Can the use of psychedelic drugs induce lasting changes in metaphysical beliefs? While it is popularly believed that they can, this question has never been formally tested. Here we exploited a large sample derived from prospective online surveying to determine whether and how beliefs concerning the nature of reality, consciousness, and free‑will, change after psychedelic use. Results revealed significant shifts away from ‘physicalist’ or ‘materialist’ views, and towards panpsychism and fatalism, post use. With the exception of fatalism, these changes endured (...) for at least 6 months, and were positively correlated with the extent of past psychedelic‑use and improved mental‑health outcomes. Path modelling suggested that the belief‑shifts were moderated by impressionability at baseline and mediated by perceived emotional synchrony with others during the psychedelic experience. The observed belief‑shifts post‑psychedelic‑use were consolidated by data from an independent controlled clinical trial. Together, these findings imply that psychedelic‑use may causally influence metaphysical beliefs—shifting them away from ‘hard materialism’. We discuss whether these apparent effects are contextually independent. (shrink)

Cryonics is the preservation of legally dead human bodies at the temperature of liquid nitrogen in the hope that future technologies will be able to revive them. In philosophical debates surrounding this practice, arguments often focus on prudential implications of cryopreservation, or moral arguments on a societal level. In this paper, we claim that this debate is incomplete, since it does not take into account a significant relational concern about cryonics. Specifically, we argue that attention should be paid to the (...) potential implications of cryopreservation for the mourning processes of surviving loved ones. Cryopreservation increases the likelihood of disruption of the practical and mental tasks involved in a successful mourning process, which can negatively impact survivors of the cryopreserved patient. To illustrate my argument, we will draw on a case study from the 2019 documentaryHope Frozen. We aim to introduce this concern, in order to gain a more complete view on the potential implications of cryopreservation. (shrink)

Les diverses formes de vie en commun appellent des modalités de reconnaissance très différentes. Mais il s'agit toujours de combats pour une insertion sociale réussie. Voici une tentative de déclinaison de la nature sociale de l'homme de façon à saisir les grammaires de l'humain comme les grammaires de la reconnaissance.

The prospect of using genome technologies to modify the human germline has raised profound moral disagreement but also emphasizes the need for wide-ranging discussion and a well-informed policy response. The Hinxton Group brought together scientists, ethicists, policymakers, and journal editors for an international, interdisciplinary meeting on this subject. This consensus statement formulated by the group calls for support of genome editing research and the development of a scientific roadmap for safety and efficacy; recognizes the ethical challenges involved in clinical reproductive (...) applications of genome editing but, importantly, rejects the idea that human reproductive germline modification is necessarily morally unacceptable; and highlights the importance of meaningful engagement in discussions of genome editing and the development of regulation and oversight mechanisms to govern future uses of such technologies.

This book collects essays from the 2006 and 2007 International Philosophy Colloquia Evian, centred around a central problem in the philosophy of mind: the relationship between the human faculty of sensory experience and the faculty of conceptual reflection, that is self-consciousness. Containing articles by philosophers of eight nationalities, in three languages (English, French, German), and of "analytical" as well as "continental" provenance, it beautifully represents the spirit of the colloquia. Authors include Joshua Andresen (AU Beirut), Valérie Aucouturier (Kent U / (...) U Paris I), Karin de Boer (KU Leuven), Santiago Echeverri (U Genève), Roberto Farneti (LU Bolzano), Tim Henning (JLU Giessen), Felix Koch (Columbia U), Christophe Laudou (Madrid), David Lauer (FU Berlin), Jason Leddington (Bucknell U), Nicolas Monseu (UC Louvain), Soraya Nour (HU Berlin), Hans Bernhard Schmid (U Wien), Henning Tegtmeyer (U Leipzig).

