Plotinus

Paper draft on the concept of participation in the Late Antique thought of Plotinus and Dionysius the Areopagite.

In Plotinus' Philosophical system of the world we can see three hypostases which result from each other vertically. They include: the One, the intellect, and the soul.There are various views concerning the genesis of the world, such as the theory of creation, which is suggested by holy books, the theory of theophany and manifestation, which belongs to gnostics, and the theory of emanation, in which most philosophers believe.Concerning the genesis of the world, Plotinus believed in emanation. This word is derived (...) from the Latin word "emanatio", meaning eruption from somewhere. According to Plotinus, the One is not the creator of the world so that He could create voluntarily. The world is the overflow of Divine springing. The One cannot create the world according to His free will because creation is a kind of activity, and attributing an act to God disrupts His Stability and is, therefore, a mistake. Thus Plotinus resorted to the metaphor of "emanation". He believed that God does not decrease by being emanated. He tried to follow a middle way between monotheistic creation, on the one hand, and pantheism, on the other. (shrink)

The oneness of being is still one of the most exciting and, at the same time, critical and controversial issues in the field of religious sciences. However, a correct study of it can decrease the number of the involved controversies to some extent. The writer has chosen Plotinus for this study because the Neo-Platonic philosophy, which has Plotinus as its founder, has influenced the thoughts of Muslim thinkers in the fields of gnosis and philosophy. This influence has been exercised through (...) the books Uthulugiya and The Book of Causes. When dealing with the degree that Neo-Platonic philosophy has influenced Islamic philosophy and, particularly, gnosis, some historians in the areas of philosophy and gnosis have gone into such extremes that they have introduced this school as the origin of all the ideas of Islamic thinkers. In this paper, it has been tried to inquire into one of the most important gnostic issues, namely, the oneness of being, from the viewpoints of Plotinus and some Neo-Platonists. It is also intended to clarify whether prominent gnostics, such as Ibn Arabi, and believers in the oneness of being had been influenced by Plotinus, or whether this issue was among the innovations of Muslim gnostics.

The paper follows the development of the concept of transcendence ‹e)pe/keina› from the time when it first entered philosophy in Plato’s The Republic up to Plotinus, who thought it through in all its essential dimensions. In common with some thinkers before him, Plotinus thought of the concept of transcendence in the light of the absolute one Plato analyzed in the first hypothesis of Parmenides. The paper also shows how Plotinus understood transcendence with regard to Being and to thinking. The paper (...) aims to show how Plotinus, by his criticism of the onto-theo-logical structure of philosophical thought, already announced the criticism of traditional philosophy for which Martin Heidegger and Ludwig Wittgenstein became known in the 20th century.

After concluding in the introduction that different things are beautiful in different ways, the first section of the treatise focuses on sensory beauty or beauty of bodies. Rejecting symmetry as a sufficient criterion for beauty, Plotinus explains that things in this world are beautiful to the extent that they participate in form and to the extent that shapeless matter is dominated by shape and the formative principle. Sensory beauty stirs the soul and helps it to recognise and remember transcendental beauty.

According to the history of aesthetics, Plotinus restored the dignity of which Plato’s verdict on artists in The Republic, especially his notorious mirror analogy in the tenth book, had deprived them. The paper analyses the key topics in the first chapter of Plotinus’ treatise On Noetic Beauty : the meaning of arts and their function, the way Plotinus’ aesthetics is firmly embedded in his metaphysics, the defence of imitation/representation of nature and Phidias’ creation of his statue of Zeus at Olympia. (...) It also discusses other authors as possible models for Plotinus. An exploration of inspiration in Phidias opens up questions concerning the role of imagination and the possibilities for symbolism and idealism in art. A comparison of selected passages from Plotinus’ and Plato’s writings shows that there are unexpectedly many points of contact between the two authors and that both explore a range of possibilities from imitation/representation of objects belonging to the visible world, to creation independent of visible models.

