“All that the State need do, and can do, in order to preserve the monetary system undisturbed, is to refrain from such intervention. That is the essence of the monetary theory of the classical economists and their immediate successors, the Currency School. It is possible to refine and amplify this doctrine with the aid of the modern subjective theory; but it is impossible to overthrow it, and impossible to put anything else in its place. Those who are able to forget it only show that they are unable to think as economists.”

Austrian and American political economist and philosopher

Ludwig Heinrich von Mises was an Austrian and American political economist and philosopher of the Austrian school. He is known for his work on classical liberalism and the place of consumers in a market economy. He wrote and lectured widely on the social value of classical liberalism, and on praxeology, the study most closely associated with his work. He is also known for comparing communism and capitalism, and for defending liberal ideas against the spread of illiberalism and authoritarianism in 20th-century Europe.