Both language and genes evolve by transmission over generations with opportunity for differential replication of forms. The understanding that gene frequencies change at random by genetic drift, even in the absence of natural selection, was a seminal advance in evolutionary biology. Stochastic drift must also occur in language as a result of randomness in how linguistic forms are copied between speakers. Here we quantify the strength of selection relative to stochastic drift in language evolution. We use time series derived from (...) large corpora of annotated texts dating from the 12th to 21st centuries to analyse three well-known grammatical changes in English: the regularization of past-tense verbs, the introduction of the periphrastic ’do’, and variation in verbal negation. We reject stochastic drift in favour of selection in some cases but not in others. In particular, we infer selection towards the irregular forms of some past-tense verbs, which is likely driven by changing frequencies of rhyming patterns over time. We show that stochastic drift is stronger for rare words, which may explain why rare forms are more prone to replacement than common ones. This work provides a method for testing selective theories of language change against a null model and reveals an underappreciated role for stochasticity in language evolution. (shrink)

We present a historical study of Quantum Technology 2.0 using more than 66,000 papers from 1980 to 2020 that had been assigned to four subfields. We applied the method reference publication year spectroscopy to respective publication sets of the subfields in order to identify their historical roots and seminal papers. We found 126 of them in total, 43 in quantum metrology and sensing, 46 in quantum communication and cryptography, 42 in quantum computing, and 33 in quantum information science–with a significant (...) overlap between subfields–which are all discussed in their relevance for the respective subfield. We compared the subfields regarding their interrelationship and distinctiveness in terms of their most influential papers and were able to deduce a common core set of five seminal publications in all four subfields.

I. EXECUTIVE SUMMARY The MRCT Center Post-trial Responsibilities: Continued Access to an Investigational Medicine Framework outlines a case-based, principled, stakeholder approach to evaluate and guide ethical responsibilities to provide continued access to an investigational medicine at the conclusion of a patient’s participation in a clinical trial. The Post-trial Responsibilities (PTR) Framework includes this Guidance Document as well as the accompanying Toolkit. A 41-member international multi-stakeholder Workgroup convened by the Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard University (...) (MRCT Center) developed this Guidance and Toolkit. Project Motivation A number of international organizations have discussed the responsibilities stakeholders have to provide continued access to investigational medicines. The World Medical Association, for example, addressed post-trial access to medicines in Paragraph 34 of the Declaration of Helsinki (WMA, 2013): “In advance of a clinical trial, sponsors, researchers and host country governments should make provisions for post-trial access for all participants who still need an intervention identified as beneficial in the trial. This information must also be disclosed to participants during the informed consent process.” This paragraph and other international guidance documents converge on several consensus points: • Post-trial access (hereafter referred to as “continued access” in this Framework [for terminology clarification – see definitions]) is the responsibility of sponsors, researchers, and host country governments; • The plan for continued access should be determined before the trial begins, and before any individual gives their informed consent; • The protocol should delineate continued access plans; and • The plan should be transparent to potential participants and explained during the informed consent process. -/- However, there is no guidance on how to fulfill these responsibilities (i.e., linking specific responsibilities with specific stakeholders, conditions, and duration). To fill this gap, the MRCT Center convened a working group in September of 2014 to develop a framework to guide stakeholders with identified responsibilities. This resultant Framework sets forth applicable principles, approaches, recommendations and ethical rationales for PTR regarding continued access to investigational medicines for research participants.

This book's thirty essays explore philosophically the nature and morality of sexual perversion, cybersex, masturbation, homosexuality, contraception, same-sex marriage, promiscuity, pedophilia, date rape, sexual objectification, teacher-student relationships, pornography, and prostitution. Authors include Martha Nussbaum, Thomas Nagel, Alan Goldman, John Finnis, Sallie Tisdale, Robin West, Alan Wertheimer, John Corvino, Cheshire Calhoun, Jerome Neu, and Alan Soble, among others. A valuable resource for sex researchers as well as undergraduate courses in the philosophy of sex.

This volume brings together eminent theologians, philosophers and political theorists to discuss such questions as how religious understandings have shaped the moral landscape of contemporary culture; the possible contributions of theology and theologically informed moral argument to contemporary public life; the problem of religious and moral discourse in a pluralistic society; and the proper relationship between religion and culture.

