 According to a second line of interpretation, a proposition is indeterminate in the relevant sense if the result of embedding it in some context is structurally ambiguous. Consider, for example, the result of embedding “F [A]” in the context “it is not true that,” where ‘A’ is temporarily treated as a semantically simple term designating a complex (Keep in place the assumption that a sentence containing a non-referring semantically simple term is neither true nor false). In this case the question would arise whether the result of this embedding is neither true nor false evaluated with respect to a world in which A does not exist, or simply true. The first option corresponds to giving the apparent name wide scope with respect to the logical operator, the second to giving it narrow scope. Such a scope ambiguity could not exist if ‘A’ were a genuine Tractarian name, so its presence could reasonably be taken to signal the need for further analysis.
