Powerful conversations between His Holiness the Dalai Lama and leading scientists on the most pressing issue of our time. Engage with leading scientists, academics, ethicists, and activists, as well as His Holiness the Dalai Lama and His Holiness the Karmapa, who gathered in Dharamsala, India, for the twenty-third Mind and Life conference to discuss arguably the most urgent questions facing humanity today: What is happening to our planet? What can we do about it? How do we balance the concerns of (...) people against the rights of animals and against the needs of an ecosystem? What is the most skillful way to enact change? And how do we fight on, even when our efforts seem to bear no fruit? Inspiring, edifying, and transformative, this should be required reading for any citizen of the world. (shrink)

Evan Thompson’s Waking, Dreaming, Being is an outstanding work that richly deserves the widespread praise that it is receiving. The book exhibits exquisite balance between various poles: science and philosophy, “East” and “West,” the accessible and the specialized, the physical and the emergent, and so on. It is also a remarkably readable book, and since academic literature is littered with many unreadable must-read tomes, I am grateful for the change of pace. In short, those who have not yet read Waking, (...) Dreaming, Being should be heartily encouraged to do so.

The essays that follow grew out of a workshop held at the Center for Buddhist Studies, University of California, Berkeley, in March 2018, on the topic of conceptuality and non-conceptuality in Buddhist philosophy. Discussions at the workshop focused specifically on the tenability of the claim made by the two Buddhist epistemologists Dignāga and Dharmakīrti that perceptual cognitions are non-conceptual and yet also contribute to the contents of conceptual thought. The four contributions collected here present just a few of the resulting (...) reflections.This essay explores the Dharmakīrtian1 notion of a "concept" in the specific context of a "pseudo-perception", that is, cognitive events that...

The overall goal of this essay is to explore the initial findings of neuroscientific research on meditation; in doing so, the essay also suggests potential avenues of further inquiry. The essay consists of three sections that, while integral to the essay as a whole, may also be read independently. The first section, “Defining Meditation,” notes the need for a more precise understanding of meditation as a scientific explanandum. Arguing for the importance of distinguishing the particularities of various traditions, the section (...) presents the theory of meditation from the paradigmatic perspective of Buddhism, and it discusses the difficulties encountered when working with such theories. The section includes an overview of three practices that have been the subject of research, and it.. (shrink)

The Buddhist epistemologist Dharmakīrti (fl. ca. 7th century C.E.) developed a theory of yogic perception that achieved much influence among Buddhist thinkers in India and Tibet. His theory includes an odd problem: on Dharmakīrti’s view, many of the paradigmatic objects of the adept’s meditations do not really exist. How can one cultivate a meditative perception of the nonexistent? This ontological difficulty stems from Dharmakīrti’s decision to construe the Four Noble Truths as the paradigmatic objects of yogic perception. For him, this (...) ontological problem manifests in an epistemological corollary: “impermanence” (anityatā) and other features of the Noble Truths are conceptual, but the adept’s meditative perception of them must be nonconceptual. How can a nonconceptual cognition apprehend a conceptual object? A key aspect of Dharmakīrti’s theory of concepts provides a solution to this problem. Specifically, Dharmakīrti maintains that a concept, when taken as a mental event, can be considered a particular and thus an object of nonconceptual cognition. Taking this approach, Dharmakīrti downplays the notion that yogic perception is an encounter with real things in the world, in part because it is phenomenally akin to hallucination. Instead, what counts for Dharmakīrti—and what differentiates the adept’s realization from the madman’s hallucination—are the salvific effects induced by the meditative experience. (shrink)

Recent EEG studies on the early postmortem interval that suggest the persistence of electrophysiological coherence and connectivity in the brain of animals and humans reinforce the need for further investigation of the relationship between the brain’s activity and the dying process. Neuroscience is now in a position to empirically evaluate the extended process of dying and, more specifically, to investigate the possibility of brain activity following the cessation of cardiac and respiratory function. Under the direction of the Center for Healthy (...) Minds at the University of Wisconsin-Madison, research was conducted in India on a postmortem meditative state cultivated by some Tibetan Buddhist practitioners in which decomposition is putatively delayed. For all healthy baseline and postmortem subjects presented here, we collected resting state electroencephalographic data, mismatch negativity, and auditory brainstem response. In this study, we present HB data to demonstrate the feasibility of a sparse electrode EEG configuration to capture well-defined ERP waveforms from living subjects under very challenging field conditions. While living subjects displayed well-defined MMN and ABR responses, no recognizable EEG waveforms were discernable in any of the tukdam cases. (shrink)

