The first book-length philosophical study on the Presocratic influences in Plotinus’ Enneads.

There are only two places in which Plato explicitly offers a critique of the sort of theory of forms presented in the Phaedo and Republic: at the beginning of the Parmenides and in the argument against the Friends of the Forms in the Sophist. An accurate account of the argument against the Friends, therefore, is crucial to a proper understanding of Plato’s metaphysics. How the argument against the Friends ought to be construed and what it aims to accomplish, however, are (...) matters of considerable controversy. My aim in this article is twofold. First, I show that the two readings of the argument against the Friends that dominate the contemporary literature – the “Cambridge Change” reading and the “Becoming-is-Being” reading – lack sufficient textual support. Second, I offer an alternative reading of the argument against the Friends that better explains both the text of 248a4–249d5 and the role the argument plays within the Stranger’s wider project of demonstrating that non-being is. My thesis is that the Stranger’s argument against the Friends seeks to demonstrate that the forms must be both at rest and moved, where “moved” has the sense of “affected.” To participate in a form is to be affected by that form. I argue that since, according to the Stranger, every form participates in some other forms, every form is “moved” in the sense that it is affected by the forms in which it participates. Likewise, I argue that every form is at rest in the sense that its unique nature remains unaffected by the other forms in which it participates. (shrink)

Parmenides believed that he had found the most reliable way of theorizing about ultimate reality. While natural philosophers conceptualized phenomenal differences to explain cosmic change, Parmenides used the least meaningful but most versatile verb in Ancient Greek to engage in a purely intellectual exploration of reality – one that transcended synchronous and asynchronous differences. In this article I explain how the verb εἰμί was useful to Parmenides in his attempt to overcome natural philosophy. First, I argue that the Eleatic philosopher (...) regarded νοεῖν and εἶναι as equivalent because εἰμί-clauses enabled him to express arguably any conceivable content without providing significant additional meaning. I then show that Parmenides’ concept of being implies the present tense and the imperfective aspect but is grounded in the lexical content of the verb εἰμί, which entails no inherent temporal limits. This explains why ἔστι, ἐόν, and εἶναι could be used to indicate unbounded actuality, regardless of whether these forms represented lexical predicates or auxiliaries for predication. Finally, I maintain that the suitability of εἰμί for talking about all kinds of things without introducing temporal limits allowed Parmenides to avoid what he saw as two mistakes made by natural philosophers: identifying ultimate reality with something that cannot cover the full extent of thought and confusing actuality with present occurrence.

What all contemporary so-called aristotelian realists have in common has been identified by David Armstrong as the principle of instantiation. This principle has been put forward in different versions, but all of them have the following simple consequence in common: uninstantiated universals do not exist. Such entities are for the lotus-eating Platonist to countenance, but not for any sort of moderate realist. I shall argue that this principle, in any guise, is not the best way to differentiate aristotelianism from Platonism. (...) In its place, I shall suggest that the best way to differentiate the two versions of realism from each other is by means of a far more powerful idea: naturalism. And the surprising conclusion given this means of differentiation will be that contrary to the usual proclamations, Platonism will be the more naturalistic theory, whereas aristotelianism will come to be seen for what it really is, namely, non-naturalistic.

The paper demonstrates that Parmenides’ monism is a logical consequence of his criteria for philosophy, in conjunction with the logical operators he uses, and their holistic connection. Parmenides, I argue, is the first philosopher to set out explicit criteria for philosophy, establishing as criterion not only consistency, but also what I call rational admissibility, the requirement when giving an account of something that the account be based on rational analysis and can withstand rational scrutiny. I give a detailed account of (...) the logical operators Parmenides uses in his argument and of the way in which his notion of being is tailored to fit both them and his criteria for philoso-phy.

