This study is a theoretical exploration of Michel de Certeau's theories. The emphasis is placed on his notion of "tactics". Some of the issues to be addressed are: the tension existent in every social organization in terms of controlled "places" and dynamic "spaces", and the theorization of the figure of the "addressee" which, as this study argues, is a central and complementary step to de Certeau's ideas. The conclusion suggests an alternative reading of the notion of "tactics" supported by concepts developed by rhetorical theory.
