Much that was hastily ejected centuries ago now queues patiently at the back door. Much of the metaphysical element was lost from medicine and this allowed its total domination by materialism. This was a path of dis-integration and the separation of medicine from its spiritual homeland. The path back home for medicine seems to be a purpose for the holistic therapies. They seem doomed to loom larger in importance.
All future roads lead back to the ancient systems and back into greater holism.
In many senses, the disintegrative force of reductionism has run its course. Integration seems a likely way ahead.
