The transcript presents a phenomenological and philosophical analysis of the concepts of "environment" (osvětí/Umwelt) and "world," drawing on the work of Martin Buber. The author distinguishes between the animal environment, which is closed and functionally limited, and the human world, defined by its essential openness. This openness is achieved through entry into the world of speech. While animals remain "enchanted" within their biological surroundings, humans are born "onto the world," a distinction reflecting freedom and dialogue. Central to the discussion is Buber's thesis on the twofold human attitude expressed through the primary words "I-Thou" and "I-It." Using the example of a child first calling out to its father, the text illustrates that language is not merely a label for objects but a constitutive act that establishes an existential relationship. Addressing another with one's whole being in an I-Thou relation creates a space of reciprocity where the individual truly becomes human. Ultimately, the world is viewed not as a "storehouse of things" but as a dynamic network of relations and meanings opened through language.
