ABSTRACT
George Brown has made several great contributions to his chosen field. Although they can be separated into theoretical and methodological aspects, they are in fact linked: the methodological innovations, which have had a major impact on social psychiatry, are inevitably driven by theory. The methodological developments could be regarded merely as an energetic devotion to the creation of many useful research instruments and techniques, but the most striking thing about them is that they bridge an ancient gap between the natural and social sciences. In doing so, they call in question the reality of this traditional division.
