Abstract

F. Nietzsche does interesting indications on the anthropological foundation of language in his lessons on classical rhetoric, at the University of Basel in 1874. Many quotations of Gerber and Humboldt, and older notions, drawn from the Aristotle's Rhetoric are discussed in this dissertation. Many studies highlighted Nietzsche's attempts during thirty years (1976-2006) to draw a consistent anthropological foundation of the language. Some of them shed light on the metaphor, described from the point of view of anthropology, as an innovative perspective on the philosophy of rhetoric. Would metaphor be a verbal vehicles for conveying scientific and philosophical concepts by attaching unusual importance to the veracity or the truthfulness of a claim? Is that in contradiction to any conceptual truth? Some interpreters suggest that metaphors seen as linguistic products fail to explain the unnatural way meaning is transmitted from the unconscious musicality of language. If imperceptible bonds move the meaning of a word in the musicality of language, then to transmit a message by non verbal means or metaphors relates to a subjectively felt musicality of language. Meaning is expressed, not because there are words with fixed meaning in a conventional way, but because the word is seen in the first place as an action. Living language, seen as metaphorical by essence, is a view shared by German idealism, on the so-called origins of language. A consequence of this view on language is a wide reinterpretation of the reason, from the point of view of a rhetorical turn. Schopenhauer, Von Hartmann and Lichtenberg are some thinkers who pointed out the possibility of a pan-psychist notion of reason that inspired Nietzsche, and later Piaget (e. g. his theory of analogy is built on similar roots). A first part of this dissertation presents the historical genesis of doctrines that don't see language as an innate substratum of the conscious mind, but as rhetorical and conditioned by environment in the wide sense. In the second part, we read the main arguments of contemporary studies in cognitive sciences, discovering new structural similarities compared to the 19th Century views of Nietzsche. In the third part, we discuss the form of poetic imagination regarding a relation between metaphor and melancholy in Greek empirical medicine.