At a crucial juncture in Plato’s Sophist, when the interlocutors have reached their deepest confusion about being and not-being, the Eleatic Visitor proclaims that there is yet hope. Insofar as they clarify one, he maintains, they will equally clarify the other. But what justifies the Visitor’s seemingly oracular prediction? A new interpretation explains how the Visitor’s hope is in fact warranted by the peculiar aporia they find themselves in. The passage describes a broader pattern of ‘exploring both sides’ that lends (...) insight into Plato’s aporetic method. (shrink)

This study considers Newton's views on space and time with respect to some important ontologies of substance in his period. Specifically, it deals in a philosophico-historical manner with his conception of substance, attribute, existence, to actuality and necessity. I show how Newton links these “features” of things to his conception of God's existence with respect of infinite space and time. Moreover, I argue that his ontology of space and time cannot be understood without fully appreciating how it relates to the (...) nature of Divine existence. In order to establish this, the ontology embodied in Newton's theory of predication is analysed, and shown to be different from the presuppositions of the ontological argument. From the historical point of view Gassendi's influence is stressed, via the mediation of Walter Charleton. Furthermore, Newton's thought on these matters is contrasted with Descartes's and Spinoza's. In point of fact, in his earliest notebook Newton recorded observations on Descartes's version of the ontological argument. Soon, however, he was to oppose the Cartesian conception of the actuality of Divine existence by means of arguments similar to those of Gassendi. Lastly, I suggest that the nature and extent of Henry More's influence on Newton's conception of how God relates to absolute space and time bears further examination. (shrink)

Does Parmenides really use the non-existence argument to deny the past?

In this paper I argue that the classic concept of eternity, as it is presented in Boethius, Anselm and Aquinas, must be understood to involve not only the claim that all temporal things are epistemically present to God, but also the claim that all temporal things areexistentially present to God insofar as they coexist timelessly in the eternal present. I further argue that the concept of eternity requires a tenseless view of time. If this is correct then the existence of (...) an eternal God logically depends on the truth of the tenseless account of time. I conclude by suggesting that the Christian theologian ought to reject a tenseless ontology. (shrink)

It is widely held that in Plato's Sophist, Forms rest or change or both. The received opinion is, however, false—or so I will argue. There is no direct support for it in the text and several passages tell against it. I will further argue that, contrary to the view of some scholars, Plato did not in this dialogue advocate a kind of change recognizable as 'Cambridge change', as applicable to his Forms. The reason that Forms neither change nor rest is (...) that they are purely intelligible entities, not susceptible to changing or being at rest. Since Plato continues in the Sophist to treat Forms as causes, it follows that Forms are changeless causes. I ask what conception of cause might allow for this view, and reject the suggestion that Plato was some kind of proto-dispositionalist about causation. Instead I suggest that he understood causation to incorporate a notion of structuring, such that Forms can be seen to structure their participants and so cause them to possess the attributes they possess.

Contrairement à la majorité des interprètes du Timée de Platon, nous ne croyons pas que la figure du démiurge représente réellement une cause productrice. Ce type de causalité, explicitement attribué au νοῦς dans le Phédon, ne peut, selon nous, être associé qu’à l’activité de l’âme du monde et des dieux de la tradition. Le démiurge joue un autre rôle. Représentant le meilleur des êtres intelligibles éternels (37a), un dieu éternel (34a), le démiurge ne peut, à ce titre, être un principe (...) de mouvement, puisque l’intelligible, selon Platon, n’exerce qu’une causalité paradigmatique. La figure du démiurge est, en fait, la représentation mythique de la causalité paradigmatique. Le démiurge représente, plus précisément, à titre de « fabricant » de l’espèce des dieux, la forme intelligible du dieu. Certaines caractéristiques du démiurge (sa corporéité, ses pensées et son activité productrice) sont indissociables de l’analogie employée pour représenter la dépendance des dieux à l’égard des formes intelligibles : le travail artisanal. Le démiurge, en tant que cause productrice, n’a pas de valeur ontologique réelle. Néanmoins, ce qu’il représente, la forme intelligible du dieu, constitue, selon Platon, la cause qui fonde l’immortalité de l’univers et des dieux de la tradition, une cause qui permet ainsi au νοῦς de ces divinités d’exercer leur causalité productrice.

A discussion of the arguments against the existence of time based upon its tripartition into past, present, and future found in SE M 10.197-202. It uncovers Sextus' major premises and assumptions for these arguments and, in particular, criticises his argument that the past and future do not exist because the former is no longer and the latter is not yet. It also places these arguments within the larger structure of Sextus' arguments on time in SE M 10 and considers these (...) arguments as an example of his general strategy for producing ataraxia by assembling opposing sets of argument on a given question.

