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)

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)

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.

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.

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.

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)

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.

Like any other group of philosophers, scholastic thinkers from the Middle Ages disagreed about even the most fundamental of concepts. With their characteristic style of rigorous semantic and logical analysis, they produced a wide variety of diverse theories about a huge number of topics. The Routledge Companion to Medieval Philosophy offers readers an outstanding survey of many of these diverse theories, on a wide array of subjects. Its 35 chapters, all written exclusively for this Companion by leading international scholars, are (...) organized into seven parts: I Language and Logic II Metaphysics III Cosmology and Physics IV Psychology V Cognition VI Ethics and Moral Philosophy VII Political Philosophy In addition to shedding new light on the most well-known philosophical debates and problems of the medieval era, the Companion brings to the fore topics that may not traditionally be associated with scholastic philosophy, but were in fact a veritable part of the tradition. These include chapters covering scholastic theories about propositions, atomism, consciousness, and democracy and representation. The Routledge Companion to Medieval Philosophy is a helpful, comprehensive introduction to the field for undergraduate students and other newcomers as well as a unique and valuable resource for researchers in all areas of philosophy.

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.’.

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)

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)

The chapter shows that Scotus defends the view that ‘God exists’ is both metaphysically and logically necessary. Thus, Scotus maintains that denying that God exists involves asserting a contradiction, and that this can be shown to be the case. But while Scotus believes that it can be shown that there is a concept in virtue of which ‘God exists’ is self-evident, he also believes that human beings in the current run of things can have no access to the content of (...) this concept. The chapter also relates the claims that God is both metaphysically and logically necessary to the kind of causally dependent modalities that Scotus employs in his attempt to prove God’s existence. (shrink)

Scotus holds that dispositional and occurrent cognitions (intelligible species and acts of cognition, in the medieval jargon) are qualities that inhere in the soul. These qualities have semantic or conceptual content. I show that such content is nothing in any sense real, and that this content consists either in the relevant quality’s being (factually) measured by an extramental object, or in its being such that it would be measured (counterfactually) by such an object in the case that there were such (...) an object. The measurement relation, in the case of an intelligible species, is secured by the species’s internal structure; in the case of an act of cognition, it is secured either by some sort of (non-causal) relation to a species, or by a (non-causal) relation to an external object.

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)

Duns Scotus defends the view that we can speak univocally of God and creatures. When we do so, we use words in the same sense in the two cases. Scotus maintains that the concepts that these univocal words signify are themselves univocal: the same concept in the two cases. In this paper, I consider a related question: does Duns Scotus have the notion of analogous concepts—concepts whose relation to each other lies somewhere between the univocal and the equivocal? Using some (...) neglected texts from Scotus’s attempt to refute Henry of Ghent’s rejection of univocity, I argue that he does, and that he uses his account of univocity to ground the relation of analogy between two concepts. According to Scotus, analogous concepts are compositional, and overlap at a univocal concept. (shrink)

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

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)

Duns Scotus (c. 1266-1308) has long ranked as one of the most challenging of philosophers. He was known from shortly after his death as doctor subtilis—the subtle doctor—and his obscure style and complex thought-processes make him a hard thinker to study. That said, he quickly established an almost cult following among his students, and his thought, for all its density, remained hugely popular throughout the Middle Ages and beyond. It is no exaggeration to claim that the last two decades have (...) seen a remarkable burgeoning of Duns Scotus studies—perhaps not one of medieval proportions, but certainly noticeable. There are various reasons for this, some obvious, some not so obvious, and I will begin by considering .. (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)

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)

This paper discusses two interrelated questions about ontological commitment in the thought of Gregory of Rimini (d. 1358), questions having to do with both hylomorphic composites of matter and substantial form, and with complexe significabilia that typically obtain in cases of substance–accident composition. The first question is that of the existence of real relations: neither hylomorphic composites nor complexe significabilia require real relations tying their various co-located components together. The second is that of the reducibility of such wholes to the (...) sum of their parts: neither hylomorphic composites nor complexe significabilia are anything other than their co-located parts. And all such items can be disunited merely by a divine volition, requiring nothing extramental added to the ontology, and no change in position. (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)

