In order to construct an anthropologically unbounded account of posthumans, we need a psychology-free account of value. There may, after all, be many possible posthuman psychologies but we don’t know about any of them to date. However, the theory requires posthumans to be autonomous systems of a special kind: Functionally Autonomous Systems (see below). I understand “autonomy” here as a biological capacity for active self maintenance. The idea of a system which intervenes in the boundary conditions required for its existence can be used to formulate an Autonomous Systems Account of function which avoids some of the metaphysical problems associated with the more standard etiological theory. The version of ASA developed by Wayne Christensen and Mark Bickhard defines the functions of an entity in terms of its contribution to the persistence of an autonomous system, which they conceive as a group of interdependent processes (Christensen and Bickhard 2002: 3). Functions are process dependence relations within actively self-maintaining systems.
Ecological values are constituted by functions. The conception, in turn, allows us to formulate an account of “enlistment” which then allows us to define what it is to be an FAS.
1) (ASA) Each autonomous system has functions belonging to it at some point in its history. Its functions are the interdependent processes it requires to remain autonomous at that point.
2) (Value) If a process, thing or state is required for a function to occur, then that thing or process is a value for that function. Any entity, state or resource can be a value. For example, the proper functioning of a function can be a value for the functions that require it to work.
3) (Enlistment) When an autonomous system produces a function, then any value of that function is enlisted by that system.
4) (Accrual) An FAS actively accrues functions by producing functions that are also values for other FAS’s.
5) (Functional Autonomy) A functionally autonomous system (FAS) is any autonomous system that can enlist values and accrue functions.
People are presumably FAS’s on this account, but also nonhuman organisms and (perhaps) lineages of organisms. Likewise, social systems (Collier and Hooker 2009) and (conceivably) posthumans. To date, technical entities are not FAS’s because they are non-autonomous. Historical technologies are mechanisms of enlistment, however. For example. Without mining technology, certain ores would not be values for human activities. Social entities, such as corporations, are autonomous in the relevant and sense and thus can have functions (process interdependency relations) and constitute values of their own. However, while not-narrowly human, current social systems are wide humans not posthumans. As per the Disconnection Thesis: Posthumans would be FAS’s no longer belonging to WH (the Wide Human socio-technical assemblage – See Roden 2012).
This is an ecological account in the strict sense of specifying values in terms of environmental relations between functions and their prerequisites (though “environment” should be interpreted broadly to include endogenous and well as exogenous entities or states). It is also an objective rather than subjective account which has no truck with the spirit (meaning, culture or subjectivity, etc.). Value are just things which enter into constitutive relations with functions (Definition 2 could be expanded and qualified by introducing degrees of dependency). Oxygen was an ecological value for aerobic organisms long before Lavoisier. We can be ignorant of our values and mistake non-values for values, etc. It is also arguable that some ecological values are pathological in that they support some functions while hindering others.
The theory is partial because it only provides a sufficient condition for value. Some values – Opera, cigarettes, incest prohibitions and sunsets – are arguably things of the spirit, constituted as values by desires or cultural meanings.

 An issue I do not have time to consider is that ecological dependency is transitive. If a function depends on a thing whose exist depends on another thing, then it depends on that other thing. Ecological dependencies thus overlap.
