Their narrative, however exceptional. [fact]
But Hayek and Friedman, along with their colleagues in the Mont Pèlerin Society, incontrovertibly played a role in the formation of that network of presuppositions that Dicey referred to as the “spirit of an age.” Their narrative, however exceptional, provides an implicit rebuke to the fatalism engendered by encounters with the real. Ideological changes require individuals who can continue to believe, against good evidence, that actions will at some point catch up with their ideas.
