One Stoic response to the skeptical indistinguishability argument is that it fails to account for expertise: the Stoics allow that while two similar objects create indistinguishable appearances in the amateur, this is not true of the expert, whose appearances succeed in discriminating the pair. This paper re-examines the motivations for this Stoic response, and argues that it reveals the Stoic claim that, in generating a kataleptic appearance, the perceiver’s mind is active, insofar as it applies concepts matching the perceptual stimulus. (...) I argue that this claim is reflected in the Stoic definition of the kataleptic appearance, and that it respects their more general account of mental representation. I further suggest that, in attributing some activity to the mind in creating each kataleptic appearance, and in claiming that the expert’s mind allows her to form more kataleptic appearances than the amateur, the Stoics draw inspiration from the wax tablet model in Plato’s Theaetetus (190e–196d), where Socrates distinguishes the wise from the ignorant on the basis of how well they match sensory input with its appropriate mental ‘seal’ (σφραγίς).

We tend to talk about (refer to, quantify over) parts in the same way in which we talk about whole objects. Yet a part is not something to be included in an inventory of the world over and above the whole to which it belongs, and a whole is not something to be included in the inventory over and above its constituent parts. This paper is an attempt to clarify a way of dealing with this tension which may be labeled (...) the Minimalist View: An element in the field of a part-whole relation is to be included in an inventory of the world if and only if it does not overlap any distinct element that is itself included in the inventory.

Mereological principles are often controversial; perhaps the most stark contrast is between those who claim that Weak Supplementation is analytic—constitutive of our notion of proper parthood—and those who argue that the principle is simply false, and subject to many counterexamples. The aim of this paper is to diagnose the source of this dispute. I’ll suggest that the dispute has arisen by participants failing to be sensitive to two different conceptions of proper parthood: the outstripping conception and the non-identity conception. I’ll (...) argue that the outstripping conception, can deliver the analyticity of Weak Supplementation on at least one sense of ‘analyticity’. I’ll also suggest that the non-identity conception cannot do so independently of considerations to do with mereological extensionality. (shrink)

According to the Stoics, ordinary unified bodies—animals, plants, and inanimate natural bodies—each have a single cause of unity and being: pneuma. Pneuma itself has no distinct cause of unity; on the contrary, it acts as a cause of unity and being for itself. In this paper, I show how pneuma is supposed to be able to unify itself and other bodies in virtue of its characteristic tensile motion (τονικὴ κίνησις). Thus, we will see how the Stoics could have hoped to (...) account for corporeal unity by positing another body (pneuma) apparently itself in need of unification. (shrink)

Standard lore has it that a proper name is a temporally rigid designator. It picks out the same entity at every time at which it picks out an entity at all. If the entity in question is an enduring continuant then we know what this means, though we are also stuck with a host of metaphysical puzzles concerning endurance itself. If the entity in question is a perdurant then the rigidity claim is trivial, though one is left wondering how it (...) is that different speakers ever manage to pick out one and the same entity when a host of suitable, overlapping candidates are available. But what if the entity in question is neither a continuant nor a perdurant? What if the things we talk about in ordinary language are time-bound entities that cannot truly be said to persist through time, or stage sequences whose unity resides exclusively in our minds--like the “waves” at the stadium or the characters of a cartoon? In such cases the rigidity claim can’t be right and a counterpart-theoretic semantics seems required. Is that bad? I say it isn’t. And it had better not be, if that turns out to be the best metaphysical option we have. (shrink)

The Stoics’ theory of kataleptic impressions looks different once we attend to their analysis of the Sorites paradox. In defending this view, I reject the long-standing assumption that the Stoics develop their theory by focusing on sensory impressions. The Stoic approach to vagueness shows, for example, that non-sensory impressions can be seemingly indistinguishable by belonging to a series. It also draws attention to an understudied dimension of Stoic theory: in aiming to assent only to kataleptic impressions, one aims to avoid (...) not only assent to false impressions but also assent to those that are neither true nor false.

