Students of later medieval semantics are familiar with the controversy that developed at the end of the thirteenth century over the signification of names. The debate focused on the signification of common nouns such as ‘man’ and ‘animal’: Do they signify an extramental thing or a mental representation of an extramental thing?Some authors at the end of the thirteenth century also discussed another question concerning what names signify, that is, whether they signify the composite of matter and form or only (...) the form of the composite. This second debate will not be considered in this article. Duns Scotus is commonly recognized as having played an important role in this debate.See Costantino Marmo, “Ontology and Semantics in the Logic of Duns Scotus,” in Umberto Eco and Costantino Marmo, ed., On Medieval Theory of Signs, (Amsterdam and Philadelphia: John Benjamins, 1989), pp. 161–63; and esp. Dominik Perler, “Duns Scotus on Signification,” Medieval Philosophy and Theology 3 (1993): 97–120. On the topic in general, see Paul Vincent Spade, “The Semantics of Terms,” in N. Kretzmann, A. Kenny, J. Pinborg, eds., The Cambridge History of Later Medieval Philosophy (Cambridge: Cambridge U.P., 1982), pp. 188–90; Jan Pinborg, “Bezeichnung in der Logik des XIII. Jahrhunderts,” in Albert Zimmermann, ed., Der Begriff der Repraesentatio im Mittelalter, Miscellanea Mediaevalia 8 (Berlin and New York: de Gruyter, 1971): 238–81; Elizabeth J. Ashworth, “Signification and Modes of Signifying in Thirteenth-Century Logic: A Preface to Aquinas on Analogy,” Medieval Philosophy and Theology 1 (1991): 43–53; Claude Panaccio, “From Mental Word to Mental Language,” Philosophical Topics 20 (1992): 125–47. In his Ordinatio, he alludes to a magna altercatio among his contemporaries concerning signification.John Duns Scotus, Ordinatio 1.27.1–3 n.83, in Commissio Scotistica, ed, Opera omnia 6 (Vatican City: Typis Polyglottis, 1963), p. 97. What is more, he gives, in his two commentaries on Aristotle’s Peri hermeneias, a detailed and fair analysis of the two contrasting positions on this issue.John Duns Scotus, Super Peri hermeneias 1.2, and Super Peri hermeneias 2.1, in Opera omnia 1 (Paris: L. Vivès, 1891), pp. 540–44, 582–85. Scotus’s logical commentaries are usually thought to have been composed before his theological writings, in the last decade of the thirteenth century. (shrink)

In some passages Scotus seems to endorse a thoroughgoing voluntarism, holding not merely that the moral law is established entirely by God's will, but even that there is no reason why God wills in one way rather than another. In other passages, however, Scotus insists that reason plays an important role in morality—that right reason is an essential element in the moral goodness of an action, and that moral truth is accessible to natural reason. -/- Many commentators have supposed that (...) these two views are incompatible, and so they have seen only three options for interpreting Scotus: (i) one can simply concede that Scotus is inconsistent, (ii) one can deny that Scotus in fact allows reason a place in morality, or (iii) one can deny that Scotus is really a thoroughgoing voluntarist. We can find all three of these views in print. By laying out Scotus's view of the role of reason in morality and showing how it coheres with his voluntarism, I show that there is in fact no difficulty here. (shrink)
