Hayek on the nature of the market order

From Chapter 10 of the second volume of his priceless Law, Legislation, and Liberty: 

“For a proper understanding of the character of this order it is essential that we free ourselves of the misleading associations suggested by its usual description as an ‘economy’. An economy, in the strict sense of the word in which a household, a farm, or an enterprise can be called economies, consists of a complex of activities by which a given set of means is allocated in accordance with a unitary plan among the competing ends according to their relative importance. The market order serves no such single order of ends. What is commonly called a social or national economy is in this sense not a single economy but a network of many interlaced economies.1 Its order shares, as we shall see, with the order of an economy proper some formal characteristics but not the most important one: its activities are not governed by a single scale or hierarchy of ends. The belief that the economic activities of the individual members of society are or ought to be part of one economy in the strict sense of this term, and that what is commonly described as the economy of a country or a society ought to be ordered and judged by the same criteria as an economy proper, is a chief source of error in this field. But, whenever we speak of the economy of a country, or of the world, we are employing a term which suggests that these systems ought to be run on socialist lines and directed according to a single plan so as to serve a unitary system of ends.”
