Towards the close of Book V of theRepublicPlato tells us that the true philosopher has knowledge and that the objects of knowledge are the Forms. By contrast, the ‘lovers of sights and sounds’, he tells us, have no more than belief, the objects of which are physical particulars. He then goes on to present us with some very radical-sounding assertions about the nature of these physical particulars. They are bearers of opposite properties, he says, in so thorough-going a manner that (...) we cannot say of them that they are nor that they are not: they lie somewhere between being and utter non-being.This passage of theRepublic still awaits an agreed interpretation and I want to suggest as a reason for this that it is usually interpreted in isolation. I will argue that it becomes easier to understand when seen against the background of Plato's developing thought. To be more precise, it makes sense when taken as a rejection by Plato of one of his earlier beliefs: namely, a doctrine of essentialism to be found in thePhaedo.The greater part of this paper then will be an attempt to show thatRepublicV is a rejection of thePhaedo'sdoctrine of essences. Its concluding part will try to explain why that doctrine was rejected. (shrink)

This paper provides a new interpretation of Plato’s account of justice as psychic health in Republic IV. It argues that what has traditionally been considered to be one single analogy is actually a more complex line of reasoning that contains various medical analogies. These medical analogies are not only different in number but also in kind. I discuss each of them separately, while providing a response to various objections.

Much has been made of Plato's influence of medieval minds, yet as Raymond Klibansky reminds us, much remains to be learned. The twelfth-century Platonist writings are notably various: Brian Stock and Winthrop Weatherbee have examined the effect of Platonic tradition on twelfth-century poetry and Tullio Gregory and Richard Lemay have added to our understanding of its effect on philosophical and theoretical thought in this period. The rich accretions of Hermetic and astrological material have been studied along with the older Plotinian (...) interpretations and the whole complicated orchestration of these various themes has received minute attention. Moreover, in this diversity of Platonic writings, a strongly imaginative quality is often present. Indeed, as Peter Dronke says,They are achievements not only of the rational intellect but of the active imagination. Their cosmological insights are nourished by imaginative springs as much as by the disciplined sources of abstract thinking. Theirs is a realm where sacred visions and profane myth can combine with analytic thought, poetic fantasy with physical and metaphysical speculation. In terms of scholarship it is a realm which, because it is at the borders of several genres, is still in many ways a neglected one. (shrink)

In Plato’s Statesman, the Eleatic Stranger leads Socrates the Younger and their audience through an analysis of the statesman in the service of the interlocutors’ becoming “more capable in dialectic regarding all things”. In this way, the dialectical exercise in the text is both intrinsically and instrumentally valuable, as it yields a philosophically rigorous account of statesmanship and exhibits a method of dialectical inquiry. After the series of bifurcatory divisions in the Sophist and early Statesman, the Stranger changes to a (...) non-bifurcatory method of dividing to account for the statesman, but does not explain the reason for this change. I argue that the change is prepared by the elements discussed in the digression from 277a2 to 287b2. Here the Stranger makes use of four concepts that are crucial for understanding this change: the notion of paradigm, the paradigms of care and the weaver, and the notion of due measure. I claim that the notion of paradigm clarifies the nature of dialectical inquiry, care and weaving act as paradigms appropriate to dialectical practice, and an account of due measure offers insight into the constitutive ratios that govern the structuring of kinds pursued through dialectical inquiry. I suggest that the non-bifurcatory method is intended to articulate knowledge in the strictest sense, or knowledge of the forms, presenting a method of inquiry into being and its structure that will foster the turning of the soul from things to forms that Socrates describes in the Republic.

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.

It is arguable that the student of the deductions which make up the second part of Plato's Parmenides is today better placed than any of his predecessors, save Aristotle, Speusippus, and other immediate associates of Plato, to understand and evaluate those forbidding pages. Ways of looking at and handling the matter of the text are available to him which were not open to those who lived before the rise of critical philological scholarship in Europe in the last century, and of (...) analytical philosophy in the English-speaking world in this. He has to hand, too, some pioneering work on the dialogue of recent date. (shrink)

The eschatological myth in the tenth book of the Laws contains a paragraph which purports to explain why, in the next world, efficient treatmentof souls according to their deserts is ‘marvellously easy’.

