What I object to is, for example, a Skinnerian professing to understand other men as bundles of conditioned reflexes. Or Margaret Mead professing to understand Samoans by making them conform to her theory of culture, which she had in her head before she got to Samoa. You write a lot about the upside-downness of life. As the saying goes, we're probably not going to get out of this alive. Freud defines anxiety as the product of intrapsychical conflict.
Skinner defines it as a learned behavior.
In Zen philosophy, anxiety is an evil to be removed. Heidegger, on the other hand, defines anxiety as ontological, in that it tells us about our humanness. To say this is to say a good deal more than that illness is more interesting than health. The work of Gabriel Marcel has had a tremendous impact on your philosophy. If he can last another fifty years, he might make it.
