The author suggests that development models influenced by the capitalistmodel of development overlooks nonmaterial dimensions ofdevelopment and underdevelopment. As a consequence of this, socialsciences, which are shaped by capitalist concerns also, do not examinethe negative consequences of colonization on underdeveloped societies.The problem is not just ideological it is also epistemological. Positivesocial science, according to the author an offshoot of capitalism, is alsounable to comprehend the most important consequence of colonization- other underdevelopment - the underdevelopment of the culturalsymbols, psychology, and language of the colonized societies. Theauthor advances a model that will help include an analysis of culturalsymbolicunderdevelopment in the study of development and underdevelopmentof societies.
