Idea
Social patterns such as language, markets and common law can arise from the actions of many people, none of whom intends or designs the overall result. Hayek, borrowing from Adam Ferguson, called them the result of human action but not of human design.
Theory
Hayek distinguished grown orders (cosmos) from made orders (taxis). In 'The Use of Knowledge in Society' (1945) he argued that knowledge is dispersed among individuals and that prices help coordinate it; in Law, Legislation and Liberty (1973–79) he treated rules of conduct as evolving through selection.
Real examples
Common examples are language, morality, the common-law system, money and markets; the Internet is also cited.
Critique
Critics note that grown orders can embed hierarchy and need not be efficient or just. Elinor Ostrom's work shows that successful local rules are often deliberately designed, monitored and enforced by users, not merely emergent.
Results
A framework for market-liberal and polycentric-law arguments rather than a single testable theory. It shapes the case for decentralised rule-making.

Claims
Hayek distinguished grown orders (cosmos), which are spontaneous, from made orders (taxis) deliberately arranged by a directing authority; he took the formula 'the result of human action but not of human design' from Adam Ferguson.[1][2]
