The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist.J. M. Keynes
The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design.F. A. Hayek
