The nature and content of the thought of Duns Scotus (c. 1266-1308) remains largely unknown except by the expert. This book provides an accessible account of Scotus' theology, focusing both on what is distinctive in his thought, and on issues where his insights might prove to be of perennial value.

Richard Cross provides the first full study of Duns Scotus's theory of cognition, examining his account of the processes involved in cognition, from sensation, through intuition and abstraction, to conceptual thought. Cross places Scotus's thought clearly within the context of 13th-century study on the mind, and of his intellectual forebears.

The period from Thomas Aquinas to Duns Scotus is one of the richest in the history of Christian theology. The Metaphysics of the Incarnation aims to provide a thorough examination of the doctrine in this era, making explicit its philosophical and theological foundations. Medieval theologians believed that there were good reasons for supposing that Christ's human nature was an individual. In the light of this, Part 1 discusses how the various thinkers held that an individual nature could be united to (...) a divine person. Part 2 shows how one divine person could be incarnate without any other. Part 3 deals with questions of Christological predication, and Part 4 shows how an individual nature is to be distinguished from a person. The work begins with a full account of the metaphysics presupposed in the medieval accounts, and concludes with observations relating medieval accounts to modern Christology. (shrink)

Duns Scotus, along with Thomas Aquinas and William of Ockham, was one of the three most talented and influential of the medieval schoolmen, and a highly original thinker. This book examines the central concepts in his physics, including matter, space, time, and unity.

Contrary to a common assumption, I argue that there is full agreement between East and West on the issue of the relation between the divine essence and the divine persons. I defend this claim by using the understanding of universals found in D. M. Armstrong to cast light on the theories. Taking Gregory of Nyssa and John of Damascus as representatives of the Eastern tradition, I show that this tradition sees the divine essence as a numerically singular object that is (...) wholly present in each divine person. The Eastern tradition explicitly sees this object as a universal. The Western tradition – exemplified in Augustine and Aquinas – likewise sees the divine essence as a numerically singular object that is wholly present in each divine person. But this tradition customarily denies that such an object could be a universal, on the merely philosophical grounds that universals are divided amongst the particulars that share them, and thus cannot be numerically one. Having shown the fundamental consonance of the two traditions, I argue by way of conclusion that differences between social and non–social theories of the Trinity depend entirely on the nature and extent of the features that are supposed to distinguish the persons from each other.

This chapter contains sections titled: Metaphysics and epistemology.

The Christian doctrine of the Incarnation maintains that the second person of the Trinity became a human being, retaining all attributes necessary for being divine and gaining all attributes necessary for being human. As usually understood, the doctrine involves the claim that the second person of the Trinity is the subject of the attributes of Jesus Christ, the first-century Jew whose deeds are reported in various ways in the New Testament. The fundamental philosophical problem specific to the doctrine is this: (...) how is it that one and the same thing could be both divine and human. Most of the philosophical effort devoted to the specifics of the doctrine has centered on this issue, which is the focus of this article. (shrink)

According to Scotus, an intelligible species with universal content, inherent in the mind, is a partial cause of an occurrent cognition whose immediate object is the self-same species. I attempt to explain how Scotus defends the possibility of this causal activity. Scotus claims, generally, that forms are causes, and that inherence makes no difference to the capacity of a form to cause an effect. He illustrates this by examining a case in which an accident is an instrument of a substance (...) in the production of a certain sort of effect. All that is required is that the accident is relevantly joined to the substance, whether or not it inheres in the substance. Since intelligible species are bearers of semantic content, it follows that non-inherent objects of thought can also be the bearers of such content. Such objects are included in the mind without inherence, and the boundary between the mind and external reality is to this extent broken down. (shrink)

The High Middle Ages were remarkable for their coherent sense of 'Christendom': of people who belonged to a homogeneous Christian society marked by uniform rituals of birth and death and worship. That uniformity, which came under increasing strain as national European characteristics became more pronounced, achieved perhaps its most perfect intellectual expression in the thought of the western Christian thinkers who are sometimes called 'scholastic theologians'. This book offers the first focused introduction to these thinkers based on the individuals themselves (...) and their central preoccupations. (shrink)

Aquinas distinguishes four types of part included in a hypostasis (’suppositum’): (1) kind-nature; (2) individuating feature(s); (3) accidents; (4) concrete parts. (1) - (3) in some sense contribute ’esse’ to the ’suppositum’. Usually Aquinas holds that Christ’s human nature does not contribute ’esse’ to its divine ’suppositum’, since it is analogous to a concrete part of its ’suppositum’. This effectively commits Aquinas to the Monophysite heresy. In ’De Unione’ Aquinas argues instead that Christ’s human nature contributes ’secondary ’esse‘ to its (...) divine ’suppositum’. This account is coherent and orthodox, but sacrifices explanatory power. (shrink)

