There’s a wonderful piece by Steven Pinker in the latest Time, entitled The Mystery of Consciousness. After reviewing the state of research on consciousness and the brain, he considers Chalmers’ notorious “Hard question”, nods at Dan Dennett’s rebuttal, (appropriately) dismisses Searle’s quantum nonsense, and (provisionally) accepts Colin McGinn‘s “cognitive closure” view. He concludes optimistically:
As every student in Philosophy 101 learns, nothing can force me to believe that anyone except me is conscious. This power to deny that other people have feelings is not just an academic exercise but an all-too-common vice, as we see in the long history of human cruelty. Yet once we realize that our own consciousness is a product of our brains and that other people have brains like ours, a denial of other people’s sentience becomes ludicrous. “Hath not a Jew eyes?” asked Shylock. Today the question is more pointed: Hath not a Jew — or an Arab, or an African, or a baby, or a dog — a cerebral cortex and a thalamus? The undeniable fact that we are all made of the same neural flesh makes it impossible to deny our common capacity to suffer….
Think, too, about why we sometimes remind ourselves that “life is short.” It is an impetus to extend a gesture of affection to a loved one, to bury the hatchet in a pointless dispute, to use time productively rather than squander it. I would argue that nothing gives life more purpose than the realization that every moment of consciousness is a precious and fragile gift.
Indeed it is. Enjoy.
