Abstract

In the course of the debates on Priscian's notion of the perfect sentence, the philosopher Peter Abelard developed a theory that closely resembles modern accounts of propositional attitudes and that goes far beyond the established Aristotelian conceptions of the sentence. According to Abelard, the perfection of a sentence does not depend on the content that it expresses, but on the fact that the content is stated along with the propositional attitude towards the content. This paper tries to provide an analysis and a consistent interpretation of Abelard's arguments within the framework of the mediaeval models of language and mind.