This paper defends Plotinus’ reading ofSophist248e-249d as an expression of the togetherness or unity-in-duality of intellect and intelligible being. Throughout the dialogues Plato consistently presents knowledge as a togetherness of knower and known, expressing this through the myth of recollection and through metaphors of grasping, eating, and sexual union. He indicates that an intelligible paradigm is in the thought that apprehends it, and regularly regards the forms not as extrinsic “objects” but as the contents of living intelligence. A meticulous reading (...) ofSophist248e-249d shows that the “motion” attributed to intelligible being is not temporal change but the activity of intellectual apprehension. Aristotle’s doctrines of knowledge as identity of intellect and the intelligible, and of divine intellect as thinking itself, are therefore in continuity with Plato, and Plotinus’ doctrine of intellect and being is continuous with both Plato and Aristotle.

The paper addresses the following question: why do human beings, on Aristotle’s view, have an innate tendency to badness, that is, to developing desires that go beyond, and often against, their natural needs? Given Aristotle’s teleological assumptions (including the thesis that nature does nothing in vain), such tendency should not be present. I argue that the culprit is to be found in the workings of rationality. In particular, it is the presence of theoretical reason that necessitates the limitless nature of (...) human non-rational desires. (shrink)

The standard interpretation of "Theaetetus" 152-160 has Plato attribute to Protagoras a relativistic theory of truth and existence. It is argued here that in fact the individuals of Protagorean worlds are inter-Personal. (thus the Protagorean theory has public objects, but private truth). Also, a new interpretation is offered of Plato's use of heraclitean flux to model relativism. The philosophical and semantic consequences of the interpretation are explored.

The Cratylus begins with a paradox; it ends with a paradox; and it has a paradox in between. But this disturbing characteristic of the dialogue has been overshadowed, not to say ignored, in the literature. For commentators have seen it as their task to discover exactly what theory of language Plato himself, despite his declared perplexity, intends to adopt as he rejects the alternatives of Hermogenes and Cratylus. A common view, then, has been to suppose that the πορίαι of the (...) dialogue are mere camouflage for the hidden dogma, whatever that may be. A favoured candidate, of course, has been the theory of transcendent forms, in some preliminary version. As a consequence, the dialogue has often been seen as a precursor to the great metaphysical works of Plato's middle period such as the Phaedo or the Republic. Not so, I shall argue. My case is that this dialogue centres upon a series of paradoxes which are both powerful and unsettling. Their final effect is to attack the theory of forms, not to defend it. They are, I suggest, genuine proposals of philosophical difficulty, rather than mere artifice to disguise an idealist truth. As such, they belong, and may clearly be seen to belong, with works of the critical period which subject the theory of forms to scrutiny. Thus the πορίαι of the Cratylus have their counterparts in the Parmenides, the Theaetetus and the Sophist. I propose, then, that the dialogue was written during the late, critical period of Plato's philosophical activity. (shrink)

In recent years considerable attention has been focused on the question whether Plato ever uses arguments he knows to be sophistical, especially whether he puts such arguments into the mouth of Socrates. Though differing views have been held, at the present time the majority of scholars seem to believe that Plato does not. Though I disagree with this position, I will not attack it directly in this paper. Instead I will discuss what I take to be an important preliminary matter, (...) establishing criteria that can be employed in order to assess the claim that one of Plato's characters does or does not argue sophistically. Since the case of Socrates is by far the most important, I will limit discussion here to the question whether Socrates ever uses sophistry. (shrink)

The death of Socrates gave birth to an industry of biographical literature which often took the form of a defence or prosecution , sometimes purporting to be the actual defence or prosecution conducted at his trial. Plato and Xenophon wrote works in his defence. Among his critics, one Polycrates had a certain notoriety. Lysias, Theodectes and Demetrius of Phalerum, orators and rhetoricians like Polycrates, were credited with further works of apology. There were doubtless many others. The aim of this paper (...) is to show that Xenophon wrote his Defence in the light of the rhetorical theory that required that a speaker utter words and thoughts appropriate πρεποντα to his character.

