A new generation of celebrity gurus has arrived. The clinical psychologist Jordan Peterson, the historian Yuval Noah Harari and the comedian Russell Brand are three prominent examples. They command podcast downloads that run into six figures, their books are at the top of amazon rankings, they stir up controversy. In this Science Set Free podcast, Rupert Sheldrake and Mark Vernon ask what their appeal means, what can be made of their various messages, and what this might mean for non-materialist worldviews. Rupert has himself talked with Russell Brand on Under The Skin and he reflects on the experience. Their discussion also ranges over why Jordan Peterson provokes conflict, why Harari’s bleak story of humanity sells, and why Russell Brand is today one of the most visible promoters of spiritual reality.
