Despite its importance, the linkage between genetic and cultural evolution has until now been little explored. An understanding of this linkage is needed to extend evolutionary theory so that it can deal for the first time with the phenomena of mind and human social history. We characterize the process of gene-culture coevolution, in which culture is shaped by biological imperatives while biological traits are simultaneously altered by genetic evolution in response to cultural history. A case is made from both theory (...) and evidence that genetic and cultural evolution are inseverable, and that the human mind has tended to evolve so as to bias individuals toward certain patterns of cognition and choice rather than others. With the aid of mathematical models we trace the coevolutionary circuit: The genes prescribe structure in developmental pathways that lay down endocrine and neural systems, imposing regularities in the development of cognition and behavior; these regularities translate upward into holistic patterns of culture, which can be predicted in the form of probability density distributions ; natural selection acts within human history to favor certain epigenetic rules over others; and the selection alters the frequencies of the underlying genes. The effects of genetic and cultural changes reverberate throughout the circuit and are consequently tested with the passage of each life cycle. In addition to modeling gene-culture coevolution, we apply methods from island biogeography and information theory to examine the cultural capacity of the genes, the factors determining the magnitude of cultural diversity, and the possible reasons for the uniqueness of the human achievement.

Should engineering ethics be taught? Despite the obvious truism that we all want our students to be moral engineers who practice virtuous professional behavior, I argue, in this article that the question itself obscures several ambiguities that prompt preliminary resolution. Upon clarification of these ambiguities, and an attempt to delineate key issues that make the question a philosophically interesting one, I conclude that engineering ethics not only should not, but cannot, be taught if we understand “teaching engineering ethics” to mean (...) training engineers to be moral individuals (as some advocates seem to have proposed). However, I also conclude that there is a justification to teaching engineering ethics, insofar as we are able to clearly identify the most desirable and efficacious pedagogical approach to the subject area, which I propose to be a case study-based format that utilizes the principle of human cognitive pattern recognition.

When in 2006 the Centers for Disease Control and Prevention issued revised recommendations for HIV testing in health care settings, vocal opponents charged that use of an ?opt-out? approach to presenting HIV testing to patients; the implementation of nontargeted, widespread HIV screening; the elimination of a separate signed consent; and the decoupling of required HIV prevention counseling from HIV testing are unethical. Here we undertake the first systematic ethical examination of the arguments both for and against the recommendations. Our examination (...) reveals that the ethical concerns raised by the critics predominately pertain not to ethically suspect elements of the recommendations themselves, but to suspicions that they will be implemented improperly. It has not been shown that the recommendations cannot be implemented properly. Here we show that in the United States the recommendations are morally justifiable and that safeguards or regulatory oversight may serve to ensure that the recommendations are properly implemented.

Memory exhibits episodic superposition, an analog of the quantum superposition of physical states: Before a cue for a presented or unpresented item is administered on a memory test, the item has the simultaneous potential to occupy all members of a mutually exclusive set of episodic states, though it occupies only one of those states after the cue is administered. This phenomenon can be modeled with a nonadditive probability model called overdistribution (OD), which implements fuzzy-trace theory's distinction between verbatim and gist (...) representations. We show that it can also be modeled based on quantum probability theory. A quantum episodic memory (QEM) model is developed, which is derived from quantum probability theory but also implements the process conceptions of global matching memory models. OD and QEM have different strengths, and the current challenge is to identify contrasting empirical predictions that can be used to pit them against each other. (shrink)

Friendship, in its nature, purpose, and effects, has been an important concern of philosophy since antiquity. It was of particular significance in the life of Gilles Deleuze, one of the most original and influential philosophers of the late twentieth century. Taking L'Abécédaire de Gilles Deleuze -- an eight-hour video interview that was intended to be aired only after Deleuze's death -- as a key source, Charles J. Stivale examines the role of friendship as it appears in Deleuze's work and (...) life. Stivale develops a zigzag methodology practiced by Deleuze himself to explore several concepts as they relate to friendship and to discern how friendship shifts, slips, and creates movement between Deleuze and specific friends. The first section of this study discusses the elements of creativity, pedagogy, and literature that appear implicitly and explicitly in his work. The second section focuses on Deleuze's friendships with Foucault, Derrida, Claire Parnet, and Félix Guattari and reveals his conception of friendship as an ultimately impersonal form of intensity that goes beyond personal relationships. Stivale's analysis offers an intimate view into the thought of one of the greatest thinkers of our time. (shrink)

