"William Newell’s theory of interdisciplinary studies is a timely proposal since complexity is a keyword in contemporary descriptions of interdisciplinarity. Like any other theory, it is subject to a series of questions: (1) Is the theory generalizable, and is it reductive? (2) What relationship does it have to prior theories? (3) Does the theory drive practice, or vice versa? and
(4) Is it fruitful? A weighing of these and related questions indicates that complex systems theory has heuristic value for conceptualizing interdisciplinary tasks and affirms crucial elements in the integrative process. However, the technical restrictions cannot account for all phenomena that constitute interdisciplinarity, and the relationship to other theories needs to be assessed."
