This text explores the structural analogy between religious systems and the epistemological understanding of truth. The author draws a parallel between monotheism and polytheism on one hand, and the concept of a single, absolute truth versus a plurality of truths on the other. A significant historical distinction is identified: while ancient Greek thinkers allowed for diverse interpretations of first principles (archai) and deities without requiring binding loyalty, the Israelite prophetic tradition emphasized the "jealousy" of God. This insistence on absolute exclusivity was subsequently inherited by Christianity and Islam. The analysis highlights how this shift from ancient pluralism to religious exclusivism shaped the Western conception of truth as a singular entity. This comparative study focuses on the deep roots of Western thought, which perceives truth as an indivisible value. The author argues that while the Hellenistic tradition offered a more inclusive worldview, the Abrahamic religions consolidated a model where truth is bound to exclusive loyalty. This model influenced not only the religious sphere but also secular philosophical discourses on the nature of reality, effectively defining Western intellectual history.
