Neuroscientist: Brain Surgery Can Create “Two Conscious Entities”

Christof’s idea that split brain patients have split consciousness doesn’t really make sense and doesn’t correspond to the evidence. Consciousness is metaphysically simple — that is, my thoughts and sense of self can’t be split with a knife like the brain or a material thing can be split. What would it mean to say that I have “split” consciousness? Instead of Mike, there would be Mike and Joe, which wouldn’t be “split,” it would just be two people.

A category error

‘Split consciousness’ is an oxymoron, a category error. Consciousness is not the kind of thing that can be split, and there’s no evidence that one person can ever become two people. It’s science fiction, not science.
