“The idea of freedom and the idea of progress are connected in the sense that the world cannot escape from its past if it is not free to abandon the present. Utopian social engineering rests on the assumption that we can design a perfect state. Open society accepts imperfection and incremental reform.”

Commentary
Popper defends 'open society'—pluralist, democratic, fallible—against 'closed society'—totalist, utopian, claiming perfect knowledge. Utopian engineers (Plato, Hegel, Marx) assume they can blueprint the perfect state. This inevitably leads to authoritarianism because implementation requires suppressing dissent.
Against this, Popper advocates 'piecemeal social engineering': incremental reform, testing, and adjustment. This prefigures falsificationism applied to politics: try small reforms, assess results, adjust. This is epistemically modest but practically robust. It influenced political theory, development economics, and adaptive governance.
