Autonomy is the distinctive phenomology resulting from an autopoietic organization: the realization of the autopoietic organization is the product of its operation. As long as an autopoietic system exists, its organization is invariant: if the network of productions of components which define the organization is disrupted, the unity disintegrates. Thus an autopoietic system which has a domain in it which it can compensate for perturbations through the realization of its autopoiesis, and in this domain it remains a unity. (A 189)
Due to this organization a living system is an autonomous unity. (CS 460)
