Video Description

Sam Harris, Roger Penrose, and Sophie Scott discuss consciousness, altered states, split brain patients, and the illusion of the Self. If you really look for it, can you ever find the Self? With a free trial, you can watch the full debate NOW at https://iai.tv/video/the-divided-self-sam-harris-roger-penrose?utm_source=YouTube&utm_medium=description Many have sought to divide the self into separate parts. From Aristotle's distinction between the rational and irrational self to Freud's separation of the conscious and unconscious mind, from Kahneman's fast and slow self to McGilchrist's selves of the left and right brain. But critics argue it makes no sense to see the self as divided. From Descartes to Sartre, many philosophers have concluded that to be conscious is to be conscious of something and there can be no further self hiding within consciousness. After all, if there are two aspects of the self does it not require a third to oversee or combine them? Meanwhile, neuroscience has been unable to identify a self at all let alone multiple selves. Should we give up the idea of distinct selves as simply incoherent? Should we conclude that a single self is necessary to account for conscious experience and to enable responsibility for action? Or are multiple selves a better way to explain the wildly divergent thoughts and contradictory behaviours that we can sometimes exhibit? #consciousness #philosophy #neuroscience #psychology #science #buddhism Neuroscientist and philosopher Sam Harris, Nobel Prize winner Roger Penrose, and director of the Institute of Cognitive Neuroscience Sophie Scott discuss whether the self is divided.
