Ayahuasca, an ancient Amazonian psychedelic tea traditionally used ceremonially among indigenous peoples, has recently become known as a possible treatment for a wide range of disorders. The awareness of this sacred medicine has grown exponentially over the past decade, attracting westerners from a wide variety of backgrounds, hoping to find treatment for a myriad of emotional and physical illnesses, as well as spiritual needs. In the wake of the commercialization and westernization of the use of ayahuasca, and the subsequent proliferation (...) of ayahuasca treatment centers, this paper examines the benefits and possible risks of this form of therapy in an effort to create a safety protocol for Westerners in this context. The most practical approach to increasing safety for Westerners attending these Amazonian treatment centers is to educate the seeker prior to treatment and to provide access to specialized therapeutic aftercare services.

Ebejer and Morden (Paternalism in the Marketplace: Should a Salesman Be His Buyer's Keeper?, Journal of Business Ethics 7, 1988) propose limited paternalism as a sufficient regulative condition for a professional ethic of sales. Although the principle is immediately appealing, its application can lead to a counter-productive ethical quandary I call the Pontius Pilate Plight. This quandary is the assumption that ethical agents' hands are clean in certain situations even if they have done something they condemn as immoral. Since limited (...) paternalism can give rise to this queer conclusion in the salesperson/buyer relationship, the principle is suspect. It may be a necessary condition for ethical sales, but is not sufficient. This discussion concludes by suggesting two additional criteria which, when complemented by the limited paternalism principle, are jointly sufficient. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Christian PhilosopherKerry S. WaltersThe Christian Philosopher, by Cotton Mather; edited by Winton U. Solberg; cxlii & 488 pp. Urbana: University of Illinois Press, 1994, $49.95.Poor Cotton Mather! For well over two centuries now he has been a popular icon of unctuous self-righteousness, superstitious fanaticism, and dogmatic intolerance. Nor has endorsement of this stereotype been confined to casual laypersons who know of Mather only from lurid accounts of (...) Salem witch-hunting. Scholars who ought to know better often buy into it. Perry Miller, the doyen of early American studies, consistently wrote of Mather in a particularly unsympathetic manner. More odious, as Professor Solberg reminds us (p. xciii), was the treatment by historians at a Florida planetarium who in 1982 put together a short film on early European and American doomsday predictors which included segments on Mather the astronomer. When these segments appeared, a projector was programmed to flash the words “Feel Free to Boo and Hiss” on the planetarium’s dome—an invitation which audiences, presumably, gleefully accepted.Mather deserves better than this, and Winton Solberg’s critical edition of The Christian Philosopher goes a long way towards rehabilitating the Puritan divine. Along with recent studies such as Kenneth Murdock’s edition of Mather’s Magnalia Christi Americana (1977) and Kenneth Silverman’s masterful The Life and Times of Cotton Mather (1984), Solberg’s study painstakingly presents us with a detailed account of a man who undoubtedly was one of the most important literary figures in early America.Mather published The Christian Philosopher in 1721, seven years before his [End Page 167] death and eight years after being named to the Royal Society of London. The book was both the culmination of a lifetime of learning as well as a calculated effort on Mather’s part to show that his election to the prestigious Royal Society was deserved. The book is the first attempt by an American-born author to take a comprehensive look at the “new learning” associated with that period known since as the Enlightenment. Mather was an omnivorous reader and an equally thorough observer of natural phenomena, and he welcomed the scientific interpretations of reality offered by such savants as Isaac Newton, Robert Boyle, and John Ray. In the mind of Mather, such explanations posed no challenge to the Christian worldview. On the contrary, he concluded, they supported it by providing clear and indisputable evidence of design in nature. The Christian Philosopher (or, in more contemporary jargon, The Christian Scientist) is Mather’s attempt to defend this thesis. It is an exhaustive (and sometimes exhausting!) compendium of data gleaned from the natural realm which, in Mather’s judgment, irrefutably points to the existence of a grand Designer. Although Mather explicitly claimed that his primary goal in writing the book was to demonstrate that atheism is contrary to reason, he also penned one of the New World’s first systematic Enlightenment documents.One of the difficulties in reading The Christian Philosopher traditionally has been the sheer breadth of learning that went into its composition. Mather cites over four hundred books, includes hundreds of allusions to classical and scriptural sources, and so inundates the reader with evidence in support of his fundamental design argument that it is quite easy to lose one’s way. Professor Solberg has considerably lightened these burdens with his critical edition. He prefaces Mather’s text with a masterful 115-page introduction which places the work in its historical context as well as analyzes its methodology and arguments. Moreover, his edition includes 170 pages of endnotes, biographical notes, biblical references and a recapitulation of Mather’s own sources. Finally, Solberg supplies almost each page of Mather’s text with footnotes that identify literary or scriptural allusions and translate Mather’s liberal use of Greek and Latin quotations.Solberg’s edition of The Christian Philosopher will prove, I’m confident, to be the definitive text. It is an invaluable reference tool for the specialist, but it can also serve as a friendly and intriguing introduction for the layperson. Convinced Puritan-bashers who read this study may still regard Mather’s worldview with distaste, but I suspect that Solberg’s sensitive... (shrink)

