The hard problem

Why can’t the world’s greatest minds solve the mystery of consciousness? First-rate review of competing ideas about what makes human beings more than complex robots. “It would be poetic – albeit deeply frustrating – were it ultimately to prove that the one thing the human mind is incapable of comprehending is itself. An answer must be out there somewhere. And finding it matters: indeed, one could argue that nothing else could ever matter more – since anything at all that matters, in life, only does so as a consequence of its impact on conscious brains. Yet there’s no reason to assume that our brains will be adequate vessels for the voyage towards that answer. Nor that, were we to stumble on a solution to the Hard Problem, on some distant shore where neuroscience meets philosophy, we would even recognise that we’d found it.” Highly recommended. Clear, thorough.

Two heads: Paul and Patricia Churchland

Larissa MacFarquhar’s profile of Paul and Patricia Churchland’s “marriage devoted to the mind-body problem.” “One afternoon recently, Paul says, he was home making dinner when Pat burst in the door, having come straight from a frustrating faculty meeting. ‘She said, “Paul, don’t speak to me, my serotonin levels have hit bottom, my brain is awash in glucocorticoids, my blood vessels are full of adrenaline, and if it weren’t for my endogenous opiates I’d have driven the car into a tree on the way home. My dopamine levels need lifting. Pour me a Chardonnay, and I’ll be down in a minute.” ’ ”
