The term autopoiesis (), one of several current theories of life, refers to a system capable of producing and maintaining itself by creating its own parts. The term was introduced in the 1972 publication by Chilean biologists Humberto Maturana and Francisco Varela to define the self-maintaining chemistry of living cells.
The concept has since been applied to the fields of cognition, Neuroscience, systems theory, architecture and sociology. Niklas Luhmann briefly introduced the concept of autopoiesis to organizational theory.
Maturana and Varela explain that:
They describe the "space defined by an autopoietic system" as "self-contained", a space that "cannot be described by using dimensions that define another space. When we refer to our interactions with a concrete autopoietic system, however, we project this system on the space of our manipulations and make a description of this projection."
An autopoietic system is to be contrasted with an allopoietic system, such as a car factory, which uses raw materials (components) to generate a car (an organized structure) which is something other than itself (the factory). However, if the system is extended from the factory to include components in the factory's "environment", such as supply chains, plant / equipment, workers, dealerships, customers, contracts, competitors, cars, spare parts, and so on, then as a total viable system it could be considered to be autopoietic.
Autopoiesis in biological systems can be viewed as a network of constraints that work to maintain themselves. This concept has been called organizational closure or constraint closure and is closely related to the study of Autocatalysis where constraints are reactions required to sustain life.
Though others have often used the term as a synonym for self-organization, Maturana himself stated he would "never use the notion of self-organization ... Operationally it is impossible. That is, if the organization of a thing changes, the thing changes". Moreover, an autopoietic system is autonomous and operationally closed, in the sense that there are sufficient processes within it to maintain the whole. Autopoietic systems are "structurally coupled" with their medium, embedded in a dynamic of changes that can be recalled as sensory-motor coupling. This continuous dynamic is considered as a rudimentary form of knowledge or cognition and can be observed throughout life-forms.
An application of the concept of autopoiesis to sociology can be found in Niklas Luhmann's Systems Theory, which was subsequently adapted by Bob Jessop in his studies of the capitalist state system. Marjatta Maula adapted the concept of autopoiesis in a business context. The theory of autopoiesis has also been applied in the context of legal systems by not only Niklas Luhmann, but also Gunther Teubner.For a discussion on the evolution and development of autopoietic legal systems, see,
In the context of textual studies, Jerome McGann argues that texts are "autopoietic mechanisms operating as self-generating feedback systems that cannot be separated from those who manipulate and use them". Citing Maturana and Varela, he defines an autopoietic system as "a closed topological space that 'continuously generates and specifies its own organization through its operation as a system of production of its own components, and does this in an endless turnover of components, concluding that "Autopoietic systems are thus distinguished from allopoietic systems, which are Cartesian and which 'have as the product of their functioning something different from themselves. Coding and markup appear allopoietic", McGann argues, but are generative parts of the system they serve to maintain, and thus language and print or electronic technology are autopoietic systems.
The philosopher Slavoj Žižek, in his discussion of Hegel, argues:
Autopoiesis has been proposed as a potential mechanism of abiogenesis, by which molecules evolved into more complex cells that could support the development of life.
One question that arises is about the connection between cognition seen in this manner and consciousness. The separation of cognition and consciousness recognizes that the organism may be unaware of the substratum where decisions are made. What is the connection between these realms? Thompson refers to this issue as the "explanatory gap", and one aspect of it is the hard problem of consciousness, how and why we have qualia.
A second question is whether autopoiesis can provide a bridge between these concepts. Thompson discusses this issue from the standpoint of enactivism. An autopoietic cell actively relates to its environment. Its sensory responses trigger motor behavior governed by autopoiesis, and this behavior (it is claimed) is a simplified version of a nervous system behavior. The further claim is that real-time interactions like this require attention, and an implication of attention is awareness.
According to Razeto-Barry, the influence of Autopoiesis and Cognition: The Realization of the Living in mainstream biology has proven to be limited. Razeto-Barry believes that autopoiesis is not commonly used as the criterion for life.
Zoologist and philosopher Donna Haraway also criticizes the usage of the term, arguing that "nothing makes itself; nothing is really autopoietic or self-organizing", and suggests the use of sympoiesis, meaning "making-with", instead.