ABSTRACT A trivalent theory of indicative conditionals automatically enforces Stalnaker's thesis – the equation between probabilities of conditionals and conditional probabilities. This result holds because the trivalent semantics requires, for principled reasons, a modification of the ratio definition of conditional probability in order to accommodate the possibility of undefinedness. I explain how this modification is motivated and how it allows the trivalent semantics to avoid a number of well-known triviality results, in the process clarifying why these results hold for many (...) bivalent theories. In short, the slew of triviality results published in the last 40-odd years need not be viewed as an argument against Stalnaker's thesis: it can be construed instead as an argument for abandoning the bivalent requirement that indicative conditionals somehow be assigned a truth-value in worlds in which their antecedents are false.

We derive a probabilistic account of the vagueness and context-sensitivity of scalar adjectives from a Bayesian approach to communication and interpretation. We describe an iterated-reasoning architecture for pragmatic interpretation and illustrate it with a simple scalar implicature example. We then show how to enrich the apparatus to handle pragmatic reasoning about the values of free variables, explore its predictions about the interpretation of scalar adjectives, and show how this model implements Edgington’s Vagueness: a reader, 1997) account of the sorites paradox, (...) with variations. The Bayesian approach has a number of explanatory virtues: in particular, it does not require any special-purpose machinery for handling vagueness, and it is integrated with a promising new approach to pragmatics and other areas of cognitive science.

Implicit bias results from living in a society structured by race. Tamar Gendler has drawn attention to several epistemic costs of implicit bias and concludes that paying some costs is unavoidable. In this paper, we reconstruct Gendler’s argument and argue that the epistemic costs she highlights can be avoided. Though epistemic agents encode discriminatory information from the environment, not all encoded information is activated. Agents can construct local epistemic environments that do not activate biasing representations, effectively avoiding the consequences of (...) activation. We conclude that changing our local environments provides a way to avoid paying implicit bias’s epistemic costs. (shrink)

The pull to coordinate with other individuals is fundamental, serving as the basis for our social connectedness to others. Discussed is a dynamical and ecological perspective to joint action, an approach that embeds the individual’s mind in a body and the body in a niche, a physical and social environment. Research on uninstructed coordination of simple incidental rhythmic movement, along with research on goal‐directed, embodied cooperation, is reviewed. Finally, recent research is discussed that extends the coordination and cooperation studies, examining (...) how synchronizing with another, and how emergent social units of perceiving and acting are reflected in people’s feelings of connection to others.

The rapid and unplanned change to teaching and learning in the online format brought by COVID-19 has likely impacted many, if not all, aspects of university students' lives worldwide. To contribute to the investigation of this change, this study focuses on the impact of the pandemic on student well-being, which has been found to be as important to student lifelong success as their academic achievement. Student well-being has been linked to their engagement and performance in curricular, co-curricular, and extracurricular activities, (...) intrinsic motivation, satisfaction, meaning making, and mental health. The purpose of this study was to examine how student perceptions of their degree completion and future job prospects during the pandemic impact their well-being and what role university support plays in this relationship. We used the conservation of resources theory to frame our study and to develop five hypotheses that were later tested via structural equation modeling. Data were collected from 2,707 university students in France, Germany, Russia, and UK via an online survey. The results showed that university support provided by instructors and administration plays a mediating role in the relationship between the perceived impact of COVID-19 on degree completion and future job prospects and levels of student well-being. Student well-being is decreased by their concerns for their degree completion but not by their concerns for future job prospects. In turn, concerns for future job prospects affect student well-being over time. These results suggest that in a “new normal,” universities could increase student well-being by making support to student studies a priority, especially for undergraduates. Also, universities should be aware of the students' changing emotional responses to crisis and ensure visibility and accessibility of student support. (shrink)

In this paper, I develop a view about machine autonomy grounded in the theoretical frameworks of 4E cognition and PF Strawson’s reactive attitudes. I begin with critical discussion of White, and conclude that his view is strongly committed to functionalism as it has developed in mainstream analytic philosophy since the 1950s. After suggesting that there is good reason to resist this view by appeal to developments in 4E cognition, I propose an alternative view of machine autonomy. Namely, machines count as (...) autonomous when we members of the moral community adopt reactive attitudes in response to their actions. I distinguish this view from White’s and suggest assets and liabilities of this approach. (shrink)

