What Is the ‘Unitive Mystical Experience’ Triggered by Psychedelic Medicines an Experience of? An Exploration of Aldous Huxley’s Viewpoint in Light of Current Data

Abstract

A large body of research in the field of psychology currently points to a variety of therapeutic outcomes derived from psychedelically occasioned mystical experience. Moreover, additional research suggests that such benefits to mental and emotional well-being may depend directly upon the subjective mystical experience itself, rather than upon the substances that triggered it; for instance, research at Johns Hopkins indicates that higher scores on the MEQ30 or MEQ43 might be key predictors of larger therapeutic outcomes. However, the ‘elephant in the room’ often overlooked in psychological studies is this: What exactly is it about the content of the subjective experience that triggers such significant outcomes or, of deep interest philosophically speaking, what might the mystical experience be an experience of? Could it be that such experiences have a viable ontological referent instead of their being wholly subjective and if so, how might Aldous Huxley’s theory in this regard be weighed in light of current data? The essay includes close discussion of the debate regarding the nature of mystical experiences between Robin Carhart-Harris’ REBUS model (the experiences are wholly subjective, with no ontological referent) vs. Edward Kelly’s ROSTA model (contending an ontological referent need not contradict the science). The essay’s thesis is that Huxley’s viewpoint includes plausible and perhaps valuable insights that may help explain why and how that encounter has such profound therapeutic value.