According to Swinburne, one way of dealing with the guilt that attaches to a morally bad action is satisfaction, consisting of repentance, apology, reparation, and penance. Thus, Christ's life and death make atonement for human sin by providing a reparation which human beings would otherwise be unable to pay. I argue that the nature of God's creative activity entails that human beings can by themselves make reparation for their sins, merely by apology. So there is no need for additional reparation, (...) and the satisfaction theory of the atonement is otiose. Following an insight of Swinburne's, I argue that satisfaction is not sufficient for forgiveness, since satisfaction does not place the wronged party under any obligation to forgive the wrongdoer. Christ's death merits the forgiveness of those sins for which human beings have made satisfaction. It does this in virtue of a divine promise to reward Christ's meritorious life with the forgiveness of such human sin. (shrink)

According to Henry of Ghent (d. 1293), it is impossible for the second person of the Trinity to assume into unity of person an irrational nature (e.g., a stone nature), or to assume a rational nature that does not enjoy the beatific vision. He argues that the assumption of a nature to a divine person entails both that the nature has the sort of powers that could exercise supernatural activities and that these powers are exercised. Henry’s Franciscan opponents argue against (...) this. Existent irrational natures (like existent rational natures) are not necessarily subsistent and belonging to a kind does not require the opportunity to exercise the causal powers associated with that kind.

This chapter contains sections titled: Metaphysics and epistemology.

This chapter highlights a well-known problem for defenders of transubstantiation: namely, the apparent impossibility of supposing that accidents can be separated from their substance. It begins by arguing that Aquinas’s account of accidents, in which the truth-making function of accidents relative to their substances is understood in terms of the existence of such accidents, is highly susceptible to this kind of objection. The next section considers Giles of Rome’s attempts to overcome this worry, most specifically by distinguishing the existence of (...) an accident from its truth-making function, both of which are described. Giles maintains that the existence of an accident is to be identified with the existence of its substance. According to Scotus, this means that Giles is scarcely better off than Aquinas in defending himself against the worry about separated accidents, since a separated accident needs its own existence and, Scotus avers, there is no way for an accident to gain existence when separated. Scotus agrees with Giles that the truth-making function of accidents is to be distinguished from their existence, and holds that accidents, even when united to their substances, have their own proper existence. Overall, the tale is one of the increasing hypostatization of accidents in the light of pressures from Eucharistic doctrine. (shrink)

Giles of Rome systematically distinguishes two kinds of modes, which in this essay are labelled ‘conjunction modes’ and ‘category modes’. The latter - according to which a substance might have the mode of an accident, and an accident the mode of a substance - are ontologically innocent, and predications about them are parasitic on conjunction modes. Conjunction modes are features of the universe, and are deposited in their subjects by things united to but really distinct from their subjects. For example, (...) a quantity-thing, united to a substance, deposits a quantity-mode in the substance; and an existence-thing, united to a particular essence, deposits an existence-mode in the essence. In this essay, some attempt is made to defend this view against objections raised by Ockham. (shrink)

[Marilyn McCord Adams] In this paper I begin with Aristotle's Categories and with his apparent forwarding of primary substances as metaphysically special because somehow fundamental. I then consider how medieval reflection on Aristotelian change led medieval Aristotelians to analyses of primary substances that called into question how and whether they are metaphysically special. Next, I turn to a parallel issue about supposits, which Boethius seems in effect to identify with primary substances, and how theological cases-the doctrines of the Trinity, the (...) Incarnation, and of the human soul's separate survival between death and resurrection-call into question how and to what extent supposits are metaphysically special. I conclude with some reflections on various senses of being metaphysically special and how they pertain to primary substances and supposits. /// [Richard Cross] Scotus's belief that any created substance can depend on the divine essence and/or divine persons as a subject requires him to abandon the plausible Aristotelian principle that there is no merely relational change. I argue that Scotus's various counterexamples to the principle can be rebutted. For reasons related to those that arise in Scotus's failed attempt to refute the principle, the principle also entails that properties cannot be universals. (shrink)
