Time magazine has just published an intriguing article on the neural basis of consciousness. The article was written by Steven Pinker, a cognitive scientist known for his controversial views on language and cognition.
Here are several excerpts from the article…
On the brain being the basis for consciousness:
Scientists have exorcised the ghost from the machine not because they are mechanistic killjoys but because they have amassed evidence that every aspect of consciousness can be tied to the brain. Using functional MRI, cognitive neuroscientists can almost read people's thoughts from the blood flow in their brains.
On a new basis for morality emerging from neuroscience:
…the biology of consciousness offers a sounder basis for morality than the unprovable dogma of an immortal soul… 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.
On the evolutionary basis of self deceit:
Evolutionary biologist Robert Trivers has noted that people have a motive to sell themselves as beneficent, rational, competent agents. The best propagandist is the one who believes his own lies, ensuring that he can't leak his deceit through nervous twitches or self-contradictions. So the brain might have been shaped to keep compromising data away from the conscious processes that govern our interaction with other people.