This paper focuses on the narrative aspect of Seneca’s idea of self-transformation. It compares Seneca’s viewpoint with some modern notions of the narrative self to highlight some parallels and significant differences between the ancient and modern conceptions and it establishes the reading of some parts of De Brev. Vit. in the context of other passages as concerned with the narrative self. The paper argues, amongst other points, that in Ep. 83.1–3, Seneca extends the practice of meditatio (ethically directed self-examination) by (...) incorporating the construction of a narrative self into this process, in dual roles, as examiner and examined. It concludes that Seneca expected us to avail ourselves of a similar self-assessment based on a dialogue with philosophical texts. (shrink)

The Stoics are famously committed to the thesis that only bodies are, and for this reason they are rightly called “corporealists.” They are also famously compared to Plato’s earthborn Giants in the Sophist, and rightly so given their steadfast commitment to body as being. But the Stoics also notoriously turn the tables on Plato and coopt his “dunamis proposal” that being is whatever can act or be acted upon to underwrite their commitment to body rather than shrink from it as (...) the Giants do. The substance of Stoic corporealism, however, has not been fully appreciated. This paper argues that Stoic corporealism goes beyond the dunamis proposal, which is simply an ontological criterion for being, to the metaphysics of body. This involves, first, an account of body as metaphysically simple and hence fundamental; second, an account of body as malleable and continuous, hence fit for blending (krasis di’ holou) and composition. In addition, the metaphysics of body involves a distinction between this composition relation seen in the cosmology, and the constitution relation by which the four-fold schema called the Stoic Categories proceeds, e.g. the relation between a statue and its clay, or a fist and its underlying hand. It has not been appreciated that the cosmology and the Categories are distinct — and complementary — explanatory enterprises, the one accounting for generation and unity, the other taking those individuals once generated, and giving a mereological analysis of their identity and persistence conditions, kinds, and qualities. The result is an elegant division of Plato’s labor from the Battle of Gods and Giants. On the one hand, the Stoics rehabilitate the crude cosmology of the Presocratics to deliver generation and unity in completely corporeal terms, and that work is found in their Physics. On the other hand, they reform the Giants and “dare to corporealize,” delivering all manner of predication (from identity to the virtues), and that work is found in Stoic Logic. Recognizing the distinctness of these explanatory enterprises helps dissolve scholarly puzzles, and harmonizes the Stoics with themselves. (shrink)

This essay argues the Stoics are rightly regarded as pantheists. Their view differs from many forms of pantheism by accepting the notion of a personal god who exercises divine providence. Moreover, Stoic pantheism is utterly inimical to a deep ecology ethic. I argue that these features are nonetheless consistent with the claim that they are pantheists. The essay also considers the arguments offered by the Stoics. They thought that their pantheistic conclusion was an extension of the best science of their (...) day. Some of their most interesting arguments are thusa posteriori. (shrink)

In this paper, we present an extensional system of mereology suitable to account for the intuitive distinction between heaplike and non-heaplike entities. Since the need to capture this distinction has been a key motivation for non-extensional mereologies, we first assess the main non-extensional systems advanced in the last years and highlight some mereological and metaphysical difficulties they involve. We then advance a novel program, according to which the distinction between heaplike and non-heaplike entities can be accounted for by bringing together (...) the parthood relation characterized by classical extensional mereology and an Aristotelian extensional notion of potential parthood. Thus, while rejecting the thesis of mereological monism, our proposal is consistent with the thesis of mereological extensionalism. We show that within this framework it is possible to characterize the above-mentioned distinction, to define the relation of material constitution, and to capture three fundamental standpoints in metaphysics.

In an earlier paper in Theoria, I discussed an argument based on the idea of “soul-switching” that attempted to undermine the immaterialist account of human beings. The present paper deals with a parity argument against that argument in which the idea of “body-switching” plays a pivotal role. I call these two arguments, that have been reported by Razi (d. 1210), respectively “the soul-switching argument” and “the body-switching argument”. After some introductory remarks, section 2 of the paper describes the structure of (...) the latter argument. Section 3 considers some philosophical discussions in the ancient, modern, and contemporary eras in which the idea of body-switching (or some similar conception) plays a major role. In the following section 4, some criticisms of the argument are discussed and a general response that is meant to cover a broad range of objections is considered. This paper shows that the body-switching argument reported by Razi is a methodological antecedent of several contemporary arguments in defence of substance dualism. (shrink)

The Stoics have often been compared to the earthborn Giants in the Battle of Gods and Giants in Plato’s Sophist, but with diverging opinions about the lessons they drew in reaction to Plato. At issue are questions about what in the Sophist the Stoics were reacting to, how the Stoics are like and unlike the Giants, the status of being for the Stoics, and the extent to which they were Platonizing with their incorporeals. With these open questions in mind, I (...) reexamine the Sophist from the Stoic perspective, finding eight distinct challenges that are likely to have been salient to the Stoics, and offer a new account of the Stoics as responding to these challenges with an innovative ontology that prises apart something from being to make room for what is not, and a sophisticated one-world metaphysics that grounds everything there is in two fundamental bodies.

