La exposición y crítica de las doctrinas antiguas tiene un lugar importante en los escritos de Aristóteles. Sin embargo, ciertas dudas se han vuelto corrientes acerca de la confiabilidad de sus descripciones. Más aún, se ha sostenido que Aristóteles deforma la comprensión histórica a través de la introducción de conceptos y términos propios. En este libro se aborda el problema a través de un análisis de las críticas que Aristóteles dirige a la teoría platónica de las Ideas, que permite explicar (...) la constitución y desarrollo de importantes conceptos aristotélicos a partir de la confrontación dialéctica con las doctrinas de su maestro. En efecto, las dificultades genuinas que Aristóteles descubre en el platonismo constituyen el motor para gestar nuevos conceptos, que no son ajenos, sino que surgen como implicaciones del examen crítico. Así, la imposición de términos propios no debe interpretarse como distorsión, sino como el modo que Aristóteles adopta para exhibir su particular solución a los problemas que los filósofos anteriores dejaron sin solución.

I argue that musical education in Plato’sRepublicis not aimed at developing a moral discriminatory faculty in the spirited part, but rather that its benefits are predominantly intellectual, and become fully apparent only at the philosophical stage of the guardians’ education. In order to prove this point, I discuss the intellectual state which the guardians’ philosophical education is meant to bring about, and then show why it is dependent on the earlier cognitive effects of musical education. Ultimately, I show that musical (...) education allows guardians to provide a unified analysis of both culture and nature. (shrink)

In Republic 4, Plato’s Socrates argues that there are three elements in the soul: the rational, the spirited, and the appetitive. This paper focuses on the argument distinguishing spirit from appetite in the story of Leontius. I shall argue that the rational element first opposes Leontius’ appetite and, when appetite overpowers reason, then Leontius’ spirited part opposes the appetitive. Consequently, there is a kind of disgust that would be appropriately characterized as rational; and, drawing on this consequence, I suggest that (...) the primary target of early ethical education is the rational element of the soul.

In this paper I explore a famous part of Plato’s Theaetetus where Socrates develops various models of the mind (picturing it first as a wax tablet and then as an aviary full of specimen birds). These are to solve some puzzles about how it is possible to make a mistake. On my interpretation, defended here, the discussion of mistakes is no digression, but is part of the refutation of Theaetetus’s thesis that knowledge is “true doxa”. It reveals that false doxa (...) is possible only if there is a certain stock of abstract knowledge, conceptual knowledge, that is not awareness of the particular individual that is being described. The individual must be identified under some description, or seen as something of a certain kind. Error can only occur if the description applied misdescribes the situation, but then if it is to be applied falsely it must first have been known from somewhere else. So knowledge cannot be reduced to the application of descriptions to particulars, but is to be found in the prior possession of abstract descriptions that can be deployed in identifying particular individuals on the ground.

What does Plato mean in saying that, for all forms, “F-ness is F”? In such claims, I argue, ‘F’ is being used metonymically to refer to the property of being productive of F-ness rather than to the property of being F, in a way consistent with univocity and the rejection of a genuine Self-Predication Assumption. I explain and defend this productive metonymy reading and show how it can resolve the troubling argument at Phaedo 74b7-c6.

At 252e1 to 253c9 in Plato’s Sophist, the Eleatic Visitor explains why philosophy is a science. Like the art of grammar, philosophical knowledge corresponds to a generic structure of discrete kinds and is acquired by systematic analysis of how these kinds intermingle. In the literature, the Visitor’s science is either understood as an expression of a mature and authentic platonic metaphysics, or as a sophisticated illusion staged to illustrate the seductive lure of sophistic deception. By showing how the Visitor’s account (...) of the science of philosophy is just as comprehensive, phantasmatic and self-concealing as the art of sophistry identified at the dialogue’s outset, this paper argues in favor of the latter view.

In Plato's Cratylus, Hermogenes contends that the correctness of names is conventional. Appealing though this claim sounds to modern ears, it does not meet with approval in the Cratylus. Why? I argue that the conventionalism promoted by Hermogenes is discredited by unacceptable relativist implications because it incorporates the mistaken assumption that correct names are individuated exclusively by their phonetic composition.

But if reason has no original influence, it is impossible it can withstand any principle which has such an efficacy, or ever keep the mind in suspense a moment. Thus, it appears, that the principle which opposes our passions cannot be the same with reason, and is only called so in an improper sense. We speak not strictly and philosophically, when we talk of the combat of passion and of reason.

