Abstract
</SectionTitle>
    <Paragraph position="0"> Ambiguities related to intension and their consequent inference failures are a diverse group, both syntactically and semantically. One particular kind of ambiguity that has received little attention so far is whether it is the speaker or the third party to whom a description in an opaque third-party attitude report should be attributed. The different readings lead to different inferences in a system modeling the beliefs of external agents.</Paragraph>
    <Paragraph position="1"> We propose that a unified approach to the representation of the alternative readings of intension-related ambiguities can be based on the notion of a descriptor that is evaluated with respect to intensionality, the beliefs of agents, and a time of application. We describe such a representation, built on a standard modal logic, and show how it may be used in conjunction with a knowledge base of background assumptions to license restricted substitution of equals in opaque contexts.</Paragraph>
