Scientific breakthroughs rarely yield the potential to engage a foundational ethical question. Recent studies on direct reprogramming of human skin cells reported by the Yamanaka lab in Japan and the Thomson lab in Wisconsin suggest that scientists may have crossed both a scientific and an ethical threshold. The fascinating science of direct nuclear reprogramming highlights empirical data that may clarify the ontological status of cellular activity in the early stages of what could become a human fetus and justify ethical options (...) for research in this controversial field. The ontological and ethical implications that accrue here are connected with the biological or natural potentiality of these cells. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Direct Nuclear Reprogramming: Response to Condic, Lee, and GeorgeGerard Magill, Ph.D. and William B. NeavesWe read with great interest the response of Maureen Condic, Patrick Lee, and Robert George (2009) to our essay, “Ontological and Ethical Implications of Direct Nuclear Reprogramming” in the March 2009 issue of the Kennedy Institute of Ethics Journal (Magill and Neaves 2009). Much of their response addressed issues that are not in (...) dispute: somatic cells are not zygotes, neurons and hepatocytes are different, growth-factor signals from the trophoblast influence development of the inner cell mass, membranes derived from the trophectoderm are critically required for embryonic survival, and stem cells cannot produce a fetus “on their own.”The crucial point of disagreement deals with the fact that iPS cells are not totipotent but zygotes are. Zygotes can generate their own placental structures while iPS cells must be given them through tetraploid complementation. Condic, Lee, and George consider totipotency to be crucial to natural potentiality. We present an alternative view in our essay (Magill and Neaves 2009, pp. 28–29). Placental structures make no lasting contribution to the postnatal organism, and the equivalency of iPS cells with the inner cell mass of the blastocyst is apparent from tetraploid complementation experiments.The respondents acknowledge the following:... somatic cells can be “converted” into zygotes by the process of somatic cell nuclear transfer (SCNT) or direct reprogramming in combination with tetraploid complementation—just as sperm and egg cells can be “converted” into a zygote by the process of natural fertilization—....(Condic, Lee, and George 2009, p. 35)As the respondents recognize, different ways of manipulating cells can lead to embryogenesis: sperm and egg cells in the process of natural fertilization, the enucleated egg and an ordinary body cell in the process of somatic cell nuclear transfer, and reprogrammed skin cells and a tetraploid blastocyst in the case of induced pluripotent stem (iPS) cells. In each case, different cells are manipulated—or “converted” in the respondents’ terminology—in a process that alters their biological fate within a supportive environment facilitating embryogenesis.The developmental potential that resides in the human genome does not unfold in isolation, not even in a zygote. In all cases, whether involving a zygote or an iPS cell, interaction with a supportive environment is required to express the developmental program residing in the genome. [End Page 201]This biological reality supports what we have described as “early cellular development along the continuum of natural potentiality that can result in the formation of a fetus” (Magill and Neaves 2009, p. 30), and it presents a significant challenge to the natural potentiality argument.Gerard MagillVernon F.

This book provides a unique, cogent, engaging account of environmental determinism that has long been much needed in the classroom and beyond." -- Andrew Sluyter, Associate Professor, Louisiana State University, USA This book pulls together major critiques of contemporary attempts to explain nature-society relations in an environmentally deterministic way. After defining key terms, it reviews the history of environmental determinism's rise and fall within geography in the early twentieth century. It discusses the key reasons for the doctrine's rejection and presents (...) alternative, non-deterministic frameworks developed within geography for analyzing the roles played by the environment in human affairs. The authors examine the rise in recent decades of neo-deterministic approaches to such issues as the demarcation of regions, the causes of civilizational collapse in prehistory, today's globally uneven patterns of human well-being, and the consequences of human-induced climate change. In each case, the authors draw on the insights and approaches of geography, the academic discipline most conversant with the interactions of society and environment, to challenge the widespread acceptance that such approaches have won. The book will appeal to those working on human-environmental research, international development and global policy initiatives. William B. Meyer is Associate Professor of Geography at Colgate University, USA. He is the author of several previous books, including Human Impact on the Earth, Americans and Their Weather: A History, and The Progressive Environmental Prometheans. His research interests include urban geography, environmental history, and the history of environmental thought. Dylan M.T. Guss works in the technology investment sector. (shrink)

