The present PhD dissertation aims to examine the relation between modality and change in Aristotle’s metaphysics. -/- On the one hand, Aristotle supports his modal realism (i.e., worldly objects have modal properties - potentialities and essences - that ground the ascriptions of possibility and necessity) by arguing that the rejection of modal realism makes change inexplicable, or, worse, banishes it from the realm of reality. On the other hand, the Stagirite analyses processes by means of modal notions (‘change is the (...) actuality of what is virtual insofar as it is virtual’). In other words: to grasp what change is, one has to resort to the modal idiom of potentialities, while the fact that there is change is indicative of the fact that nature is full of modal properties. -/- Aristotle’s modal and kinetic realism finds a negative in the figure of the Megaric Diodorus Kronus. The polemical situation of Greek philosophy has indeed the dialectical advantage of not opposing the Aristotelian position to a sui generis straw man. Both in its reduction of modal judgements to temporal quantifications and in its dissolution of the reality of the state-of-being-in-motion in favour of a cinematographic view of processes, the philosophical figure of reductionist antirealism embodied by Diodorus constitutes an alternative that takes the opposite view of Aristotle’s realism. -/- The present study is structured as a discussion between these two positions. In the face of Diodorus’ antirealist challenges, Aristotle articulates modal and kinetic considerations: the answers he gives to Diodorus’ puzzles thus provide valuable insight into his metaphysics. Moreover, the examination of Aristotle’s and Diodorus’ metaphysics, because of their insight and originality, will not fail to interest the philosopher concerned with the metaphysical foundations of modern physics, insofar as the entanglement between modalities and processes is nowadays at the core of mechanics (phase spaces, path integrals, etc.).

An aporia posed by Theophrastus prompts Priscian to describe the process by which perception formally assimilates to its object as a progressive perfection. I present an interpretation of Priscian’s account of perception’s progressive perfection. And I consider a dilemma for the general class of accounts to which Priscian’s belongs based on related problems raised by Plotinus and Aquinas.

Drawing on recent scholarship and delving systematically into Iamblichean texts, these ten papers establish Iamblichus as the great innovator of Neoplatonic philosophy who broadened its appeal for future generations of philosophers.

Simplicius’ project of harmonizing previous philosophers deserves to be taken seriously as both a philosophical and an interpretive project. Simplicius follows Aristotle himself in developing charitable interpretations of his predecessors: his distinctive project, in the Neoplatonic context, is the rehabilitation of the Presocratics (especially Parmenides, Anaxagoras and Empedocles) from a Platonic-Aristotelian perspective. Simplicius’ harmonizations involve hermeneutic techniques which are recognisably those of the serious historian of philosophy; and harmonization itself has a distinguished history as a constructive philosophical method.

In De Trinitate 10, Augustine offers an argument that seemingly proceeds from certain premises about self-knowledge to the conclusion that the mind is incorporeal. Although the argument has sometimes been compared to later Cartesian arguments, it has received relatively little philosophical attention. In this paper, I offer a detailed analysis and original interpretation of Augustine's argument and argue that it is not vulnerable to some of the main objections which have been raised against it. I go on to argue that (...) while an important part of Augustine's argument does face several hitherto neglected objections, Augustine's ultimate case for the incorporeality of the mind is somewhat different and more successful than one might initially think.

This paper studies moral education in Proclus and Iamblichus. The first section analyses Proclus’ theory of moral education and its psychological underpinnings. Especially important in this context is the identification of the faculty of choice with the passive or teachable intellect. The second section investigates the implementation of this theory into practice with the help of Iamblichus’ Letter to Sopater: On Bringing up Children. The final section demonstrates how Proclus’ famous tripartite division of poetry should be understood in the context (...) of his program of moral education. (shrink)

Contemporary scholarship accents incipient theurgical practice for Plotinus; this lends a certain urgency to the question of his acceptance of magic. While use of magic recorded in Porphyry's Vita Plotini has received considerable attention, far less has been done to analyze actual discussion in the Enneads. Examination of key passages brings to light the context for discussion of magic, particularly issues of sympathy, prayer, astrology and divination. Equally important is Plotinus' understanding of the cosmos and role of the heavenly bodies. (...) Plotinus' affirmation of the highest part of the soul as undescended, together with the claim that our soul has a common origin with the World Soul in Soul-Hypostasis, is significant for the relative unimportance he attributes to the role and effect of magic.