We discuss the one–many problem as it appears in the Philebus and find that it is not restricted to the usually understood problem about the identity of universals across particulars that instantiate them (the Hylomorphic Dispersal Problem). In fact some of the most interesting aspects of the problem occur purely with respect to the relationship between Forms. We argue that contemporary metaphysicians may draw from the Philebus at least three different one–many relationships between universals themselves: instantiation, subkind and part, and (...) thereby construct three new ‘problems of the one and the many’ (an Eidetic Dispersal Problem, a Genus–Species Problem, and an Eidetic Combination Problem), which are as problematic as the version generally discussed. We then argue that this taxonomy sheds new and interesting light on certain discussions of higher-order universals in recent Australian analytic philosophy. (shrink)

The version of the paradox of false judgement examined at Tht. 188c10–189b9 relies on the assumption that to judge falsehoods is to judge the things which are not. The presentation of the argument displays several syntactic ambiguities: at several points it allows the reader to adopt different syntactic connections between the components of sentences. For instance, when Socrates says that in a false judgement the cognizer is “he who judges the things which are not about anything whatsoever” (188d3–4), how should (...) the clause “about anything whatsoever” be construed? In common with “he who judges” and “the things which are not” (in which case the cognizer would be “he who judges about anything whatsoever the things which are not about it”), or exclusively with “he who judges” (in which case the cognizer would be “he who judges about anything whatsoever the things which are not”)? The most plausible answer is that both construals are envisaged. Accordingly, the argument has two branches corresponding to these two alternative construals. In particular, it attempts to show that in both cases the cognizer will address what does not exist – an impossibility. The idea that a false judgement is concerned with what is not about its reference has a clear echo in the Sophist. The way in which the problem is handled in the Theaetetus provides a hint that can help to find a solution for the hotly debated issue of the interpretation of the Sophist’s account of false statement.

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.

This paper considers the use that Plato makes of the Principle of Non-Contradiction in his engagements with eristic refutations. By examining Plato’s use of the principle in his most detailed engagements with eristic—in the Sophist, the discussion of “agonistic” argumentation in the Theaetetus, and especially the Euthydemus—I aim to show that the pressure exerted on Plato by eristic refutations played a crucial role in his development of the PNC, and that the principle provided him with a much more sophisticated means (...) of demarcating philosophical argumentation from eristic than he is generally thought to have. In particular, I argue that Plato’s qualified formulation of the PNC restricts the class of genuine contradictions in such a way that reveals the contradictions that eristics produce through their refutations to be merely apparent and that Plato consistently appeals to his qualified conception of genuine contradiction in his encounters with eristics in order to demonstrate that their refutations are merely apparent. The paper concludes by suggesting that the conception of genuine contradiction afforded by the PNC did not just provide Plato with a way of demarcating genuine from eristic refutations, but also with an answer to substantive philosophical challenges that eristics raised through their refutations.

This dissertation is a study of the relation between Aristotle’s ethics and the crafts (or technai). My thesis is that Aristotle’s argument is at key points shaped by models proper to the crafts, this shaping being deeper than is generally acknowledged, and philosophically more problematic. Despite this, I conclude that the arguments I examine can, if revised, be upheld. The plan of the dissertation is as follows – Preface: The relation of my study to the extant secondary literature; Introduction: The (...) pre-Platonic concept of technē, as evidenced in Greek philosophical and literary sources, in particular the early Hippocratic corpus; Chapter one: The Platonic concept of technē, followed by an investigation of whether Plato affirms a virtue-technē in the Protagoras and Republic; Chapter two: Aristotle’s concept of technē, followed by scrutiny of his arguments in NE VI.5 against a virtue-technē, and of his analyses of slavery and deliberation; Chapter three: An exposition of Aristotle’s function argument, followed by a dominantist interpretation of it, and an explanation of dominantism as in part a technē-influenced doctrine; Chapter four: An examination of Aristotle’s ethical mean and its problems, with a diagnosis of these in terms of influence by the Philebus, and by paradigms derived from the crafts; Chapter five: Argument that Aristotle’s theory of habituation suffers from two significant opacities, these being a function of influence both by the Republic, and by models of craft-learning; Conclusion: Response to key objection; Aristotle’s ethics revised, defended.
