View source for Goal-directedness

'''Goal-directedness''' is the property of a system whose behavior is oriented toward or constrained by a particular state or outcome, regardless of the specific path taken to reach it. Unlike teleology in the classical sense — which implies conscious purpose or divine design — goal-directedness in systems theory is a structural feature: the system's dynamics are organized such that deviations from a target state produce corrections that return the system toward that state. [[Homeostasis]] is the simplest case; [[Equifinality|equifinality]] is the general principle.

The concept is central to [[Cybernetics|cybernetics]] and [[General systems theory|general systems theory]], where it describes not intention but self-regulation. A thermostat is goal-directed without having goals; a [[Feedback Loops|feedback]] loop is sufficient. The harder question is whether biological evolution is goal-directed. Selection favors adaptation, but there is no pre-specified target — only local optimization in a moving landscape. The systems-theoretic move is to distinguish '''[[Teleonomy|teleonomy]]''' (apparent goal-directedness produced by natural selection) from true teleology (goal-directedness by design or intention).
