (EFT) is the successful paradigm underlying modern theoretical physics, including the "Core Theory" of the Standard Model of particle physics plus Einstein's general relativity. I will argue that EFT grants us a unique insight: each EFT model comes with a built-in specification of its domain of applicability. Hence, once a model is tested within some domain (of energies and interaction strengths), we can be confident that it will continue to be accurate within that domain. Currently, the Core (...) Theory has been tested in regimes that include all of the energy scales relevant to the physics of everyday life (biology, chemistry, technology, etc.). Therefore, we have reason to be confident that the laws of physics underlying the phenomena of everyday life are completely known. (shrink)

A provocative close reading revealing a radical, proto-phenomenological Socrates.

A person’s body can, it seems, survive well after losing the capacity to support Lockean personhood. If our rights in our bodies are, basically, rights in our selves or persons, this seems to imply that we do not after all have a right to direct the disposition of our living remains via advance directive. Govind Persad argues that our rights over our bodies persist after the loss of our personhood; we have a right to insist that our bodies die after (...) we are gone for much the same reason that we have a right to decide whether or not to donate organs, after our death. Persad’s conclusion may be right; however, his arguments regarding body rights are insufficient. Persad’s suggestion that our rights in our bodies come from a history of acting and sensing through them cannot, quite, be right, since we act and sense through tools, as well. Nor should we accept Persad’s arguments, from intuitions in cases involving posthumous pregnancy, that our posthumous body rights are powerful enough to allow choices that will result in the death of beings that need our living remains to survive. Problems with these intuitions point to a more general concern for this sort of case-based intuitionistic method: it presupposes that what body rights we have is a matter of ‘natural right’, accessible to all, rather than a function of how social institutions do or should resolve conflicts about the proper way of defining our authority over our bodies.

Achieving the global benefits of artificial intelligence (AI) will require international cooperation on many areas of governance and ethical standards, while allowing for diverse cultural perspectives and priorities. There are many barriers to achieving this at present, including mistrust between cultures, and more practical challenges of coordinating across different locations. This paper focuses particularly on barriers to cooperation between Europe and North America on the one hand and East Asia on the other, as regions which currently have an outsized impact (...) on the development of AI ethics and governance. We suggest that there is reason to be optimistic about achieving greater cross-cultural cooperation on AI ethics and governance. We argue that misunderstandings between cultures and regions play a more important role in undermining cross-cultural trust, relative to fundamental disagreements, than is often supposed. Even where fundamental differences exist, these may not necessarily prevent productive cross-cultural cooperation, for two reasons: (1) cooperation does not require achieving agreement on principles and standards for all areas of AI; and (2) it is sometimes possible to reach agreement on practical issues despite disagreement on more abstract values or principles. We believe that academia has a key role to play in promoting cross-cultural cooperation on AI ethics and governance, by building greater mutual understanding, and clarifying where different forms of agreement will be both necessary and possible. We make a number of recommendations for practical steps and initiatives, including translation and multilingual publication of key documents, researcher exchange programmes, and development of research agendas on cross-cultural topics.
