The article reconstructs and analyzes the various stages of the thought of Zygmunt Bauman. From the beginning, through the maturity, to the last period, the article defines the central nodes of the Baumanian sociological constellation, introducing their interdisciplinarity and cognitive tension. This theoretical reconstruction is a "mission impossibile" very similar to that done by the Polish sociologist in his analysis of modernity.
Keywords: Bauman; sociological theory; interdisciplinarity; modernity; post-modernity.
