Friedrich A. Hayek Defends a Solid and Natural Theory of Capital Against Frank Knight's Mythology of Capital

In the “The Mythology of Capital,” Hayek took on the long and bitter crusade against the Austrian theory of capital waged by Frank Knight, fifteen years Hayek’s senior, an eminent American economist and the founder and leader of the early Chicago School. Hayek fittingly adopted as the introductory quotation of his article a statement by Eugen von Böhm-Bawerk, not coincidentally the greatest economic disputant of the nineteenth century and Hayek’s chief influence in capital theory. Hayek’s quotation of Böhm-Bawerk read, “With every respect for the intellectual qualities of my opponent, I must oppose his doctrine with all possible emphasis, in order to defend a solid and natural theory of capital against a mythology of capital.” This is actually a concise statement of the early Hayek’s general method of attaining theoretical breakthroughs: he would carefully develop the correct theoretical position and then use it as a weapon with which to strike down the fallacies of his opponents. In this article he proceeded to demolish Knight’s claim that capital, once accumulated, was a permanent fund that perpetually and automatically reproduced itself without regard to human purposes and the prevailing conditions of scarcity. Hayek trenchantly characterized Knight’s notion of capital as “a pseudo-concept devoid of content and meaning, which threatens to shroud the whole problem in a mist of words.”
