Recent studies of the evolution of religion have revealed the cognitive underpinnings of belief in supernatural agents, the role of ritual in promoting cooperation, and the contribution of morally punishing high gods to the growth and stabilization of human society. The universality of religion across human society points to a deep evolutionary past. However, specific traits of nascent religiosity, and the sequence in which they emerged, have remained unknown. Here we reconstruct the evolution of religious beliefs and behaviors in early (...) modern humans using a global sample of hunter-gatherers and seven traits describing hunter-gatherer religiosity: animism, belief in an afterlife, shamanism, ancestor worship, high gods, and worship of ancestors or high gods who are active in human affairs. We reconstruct ancestral character states using a time-calibrated supertree based on published phylogenetic trees and linguistic classification and then test for correlated evolution between the characters and for the direction of cultural change. Results indicate that the oldest trait of religion, present in the most recent common ancestor of present-day hunter-gatherers, was animism, in agreement with long-standing beliefs about the fundamental role of this trait. Belief in an afterlife emerged, followed by shamanism and ancestor worship. Ancestor spirits or high gods who are active in human affairs were absent in early humans, suggesting a deep history for the egalitarian nature of hunter-gatherer societies. There is a significant positive relationship between most characters investigated, but the trait “high gods” stands apart, suggesting that belief in a single creator deity can emerge in a society regardless of other aspects of its religion.

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.

This article discusses two complementary themes that play an important role in contemporary South African political philosophy: (1) the racist tradition in Western philosophy; and (2) the role of ubuntu in regaining an authentic African identity, which was systematically suppressed during the colonial past and apartheid. These are also leading themes in Mogobe Ramose’s African Philosophy Through Ubuntu. The first part concentrates on John Locke. It discusses the thesis that the reprehensible racism of many founders of liberal political philosophy has (...) lethally infected liberal theory. This view neglects the distinction between genesis and justification. Political liberalism has since cleansed itself of the prejudices of its spiritual ancestors. Liberal human rights exclude racism as a matter of principle. The second part discusses the claim that the ubuntu philosophy provides a better basis for a constitution in a modern society than political liberalism. A major problem is that ubuntu is an essentially contested concept. Some philosophers consider ubuntu to be a moribund notion (Matolino); others see it as a vital concept par excellence. In the latter case, it is elaborated from sundry incompatible political views, ranging from African nationalism (Ramose) via humanist communitarianism (Metz) to liberalism (Mboti). Conclusion: as an essentially contested ideological concept, ubuntu should not be a decisive constitutional standard for the application of state force. In contrast, the constitutional model of political liberalism provides a reasonable alternative, as it is designed precisely to solve the problem of social plurality and ideological contest.

A square tabular array was introduced by R. C. Punnett in (1907) to visualize systematically and economically the combination of gametes to make genotypes according to Mendel’s theory. This mode of representation evolved and rapidly became standardized as the canonical way of representing like problems in genetics. Its advantages over other contemporary methods are discussed, as are ways in which it evolved to increase its power and efficiency, and responded to changing theoretical perspectives. It provided a natural visual decomposition of (...) a complex problem into a number of inter-related stages. This explains its computational and conceptual power, for one could simply “read off” answers to a wide variety of questions simply from the “right” visual representation of the problem, and represent multiple problems, and multiple layers of problems in the same diagram. I relate it to prior work on the evolution of Weismann diagrams by Griesemer and Wimsatt (What Philosophy of Biology Is, Martinus-Nijhoff, the Hague, 1989), and discuss a crucial change in how it was interpreted that midwifed its success.

© 2014 Taylor Francis. The Centers for Disease Control and Prevention recommends routine human immunodeficiency virus testing of every client presenting for services in venues where HIV prevalence is high. Because older adults have particularly poor prognosis if they receive their diagnosis late in the course of HIV disease, any screening provided to younger adults in these venues should also be provided to older adults. We examined aging-related disparities in recent and ever HIV testing in a probability sample of at-risk (...) adults seeking services in needle exchange sites, sexually transmitted disease clinics, and Latino community clinics that provide HIV testing. Using multiple logistic regression with generalized estimating equations, we estimated associations between age category and each HIV testing outcome. Even after controlling for covariates such as recent injection drug use, older adults had 40% lower odds than younger adults did of having tested in the past 12 months or ever. Aging-related disparities in HIV testing exist among clients of these high HIV prevalence venues and may contribute to known aging-related disparities in late diagnosis of HIV infection and poor long-term prognosis.

I take this opportunity of correcting a particularly reprehensible error of my own on p. 140 of my edition of these poems. At A.A. 1. 730 read ‘…hoc multri †non ualuisse† putant’; and at 11. 3-4 of the critical apparatus read ‘equidem multi utique’ eqs. In other words, the manuscripts are unanimous in offering multi. I hope that Dr. Lenz will be glad to have this evidence of our common humanity.

In this paper, it is argued that the prima facie conflict between special relativity and the quantum-mechanical collapse postulate is only apparent, and that the seemingly incompatible accounts of entangled systems undergoing collapse yielded by different reference frames can be regarded as no more than differing accounts of the same processes and events. Attention to the transformation properties of quantum-mechanical states undergoing unitary, non-collapse evolution points the way to a treatment of collapse evolution consistent with the demands of relativity.

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)
