Contemporary developments in western health-care (Allopathy), though moving towards holism, lack an integrative conceptual foundation. This work offers a conceptual foundation for an interpretation of human-being that is holistic (conceptualizes mind/matter) and is compatible with western medical concepts. I offer a philosophical speculation portraying the holism of processes of health, illness, and healing. This speculation begins with an interpretation of human-being as a psycho-physical process of assimilation; in the personal locus of this process the mind-matter dichotomy dissolves. There are four sections in this work: (1) The statement of the philosophical speculation; this is the "Theory of Analogous Functioning" (T.A.F.). (2) This theory is set in a framework of analysis of systems of medicine as interpretations of the structural-functional nature of human-being. This analysis results in: (1) systems of medicine appearing as "meaning systems", that is, "lenses" through which physicians view patients; and, (2) clarification of the "comprehensive organic rationale" (COR) underlying holistic systems (Chinese, Asian Indian, T.A.F.). This analysis reveals the conceptual "form" common to these interpretations of the holistic nature of human-being. That is, a "generic form" of holism is revealed. (3) Discussion of the relation of four fields of thought to the holistic interpretation of human-being presented in T.A.F., in four appendices. Appendix A. Process philosophy. A.N. Whitehead and Hans Jonas. Discussion of the concepts "prehension" and "transcendence." Appendix B. Hermeneutics. Discussions of contemporary works supportive of process theories: R.C. Neville's theory of "value" in Nature; Richard Rorty, issues of western concepts of knowledge ("Mirroring of Nature"); and Mark Johnson's non-objectivist theory of meaning. Appendix C. Medical anthropology. A discussion of the relation of belief to healing. Appendix D. Systems of medicine. Five systems are discussed as "meaning systems": Allopathy, Acupuncture, Ayurveda, Homeopathy, and Tibetan Medicine. (4) A discussion of cancer from the process perspective of T.A.F. This perspective suggests some cancers may be the consequence of disrupted processes of personal psycho-physical assimilation. In summary, T.A.F. defines human-being as a locus of psycho-physical assimilation, and is the basis for a holistic system of diagnosis and therapy compatible with western medical perspectives. This theory rests upon a conceptual foundation identical in form to the conceptual foundations of traditional Chinese and Indian systems of health-care. Thus, T.A.F. rests upon philosophical resolution of the mind-matter dichotomy, and offers a method of analysis from which a system of holistic diagnosis and therapy can be developed.
