“By the formal, rational, rules of science, which have worked so well in understanding the physical world, human beings occasionally have experienced and show certain behaviours that cannot be reduced to materialistic explanations and that look like fundamental aspects of a spiritual nature.”
Dr. Charles T. Tart, The End of Materialism
Dr. Charles T. Tart is internationally known for his more than 50 years of research on the nature of consciousness, altered states of consciousness (ASCs) and parapsychology, and is one of the founders of the field of Transpersonal (spiritual) Psychology. His and other scientists’ work convinced him that there is a real and vitally important sense in which we are spiritual beings, but the too dominant, scientistic, materialist philosophy of our times, “masquerading as genuine science, dogmatically denies any possible reality to the spiritual.” He says this hurts people, it pressures them to reject vital aspects of their being.
