Last month I participated in a symposium hosted by the Center for Theory & Research at Esalen, a retreat center in Big Sur, California. Fifteen men and women representing physics, psychology and other fields attempted to make sense of mystical and paranormal experiences, which are generally ignored by conventional, materialist science. The organizers invited me because of my criticism of hard-core materialism and interest in mysticism, but in a recent column I pushed back against ideas advanced at the meeting. Below other attendees push back against me. My fellow speaker Bjorn Ekeberg, whose response is below, took the photos of Esalen, including the one of me beside a stream (I'm the guy on the right). -- John HorganTo read more, click here.
