Abstract. The aim of this paper is first to defend the intuition that truth is grounded in how things are and, second, to argue that this fact is consistent with Minimalism. After having cashed out that intuition in terms of explanatory claims of the form ‘if it is true that p, it is true that p because p’, I set out an argument against Minimalism which is based on the same intuition, and I argue that a strategy the minimalist could adopt to resist the argument, i.e. to deny the correctness of the intuition, is flawed. Then I explain why the intuition is correct and I make some claims concerning the kind of explanations which are involved in it. Now the stage is set up to present the right way for the minimalist to resist the argument. I finally answer some objections.

According to Lynch’s aletich functionalism truth is manifested by/immanent in different properties in different domains of discourse; so a core concept of Alethic Functionalism is the concept of the relation of manifestation holding between truth and other properties. The claim I’m going to defend is that Lynch makes too many theoretical demands on the manifestation relation and this makes it a metaphysical monster, that is to say a relation with mutually inconsistent features. In order to make manifestation a coherent notion one should give up some of its original features, but this makes Alethic Functionalism a much less appealing theory than it was supposed to be.

La critica all’antirealismo costruttivista del pensiero postmoderno è al centro della riflessione di Maurizio Ferraris per lo meno a partire da Il mondo esterno (Ferraris 2001). Forme radicali di costruttivismo sono state però difese anche al di fuori del pensiero postmoderno tanto nella tradizione della filosofia analitica quanto, più recentemente, nell’ambito delle scienze cognitive. Nell’articolo viene dapprima presentata e criticata un’affermazione dal netto sapore costruttivista fatta da Vittorio Gallese e George Lakoff in uno degli articoli più influenti nel dibattito degli ultimi anni sulla natura dei concetti: The Brain’s Concepts (Gallese, Lakoff 2005). Tale posizione viene quindi messa in relazione con quella forma di antirealismo costruttivista, detta anche relativismo concettuale, difesa, in modi e con esiti diversi, da filosofi quali Nelson Goodman, Hilary Putnam e Richard Rorty. Si sostiene quindi che tutte queste forme di antirealismo costruttivista incorrono in un dilemma: o esse abbracciano la problematica tesi metafisica di un’efficacia causale a ritroso delle nostre menti sul mondo oppure si riducono a una plausibile, ma ontologicamente innocua, affermazione dell’esistenza, in linea di principio, di molteplici modi di categorizzare la realtà e, nel caso delle teorie cosiddette incarnate della cognizione, della dipendenza di tali modi dalle forme che assume l’interazione senso-motoria di un organismo col suo ambiente. Viene infine mostrato come dall’osservazione dei molteplici modi in cui è possibile categorizzare la realtà sia possibile trarre conclusioni metafisiche di segno opposto all’antirealismo costruttivista.

Although philosophers have been concerned with truth since at least the age of Plato, the last thirty years have witnessed a veritable explosion of the philosophical debate on this topic. The touchpaper which lit the fuse for this was undoubtedly the Deflationist Renaissance (half a century after the seminal work of F.P. Ramsey) due, in the Seventies, both to the Quinean disquotational interpretation of the Tarskian truth definitions and to the development of the prosentential theory of truth by D. Grover, J. Kamp and N. Belnap, and, from the second half of the Eighties onwards, to the forceful defences of deflationary conceptions provided by H. Field and P. Horwich. The philosophical struggle on deflationism has been thought-provoking: by arguing on the merits and shortcomings of such a conception, philosophers have come to broaden and deepen the discussion on truth beyond the boundaries of deflationism. The varieties of problems tackled by the essays in this book highlight how the land of Truth is still far from having been totally explored, and how, in this intellectual endeavour, real progresses can be achieved.
