This book is a philosophical analysis of Plotinus' views on sense-perception. It aims to show how his thoughts were both original and a development of the ideas of his predecessors, in particular those of Plato, Aristotle and the Peripatetics. Special attention is paid to Plotinus' dualism with respect to soul and body and its implications for his views on the senses. The author combines a historical approach to his subject, setting Plotinus' thought in the context of thinkers who preceded and (...) succeeded him, with a proper analysis of his ideas and, where appropriate, of those from which they derived.

Plotinus was the founder of Neoplatonism, whose thought has had a profound influence on medieval philosophy, and on Western philosophy more broadly. In this engaging book, Eyjólfur K. Emilsson introduces and explains the full spectrum of Plotinus’ philosophy for those coming to his work for the first time. Beginning with a chapter-length overview of Plotinus’ life and works which also assesses the Platonic, Aristotelian and Stoic traditions that influenced him, Emilsson goes on to address key topics including: Plotinus’ (...) originality the status of souls Plotinus’ language the notion of the One or the Good Intellect, including Plotinus’ holism the physical world the soul and the body, including emotions and the self Plotinus’ ethics Plotinus’ influence and legacy. Including a chronology, glossary of terms and suggestions for further reading, _Plotinus _is an ideal introduction to this major figure in Western philosophy, and is essential reading for students of ancient philosophy and classics.

Review of Eyjólfur Kjalar Emilsson, Plotinus on Intellect, Clarendon Press, Oxford, 2007.

Plus que tout autre philosophe antique, Plotin semble mettre ses interprètes au défi de décrypter le fond de sa pensée. En effet, elle a l’air d’un système, mais le lecteur des Ennéades ne se voit pas livrer les structures conceptuelles principales qui doivent en assurer la cohérence. Emilsson s’est proposé le décryptage de certaines structures qui ont la fonction de principe conceptuel soit tout à fait général soit spécifique pour un champ thématique déterminé. Après avoir proposé une étude...

Plotinus (205-269 AD) led the philosophical movement of Neoplatonism, which reinterpreted Plato's thought later in antiquity and went on to become a dominant force in the history of ideas. Emilsson's in-depth study of Plotinus' central doctrine of Intellect caters for the increasing interest in Plotinus with philosophical clarity and rigor.

Ennead VI.4-5, originally written as a single treatise, contains Plotinus' most general and sustained exposition of the relationship between the intelligible and the sensible realms, addressing and coalescing two central issues in Platonism: the nature of the soul-body relationship and the nature of participation. Its main question is, How can soul animate bodies without sharing their extension? The treatise seems to have had considerable impact: it is much reflected in Porphyry's important work, Sententiae, and the doctrine of reception according to (...) the capacity of the recipient, for which this treatise is the main source, resonated in medieval thinkers.

Oxford Studies in Ancient Philosophy is a volume of original articles on all aspects of ancient philosophy. The articles may be of substantial length, and include critical notices of major books. OSAP is now published twice yearly, in both hardback and paperback.

How should I live? How can I be happy? What is happiness, really? These are perennial questions, which in recent times have become the subject of diverse kinds of academic research. Ancient philosophers placed happiness at the centre of their thought, and we can trace the topic through nearly a millennium. While the centrality of the notion of happiness in ancient ethics is well known, this book is unique in that it focuses directly on this notion, as it appears in (...) the ancient texts. Fourteen papers by an international team of scholars map the various approaches and conceptions found from the Presocratics through Plato, Aristotle, and Hellenistic philosophy, to the Neoplatonists and Augustine in late antiquity. They address questions raised by ancient thinkers that are still of deep concern today. (shrink)

The late ancient commentators on Aristotle, most of them Platonists, have been gradually re-emerging on the philosophical and scholarly horizon during the last two or three decades. Their reappearance is not likely to cause any major transformations of the scene, but they are interesting enough in themselves to deserve careful study and they have been influential in the past to the extent that proper understanding of their work sheds light on the subsequent history of the interpretation of Aristotle. This and (...) much more is borne out by Blumenthal's excellent study. A considerable number of ancient commentaries have now appeared in English translations initiated by Richard Sorabji, and books and articles on them have begun to appear as never before. After writing some pioneering works on Plotinus's psychology, in which the relevance of Aristotle for the latter's fundamentally Platonic psychology is much in focus, Blumenthal set out in the 1970s to study the commentators and thus belongs to the pioneers in the contemporary awakening.