Imperative sentences like Dance! do not seem to represent the world. Recent modal analyses challenge this idea, but its intuitive and historical appeal remain strong. This paper presents three new challenges for a non-representational analysis, showing that the obstacles facing it are even steeper than previously appreciated. I will argue that the only way for the non-representationalist to meet these three challenges is to adopt a dynamic semantics. Such a dynamic semantics is proposed here: imperatives introduce preferences between alternatives. This (...) characterization of meaning focuses on what function a sentence serves in discourse, rather than what that sentence refers to (e.g., a state of the world). By representing the meaning of imperatives, connectives and declaratives in a common dynamic format, the challenges posed for non-representationalism are met. (shrink)

Modern Moral Problems addresses moral quandaries that can beguile and confuse faithful Catholics. Written in a question-and-answer format, the book covers questions regarding sexuality, medical ethics, business practices, civic responsibilities, and the sacramental life of the Church. The extraordinary assortment of issuesforming a single, organized collectionis a valuable reference for anyone seeking clear and concise answers to tough moral questions. Written in a conversational tone often spliced with humor, this work by a highly respected moral theologian will be read with (...) fascination for its clarity of argument and fundamental good sense. Originally published as a monthly question-and-answer column in a magazine for priests, these selections by Msgr. William B. Smith retain a striking current topicality. Msgr. Smith often tackled matters of controversy in the Catholic Church, ones which continue to draw conflicting opinions. Interesting, informative, and eminently practical, this book conveys an overall impression that sound thinking about morality is rooted in a tradition within the Catholic Church, even when the answers to particular moral questions cannot be found in catechisms or Vatican documents. Msgr. Smith offers a clear-headed approach to the quandaries of our time precisely because of his training in traditional moral principles and his fidelity to the Catholic magisterium. This book should be in the possession of all seminarians and priests, who are bound to confront moral matters that are not so easily decided at first glance. But lay people, too, will find here rich responses to the challenging and sometimes unresolved moral questions they encounter in their own lives. (shrink)

A uniform theory of conditionals is one which compositionally captures the behavior of both indicative and subjunctive conditionals without positing ambiguities. This paper raises new problems for the closest thing to a uniform analysis in the literature (Stalnaker, Philosophia, 5, 269–286 (1975)) and develops a new theory which solves them. I also show that this new analysis provides an improved treatment of three phenomena (the import-export equivalence, reverse Sobel-sequences and disjunctive antecedents). While these results concern central issues in the study (...) of conditionals, broader themes in the philosophy of language and formal semantics are also engaged here. This new analysis exploits a dynamic conception of meaning where the meaning of a symbol is its potential to change an agent’s mental state (or the state of a conversation) rather than being the symbol’s content (e.g. the proposition it expresses). The analysis of conditionals is also built on the idea that the contrast between subjunctive and indicative conditionals parallels a contrast between revising and consistently extending some body of information.

The ArgumentMany of the epistemological issues that occupied natural philosophers of the seventeenth century were expressed visually in title-page engravings. One of those issues concerned the relative status to be accorded to evidence of the senses, as compared to knowledge gained by faith or reason. In title-page illustrations, the various arguments were often waged by a series of light metaphors: the Light of Reason, the Light of Nature, and the Lights of Sense, Scripture, and Grace. When such illustrations are examined (...) with the authors' theological views in mind, it becomes apparent that in the first half of the seventeenth century, Catholic authors favored the Light of Reason as a source of truth, while Protestant authors favored the Light of Nature. Since by the end of the century it was widely accepted by scientists of all religious persuasions that certain knowledge must be grounded in sense evidence and the direct study of nature, one might argue that in this instance Protestantism was responsible for nurturing an important development of the Scientific Revolution. However, the skewed nature of the sample and the large number of counterexamples available mitigate against taking this offshoot of the Merton thesis too seriously. (shrink)

This paper proposes a semantics for free choice permission that explains both the non-classical behavior of modals and disjunction in sentences used to grant permission, and their classical behavior under negation. It also explains why permissions can expire when new information comes in and why free choice arises even when modals scope under disjunction. On the proposed approach, deontic modals update preference orderings, and connectives operate on these updates rather than propositions. The success of this approach stems from its capacity (...) to capture the difference between expressing the preferences that give rise to permissions and conveying propositions about those preferences.

