Persistence Selection Theory: A Framework Overview Across Four Papers

This paper is an overview of the Persistence Selection Theory (PST), a theoretical framework developed across four connected papers. The framework addresses a single underlying question: why does the universe contain persistent, orderly structures at all, and why do these structures—across biology, language, institutions, and software—exhibit similar organizational features such as multi-layering, feedback, and the maintenance of homeostasis? The framework's answer proceeds without invoking design, purpose, or teleological direction. It rests on a single observation: what cannot persist is eliminated, and whatever remains available for observation has, by the simple fact of remaining, passed through this selection. The four papers constituting PST are organized as a vertical integration. The first, A Precursor Theory of Stabilization (Vaernes, 2025a), establishes the ontological foundation by arranging observable substrates—from atoms to protocells—along a sequence in which physical robustness decreases while compensatory mechanisms proliferate, and by reframing this stabilization gradient as a consequence of a persistence imperative inherent to the universe. The second, Adaptation Across Substrates (Vaernes, 2025b), provides the generative dynamics: structures subjected long-term to opposing pressures of variation and conservation come to carry an internal distribution of mutation rates and, through this distribution, become multi-layered with functionally specialized layers. The third, Feedback Loops as an Observational Framework (Vaernes, 2025c), supplies the observational language in which these structures can be described, treating "process" not as a claim about mechanism but as an explanatory hypothesis introduced to render observed circulations coherent. The fourth, Wiener Revisited (Vaernes, 2025d), places the framework within the history of ideas by reframing Norbert Wiener's 1948 universality thesis as a consequence of the selection-based observational stance developed in the third paper. This overview paper has four aims. It names the framework, summarizes each of the four papers and their role in the vertical integration, recommends a reading order, and clarifies what PST is and what it is not. It also situates PST within the longer tradition of cross-domain structural theories—cybernetics, general system theory, dissipative structures—not to claim priority over these predecessors but to indicate which of their concerns PST inherits and which it leaves aside. The paper concludes with a statement of scope and limits: PST is offered as a conceptual framework for the redescription of persistent structures under a non-teleological vocabulary, not as a source of empirical predictions, and its evaluation should proceed accordingly.
