At the heart of Petrović’s project is a critical examination of traditional, or "bourgeois," logic.

Comprehensive frameworks can anesthetize doubt; they can transform living questions into settled answers. He cautions against this appetite, arguing that philosophy’s task is not to produce one final architecture but to keep alive the questions that unsettle power and open paths to rearrangement.
