I completely disagree. This idea is based on the pathological model of allopathic medicine, i.e. "health is the absence of illness." Granted, that's the old common paradigm in Euro-American medicine.But in the past century or so, the model of health has become much more positive in orientation, more ecological, rather than pathological. This parallels the development of the psychological models of mental health, which began in pathology medicine, and eventually developed humanistic (Maslow) and transpersonal models (such as Grof, etc.)In traditional Chinese medicine, the paradigm for 200 years has been ecological, rather than pathological. So the idea that health is subtractive is really only a Western model anyway.
I'm inclined to agree with you, Art, especially so now that I have been studying tai chi (Chen style) for a bit.
