Planarian Memory and Overstated Evidence

In this episode, we return to Iain McGilchrist as he spirals upwards from his binary hemispheric model into full cosmic spirituality. The rule is simple: everything McGilchrist likes is due to the subtle, nuanced, and deeply sophisticated right brain, while the left brain (pffft) is responsible for reductionism, modernity, and most of the problems in your life.

From this neuroscientific foundation, the theory expands with admirable ambition. Civilisations rise and fall depending on which hemisphere they inhabit. Ancient societies were properly attuned to the right brain, while the modern world has gone mechanical and spiritually bankrupt. The details are, of course, very complex, but the moral is clear.

Scientific evidence features occasionally, mostly in a decorative capacity or as parables of scientists being baffled by mystical forces. Hence, we learn that decapitated worms retain perfect memories, Nobel Prizes have been awarded for demonstrating a mystical direction powering evolution, and near-death experiences establish that memories form when the brain isn't functioning.

Alongside this hard science, McGilchrist also ventures into more spiritual realms, where we learn that artificial intelligence is likely to be channelling demons, schizophrenia might be caused by malign spiritual forces treating our brains as a luxury resort, and recently exorcised demons prefer to communicate via text message. No really...

Ultimately, what matters is that McGilchrist's bespoke theology, bespoke metaphysics, bespoke biological teleology, and bespoke panentheist philosophy are really very impressive. And if you don't find any of it compelling, well, we are sad to inform you that this itself proves you are stuck in the wrong mode of thinking and failing to recognise true profundity.

And if that doesn't work, then let's just say it was all a metaphor anyway!
