A few people have queried whether the book I mentioned last week, The Evolutionary Mind (Amazon US and UK), is related to the “Trialogue” lecture series from Rupert Sheldrake, Terence McKenna and Ralph Abraham. The short answer is yes, and I should have pointed out that you can listen to this series absolutely free on Rupert Sheldrake’s website (along with a host of other fascinating lectures by Sheldrake). Real Player is required for most files.
