Preface: Scope, Validity, and Epistemological Position

Scientific theories are commonly discussed in terms of absolute truth or falsity, a framing that poorly reflects their actual use in scientific practice. In operational contexts, theories are better understood by their domain of validity: the range of scales and problem classes for which they provide stable and useful descriptions. This paper adopts that perspective and clarifies the epistemological scope of the Theory of Axiomatic Necessity (TNA). Rather than competing with established evolutionary frameworks, classical Darwinian theory included, the TNA is presented as a higher-order structural model concerned with the persistence of functionally necessary states across changes in material or genetic support. The paper argues that apparent conflicts between models often arise from category errors, specifically from conflating biological functions with the particular structures that implement them. The purpose of this work is not to offer a comprehensive biological theory, but to define a coherent conceptual framework for discussing functional persistence, structural turnover, and model complementarity within their respective domains of validity.
