Abaelard invented the terminology of the de re – de sensu (de dicto) distinction and employed it with great skill in disambiguating modal claims. This seminar will discuss the role played by the distinction in Abaelard’s development of his de re theory of modality and in particular the question of whether he has an account of unrealisable possibilities.
