The identity theory of truth takes on different forms depending on whether it is combined with a dual relation or a multiple relation theory of judgment. This paper argues that there are two significant problems for the dual relation identity theorist regarding thought's answerability to reality, neither of which takes a grip on the multiple relation identity theory.