This article highlights five areas of Scotus' philosophy that have recently been the subject of scholarly discussion. (1) Metaphysics : I outline the most current accounts of Scotus on individuation (thisness or haecceity) and the common nature. (2) Modal theory : I consider recent accounts both of Scotus' innovations in spelling out the notion of the logically (and broadly logically) possible, and of his account of the independence of modality. (3) Cognitive psychology : I examine recent views of Scotus' theory (...) of intentionality and the nature of mental content. (4) Semantics : I look at contemporary expositions of Scotus' view that words signify things. (5) Metaethics and ethics : I briefly describe conflicting interpretations of Scotus' metaethics, and discuss whether Scotus should be thought of as adopting some kind of divine-command theory or not. I note too Scotus' claim that virtues and passions can be located in the will. (shrink)

Dopo una premessa in cui si precisano le finalità dell'articolo e si fa il punto sugli antecedenti della discussione, concentrandosi sulle trattazioni teologiche degli autori del sec. XII, l'A. studia gli sviluppi offerti da Enrico di Gand alla teoria agostiniana delle relazioni applicata alle tre persone della Trinità. La seconda parte dello studio è dedicata alla risposta elaborata da Duns Scoto alla posizione di Enrico: fondandosi su differenti elaborazioni della teoria della relazione , i due autori analizzzano le proprietà delle (...) tre persone della Trinità, da cui risultano concezioni metafisiche pronfondamente distinte.

According to an important set of medieval arguments, it is impossible to make a distinction between creation and conservation on the assumption of a beginningless universe. The argument is that, on such an assumption, either God is never causally sufficient for the existence of the universe, or, if He is at one time causally sufficient for the existence of the universe, He is at all times causally sufficient for the universe, and occasionalism is true. I defend the claim that these (...) arguments are successful. Since Christian theology requires a distinction between creation and conservation, arguments in favour of the possible eternity of the world fail. (shrink)

John Duns Scotus was the philosopher's theologian par excellence, a man who was interested in arguments for their own sake. Richard Cross explores the theological world in which he lived and his painstaking understanding of the mystery of God.

Upholding a univocity theory of religious language does not entail idolatry, because nothing about univocity entails misidentifying God altogether—which is what idolatry amounts to. Upholders and opponents of univocity can agree on the object to which they are ascribing various attributes, even if they do not agree on the attributes themselves. Neither does the defender of univocity have to maintain that there is anything real really shared by God and creatures. Furthermore, even if much of language is analogous, syllogistic argument—and (...) hence theology’s scientific status, as accepted by the scholastics—requires univocity. (shrink)

Contrary to the claims of recent commentators, I argue that Boethius holds a modified version of the Ammonian three-fold universal (transcendent, immanent, and conceptual). He probably identifies transcendent universals as divine ideas, and accepts too forms immanent in corporeal particulars, most likely construing these along the Aphrodisian lines that he hints at in a well-known passage from his second commentary on Porphyry's Isagoge. Boethius never states the theory of the three-fold form outright, but I attempt to show that this theory (...) nevertheless underlies and gives structure to what Boethius has to say on the topic.

I argue that, if it is thought desirable to avoid the collapse of disability into generic social disadvantage, it is necessary to draw a distinction between impairment (a bodily configuration) and disability (the way in which the environment prevents someone with an impairment from undertaking certain kinds of activities), as in social models of disability. I show how to draw such a distinction by utilizing a distinction between intrinsic and extrinsic properties. I argue further that, using this distinction, it is (...) possible to define ‘impairment’ in ways that do not appeal to notions of the normal, and to define ‘disability’ in terms of ‘impairment.’.

When presenting one of a sequence of theories on individuation, Duns Scotus argues for a formal distinction in creatures between an individual essence and its existence. His reason is that, otherwise, an individual creature would be a necessary existent. Since Scotus maintains that essence is potential to existence, this paper shows how this discussion relates to his exhaustive analysis of actuality and metaphysical potency in the questions on the Metaphysics, book IX, qq. 1–2, concluding that Scotus’s views on essence and (...) existence do not commit him to a realm of real but unactualized possibilia. The paper tentatively suggests that existence, in creatures, consists in a relation to an efficient cause or causes. Scotus holds that God’s existence, identical with his essence, is nevertheless formally distinct from God, since essence/existence and the divine attributes are formally distinct from each other and all included in God.

