Peter Abelard in his work presents a theory of virtue, which is, at first sight, of Aristotelian nature. It seems that this view also contains different Stoic elements, but they are not necessarily opposed to Stagirite's vision. However, the essentials of the Stoa School about virtue differ from the explanation given by Aristotle. In this paper, we intend to examine, first, the nature of virtue as habitus in Abelard's work on logic. In this case, there is no doubt that Aristotle's influence on this topic predominates. Next, we specify other features related to virtue found, this time, in ethical and theological treatises of our protagonist that appear to be basically Stoic. In short, we want to identify the different ancient sources and the main Latin mediators used by Abelard to elaborate his own theory of virtue. In other words, we would like to shed light on the predominant philosophical authority on Abelard's theory of virtue since this logician cannot harmonize theses that are fundamentally irreconcilable.
