We are all aware of the placebo effect. This is often described as being the result of ‘sham’ or ‘fake’ treatments or pills with the fact being that the body would have ‘healed itself on its own’ or has its effect because the illness was ‘only in their mind.’
All of these attitudes represent a materialistic outlook, if not outright reductionism. This hard core atheistic outlook has been at the bottom of scientific development in all fields since the early 1900s, and this has certainly spilled over into medicine. This has sometimes been to the detriment, and even the embarrassment, of scientific progress as described in a book that is still one of my favorites, Dr. Jeffrey Schwartz’s The Mind and the Brain. The book charts the history of brain science up to the point where it was finally admitted that thought itself appeared to be able to shape the matter of the brain.
