His academic journey took him from the University of Zagreb to a stint in the Soviet Union, where he witnessed the repression of philosophical thought under Stalin—a formative experience that steeled his resolve for independent thinking. He earned his PhD in 1956 and subsequently taught logic and the theory of philosophy at the University of Zagreb until his retirement. His intellectual courage, however, came at a price. His support for student protests in 1968 led to his expulsion from the Party. Yet, his legacy endures through his writings, and in 2001, a collection of articles in his honor, The Reality and the Criticism , was published in Zagreb.

In formal logic, a contradiction terminates the proof (explosion principle). In Petrović’s dialectical logic, a contradiction is the engine of thought. The new PDF contains a stunning diagram (missing from old versions) showing how contradiction is the "motor of the concept."
