In the above video, Iain McGilchrist argues that modern society promotes the left side of our brains at the expense of the right (and superior) hemisphere. A snippet:
Both hemispheres are necessary, McGilchrist says … “but one is more fundamentally important than the other, and sees more than the other, even though there are some things that it must not get involved with, if it is to maintain its broader, more complete–in essence more truthful–vision. This is the right hemisphere, which, as I demonstrate from the neuropsychological literature, literally sees more, and grounds the understanding of the left hemisphere–an understanding which must ultimately be re-integreted with the right hemisphere, if it is not to lead to error. The left hemisphere is extraordinarily valuable as an intermediate, but not as a final authority.”
