"Interdisciplinarians
often hope that some grand unifying theory will fall out of their efforts.
More often, it is found that multiple theories—and evidence from multiple
methods—are necessary. Integration occurs when the insights of each
particular theory and method are delineated, and it is shown how, in
combination, they yield a better explanation than any of them in isolation."
