This inquiry has emerged out of a search for a philosophy dealing with modern social problems, e.g. development and underdevelopment. By inquiring into G.H. Mead’s socio-philosophical anthropology, the author aims at establishing the basis on which philosophical explanations to given modern social problems may be grounded. In the course of this study, the author concentrates on two aspects: on the one hand, he intends to develop his hypothesis that Mead’s line of thought is to a great extent a philosophical anthropology, on the other hand, he has to develop his own terminology as part of the inquiry- e.g., the terms: supportivity and suppressivity of the self.
