This article contains my response to the commentaries by Mazviita Chirimuuta, Tom Froese, Miriam Kyselo, and Claudia E. Vanney on The Blind Spot: Why Science Cannot Ignore Human Experience (Frank et al., 2024 ).
The pursuit of a scientific theory of consciousness has gained momentum in neuroscience over the past 25 years. While much research has centered on perceptual consciousness, the dynamic experience of the stream of thought, proposed by William James over a century ago, has remained relatively underexplored. The Dynamic Framework of Thought (DFT) introduced a taxonomy of thought dynamics,...
One of the most striking features of human consciousness is its ability to foster an ongoing, seemingly continuous stream of thought. Prior studies have provided valuable insights into the neural correlates of the content of thought (e.g., whether it is task related or not). However, independent of its content, the stream of thought can also be characterized by its dynamics—how it changes over...

Research on the specific features of daydreaming compared with mind-wandering and night dreaming is a neglected topic in the philosophy of mind and the cognitive neuroscience of spontaneous thought. The extant research either conflates daydreaming with mind-wandering (whether understood as task-unrelated thought, unguided attention, or disunified thought), characterizes daydreaming as opposed...
Abstract Meditation is trending right now. From classrooms and hospitals to business meetings and phone apps, our culture is enthralled by meditation as a powerful tool to train our brains and shape our private mental lives—to make us happier, more productive, and more peaceful on the inside. But meditation is not just about training our brains. It’s a deeply social—and fundamentally...
Despite increasing scientific interest in self-generated thought-mental content largely independent of the immediate environment-there has yet to be any comprehensive synthesis of the subjective experience and neural correlates of affect in these forms of thinking. Here, we aim to develop an integrated affective neuroscience encompassing many forms of self-generated thought-normal and...
This chapter provides an introduction to the philosophy of mind-wandering. It begins with a philosophical critique of the standard psychological definitions of mind-wandering as task-unrelated thought or stimulus-independent thought. Although these definitions have helped bring mind-wandering research onto center stage in psychology and cognitive neuroscience, they have substantial limitations....
Dynamic and static body postures are a defining characteristic of mind-body practices such as Tai Chi and Qigong (TCQ). A growing body of evidence supports the hypothesis that TCQ may be beneficial for psychological health, including management and prevention of depression and anxiety. Although a variety of causal factors have been identified as potential mediators of such health benefits,...
This paper is a commentary on Dan Arnold's book, Brains, Buddhas, and Believing: The Problem of Intentionality in Classical Buddhist and Cognitive-Scientific Philosophy of Mind, presented at the Toshide Numata Book Prize Symposium, "Taking Buddhist Philosophy of Mind Seriously," University of California, Berkeley, November 15, 2013.
This paper is the text of a keynote lecture for the conference "Buddhism, Mind, and Cognitive Science" at the University of California, Berkeley, April 25, 2014. The main proposition is that the Buddhism-cognitive science encounter needs to be fundamentally reoriented in order to have a chance of becoming a genuine dialogue. At present, the encounter takes its direction from scientific research...
A necessary first step in collaboration between hypnosis research and meditation research is clarification of key concepts. The authors propose that such clarification is best advanced by neurophenomenological investigations that integrate neuroscience methods with phenomenological models based on first-person reports of hypnotic versus meditative experiences. Focusing on absorption, the...
We argue that the minimal biological requirements for consciousness include a living body, not just neuronal processes in the skull. Our argument proceeds by reconsidering the brain-in-a-vat thought experiment. Careful examination of this thought experiment indicates that the null hypothesis is that any adequately functional “vat” would be a surrogate body, that is, that the so-called vat would...
Author's précis of Waking, Dreaming, Being: Self and Consciousness in Neuroscience, Meditation, and Philosophy, including the author's response to commentators.
Cognitive neuroscience tends to conceptualize mindfulness meditation as inner observation of a private mental realm of thoughts, feelings, and body sensations, and tries to model mindfulness as instantiated in neural networks visible through brain imaging tools such as EEG and fMRI. This approach confuses the biological conditions for mindfulness with mindfulness itself, which, as classically...
This chapter explains embodied action. The term embodied highlights two points: first, that cognition depends upon the kinds of experience that come from having a body with various sensorimotor capacities, and second, that these individual sensorimotor capacities are themselves embedded in a more encompassing biological, psychological, and cultural context. The term action emphasizes that...
Consciousness is often said to disappear in deep, dreamless sleep. We argue that this assumption is oversimplified. Unless dreamless sleep is defined as unconscious from the outset there are good empirical and theoretical reasons for saying that a range of different types of sleep experience, some of which are distinct from dreaming, can occur in all stages of sleep. We introduce a novel...
Thoughts arise spontaneously in our minds with remarkable frequency, but tracking the brain systems associated with the early inception of a thought has proved challenging. Here we addressed this issue by taking advantage of the heightened introspective ability of experienced mindfulness practitioners to observe the onset of their spontaneously arising thoughts. We found subtle differences in...
Current research on spontaneous, self-generated brain rhythms and dynamic neural network coordination cast new light on Immanuel Kant's idea of the 'spontaneity' of cognition, that is, the mind's capacity to organize and synthesize sensory stimuli in novel, unprecedented ways. Nevertheless, determining the precise nature of the brain-cognition mapping remains an outstanding challenge....
One of the major debates in classical Indian philosophy concerned whether consciousness is present or absent in dreamless sleep. The philosophical schools of Advaita Vedānta and Yoga maintained that consciousness is present in dreamless sleep, whereas the Nyāya school maintained that it is absent. Consideration of this debate, especially the reasoning used by Advaita Vedānta to rebut the Nyāya...
The study of consciousness was banished from respectable science with the rise of behaviorism in the early 20th century. Beginning in the 1980s, however, researchers in cognitive science began to return to the topic (e.g., Baars, 1988; Chalmers, 1996; Crick & Koch, 1990; Dennett, 1991), In recent decades, there has been an explosion of research on the neurophysiological processes underlying...
Recent advances in brain imaging have improved the measure of neural processes related to perceptual, cognitive and affective functions, yet the relation between brain activity and subjective experience remains poorly characterized. In part, it is a challenge to obtain reliable accounts of participant's experience in such studies. Here we addressed this limitation by utilizing experienced...
The accuracy of subjective reports, especially those involving introspection of one's own internal processes, remains unclear, and research has demonstrated large individual differences in introspective accuracy. It has been hypothesized that introspective accuracy may be heightened in persons who engage in meditation practices, due to the highly introspective nature of such practices. We...
Moderated by Krista Tippett, creator and host of America Public Media's On Being, philosophers Thomas Metzinger (University of Mainz, Germany) and Evan Thompson (University of Toronto) join cardiologist and expert on near-death experiences Pim van Lommel (Hospital Rijnstate, the Netherlands) to examine recent developments in neuroscience and philosophy that shed light on whether our conscious...
This chapter discusses the brain-in-a-vat thought experiment and attempts to determine what needs to be specified so that one can properly imagine a brain in a vat. Daniel Dennett notes that philosophers often fail to set up their intuition pumps properly by failing to think carefully about the requirements and implications of their imagined scenarios. His suggestion is considered here and a...
