Mises and Hayek Beginning with Ludwig von Mises and F.A. Hayek, the links between liberalism and the Austrian School become intense and pervasive, since these two scholars were themselves at once the outstanding Austrian economists and the most distinguished liberal thinkers of the twentieth century. The American academic world, however, deemed none of this sufficient for them to be accorded the kind of positions to which they were clearly entitled.50 They, and in particular Mises, were also responsible to a greater degree than is generally appreciated for the upsurge of the free-market philosophy in the second half of the century.51 But since the views of the two great men are so often amalgamated, it should be emphasized that not only did they differ to an extent on economic theory (Salerno 1993; see also Kirzner 1992c: 119–36), but, more pertinently to the theme of this essay, they exhibited a sharp distinction in the degree of their liberalism. What follows refers to Hayek’s political attitudes, not to his contributions to economic science. These were highly significant and valuable in the earlier part of his career, as he together with Mises built the theoretical foundations of the modern Austrian school.52 While Mises was a staunch advocate of the laissez-faire market economy (Mises 1978a; Rothbard 1988: 40; Hoppe 1993; Klein 1999), Hayek was always more open to what he saw as the useful possibilities of state action. He had been a student of Wieser’s, and, as he conceded, he was “attracted to him . . . because unlike most of the other members of the Austrian School [Wieser] had a good deal of sympathy with [the] mild Fabian Socialism to which I was inclined as a young man. He in fact prided himself that his theory of marginal utility had provided the basis of progressive taxation . . .” (Hayek 1983: 17). Early in his career, Hayek stated that the lessons of economics will create a presumption against state interference, adding: However, this by no means does away with the positive part of the economist’s task, the delimitation of the field within which collective action is not only unobjectionable but actually a useful means of obtaining the desired ends. . .the classical writers very much neglected the positive part of the task and thereby allowed the impression to gain ground that laissez-faire was their ultimate and only conclusion . . . (1933: 133–34) This remained Hayek’s standpoint throughout his long and richly productive scholarly life. It is regrettable, but typical, that a great many confused commentators continue to characterize him as a advocate of laissez-faire.53 In fact, he
