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 is the general principle.

The concept is central to cybernetics and general systems theory, where it describes not intention but self-regulation. A thermostat is goal-directed without having goals; a 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 (apparent goal-directedness produced by natural selection) from true teleology (goal-directedness by design or intention).
