In Logical Forms Chateaubriand offers a realist semantics for false elementary propositions and for true negative propositions that appeals to negative facts. Although he does not refer to Wittgenstein, he rules out “possibilist” solutions such as that of the Tractatus. In this paper I will critically discuss Chateaubriand’s solution and compare it with the semantics of the Tractatus.