The argument in theProtagoraswhich starts with an analysis of giving in to pleasure in terms of ignorance, and leads into a demonstration that courage is knowledge, is certainly one of the most brilliant in Plato and equally certainly one of the trickiest. My discussion deals mainly with three problems: Precisely what absurdity is detected in the popular account of moral weakness, and where is it located in the text? On the basis of largely formal considerations I believe that the absurdity (...) is a much less subtle affair than has been thought, and that it is located at 355c-d. What is the connection between knowledge and belief in 358b-d, and how do these two concepts figure in the arguments which precede and follow this passage? Here I want to comment on differences between theProtagorasand other Socratic arguments. How good is the argument at 356–357e which analyses moral weakness as ignorance? There are several problems here, including a fundamental puzzle of the dialogue, namely that, apparently, Plato uses a non-Socratic hedonism to establish the Socratic thesis that virtue is knowledge. Here I agree with those critics who see irony at the expense of the sophists—sophistic teaching is shown to be grounded in hedonism—but in addition I suggest that Plato also offers an oblique criticism of hedonism itself in the course of which basic points of real substance are made. This interpretation fits in with various other features of the dialogue, including the curious fact that, though the main argument proceeds on a thorough-going hedonistic basis, Socrates is subtly but distinctly not committed to that basis. Hence the unity of the dialogue is supported, and as well an attitude to hedonism is given which is more consistent with that of other dialogues, while we are able to see the Socratic paradox in its regular role as a tool of ethical exploration.

Such is John Stuart Mill's succinct exposition of the core of utilitarian theory. A contemporary philosopher has aptly described utilitarianism as ‘the combination of two principles: the consequentialist principle that the rightness, or wrongness, of an action is determined by the goodness, or badness, of the results that flow from it and the hedonist principle that the only thing that is good in itself is pleasure and the only thing bad in itself is pain. Although the consequentialistprinciple has attracted the (...) most attention in modern discussions of utilitarianism, it is the second principle which invites immediate comparison with the views of Plato. I propose therefore to start by comparing the Platonic and the utilitarian conceptions of the good in the hope that this will enable us to see too in what sense Plato's position is consequentialist, and whether his ethical and political theories in general can properly be described as utilitarian.

There are two basic ways in which the phenomenon of learning is explicated in the Platonic dialogues: First, by means of an analogy with vision, and second, by arguing that the acquisition of knowledge is really anamnesis. The analogy with vision is the more common of the two and occurs throughout the dialogues. The passage in the Republic comparing the sun and the good is the best known instance of this approach to the clarification of learning. The basic point of (...) this explication is that the mind, like the eye, in order to discover truth must be turned in the right direction and be trained to apprehend and distinguish the characters of the objects it beholds. In this context, the acquisition of knowledge is clearly a discovery of that which was not previously known, just as the man who escapes from the cave sees what he had not previously seen, and at the end of the ascent of the heavenly ladder one “begins to see” what he has not seen before.

I argue that Plato believes that the soul must be both the principle of motion and the subject of cognition because it moves things specifically by means of its thoughts. I begin by arguing that the soul moves things by means of such acts as examination and deliberation, and that this view is developed in response to Anaxagoras. I then argue that every kind of soul enjoys a kind of cognition, with even plant souls having a form of Aristotelian discrimination (...) (krisis), and that there is therefore no completely unintelligent, evil soul in the cosmos that can explain disorderly motions; as a result, the soul is not the principle of all motion but only motion in the cosmos after it has been ordered by the Demiurge.

The question contrasts two ways of expressing the role of the sense organ in perception. In one the expression referring to the sense organ is put into the dative case ; the other is a construction with the preposition δiá governing the genitive case of the word for the sense organ.

David Furley has suggested that we think of Callicles’ immoralism as attacking a thick concept. I take up this suggestion and apply it to the argument of Plato’s Gorgias more generally. I show that the discussion between Socrates, Gorgias and Polus, which prepares the ground for Callicles, is precisely addressing the thickness of the concept of justice: it reveals that this concept is both descriptive and evaluative and that formulating a revisionist position about justice is therefore extremely difficult. Callicles’ strategy (...) is best read as a response to this difficulty, which sets the stage for Socrates’ revisionist account of justice. (shrink)

Plato’s tripartite soul plays a central role in his account of justice in the Republic. It thus comes as a surprise to find him apparently abandoning this model at the end of the work, when he suggests that the soul, as immortal, must be simple. I propose a way of reconciling these claims, appealing to neglected features of the city-soul analogy and the argument for the soul’s division. The original true soul, I argue, is partitioned, but in a finer manner (...) than how we encounter it in our everyday lives. (shrink)

I advocate an ad hominem reading of the hedonism that appears in the final argument of the Protagoras. I that attribute hedonism both to the Many and to Protagoras, but my focus is on the latter. I argue that the Protagoras in various ways reflects Plato’s view that the sophist is an inevitable advocate for, and himself implicitly inclined toward, hedonism, and I show that the text aims through that characterization to undermine Protagoras’ status as an educator. One of my (...) objectives in the course of my arguments is to explore connections between the final argument of the Protagoras and the Man-Measure Doctrine as it is developed in the Theaetetus.
