Out Of Our Heads: Why You Are Not Your Brain by Alva Noë
Kurt Keefner tells you why you can’t be only your brain.
It always goes back to René Descartes. Descartes said that each of us consists of a non-physical mind inside a physical body. The mind, which in his view is the person, is in a different dimension to the body, as it does not exist in physical space (he would say, ‘mind is not extended’, although it connects with the brain in a definite location, the pineal gland). This aspect of Descartes’ view was jettisoned, but the core template of ‘little true self in big extraneous self’ was retained. However, instead of a non-physical mind, the inner, true self came to be regarded as the brain.
