SummaryHaving termed any physical difference a “signal” and having methodologically distinguished the ambit of syntactic rules from that of the semantic references, we regard the relations between these signals as lying on a single plane, without distinction between concepts, objects and expressions. Signals‐significants and meanings at the same time‐are the nodes of a network of connections whose syntactic and semantic aspects are inseparable. Thus: 1. we reject the critique of AI that claims it is necessary to separate semantics from syntax; (...) 2. we define the conditions for adequate scientific communication. (shrink)
