This study which completes that published in the previous issue of the journal intends to describe the second aspect of British postmodernism as a trend of thought and no longer as an attempt to objectify the characteristics of a "postmodern" era (object of the first study). The author examines critically the attempt to establish within British geography ways of "thinking differently", i.e. breaking away from the dualist scheme of modem thought which is supposed to originate from the principle of domination. The description of this quest for "better" thinking takes into account the influence of the post-structuralist current, mainly imputable to French philosophers, in order to provide the essential needed means for understanding most postmodern texts.
