Medical research has become more laboratory oriented in the last fifty years. To be sure, this shift has produced some impressive results. But at the same time, human biology is not exclusively mechanical, and there are limits to what the laboratory can accurately study. The laboratory study of infectious diseases has been magnificent - it is very straightforward. But its very success has deflected attention from the influence of emotions. As a result, medical research has failed abysmally in many areas. The evidence is everywhere you look. Pain problems have become epidemic. Gastrointestinal, dermatologic, and allergic conditions are increasingly widespread, all because laboratory identification of the physics and chemistry of these conditions does not, contrary to popular medical belief, identify their cause.
