Abstract Psychedelic substances such as psilocybin, LSD, ayahuasca, DMT, or mescaline, when employed with knowledge and skill, can sometimes lead to profoundly meaningful and transformative subjective experiences. This chapter discusses how the predictive processing theory can further our understanding of these deeply meaningful spiritual psychedelic experience. It makes a more specific...

Psychedelic research has shown that the effects of serotonergic substances, such as psilocybin and LSD, are strongly influenced by the interaction of substance, set, and setting. Mystical-type experiences, often induced by psychedelics, are not solely driven by pharmacological mechanisms but emerge from a dynamic interplay between the psychological state (set), external environment (setting),...

The context for our paper comes from the neurophenomenology (NPh) research programme initiated by Francisco Varela at the end of the 1990s. Varela's working hypothesis was that, to be successful, a consciousness research programme must progress by relating first-person phenomenological accounts of the structure of experience and their third-person counterparts in neuroscience through "mutual...

The topic of my chapter will be Bud Craig's theory of "global emotional moments" (henceforth the GEMs theory) and the relationship of GEMs to the experience of time. I connect three ideas prominent in Craig's writings: interoception, emotion, and time. Craig held that each GEM has as its neural substrate a large-scale network with the anterior insula cortex (AIC) serving as its central...

The predictive processing theory refers to a family of theories that take the brain and body of an organism to implement a hierarchically organized predictive model of its environment that works in the service of prediction-error minimization. Several philosophers have wondered how belief-like states of prediction account for the conative role desire plays in motivating a person to act. A...

Our paper takes as its starting point the recent proposal, at the core of this special issue, to use the active inference framework (AIF) to computationally model what it is for a person to live a meaningful life. In broad brushstrokes, the AIF takes experiences of human flourishing to be the result of predictions and uncertainty estimations along many dimensions at multiple levels of...

Depersonalisation is a common dissociative experience characterised by distressing feelings of being detached or 'estranged' from one's self and body and/or the world. The COVID-19 pandemic forcing millions of people to socially distance themselves from others and to change their lifestyle habits. We have conducted an online study of 622 participants worldwide to investigate the relationship...

It is a near consensus among materialist philosophers of mind that consciousness must somehow be constituted by internal neural processes, even if we remain unsure quite how this works. Even friends of the extended mind theory have argued that when it comes to the material substrate of conscious experience, the boundary of skin and skull is likely to prove somehow to be privileged. Such...

There is substantial disagreement among philosophers of embodied cognitive science about the meaning of embodiment. In what follows, I describe three different views that can be found in the current literature. I show how this debate centers around the question of whether the science of embodied cognition can retain the computer theory of mind. One view, which I will label body functionalism,...

InHow the Mind Uses the BrainRalph Ellis and Natika Newton develop a novel embodied, enactive theory of consciousness, according to which consciousness has its basis in neural systems that prepare the system to perform actions of emotional significance to the organism. Consciousness emerges out of self-organising processes which function in such a way as to contribute to, and maintain, the...

AbstractOur perceptual experiences stretch across time to present us with movement, persistence and change. How is this possible given that perceptual experiences take place in the present that has no duration? In this paper I argue that this problem is one and the same as the problem of accounting for how our experiences occurring at different times can be phenomenally unified over time so...
