Truth of x (independently of any description of x) that it is f. A property f which holds of x but is not per se of x is said to hold per accidens of x. The essence of an individual is the sum of its per se properties. We can formulate the following: doctrine a: concrete individuals do not have essences though abstract entities do. Doctrine b: concrete individuals have essences but they do not individuate, whereas abstract entities have essences (...) which do individuate. Assumption i: we shall say that a thing exists insofar as it has an essence. Assumption ii: we shall say that we know a thing when we know what its per se properties are. We argue that plato held doctrine a and aristotle doctrine b (with assumptions i and ii). (edited). (shrink)

The Greater Alcibiades has been dismissed as spurious by a great many scholars including most of the major Platonists, and for a variety of reasons. Many of these reasons are to my mind extremely weak, and would apply with equal force to some of the undoubtedly genuine dialogues: Bluck has argued that nearly all can be met by supposing that Plato wrote it for some special purpose, for instance as a reply to Polycrates' attack on Socrates. It is noteworthy that (...) several scholars, while rejecting die work, do so with reluctance and a hint of misgiving. Shorey, for instance, sees touches worthy of Plato himself, and de Strycker thinks the work may actually have been revised by Plato. (shrink)

The goal of this paper is to examine the cognitive limits of aisthêsis in 184-6 of Plato’s Theaetetus. The options are: aisthêsis as ‘bare sensation’ and aisthêsis as ‘perceptual judgment’. I argue that Plato ignores the tension between these two alternatives because he is describing the whole process of perception as containing both. My focus is the text at 184-5, but first I make some preliminary comments, from a synoptic perspective, about what Plato is doing in the context of the (...) argument. After that, I move on the text, offering translations and interpretations of the relevant parts. I also discuss some of Cornford and Cooper’s ideas about Theaetetus 184-6. (shrink)

Any comprehensive interpretation of the "Theaetetus" has to provide answers to, among others, two very general questions concerning that dialogue: "What is Plato's relation to the problems faced in the "Theaetetus"?" and "What is the significance of the absence of the Forms from the discussion of the "Theaetetus", given their undoubted relevance to the topic of the dialogue, i.e. knowledge?" Predominantly, the answer given to the first question in the literature has been that the problems are those that Plato is (...) trying to tackle and the one to the second question, when it has been addressed at all, that the Forms are left out of the discussion because Plato no longer thought them relevant, either for having abandoned or seriously revised them, by the time of writing the "Theaetetus". In this study of the Wax Block and the Aviary models of judgment that occur in the second part of the "Theaetetus" as part of its discussion of the problem of false judgment, I argue that the problems faced there actually arise because of the neglect of Forms. The discussion of the second part is, I contend, carried out on a materialist ontology, an ontology assumed because it suits the definition of knowledge as true judgment which inaugurates that part of the dialogue, an ontology in no way subscribed to by Plato. The Wax Block is, I explain, a materialist model and fails in the case of judgments about numbers for treating them on a par with material subjects, ignoring their intelligible status. In particular, it fails to distinguish judging 5 and 7 to be 11 from judging 12 to be 11 because of its neglect of Forms; Plato would distinguish those judgments by distinguishing 5 and 7 from 12 with help from his part-whole analysis, to which the Forms are essential.

At 47e–53c of the Timaeus Plato presents his most detailed metaphysical analysis of particulars. We are told about the construction of the physical universe, the ways we can and cannot talk about the phenomena produced, and about the two causes – Necessity and Intelligence – which govern the processes and results of production. It seems to me that we are told too much and too little: too much, because we have two accounts of the generation of phenomenal particulars – one, (...) the ‘formal account’, which makes use of the receptacle, Forms and form-copies, and a second, the ‘geometrical account’, which appeals to geometrical shapes, the Demiurge and, apparently, matter; too little, because there is insufficient guidance as to how to relate the two accounts.

In the Timaeus, Plato’s Timaeus offers an account of the sensible world in terms of “images” of forms. Often, images are taken to be particulars: either objects or particular property instances (tropes). Contrary to this trend, I argue that images are general characteristics which are immanent in the receptacle, or bundles of such characteristics. Thus, the entire sensible world can be analysed in terms of immanent general characteristics, the receptacle, and forms. Hence, for Timaeus, fundamentally, there are no sensible particulars. (...) I end by arguing that my interpretation is compatible with Timaeus’ construction of sensible entities from triangles. (shrink)

This paper approaches the Critias straightforwardly as a work of political philosophy but gives greater attention to Athens’ opponent, Atlantis, whose founding, political organization, and eventual decline each offer important lessons about the aims of legislation and political life. I begin by comparing the foundation of the two cities as presented in Critias’ myth, with a special focus on the role of divine persuasion (I). I then describe the political organization of Athens and Atlantis, showing how they reflect the different (...) ways in which their founding gods exercised divine persuasion (II). Next, I focus on the decline of Atlantis and the causes behind it (III). Finally (IV), I discuss the lessons that I think can be gathered from the foregoing sections and show how the themes that emerge from the comparison of the two cities anticipate their more extensive exploration in the Laws.

