Howhy (Hohwy 2016, Hohwy 2017) argues there is a tension between the free energy principle and leading depictions of mind as embodied, enactive, and extended (so-called ‘EEE cognition’). The tension is traced to the importance, in free energy formulations, of a conception of mind and agency that depends upon the presence of a ‘Markov blanket’ Andrey Markov demarcating the agent from the...
N-Benzyl-substituted 2C class phenethylamines (NBOMes) are psychoactive designer drugs, with strong hallucinogenic and stimulant effects, even at low doses. The designer drug, 2-(4-bromo-2, 5-dimethoxyphenyl)-N-(2methoxybenzyl) ethanamine (25B-NBOMe) is considered to be one of the most potent agonists of the serotonin-2A (5HT2A) receptor. Recently, we reported the first lethal case of 25B-NBOMe...
The continuity hypothesis (1) posits that there is continuity, of some form, between waking and dreaming mentation. A recent body of work has provided convincing evidence for different aspects of continuity, for instance that some salient experiences from waking life seem to feature in dreams over others, with a particular role for emotional arousal as accompanying these experiences, both...
An exploratory study into the recent popular emergence of mindfulness (Achsamkeit). Contemporary mindfulness practices encompass secular self-help and therapeutic pedagogies such as MBSR, spiritual exploration and religious doctrine. This study is a qualitative analysis of the concept of mindfulness as it is entertained by its practitioners. The study was conducted according to a constructivist...
Background. The structure of consciousness has long been a cornerstone problem in the cognitive sciences. Recently it took on applied significance in the design of computer agents and mobile robots. This problem can thus be examined from perspectives of philosophy, neuropsychology, and computer modeling. objective. In the present paper, we address the problem of the computational model of...
Tiletamine is a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist chemically related to ketamine and phencyclidine. A common veterinary anesthetic drug, tiletamine is currently a Schedule III controlled substance in USA. This compound exerts sedative effects in humans and animals, also having an abuse potential, toxicity and dissociative hallucinogenic properties clinically....
In natural language, looks-talk is used in a variety of ways. I investigate three uses of 'looks' that have traditionally been distinguished - epistemic, comparative, and phenomenal 'looks' - and endorse and develop considerations in support of the view that these amount to polysemy. Focusing on the phenomenal use of 'looks', I then investigate connections between its semantics, the content of...
In recent debates on phenomenal consciousness, a distinction is sometimes made, after Levine (2001) and Kriegel (2009), between the "qualitative character" of an experience, i.e. the specific way it feels to the subject (e.g. blueish or sweetish or pleasant), and its "subjective character", i.e. the fact that there is anything at all that it feels like to her. I argue that much discussion of...
The mental realm seems different to the physical realm; the mental is thought to be dependent on, yet distinct from the physical. But how, exactly, are the two realms supposed to be different, and what, exactly, creates the seemingly insurmountable juxtaposition between the mental and the physical? This review identifies and discusses five marks of the mental, features that set...
Due to the illegality of psychedelic substances, and despite proven efficiency, people suffering from various psychiatric illnesses and disorders are unable to receive potentially life-changing psychedelic therapy. With the recent technological development of computer-mediated realities, designers and developers now have the opportunity to digitally recreate such treatments. Through practical...
