Induced by intake of the psychedelic substances LSD, psilocybin, DMT and mescaline, psychedelic experiences have been extensively described by subjects as entailing a most unusual increase in the scope and quality of their consciousness. Accordingly, psychedelic experiences have been widely characterised as an “expansion of consciousness.” This article poses the following question, as yet unaddressed in contemporary philosophy and the tradition of phenomenology: to what exactly does “expansion of consciousness” refer as a general characterisation of psychedelic experiences, and what role (...) might attention play therein? On the basis of Aron Gurwitsch’s phenomenology of attention, the following thesis is presented: (a) “expansion of consciousness” refers to a particular restructuration of consciousness in psychedelic experiences. (b) This occurs by means of certain extreme transformations in direction, scope, mode and degree of attention. In order to explicate this thesis, the characteristic features of psychedelic experiences that pertain to expansion of consciousness and attention are first systematically identified from a survey of subject reports. Second, it is demonstrated that the few previous attempts to understand expansion of consciousness in terms of attention as a filter/reducing-valve, spotlight or zoom-lens each fail to explain how consciousness is structured in psychedelic experiences. Third, it is argued that psychedelic expansion of consciousness is a general restructuration of consciousness by means of extreme attentional transformations. In conclusion, brief consideration is given to the question of whether psychedelic expansion of consciousness can have epistemic and ethical value for life. (shrink)

Merleau-Ponty and Contemporary Philosophy is an ambitious collected volume of fourteen chapters, accompanied by an epilogue by Jean-Luc Nancy, in which current Merleau-Ponty scholars together aim to demonstrate the urgent relevance of Merleau-Ponty to contemporary philosophy across a range of fields including ontology, epistemology, anthropology, embodiment, animality, politics, language, aesthetics, and art. Divided into four thematic sections, namely, “Legacies”, “Mind and Nature”, “Politics, Power, and Institution” and “Art and Aesthetics”, this collected volume provides a rich resource for Merleau-Ponty scholars who (...) are interested in novel applications and understudied aspects of his thought. It also opens up Merleau-Ponty’s oeuvre to the general reader, presenting many possible entry-ways into the diversity of his work. In my review of Merleau-Ponty and Contemporary Philosophy, I suggest that each of its thematic sections could have been the subject of a separate volume themselves, and that the volume would then perhaps have not suffered from a number of poorly developed lines of argumentation. But I consider that the inclusion of all these thematically diverse sections in a single volume nonetheless presents a forceful display of the wide-ranging relevance of Merleau-Ponty’s work to contemporary philosophy.
