Tony Johnson: Scientism is the faith that science already understands everything. There are two kinds of faith: faith in things which cannot be proven, and faith in things which have been disproven. Your faith lies in the latter. Many times science has reversed itself. Margarine good for your heart, oops, it’s bad for your heart. Eric’s faith is in a procedure which is not fully understood. Sometimes it works, and sometimes doing the exact same thing (or so we think) it doesn’t work. That said, it sometimes works and it’s relatively harmless. A substitute for medical attention? No, but it can be a precursor given that it calms a patient and reduces white coat anxiety.
