Gary Clark: 'Jung Was 100 Years Ahead!' How Psychedelics Are Proving the Collective Unconscious is Real
Archetypes As Ancient Brain Systems
- Jung's archetypes likely map onto evolutionarily ancient, subcortical emotion systems.
- These primary-process systems predate cortical consciousness and surface in dreams and ritual.
Psychedelics Reveal Deeper Mind Layers
- Psychedelics loosen the cortical 'ego' networks and allow older brain systems to enter awareness.
- This neural collapse explains numinous experiences, dreams, and therapeutic recalibration.
Use Rigorous Protocols For Psychedelic Research
- Study psychedelics in controlled clinical settings with preparation and guidance.
- Use standardized doses, fMRI, and structured reporting to link subjective reports with brain changes.


































"Jung was essentially an evolutionary theorist". These are the words of Gary Clark, a Visiting Research Fellow in the School of Medical Sciences at the University of Adelaide in Australia, who has written a book on the intersection of Jungian Analytical Psychology and evolutionary neuroscience.

In this conversation, I sit down with Gary to explore the intersection of Jungian psychology and evolutionary neuroscience, examining how recent psychedelic research provides empirical validation for Jung's theories about the collective unconscious and archetypes. We discuss how modern neuroscience, particularly studies of primary and secondary consciousness systems, maps onto Jung's framework of ego consciousness versus deeper archetypal layers. The conversation covers the revolutionary potential of psychedelic research for studying previously inaccessible aspects of consciousness and Jung's prescient evolutionary approach to depth psychology.
