Seminal work on human psychological evolution
1 of 1 found this helpful In many respects, this is an extended research paper on the origins of humanity. It particularly explores the evolution of human psychological capacity and its connection to the use of psychedelic plants. As with most evolutionary psychology, McKenna's project is speculative. It is, however, also thoroughly researched. So, while McKenna's theory is but one contender in the scientific conversation on the origins of humanity, it should not be considered fringe or "new age." McKenna adheres to the scientific paradigm while expanding the conversation into admittedly controversial territory. This is essential reading for anyone who is serious about exploring the nature and origins of human consciousness. The book is perhaps best, however, where McKenna steps out of the scientist's role and into that of the shaman. He is willing to build a prescriptive philosophy around his theory and advocate for the continuation of a human relationship with psychedelic plants. When one acknowledges widespread strife in the present-day human experience, and also the brink of global environmental disaster we find ourselves facing today, a radical perspective may be just what we (and future humans) need.
