"Seeing and hearing what is not materially present and interpretations of those experiences that ascribe reality to the non-material became hallmark symptoms of psychosis. Such experiences were also hallmark characteristics of MRE (mystical religious experience), but the science of the day overlooked qualitative difference between these symptoms and characteristics. Some members of the scientific community at that time questioned the association of MRE with pathology and moved to address the issue by revising psychoanalytic theory. But there were also those who maintained that the association of religion with pathology was correct. And so the debate continued and continues in the twenty-first century."
