The full definition, "Virtue is a good quality of the mind by which one lives correctly, which no one uses wrongly, and which God produces in us without us," is the common medieval definition of virtue. (Cf. S.T., I-II, 55, 4, obj. 1). Lottin traces some of the history of this definition in RSPT, XVIII (1929), 371-72. Peter of Poitiers seems to have been the first to use the definition in exactly its present form.
