What happens when a worldly Israeli cognitive psychologist goes to the Amazon Basin where he ingests the famed psychotropic concoction Ayahuasca (the ‘vine of the dead’) again and again and again? Our intrepid philosophical psychologist is no longer a sprightly youth, maddened for adventure. He is instead an accomplished theoretician with widely published articles (several in this journal) and a noted book (Shanon, 1993) that speak the from the perspective of cognitive (or phenomenological, for Shanon) psychology against the (...) reductive tendency to view the mind’s activities as created by the the brain’s activities. Even before his Amazonian quest, he placed himself in the Gibsonian camp seeing the mind as dynamic intermediary between organism and environment and active participant in both. What did happen is this extraordinary book, a scientific analysis of his own visions and the education of both Shanon’s views and, perhaps, his soul. (shrink)