Augustine′s conversion to Christianity in A.D. 386 is a pivotal moment not only in his own life, but in Christian and world history, for the theology of Augustine set the course of theological and cultural development in the western Christian church. But to what exactly was Augustine converted? Scholars have long debated whether he really converted to Christianity in 386, whether he was a Platonist, and, if he adhered to both Platonism and Christianity, which dominated his thought. The debate of (...) the last thirteen decades spans an immense body of literature in multiple languages. In this literature, four major views on Augustine′s conversion may be discerned. The first view is associated with Gaston Boissier and Adolph von Harnack, and was famously championed by Prosper Alfaric: that Augustine in 386 converted to neo-Platonism but not to Christianity. Second, there is the view recently promoted by Catherine Conybeare: that Augustine in 386 converted to Christianity and rejected neo-Platonism. Third, there is the view that he converted to Christianity and was also a neo-Platonist; the most famous adherents of this view are Robert J. O′Connell and Pierre Courcelle. Finally, there is the view recently promoted by Carol Harrison: that Augustine committed to Christianity in 386, yet did not utterly reject neo-Platonism; rather, he aimed to develop a Christian faith that was informed by neo-Platonic insight. In this article, I first explain and distinguish these four general views, and then I explain why I prefer the fourth view. -/- More Info: This is the pre-peer reviewed version of Boone, Mark, "The Role of Platonism in Augustine's 386 Conversion to Christianity," Religion Compass 9.5 (May 2015), 151-61.

An exploration of the philosophical and mystical ideas of Plotinus. So as to show that underneath all traditional Western philosophy of being their lies a non-philosophy of 'the one'. The One with whom mystics seek unification or to be united with (also know as realization of the one real self, unity with the Sufi Beloved, buddha-mind, the absolute truth, the foundation or ground of all etc).

Plotinus argues that materialism cannot explain reflexive cognition. He argues that mere bodies cannot engage in the self-reflexive activity of both cognizing some content and being cognitively aware of cognizing this content. Short of outright denying the cognitive unity underlying this phenomenon of self-awareness, materialism is in trouble. However, Plotinus bases his argument on the condition that material bodies are capable of a spatial unity at most, and while this condition has purchase on ancient materialists, it would be rejected today. (...) After considering objections based on our contemporary understanding of a material body, I amend Plotinus' argument to focus instead on the core materialist commitment to external efficient-causal relations. This amended argument regains its urgency for materialism, while retaining the spirit of Plotinus' view. (shrink)

In one of the most famous but equally obscure passages in the Timaeus, Plato describes the generation of time and the heavens. The “moving image of eternity” (37d5) is commonly read as Plato’s most general characterisation of time. Rémi Brague famously challenged the traditional interpretation on linguistic grounds by claiming that Plato actually did not conceive of time as an image (εἰκών) but rather as a number (ἀριθμός). In this paper, I shall claim that this controversy is by no means (...) a modern one. The traditional interpretation is mostly owed to Plato’s most prominent reader, Plotinus, who famously conceives of time in relation to eternity (Enn. III.7.13.24-25). Brague’s alternative reading, however, is anticipated by Simplicius’ attempt to refute the Plotinian interpretation, as I shall show. According to my reconstruction, Simplicius’ reading of the Timaeus not only shows why the traditional interpretation falls short, but it also offers a systematic argument that bolsters Brague’s alternative reading. Finally, I shall show that this is consistent with Plato’s text. It shall become clear that current interpretative problems are essentially prefigured in the late ancient debate. (shrink)

This article focuses on the reception of Aristotle’s Categories by the first three representatives of Greek Neoplatonism: Plotinus (204/205–270 CE), Porphyry (ca. 234–ca. 305 CE), Iamblichus (ca. 242–ca. 325 CE). The first section argues that Plotinus’ acquaintance with Aristotle’s treatises marked a fresh start vis-à-vis the previous Platonist tradition. Aristotle’s views, arguments and vocabulary are ubiquitous in Plotinus writings (the Enneads) and they must be considered an essential part of his philosophical project. Plotinus, however, does not share some of Aristotle’s (...) key theories and is critical of them. The second section focuses on Plotinus’ discussion of Aristotle’s Categories in the tripartite treatise On the Genera of Being (6.1–3). There he rejects the Peripatetic division into ten categories as providing an incomplete account of the genera of being that unduly omits “those which are most authentically beings”, i.e. Plato’s separate Forms. While drawing on earlier Platonist objections to Aristotle, Plotinus’ approach is original insofar as he criticizes Aristotle and his followers not only for omitting intelligible beings in the division of categories, but also for being unable, for this very reason, to work out an adequate division of sensible beings themselves. The third section is devoted to Porphyry, a student of Plotinus’ and the editor of his works. Porphyry worked intensively on Aristotle’s Categories, which he regarded as an introduction not only to logic, but to philosophy as a whole. Unlike Plotinus, Porphyry aimed to integrate Aristotle into Platonism and his engagement with the Categories was a key part of his project after Plotinus’ in-depth criticism. Porphyry’s approach is connected to his view of the subject-matter of the Categories, which he sees as focusing on words insofar as they signify beings, and not on beings as such. The fourth section focuses on some parallels between Plotinus’ Genera of Beings and Porphyry’s works, which may reflect the debate within Plotinus’ school. The fifth section focuses on Iamblichus of Chalcis. Both in theology and in the interpretation of Aristotle’s Categories, Iamblichus aimed to both continue and supplant Porphyry’s work. While Plotinus criticizes Aristotle’s categories for omitting intelligible beings, and while Porphyry accepts Aristotle’s categories insofar as they focus on words signifying sensible things, Iamblichus incorporates his Neoplatonist and Pythagorizing metaphysics into the interpretation of the Categories.

