ELOADASKIVONAT Someone could consider the topic of the models only an "old hat". Right in this way, someone could have thought after the analyses by R. Carnap, G. Hempel, E. Nagel, R. Braithwaite. But the criticisms by Hesse, Achinstein and Spector, and the proposals by Hesse herself and Black have shown that much more could be said; as, in these years, Redhead and Cartwright have pointed out, too. Each interpretation is a new point of view and each point of view permits to see new aspects, as Popper underlines. The interpretative way I will propose, based on fictions, a la H.Vaihinger, is different from both the semantical one and Hesse's analogical one. For this reason it should throw light on aspects till now neglected or considered insignificant. Nevertheless, the principal goal of my discussion will not be an attempt to give an entirely new theory of the models, but to insert a fictionalistic theory of them in a more general framework which deals with the counterfactuals, too. Obviously, this fact does not mean that I disregard the results achieved by the previous interpretations, specially by the analogical one. Here is a sketch of the talk: Introduction Models as fictions Models and empirical world A rough taxonomy of the models Fictions and counterfactuals A proposal for a different approach to the classical problem of the counterfactuals Az eloadas idotartama 50-60 perc, amelyet rovid szunet utan kb. 30-60 perc vita kovet.