The thesis is a philosophical and historical study of Plotinus' views on sense-perception. Chapter I contains an exposition of Plotinus' metaphysics. Chapter II deals with Plotinus' views on man and the soul in general. In Chapter III Plotinus' views on visual transmission are discussed. It is argued that his doctrine of visual transmission, which Plotinus describes in terms of sympatheia, is to be regarded as a synthesis of Platonic, Aristotelian and Stoic elements. Like other ancient philosophers Plotinus holds that sense-perception (...) involves an affection of the percipient. In Chapter IV his notion of affection in sense-perception is examined. It is argued that what Plotinus calls affections in this context are sensations, and differences between Plotinus' and certain modern views of sensations are pointed out. Plotinus has original views on the unity of the senses. In Chapter V these views, which Plotinus expresses in terms of the omnipresence of the soul as a whole in the body, are discussed and explained. It is also argued that though original Plotinus' position is to be seen as a development of views expressed by Plato and Aristotle, and in particular by Alexander of Aphrodisias. Plotinus' views on the objects of perception are a matter of debate. In Chapter VI it is argued that despite contrary appearances Plotinus consistently holds that the objects of sense-perception are external things. Chapter VI also contains an examination of Plotinus' notion of perceptions as judgements. Chapter VII deals with the notion of forms in Plotinus' theory of perception. Plotinus' view that the soul is active in perception is explained. It is suggested that in Plotinus' view the forms we are supposed to entertain when we perceive are developed from innate "unfolded forms", and that perceptual judgements are to be identified with the entertaining of forms. In the Appendix Plotinus' position on the mind-body relationship is discussed. It is argued that he rejects materialsm for interesting and original reasons. (shrink)

This is an introduction to the philosophy of Plotinus, with five chapters bearing the titles "Form," "Light," "Silence," "Word," and "Love." It contains a bibliography, an index of Plotinian passages referred to, and a general index.

Platonism and Christian Thought in Late Antiquity examines the various ways in which Christian intellectuals engaged with Platonism both as pagan competitors and as a source of philosophical material useful to the Christian faith. The chapters are united in their goal to explore transformations that took place in the reception and interaction process between Platonism and Christianity in this period. The contributions in this volume explore the reception of Platonic material in Christian thought, showing that the transmission of cultural content (...) is always mediated, and ought to be studied as a transformative process by way of selection and interpretation. Some chapters also deal with various aspects of the wider discussion on how Platonic, and Hellenic, philosophy and early Christian thought related to each other, examining the differences and common ground between these traditions. Platonism and Christian Thought in Late Antiquity offers an insightful and broad ranging study on the subject, which will be of interest to students of both philosophy and theology in the Late Antique period, as well as anyone working on the reception and history of Platonic thought, and the development of Christian thought. uity offers an insightful and broad ranging study on the subject, which will be of interest to students of both philosophy and theology in the Late Antique period, as well as anyone working on the reception and history of Platonic thought, and the development of Christian thought.

In this article I wish to re-examine the vexed issue of the possibility of idealism in ancient and medieval philosophy with particular reference to the case of Johannes Scottus Eriugena (c. 800–c. 877), the Irish Neoplatonic Christian philosopher. Both Bernard Williams and Myles Burnyeat have argued that idealism never emerged (and for Burnyeat, could not have emerged) as a genuine philosophical position in antiquity, a claim that has had wide currency in recent years, and now constitutes something of an orthodoxy.1. (...) Myles Burnyeat, “Idealism and Greek Philosophy: What Descartes Saw and Berkeley Missed,” Philosophical Review 91 (1982): 3–40, repr. in Godfrey Vesey, ed., Idealism—Past and Present (Cambridge: Cambridge U.P., 1982), pp. 19–50. Hereafter this essay will be cited in the version printed in Vesey, ed. Richard Sorabji (instancing Gregory of Nyssa) and Werner Beierwaltes (citing Proclus and Eriugena), and Eyjólfur Kjalar Emilsson (discussing Plotinus), on the other hand, have all argued that idealism is to be found in the Neoplatonic tradition, a tradition neglected by Burnyeat.Richard Sorabji, “Gregory of Nyssa: The Origins of Idealism,” in Time, Creation and Continuum. Theories in Antiquity and the Early Middle Ages (London: Duckworth, 1983), pp. 287–96; Werner Beierwaltes, Denken des Einen. Studien zur neuplatonischen Philosophie and ihrer Wirkungsgeschichte (Frankfurt: Klostermann, 1985). See also Beierwaltes, “Die Wiederentdeckung des Eriugena im Deutschen Idealismus,” in Platonismus und Idealismus (Frankfurt: Klostermann, 1972), pp. 188–201, and his “Zur Wirkungsgeschichte Eriugenas im Deutschen Idealismus und danach. Eine kurze, unsystematische Nachlese,” in Eriugena. Grundzüge seines Denkens (Frankfurt: Klostermann, 1994), pp. 313–330. Eyjólfur Kjalar Emilsson, “Cognition and its Object,” in Lloyd P. Gerson, ed., The Cambridge Companion to Plotinus (Cambridge: Cambridge U.P., 1996), pp. 217–49, esp. pp. 245–49. But see, Lloyd P. Gerson, Plotinus (London: Routledge, 1994), p. 227, n.3, who maintains that Plotinus is not an idealist. Similarly, in a 1989 study, I argued not only that idealism was a genuine possibility in late classical and in medieval philosophy, but that that the ninth-century Carolingian philosopher Johannes Eriugena presents a striking example of an extremely radical, almost fantastical, idealism.Dermot Moran, The Philosophy of John Scottus Eriugena. A Study of Idealism in the Middle Ages (Cambridge: Cambridge U.P., 1989). Of course, the whole discussion depends entirely on what is meant by ‘idealism’. Burnyeat uses Berkeley’s immaterialism as his standard for idealism, and it is this decision, coupled with his failure to acknowledge the legacy of German idealism, which prevents him from seeing the classical and medieval roots of idealism more broadly understood.