In lieu of an abstract, here is a brief excerpt of the content:Four-Dimensionalism and Identity Across Time: Henry of Ghent vs. BonaventureRichard CrossModern accounts of the identity of an object across time tend to fall roughly into two basic types.Let us say that something persists ıff, somehow or other, it exists at various times; this is the neutral word. Something perdures iff it persists by having different temporal parts, or stages, at different times, though no one part of it is (...) wholly present at more than one time; whereas it endures iff it persists by being wholly present at more than one time.1On the first of these analyses, but not the second, a persistent object includes temporal parts, and persistent material substances are thus on this analysis four-dimensional objects. On the first analysis, but not on the second, time-indices are explicable in terms of temporal parts. I shall take this as the basic difference between the two views.2Both views allow us to talk of temporal order and temporal direction. I [End Page 393] shall follow the medievals and talk about succession to capture both of these claims: “The notion of succession formally consists in the notion of ‘before’ and ‘after,’”3 and I take it that talk of “before” and “after” entails both order and direction.4 Medieval accounts of identity across time are, however, in some ways more obscure than the two modern ones just described. The medievals tend to associate all temporal succession with temporal extension: an object x has temporal succession if and only if x is temporally extended (and thus includes temporal parts).5 The medievals also (correctly, I believe) tend to suppose that substances—unlike (say) processes—do not have temporal parts.6 Thus, by the end of the thirteenth century the schoolmen commonly [End Page 394] distinguish permanent objects from successive objects. Permanent objects do not, and successive objects do, have temporal parts.7 Successive objects are processes; the class of permanent objects was generally held to include not only God, but also angels, material substances, and static accidents (i.e., accidents which do not entail any sort of process).8Given these claims, there is a problem to be faced in giving an account of the identity of, say, a material substance across time. But it is not the problem we would face. Our problem, post-Hume, is to explain the relevant (explanatory) continuity requirements for identity across time. The medievals’ problem is rather different. They do not need to specify general continuity requirements, because for them there is a very real sense in which substances—and indeed all permanent objects—lack temporal extension and, therefore, any sort of temporal succession at all. The problem for the medievals is thus to explain how substances can persist at all, rather than exist merely fleetingly.9In what follows, I will examine two thirteenth-century solutions to this problem. The first is a radical one: simply to deny the standard claim that substances lack temporal parts. This view will thus bear some resemblance to what we would label four-dimensionalism. The second solution I will examine represents one of the more successful attempts to defend the standard thirteenth-century line that substances lack temporal parts. This solution goes some way towards allowing succession (and time-indexing) without appealing to temporal parts.To understand the debate, we need to keep in mind that the medievals—following Aristotle—talk of the temporality of an object in terms of its being [End Page 395] measured by time. Confusingly, they might speak of a substance’s being measured in one sort of way, and its accidental properties’ being measured in another. Thus, by the end of the thirteenth century it was often claimed that the duration of a substance is measured not by time but by the aevum—the durational measure of objects lacking temporal parts—while some of a substance’s accidental properties could be measured by time. (I will explain in detail below how time and the aevum were understood.) On this view, the temporality of an object’s properties is not sufficient cause for positing the temporality of the object. There are acceptable and unacceptable ways of understanding... (shrink)

Gregory of Rimini (1300s motivations for accepting this view, and indeed how precisely he understands it.

Scotus consistently holds that eternity is to be understood as timelessness. In his early Lectura, he criticizes Aquinas’ account of eternity on the grounds that (1) it entails collapsing past and future into the present, and (2) it entails a B-theory of time, according to which past, present and future are all ontologically on a par with each other. Scotus later comes to accept something like Aquinas’ account of God’s timelessness and the B-theory of time which it entails. Scotus also (...) offers a refutation of his earlier argument that Aquinas’ account of eternity entails collapsing past and future into the present. (shrink)

According to a well-known interpretation, Henry of Ghent holds that possible but non-existent essences – items merely with what Henry labels ‘ esse essentiae ’ – have some reality external to the divine mind, but short of actual existence ( esse existentiae ). I argue that this reading of Henry is mistaken. Furthermore, Henry identifies any essence, considered independently of its existence as a universal concept or as instantiated in a particular as an item that has some kind of reality (...) in the divine intellect, and that constitutes an object of thought for that intellect. This object is distinguished from the universal concepts of creaturely cognition. (shrink)
