Hayek: A Constituição da Liberdade

O New York Times comenta a nova edição de Hayek's "Constitution of Liberty": "... Hayek’s skepticism about the effects of “big government” are rooted in an epistemological observation summarized in a 1945 article called “The Uses of Knowledge in Society.” There he argued that most of the knowledge in a modern economy was local in nature, and hence unavailable to central planners. The brilliance of a market economy was that it allocated resources through the decentralized decisions of a myriad of buyers and sellers who interacted on the basis of their own particular knowledge. The market was a form of “spontaneous order,” which was far superior to planned societies based on the hubris of Cartesian rationalism. He and his fellow Austrian Ludwig von Mises used this argument against Joseph Schumpeter in a famous debate in the 1930s and ’40s over whether socialism or capitalism offered a more efficient economic system. In hindsight, Hayek clearly emerged the winner.
“The Constitution of Liberty” builds on this view of the limits of human cognition to make the case that no government can know enough about a society to plan effectively. The government’s true role is more modest: to create laws that are general and equally applied; these laws constitute the matrix in which the spontaneous interactions of individuals can occur. (It may, however, surprise some of Hayek’s new followers to learn that “The Constitution of Liberty” argues that the government may need to provide health insurance and even make it ­compulsory.) ..."