A debate between Proclus and Damascius over whether intellect ‘remembers’ the forms in contemplating them is explained by Professor Adamson as a disagreement over the nature of memory looking back to Plato and Aristotle. But I argue that it is rather symptomatic of a disagreement stretching back through Plotinus to Middle Platonism over the nature of the intellect. This gives the debate its urgency; and it coheres better with the fact that, Plato and Aristotle aside, there is vanishingly little evidence (...) in ancient philosophy for a thematized interest in memory.

In The First Principle, Jonathan Greig examines the philosophical theology of the two Neoplatonists, Proclus and Damascius (5th–6th centuries A.D.), on the One as the first cause. Both philosophers address a tension in the Neoplatonic tradition: namely that the One was seen as absolutely transcendent, yet it was also seen as intimately related to other things as the source of their unity and being. Proclus’ solution is to posit intermediate causes after the One, while Damascius posits a distinct principle, the (...) ‘Ineffable’, above the One. This book provides a new, thorough study of the theories of causation that lead each to their respective position and reveals crucial insights involved in a rigorous negative theology employed in metaphysics.

Damascio divide su Comentario al Fedón en tres partes. La última está dedicada al mito escatológico, el cual, a su vez, es dividido también en tres partes. Este descenso en el Hades se lee conjuntamente con otros dos mitos platónicos que versan sobre el destino del alma, el del Gorgias y el de República. En tal concepción triádica Damascio es deudor de Proclo, quien fue el primero en mostrar la imbricación entre estos tres diálogos. En consecuencia, este trabajo intentará mostrar (...) qué sentido conceden al mito los neoplatónicos y de qué manera se relaciona este con la vida del alma, ya que ambos pensadores sostienen que parte de dicha vida transcurre en la génesis, en la región de la desemejanza, en la cual se juega definitivamente su condición escatológica. Damascius divides into three parts his Commentary on Plato's Phaedo. The third one is dedicated to the eschatological myth, which is divided, in turn, into three parts. This descent into Hades can be read together with other two Platonic myths dealing with the fate of the soul, to know: Gorgias and The Republic. In this triadic conception, Damascius owes a debt to Proclus, who was the first to show a mutual overlapping between these three dialogues. Therefore, this paper will try to show the sense granted to the myth by the neo-platonic philosophers and how it is related to the life of soul, since both thinkers argue that a part of life occurs in the genesis, in the area of dissimilarity, where its eschatological condition takes place.

This article analyzes the concept of self-constitution in Damascius’ treatises De principiis and In Parmenidem. On the one hand, I try to see how self-constitution functions within the framework of reality. I identify the different levels of self-constituted reality, showing that each of these levels is also constituted by the absolute One, which is the cause of all things. Self-constitution is present throughout the process in which the One is slowly in labor towards plurality, starting from the highest level of (...) intelligible being down to the level of the particular soul. On the other hand, I also try to show how self-constitution appears at a discursive level. In this context I discuss its crucial role in Damascius’ interpretation of the second and third hypotheses in Plato’s dialogue Parmenides. (shrink)

Las Sentencias de Porfirio, que constituyen un compendio de las Enéadas de Plotino, incluyen una revisión del locus vexatus de platonismo del siglo III, que tiene su origen en la interpretación de un controvertido pasaje del Timeo, 39e. Revisaremos los antecedentes de Porfirio, bajo la influencia de Longino, y la polémica suscitada con Plotino y Amelio a su llegada a Roma. Su posterior "retractación" le lleva a aceptar que la Inteligencia se identifica con la multiplicidad de los inteligibles que intelige. (...) La Inteligencia es sujeto inteligente y, al mismo tiempo, objeto inteligido, es decir, ejerce sobre sí misma su propia actividad intelectual. Nuestro análisis tratará de poner en conexión textos de las Sentencias, particularmente provenientes de la 43, con pasajes extraídos de los tratados plotinianos. The Sentences of Porphyry, that are a compendium of the Plotinus Enneads, include a review of the locus vexatus of the third century Platonism, which has its origin in the interpretation of a controversial passage of Timaeus, 39e. We will review the historical causes of Porphyry, under Longinus influence, and the controversy with Amelius and Plotinus on his arrival in Rome. His subsequent "retraction" takes him to accept that Intellect is identified with the multiplicity of intellections that intelligizes. Intellect is an intelligent subject and, at the same time, an intelligized object, that is, itself exerts on its own intellectual activity. Our analysis will seek to bring together texts of the Sentences, particularly from the 43, with excerpts from Plotinus treaties. (shrink)
