“The illiterate expression ‘given data’ constantly recurs in Lange. It appears to have an irresistable attraction to mathematical economists because it doubly assures them that they know what they do not know. It seems to bewitch them into making assertions about the real world for which they have no empirical justification whatever.”

Austrian economist and philosopher

Friedrich August von Hayek was an Austrian economist and philosopher. He was a notable member of the Austrian school of economics, and is best known for his work in political economy, political philosophy, and intellectual history. He shared the 1974 Nobel Memorial Prize in Economic Sciences with Gunnar Myrdal for work on money and economic fluctuations, and for showing how economic, social, and institutional forces depend on one another. He is also widely remembered for his account of how prices convey information, an idea that became an important contribution to economics.
