Hannan, Pólos and Carroll (2007) provided a new approach to basic logics of organization theory and sociology. They listed important obstacles to formal theory building in social sciences as (1) partiality of available knowledge (2) stochastic process (3) fuzziness of the boundary of social units. To overcome these defects they introduced fuzzy set theory and modal logics. From this approach we can expect the possibilities of (1) elaboration of study of social category formation (2) contribution to study of innovation (3) contribution to study of conflict (4) evaluation of generalizability of qualitative researches.
