Noēsis: Model of Guidance for Reasoning in the Achievement of Purpose

This article grounds Noēsis as a conceptual model for orienting reasoning toward the realization of a purpose. It assumes that all action-oriented reasoning is structurally organized through internal relations between end, mediations, and criteria for recognizing realization. Drawing on the philosophical tradition of finality and on theories of rationality, Noēsis is described as an elementary conceptual architecture composed of four articulated functions: a) purpose, as the organizing principle that unifies and directs the rational course; b) means or instruments, as mediations selected in function of the purpose; c) degree of quality and inventiveness, as the functional evaluation of the realization of the purpose according to criteria of adequacy and pertinent variation; and d) degree of certainty, as the conceptual closure that recognizes the effectiveness of realization. These functions operate relationally and sequentially, with each presupposing the previous one and preparing the subsequent one, configuring an internal dynamic of finalistic reasoning that preserves logical coherence, semantic stability, and conceptual auditability. Noēsis is not presented as a method, technique, or operational instrument, but as a conceptual architecture intended to render intelligible the orientation of reasoning toward purpose, independently of the domain of application or the content of the objective. As a theoretical contribution, the article establishes Noēsis as a universal conceptual framework for understanding and qualifying action-oriented reasoning, enhancing cognitive precision in contexts of decision and action, while preserving the distinction between conceptual orientation, mediation, evaluation, and rational closure.
