This text examines Emanuel Rádl's conception of truth, emphasizing his unique, albeit initially unconventional, formulations. Rádl, originally a biologist, intensely engaged with philosophy in his later life, particularly the question of truth. His view diverges from traditional intellectualism and subjectivism. Rádl stresses "living truth," which is not mere knowledge but an active force that guides individuals and gives meaning to their lives. This truth is not actively created by humans but reveals itself to them and calls to them. The text further analyzes Rádl's critique of traditional philosophy, which, in his view, neglects life practice and prioritizes abstract knowledge. It highlights that for Rádl, the primary aspect is the "execution of truth" through action, rather than its comprehension. An individual's relationship with truth begins with its realization, often without full awareness, and only secondarily does reflection and knowledge come into play. The author attempts to interpret Rádl's ideas and demonstrate their deeper meaning, which connects to ancient traditions (e.g., 3 Esdras) and links truth with faith as trust and responsibility towards "what is right." The text also touches upon Rádl's influence on contemporary thought, comparing him with other Czech thinkers.