One of the most dominant approaches to semantics for relevant (and many paraconsistent) logics is the Routley-Meyer semantics involving a ternary relation on points. To some (many?), this ternary relation has seemed like a technical trick devoid of an intuitively appealing philosophical story that connects it up with conditionality in general. In this paper, we respond to this worry by providing three different philosophical accounts of the ternary relation that correspond to three conceptions of conditionality. We close by briefly discussing (...) a general conception of conditionality that may unify the three given conceptions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Learning in Dramatic and Virtual Worlds:What Do Students Say About Complementarity and Future Directions?John O'Toole (bio) and Julie Dunn (bio)A top financial backer has arrived to determine which team of computer interaction designers has developed the most exciting and innovative proposal for the Everest component of the Virtually Impossible Computer Company's Conquerors of the World Series. Tension is high as the presentations begin, but this tension soon turns (...) to outright conflict as some proposals suggest George Mallory as the conqueror, and the financial backer will have none of him. The backer, it seems, has her own agenda and is determined to allow for only one view of history—the one that records Sir Edmund Hillary as a New Zealand hero and the only real conqueror of the tallest mountain on earth. The designers become more and more agitated until suddenly someone bangs their hand on the table and calls out, "Hang on... just because you've got the money doesn't mean... kids need to learn about both these men... they need to learn about history." With that the drama is cut by the teacher. The deep understandings about "history's purchased page" that can be generated when drama and computers are brought together for learning have been made explicit... but could these same outcomes have been achieved using just one of these approaches?IntroductionThe research explored within this article was generated as part of the Media Station, a project funded by the Australasian Collaborative Research Centre for Interaction Design (ACID), with an overall mission to investigate the potential of massively multiplayer online games for learning. This particular subproject, History's Purchased Page, saw researchers from interaction design [End Page 89] and drama education come together with a group of young learners to investigate their perceptions of the complementarity of computers and live classroom drama and to brainstorm future possibilities for applying computer-based technologies to drama-based learning. We sought to discover the following:• What do young learners say about how they experience and value learning in a context involving a combination of drama and computers?• What ideas do these young learners have about how future technologies might enrich the complementarity of this combination?As the drama researchers involved in this project, we had been experimenting with this perhaps slightly unusual combination for over a decade by incorporating computers into a number of our drama units within our primary textbook Pretending to Learn.1 Our goal in these experimentations had always been to enrich the classroom drama experience by taking advantage of the information capacity of the Internet and other computer-based resources, including databases. For example, we had used The First Fleet Database2 to support a drama unit where the learners take on the role of convicts arriving in Australia in 1788. We discovered that this material, combined with other documentation and historical materials available via the Internet, greatly enhanced not only the historical accuracy of the work but also the level of engagement experienced by the learners when in role. Therefore, we were very keen to extend this work by exploring new possibilities and were especially keen to develop a better understanding of what the learners made of this interactivity.In recent years the partnering of these two quite different approaches to learning has developed quite a research following, and a number of drama teachers and researchers have become interested in the complementarity of these ways of learning.3 At the same time, researchers and designers from the field of computer-assisted learning have also noted these connections. This goes back to the work of Brenda Laurel, who first drew attention to the intriguing links between computers and theatre in her now famous text Computers as Theatre.4 With the rapid growth of interactive learning tools such as 3-D immersive worlds, blogs, and online voice and text chat spaces, the opportunities for exploration of these connections have also grown, with each of these offering exciting new possibilities when used in conjunction with the highly interactive and engaging strategies of process drama.Process drama is a way of group learning, through whole-class improvised drama, with students (and sometimes the...

