Toward a neurophysiological foundation for altered states of consciousness

Singh's cultural evolutionary theory posits that methods of inducing shamanic altered states of consciousness differ, resulting in profoundly different cognitive states. We argue that, despite different methods of induction, altered states of consciousness share neurophysiological features and cause shared cognitive and behavioral effects. This common foundation enables further cross-cultural comparison of shamanic activities that is currently left out of Singh's theory

Too much attention, too little self

This is a good time for such a substantial book on Buddhaghosa. His ideas may be more difficult to digest than those of contemporary authors, but Ganeri convincingly argues for their relevance. Together with Ganeri’s considerable interpretive and philosophical work, Buddhaghosa’s view helps to fill out a perspective that is popular in cognitive science, in which the self is replaced by systems. In this case, the self is replaced by systems of attention, a view that Ganeri calls ‘Attentionalism.’ In this review I will focus on two aspects of the account that I find especially puzzling, with the hope that this leads to further elucidation, whether by Ganeri or others. Specifically, I will focus on the concepts of ekaggatā, or “placing,” and anatta, or “no-self,” as interpreted by Ganeri

Practical Realism about the Self

In Explaining Attitudes, Baker argues that we should treat our everyday practices as relevant to metaphysical debates, resulting in a stance of realism with respect to intentional explanations. In this chapter I will argue that if one is going to be a practical realist about anything, it should be the self, or subject of attention. I will use research on attention combined with the stance of practical realism to argue in favor of a substantive self. That is, I will present an account of the self that directs and controls attention, in line with our everyday view of the self. I will contrast this account with what I call the “illusion view,” which presents the self and its apparent causal power in the case of attention as an illusion. My account of the self will make use of several of Baker's ideas, including non-reductive materialism and broad supervenience

The Philosophical Landscape on Attention

Attention has a long history in philosophy, despite its near absence in the twentieth century. This chapter provides an overview of philosophical research on attention. It begins by explaining the concept of "selection from limitation," contrasting it with the more recent "selection for action." It reviews historical texts that discuss attention, focusing on those in the Western canon whose understanding of "attention" aligns with contemporary usage. It then describes the differential treatment of attention in phenomenology and behaviorism in the last century. Finally, it discusses contemporary research by topic: attention, perception, and knowledge; attention and consciousness; attention and action; and attention and the self. It includes work by Allport,Aristotle, Astell, Augustine, Bergson, Berkeley, Block, Bradley, Buddhaghosa, Campbell, Cherry, De Brigard, Dehaene and Naccache, Descartes, Dickie, Du Bois, Ganeri, Hegel, Heidegger, James, Kant, Koch and Tsuchiya, LaBerge, Locke, Mack and Rock, Malebranche, Merleau-Ponty, Mole, Montemayor and Haladjian, Neumann, Pashler, Posner, Prinz, Reid, Rensink, Reynolds and Heeger, Treisman, Watzl, Wittgenstein, Wollstonecraft, and Wu

Contextual Emergence

Contextual emergence is a relatively simple but disruptive concept. It undermines the claim that emergence is necessarily a form of supervenience, often repeated by philosophers. It bucks the “false forced choice” between weak and strong emergence. It is scientifically grounded but challenges the prevailing reductive worldview in science. It has much to recommend a detailed philosophical treatment, such as this one. This book is thus a welcome treatise on a timely topic

Consciousness and Mind

Some of the oldest and deepest questions in philosophy fall under the umbrella of consciousness and mind: What is the mind and how is it related to the body? What provides our thoughts with content? How is consciousness related to the natural world? Do we have distinctive causal powers? Analytic philosophers have made significant progress on these and related problems in the last century. Given the high volume of work on such topics, this chapter is necessarily selective. It offers major touchstones but is slanted in favor of work that touches base with the sciences. The chapter starts by describing the progression of thought on the mind-body problem, from dualism and behaviorism to non-reductive materialism. It then describes the problem of intentionality, with a focus on partial solutions from Dretske and Millikan, ending with a brief discussion of 4E theories of mental content. The section on the problem of consciousness starts with the well-known knowledge and modal arguments before describing some attempted initial solutions, such as eliminative materialism and panpsychism. Finally, there is a brief section on agency and free will, which focuses on the link between free will and consciousness

STUDIES ON THE NONSPECIFIC DEPRESSION OF THE IMMUNE RESPONSE

Calf serum has been shown to suppress the primary immune response to erythrocytes and some bacterial antigens in mice if administered prior to and not after immunization. The importance of the route of iniection of antigens and immunosuppressant is indicated. It is suggested that immunosuppression is achieved by phagocytosis and enyzmatic destruction of the injected antigen by peritoneal macrophages. A similar mechanism is probably involved in the type of immunosuppression induced by PHA

The Diversity and Inclusivity Survey: Final Report

In 2018 Academic Placement Data and Analysis ran a survey of doctoral students and recent graduates on the topics of diversity and inclusivity in collaboration with the Graduate Student Council and Data Task Force of the American Philosophical Association. We submitted a preliminary report in Fall 2018 that describes the origins and procedure of the survey [1]. This is our final report on the survey. We first discuss the demographic profile of our survey participants and compare it to the United States general population, its doctoral students, and APA membership, finding several areas of underrepresentation (i.e. gender, race/ethnicity, socioeconomic, and veteran status). We then discuss the results of questions regarding diversity and inclusivity. We find, for instance, that participant comfort in philosophy depends on gender, sexuality, race/ethnicity, disability, and language status and that participants most often mentioned the theme of diversity when asked how philosophy could be more inclusive. Finally, we discuss the results of questions related to graduate program and placement. We find, for example, that underrepresented graduates are both less likely to recommend their graduate program to others and less likely to prefer an academic job. We close by making some recommendations for the APA and for the discipline based on our findings
