In "Wittgenstein in relation to his times" Von Wright1 poses a dilemma regarding the relationship between three wittgensteinian tenets: (i) the view that individual's beliefs and thoughts are entrenched in accepted language games and socially sanctioned forms of life (ii) the view that "philosophical problems are disquietudes of the mind caused by some malfunctioning in the language games, and hence in the way of life of the community". (iii) the "rejection of the scientific-technological civilisation of industrialised societies". The dilemma is the following: is Wittgenstein's rejection of technological civilisation strictly linked to his general view of philosophy? Or is it "only contingently - that is for historical and psychological reasons, connected with the other two in Wittgenstein's thought"? Von Wright argues, even with some doubts, for a strong link between Wittgenstein's rejection of technological society and his general approach to philosophy; the argument is as follows: "because of the interlocking of language and ways of life, a disorder in the former reflects disorder in the latter. If philosophical problems are symptomatic of language, producing malignant outgrowths which obscure our thinking, then there must be a cancer in the Lebensweise, in the way of life itself" (p.119). The argument seems to be not compelling; among some of the main philosophical problems Wittgenstein is willing to "cure" there are misunderstandings lying in the history of our language much time before our technological civilisation (Wittgenstein refers to Augustine and Plato as suffering these disorder of language). We should generalise the criticism to technological society to the effect of enclosing ancient Greece. In this way the criticism seems to loose all its polemical vein, becoming a generic criticism of the structures of western thought since Greece. But probably this was the point Wittgenstein wanted to make in his criticism of the idea of progress and technological civilisation. I will argue therefore for the second horn of the dilemma, relying on another kind of de facto argument: contemporary technological civilisation is embodying some of Wittgenstein's main ideas (we might also note that these ideas are among the strongest points Wittgenstein gives against Greek classical tradition in philosophy)..

Is deduction of use in application to our everyday problems? Aristotle said that in practical matters we cannot use a strictly deductive attitude: "we must be content...in speaking about things which are only for the most part true, with premises of the same kind, to reach conclusions that are no better" (Nic.Eth.I,4 - my underlining). We may content ourselves with conclusions which - according to the usual views - are not true; but what happens when we realize that such conclusions bring us into contradiction with some of our deepest beliefs? We have to pursue our search of rationality in the most compelling manner, and this effort forces us to express our background beliefs in order to check what may be wrong with that. In this paper I will give two classical examples, one form the history of cinema and another from the history of artificial intelligence: in comparing these two examples I claim that logical compulsion - the deep need for convention - is highly valuable where feelings are not enough

In questo saggio non sviluppo una tesi precisa, ma presento alcune osservazioni sull'olismo e molecolarismo che tentano di mostrare la praticabilita' del molecolarismo e vederne allo stesso tempo le difficoltà: (i) Mi interrogo sulla fortuna del dibattito sull'olismo degli ultimi anni, come ripresa e precisazione delle osservazioni fatte a suo tempo da Dummett nel suo libro su Frege. (ii) Richiamo alcune idee fregeane a proposito di linguaggi formali che definiscono una specie di olismo innocuo, e al contempo impongono una distinzione tra olismo del significato e della competenza. (iii) Pongo il problema dell'allargamento di tali idee dai linguaggi formali al linguaggio naturale; propongo di applicare la distinzione tra significato e competenza alla differenza tra significato socialmente costruito e significato usato dai singoli; in tal modo individuo nell'idea di ''idioletto'' di Frege un problema cui ogni teoria del linguaggio deve rispondere. (iv) Sostengo che il molecolarismo risponde al problema dell'idioletto; difendo percio' la praticabilita' del molecolarismo messa in discussione dal saggio di Fodor e Lepore, in cui cerco di individuare il punto in cui hanno fuorviato il lettore nel credere alla impraticabilita' di tale prospettiva. (v) Sopo aver accennato ad alcuni problemi aperti nella proposta molecolarista di Dummett, presento una possibile interpretazione non olistica del pensiero di Wittgenstein, che pero' non risolve i problemi sopraccennati.

[This is a larger version of the published article] In the discussion on semantic holism it has been claimed that A.I. is almost entirely holistic. In this paper I show that some of the main lines of research in symbolic artificial intelligence are not holistic; I will consider three classical cases: toy words, frames and contextual reasoning. I claim that these examples from A.I. can be interpreted as implementing molecularist intuitions about language. Eventually I suggest that some assumptions behind the discussion on holism should be re-interpreted, expecially the usual references to Frege and Wittgenstein.

This volume contains essays that explore explicit and implicit communication through linguistic research. Taking as a framework Paul Grice's theories on "what is said," the contributors explore a number of areas, including: the boundary between semantics and pragmatics; the concept of implicit communication; the idea of the logical form of our assertions; the notion of conventional meaning; the phenomenon of deixis, which refers to when an utterance require context in order to be understood fully; the treatment of definite descriptions; and the different kinds of pragmatic processes.

In this paper we give some theoretical links between the wittgensteinian strategy of language-games and the strategy followed by students in Artificial Intelligence in the seventies. We refer also to the interpretation given by Dummett and Prawitz to the Wittgenstein's slogan of "meaning as use", showing the link of this ideas with the needs of Artificial Intelligence. We sustain that the concept of "procedure" as developed in early Artificial Intelligence is still one of the main attempt, realized in that field of research, to give a definition of meaning , which gives good hopes to be a suitable explicatum of the idea of "meaning as use".

Lexical Competence si presenta come una analisi dei diversi aspetti del del concetto di competenza semantica, con contributi originali sull'aspetto referenziale e sui problemi al margine tra filosofia e intelligenza artificiale. La pacata analisi del concetto di competenza lessicale porta a criticare tesi filosofiche sostanziali: le teorie oggettivistiche del significato alla Putnam tendono a ipostatizzare le norme semantiche, e le teorie naturaliste alla Chomsky tendono a dare poco o nessuno spazio agli aspetti normativi del linguaggio. Marconi cerca una terza via e le sue critiche agli argomenti di Putnam, Burge, Chomsky, Bilgrami e altri sono devastanti. E' difficile per me fare una critica su cio' che mi trova fondamentalmente d'accordo; ma una tesi che attraversa tutto il libro di Marconi mi e' sembrata invece piu' problematica di quanto appare a prima vista. In quanto segue cerchero' dunque di dare voce ai miei dubbi su questa tesi, restringendo la mia attenzione all'aspetto inferenziale della competenza lessicale. La tesi generale sotto discussione si puo' cosi' riassumere.

In this paper, I discuss some of Maximilian de Gaynesford’s arguments regarding indexicals. Although I agree with his treatment of the first singular personal pronoun as a prototype of demonstrative expressions, I challenge his refusal to treat indexicals as complex demonstratives. To offer an alternative to this refusal I try to develop a common ground from different theories that consider indexicals as linguistic constructions that embed a nonlinguistic element, following an original idea in Frege’s latest writings. These views form the backdrop on which we can put forward the claim of treating all indexicals as complex demonstratives. In the central part of the paper, I criticize each of de Gaynesford’s arguments against the reduction of indexicals to complex demonstratives. Besides, I propose a new definition of the concept of “demonstration” as a nonlinguistic feature of all indexicals in their referential uses, to contrast de Gaynesford’s rejection of the idea that demonstrations are an essential feature of indexicals. Eventually, I strengthen my claim by distinguishing indexicals from proper names and definite descriptions on the ground that only perceptual indexicals necessarily require an accompanying demonstration. However, the main point of the paper is a negative one, that is the rejection of de Gaynesford’s arguments against the reduction of indexicals to complex demonstratives. More work is needed to reach a positive conclusion on this topic.
