But bad results.
The collectivists … have the zest for progress, the sympathy for the poor, the burning sense of wrong, the impulse for great deeds, which have been lacking in latter-day liberalism. But their science is founded on a profound misunderstanding …, and their actions, therefore, are deeply destructive and reactionary. So men’s hearts are torn, their minds divided, they are offered impossible choices. WALTER LIPPMANN.

Popper, like Lippman, gives Marx credit for good intentions, but attributes his failures to the fundamental error of his analysis. Like Plato and Hegel, Marx was a "historicist" who was convinced that history was deterministic and headed inevitably in the direction that he predicted. Marx, says Popper, was influenced by the determinism of Laplace and the physicists of his time, a notion neither justified by theory and law or even by the subsequent evolution of physics.
