Frank Fukuyama’s recent review of Hayek’s Constitution of Liberty in the NYTimes has raised a ruckus in Hayekian circles. I review an older critique of Hayek by Ralf Dahrendorf and then lament the absence of the Hayekians in the great debate of the 1990s about socially engineering the transition from socialism to capitalism. Apparently the Hayekian strictures against utopian social engineering only applied to the transition in the opposite direction.
