Abstract

Dieser Beitrag wirbt f³r den "logischen" Ansatz in der Spieltheorie, der eine Formalisierung der jeweils verwendeten Annahmen beinhaltet und dabei auch Alternativen zur ³blicherweise stillschweigend vorausgesetzten Logik in Betracht zieht. Nach einigen philosophischen Vorbemerkungen wird dargestellt, wie etwa "epistemische" Logik eingesetzt werden kann, um die Annahme zu formulieren, da▀ " die Struktur des Spiels" bekannt ist. Es zeigt sich, da▀ diese Annahme Unterschiedliches bedeuten kann, und da▀ sich entsprechend unterschiedliche Aussagen ³ber den Zusammenhang zwischen "Rationalitõt" und "backward induction" ergeben. Im letzten Abschnitt wird erlõutert, warum das in der ³blichen mathematischen Logik verwendete "Substitutivitõtsprinzip" im Kontext von Aussagen ³ber Wissen oder Glauben nicht plausibel ist.
