“The word entheogen was coined to denote psychedelic chemicals and botanicals that engender the experience of god within. drawing on william james, charles tart, and ken wilber, the authors claim that a complete study of religion must include entheogens, and they propose topics leading toward an entheogen research agenda: (a) the spititual nature of the human mind, (b) the dispute over the authenticity of entheogen-assisted religious experiences, (c) pastoral counseling, (d) experimental mysticism, (e) entheogenic origins of religion, and (f) policy issues in freedom of conscience and freedom of religion. the authors conclude with seven recommendations to churches, religious orders, seminaries, and scholarly and scientific professional groups for actions they can take to promote entheogenic research.”
