Abelard and Heloise’s exchange of letters is known more for its love story and literary qualities than for the philosophical themes running through it. The aim of this essay is, therefore, to propose a "philosophical" reading of the letters. In the correspondence between the two, a recurrent and decisive element are some crucial problems in ethics, logic and Abelardian theology. They are the role of the word and the relation between voice and significatio; ethical questions such as the opposition between intention, or meaning of action, and exterior compliance with the Law; the connection between analogy and continuity among pagan philosophers and Christian hermits; the depreciation of the exercise of repetition (consuetudo) and of the literal interpretation of religious rules, which leads to empty words in teaching and to meaningless prayers in worship. All of this points to the philosophical unity of Abelard’s work from his autobiography to the texts on logic, ethics and theologies.