The Belmont Report’s distinction between research and the practice of accepted therapy has led various authors to suggest that these purportedly distinct activities should be governed by different ethical principles. We consider some of the ethical consequences of attempts to separate the two and conclude that separation fails along ontological, ethical, and epistemological dimensions. Clinical practice and clinical research, as with yin and yang, can be thought of as complementary forces interacting to form a dynamic system in which the whole (...) exceeds the sum of its parts. Just as effective clinical practice cannot exist without clinical research, meaningful clinical research requires the context of clinical practice. We defend this thesis by triangulation, that is, by outlining how multiple investigators have reached this conclusion on the basis of varied theoretical and applied approaches. More confidence can be placed in a result if different methods/viewpoints have led to that result. (shrink)

Background: In 2006, the Centers for Disease Control and Prevention (CDC) recommended three changes to HIV testing methods in US healthcare settings: (1) an opt-out approach, (2) removal of separate signed consent, and (3) optional HIV prevention counseling. These recommendations led to a public debate about their moral acceptability. Methods: We interviewed 25 members from the fields of US HIV advocacy, care, policy, and research about the ethical merits and demerits of the three changes to HIV testing methods. We performed (...) a qualitative analysis of the participant responses in the interviews and summarized the major themes. Results: In general, arguments in favor of the methods were based upon their ultimate contribution to increasing HIV testing and permitting the consequent benefits of identifying those who are HIV infected and linking them to further care. Conclusions: The prevailing theme of ethical concern focused on suspicions that the methods might not be properly implemented, and that further safeguards might be needed. (shrink)

The purpose of this paper is to review the rising influence of commercialism in American medicine and to examine some of the consequences of this trend. Increased competition subverts physician collegiality, draws hospitals into for-profit ownership and behavior, and leads clinical investigators into secrecy and possibly into bias and abuse. Medicine faces a deprofessionalization evidenced in loss of control over the clinical setting and over self-regulation. Health care becomes a commodity relying on cultivation of desires instead of satisfaction of needs, (...) even as many basic needs go unmet. Patients become consumers empowered with lawsuits and the connection of medicine to the relief of suffering is attenuated. Medical encounters are increasingly impersonal, dominated by specialization, technology, and bureaucracy. Patients are losing their physician-advocates to new conflicts of interests, physicians are losing their impulse to charity, and trust in the doctor-patient relationship and in medicine generally is eroding.

In this essay, we defend the design of the Salk polio vaccine trial and try to put some limits on the role schemata should play in designing clinical research studies. Our presentation is structured as a response to de Freitas and Pietrobon who identified the CONSORT statement as a schema that would have, had it existed at the time, ruled out the design of the Salk polio vaccine trial of 1954 in favor of a completely randomized controlled clinical trial. We (...) argue that large-scale public health interventions often require evidence beyond simple efficacy, the limit of what an RCT can provide, and that the design actually adopted for the Salk trial represented a reasonable—albeit imperfect—compromise. This is of more than historical interest in that many contemporary studies are of the scale and scope to require a more pragmatic, rather than explanatory, approach to study design. (shrink)

This article presents the rationale of a new approach to the debate between sociobiology and religion. In it, I outline a sociobiology that may generate alternative and competing hypotheses about the existence of gods as beings (theisms) and the nature of their participation in the universe. I examine the central theoretical issues of this sociobiology and discuss the strengths and weaknesses of a sociobiological approach to theological issues, including problems pertinent to nontheistic theologies. A concluding case is made for an (...) enriched and revitalized agenda in the dialogue between sociobiology and religion. While consistent with current research on gene‐culture coevolution, the article's treatment expands on earlier work to begin incorporating theoretical terms that carry a more direct theological impact.