La controversia en torno a la unidad del Parménides de Platón y al sentidode su primera parte continúa. El autor presenta una posible solución señalando la coincidencia de su estructura con el símil de la línea. Ello lo lleva a ubicar al joven Sócrates en el segmento correspondientea la óuivoux y al viejoParménides en el segmento de olc;. Como el que '"tiene inteligencia"de la verdad basado en su aprehensión del Uno-Bien, Parménides resulta siendo el representante de la areté del filósofo.

Plato's comments on astronomy and the education of the guardians at Republic 528e ff have been hotly disputed, and have provoked much criticism from those who have interpreted them as a rejection or denigration of observational astronomy. Here I argue that the key to interpreting these comments lies in the relationship between the conception of enquiry that is implicit in the epistemological allegories, and the programme for the education of the guardians that Plato subsequently proposes. We have, I suggest, been (...) too eager to stress the similarities here, when recognition of the differences may supply us with the tools required for a better understanding of 528e ff, one that to a large extent disarms the anti-empirical critique. My discussion proceeds in three stages. Firstly, Plato takes great care to place his comments on astronomy in the context of the preceding epistemological allegories. Is there any evidence here, where Plato might be thought to discuss enquiry in general, that he rejected or denigrated observation? I argue that even if Plato advocated a 'Two Worlds' (TW) ontology, he still envisaged a dynamic process of enquiry, interrelating sensibles and intelligibles, the investigation of each being necessary but not sufficient to achieve the overall aim. Secondly, Plato appears to be deriving how we ought to go about educating the guardians from how we ought to conduct our enquiries. While the two are intimately related there are important differences, recognition of which turns the supposed rejection of observation into an affirmation of the need for an initial empirical approach. I contend that this makes good sense of the internal structure of 528e ff, and of its relations to other parts of the Republic. Thirdly, I discuss the Republic in relation to the evidence offered by later works on the question of astronomy and observation, and raise the question of whether Plato's views on the imperfection of the sensible world necessarily lead to the denigration of careful and prolonged empirical work.

Few arguments from the past have stirred up as much interest as Aristotle’s “Third man” and not so many texts have received as much attention as its account in chapter 22 of the Sophistici elenchi. And yet, several issues about both remain highly controversial, starting from the very nature of the argument at stake and the exact signification of some of its features. The essay provides a close commentary of the text, dealing with its main difficulties and suggesting an overall (...) interpretation of Aristotle’s discussion of the “Third Man” argument. (shrink)

In this paper I discuss the problem of the meanings of the verb ‘be’ in Plato’s Timaeus. My claim is that, at least in that dialogue, existence emerges as the main and autonomous meaning of the verb ‘be’, contrary to the widespread view first defended in a series of studies by Charles Kahn according to which, in the Greek language and in Plato’s philosophy, the verb ‘be’ basically has a copulative-predicative and, more specifically, a truth-related meaning. I consider and examine (...) some passages from the Timaeus (27d5–28a4, 29b3–c3, 37e3–38b3, 51b7–52a7) where the concept of existence seems to be expressed in a clear and definite way by the use of the verb ‘be.’ I conclude by making some remarks on how we should understand the notion of existence, not least with reference to the problem of truth, within Plato’s philosophy and the Timaeus in particular.

Despite the fact that the theory of Forms is regarded as the hallmark of Plato’s philosophy, it has remained remarkably elusive, because it is more hinted at than explained in his dialogues. Given the uncertainty concerning the nature and extension of the Forms, this article makes no pretense to coming up with solutions to all problems that have occupied scholars since antiquity. It aims to elucidate only two aspects of that theory: the indication in certain dialogues that the Forms are (...) what in modern parlance are called functions or purposes, and the indication in other dialogues that such functions rely on harmonious structures.

On Malcolm Schofield’s highly influential reading of the Similarity Regress in Part I of the Parmenides, the problem that the Regress poses is explanatory. Socrates posited the Similarity Form in order to explain why similar things are similar: similar things are similar because they participate in the Form Similarity as copies of the same original. Yet, the Similarity Regress generates an infinite series of Similarity Forms such that explanation is deferred ad infinitum. Schofield provides a philosophical incentive for adopting his (...) reading. He argues that the treatment of similarity in Part II of the dialogue yields a complete explanation of similarity. If we adopt this account, we can avoid the Similarity Regress altogether since a Form of Similarity is not needed in order to explain why similar things are similar. Thus, his interpretation has a hugely important philosophical pay-off. However, there is a different way to read the argument. Socrates claims that each Form is only one. Yet, the Similarity Regress is an argument that generates an infinite series of Similarity Forms. This results in a violation of the principle of non-contradiction: there is both only one Similarity Form and infinitely many Similarity Forms. Yet, anything that is incompatible with the principle of non-contradiction is surely absurd. Nobody, as far as I am aware, has explored whether this reading also has philosophical pay-off if we look at it together with similarity in Part II. However, should this interpretation pay off, it would be a viable alternative to Schofield’s. In this paper, I explore both views in the context of the treatment of similarity in Part II of the Parmenides. I argue for an account of similarity that differs from Schofield’s. Although my account is not wholly dismissive of Schofield’s, it renders the pay-off of Schofield’s account less appealing than he suggests. Furthermore, I show that the account of similarity in Part II also yields important lessons for the proponent of the alternative reading of the Similarity Regress: similarity as treated in Part II simply leads to further infinite regresses, thereby pushing us to consider rejecting the account of similarity in Part II too and to look for some other account intead.