This essay offers a reading of a difficult passage in the first book of Lucretius' "De Rerum Natura" in which the poet first explains the Epicurean account of time and then responds to a worry about the status of the past (1.459-82). It identifies two possible readings of the passage, one of which is compatible with the claim that the Epicureans were presentists about the past. Other evidence, particularly from Cicero "De Fato", suggests that the Epicureans maintained that all true (...) assertions must have a contemporaneous truth-maker and that no contingent future-tensed assertions are true. It appears, however, that they did not assert a symmetrical view of past-tensed assertions. There is no compelling reason, therefore, to think that the Epicureans were presentists about the past.

This paper is devoted to the Parmenides’ methodological preamble, in which Parmenides teaches how one is to lead a dialectical inquiry. The method presented there recalls the goddess’s advice, as presented by the historical Parmenides in his Poem, to think “the way of being and the way of non-being.” In Plato’s Parmenides, these two ways are seen as manners of examining a hypothesis. I explain that the method is exhaustive insofar as it requires repeatedly asking what the consequences are if (...) a thing does exist, or does not. Lastly, I suggest that the method should be distinguished from other dialectical practices found in Plato’s work. (shrink)

In contemporary metaphysics, the Eleatic Principle (EP) is a causal criterion for reality. Articulating the EP with precision is notoriously difficult. The criterion purportedly originates in Plato’s Sophist, when the Eleatic Visitor articulates the EP at 247d-e in the famous Battle of the Gods and the Giants. There, the Visitor proposes modifying the ontologies of both the Giants (who are materialists) and the Gods (who are friends of the many forms), using a version of the EP according to which only (...) items which have the capacity to affect or to be affected are real. Recently, it has been argued that while there are some genetic connections between the EP and the views of some of the historical Eleatics (Parmenides and Zeno), the views of Melissus are generally incompatible with the EP. This raises the following question: What, exactly, is Eleatic about the Eleatic Principle? In this paper, I look to the dialectical context in which the Visitor’s appeal to the EP appears, and I propose that there are at once three relevant senses of affecting and being affected in the text: (1) tangible contact (as in the interactions between the bodies of the materialists), (2) Cambridge change (as in the form's being affected by a soul via the act of coming to know), and (3) the notion of a cause that does not itself change (as in a form’s affecting another form, a soul, or any sensible item). I argue that these have clear parallels to the metaphysics of all three main Eleatic philosophers, and that the views of Parmenides, Zeno, and Melissus are therefore compatible with the EP. This has interesting consequences for narratives about the reception of the Eleatics in Plato, the inclusion of an Eleatic Visitor as an interlocutor in the Sophist, and for the metaphysics of subsequent schools (such as the Stoics) who are widely thought to have been influenced by the EP.

This catalogue is divided into two parts. Part 1 presents basic bibliographical information on books and journal issues that consist exclusively or in large part in papers devoted to the Presocratics and the Sophists. Part 2 lists the papers on Presocratic and Sophistic topics found in the volumes, providing name of author, title, and page numbers, and in the case of reprinted papers, the year of original publication. In some cases Part 2 lists the complete contents of volumes, not only (...) the Presocratic and Sophistic-related papers. Annual updates are submitted as additional files below. (shrink)

This page is dedicated to an analysis of the first section of Parmenides' Poem, the Way of Truth, with a selection of critical judgments by the most important commentators and critics. In the Annotated Bibliography I list the main critical editions (from the first printed edition of 1573 to present days) and the translations in English, French, German, Italian and Spanish, with a selection of studies on Parmenides; in future, a section will be dedicated to an examination of some critical (...) variants of the Greek text, with particular attention to corrections to the Diels-Kranz (abbreviated DK) edition of the Fragmente der Vorsokratiker. The fragments of Parmenides' Poem are cited according to Diels-Kranz numbering system as adopted in the 6th edition, Berlin 1952; the Poem is divided into three parts: the Proem fr. I, 1-32; the Way of Truth (Alethéia) from fr. II to VIII, 49, and the Way of Mortal Opinion (Doxa) fr. VIII, 50 to XIX, 3. (shrink)

The Arabic version of the Enneads is the earliest datable text in which appears the term "anniyya", that features in Avicenna’s metaphysics and lies in the background of the Latin definition of the Causa prima as esse tantum, typical of the Liber de Causis. This paper examines some examples of the use of "to be" in the Arabic translation of the Enneads. It also discusses the description of the First Cause as ‘pure Being’ or ‘first Being’ in the Arabic Plotinus, (...) and compares it with the Divine Names of the pseudo-Dionysius. icona . (shrink)
