This paper is intended as a tribute to Andrzej Zawiślak, one of the precursors of systems approach to organization theory in Poland. More specifically, we highlight four recurring themes in his work: bridging academic-practitioner gap by studying systemic paradoxes, theorizing about organizations as complex human systems, reflection on the role of university in its social context, and scepticism towards rationality of social science. We believe that Zawiślak’s unique voice deserves to be heard and may serve as a fruitful starting point for theorizing about organizations.