No existing conditional semantics captures the dual role of 'if' in embedded interrogatives — 'X wonders if p' — and conditionals. This paper presses the importance and extent of this challenge, linking it to cross-linguistic patterns and other phenomena involving conditionals. Among these other phenomena are conditionals with multiple 'if'-clauses in the antecedent — 'if p and if q, then r' — and relevance conditionals — 'if you are hungry, there is food in the cupboard'. Both phenomena are shown to (...) be problematic for existing analyses. Surprisingly, the decomposition of conditionals needed to capture the link with interrogatives provides a new analysis that captures all three phenomena. The model-theoretic semantics offered here relies on a dynamic conception of meaning and compositionality, a feature discussed throughout. (shrink)

The rapid pace of technological development often outstrips the ability of legislators and regulators to establish proper guardrails on emerging technologies. A solution is for those who develop, deploy, and use these technologies to develop themselves as moral agents—i.e., as agents capable of steering the course of emerging technologies in a direction that will benefit humanity. However, there is a dearth of literature discussing how to foster moral agency in computer science courses, and little if any research on the effectiveness (...) of such courses in computer science. This paper addresses this gap by providing an overview of an undergraduate course on technology ethics. It then shares and discusses a subset of data collected from a mixed-methods study using a pre-post design that sought to examine the course’s effectiveness in developing students’ moral, intellectual, and civic virtues, as well as related dispositions.

In this paper, I examine various popular notions concerning the ethics of investing. I first consider and reject the absolutist view that it is always wrong to invest in evil companies and the view that what makes investments in evil companies morally objectionable is the fact that by making such investments, investors are taking steps to benefit from the wrongdoing of others. I then defend the view that what makes certain investments morally objectionable is the fact that by making such (...) investments, investors enable others to do wrong. According to this view, when weighing the purchase of a certain company's stock, investors should ask themselves the following question: Would this sort of investment, if made by many people, enable others to do wrong? If the answer to this question is yes, and if an investor nevertheless makes the investment in question, he can justifiably be accused of moral wrongdoing. (shrink)

This article examines the ethics of resource allocation by newspaper management. The notion of quality is used to link ethics and economics in publishing, and a quantitative standard of moral behavior in budgetary policy is offered.

Mr P. F. Strawson's book Individuals is subtitled An Essay in Descriptive Metaphysics. ‘Descriptive metaphysics’, he writes, ‘is content to describe the actual structure of our thought about the world’, whereas ‘revisionary metaphysics is concerned to produce a better structure’; it is distinguished from logical or conceptual analysis in scope and generality, rather than in fundamental intention. The book is divided into two parts; in Strawson's words, ‘the first part aims at establishing the central position which material bodies and persons (...) occupy among particulars in general. … In the second part of the book the aim is to establish and explain the connexion between the idea of a particular in general and that of an object of reference or logical subject.’.

Biodiversity and genetic resources have become the focal point of major national and international biological and political debates regarding control, ownership, access, and erosion of critical resources. While these issues are key to environmental sustainability and food security, biodiversity and genetic resources must be seen in the broader context of their inextricable relationship to cultural diversity and to humans' view of nature. Nature is assumed to be constituted socially through a wide variety of human processes described collectively as culture. Three (...) significant cultural factors, technology, science, and capitalism, are largely responsible for the secularization and homogenization of food and agriculture and the remaking of nature. These processes and forces may simultaneously and unwittingly create the problems of declines in biodiversity, cultural diversity, and food equity. Indeed, it may well be that the only way to conserve cultural biodiversity in the field is to conserve cultural diversity among peoples. This reunification of biodiversity and cultural diversity and food and agriculture will require new paradigms and institutional mechanisms that allow us to show our care for each other through our reverence for nature.
