Knowning What We Can’t Know

The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design.  To the naive mind that can conceive of order only as the product of deliberate arrangement, it may seem absurd that in complex conditions order, and adaptation to the unknown, can be achieved more effectively by decentralizing decisions and that a division of authority will actually extend the possibility of overall order.  Yet that decentralization actually leads to more information being taken into account.
