Metaphysics and Psychedelic Research

Talk date & time :

Friday 15:00-16:00


It will be argued that psychedelic-induced metaphysical experiences should be evaluated and integrated with recourse to metaphysics. Psychology and Psychiatry alone are inadequate to do so, as the varieties, and determination of the veridicality, of such experiences are not in their professional ambit. There is a wide range of psychedelic experiences, some of which can be classified as ‘metaphysical experience’. Consider, for instance, reported psychedelic experiences of timelessness, extended specious present, nature-connectedness, sentient otherness, extra- qualia sensibility, pure consciousness, etc. How are patients undergoing psychedelic therapy to make sense of such experiences so to integrate them into their lives? Rather than immediately dismissing them as necessarily delusions under the assumption of the metaphysical position of Physicalism alone – which is the basis of the ‘Comforting Delusion Objection’ to psychedelic therapy, and partly of the debate between ‘Contextualism and Perennialism’ – the discipline of metaphysics can better situate, explain and thus make sense of such extraordinary experiences to patients. It is conjectured that opening the patient to such metaphysical possibilities, following their experience, may extend the long-term benefits of psychedelic therapy as the patient may be less inclined to immediately dismiss an experience as delusional but more inclined to consider its possible grander significance. Beyond the traditional, false dichotomy of Physicalism/Dualism the discipline of Metaphysics presents varieties of Neutral Monism, Idealism, Panpsychism, Pan(en)theism, transcendentalism, etc., and associated therewith are different conceptions of time, nature- connectedness, consciousness, etc. It would be negligent to omit metaphysics from therapy that can occasion metaphysical experience.
