Lo statuto dei simboli nella Vienna neoempirista. L'Organonmodell di Buehler rivisitato oggi

If contexts are relevant to communication, making pronouncements on metaphysics may benefit from a focus of attention on the location in which they are articulated and on its historical memory. The Italian reception of logical positivism makes a significant step in Milan where it finds two conscientious and critical representatives in Geymonat and Rivetti Barbò. The focus then moves upstream, on towards Vienna, and to the development of axiomatic models which are very different from each other. The fame of the Vienna Circle had long surpassed that of Bühler, the most philosophical Prague Circle author, however semiotics, or sematology, is an area of inevitable comparison between the two schools. Through the reconstruction of conferences in Prague, Vienna and Hamburg, the theoretical foundation of symbols is discussed – at the limit of asemanticity in formal languages it is, however, laden with diversified sign functions in the constructs of natural language. In conclusion, the anti-metaphysical debate must be remodelled on the basis of a two-dimensional semantics and be able to restore the dialogic nature of conflicts.
