Nestabilnost optimalnosti i kalkulus rizika u Rescherovoj analizi racionalnosti / Instability of Optimality and the Calculus of Risk in Rescher’s Analysis of Rationality

This paper presents an analysis of Rescher’s conception of the mode of structuring and operation of human rationality, which Rescher approaches from a historical-philosophical, logical, and semantic matrix. The aim of this research is to explore the specific features of Rescher’s analysis of rationality through the lens of the instability of optimality and the calculus of risk, which emerge as essential presuppositions of his research. Rationality, understood in this context, has a threefold manifestation: as a procedural matrix, as a modus operandi, and as potential and materialization. This paper, drawing on Rescher’s original works and other relevant sources from the tradition of pragmatism, will explore his approach to this topic with a focus on what Rescher terms the instability of optimality and the calculus of risk.
