Coupling

Definition

A generic term for dynamic intersystem engagement involving reciprocal effect, manifest "whenever the conduct of two or more unities is such that the conduct of each one is a function of the conduct of the others." (Maturana & Varela, 1980, p. 136)

Mode of protection from environmental disturbances by way of an isolating device.

This is not a regulation but merely an unilateral defence against some specific kind of environmental disturbance. An example is the shell of a tortoise.

[Coupling (of unities)]

Whenever the conduct of two or more unities is such that the conduct of each one is a function of the conduct of the others. (Maturana and Varela, 1979)

 

Encyclopedia Autopoietica

A generic term for dynamic intersystem engagement involving reciprocal effect, manifest "whenever the conduct of two or more unities is such that the conduct of each one is a function of the conduct of the others." (Maturana & Varela, 1980, p. 136) This is qualified by provision that the coupling unities maintain their identity throughout the engagement so labeled: "Coupling arises as a result of the mutual modifications that interacting unities undergo in the course of their interactions without loss of identity." (Maturana & Varela, 1980, p. 107)

The most important application of this term is structural coupling, wherein the coupling engagement reciprocally affects the structure of each engaged system.

[coupling (De-)]

Mode of protection from environmental disturbances by way of an isolating device.

This is not a regulation but merely an unilateral defence against some specific kind of environmental disturbance. An example is the shell of a tortoise.

Of course, this type of device prevents any interaction with the environment, included some that could be useful. The decoupling capacity is generally a property of the boundary of the system.