Despite much research on the relationship between awareness and dementia little can be concluded concerning their relationship and the role of other factors. It is likely that studies capture different phenomena of awareness. This study aimed at identifying and delineating such variation by analysing data from three questionnaires obtained during the longitudinal study of awareness in 101 people with early-stage dementia. The data concerned awareness in relation to memory, activities of daily living and socio-emotional function. Significant differences in patterns of (...) discrepancies were obtained. This suggests that the awareness phenomena involved were structurally different; and that, in turn, this may reflect variation in the intrinsic linking between awareness and its ‘object’ . The identification of such differences is necessary so that appropriate methodologies can be applied to the study of awareness in different contexts. (shrink)

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

Sign language interpreting is a cognitively challenging task performed mostly by second language learners. SLI students must first gain language fluency in a new visuospatial modality and then move between spoken and signed modalities as they interpret. As a result, many students plateau before reaching working fluency, and SLI training program drop-out rates are high. However, we know little about the requisite skills to become a successful interpreter: the few existing studies investigating SLI aptitude in terms of linguistic and cognitive (...) skills lack baseline measures. Here we report a 3-year exploratory longitudinal skills assessments study with British Sign Language -English SLI students at two universities. Our aims were two-fold: first, to better understand the prerequisite skills that lead to successful SLI outcomes; second, to better understand how signing and interpreting skills impact other aspects of cognition. A battery of tasks was completed at four time points to assess skills, including but not limited to: multimodal and unimodal working memory, 2-dimensional and 3-dimensional mental rotation, and English comprehension. Dependent measures were BSL and SLI course grades, BSL reproduction tests, and consecutive SLI tasks. Results reveal that initial BSL proficiency and 2D-MR were associated with selection for the degree program, while visuospatial working memory was linked to continuing with the program. 3D-MR improved throughout the degree, alongside some limited gains in auditory, visuospatial, and multimodal working memory tasks. Visuospatial working memory and MR were the skills closest associated with BSL and SLI outcomes, particularly those tasks involving sign language production, thus, highlighting the importance of cognition related to the visuospatial modality. These preliminary data will inform SLI training programs, from applicant selection to curriculum design. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Josiah Royce: Pragmatist, Ethicist, Philosopher of Religion ed. by Christoph Seibert and Christian PolkeRobin FriedmanJosiah Royce: Pragmatist, Ethicist, Philosopher of Religion Christoph Seibert and Christian Polke, editors. Mohr Siebeck, 2021.In October 2015, the Warburg Haus, Hamburg, held a conference on the American philosopher Josiah Royce that brought together German and American scholars. The papers given at the conference led to this new book, Josiah Royce: Pragmatist, Ethicist, Philosopher (...) of Religion. Edited by the German scholars Christoph Seibert and Christian Polke, the volume includes eleven essays, nine delivered at the 2015 conference, together with additional contributions by Seibert and Polke, the conference organizers.It is valuable to see contemporary German scholars engaging with Royce and to compare their approach with that of American scholars. Americans tend to approach Royce through the tradition of pragmatism in the company of William James, Charles Peirce, and John Dewey, and to minimize the metaphysics in Royce's thought and its idealistic influences. [End Page 116]The book has the goal of developing Royce's thought to show how its insights and concerns may be valuable for contemporary life, not only for scholars of differing philosophical traditions. In their Introduction, Seibert and Polke describe Royce as a "pragmatist of his own kind" (3) and identify three themes in his philosophy. The first is community, which was central to Royce from the beginning and, following his serious study of Peirce, "became the ultimate principle of both his metaphysics and his philosophy of life" (3). The second theme is religion, which, for Royce, involved the "search for the ultimate meaning of his own life, as well as that of his fellows' lives" (3). The third broad theme in Royce is ethics and a lifelong concern with the nature of the examined life. Royce developed his ethical philosophy from an original critique of moral skepticism to the "never-ending task of building communities within and through mankind by way of a critical spirit of true and mutual loyalty" (3). Among these three, the editors consider religion as the most important. They state: "[R]eligion is a very important theme of Royce's philosophy: one may even assume that it is the central subject, which implies that his philosophy may be properly understood only if it is regarded as a philosophy of religion" (8). The centrality of religion is apparent in the essays. Consideration here must be brief.The book's first section, "Bridging Two Continents: Royce between Pragmatism and Idealism," includes three broad-ranging essays that work toward a synthesis between pragmatism and idealism in the thought of Royce. Ludwig Nagl's contribution, "Toward a Global Philosophical Discourse on Religion," discusses Royce's posthumously published "Lectures on Modern Idealism." Nagl uses this work, together with Royce's adaption of Peirce, to help create a bridge between pragmatism and idealism. He further explores Royce's interest in Eastern religion to suggest how Royce's thought might support a broad philosophical study of religion, not restricted to Christianity. Co-editor Seibert's article, "The Ethical Nucleus of Reality," focuses on Royce's epistemology and his ethics, while touching briefly on religion. The essay shows how Royce combined pragmatic and idealistic threads from his earliest writings, with particular attention to his book The Spirit of Modern Philosophy (SM). Royce's SM is also central to the American philosopher Douglas Anderson's essay "What Philosophy Meant to Josiah Royce." In SM, Royce argues that philosophy constitutes a critical reflection on experience that may be practiced by every person, not only by professional philosophers. Anderson, however, also identifies and criticizes a more elitist, professional aspect in Royce's conception of philosophy. For Anderson, Royce's thought had a pragmatist dimension in that philosophy was a "voluntarily chosen attitude toward conducting our lives" (80). Royce's thought also was idealistic [End Page 117] in its recognition of the finite character of human life and in the search for the whole. Anderson writes that, for Royce, "to understand our experiences and to gain some control of our futures, we must see those experiences in their relations to all of what is—no easy task" (80).The book's second section includes...

