Episode notes

When it comes to practical tasks like building a table or fixing a window frame, mechanistic models and Newtonian physics work well. But just because we don't always need to take into account things like the roundness of the earth when building a garage, it doesn't mean that these principles no longer apply. Newtonian mechanics works well in certain situations, but when we look at the smaller or bigger scales, it no longer holds up. Quantum mechanics, on the other hand, is applicable everywhere. We can think of it as an overlay or approximation that works for most practical purposes. This understanding should extend beyond physics and apply to other fields like biology as well.

What would a post physicalist world look like?

So in this episode we’re going to evaluate the evidence presented by psychiatrist and author Dr. Iain McGilchrist, from his extensive analysis of split-brain studies, that support a broader understanding of the mind and reality. One that pushes beyond the traditional reductionist materialist worldview, to include the implicit, the context dependent and the consciousness dependent.

He’s just released an epic two part book to clarify all of this, ‘The matter with things: Our brains, our delusions and the unmaking of the world’ in which he asks how we should understand consciousness, space, time and matter, given the apparent over-emphasis on Left hemisphere interpretation of the world.

Iain is an associate Fellow of Green Templeton College, Oxford; he’s a Fellow of the Royal College of Psychiatrists; a Consultant Emeritus of the Bethlem and Maudsley Hospital, London; a former research Fellow in Neuroimaging at Johns Hopkins University Medical School, in Baltimore. And he now lives on the Isle of Skye, off the coast of North West Scotland.

He has published original research as well as original articles in papers and journals, including the British Journal of Psychiatry, Psychiatry & Psychology, The BMJ, The Lancet, The Wall Street Journal, The Sunday Telegraph and Sunday Times on topics in literature, medicine, psychiatry and philosophy. He has taken part in many radio and TV programmes and documentaries, including for the BBC, NPR, and ABC and also took part in a Canadian full-length feature film about his work called The Divided Brain.

This interview was recorded at the start of last year, so the new book is not covered in so much detail.
