Synthesized answer
The provided passages do not explicitly state which questions remain unanswered within the book "Intensional Logic and the Metaphysics of Intentionality."
However, the passages do indicate that Edward N. Zalta's work tackles issues related to intensional logic and intentional states, offering a unified explanation for inferential failures and grounding these phenomena in a single theory involving abstract entities that represent the contents of mental files [1, 2]. The book's description suggests that Zalta's intentional logic can analyze a wide variety of failures involving principles of substitutivity, existential generalization, and strong extensionality [1].

mental files and they play a crucial role in the analysis of the truth conditions of the sentences involved in the inference failures. The intentional logic Zalta develops, unlike others, can analyze a wide variety of failures involving the principles of substitutivity, existential generalization, and strong extensionality. A Bradford Book. Categories: Psychology Snippet: In this book, Edward N. Zalta tackles the issues that arise in connection with intensional logic and intentional states.
Title: Intensional Logic and Metaphysics of Intentionality by Edward Zalta Description: In this book, Edward N. Zalta tackles the issues that arise in connection with intensional logic and intentional states. In this book, Edward N. Zalta tackles the issues that arise in connection with intensional logic - a formal system for representing and explaining the apparent failures of certain important principles of inference - and intentional states - mental states such as beliefs, hopes, and desires, that are directed toward the world. His theory not only offers a unified explanation of the…
