I have started to read the book Food of the Gods by Terence McKenna and it really has been an enjoyable and enlightening read. I have only gotten through about 1/3 of the book, but he does a good job in explaining the evolution of mankind and how it may have come about with the help of entheogens. I have read a lot of other works on the subject of religion and the use of psychoactive substances in order to understand the evolution or religion, but I have always wondered where they got their source of ideas. It seems that McKenna may have been that source.
Terence McKenna is a well educated and well traveled man, and you can see this in his writings. He could be described as an anthropologist even though he only had a Bachelor of Science degree in Ecology and Conservation. The one great thing is that McKenna is that in his writings he doesnt come off as an aggressive person. He shows a way that's possible and kind of lets you decide. He intrigues you with interesting stories and situations and lets you find your way. I have heard a few of hes recorded speeches, but never really liked the guy because of how people seemed to follow him (cult style) but I do enjoy his writing and agree that this is one possible explanation into our relationship of plants.
