This book traces the development of formal logic from its origins in ancient Greece to the present day. The authors first discuss the work of logicians from Aristotle to Frege, showing how they were influenced by the philosophical or mathematical ideas of their time. They then examine developments in the present century.

Aristotle's treatise De Interpretatione is one of his central works; it continues to be the focus of much attention and debate. 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, basing this view upon a detailed chapter-by-chapter analysis.By treating the work systematically, rather than concentrating on certain selected passages, Whitaker is able to show that, contrary to traditional opinion, it forms (...) an organized and coherent whole. He argues that the De Interpretatione is intended to provide the underpinning for dialectic, the system of argument by question and answer set out in Aristotle's Topics; and he rejects the traditional view that the De Interpretatione concerns the assertion and is oriented towards the formal logic of the Prior Analytics. In doing so, he sheds valuable new light on some of Aristotle's most famous texts. (shrink)

The attempt to understand and develop Plato's philosophical views has a long history, starting with Aristotle and Plato's institutional successors in the academy towards the end of the fourth century bc. This article traces the history and development of the idea of Platonism. The development of a specifically Platonic philosophy took place mainly within the academy. As a result, the idea that Plato's dialogues already presented a well defined, comprehensive, and essentially correct philosophical system seems not to have arisen until (...) the first century bc. And it was probably not until toward the beginning of the second century ad that a disparate set of philosophers who identified themselves as “Platonists” conceived the project of advocating and defending a specifically Platonic philosophy of this kind by systematically interpreting and explaining Plato's texts.

The eleven papers comprising this book were read at two Bergson Centennial celebrations in 1959--at Hollins College and in Paris. From Pelikan's discussion of Bergson's place in theology to Merleau-Ponty's account of his view of history, the contributions lay bare many more enigmas in Bergson's relation to subsequent thought than they solve. Starkie's paper on the literary merits and impact of the work of Bergson makes such a compelling case for its kinship to Symbolism and Proust that one is tempted (...) to accept the thesis that the Bergsonian Heritage is most alive in those who are not philosophers. Contains a bibliography of books and articles by and on Bergson.--W. H. C. (shrink)

As a drama and a poem theEumenidesis often regarded with unease. It brings theOresteiato a conclusion; but its account of Athens and the Areopagus seems to many readers inspired more by patriotism than a sense of dramatic unity. Hence much attention has been devoted to Aeschylus' supposed political message in the play; as a result, the question of its fitness to crown the trilogy recedes into the background or even vanishes. On the other hand, those whose concern is with Aeschylus' (...) poetry tend to ignore his ‘politics’. The purpose of this paper is twofold. First, it seeks to vindicate Aeschylus the artist: to show, that is, how the founding of the homicide court and the cult of the Semnai on the Areopagus in Athens properly marks the end of the troubles of the Argive Atridae, and how the sufferings and guilt of individual men and women are resolved in a city's institutions. In pursuing this aim, it also has to consider, and try to define, the relation of the tragedian to his audience and to contemporary society. My concern, then, is with the individual and the community, both within the play and behind it. (shrink)

The most perplexing aspect of Galileo's work in physics is without doubt the sharp distinction one can draw between his essentially dynamic studies in such juvenilia as De Motu and the consciously kinematical approach of his later output—particularly the Two New Sciences. Whether one chooses to call this a shift from the “why” of motion to the “how”, or, as I should prefer, a shift from dynamics to kinematics, there can be no denying its existence. The Galileo who wrote that (...) “The present does not seem to be the proper time to investigate the cause of the acceleration of natural motion …” is, on the face of it, a very different man from the one who had earlier written almost an entire treatise on precisely this topic.

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)
