Twenty-first Century Brains
May 10, 2017
Though the 1990s were dubbed, the “decade of the brain” by scientists, there is something extraordinary occurring in the present decade that shouldn’t be ignored. Some of the brain research done during the end of the last century has spurred scientists and humanists to think differently about many things. The leaders in this renaissance of brain science and philosophy are writing books and articles for a lay audience–so many it’s been hard to keep up with them (though I have tried my best to do so).
My favorite “brainiacs” in the field are Antonio Damasio, Daniel Dennett, Eric Kandel, Paul Bloom and Merlin Donald. Each has written several books pressing society to more seriously consider new discoveries about the brain and its workings in our daily lives.
Damasio famously debunked Cartesian dualism (the mind-body problem) and unveiled the complex palette of emotions built into our nervous system. Dennett “explained” consciousness from both a philosophical and scientific perspective. Kandel gave us a masterpiece about the neuroscience of “memory” and subsequent books about art. Bloom spent his career studying how babies develop an inner sense of “moral” judgment. Donald gave us a theory of how the human “mind” evolved from the brains of early hominids over hundreds of thousands of years.
I have just finished a new book by Dennett, entitled From Bacteria to Bach and Back. Dan has never been one to overlook a pun when it serves his purpose as a writer. In it he attempts to synthesize much of the brain science and evolutionary theory that have informed his philosophy. Reviewers have praised the book for its broad sweep and lively writing, and I found it fascinating, though too clever by half.
Two of the big ideas in BBB are intended to shake things up: the concept of “memetics” as a science, and the radical idea that consciousness is “an evolved user interface” with the outside world. For anyone interested in philosophy or cultural history, these perspectives are fascinating.
The news here is that brain scientists are pressing society to take note of the major discoveries that will change the way we live in the very near future–through advances in medicine, pharmacology, behavioral science, psychotherapy and other fields–transforming the world for the better. Robert Sapolsky’s Behave is a case in point–a Stanford professor on the talk show circuit explaining the evolution of the human brain to TV viewers. A generation of brilliant researchers is breaking out of their laboratories and taking to the streets. Watch out, they’re dangerous, like wild baboons.
