De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

A recent article on ‘The Number of Speaking Actors in Old Comedy’ by D. M. MacDowell has argued that to perform the plays of Aristophanes required the use of four, but never five, speaking actors.1 Systematically argued, MacDowell presents a cogent case against Henderson , who has suggested that at times five actors were permitted. MacDowell also presents some very sensible observations on the nature of any prescription which might limit the number of actors. The final paragraphs, however, express considerable (...) discomfort at the earliest work in the extant corpus: 'Akharnians, however, remains problematic, since it has two scenes which may be thought to require five actors' . A tentative solution is offered by MacDowell, which is that 'these scenes were actually performed without a fifth actor, by making very quick changes in the scene with Amphitheos and the Envoy, and by using dolls for the Megarian's Daughters' . Unspeaking performers for the Megarian's Daughters are more likely than dolls, since they must follow orders for movement . Apart from this, I have no doubt that this is indeed how Akharnians was performed, and an examination of the specific comic techniques employed by Aristophanes in the two problematic scenes in Akharnians demonstrates not only the comic desirability of their use, but their applicability to other plays by Aristophanes.

In this paper we will show that Hempel's covering law model can't deal very well with explanations that are based on incomplete knowledge. In particular the symmetry thesis, which is an important aspect of the covering law model, turns out to be problematic for these explanations. We will discuss an example of an electric circuit, which clearly indicates that the symmetry of explanation and prediction does not always hold. It will be argued that an alternative logic for causal explanation is (...) needed. And we will investigate to what extent non-monotonic epistemic logic can provide such an alternative logical framework. Finally we will show that our non-monotonic logical analysis of explanation is not only suitable for simple cases such as the electric circuit, but that it also sheds new light on more controversial causal explanations such as Milton Friedman's explanation of the business cycle.

This volume, which is part of the Clarendon Aristotle Series, offers a clear and faithful new translation of Books II to IV of Aristotle's Nicomachean Ethics, accompanied by an analytical commentary focusing on philosophical issues. In Books II to IV, Aristotle gives his account of virtue of character in general and of the principal virtues individually, topics of central interest both to his ethical theory and to modern ethical theorists. Consequently major themes of the commentary are connections on the one (...) hand with other relevant Aristotelian texts and on the other with modern writings, both text-related and thematic. -/- Since the main aim of the volume is to make Aristotle's thought as accessible as possible to readers who do not know Greek, considerable care is taken to elucidate both his technical vocabulary and significant features of his Greek idiom. C. C. W. Taylor also provides systematic comparisons with other translations into English and other languages, and frequent references to other commentaries, ancient, medieval, and modern. These features make the work useful to other scholars in the field as well as to students of philosophy, both undergraduate and graduate. -/- In view of the widespread contemporary interest in the topic of virtue, the volume should appeal to students of ethics (even those hitherto unacquainted with ancient thought) and to any reader who is concerned to see how fundamental questions of life and conduct were approached in a culture significantly different from our own.

This essay explores the treatment of the relation between nature (phusis) and norm or convention (nomos) in Democritus and in certain Platonic dialogues. In his physical theory Democritus draws a sharp contrast between the real nature of things and their representation via human conventions, but in his political and ethical theory he maintains that moral conventions are grounded in the reality of human nature. Plato builds on that insight in the account of the nature of morality in the myth in (...) the Protagoras. That provides material for a defense of morality against the attacks by Callicles in the Gorgias and Thrasymachus and Glaucon in the Republic, all of whom seek to use the nature-convention contrast to devalue morality.

197: on logon didonai as giving a proof. In answer to Plato's charge that mathematicians take as their starting point certain unproved assumptions, and call upon them to "give an account" of them in the sense of deriving them from some more basic principle or principles.

Education is so strongly emphasized in the Chinese culture that academic success is widely regarded as the only indicator of success, while too much physical activity is often discouraged because it drains energy and affects academic concentration. This study investigated the relations among academic achievement, self?esteem, school conduct and physical activity level. The participants were 333 Chinese pre?adolescents (aged 8?12) in Hong Kong. Examination results and conduct grades were obtained from the school records. Global self?esteem was measured with the Physical (...) self?description questionnaire (PSDQ), while physical activity patterns of the children were assessed with the Physical activity questionnaire for children (PAQ?C). Results showed that high academic achievers consistently attained better school conduct marks. However, physical activity level was quite an independent entity that was related neither to academic achievement nor school conduct. Furthermore, regression analyses showed that only academically high?achieving boys and physically active boys had higher self?esteem. (shrink)

In this dialogue Plato shows the pretensions of the leading sophist, Protagoras, challenged by the critical arguments of Socrates. The dialogue broadens out to consider the nature of the good life and the role of intellect and pleasure.

C. C. W. Taylor presents a selection of his essays in ancient philosophy, drawn from forty years of writings on the subject. The central theme of the volume is the moral psychology of Plato and Aristotle, with a special focus on pleasure and related concepts, an area central to Greek ethical thought. Taylor also discusses Socrates and the Greek atomists, showing how Plato's ethics grows out of the thought of Socrates, and that pleasure is also a central concept for the (...) atomists. Pleasure, Mind, and Soul provides a fascinating survey of a range of important topics in the work of some of the greatest ancient philosophers, and which remain the subject of lively philosophical debate today.

Davidson poses the problem via three propositions p1-P3, Each persuasive but apparently inconsistent. His solution, That the three are consistent, Merely re-Phrases the problem. We should rather reject p2; if an agent judges that it would be better to do "x" than to do "y", Then he wants to do "x" more than he wants to do "y". Plato accepts p2 because he thinks all agents predominantly self-Interested, And hare because he thinks that evaluative judgments imply desires; both are criticized. (...) An alternative to p2, Consistent with p1 and p3, Makes a subtler connection between judgment, Desire and behaviour. (shrink)

While claiming to refute locke's theory of abstract ideas, Berkeley himself accepts a form of abstractionism. Locke's account of abstraction is indeterminate between two doctrines: 1) abstract ideas are representations of paradigm instances of kinds, 2) abstract ideas are schematic representations of the defining features of kinds. Berkeley's arguments are directed exclusively against 2, And refute only a specific version of it, Which there is no reason to ascribe to locke; berkeley himself accepts abstract ideas of the former type. Locke's (...) theory suffers from circularity and redundancy, Berkeley's from conflation of thought with imagination. (shrink)