Simplicius’ Commentary on Aristotle’s Categories contains the most extended testimony about the Stoic conception of acting (ποιεῖν) and undergoing (πάσχειν). Simplicius ascribed to the Stoics the idea that acting and undergoing are to be reduced to the movement. To this opinion Simplicius opposed the Aristotelian view according to which acting and undergoing are two different categories. In this paper I intend to outline the original Stoic position comparing the reportage of Simplicius with other Stoic sources. Later, I will deal with (...) Boethus’ defense of the distinction between the categories of acting and undergoing. I will argue that Boethus directly reacted against the Stoic opinion reformulating it in Aristotelian language.

Considering topology as an extension of mereology, this paper analyses topological variants of mereological essentialism (the thesis that an object could not have different parts than the ones it has). In particular, we examine de dicto and de re versions of two theses: (i) that an object cannot change its external connections (e.g., adjacent objects cannot be separated), and (ii) that an object cannot change its topological genus (e.g., a doughnut cannot turn into a sphere). Stronger forms of structural essentialism, (...) such as morphological essentialism (an object cannot change shape) and locative essentialism (an object cannot change position) are also examined.

Mereotopology is today regarded as a major tool for ontological analysis, and for many good reasons. There are, however, a number of open questions that call for an answer. Some are philosophical, others have direct applicative import, but all are crucial for a proper assessment of the strengths and limits of mereotopology. This paper is an attempt to put sum order in this area.

The phasalist solution to the classic puzzle of the statue and the piece of clay only works for some coincidence puzzles and not others. To address this limitation of phasalism, I develop a novel approach to coincidence puzzles that permits different kinds of coincidence puzzles to be solved in different ways, provided that each solution satisfies certain constraints inspired by the phasalist solution to the statue puzzle. I apply my approach to four different kinds of coincidence puzzles, and I argue (...) that it is no less plausible than rival approaches in the literature. (shrink)

Cet article vise à comprendre la théorie stoïcienne de la deixis afin d’expliquer l’importance accordée par les stoïciens aux pronoms démonstratifs et aux énoncés qu’ils composent, c’est-à-dire les propositions dites définitives. Nous montrons que ces propositions sont privilégiées pour des raisons à la fois ontologiques et épistémologiques en raison des propriétés sémantiques de leur sujet. Elles sont privilégiées d’un point de vue ontologique parce que la deixis grâce à laquelle leur sujet fait référence au réel crée une relation privilégiée à (...) la matière, la catégorie ontologique stoïcienne fondamentale. De plus, ces sujets requièrent que leur référent existe et soit présent et saisissable. Ces énoncés sont d’autre part privilégiés d’un point de vue épistémologique parce qu’ils sont fondamentaux dans l’acquisition de la connaissance. Nous suggérons enfin que tous les énoncés apparemment définis ne le sont pas en effet, et considérons quand et sous quelles conditions une référence déictique est réussie. (shrink)

sProblems about the nature of integral parts and wholes were central to twelfth-century discussions of the individuation and persistence over time of both substances and artifacts. This paper examines in detail Abaelard’s contribution to these discussions arguing that Abaelard proposes a solution to these problems which preserves our common sense intuitions about identity over time. In Abaelard’s work we find an explicit solution to the problem of the identity over time of living things which appeals to the persistence of the (...) vegetative soul through the loss or addition of corporeal matter. In work from the school of the Montani we apparently also have an account of Abaelard’s solution to the problem of the identity over time of artifacts which distinguishes between the role of a part in an integral whole and the material which plays that role such that the role persists when the matter is replaced.

The theory according to which most ordinary objects are mere “entia successiva”—sequences of distinct mereological aggregates, whose unity resides exclusively in our minds—is a variant of the standard, three-dimensional conception of objects. For the aggregates are, at bottom, endurants, i.e., entities that persist through time by being fully present at any time at which they exist. In this paper I compare this theory with the so-called “stage view”, according to which ordinary objects—indeed, all objects—are sequences of momentary entities that cannot (...) truly be said to persist through time. Both theories face a number of intuitive difficulties but the stage view, I argue, has a lot more to offer in return. (shrink)

Chrysippe a élaboré une stratégie contre l’argument Dominateur de Diodore afin d’éviter le nécessitarisme impliqué par le rejet des possibilités contrefactuelles. Alexandre d’Aphrodise lui oppose sa doctrine du retour périodique (Sur les Premiers Analytiques d’Aristote 180, 28 – 181, 34). Son objection repose sur une conception numérique de l’identité des individus à travers les cycles. Chrysippe n’admettant que leur ressemblance sinon leur stricte identité qualitative, sa doctrine du retour autorise les possibilités contrefactuelles.