In this article, I address concerns that the ontological priority claims definitive of ontic structural realism are as they stand unclear, and I do so by placing these claims on a more rigorous formal footing than they typically have been hitherto. I first of all argue that Kit Fine’s analysis of ontological dependence furnishes us with an ontological priority relation that is particularly apt for structuralism. With that in place, and with reference to two case studies prominent within the structuralist (...) literature, I consider whether any of structuralism’s distinctive priority claims may be regarded as warranted. The discussion as a whole has largely negative implications for the radical structuralism of French and Ladyman (including their ‘eliminativist’ interpretation of it), largely positive implications for the moderate structuralism primarily advocated by Esfeld and Lam, and some broad lessons for contemporary fundamentalist metaphysics as a whole. 1 Introduction2 The Right Priority Relation for Structuralism: Supervenience or Dependence?3 Introducing Ontological Dependence4 Fine’s System5 The Priority of Structure 1: Entangled Quantum Particles6 The Priority of Structure 2: The Group-Theoretic Conception of Elementary Particles7 Concluding Remarks.

Arendt's conception of culture could supersede claims that nature's intrinsic value or human interests best ground environmental ethics. Fusing ancient Greek notions of non-instrumental value and Roman concerns for cultivating and preserving worldly surroundings, culture supplies an ethic for the treatment of nonhuman things. Unlike a system of philosophical propositions, an Arendtian ecology could only arise in public deliberation, since culture's qualitative judgements are intrinsically linked to processes of political persuasion.

Ontic structural realism is at its core the view that “structure is ontologically fundamental.” Informed from its inception by the scientific revolutions that punctuated the 20th century, its advocates often present the position as the perspective on ontology best befitting of modern physics. But the idea that structure is fundamental has proved difficult to articulate adequately, and what OSR's claimed naturalistic credentials consist in is hard to precisify as well. Nor is it clear that the position is actually supported by (...) our most fundamental physical theories. What is clear, however, is that structuralists have revealed a seam of material at the core of modern physics that is replete with implications for metaphysics. This article will survey some positions subsumed under the rubric of OSR, considering both their warrant and the interconnections that exist between them. It will be argued that the fundamental kind properties pose a challenge to ontic structuralism, because it seems that these properties do not supervene upon the relevant structures. But it will also be argued that the development of structuralist metaphysics will require both an engagement with the details of modern physical theories and the deployment of tools more typically developed in a priori metaphysics. As such, it seems armchair metaphysicians have not just a stake in whether OSR's claims may ultimately be shown to stand up, but a crucial role to play in getting them to the point where they can be subjected to scrutiny in the first place.

Abstract: Chomsky (1986) has claimed that the prima facie incompatibility between descriptive linguistics and semantic externalism proves that an externalist semantics is impossible. Although it is true that a strong form of externalism does not cohere with descriptive linguistics, sociolinguistic theory can unify the two approaches. The resulting two-level theory reconciles descriptivism, mentalism, and externalism by construing community languages as a function of social identification. This approach allows a fresh look at names and definite descriptions while also responding to Chomsky's (...) (1993, 1995) challenge to articulate an externalist theory of meaning that can be used in the scientific investigation of language. (shrink)

This model explores consensus among agents in a population in terms of two properties. The first is a probability of belief change. This value indicates how likely agents are to change their mind in interactions. The other is the size of the agents audience: the proportion of the population the agent has access to at any given time. In all instances, the agents converge on a single belief, although the agents are arational. I argue that this generates a skeptical hypothesis: (...) any instance of purportedly rational consensus might just as well be a case of arational belief convergence. I also consider what the model tells us about increasing the likelihood that one agent’s belief is adopted by the rest. Agents are most likely to have their beliefs adopted by the entire population when their value for PBC is low relative to the rest of the population and their audience sizes are roughly three-quarters of the largest possible audience. I further explore the consequences of dogmatists to the population; individuals who refuse to change their mind end up polarizing the population. I conclude with reflections on the supposedly special character of rationality in belief-spread. (shrink)

