What is meaning? The answer varies according to the methods of investigation and the applied philosophy. The book retraces the main stages of semantic research with an itinerary that is transversal to the disciplinary fields. The critical review progressively leaves room for theoretical considerations on the central themes of the language philosophy and the philosophy of mind. The path thus identifies the theses that build a systematic design: irreducibility of thought to language, rooting of semantic competence in kinaesthetic schemes, local holism, modularity recalibrated by lifting, emergence in terms of attractors, a beam model of the self, intertwined naturalism.
