Although Hayek ascribed a primarily monetary source to economic fluctuations, he was not a monetarist as this term came to be used. - Alan O. Ebenstein

Hayek’s ultimate social goal—his utopia—was the unification of all humankind in one society.

Hayek’s move from economic theory to political philosophy was a natural evolution in his ideas. First, he considered the influence of prices in production.Then he considered the larger question of the role of prices in social life. The conclusion he reached was that law should guarantee to each person a protected sphere within which each could live as much as possible as he pleased. Later in his career, he progressed to the idea that whole societies through their customs, morals, and rules are engaged in macrocompetition, the survivor of which would possess the customs, morals, and rules that are the most materially productive and result in the highest standard of living for the most—the economist’s goal.

Hayek expressed more fully and deeply than Mises the epistemological argument for free market order. The crucial issue for Hayek became not that without prices individuals cannot calculate (though he thought this to be the case), but that the division of knowledge renders centralized control of an economy or society impossible.