Apeiron Issue: Ahead of print. This paper is dedicated to exploring the alleged difference between Cleanthes’ and Chrysippus’ accounts of the post-mortal survival of the souls and the conceptions of personal identity that these accounts underpin. I argue that while Cleanthes conceptualised the personal identity as grounded in the rational soul, Chrysippus conceptualised it as an embodied rational soul. I also suggest that this difference between the two early Stoics might have been due to Chrysippus' metaphysical commitments arising from his (...) response to the Growing Argument put forth by the Academics rather than the critique of his teacher.

At Outlines of Pyrrhonism (PH) 2.227–8, Sextus Empiricus argues that certain entities which his adversaries hold to be one and the same for different individuals are in fact not. This he does by, among other things, considering the truth-value of sentences of which the subject is a common noun, thereby drawing an interesting connection between metaphysics and semantics. In this article, I provide a careful analysis of Sextus’ arguments at PH 2.227–8 and explore the origins and limits of such a (...) connection. In particular, I argue that Sextus’ argument at PH 2.227 probably reflects a Stoic argument against Aristotelian essences, thereby relying on specifically Stoic doctrines about universals and common nouns, whereas his next argument at PH 2.228 targets accidents. If this is true, it follows that the overall structure of PH 2.227–8 fits well with the typically Aristotelian distinction between essence and accident. (shrink)

This paper focuses on the materialistic account of the blending and the way it shapes an original organism model. I aim to shed light on the threads of connections we can gather between the Presocratic and the Stoic views on the physical krasis of the body. The Stoics share with Parmenides and Empedocles the idea of a single material cosmic continuum in which thought and perception depend on the various blendings of the physical constituents of the body. Both of these (...) naturalistic traditions are committed to the view that substance is continuous and undergoes constant and qualitative change. My point is to underline how this view of a sympathetic cosmos presupposes a model of the individuality that is radically open. Thus, by taking off the notion of the krasis, the Stoics take off a problem – namely, that of the organism – that is first fleshed out by the Presocratics – Parmenides and Empedocles in particular – philosophers. In this respect, the Stoic view of relational identity indebts to the Presocratic account, beyond and against the Aristotelian one. (shrink)

In this paper, I tackle the problem of diachronic identity. Far from providing a criterion for identity over time, the aim of this work is to understand if this issue pertains to ontology, conceived as that part of philosophy that tries to answer the question about what entities exist, or metaphysics, conceived as that part of philosophy that tries to explain, of those entities, what they are. On the face of it, only metaphysics has the task to solve this problem, (...) but I argue that this is false. Through the analysis of different theories concerning identity through time, I show how both ontology and metaphysics are concerned with the problem of diachronic identity, and how actually ontology turns out to be primary in solving the problem.

In 'Chrysippus' Puzzle about Identity', John Bowin (thereafter JB) cogently strengthens David Sedley's reading of the puzzle of Chrysippus as a reductio ad absurdum of the Growing Argument. For Sedley, Chrysippus reduces to absurdity the assumption that matter is the sole principle of identity by refuting its presupposition that the two protagonists of the puzzle, namely Theon and Dion, are related as part to the whole. According to Plutarch's Comm. not. 1083 a8-c1, however, the Growing Argument concludes by posing that (...) growth is actually 'generation' and 'destruction'. In order to avoid the contradiction, Theon should have perished rather than become a part of Dion. JB attempts to answer the questions of whether within the Growing Argument there are elements against Theon being a living part of Dion. He shows that in both Epicharmus' fragment 2 and Plutarch's Comm.not. 1083b 308 "there is nothing to block the inference from matter being the sole principle of identity to the possibility that Theon could be a part of Dion" (246). Again, in exploring whether the above contradiction can be solved, he convincingly argues against Epicharmus' and Plutarch's reading of growth as generation and destruction. In the last part of his article, JB stresses that the reductio ad absurdum of the Growing Argument can be tackled without introducing the concept of 'peculiarly qualified individuals'.

