Ralph and myself (Zach Leary) sat down at the MAPS Psychedelic Science '17 conference in Oakland, CA on April 23rd to embark on a wide reaching conversation that focussed on the early days of his research at Harvard, the culture of the 60's and how much has changed in the last 50 years. Of course, we also talked about the time he spent with Timothy Leary and Richard Alpert, the nature of consciousness itself and a new way of thinking about "ecology" as a concept. His new book "Ecology of Consciousness: The Alchemy of Personal, Collective, and Planetary Transformation" is out now wherever books are sold. Ralph is truly one of the great inspirational elder statements of the modern psychedelic movement and I hope you enjoyed this as much as I did.