Loneliness in medicine is a serious problem not just for patients, for whom illness is intrinsically isolating, but also for physicians in the contemporary condition of medicine. We explore this problem by investigating the ideal physician-patient relationship, whose analogy with friendship has held enduring normative appeal. Drawing from Talbot Brewer and Nir Ben-Moshe, we argue that this appeal lies in a dynamic form of companionship incompatible with static models of friendship-like physician-patient relationships: a mutual refinement of embodied virtue that draws (...) both persons together. The ideal physician-patient relationship has a dialectical character that fosters each member's improvement of phenomenologically recognizing and embodying moral virtues. A key component of this dynamic is a commitment to the common goal of the patient's health, realized through joint interactivities and conversations over time. The physician's presence to the patient's suffering—understood best as an alienating phenomenological condition for the patient—orients and discloses possibilities for virtuous caregiving by structuring the meanings of the goals, conversations, and joint narrative constitutive of their relationship. Presence to suffering, paradoxically, is perhaps an important prerequisite for this dynamic partnership. These activities dialectically build an interpretive horizon of understanding through which moral goods and character refinement—in and for the other—may become revealed for both persons in their shared being-in-the-world. This analysis of suffering, mood, and revealing of (possible) moral goods has implications for addressing the modern problem of loneliness for patients and physicians, who are increasingly inhibited from building flourishing relationships with each other.

There are some paradoxes in the way doctors and patients make medical decisions today. Today's patients are more empowered than were patients in the past. They have the right to see their medical records. The law requires doctors to obtain their informed consent for treatment. Patients are told about the options for treatment and the risks and benefits of each option. Their values and preferences are elucidated in order to guide the treatments that are provided.

What to Believe? is an engaging introduction to radical theology for spiritual seekers, "Nones," and others outside the academy as well as students in philosophy, religion, and theology departments who are curious about what religion can mean today, 60 years after the revolutionary "death of God" movement. Radical theology is post-theism--atheism about theism. Rather than a personal God, we personify God--we give a name to sense of meaning that we cannot name as an act of imagination, a reflection of an (...) idea that is not supernatural but resonant within human consciousness and the world at large and available through works of art or scientific encounters. It negates typical binaries like religious and secular, theist and atheist, faithful and rational. For Caputo, God is not a question about the existence of a being but rather a question about the worth of the world. (shrink)

Ever since Copernicus, scientists have continually adjusted their view of human nature, moving it further and further from its ancient position at the center of Creation. But in recent years, a startling new concept has evolved that places it more firmly than ever in a special position. Known as the Anthropic Cosmological Principle, this collection of ideas holds that the existence of intelligent observers determines the fundamental structure of the Universe. In its most radical version, the Anthropic Principle asserts that (...) "intelligent information-processing must come into existence in the Universe, and once it comes into existence, it will never die out." This wide-ranging and detailed book explores the many ramifications of the Anthropic Cosmological Principle, covering the whole spectrum of human inquiry from Aristotle to Z bosons. Bringing a unique combination of skills and knowledge to the subject, John D. Barrow and Frank J. Tipler--two of the world's leading cosmologists--cover the definition and nature of life, the search for extraterrestrial intelligence, and the interpretation of the quantum theory in relation to the existence of observers. The book will be of vital interest to philosophers, theologians, mathematicians, scientists, and historians, as well as to anyone concerned with the connection between the vastness of the universe of stars and galaxies and the existence of life within it on a small planet out in the suburbs of the Milky Way.

The inaugural title in the new, Open Access series BSPS Open, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference. The fundamental burden of a theory of inductive inference is to determine which are the good inductive inferences or relations of inductive support and why it is that they are so. The traditional approach is modeled on that taken in accounts of deductive inference. It seeks universally applicable schemas or rules or a single (...) formal device, such as the probability calculus. After millennia of halting efforts, none of these approaches has been unequivocally successful and debates between approaches persist. The Material Theory of Induction identifies the source of these enduring problems in the assumption taken at the outset: that inductive inference can be accommodated by a single formal account with universal applicability. Instead, it argues that that there is no single, universally applicable formal account. Rather, each domain has an inductive logic native to it. Which that is, and its extent, is determined by the facts prevailing in that domain. Paying close attention to how inductive inference is conducted in science and copiously illustrated with real-world examples, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference.

