A Conceptual Systems Theory: Information, Control, Adaptation, and Evidence-Bound Closure

Relationship to Existing Ideas This framework originates in the author's personal way of organising observations about the world and about systems. It is not presented as a claim of scholarly originality. Many of its components have clear counterparts in established fields, and the value of the framework may lie more in the way these ideas are brought together than in any individual concept. As an initial orientation, several parts appear to have parallels with existing traditions: The distinction between a system's actual state and what can be inferred from observations is closely related to the concept of observability in control theory. The emphasis on feedback, correction, and the controller's capacity to respond to system variation has connections with ideas developed in cybernetics, including work associated with W. Ross Ashby and Stafford Beer. The distinction between a physical carrier, detection, interpretation, and usable information can be viewed alongside ideas from information theory and semiotics, where transmission of signals and interpretation of meaning are treated as different problems. The idea of closure conditions - that a conclusion should only be treated as settled when specified conditions have been met - has conceptual parallels with approaches to warranted conclusions in epistemology, evidentiary reasoning, and engineering assurance. These parallels are not presented as a literature review or as claims of equivalence. They are simply reference points showing where this personal systems perspective appears to touch existing bodies of thought.
