Regarding social order, [Francis] Fukuyama writes, "The systematic study of how order, and thus social capital, can emerge in spontaneous and decentralized fashion is one of the most important intellectual developments of the late twentieth century." He correctly attributes the modern origins of this argument to F. A. Hayek, whose pioneering contributions to cognitive science, the study of cultural evolution, and the dynamics of social change put him in the forefront of the most creative scholars of the 20th century.
