Γράμμα, σύμβολον, σημεῖον nella Grecia del V secolo
Greek Philosophers have formulated two kinds of theories about language: the ones about phonic-graphic forms (γράμμα) and their relations; and the theories of sign, enquiring how knowledge is realised by valid discourse structures (λόγος). The difference between such linguistic theories is overshadowed by the fact that terms belonging to the two different theories occurs in the same texts apparently discussing the same subject-matter (σύμβολον, ὄνομα, σεμεῖον). This essay tries to demonstrate that such co-occurrences depend on the sign theorist’s need of quoting and confuting the other theories. And some very famous Greek philosophical text on language can be interpreted from this point of view.
