This document explores the terminological challenge of translating the English concept of "sensibility" into Czech. The author argues that existing Czech substitutes, such as "citlivost" (sensitivity) or "vnímavost" (receptivity), are inadequate due to their passivity and lack of active intentionality. Instead, the author proposes the term "reaktibilita" (reactibility), a concept borrowed from philosopher J. B. Kozák but redefined with greater precision and focus. This shift is essential to distance the term from the traditional physical interpretation of "reaction" as a mere consequence of a prior action. Strategically, the use of "reactibility" serves as a foundation for constructing an alternative to the unsustainable doctrine of pancausality. This doctrine, which derives the present solely from the past and the future from the present, is rejected in favor of a more nuanced understanding of temporal relations. By redefining reactibility, the author seeks to move beyond linear determinism and provide a framework that acknowledges active engagement with the world. The text thus contributes significantly to philosophical debates on causality, agency, and the limitations of linguistic expression.
