The mind-body problem Down Under

Mind. Brain. Are they the same thing, or is the mind something special? The conundrum has perplexed us for centuries. Descartes split the two - into a spiritual, soul-like mind and fleshly, material brain. But in 1956 a group of 'renegade' Oxford graduates Down Under, now international stars in philosophy, launched a challenge. Consciousness and the brain were united, and any talk of mental spooks and ghosts in the machine was out...almost. Now in their 80s, David Armstrong and Jack Smart and others reminisce on taking Descartes to task.
