Of the so-called global theories the one initially stated and defined by Bertalanffy in 1947 under the title of "general systems theory" has taken hold... Since then he has refined, modified and applied his concepts, established a society for general systems theory and published a General Systems Yearbook. Many social scientists but only a handful of psychiatrists studied, understood or applied systems theory. Suddenly, under the leadership of Dr. William Gray of Boston, a threshold was reached so that at the 122nd annual meeting of the American Psychiatric Association in 1966 two sessions were held at which this theory was discussed and regular meetings for psychiatrists were ensured for future participation in and development of this "Unified Theory of Human Behavior." If there be a third revolution , it is in the development of a general theory. (en) |
