Closing the session

Christopher Timmermann (Imperial’s DMT Research Group) is one of the world's leading researchers on DMT and 5-MeO-DMT. These are amongst the most powerful psychedelics we know. DMT is famous for catapulting people into hyper-real alternate worlds populated by seemingly autonomous beings.

5-MeO-DMT evokes experiences of “pure consciousness” featuring a complete loss of ego, self and time. 

For anyone interested in the nature of reality and mind, these experiences deserve consideration. 

Christopher presents his work on human neuroimaging studies on DMT, mapping what happens in the brain in these "more real than real” spaces. His latest work includes a study with a meditation lama comparing advanced meditation and psychedelic states.

He discusses with Bernardo his influential research showing that psychedelic experiences can shift people’s most basic metaphysical beliefs away from hard physicalism.

In turn, Bernardo presents his philosophy and how he interprets psychedelic experiences such as the ones Christopher researches.

We're also delighted to offer you a 20% discount to Unlocking The Psychedelic Mind, a 10 week course starting Jan 2026 with Dr. Chris Timmermann. This immersive online course dives into the therapeutic effects of psychedelics, the intersection between psychedelics and meditation, and their role in unlocking creativity and flow states.

Bernardo Kastrup

Analytic idealism

Bernardo Kastrup is the Executive Director of Essentia Foundation and Founder/CEO at AI systems company Euclyd BV. His work has set off the modern renaissance of metaphysical idealism. He has a Ph.D. in philosophy (ontology, philosophy of mind) and another in computer engineering (reconfigurable computing, artificial intelligence).

As a scientist, he has worked for the European Organization for Nuclear Research (CERN) and the Philips Research Laboratories (where the ‘Casimir Effect’ of Quantum Field Theory was discovered). He has also been creatively active in the high-tech industry for almost 30 years, having founded parallel processor company Silicon Hive (acquired by Intel in 2011) and worked as a technology strategist for the geopolitically significant company ASML. Most recently, he has founded AI company Euclyd BV.

Formulated in detail in many academic papers and books, his ideas have been featured in Scientific American, the magazine of The Institute of Art and Ideas, the Blog of the American Philosophical Association and Big Think, among others. His most defining book is Analytic Idealism in a Nutshell: A straightforward summary of the 21st-century’s only plausible metaphysics.