The “Slicing Problem” is a thought experiment that raises questions for substrate-neutral computational theories of consciousness, including those that specify a certain causal structure for the computation like Integrated Information Theory. The thought experiment uses water-based logic gates to construct a computer in a way that permits cleanly slicing each gate and connection in half, creating two identical computers each instantiating the same computation. The slicing can be reversed and repeated via an on/off switch, without changing the amount of matter (...) in the system. The question is what do different computational theories of consciousness believe is happening to the number and nature of individual conscious units as this switch is toggled. Under a token interpretation, there are now two discrete conscious entities; under a type interpretation, there may remain only one. Both interpretations lead to different implications depending on the adopted theoretical stance. Any route taken either allows mechanisms for “consciousness-multiplying exploits” or requires ambiguous boundaries between conscious entities, raising philosophical and ethical questions for theorists to consider. We discuss resolutions under different theories of consciousness for those unwilling to accept consciousness-multiplying exploits. In particular, we specify three features that may help promising physicalist theories to navigate such thought experiments. (shrink)

This article is a discussion of E. K. Emilsson, Plotinus (London and New York, 2017). Three themes are selected: causation; the holistic account of intelligible being; the status of matter and body. The discussion ends with some remarks about Emilsson’s approach to Plotinus’ philosophy. Emilsson’s account of Plotinus’ causation is based on the transmission model, what Emilsson calls ‘the principle of prior possession’. Here it is argued that the transmission model requires qualifications in order to be (...) applied to Plotinus’ account of causation. The section on Plotinus’ holism focuses on two analogies: that of science and its theorems and that of craftsmanship. The section on matter and body addresses the issue of Plotinus’ dualism as different from Cartesian dualism. The final remarks assess Emilsson’s philosophical approach to Plotinus, his use of contemporary philosophical notions, and the problem of Plotinus’ philosophical mysticism. (shrink)

It is commonly assumed that Kant is indebted to Aristotle not to Plato. In this paper we argue, however, that the following four central topics in Kant's philosophy must be recognized as having Platonic roots. 1. The idea that metaphysics is a system of synthetic apriori judgements and the idea that such judgments require pure intuition. 2. The idea that geometrical objects have a certain purposiveness. 3. The notion of dialectic. 4. The notion of ideas and their role in the (...) sphere of cognition and morality. (shrink)

This paper discusses the role of innate concepts derived from Intellect in Plotinus’ account of cognition of the sensible realm. Several passages have been claimed as evidence for such innateness, but an analysis of them shows that they do not support this claim. It is tentatively suggested that, nevertheless, some very general concepts such as difference, sameness and being are integral to the faculty of sense and play a crucial role in concept formation. It is further argued that reasoning about (...) the sensible realm takes place to a large extent without the involvement of the higher realms of Plotinus’ hierarchy of being. Clearly, however, for value concepts such as those of goodness, justice and beauty human beings are dependent upon an illumination from Intellect. (shrink)