Ontic structural realism is a thesis of fundamentality metaphysics: the thesis that structure, not objects, has fundamental status. Claimed as the metaphysic most befitting of modern physics, OSR first emerged as an entreaty to eliminate objects from the metaphysics of fundamental physics. Such elimination was urged by Steven French and James Ladyman on the grounds that only it could resolve the ‘underdetermination of metaphysics by physics’ that they claimed reduced any putative objectual commitment to a merely ‘ersatz’ form of realism. (...) Few, however, have joined French and Ladyman either in acknowledging that such underdetermination exists or in attributing to it such drastic consequences. However, an alternative view that physics does sanction objects, albeit merely as ontologically secondary entities, represents a different and seemingly less extreme route to the same conclusion regarding the fundamentality of structure. But since what it means to be ‘ontologically prior’ is itself a vexed philosophical question, a stance must be taken as to how we are to understand priority before its prospects may be evaluated. In an earlier paper, I outlined how Fine’s notion of ontological dependence might be utilized to defend the priority-based approach to structuralism. Since then, however, I have become convinced that that ontological dependence is not a relation of priority after all. As a result, the arguments outlined in that paper stand in need of reassessment. In this work, I consider the prospects for priority-based structuralism when expressed in the idiom of determination. My conclusion will be that it has yet to be vindicated by our best physical theories, owing to the failure of symmetry structures to determine the world’s inventory of fundamental kinds. Nevertheless, the same symmetry considerations point towards there being renewed prospects for eliminativism—an eliminativism, moreover, of more naturalistic appeal than that hitherto associated with OSR. 1Introduction 2Structuralist Strategies 3Defining Ontological Priority: Dependence or Determination? 4Structuralism in the Idiom of Determination 4.1Determining plurality 4.2Determining kind properties 5A Reinvigorated Eliminativism.

A naturalistic approach to expert-identification begins by asking, ‘how do novices pick out putative experts?’ Alvin Goldman and Elizabeth Anderson, representing a fairly common approach, consider agents’ psychological biases as well as social situatedness. As good as this is, culture’s role in shaping cognitive mechanisms is neglected. An explanatory framework that works well to accommodate culturally-sensitive mechanisms is Peircean semiotics. His triadic approach holds that signs signify objects to interpreters. Applying the triadic model to expert-identification: novices interpret signs of expertise (...) as pointing to particular experts. The main advantage of the framework is that it is significantly more nuanced than the Goldman-Anderson model in describing how agents identify experts. It explicitly accommodates cultural and agential differences in expert-identification. It also explicitly admits the possibility of rational disagreement in assessment of evidence for expertise. But these advantages come at a cost. Namely, it’s difficult in theory – as well as practice – to make one’s way into the semiotic system of someone from another culture to help guide them away from fraudulent experts. Even so, it’s a trade-off worth making since it organizes relevant details for expert-identification, which is a first step in sketching a better normative theory. (shrink)

Brussen, Kerri Anne The National Health and Medical Research Council released a new set of dietary guidelines on 18 February 2013, to help ensure that Australians continue to make healthy food choices based on the best available scientific evidence. Unlike the 2003 guidelines which were based on nutrients, these guidelines are based on food and food groups. The guidelines encourage the consumption of a varied diet and physical exercise. They also encourage the limiting of energy-dense nutrient-poor food. By making these (...) food choices, we can help to reduce our risk of diet-related disease. (shrink)

Embodied, embedded, enactive, and extended theorists do not typically focus on the ontological frameworks in which they develop their theories. One exception is 4E theories that embrace New Mechanism. In this paper, we endorse the New Mechanist’s general turn to ontology, but argue that their ontology is not the best on the market for 4E theories. Instead, we advocate for a different ontology: causal powers realism. Causal powers realism posits that psychological manifestations are the product of mental powers, and that (...) mental powers are empirically-discoverable features of individuals that account for the causal work those individuals do. We contend that causal powers realism provides a unifying framework for the central commitments of 4E theories, as well as additional resources for theorizing in a 4E framework. And while New Mechanism offers some of these resources as well, we argue that causal powers realism is ultimately the better of the two. (shrink)

The view that the fundamental kind properties are intrinsic properties enjoys reflexive endorsement by most metaphysicians of science. But ontic structural realists deny that there are any fundamental intrinsic properties at all. Given that structuralists distrust intuition as a guide to truth, and given that we currently lack a fundamental physical theory that we could consult instead to order settle the issue, it might seem as if there is simply nowhere for this debate to go at present. However, I will (...) argue that there exists an as-yet untapped resource for arguing for ontic structuralism – namely, the way that fundamentality is conceptualized in our most fundamental physical frameworks. By arguing that physical objects must be subject to the ‘Goldilock's principle’ if they are to count as fundamental at all, I argue that we can no longer view the majority of properties defining them as intrinsic. As such, ontic structural realism can be regarded as the most promising metaphysics for fundamental physics, and that this is so even though we do not yet claim to know precisely what that fundamental physics is.

Brussen, Kerri Anne In 2002, euthanasia became legal in the Netherlands. Since then, the Groningen Protocol has been endorsed, allowing infanticide for disabled babies. More recently, a citizen's initiative is being prepared to propose to the Dutch government that people should be allowed to legally terminate their life if they consider it completed. The slippery slope in the Netherlands appears to be well lubricated.
