Chapter 4: Language, Truth and Music

Language, Truth and Music establishes a critical epistemological distinction between two modes of knowledge: kennen, a right-hemisphere modality characterized by personal, holistic, and evolving acquaintance with the "Other," and wissen, a left-hemisphere modality focused on fixed, factual, and impersonal data. The analysis challenges the assumption that language drove brain lateralization, presenting paleoanthropological evidence—such as the size of the hypoglossal canal in early hominids—to suggest that the capacity for complex vocal control and "musilanguage" existed long before the emergence of syntax. Central to the argument is the concept that thought does not require language; evidence from animal cognition, aphasia studies, and creative problem-solving demonstrates that categorization and reasoning function independently of verbal signs. The text explores the intimate neurological link between the left hemisphere's control of the right hand and the development of referential language, proposing that both are driven by a desire to "grasp," manipulate, and utilize the environment (an "I-It" relationship) rather than to communicate empathically (an "I-Thou" relationship). Furthermore, the vital role of metaphor is examined as the only means by which language maintains its roots in embodied experience, a function exclusive to the right hemisphere. The chapter concludes by discussing the competitive nature of the left hemisphere, which tends to inhibit the right hemisphere's broader, contextual awareness to achieve functional efficiency, potentially leading to a fragmented understanding of reality.