It is well known that Augustine, Boethius, Anselm and Aquinas participated in a tradition of philosophical theology which determined God to be simple, perfect, immutable and timelessly eternal. Within the parameters of such an Hellenic understanding of the divine nature, they sought a clarification of one of the fundamental teachings of their Christian faith, the doctrine of the Trinity. These classical theists were not dogmatists, naively unreflective about the very possibility of their project. Aquinas, for instance, explicitly worried about and (...) fought to dispel the seeming contradiction between the philosophical requirement of divine simplicity and the creedal insistence on a threefold personhood in God. 1 Nevertheless, doubts abound. Philosophers otherwise friendly to Classical Theism still remain unsure about the coherence of affirming a God that is at once absolutely simple and triune. 2 A less friendly critic has even suggested that the theory of divine simplicity pressured Augustine and his medieval followers away from recognizing that real complexity within the life of God which Trinitarianism expresses. 3.

Man has the urge to thrust against the limits of language. Think for instance about one's astonishment that anything exists. This astonishment cannot be expressed in the form of a question and there is no answer to it. Anything we can say must, a priori, be nonsense.

Gilles Deleuze is now regarded as one of the most radical philosophers of the twentieth century. His work is hugely influential across a range of subjects, from philosophy to literature, to art, architecture and cultural studies. _Gilles Deleuze: Key Concepts_ provides a guide to Deleuzian thought for any reader coming to his writings for the first time. This new edition is fully revised and updated and includes three new chapters on the event, psychoanalysis and philosophy.

The 2006 Centers for Disease Control and Prevention (CDC) revised recommendations for HIV testing in clinical settings contained seven specific changes to how health care facilities should provide HIV testing. These seven elements have been both supported and challenged in the lay and medical literature. Our first paper in BMC Medical Ethics presented an analysis of the three HIV testing procedural changes included in the recommendations. In this paper, we address the four remaining elements that concern HIV screening policy changes: (...) (1) nontargeted HIV screening, (2) making HIV screening similar to screening for other treatable conditions, (3) increasing HIV screening without assured additional funding for linkage to care, and (4) making patients bear the costs of increased HIV screening in health care settings.

This volume sets Berkeley's philosophy in its historical context by providing selections from: firstly, works that deeply influenced Berkeley as he formed his main doctrines; secondly, works that illuminate the philosophical climate in which those doctrines were formed; and thirdly, works that display Berkeley's subsequent philosophical influence. The first category is represented by selections from Descartes, Malebranche, Bayle, and Locke; the second category includes extracts from such thinkers as Regius, Lanion, Arnauld, Lee, and Norris; while reactions to Berkeley, both positive (...) and negative, are drawn from a wide range of thinkers - Leibniz, Baxter, Hume, Diderot, Voltaire, Reid, Kant, Herder, and Mill.

I argue that sport hunting is a right thing according to Leopold’s land ethic. First, I argue that what Leopold means by a “thing” (“A thing is right...”) is not a human action, as is generally assumed, but rather a practice of conservation that is an activity connecting humans to the land. Such an “outdoor” activity emphasizes internal rewards and the achievement of excellence according to standards which at least partially define the activity. To say that hunting is a right (...) thing is to say that the practice of sport hunting tends in the direction of the land ethic. The actions of individual hunters are judged to be ethical or not by the standards of the practice; these standards are in turn evaluated by the precepts of the land ethic. Second, I discuss how the practical standards are evaluated. I argue that the concepts of integrity, stability, and beauty, contrary to some interpretations, are not inherent values of the biotic community, but rather labels carefully chosen by Leopold as three conduits for the ecological conscience necessary for the land ethic: the ethical, the ecological, and the aesthetic. I show that Leopold uses this model for his own evaluation of the practice of hunting as well as his evaluation of other practices of conservation. Thus, to ask about whether sport hunting is a right thing is to ask about the historical evolution of the standards of this practice and, of equal importance, about the future direction of these standards with regard to the land ethic.

The Standards of Ethical Conduct for Management Accountants (Statement 1C) promulgated by the National Association of Accountants on June 1, 1983, are described and critiqued in this article. Four major issues related to the issuance of the standards are discussed: (1) What are the basic requirements of any ethical system? Does Statement IC meet these requirements? (2) Should a professional be ethical? (3) If ethical behavior is desirable for management accountants, should such standards be formally expressed in writing? (4) If (...) the standards are expressed in writing, what format should be adopted for the content and how should the standards be expressed? (shrink)
