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.

This volume dispels the idea that Platonism was an otherworldly enterprise which neglected the study of the natural world. Leading scholars examine how the Platonists of late antiquity sought to understand and explain natural phenomena: their essays offer a new understanding of the metaphysics of Platonism, and its place in the history of science.

Plato presents a hierarchy of five cities, each representing a structural arrangement of the soul. The timocratic soul, characterized by its governance by spirit and its consequent desire for esteem and aversion to shame, is ranked as the second-best kind of soul, though this should strike us as surprising since the timocratic figure would seem to be duplicitous, intellectually passive, and at the mercy of the fortuitous opinions of others. This timocrat's position thus raises problems concerning the intrinsic value of (...) the spirited part of the soul, problems that are best solved by comparing the auxiliary to the timocrat, both of whom represent different forms of second-best morality. A lengthy discussion of the early education's effect on the spirited part shows how the auxiliary represents the best kind of moral agent that the second-best nature (silver-souled individuals) can develop into. This is because the early education ensures that the auxiliary and the philosopher share the same basic structure of soul, with reason being in control of each, though the auxiliary's natural deficiencies create some limitations in terms of his or her moral self-sufficiency. The timocrat by contrast represents the second-best kind of moral agent that the best nature (gold-souled individuals) can develop into. The timocrat is morally inferior to the auxiliary and seems to embody Homeric shame-culture. Plato is critical of this approach to morality, but the timocrat justifiably occupies the second position in the hierarchy on account of his or her concern for the opinions of others.

Porphyry's account of the nature of seeds can shed light on some less appreciated details of Neoplatonic psychology, in particular on the interaction between individual souls. The process of producing the seed and the conception of the seed offer a physical instantiation of procession and reversion, activities that are central to Neoplatonic metaphysics. In an act analogous to procession, the seed is produced by the father's nature, and as such it is ontologically inferior to the father's nature. Thus, the seed (...) does not strictly speaking contain a full-fledged vegetative soul. Rather, it acquires its vegetative soul only while it is being actualized by an actual vegetative soul. This actualization takes place primarily at conception, where the seed as it were reverts back and becomes obedient to the mother's nature, but continues through the period of gestation. In this way, Porphyry can account both for maternal resemblance and for ideoplasty. He uses the Stoic language of complete blending to describe the mother's relation to the seed and embryo, and this reveals that he thinks of individuals as having their own unique individual natures (as opposed to sharing in a single universal nature). In the course of developing this theory, Porphyry makes significant revisions to his philosophical predecessors' views in both embryology and botany. He revises Aristotle's verdict on the relative importance of the female in generation as well as Theophrastus' explanation of the biological mechanics of grafting. Although Plotinus nowhere addresses embryology in the same detail as Porphyry does, we can conclude from his remarks on seeds and plants that his own views were similar to those of his student.

In Ennead II.1 (40) Plotinus is primarily concerned to argue for the everlastingness of the universe, the heavens, and the heavenly bodies as individual substances. Here he must grapple both with the philosophical issue of personal identity through time and with the rich tradition of cosmology which pitted the Platonists against the Aristotelians and Stoics. What results is a historically informed cosmological sketch explaining the constitution of the heavens as well as sublunar and celestial motion.

Forms, Souls, and Embryos allows readers coming from different backgrounds to appreciate the depth and originality with which the Neoplatonists engaged with and responded to a number of philosophical questions central to human reproduction, including: What is the causal explanation of the embryo's formation? How and to what extent are Platonic Forms involved? In what sense is a fetus 'alive,' and when does it become a human being? Where does the embryo's soul come from, and how is it connected to (...) its body?

Teratogenesis poses a real problem for all those who wish to see the natural world as a success story, and this includes the Neoplatonists. On their view even ordinary biological reproduction is governed by principles ultimately derived from intelligible Forms. Thus, the generation of terata would seem to call into question the very efficacy of these intelligible principles in the sensible world, since these would seem to be cases in which matter has gotten the upper hand over the intelligible. Although (...) the corpus of surviving Neoplatonic works offers no systematic discussion of the problems surrounding teratology, it is possible to find a number of passages which deal with the explanation of terata. In this article these passages are collected and discussed. It is argued inter alia that, far from capitulating in the face of this putative evidence against the full efficacy of intelligible causes in the world, the Neoplatonists managed to use these phenomena to the advantage of their own views.

