János Kornai rejected the relevance of Walrasian equilibrium and considered only disequilibrium states to be compatible with reality in his Anti-Equilibrium. His research was guided by the belief that reality and theory should form an integral unit. Neoclassical economists did not accept his anti-equilibrium theory, which motivated Kornai to relentlessly provide additional evidences. The article follows this exciting and noble struggle from a new perspective in the context of scientific theory.