This is a position article summarizing our approach to the philosophy of space and spatial representation. Our concern is mostly methodological: above all, we argue that a number of philosophical puzzles that arise in this field—puzzles concerning the nature of spatial entities, their material and mereological constitution, their relationship with the space that they occupy—stem from a confusion between semantic issues and true metaphysical concerns.

In this paper I focus on the relationships between language, definition and being in Antisthenes. I start from Plato’s Sophist 251b–c, in which the reference to the ὀψιμαθεῖς stands out, and I conclude that it is not possible to identify these characters with Antisthenes. The conception of ὀψιμαθεῖς provides for the exclusive legitimacy of identical judgments, exploiting in an eristic sense an evident Eleatic legacy. But this position, rather than concordances, reveals serious opposition to what is surely known to us (...) of the logical and linguistic doctrines of Antisthenes. The most explicit testimony about the relationship between language and being in Antisthenes is handed down by Porphyry, who attributes to Antisthenes the equation λέγειν = λέγειν τι = λέγειν τὸ ὄν. My analysis intends to show that this equation is assumed by Antisthenes through a Socratic mediation and has a double objective: to ensure an objective reference of language, as opposed to Gorgias’ self-referential conception of language, and to nullify the antilogy, which is typical of sophistic argumentation. To it Antisthenes contrasts the ἐπίσκεψις τῶν ὀνομάτων, which is a development of Socratic ἐξετάζειν, and whose aim is to reach, at the end of the examination, no longer just a ὁμολογία, but a definition valid once and for all. Antisthenes is aware that there is a distinction between essence and quality, and with this, he moves a first important step beyond the univocal conception of being proper to Parmenides. The doxography will sum up Antisthenes’ position by describing him as the first philosopher to advance a definition of logos, i. e., definition. He bases his theory of definition on the identification of that attribute which is ἴδιον καὶ οἰκεῖον of the proposed object. Antisthenes coined the phrase τὸ τί ἦν to designate what the predicate is meant to say in a definition, i. e., the proper quality. This expression does not seem to identify the general notion of a predicate as such, but rather to indicate the determination or qualification necessary to actually define the object in question. In the final part of my article, I examine some testimonies that show how, with his theory of definition, Antisthenes is, and was considered already in antiquity, the precursor of the Stoic theory of definition, whose objective is, according to Chrysippus’ formula, to provide the explanation of what is proper (ἰδίου ἀπόδοσις).

The Doctrine of Potential Parts says that proper undetached parts are merely potential entities, entities that do not exist but would exist if they were detached from the rest. They are just aspects of the whole to which they belong, ways in which the whole could be broken down, and talk of such parts is really just talk about the modal properties of the whole. Here I offer a reconstruction of this doctrine and present an argument to illustrate its hidden (...) kinship with another, parallel but independent doctrine Doctrine of Potential Wholes. According to this second doctrine, disconnected wholes (i.e., wholes that are not in one piece) are in turn potential entities, entities that do not exist but would exist if their parts were suitably conjoined.

In Epicurean cosmology, material reconstitution, or palingenesis (παλιγγενεσία) is the necessary consequence of the infinity of time and the eternity of atoms. I examine Lucretius’ treatment of this phenomenon (DRN 3.843–864) and consider the extent to which his view enables us to develop an Epicurean response to the question: what makes a person at two different times one and the same person? I offer a reading of this passage in the light of modern accounts of persistence and identity, and what (...) Lucretius states in Books 3 and 4 about memory and the soul’s motions. Guided by the metaphysical implications of this analysis, I determine the type of relation which, according to Lucretius, holds between the mental and the physical. (shrink)

This paper attempts to trace part of the history of medical and philosophical exchanges within the materialist tradition. I focus on this decisive role that they play on the emergence of organismic conception of the body. From its very beginnings, medical thought as the thought of mixture and as psychophysiology has been in close connection with the pre-Socratic tradition, and with Empedocles in particular. Both of them propose accounts of the blending as protoconceptions of an organic model of the body. (...) In the regard, the Stoic conception of krasis and the new model of the organismic individuality that it defines indebt to this medical and philosophical account. In this regard, the Galenic thought of mixture as an immanent and dynamic unity is also part of this materialistic and corporeist tradition. Within it, individual identity is conceived as fundamentally relational. It benefits from an undeniable Stoic account, while giving it an unprecedented medical extension. (shrink)