David Foster Wallace was genuinely troubled by what he perceived to be a serious incongruity in the mental lives of elite athletes. To perform with grace and beauty, elite athletes must be ‘geniuses,’ yet in conversation and prose these same athletes often exhibit such vapidity and banality that he was tempted to simply write them off as unintelligent or worse. In response to this puzzle, Wallace developed different philosophical conceptions of the elite athlete aimed at bridging the gap between genius (...) and dumb jock. For Wallace, this was an exercise designed to help him live a more compassionate life. (shrink)

At the start of his treatise On the Universe, Plotinus announces his interest in the everlastingness of the universe. Yet, Plotinus never questions that the universe is in fact everlasting. Rather, his examination is limited to the cause of this everlastingness.In my dissertation, I offer a slightly revised text as well as completely new translation of this examination. In addition, an introductory essay and a lengthy commentary serve both to illuminate Plotinus' thought and to set the discussion into the larger (...) contexts of Plotinus' philosophy, and more generally of Platonism and Aristotelianism. As can be expected of commentaries, a considerable amount of space is devoted to a whole host of details that are only tangentially related to the treatise's main subject matter. ;As Plotinus realizes, there is a giant problem confronting a Platonist who wants to say that any sensible thing is everlasting. After all, a fundamental tenet of Platonism is that the sensible region is synonymous with coming-to-be and perishing with the apparent result that nothing in it can be everlasting. Nevertheless, Plotinus was convinced that the universe is everlasting. ;In order to establish this, Plotinus argues that both the universe, which Plotinus, like Plato, takes to be a living thing composed of body and soul, and the heavens suffer no external flux. The reasoning behind this is Aristotelian at heart: Material flux signals a lack of harmony between the living thing's body and soul. The union is in some sense unnatural so that the soul has to force the body to stay together as best it can, and this tension between the body and soul eventually manifests itself in the perishing of the living thing. Thus, external flux signals a tension between body and soul that inevitably leads to the composite living thing's destruction. Establishing that the universe suffers no flux is easy: Plotinus need only appeal to the fact that the universe has no exterior. In order to demonstrate this for the heavens, Plotinus shows that there is no exchange of matter between the heavens and the sublunar region. (shrink)

Concerning embryos, Porphyry takes an original view on issues that had been left undecided by his teacher Plotinus and earlier by the doctor Galen. What role is played in the development of the embryo by the souls or the natures of the father, of the mother, of the embryo, or of the whole world? Porphyry's detailed answer, in contrast to Aristotle's, gives a big role to the soul and to the nature of the mother, without, however, abandoning Aristotle's view that (...) the mother supplies no seed. In the fragments of "On What is in Our Power", "Porphyry" discusses Plato's idea that we choose each of our incarnations, and so are responsible for what happens in our lives. (shrink)

The concept of the world soul is difficult to understand in large part because over the course of history it has been invoked to very different ends and within the frameworks of very different philosophical systems, with very different concepts of the world soul emerging as a result. This volume brings together eleven chapters by leading philosophers in their respective fields that collectively explore the various ways in which this concept has been understood and employed, covering the following philosophical areas: (...) Platonism, Stoicism, Medieval, Indian (Vedāntic), Kabbalah, Renaissance, Early Modern, German Romanticism, German Idealism, American Transcendentalism, and contemporary quantum mechanics and panpsychism theories. In addition, short reflections illuminate the impact the concept of the world soul has had on a small selection of areas outside of philosophy: harmony, biology (spontaneous generation), the music of Henry Purcell, psychoanalysis, and Gaia theories.

Review on James Wilberding, Plotinus’ Cosmology. A Study of Ennead II.1 . Text, Translation, and Commentary, Oxford University Press, Oxford, 2006.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The New Cambridge Companion to Plotinus ed. by Lloyd P. Gerson and James WilberdingBrandon ZimmermanGERSON, Lloyd P. and James Wilberding, editors. The New Cambridge Companion to Plotinus. Cambridge: Cambridge University Press, 2022. xxiv + 471 pp. Cloth, $105.00; paper, $34.99The original 1996 Cambridge Companion to Plotinus had the advantage of being one of the few systematic studies of Plotinus available and was able to recruit (...) some of the pioneers in the field to epitomize their research. In recent times, scholarship on Neoplatonism has exploded with new commentaries on and translations of Plotinus's works as well as significant studies of his Platonic predecessors and successors. Given the difficulty of following, let alone mastering, the burgeoning scholarship on late antique philosophy, The New Cambridge Companion to Plotinus is a sample of the work of current, generally younger, scholars in the field, rather than a comprehensive study of Plotinus's sources, thought, and influence.Because they address philosophical questions from a comprehensive metaphysical framework, Plotinus's treatises are difficult to group systematically. The same is true of the contributions of this volume, which elude the editors' attempts to classify them into sections. The first three essays are on historical topics. Eric Perl presents examples of how Plotinus creatively reworks material from Plato and Aristotle. Sebastian Gertz explores Plotinus's knowledge of Gnosticism, outlines his criticism of it in II.9, and speculates on whether certain criticisms were meant to apply to Christianity as well. Marije Martijn summarizes the critical reception and development of Plotinus's ideas in later pagan Neoplatonism. Little connection is made between Plotinus and the preceding Platonic and Pythagorean revivals, and nothing more is said about his reception.The order of the remaining essays is generally the inverse of Porphyry's arrangement of the Enneads, insofar as they move from the first principle downward to conclude with humanity's place in the whole. In her interpretation of Plotinus's first principle, Gwenaëlle Aubry presents the power of the One as an intermediary between it and its effects. Unlike Perl, who depicts the One as pure activity, and Gatti, who in the 1996 volume said the One is self-creative freedom, Aubry denies both freedom and activity to the One. Mauro Bonazzi and Christian Tornau both cover Plotinus's account of the divine intellect that is identical with the Forms as a response to the challenge of skepticism. Bonazzi begins with the Middle Platonic debate over Plato's first principles, while Tornau works upward from how our participation in Intellect enables us to judge the truth of sense perceptions. Svelta Slaveva-Griffin tries to show how Number is a metaphysical principle for Plotinus, suggesting that there is participated One posterior to the transcendent One. Michael Griffin rediscovers Plotinus's important place in the late antique development of Aristotle's logic. Griffin summarizes his criticisms of Aristotle's categories as being inconsistent with Aristotle's own logical principles, and then presents Plotinus's own categories (really more like transcendentals) of intelligible being and then of sensibles. Similarly, D. M. Hutchinsin's summary of Plotinus on the composition of sensible bodies highlights [End Page 349] Plotinus's valid probing of the relation between the predicables and the categories, even if Plotinus himself would reduce bodies to heaps or bundles of qualities. Damian Caluori insightfully reconstructs Plotinus's account of body–soul relations and operations as a synthesis of Aristotelian principles, Galen's anatomical discoveries, and his own understanding of the soul as an active intelligible reality. Plotinus is far more concerned about the distinct nature of bodily reality than he is often given credit for. Transcending the narrow historical focus of this volume, Pauliina Remes meditates upon and praises Plotinus's contributions to the philosophical problem of self-knowledge. Riccardo Chiaradonna ably summarizes III.7 "On Eternity and Time," but with no comments on the significance of Plotinus's teachings. James Wilberding questions whether Nature, which is the aspect of the World-Soul at work in giving the cosmos its life and form, should be considered its own level of reality (hypostasis). Jan Opsomer summarizes Plotinus's idiosyncratic teaching that matter, despite ultimately originating from... (shrink)

