Neologicists have sought to ground mathematical knowledge in abstraction. One especially obstinate problem for this account is the bad company problem. The leading neologicist strategy for resolving this problem is to attempt to sift the good abstraction principles from the bad. This response faces a dilemma: the system of ‘good’ abstraction principles either falls foul of the Scylla of inconsistency or the Charybdis of being unable to recover a modest portion of Zermelo–Fraenkel set theory with its intended generality. This article (...) argues that the bad company problem is due to the ‘static’ character of abstraction on the neologicist's account and develops a ‘dynamic’ account of abstraction that avoids both horns of the dilemma. 1 Introduction2ion Reconstructed3 From Bad to Worse4 Abstraction Reconceived5 Bad Company Made GoodA AppendixA.1SemanticsA.2LogicA.3ConsistencyA.4Strength.

We provide two programmatic frameworks for integrating philosophical research on understanding with complementary work in computer science, psychology, and neuroscience. First, philosophical theories of understanding have consequences about how agents should reason if they are to understand that can then be evaluated empirically by their concordance with findings in scientific studies of reasoning. Second, these studies use a multitude of explanations, and a philosophical theory of understanding is well suited to integrating these explanations in illuminating ways.

The paper shows a new example of nonuniqueness of the solutionto Newtonian equations of motion for infinite gravitational systems. Unlike otherexamples, the gravitational field presents no singularity, nor are the non-gravitational forcesintroduced in the model singular (in particular, there are no collisions). The result is also ofinterest because it points to an interesting limitation of the elementary (Newtonian) formulationof classical mechanics.

In this article I propose what I call the inverse spaceship paradox. The article's interest lies in the fact that, contrary to what appears to be an implicit agreement in the literature on indeterminism, it shows that coming from infinity can be a perfectly predictable and therefore deterministic process in a classical universe.

'Johann Sommerville's is an impeccable textbook. Simply written, it provides exposition of Hobbes' arguments in the context of English and continental thought'. P. Springborg, University of Sydney, Political Studies, Vol. XL1, No 2 6/93 Thomas Hobbes was probably the greatest of British political theorists. Too often commentators have failed to grasp his meaning because they have ignored the historical context in which he wrote. Drawing on much recent scholarship and on many little-known seventeenth century sources, this book presents a lucid (...) and jargon-free examination of Hobbes' arguments, setting them against a background of the ideas of his contemporaries and of the political events of his lifetime. By viewing Hobbes in his context, the book both clarifies his theories and illuminates European thinking at a critical stage in the development of modern political ideas. (shrink)

Despite Vancil’s (1979) proclamation over twenty years ago that topoi have been abandoned in argument theory, this essay contends that topoi should have a vital role in contemporary argumentation theory. Four key areas are identified where topoi are (or can be) essential tools for argumentation: Locating argument, building argument, development of critical thinking, and argument pedagogy. As a result, teachers and students of argument can both benefit from a (re)discovery of topoi.

The concept of civil society has once again emerged as a viable mechanism for developing and sustaining deliberative democracy. However, an essential component of many strategies to sustain civil society appears lacking, especially when we see the growing cynicism and apathy among citizens. What is missing is a strategy for training or encouraging citizens to participate more fully in civil society. The skills of advocacy can, at least in part, help renew civic activism. Thus, the role of advocacy will be (...) explored as a potential way to resuscitate civil society. (shrink)

The 2005 UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions provides an international policy lens for analysing broad debates on issues of cultural globalization and development. The interdisciplinary contributions in this volume offer a fresh understanding of these key issues whilst examining cultural globalization, which is conceived in terms of artistic expressions and entertainment industries and interpreted anthropologically as the rituals, symbols, and practices of everyday life. The broad gamut of theories, methods, and evidence collected (...) by the editors outlines UNESCO's accomplishments, shortcomings, and future policy prospects. This edited collection has a clear message: The Convention is a useful and important instrument in the debate on cultural diversity, but not broad enough or sufficient to confront major challenges concerning human rights, sustainability, and cultural diversity as a whole.

A wide variety of philosophers seem to agree that there is something dubious about the distinction between fact and value. This paper evaluates some of the arguments made for such a contention. It is argued that only the crudest form of pragmatism leads to a conflation of fact and value. Other arguments against the fact/value distinction, mostly drawn from Putnam's Reason, Truth and History, are examined in order to show that they are either false or trivial. S. Afr. J. Philos. (...)
