Oben Abb. 8). 34 1. Kapitel: Aussagenlogische Strukturen Allerdings bedarf es, um dies zu erkennen, einer geringfugigen Umdeutung der Wahrheitswerte in Möglichkeitsvorstellungen (des Täters). Diese Umdeutung ist deshalb nur geringfügig, weil schon die Wahrheitswerte „wahr" und „falsch" sich eigentlich auf „Wahrheitswertmöglichkeiten" beziehen (vgl. oben Fn. 4 und 5). Um dies deutlich werden zu lassen, wird in der in Abb. 14 wiedergegebenen Tafel deshalb statt „w = wahr" bzw. „f = falsch" nunmehr „+ = möglich" und „- = unmöglich" gesetzt.