This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

Is there any relation between Plato’s political thinking and his cosmology – physical theory? If there is, how can it be outlined? Does the natural world constitute for Plato a leader thread, so that he can give shape to his ideal Republic (Politeia)? Which are the ratios that are shown? In which way does Plato derive ideas to form his political theory, through nature? Is the platonic state too much of an ideal to be considered utopian not only from philosophy (...) scholars, but also from the majority of people? Or is it, instead, absolutely consistent to the platonic cosmological prototype that the Athenian philosopher creates in Timaeus to explain creation and being? Why does Plato in his mainly cosmological work decide to dedicate a noteworthy part to speak, primarily, about the achievements of the city where he himself and all those who converse with him live? The above questions outline the framework of the present work, which aims to locate and underline the principal –in our opinion- developments in Plato’s political thinking, in Timaeus and the Laws. Timaeus is widely known because it is primarilt a complete – although tough in understanding- expression of Plato’s cosmological and cosmogenic perceptions. Laws, and in particular the 10th book we are concerned in the current study, offers –after Plato’s Republic- a new perspective of his concern about the citizen, the city, and politics. The parallel approach of these two platonic works aims to point out the close relation of Plato’s political thinking with the greater knowledge of the construction and function of the world, and to highlight the holisticity of platonic thought. --- Υπάρχει κάποια σχέση μεταξύ της πολιτικής θεωρίας του Πλάτωνα και της κοσμολογίας του – φυσικής θεωρίας; Αν ναι, πώς αυτή σκιαγραφείται; Συνιστά ο φυσικός κόσμος ένα οδηγητικό νήμα για τον Πλάτωνα, ώστε να διαμορφώσει την ιδανική πολιτεία; Ποιες είναι οι αναλογίες που προκύπτουν; Με ποιο τρόπο ο Πλάτωνας αντλεί μέσω της φύσης ιδέες για την διαμόρφωση της πολιτικής του θεωρίας; Πώς αντιστοιχούν οι ιδέες αυτές στον πολιτικό δέον γενέσθαι; Είναι η πλατωνική πολιτεία τόσο ιδανική ώστε πολλοί μελετητές της φιλοσοφίας αλλά και μεγάλη πλειοψηφία ανθρώπων να τη θεωρούν ουτοπική, ή, αντίθετα, είναι απόλυτα συνεπής προς το κοσμολογικό πρότυπο που διαμορφώνει ο Αθηναίος φιλόσοφος στον Τίμαιο, για να εξηγήσει τη δημιουργία και την ύπαρξη; Γιατί στο κατεξοχήν κοσμολογικό αυτό έργο του, ο Πλάτων επιλέγει να αφιερώσει υπολογίσιμο τμήμα του για να μιλήσει καταρχήν για τα κατορθώματα της πόλης στην οποία ζει ο ίδιος και όσοι συνδιαλέγονται μαζί του; Τα ανωτέρω ερωτήματα προσδιορίζουν το πλαίσιο στο οποίο κινείται η παρούσα εργασία, η οποία έχει σκοπό να εντοπίσει και να επισημάνει τα κυριότερα –κατά τη γνώμη μας- σημεία του Τιμαίου και των Νόμων, στα οποία αναπτύσσεται η πολιτική σκέψη του Πλάτωνα. Ο Τίμαιος είναι έργο ευρύτατα γνωστό κυρίως διότι συνιστά την πλήρη -αν και δυσνόητη- έκφραση των κοσμολογικών και κοσμογονικών αντιλήψεων του Πλάτωνα. Οι Νόμοι, και ιδιαίτερα το 10ο βιβλίο που μας απασχολεί στην παρούσα μελέτη, συνιστούν μια εκ νέου –μετά την Πολιτεία- έκφραση της έγνοιας του Πλάτωνα για τον πολίτη, την πόλη και την πολιτική. Η παράλληλη θεώρηση των δύο αυτών πλατωνικών έργων στοχεύει στο να επισημάνει την στενή σχέση της πλατωνικής πολιτικής σκέψης με την ευρύτερη γνώση της κατασκευής και λειτουργίας του κόσμου, και να αναδείξει την ολιστικότητα της πλατωνικής σκέψης.
