Deriving De Re: In Favour of Moderate Uniformity

In the study of the ambiguities found in propositional attitude reports, the discovery of new interpretations led to the proliferation of semantic mechanisms stipulated to derive them. On the other hand, some authors have made attempts to reduce the number of those mechanisms. The present paper aims at a critical evaluation of some reductionist proposals, defending moderate unification that recognises two distinct mechanisms behind de re which both lead to genuine ambiguities.
