Beatrice Webb, the famous sociologist and political activist, reported in 1926: "'Every one agrees nowadays', observe the most noted French writers on the study of history, 'that it is advisable to collect materials on separate cards or slips of paper. . . . The advantages of this artifice are obvious; the detachability of the slips enables us to group them at will in a host of different combinations; if necessary, to change their places; it is easy to bring texts of the same kind together, and to incorporate additions, as they are acquired, in the interior of the groups to which they belong.'"

The term autopoiesis (from Greek αὐτo- (auto-) 'self', and ποίησις (poiesis) 'creation, production') refers to a system capable of producing and maintaining itself by creating its own parts.[1] The term was introduced in the 1972 publication Autopoiesis and Cognition: The Realization of the Living by Chilean biologists Humberto Maturana and Francisco Varela to define the self-maintaining chemistry of living cells.[2] Since then the concept has been also applied to the fields of cognition, systems theory, architecture and sociology.
