I am sometimes asked why, if the left hemisphere ‘take’ on the world is less insightful, it has come to dominate the way we think. And if this has happened not just once, but three times, as I believe, in Western history, how do I account for that fact? These are good questions. I think there are, again, several reasons why this characteristic entrenchment occurs, and indeed is likely to occur whenever a civilisation passes its peak. All of them, to some degree, illustrate the self-reinforcing, recursive nature of the left hemisphere’s world, a world subject to positive feedback.
