 One significant evidence of the transition of Hook’s thought on economic issues is available in his early encounter with the writings of Friedrich von Hayek, the economist of the Austrian school which had developed the thesis that democratic socialism was incoherent from both economic and political perspectives. Hook wrote a review of Hayek’s Road to Serfdom which confirms the shift from his earlier view on Marxism and socialism. Far from asserting his earlier thesis that the achievement of political democracy require socialism or, at any rate, a greater degree of economic democracy in the form of lessened concentration of economic power in the capitalist class, Hook advanced the criticism that Hayek’s thesis paralleled in a significant sense the fallacious Marxist thesis of economic determinism.
