This article reconstructs Abelard’s account of eternal truths as it is presented in the Dialectica, in the so-called Sententiae Parisienses, and in the Theologia “Scholarium.” It first shows how in the Dialectica Abelard had to transform the traditional account of topical inferences in order to make sense of the idea that true conditional propositions express eternal truths. It clarifies Abelard’s claim that eternal truths are grounded on the “nature of things” and explains why Abelard thought that these truths hold even (...) when there are no things. The article then considers Abelard’s reply to an objection according to which eternal truths have in fact been false in the past. It examines Abelard’s mature views on eternal truths as we find them in the Sententiae Parisienses and Theologia “Scholarium.” Here, Abelard grants the status of eternal truth also to what is expressed by contingently true categorical propositions. These truths are grounded on the “events of things” that exist eternally as the proposition-like objects of God’s will and foreknowledge. (shrink)
