Toward an ecological view: Complex systems, health, and disease|
By Ted Schettler, M.D., MPH.
Complex relationships among genetic, biologic, toxicologic, nutritional, geologic, economic, political, social, cultural, and historical phenomena are major determinants of health or disease. The dominant scientific approach to understanding this complexity involves taking it apart in order to examine more manageable pieces. That approach emphasizes the role of parts and de-emphasizes relationships. Then, in an attempt to understand some larger whole, scientists often construct models built of selected individual variables from the ground up, referring to "independent" variables that combine to determine the "dependent" outcome of interest.