With both the Roman Empire and contemporary scholarship as backdrop, this book contrasts the Imperial Platonism of Plotinus with Plato's own by distinguishing one as a master enlightening disciples, and the other as an Athenian teacher who taught students to discover the truth for themselves in the Academy.

Les lectures plotinienne et proclusienne de Métaphysique Λ ne se résolvent pas dans ces résultats doctrinaux que sont la hiérarchisation de l’Intellect et de l’Un-Bien et l’harmonisation des causalités efficiente et finale. Pour les saisir tant dans leur différence que dans celle qui les oppose toutes deux aux lectures concordistes, il faut déplacer l’analyse du plan des doctrines à celui des concepts. Plus précisément, il faut demander comment Plotin et Proclus intègrent le concept qui, en Métaphysique Λ, condense la charge (...) polémique portée par Aristote contre Platon, à savoir le concept d’energeia. Ce dernier engage en effet une conception radicalement antiplatonicienne du principe premier, dont on montre qu’elle s’articule en quatre critiques fondamentales. On analyse dès lors les stratégies de lecture de Λ mises en oeuvre par Plotin et Proclus de façon à évaluer les angles de contreattaque qu’elles déterminent. Plutôt qu’à une harmonisation ou à une simple hiérarchisation, on a affaire, dans les deux cas quoique sous des modalités différentes, à une intégration dialectique qui en passe par la neutralisation de la charge polémique du concept d’energeia ainsi que par sa réélaboration, elle-même solidaire de modèles causaux distincts tant de celui de Platon que de celui d’Aristote.

In this paper, particular key aspects of the philosophies of Plotinus and Wang Yangming have been analysed comparatively on the basis of important passages of their works. The method used for this investigation can be defined as that of transversal comparative induction, in which the focus is more on working out the details of affinities and similarities. As this means a first step in an encompassing systematic context, differences will be introduced more briefly. The present investigation aims to provide a (...) foundation for a more differentiating and therefore complementing second part, which will consider other contents and topics in both philosophies. The present analysis is performed in three systematic steps and with regard to three basic philosophical ideas: (1) the idea that human consciousness is a central medium in the universal process and interrelatedness of (biological) life as a whole; (2) the idea that the self-unfoldment of reality represents a meta-cognitive process beyond the limits of subjectivity and finite consciousness; and (3) the idea that it is our major task to perfect and know ourselves by means of a “return” to the highest underlying foundation of this universal process. In their own ways, Plotinus and Wang Yangming both show that by enfolding human reflexivity toward the ineffable source of all reality in thought, feeling, human activity, and natural processes, namely by actively pursuing the path of moral and intellective perfection, we become fulfilled mediators of a universal process and of that which all of it represents.

Review of A.A. Long's translation and commentary of Plotinus's "On Matter" (II.4).

Alors que l’éducation apparaît comme un thème principal de la pensée néoplatonicienne, et qu’elle a fait l’objet de nombreux articles scientifiques et chapitres de livres, il n’existe que très peu de monographies sur cette question (on songe par exemple à l’ouvrage d’E. Watts, 2006, City and School in Late Antique Athens and Alexandria, University of California Press, qui a déjà une quinzaine d’années). La contribution de Jean-Michel Charrue, parce qu’elle place l’éducation, même disséminée d...

