Peter Lombard, who is commonly called the Master of the Sentences, in book 2, and the Scholastics who followed him, held these works to be undoubtedly works of the Areopagite. Therefore they always praised his sayings about the celestial hierarchies, about the divine properties, and other matters, as established and most highly to be venerated. Apart from Thomas de Vio, I have read none of them who doubted even slightly about the author of these little works.
Their agreement, which Dionysius the Carthusian in his preface to our author calls the common agreement of all, is clear from the fact that Alexander of Hales, in part 2 from question 36; Albert the Great, on book 2 of the Sentences, distinctions 9 and 10; Blessed Thomas, in the first part, question 108, and everywhere; Blessed Bonaventure, on the said distinctions 9 and 10; Durandus, Scotus, Richard, Gabriel, and others in the same place, always called him Dionysius by antonomasia, without any addition. They would not have called him this, nor would they have valued him so highly, if they had regarded him as uncertain, doubtful, or supposititious.
With the same confidence and reverence, Saint Bonaventure, clinging to his imitation and footsteps, composed a learned book On the Ecclesiastical Hierarchy; and Saint Thomas published commentaries on the book On the Divine Names, as also Robert Grosseteste, Bishop of Lincoln, did on the Angelic Hierarchy. Alfonso de Madrigal, Tostado, Bishop of Avila, also held them to be Areopagitic in his commentaries on Joshua, chapter 10, question 88.
I know, Scaliger, that you regard all the Scholastics as masks and dullards, and that you cannot even bear their name. But in this too I see that you are very unlike your father Julius, a most learned man, and one of better judgment than you - pardon the truth - and of more solid talent as well. For he, when he had been a Franciscan, had read and learned those authors, as you admit in his Life; he always valued them very highly, and he seriously affirmed in his Exercitations on Subtlety against Cardano that he preferred their naked and uncultivated wisdom, whom he repeatedly calls, in jest, his Barbarians, to all more elegant literature.
You, enjoy your own lifted eyebrow, and shake away, though you will never shake heaven or earth. In this matter I follow the judgment of your father, and I congratulate myself that I have the Councils, the Fathers, and all the Scholastics, with one exception, as favorable judges in these Vindications.
