Truth I 128
"True in the other possible world"/Operator/Cresswell: ambiguous: ((lx)Ofx: "is such an x that x f is in the other world" - then: ((lx)Ofx)(s): the thing x (in this world, actual world) has the complex property of being wooden in the other possible world) - ambiguous: a) it is true in the other world that it is true in the other world that the largest wooden building is wooden. This can simply be represented like this: O(O(fs)).
- b) if the parentheses are omitted: OOfs: then it is equivalent to fs. - This is appropriate for (18) and certainly also for all specific descriptions. - Problem: then all the laws of classical logic do not longer apply.
II 72
Definition true/Truth/Possible World Semantics/Cresswell: a sentence is true in a possible world iff this world is in the sets of worlds that is its intension (of the sentence). - ((s): inversion of the definition of extension: extension of the sentence: set of worlds in which it is true). Cresswell: therefore one can say that the extension of the sentence is its truth value. (Frege).
