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)

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. They will find the task a pleasant and edifying one.Much more could be said in praise of Waking, Dreaming, Being, but the task here is to offer some... (shrink)

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...

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)

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)
