itselfa

Itselfa is a theoretical concept used in cognitive science, philosophy of mind, and artificial intelligence to describe the capacity of a system to reference and regulate itself through internal models and feedback processes. It is not a concrete technology, but a family of properties associated with self-referential organization and self-modification in both natural and artificial agents.

The term combines 'itself' with a suffix -a to indicate reflexivity. Its precise definition varies among scholars, and there is no single formal criterion. In some usages it refers to self-modeling: an internal representation of the system's own state and goals; in others, to processes that preserve identity over time, despite change in components or environment. It is commonly discussed in contexts ranging from autonomous robots to living organisms capable of adaptive regulation.

Characteristics and relationships. Typical features include an internal state representation, monitoring of estimation errors, and the ability to initiate changes to align actual states with predicted or desired states. Itselfa often intersects with ideas of meta-learning, self-organization, and homeostasis, and may be examined in relation to concepts such as autopoiesis and self-awareness.

Criticism and use. Some critics argue that it uses anthropomorphic language for abstract dynamical properties. Proponents contend that it provides a useful umbrella for analyzing self-directed behavior and identity continuity in complex systems. As a theoretical construct, itselfa appears mainly in thought experiments and modeling work rather than as an agreed-upon, implemented standard.