With the use of a particular metaphor, which appears at the end of the Cratylus and is taken up with perfect symmetry at the beginning of the Theaetetus, Plato certainly wanted to indicate the succession of Cratylus–Theaetetus as an order for reading the two dialogues, which Trasillus faithfully reproduced in structuring the second tetralogy of Platonic dialogues. The claim of the theory of ideas, with which the Cratylus ends, must therefore be considered the background in which to place not only (...) the analysis of the name carried out in the Cratylus, but also the discussion and criticism of the epistemological theories examined and refuted in the Theaetetus. The transition from the discussion of the name to that of the logos is another important theoretical element that connects the two dialogues. Another one is the theory of knowledge, already precisely elaborated in the Cratylus, and taken up and deepened in the Theaetetus. Finally, the theme of false and error is a third theoretical element common to the two dialogues, which, starting from Euthydemus, finds its solution in the Sophist. (shrink)

In hisMeditations, Marcus Aurelius repeatedly presents a disjunction between two conceptions of the natural world. Either the universe is ruled by providence or there are atoms. At 4.3, we find perhaps its most succinct statement: ἀνανεωσάμενος τὸ διεζευγμένον τό⋅ ἤτοι πρόνοια ἢ ἄτομοι (recall the disjunction: either providence or atoms). The formulation of the disjunction differs; at 7.32, being composed of atoms is contrasted with a stronger sort of unity (ἕνωσις) that may survive death. In 10.6 and 11.18 Marcus simply (...) offers φύσις (nature, construed in the Stoic manner as providentialist and causally efficacious) in opposition. On the surface, the contrast between the theory of atomism and the acceptance of providence seems to not warrant the term ‘disjunction’; it seems possible to accept both atomism and a causally determined providential universe. Yet, it is agreed on all sides, in the recent literature, that the relevant contrast for Marcus is not between the atomist and the non-atomist views of the constitution of the natural world as such but between two entailments that follow from the atomist Epicurean and the non-atomist Stoic advocacy of these positions. The contrast is between the providential ordering of the Stoic universe and the chaotic chance-ridden Epicurean model. (shrink)

The thesis offers a reconstruction of Plotinus' reading of the Theaetetus, and it presents an account of his epistemology that rests on that reading. It aims to show that Plotinus reads the Theaetetus as containing two anti-sceptical arguments. The first argument is an answer to radical scepticism, namely, to the thesis that nothing is apprehensible and judgement must be suspended on all matters. The second argument is an answer to a more moderate form of scepticism, which does not endorse a (...) universal suspension of judgement, but maintains nonetheless that scientific knowledge is unattainable.

The purpose of this paper is to identify the upholders of the thesis reported by Plutarch, De Stoicorum repugnantiis 23, aimed to reject Stoic determinism. A brief introduction will be devoted to the relationship between this text and the more general context of the Stoic philosophy. Then, I will take into account the objection against Stoic determinism raised by some anonymous philosophers: according to it, causal determinism would be inconsistent with the choice among indistinguishables. Chrysippus replied that if that choice (...) were not determined, it would occur without causes; and this would be absurd. Then I will summarize the most likely hypotheses about the identification of Chrysippus’ opponents, and I will opt for Academics. Finally, I will try to conjecture the link between Plutarch’s passage and the debate among Stoics and Academics about indistinguishables, as we know it from other sources. (shrink)

The Stoics’ way of presenting principles – the active and the passive – is ambiguous because they say that principles are two while also suggesting that they are inseparable and thus interdependent. This ambiguity cannot be resolved in favour of one or the other side of the dilemma, as is shown by analysis of two possible models of the relations among principles – a causal and a categories-based model. This ambiguity is rather a necessary consequence of the Stoic view of (...) principles and should be compared to the ambiguity of Plato’s concept of “principles” in the Timaeus. Plato’s Receptacle is in a similar relation to other constitutive elements of his cosmogonical account as are the two Stoic principles, each to the other. In particular, the relation between the Receptacle and qualities in it is to be seen as a systematic parallel to the relation of the Stoic principles (and probably also its historical model). The concluding claim is that Plato and the Stoics advance a similar kind of dualism which should be called such, despite its ambiguity. The ambiguity in both systems is due to the need to see the principles in such a relation as would reveal their dependence, and thus secure the basic unity of the cosmos. (shrink)
