A sokvilág-interpretáció bemutatása
(On the many-world interpretation of quantum mechanics)
Hugh Everett javasolta először a kvantumfizika sokvilág interpretációját. Azóta sokan foglalkoztak a témával, és sokféleképpen értelmezték azt.
A diplomamunka célja tárgyilagosan bemutatni az egyes értelmezéseket, megvilágítani a sokvilág interpretáció eltéréseit a többitől, valamint megvizsgálni a lehetséges bizonyítási eljárásokat.

Rudolf Carnap’s Logische Syntax der Sprache (1934) is usually taken as a landmark both in the history of logical empiricism and twentieth century analytic philosophy. For a long time, one aspect of the book, namely the principle of tolerance, PoT, was just simply neglected. Recent scholarship, however, has considered it to be one of the most important achievements of Syntax. Such scholars as Michael Friedman, Thomas Ricketts, André Carus, Stewe Awodey tried to focus on the overwhelming technical and philosophical consequences of PoT, furthermore others, such as Thomas Uebel, has shown its historical context in the Vienna Circle.

In my presentation I shall defend the following thesis: even if we acknowledge the important influence of Hans Hahn, Karl Menger and Otto Neurath on the PoT, and even if we try to uncover its underlying ideas from the point of view of Russell and Wittgenstein, we still miss something very important. Those explanatory elements which I shall focus on are the Weltanschauung and cultural heritage of the young Carnap from his time in the German Youth Movement, the Jugendbewegung.

My thesis is that in order to obtain Carnap’s famous PoT we have to extend the limits of Russell’s pragmatic-inductive considerations regarding logic put forward, for example, in Principia Mathematica. To do this, Carnap has accepted the idea of Wittgenstein, namely that logic is empty of any empirical content. Since logical is tautological (which Russell has denied) we seem to have the relevant freedom to formulate PoT. Wittgenstein, however, did not draw the same conclusion, so have to deal with the question that what did Carnap have that Wittgenstein didn’t? The answer could be found around Carnap’s time in the German Youth Movement.
