The concept of an attractor in a mathematical dynamical system is reviewed. Emphasis is placed on the distinction between a cell assembly, the corresponding attractor, and the attractor dynamics. The biological significance of these entities is discussed, especially the question of whether the representation of the stimulus requires the full attractor dynamics, or merely the cell assembly as a set of reverberating neurons. Comparison is made to Freeman's study of dynamic patterns in olfaction.

Lost in the debate over the use of racial and ethnic categories in biomedical research is community-level analysis of how these categories function and influence health. Such analysis offers a powerful critique of national and transnational categories usually used in biomedical research such as “African-American” and “Native American.” Ethnographic research on local African-American and Native American communities in Oklahoma shows the importance of community-level analysis. Local health practices tend to be shared by members of an everyday interactional community without regard (...) to racial or ethnic identity. Externally created practices tend to be based on the existence of externally-imposed racial or ethnic identities, but African-American and Native American community members show similar patterns in their use of extra-community practices. Thus, membership in an interactional community seems more important than externallyimposed racial or ethnic identity in determining local health practices, while class may be as or more important in accounting for extra-community practices.

Research on human genetic variation can present collective risks to all members of a socially identifiable group. Research that associates race or ethnicity with a genetic disposition to disease, for example, presents risks of group discrimination and stigmatization. To better protect against these risks, some have proposed supplemental community-based reviews of research on genetic differences between populations. The assumption behind these appeals is that involving members of study populations in the review process can help to identify and minimize collective risks (...) that otherwise could go unnoticed. In contrast to this position, critics have argued that supplemental community-based reviews are unnecessary, impractical, and morally problematic. This paper is our attempt to advance this debate by distinguishing the various goals of community review and the forms that it can take. (shrink)

Strategies for protecting historically disadvantaged groups have been extensively debated in the context of genetic variation research, making this a useful starting point in examining the protection of social groups from harm resulting from biomedical research. We analyze research practices developed in response to concerns about the involvement of indigenous communities in studies of genetic variation and consider their potential application in other contexts. We highlight several conceptual ambiguities and practical challenges associated with the protection of group interests and argue (...) that protectionist strategies developed in the context of genetic research will not be easily adapted to other types of research in which social groups are placed at risk. We suggest that it is this set of conceptual and practical issues that philosophers, ethicists, and others should focus on in their efforts to protect identifiable social groups from harm resulting from biomedical research.

The mechanism of stellar aberration was explained and formulated by Bradley in terms of the existence of a unique reference frame for light propagation. However, Einstein's denial of the existence of such a frame appears to undermine Bradley's interpretation of the phenomenon. It is suggested that the recent evidence for a cosmologically-based inertial reference frame provides a new physical basis for Bradley's explanation in a manner consistent with the requirements of special relativity. It is shown that a “delay” effect is (...) also involved in our observation of the direction of nearby sources, and that the aberration and delay effects exactly compensate for nearby sources comoving with a terrestrial observer.

This important book is the first serious philosophical examination of the modern state. It inquires into the justification of this particular form of political society. It asks whether all states are 'nation-states', what are the alternative ways of organizing society, and which conditions make a state legitimate. The author concludes that, while states can be legitimate, they typically fail to have the powers that they claim. Many books analyze government and its functions but none focuses on the state as a (...) distinctive form of political organization or examines critically the claims states make for themselves. In filling this lacuna Christopher Morris has written a book that will command the attention of political philosophers, political scientists, legal theorists, and specialists in international relations.

This is a new release of the original 1948 edition.

This book reflects on the variety of ways in which mourning affects political and social life. Through the narrative of the contributors, the book demonstrates how mourning is intertwined with politics and how politics involves a struggle over which losses and whose lives can, or should, be mourned.

For several decades, Dr. Morris has worked primarily with twoproblems: the development of a general theory of signs, and thedevelopment of a general theory of value. He approached both problemsin terms of George Mead's theory of action or behavior. This bookbrings together these two lines of development. For several decades, Dr. Morris has worked primarily with two problems: the development of a general theory of signs, and the development of a general theory of value. He approached both problems (...) in terms of George Mead's theory of action or behavior. This book brings together these two lines of development. In many languages there is a term like the English "meaning" which has two poles: that which something signifies and the value or significance of what is signified. The nature of signification and significance, as well as their relations within human behavior, is the subject matter of this book. This book is addressed to philosophers and to students of the behavioral sciences, but it will also appeal to anyone seriously interested in the study of human communication. (shrink)

On the Edge of Anarchy completes A. John Simmons's exploration and development of Lockean moral and political philosophy, a project begun in The Lockean Theory of Rights (Princeton, 1992). In this new book, Simmons discusses the Lockean view of the nature of, grounds for, and limits on political relations between persons. Locke's ideas on this topic are probably the most influential in the history of political thought, but their philosophical virtues and implications have remained largely unappreciated. Here Simmons remedies this (...) situation by treating Locke as a philosopher, rather than as a theologian or an activist writing rhetorical political tracts. Locke's works emerge not as episodes in the history of ideas but as bodies of arguments addressing the same questions as contemporary philosophy. This book pursues the issues Locke raises far beyond the boundaries of his own texts and theories. By criticizing, streamlining, and developing Locke's views, Simmons elaborates a powerful Lockean political philosophy with strongly anarchistic implications. On the Edge of Anarchy will interest not only Locke specialists and political philosophers, but also students and professionals in philosophy, government, and law - and all others who are interested in the foundational political principles embraced and celebrated by Anglo-American societies.

This chapter asks the reader to contrast justice with some of the other central virtues—for instance, prudence, courage, temperance, or wisdom. Justice is different. Unlike these others, it is principally a social virtue; its interpersonal element is central. Other virtues, such as generosity, as well as benevolence or charity, are also interpersonal. But unlike justice, acts of generosity or benevolence are not owed to specific people. One ought to help others, but the choice of when and where to act benevolently (...) is for the most part up to the individual. In modern terms their requirements are duties of imperfect obligation; those of justice are for the most part owed to specific individuals. The thesis that the norms of justice are not always preemptive reasons may appear much less plausible regarding certain central norms of justice, for instance, the principle prohibiting the intentional killing of nonthreatening innocent persons. The same may be true with the prohibition of cruelty. (shrink)

An obituary of Jean E. Hampton (1954-1996) by the editors of Economics and Philosophy. At the time of her premature death, Jean was serving as a member of the Editorial Board of the journal.

One of the most noteworthy features of David Gauthier's rational choice, contractarian theory of morality is its appeal to self-interested rationality. This appeal, however, will undoubtedly be the source of much controversy and criticism. For while self-interestedness is characteristic of much human behavior, it is not characteristic of all such behavior, much less of that which is most admirable. Yet contractarian ethics appears to assume that humans are entirely self-interested. It is not usually thought a virtue of a theory that (...) its assumptions are literally false. What may be said on behalf of the contractarian? (shrink)
