This text explores the relationship between Truth and Logos, emphasizing that Truth requires Logos as a specific medium to influence the unfolding of events. Reflecting on Spinoza's assertion that truth is the criterion of itself and of falsehood, the author argues that a 'Truth about Truth' is inherently impossible. Instead, Truth functions as a transcendental norm for all relative authenticity, truthful statements, and human actions. For this norm to manifest in the world, it must be mediated through Logos, which transforms Truth into an addressing challenge or call. Human actions are not direct executions of Truth itself, but rather responses to its address. Thus, Logos enables specific events to become, through their occurrence, an authentic answer to the challenge of Truth. The text defines the ontological role of the word and reason in the process of realizing truthfulness within historical movement, where Truth remains a purely non-objective yet formative force.
