“[I have] heard two sounds, one high and one low. !!When I described them to the engineer in charge, he informed me that the high one was my nervous system in operation, the low one my blood in circulation. !!Until I die there will be sounds.” !!(J.Cage 1961)

!!( . . . ) the device by which an organism maintains itself stationary at a fairly high level of orderliness (=fairly low level of entropy) really consists in continually sucking orderliness from its environment.”!!(E.Schrödinger 1944)

06/18An autopoietic machine is a machine (defined as unity) as a network of processes of production (transformation and destruction) of components that produces the components which: !!(i) through their interactions and transformations continuously regenerate and realize the network of processes (relations) that produced them; and
(ii) constitute it (the machine) as a concrete unity in the space in which they (the components) exist by specifying the topological domain of its realization as such a network” !!(Maturana and Varela, 1980)
SIX CRITERIALIFE AND SOUND
AUTOPOIESIS PROBLEMS THE
PROJECTEXAMPLES
!
07/18(1) There must be a (semi-permeable) boundary, that identifies the system from the point of view of the observer; (2) there must be identifiable components, as the parts that realize the system; (3) everything in the system must be described as a mechanism; (4) there must be a metric in order to realize interactions between components ruled by neighborhood, that create the boundary: (5) there are components that realize the boundary by means of the interactions between components or between components and elements that cross the boundary; (6) also components that are not directly involved in the realization of the boundary must be realized as in point 5 or must be present as a necessary component in the realization of other components.