This chapter focuses on Plotinus’ engagement with Aristotle’s hylomorphism against the wider background of Plotinus’ account of living beings. Plotinus’ general point throughout his writings is that, whatever one might think of the soul as an enmattered form, its status is not sufficiently distinct from that of the body and of its attributes. So Aristotle cannot ground his own distinction between body and soul, since the soul is an attribute among others and all attempts to make sense of its status (...) and of its causal role are doomed to fail. This chapter outlines Plotinus’ critical approach to Aristotle’s hylomorphism from the early treatise 4.7 through the treatises on the soul (4.3 and 4.4) down to the treatises 6.7 and 6.3, where Plotinus develops his own sophisticated theory of incorporeal forms. Particular attention is paid to the status of living bodies within Plotinus’ account of causation. (shrink)

In his Confessions, Augustine says that he achieved great intellectual insight from what he cryptically calls the “books of the Platonists.” Prior to reading these books, he was a corporealist and was unable to conceive of incorporeal beings. Because of the insurmountable philosophical problems corporealism caused for the Christian belief he was seeking, Augustine claims that this was the greatest intellectual barrier he faced in converting to Christianity. As such, the specific contents and effects of these Platonist books are of (...) great biographical and philosophical interest. Heretofore, the explanation of the contents and effects of these books has not been forthcoming. This essay aims to supply it. I argue that Augustine learned the mereological distinction between pertensive and entensive presence in the books of the Platonists. This distinction is required for properly conceiving of incorporeal beings. In support of this thesis, I show that Augustine himself says that he learned this very distinction, that the distinction is present in Platonist texts that scholars agree were among “the books of the Platonists,” that the distinction is present in one of Augustine’s earliest works, and that this distinction is uniquely capable of resolving the philosophical difficulties he faced as a corporealist.

Chapter 20 of Plotinus’ treatise VI, 2 [43] has received particular attention because it seems to deal with the Intellect. However, the connection of this chapter with chapter 19 is problematic insofar as the latter deals with the ways in which species are generated by the first genera. Our aim will be to show that chapter 20 can only be understood in the light of the notion of genus. More precisely, Plotinus’ aim in this chapter is to demonstrate the priority (...) of the genus over its species by means of the theory of double activity. In order to demonstrate this point, the notion of Intellect is introduced by Plotinus as a model (παράδειγμα) to conceive this priority. We will study successively these two chapters to justify this point, insisting on the link between them as well as on the reinterpretation of some key Aristotelian concepts. This study also shows that the use of the comparison with science allows Plotinus to justify the primacy of the intelligible totalities that are the Soul and the Intellect as well as the generation of their respective parts, the particular souls and the particular intellects.

In Ennead I.5 Plotinus attempts to navigate a well-trodden path of inquiry by responding directly to a wide spectrum of popular theories on human flourishing, insisting emphatically that well-being belongs to the present moment. One of his central targets is Aristotle, who insisted that well-being be measured by "a complete life" or a life measured by virtue, a modus vivendi sustained via the development of appropriate habits (hexis) and the avoidance of misfortunes. At the same time the Hellenistic schools-with their (...) insistence that happiness is available to practitioners in the immediacy of the "now"-take pride of place in Plotinus' short screed on the subject. This treatment provides an in-depth analysis of Plotinus' unique conception of the value of the present moment by highlighting Plotinus' dialogue with Aristotle and Hellenistic conceptions of the soul, pleasure and pain, and time and eternity.

The analysis of the characteristics of the concept φρόνησις (phronesis) in Plotinus’ philosophy inevitably opens a wider discussion about the status and autonomy of ethical theory in Plotinus’ philosophy and about the relationship between contemplative and active life. On the one hand, the paradigmatic interpretations hold that there is an otherworldly, self-centred and elitist ethics in Plotinus’ philosophy, and on the other, in the recent interpretations, the so-called “ethics of descent”, as opposed to “ethics of ascent”, the autonomy of πρᾶξις (...) is asserted. Without examining φρόνησις with a predefined position about the status of practical ethics in Plotinus, in this article the standpoint on this issue will be formed precisely through an analysis of φρόνησις, as a key axis around which the understanding of practical reasoning and action develops. In this analysis, the connection between φρόνησις and likeness to God, understood as the ultimate goal of life, will be investigated; as well as the relationship between θεωρία and πρᾶξις, considered through the relationship between φρόνησις and σοφία, as well as through the conception of virtue as ἕξις. The goal is to show to what extent φρόνησις, and thus ethical practice, is dependent on contemplation, that is, whether φρόνησις has an autonomous status or performs an intermediary role between the intellect and the human soul.