Paul Thompson argues that current synthetic biology amounts to synthetic genomics, comprising a ‘platform’ technology, and that Christopher Preston's deontological objections based on its supposed rejection of the historical process of evolution miscarry. This makes it surprising that Thompson's normative ethic consists in a deontological appeal to Kantian duties of imperfect obligation. Construed as obligations subject to choice, such constraints risk being excessively malleable where the ethical objections to deployment of this technology concern land rights and/or exploitation. Thompson's advocacy (...) of processes ‘more beneficial’ well illustrates another vulnerability; processes more beneficial than ones that undermine livelihoods could be best avoided themselves, although ones more beneficial than the status quo may not. He well argues that non-deontological arguments should not be confined to human survival, but neglects stances that are either biocentric, consequentialist, or both. Yet a truly synthetic bioethics would be likely to embody these characteristics. (shrink)

Despite the emphasis on moral intuition in the research literature, little attention has been given to the ways in which moral intuition can be educated within management settings (Dane & Pratt 2007). In this paper, I discuss an experiential learning approach that links Robin Hogarth’s (2001, 2008) work on the learning of intuition with Mary Gentile’s (2010) educational program on values-based leadership, Giving Voice To Values (GVV). Building on Hogarth’s proposal that intuitions are primarily acquired and thus shaped by (...) our experiences, GVV offers a pedagogical framework for reflective, experiential learning. Specific attention is given to the themes of learning environments, how these structures shape intuitions, and how students can identify these structures using the GVV emphasis on examination of past experiences.