The Birth of American Law: An Italian Philosopher and the American Revolution tells the forgotten, untold story of the origins of U.S. law. Before the Revolutionary War, a 26-year-old Italian thinker, Cesare Beccaria, published On Crimes and Punishments, a runaway bestseller that shaped the Declaration of Independence, the U.S. Constitution, and early American laws. America's Founding Fathers, including early U.S. Presidents, avidly read Beccaria's book--a product of the Italian Enlightenment that argued against tyranny and the death penalty. Beccaria's book shaped (...) American views on everything from free speech to republicanism, to "Life, Liberty and the pursuit of Happiness," to gun ownership and the founders' understanding of "cruel and unusual punishments," the famous phrase in the U.S. Constitution's Eighth Amendment. In opposing torture and infamy, Beccaria inspired America's founders to jettison England's Bloody Code, heavily reliant on executions and corporal punishments, and to adopt the penitentiary system. The cast of characters in The Birth of American Law includes the usual suspects--George Washington, Thomas Jefferson, John Adams and James Madison. But it also includes the now little-remembered Count Luigi Castiglioni, a botanist from Milan who--decades before Alexis de Tocqueville's Democracy in America--toured all thirteen original American states before the 1787 Constitutional Convention in Philadelphia. Also figuring in this dramatic story of the American Revolution: Madison's Princeton classmate William Bradford, an early U.S. Attorney General and Beccaria devotee; John Dickinson, the "Penman of the Revolution" who wrote of Beccaria's "genius" and "masterly hand"; James Wilson and Dr. Benjamin Rush, signers of the Declaration of Independence and fellow Beccaria admirers; and Philip Mazzei, Jefferson's Italian-American neighbor at Monticello and yet another Beccaria enthusiast. In documenting Beccaria's game-changing influence, The Birth of American Law sheds important new light on the Constitution, the Bill of Rights, and the creation of American law. This book is part of the Legal History Series, edited by H. Jefferson Powell, Duke University School of Law. The Birth of American Law was awarded the 2015 Scribes Book Award and the First Prize in the 2015 AAIS Book Award competition (in the 18th/19th century category). It was also named INDIEFAB's 2014 Gold Winner for History! (shrink)

An infinite lottery machine is used as a foil for testing the reach of inductive inference, since inferences concerning it require novel extensions of probability. Its use is defensible if there is some sense in which the lottery is physically possible, even if exotic physics is needed. I argue that exotic physics is needed and describe several proposals that fail and at least one that succeeds well enough.

It is proposed that we use the term “approximation” for inexact description of a target system and “idealization” for another system whose properties also provide an inexact description of the target system. Since systems generated by a limiting process can often have quite unexpected, even inconsistent properties, familiar limit systems used in statistical physics can fail to provide idealizations, but are merely approximations. A dominance argument suggests that the limiting idealizations of statistical physics should be demoted to approximations.

Contrary to formal theories of induction, I argue that there are no universal inductive inference schemas. The inductive inferences of science are grounded in matters of fact that hold only in particular domains, so that all inductive inference is local. Some are so localized as to defy familiar characterization. Since inductive inference schemas are underwritten by facts, we can assess and control the inductive risk taken in an induction by investigating the warrant for its underwriting facts. In learning more facts, (...) we extend our inductive reach by supplying more localized inductive inference schemes. Since a material theory no longer separates the factual and schematic parts of an induction, it proves not to be vulnerable to Hume's problem of the justification of induction. (shrink)

Context Conflicts over treatment decisions have been linked to physicians' emotional states. Objective To measure the prevalence of emotional exhaustion and conflicts over treatment decisions among US obstetrician/gynaecologists (ob/gyns), and to examine the relationship between the two and the physician characteristics that predict each. Methods Mailed survey of a stratified random sample of 1800 US ob/gyn physicians. Criterion variables were levels of emotional exhaustion and frequency of conflict with colleagues and patients. Predictors included physicians' religious characteristics and self-perceived empathy. Results (...) Response rate among eligible physicians was 66% (1154/1760). 36% of ob/gyns reported high levels of emotional exhaustion, and majorities reported conflict with colleagues (59%) and patients (61%). Those reporting conflict were much more likely to report emotional exhaustion (58% vs 29% who never conflict, OR, 95% CI 2.8, 1.6 to 4.8 for conflict with colleagues; 55% versus 26%, OR, 95% CI 2.2, 1.4 to 3.5 for conflict with patients). Physicians with lower self-perceived empathy were more likely to report physician-patient conflicts (65% vs 58% with higher empathy, OR, 95% CI 1.4, 1.0 to 1.9), as were female ob/gyns (66% vs 57% of males, OR, 95% CI 1.5, 1.1 to 2.0). Foreign-born physicians were less likely to report such conflicts (47% vs 64% of US born, OR, 95% CI 0.5, 0.4 to 0.8). Physicians' religious characteristics were not significantly associated with reporting conflict. Conclusions Conflicts over treatment decisions are associated with physicians' empathy, gender, immigration history and level of emotional exhaustion. With respect to the latter, conflict in the clinical encounter may represent an overlooked source or sign of burnout among ob/gyns. (shrink)