With his philosophy of transcendence, Karl Jaspers is considered one of the few great metaphysicians of the 20th century. This study is devoted to the roots of his transcendental thinking in the philosophy of Plotinus (c. 204–270). It demonstrates the constitutive role that reference to the philosophia perennis played for Jaspers, as well as his early and intensive engagement with the founder of Neoplatonism, who for Jaspers was ‘the metaphysician par excellence’. His connection with Plotinus opens up fascinating new perspectives (...) on Jaspers’ concept of existential self-emergence as an ascent to the One, and on his henological philosophy of reason and his speculative paradoxical thinking about God.

This book addresses the mid-rank of the soul theme as it emerges in Plotinus and Augustine in the context of their respective interpretations of universal order. They both use the journey metaphor to describe the soul’s progress through the turbulent “sea” of earthly existence.

Anthony A. Long’s recent book, Selfhood and Rationality in Ancient Greek Philosophy: From Heraclitus to Plotinus (2022), is a collection of fourteen essays that explore the themes of selfhood and rationality in ancient Greek philosophy. Long’s book provides an illuminating account of the vast ancient Greek tradition and an engaging tour that begins with pre-Socratic thought and ends with Stoicism and Neoplatonism seeking answers to the multifaceted question of the rational self, its emergence and evolution within Greek antiquity.

The Enneads are our main source for understanding Plotinus' philosophical architecture. In this work, the philosopher attempted to fully explain his own philosophical doctrine. However, there is a treatise in this work that gives the impression of being outside the philosophical architecture. This treatise, entitled Against the Gnostics, serves two different purposes for researchers. First, we have the opportunity to confirm the philosopher's own teaching through this treatise. Second, through Plotinos' objections to the Gnostics, we witness the heated debates of (...) the time. Also, during this discussion we will have the opportunity to get to know the Gnostics from a philosopher's point of view. In this treatise, Plotinus develops a detailed counter-position to the Gnostics and directly refutes them. These are the main lines: The universe is the product of an evil creator and therefore completely evil; renunciation of earthly life with hatred and contempt for it; the doctrine that salvation from the material world can be granted only to a select group by grace. Plotinos developed both a radical rejection of these questions and solutions on how to understand them. In this paper, I would like to review this rejection on a textual basis for the first time.

Marsilio Ficino’s view on ensoulment, which can be extrapolated from his critique of natal astrology, relies on the relations of metaphysical proportion between the different levels of life and being which are central to Platonic philosophy. Drawing primarily on Plotinus, Ficino describes the emergence of life in the embryo as a process in which the World Soul is the true agent. For him, the ‘human nature’ that is present in the developing embryo attracts into the mother’s womb the seed of (...) ‘human nature’ which is present in the World Soul’s vegetative power. Once channelled into the womb, the World Soul’s vegetative power animates the embryo’s body. Now endowed with organic life, the embryo becomes irresistibly attractive to the rational soul, which in this way is drawn down to it and becomes embodied. For Ficino, the moment when ‘rational’ ensoulment happens is completely irrelevant to prefiguring one’s life path, contrary to what was claimed by natal astrology. Nevertheless, it leaves an important mark on one’s physio-psychological makeup. (shrink)

L'originalité de la philosophie de Platon et de Plotin est de situer l'origine de toutes choses dans un principe supérieur au monde physique et matériel. Cette décision philosophique, qui ne va pas de soi, visant à placer la cause de toutes choses dans un principe transcendant et immatériel, est concomitante d'un autre choix philosophique consistant à "séparer" la cause de son effet, le haut du bas, l'intelligible du sensible, l'invisible du visible, l'incorporel du corporel. De telles "séparations" poseront à Platon (...) et à Plotin le problème de l'unité du monde et des "relations" que ces deux niveaux différents peuvent ou doivent malgré tout entretenir afin d'éviter toute forme de dérive dualiste et de vision pessimiste du monde. Cet ouvrage propose d'affronter cette question épineuse et d'apprécier la pertinence de la solution qu'y apportent Platon et Plotin, en développant chacun une "philosophie de la relation" tout à fait originale et stimulante.

