I understand what you're getting at Bob, but I think you are still defining science in a limiting way. Science does not just describe and possibly validate human experience, it can also explain it, which is by far the most valuable aspect to the tool. For example, by using the scientific method to study the effects of various substances on the human body at a cellular level, we now understand a great deal about precisely how drugs have the effects they do. With this knowledge, we can look at the chemical structure of a substance and have a pretty good idea of what it's going to do to a person. Furthermore, we can look for/synthesize chemical structures that will achieve the sought after effects of drugs without unwanted side effects.
A system for this sort of analysis/synthesis of knowledge is precisely what is lacking in a system such as TCM, and will continue to be lacking until the tool of the scientific method is applied to the study of TCM.
