Working with different cultural paradigms can be useful in highlighting differing aspects of the same problem. If Foucault had included Spain in his study of the history of the Insane Asylum then his results would have been very different because Spain has some of the oldest treatments of mental illness and a very different perspective from both France and England. Jay Garfield's article on the bodhidharma's travel East shows how a problem can arise in one culture but their paradigm doesn't allow for an answer while another cultural paradigm can produce an answer to a problem raised that their cultural paradigm would not raise themselves. I understand that this indirectly related to your question, though it does show that your question has a philosophical basis.
