“He who cares to go to the trouble of demonstrating the uselessness of index numbers for monetary theory and the concrete tasks of monetary policy will be able to select a good proportion of his weapons from the writings of the very men who invented them.”

Austrian economist and social theorist of the early-to-mid 20th century, Ludwig von Mises is best known for his rigorous defense of classical liberalism and free-market economics. His work in praxeology—an a priori method of social science—shaped modern libertarian thought, while his critiques of socialism and central planning remain foundational in economic theory.