There is a well-known tension in Plotinus' thought regarding the location of the intelligible region. He appears to make three mutually incompatible claims about it: (1) it is everywhere; (2) it is nowhere; and (3) it borders on the heavens, where the third claim is associated with Plotinus' affection for cosmic religion. Traditionally, although scholars have found a reasonable way to make sense of the compatibility of the first two claims, they have sought to relieve the tension generated by (3) (...) by both downplaying the importance of cosmic religion to Plotinus and reinterpreting his spatial language metaphorically. In this paper I argue that both of these maneuvers are unsatisfactory. Rather, it is possible to reconcile Plotinus' metaphysics with the world-view of cosmic religion (CR world-view), i.e., to retain the spatial sense of Plotinus' language without making his metaphysics incoherent. In the first part of this paper, I show that cosmic religion is not just an awkward appendage to Plotinus' metaphysics. After explaining what cosmic religion involves, I argue that the CR world-view is in fact central to his natural philosophy. Then, I turn to the problem of the compatibility between cosmic religion and Plotinus' thought. By carefully considering how Aristotle's Prime Mover is present to his universe, I show how we can make claims (2) and (3) compatible for Plotinus. Then, I argue that Plotinus' own account of the omnipresence of soul and its powers' actualizations in particular locations provides a parallel to the problem of the compatibility between (1) and (3), and further that these two accounts can be combined to resolve completely the tension between the CR world-view and Plotinus' metaphysics. In the final section, I discuss the implications this has for our understanding of the soul's ascent and descent. (shrink)

Structural realism is considered by many realists and antirealists alike as the most defensible form of scientific realism. There are now many forms of structural realism and an extensive literature about them. There are interesting connections with debates in metaphysics, philosophy of physics and philosophy of mathematics. This entry is intended to be a comprehensive survey of the field.

Moral philosophy is the study of what morality is and what it requires of us. As Socrates said, it's about "how we ought to live"-and why. It would be helpful if we could begin with a simple, uncontroversial definition of what morality is. Unfortunately, we cannot. There are many rival theories, each expounding a different conception of what it means to live morally, and any definition that goes beyond Socrates's simple formula-tion is bound to offend at least one of them. (...) This should make us cautious, but it need not paralyze us. In this chapter, I will describe the "minimum conception" of morality. (shrink)

For this 1897 publication, the American philosopher William James brought together ten essays, some of which were originally talks given to Ivy League societies. Accessible to a broader audience, these non-technical essays illustrate the author's pragmatic approach to belief and morality, arguing for faith and action in spite of uncertainty. James thought his audiences suffered 'paralysis of their native capacity for faith' while awaiting scientific grounds for belief. His response consisted in an attitude of 'radical empiricism', which deals (...) practically rather than ideologically with real-world phenomena. When facing a 'momentous' decision about belief, he says, we both can and must choose the best hypothesis. The first four essays apply this principle to religious faith, and the rest explore the pragmatic approach to such topics as determinism, ethics and individual achievement. James developed his ideas further in The Varieties of Religious Experience and Pragmatism, both of which are reissued in this series. (shrink)