Dans Des hégémonies brisées, Reiner Schürmann pose que tout principe hégémonique est travaillé du dedans par une puissance anarchique qui brise sa normativité. Il en va ainsi du Premier Principe, l’Un, dans les Ennéades de Plotin. À partir d’une étude de la spécificité de la production de la matière par l’âme et de la notion d’audace [tólma], notre article soutient que le lieu de l’anarchie se trouve non pas dans l’Un, mais dans les âmes, c’est-à-dire à un niveau encore dépendant (...) de la principialité du principe. Explorant la notion paradoxale de « principe d’anarchie » telle qu’élaborée par Schürmann, l’objectif de l’article est de questionner la possibilité d’une normativité anarchique s’exerçant sans principialité hégémonique.

Although Plotinus’ two treatises on beauty could be taken to reflect an evolution in his thought, a careful examination shows that he consistently argues for a conception of beauty as the illuminated unity in multiplicity of the Intellect.

Le système métaphysique du platonicien chrétien Marsile Ficin se caractérise par une ample utilisation des analogies et, plus particulièrement, de l’analogie de la lumière. Compte tenu de l’énorme éventail de ces applications, le présent article se concentre sur une question spécifique, à savoir celle de la relation entre lumière et ombre en relation avec sa notion de matière, et sur un texte spécifique : le Commentaire sur les «Ennéades» de Plotin, que Ficin a publié vers la fin de sa carrière. (...) L’article se divise en trois sections : 1) Enquête sur une gamme d’applications de l’analogie de la lumière chez Ficin ; 2) Résumé de l’interprétation de Ficin concernant la doctrine de la matière (supérieure et inférieure) de Plotin, en particulier dans Ennéades I. 8, II. 4, et III. 6 ; 3) Discussion de la manière dont Ficin applique l’analogie de la lumière et de l’ombre à la doctrine de la matière. Un thème important de l’article est la presénce d’une tension structurelle entre les notions de matière en tant que continuum et en tant que «barrière», indiquée par l’analogie de l’ombre. Ce thème est exploité par Ficin en vue de renforcer la doctrine (dérivée de certains passages de Plotin) selon laquelle Dieu exerce la causalité sans aucune médiation entre lui et ses effets.

In this paper, I explore the centrality of διάνοια in Plotinus’ philosophy. Plotinus says that the real “we” is found to be the subject of διάνοια and “upwards.” This fundamental definition elicits several pressing questions. First, how is the subject of discursive reasoning related to the subject of appetitive and affective states? Second, how does the subject of discursive reasoning come to recognize its ultimate destiny as an undescended and disembodied intellect? Finally, why should we think that, as Plotinus says, (...) there is “no falsity” in discursive thinking? The answers to these questions begins with Plotinus’ reflections on Plato’s Divided Line and the sharp distinction between διάνοια and δόξα. I argue that διάνοια is the embodied expression of disembodied νοῦς. It is the focus of our ambiguous and conflicted personal identity. (shrink)

In this paper, I examine what is for Plato and all those who follow in his footsteps the ne plus ultra of cognition, namely, intuition (nous or noēsis). This is the paradigm of cognition, meaning that all forms of human (and even animal) cognition are inferior manifestations of this. Intuition is mental seeing, analogous to physical seeing. Among embodied souls, it is seeing a unity of some sort manifested in some diversity or plurality. Thus, someone who sees that the Morning (...) Star is the Evening Star, or that S at t1 is identical with S at t2, or that f = ma, etc., sees the unity ‘behind’ the diversity. The disembodied intellect that is the Demiurge (or, for Aristotle, the Unmoved Mover) sees paradigmatically the diversity of all intelligible being as a unity. Because mental seeing or intuition is paradigmatic for all cognition, cognition is essentially a unificatory process. Plato's method of collection and division displays both this process and its reverse. In the light of this core doctrine, I examine some of the insights that Platonists, especially Plotinus and Proclus, arrived at regarding a host of issues, including the nature of the first principle of all and the nature of normativity.

Plotinus stands at a crossroads in ancient philosophy, between the more than 600 years of philosophy that came before him and the new Platonic tradition. He was the first and perhaps the greatest systematizer of Plato's thought, and all later students of Plato in the following centuries approached Plato through him. This Companion from a new generation of ancient philosophy scholars reflects the current state of research on Plotinus, with chapters on topics including mathematics, fate and determinism, happiness, the theory (...) of forms, categories of reality, matter and evil, and Plotinus' legacy. The volume offers an accessible overview of the thought of one of the pivotal figures in the history of philosophy, and reveals his importance as a thinker whose impact goes far beyond his importance as an interpreter of Plato.
