Thought leaders?

By
This is an interesting piece on a new book by Daniel Drezner:   https://www.nytimes.com/2017/04/11/opinion/this-age-of-wonkery.html

Sort of

There is a moving essay on the philosopher Daniel Dennett, in a recent New Yorker. It's by Joshua Rothman. This excerpt is near the end: "Then, late last year, my mother had a catastrophic stroke.

Neuroscience will explain our emotional responses as well as our problem solving abilities and our indefatigablecuriosity.    Purpose, however, may remain the domain of philosophy. Eagelman emphasises the unconscious functioning which determines most of our actions and decisions, and acknowledges Freud's insight that much of behaviour is a product of unseen mental processes. The concept of extended mind, whereby external stimuli and exchanges with other minds enables broader conceptualising capacity and creativity that an isolated human could not achieve, may in turn be extended by AI into some new more complex form of mind. One can choose to greet this news with optimism, as heralding a leap f...

Is consciousness just an illusion? Cognitive scientist Daniel Dennett believes the human brain might not be that special. Is the human brain really just a collection of complex machines? http://www.bbc.com/news/science-environment-39482345
