Based on Pritchard’s distinction (2012, 2016) between favoring and discriminating epistemic grounds, and on how those grounds bear on the elimination of skeptical possibilities, I present the dream argument as a moderate skeptical possibility that can be reasonably motivated. In order to block the dream argument skeptical conclusion, I present a version of phenomenological disjunctivism based...

In normal circumstances we can easily distinguish between changes to the external world brought about by our own actions from those with external causes. However, in certain contexts our sense of ownership and agency over acts is not so clear. Neuroimaging studies have implicated a number of regions in the sense of agency, some of which have been shown to vary continuously with action-outcome...

Recreational use of Synthetic Cannabinoid Receptors Agonists (SCRAs) has become increasingly common in many countries and may cause severe toxic effects. To describe the clinical features of toxicity in seven men after analytically confirmed exposure to MDMB-CHMICA, a recently described indole-based SCRA. Clinical information and biological samples (blood, urine) were collected from patients...
AbstractThe potential for mirror neuron research to explain various aspects of social cognition has received considerable attention over the past two decades. Initially, mirror neuron research may seem in accordance with a phenomenological understanding of intersubjectivity, but the work of Dan Zahavi will be used to highlight significant incompatibilities between the two. Likewise, the...
Based on anthropological fieldwork on the revival of hallucinogen research as well as on the epistemic culture of neurophilosophy, this Common Knowledge guest column examines two very different philosophical engagements with psychedelic drugs. In Thomas Metzinger's evidence-based philosophy of mind, hallucinogens help to operationalize questions about the nature of consciousness. While this...
Abstract The contemporary academic study of religion has its roots in conceptual and theoretical structures developed in the early to mid-20th century. A particularly important example of such a structure is the concept of the “numinous” developed by the theologian and comparativist Rudolf Otto (1869–1937) in his work, The Idea of the Holy: An Inquiry into the Non-Rational Factor in the Idea of...
Only a small fraction of all the information reaching our senses can be the object of conscious report or voluntary action. Although some models propose that different attentional states (top-down amplification and vigilance) are necessary for conscious perception, few studies have explored how the brain activations associated with different attentional systems (such as top-down orienting and...
Klein & Barron’s (2016) (K & B’s) case for insect consciousness is a welcome development in an area that, in all of the science and philosophy of mind, is probably the most anthropocentric. In this commentary, we seek to strengthen K & B’s side of the argument by appealing not just to putative neural mechanisms but also to computational theory that supports it (section 1). We also offer some...
Understanding the nature of consciousness is one of the grand outstanding scientific challenges. The fundamental methodological problem is how phenomenal first person experience can be accounted for in a third person verifiable form, while the conceptual challenge is to both define its function and physical realization. The distributed adaptive control theory of consciousness (DACtoc) proposes...
Consciousness, and especially phenomenal consciousness (why it should feel like something), is a ‘hard’ problem in philosophy. It is not clear that it is amenable to a solution using neuroscience, but neuroscience does have many relevant and potential contributions to understanding phenomenal consciousness. It is argued that one route to action is the goal-directed route, with the goals set by...