In an earlier paper Christopher Tuplin and I attempted to establish the date and circumstances of the emergence of the concept of ‘the Greeks of Asia’ and the consequent appearance of ‘the freedom of the Greeks of Asia’ as a political slogan. It was there suggested that concept and slogan first crystallized shortly before the Peace of Antalcidas, and that the freedom of the Greeks of Asia first acquired its full force as a catchword when that freedom had been (...) signed away, apparently for ever. The present paper traces the further history of the slogan, first under Alexander and the Diadochi, then at the time of the Roman conquest of the eastern Mediterranean. No attempt is, however, made to deal with every unanswered question raised by either Macedonian or Roman dealings with Greece. The Greeks of Asia languished under Persia till the time of the Macedonian invasion. Yet when that invasion came, the freedom of the Greeks of Asia was to play little part in Macedonian propaganda, still less in Macedonian practice. The expedition was conceived by Philip as an act of revenge for the Persian invasions of Greece. This theme of revenge was taken up by Alexander at the time of his appointment to command, and recurs in his letter to Darius and his words to Parmenio after the taking of Persepolis. The even broader theme of a crusade of Greeks against Persians to achieve the conquest of Asia is still more frequent. It dictates the sedulous manufacture of parallels with the Trojan war and the inscription on the spoils sent to Athens after the battle of the Granicus; it was also used to justify Alexander's hatred of Greeks who fought on the Persian side. By comparison with these motifs the freedom of the Greeks of Asia receives little attention. When Philip sent out his advance expedition under Parmenio and Attalus, his instructions to them were to free the Greek cities. But just how flexibly that order could be interpreted is shown by Parmenio's treatment of Grynium. Alexander too showed himself ruthlessly pragmatic in his attitude to Greek cities, until the appointment of Alcimachus to liberate the Aeolian and Ionian cities. Yet this development receives little attention in the sources, and the only trace of it in subsequent propaganda is the claim ascribed to Alexander when he was on his way from Miletus to Caria that he had undertaken the war for the sake of the freedom of the Greeks, the only occasion in the surviving evidence on which Alexander makes this assertion.

Nietzsche repeatedly portrays himself as an advocate of what he calls a ‘philosophy of becoming’. While in his early Untimely Meditations he had considered the ‘doctrine of sovereign becoming’ to be ‘true but deadly’, from the middle-period Human, All Too Human up to and including his last writings he urges us to embrace this doctrine wholeheartedly. He consistently links the view of the world as being in a state of constant flux with the teachings of Heraclitus, the one philosopher whom (...) he praises to the very end of his sane life. Exactly what such a doctrine amounts to is a question that has not hitherto been subjected to the substantial treatment that it deserves, and it is this issue that Robin Small sets out to address.

Motivated by aspects of reasoning in theories of physics, Robin Giles defined a characterization of infinite valued Łukasiewicz logic in terms of a game that combines Lorenzen-style dialogue rules for logical connectives with a scheme for betting on results of dispersive experiments for evaluating atomic propositions. We analyze this game and provide conditions on payoff functions that allow us to extract many-valued truth functions from dialogue rules of a quite general form. Besides finite and infinite valued Łukasiewicz logics, also (...) Meyer and Slaney’s Abelian logic and Cancellative Hoop Logic turn out to be characterizable in this manner. (shrink)

This is an obituary for Michael H. Robins.

Robin McKenna argues that we need to make space for an approach to epistemology that avoids the idealizations typical of the field. He applies this approach to topics in applied and social epistemology, such as what to do about science denial, whether we should try to be intellectually autonomous, and what our obligations are to other inquirers.

This book, first published in 1981, provides a penetrating and lucid introduction to the philosophy of education. The emphasis on schooling rather than education draws attention to the broad spectrum of the book: recognising that schools generally do more than educate, Dr. Barrow specifically addresses himself to the larger question of what schools are for and what they should do. This book will be of interest both to students of philosophy and students of education.

A model for the ideal state includes discussion of the nature and application of justice, the role of the philosopher in society, the goals of education, and the effects of art upon character.

Many of us hold false beliefs about matters that are relevant to public policy such as climate change and the safety of vaccines. What can be done to rectify this situation? This question can be read in two ways. According to the descriptive reading, it concerns which methods will be effective in persuading people that their beliefs are false. According to the normative reading, it concerns which methods we are permitted to use in the service of persuading people. Some effective (...) methods—a programme of brainwashing, say—would not be permissible. In this paper I compare “methods of rational persuasion” with what you might call “marketing methods” such as how one frames the problem of climate change. My aim is to show that “marketing methods” are preferable to “methods of rational persuasion”. My argument has two parts. First, I argue that the evidence suggests that “marketing methods” are more effective in persuading people to change their minds. Second, I argue that “marketing methods” are an acceptable response to the normative question. (shrink)
