This past weekend I listened to the TED radio hour (you might be more familiar with www.ted.com ) that discussed creativity from the point of view of a scientist, an educator (this was the only name I remember--Sir Keith Robinson), and performance artists. I will go to the TED website and look into it further.
The main premise was that artist's brains, during the creative process, light up in certain areas like a pinball machine, but their frontal lobe actually almost disconnects at the same time. Seems we artists need to get out of our own way so that the process can continue. Creativity works better when we subdue our subconscious and quit worrying about failure and/or what anyone else may think of our efforts.
We all need art. Robinson said that education is now being operated the way a Fortune 500 corporation would handle it. Corporations no longer hire people with only one degree they want more paperwork to flap about. He also said that the more education leans that way, the less innovative the corporations will be because they will have eliminated any creativity that doesn't fit the "bottom line".
Boy, I hope not.