I deny that the world is fundamentally causal, deriving the skepticism on non-Humean grounds from our enduring failures to find a contingent, universal principle of causality that holds true of our science. I explain the prevalence and fertility of causal notions in science by arguing that a causal character for many sciences can be recovered, when they are restricted to appropriately hospitable domains. There they conform to a loose collection of causal notions that form a folk science of causation. This (...) recovery of causation exploits the same generative power of reduction relations that allows us to recover gravity as a force from Einstein's general relativity and heat as a conserved fluid, the caloric, from modern thermal physics, when each theory is restricted to appropriate domains. Causes are real in science to the same degree as caloric and gravitational forces. (shrink)

Newton’s equations of motion tell us that a mass at rest at the apex of a dome with the shape specified here can spontaneously move. It has been suggested that this indeterminism should be discounted since it draws on an incomplete rendering of Newtonian physics, or it is “unphysical,” or it employs illicit idealizations. I analyze and reject each of these reasons. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, Pittsburgh, PA (...) 15260; e‐mail: [email protected].

In a formal theory of induction, inductive inferences are licensed by universal schemas. In a material theory of induction, inductive inferences are licensed by facts. With this change in the conception of the nature of induction, I argue that the celebrated “problem of induction” can no longer be set up and is thereby dissolved. Attempts to recreate the problem in the material theory of induction fail. They require relations of inductive support to conform to an unsustainable, hierarchical empiricism.

The epistemic state of complete ignorance is not a probability distribution. In it, we assign the same, unique, ignorance degree of belief to any contingent outcome and each of its contingent, disjunctive parts. That this is the appropriate way to represent complete ignorance is established by two instruments, each individually strong enough to identify this state. They are the principle of indifference (PI) and the notion that ignorance is invariant under certain redescriptions of the outcome space, here developed into the (...) ‘principle of invariance of ignorance' (PII). Both instruments are so innocuous as almost to be platitudes. Yet the literature in probabilistic epistemology has misdiagnosed them as paradoxical or defective since they generate inconsistencies when conjoined with the assumption that an epistemic state must be a probability distribution. To underscore the need to drop this assumption, I express PII in its most defensible form as relating symmetric descriptions and show that paradoxes still arise if we assume the ignorance state to be a probability distribution. *Received February 2007; revised July 2007. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, Pittsburgh, PA 15260; e-mail: [email protected].

Thought experiments are ordinary argumentation disguised in a vivid pictorial or narrative form. This account of their nature will allow me to show that empiricism has nothing to fear from thought experiments. They perform no epistemic magic. In so far as they tell us about the world, thought experiments draw upon what we already know of it, either explicitly or tacitly; they then transform that knowledge by disguised argumentation. They can do nothing more epistemically than can argumentation. I defend my (...) account of thought experiments in Section 3 by urging that the epistemic reach of thought experiments turns out to coincide with that of argumentation and that this coincidence is best explained by the simple view that thought experiments just are arguments. Thought experiments can err—-a fact to be displayed by the thought experiment - anti thought experiment pairs of Section 2. Nonetheless thought experiments can be used reliably and, I urge in Section 4., this is only possible if they are governed by some very generalized logic. I will suggest on evolutionary considerations that their logics are most likely the familiar logics of induction and deduction, recovering the view that thought experiment is argumentation. Finally in Section 5 I defend this argument based epistemology of thought experiments against competing accounts. I suggest that these other accounts can offer a viable epistemology only insofar as they already incorporate the notion that thought experimentation is governed by a logic, possibly of very generalized form.
