Popper had just published The Open Society and Its Enemies in 1945, attacking Plato, Hegel, and Marx; he was already closely allied with Hayek, who would conspire to bring him to the LSE. Popper notoriously had argued that a regime of open criticism and dispute was the only correct path to political progress; this dovetailed with his influential characterization of science as an ongoing process of conjecture and refutation.
