Umberto Eco in The Search for the Perfect Language explores the ‘dream of a perfect language’ that has sought to recapitulate the lost perfection of Adam's original language. Humanity is seen as forgetful of the preternatural knowledge once contained in a transparent language that perfectly identified essences. Eco's historical narrative of this pursuit, labeled “a series of failures,” is examined first. Then, Leibniz’s Adamicism is explored, which asserts that a language can be Adamic if it mirrors the natural and (...) non-arbitrary qualities of Adam's language. Cross-culturally, Sanskrit realism and Plato’s natural-name thesis support this, emphasizing the connection between words and meanings. Following this, the criteria for linguistic perfection (◊P) are established, relying on five necessary assumptions (A) concerning ontology, epistemology, accessibility, translatability, and intersubjectivity. This paper defends reconstructing an ideal language without seeking to return to the forever lost mother tongue. Instead, it assesses the potential for our current system-of-signs to regain semiotic realism and represent reality accurately. A thought experiment justifies returning to semiotic realism, examining the potential of revealing the hidden phenomenology of logos – the universal reason underlying all languages. Conclusively, this project rejects empirical nominalism and explores accessing the preternatural knowledge of necessary and immutable ideas, lost after the fall and Babel’s catastrophe. Keywords: adamic language, semiotic realism, logos, perfect language, linguistic naturalism, universals, essences, phenomenological method. (shrink)
