Concerns about energy security have dramatically increased since the terrorist attacks on September 11, 2001. If U.S. energy use follows business-as-usual projections, the energy system will become increasingly vulnerable. No quick fixes are available to make the United States energy independent. However, there are energy policies that promote efficiency and the use of renewable energy sources such as wind, biomass, geothermal, and solar can gradually reduce dependence on imported oil and natural gas and reduce the vulnerability of the U.S. energy (...) infrastructure to disruption of supplies or to attack. This article reviews recent analyses by the U.S. Energy Information Administration’s and by the Union of Concerned Scientists. These studies showthat efficiency and renewable energy investments can increase energy security while lowering consumer energy bills and reducing local and global environmental hazards. (shrink)

The guiding idea behind formalism is that mathematics is not a body of propositions representing an abstract sector of reality but is much more akin to a game, bringing with it no more commitment to an ontology of objects or properties than ludo or chess. This idea has some intuitive plausibility: consider the tyro toiling at multiplication tables or the student using a standard algorithm for differentiating or integrating a function. It also corresponds to some aspects of the practice of (...) advanced mathematicians in some periods—for example, the treatment of imaginary numbers for some time after Bombelli's introduction of them, and perhaps the attitude of some contemporary mathematicians towards the higher flights of set theory. Finally, it is often the position to which philosophically naïve respondents will gesture towards, when pestered by questions as to the nature of mathematics. (shrink)

Drawing upon ancient Hindu philosophy, the author explores the human psyche and the importance of personal identity.

The ubiquity of top-down causal explanations within and across the sciences is prima facie evidence for the existence of top-down causation. Much debate has been focused on whether top-down causation is coherent or in conflict with reductionism. Less attention has been given to the question of whether these representations of hierarchical relations pick out a single, common hierarchy. A negative answer to this question undermines a commonplace view that the world is divided into stratified ‘levels’ of organization and suggests that (...) attributions of causal responsibility in different hierarchical representations may not have a meaningful basis for comparison. Representations used in top-down and bottom-up explanations are primarily ‘local’ and tied to distinct domains of science, illustrated here by protein structure and folding. This locality suggests that no single metaphysical account of hierarchy for causal relations to obtain within emerges from the epistemology of scientific explanation. Instead, a pluralist perspective is recommended—many different kinds of top-down causation (explanation) can exist alongside many different kinds of bottom-up causation (explanation). Pluralism makes plausible why different senses of top-down causation can be coherent and not in conflict with reductionism, thereby illustrating a productive interface between philosophical analysis and scientific inquiry.

Idealization is a reasoning strategy that biologists use to describe, model and explain that purposefully departs from features known to be present in nature. Similar to other strategies of scientific reasoning, idealization combines distinctive strengths alongside of latent weaknesses. The study of ontogeny in model organisms is usually executed by establishing a set of normal stages for embryonic development, which enables researchers in different laboratory contexts to have standardized comparisons of experimental results. Normal stages are a form of idealization because (...) they intentionally ignore known variation in development, including variation associated with phenotypic plasticity (e.g. via strict control of environmental variables). This is a tension between the phenomenon of plasticity and the practice of staging that has consequences for evolutionary developmental investigation because variation is conceptually removed as a part of rendering model organisms experimentally tractable. Two compensatory tactics for mitigating these consequences are discussed: employing a diversity of model organisms and adopting alternative periodizations. (shrink)

A central reason that undergirds the significance of evo-devo is the claim that development was left out of the Modern synthesis. This claim turns out to be quite complicated, both in terms of whether development was genuinely excluded and how to understand the different kinds of embryological research that might have contributed. The present paper reevaluates this central claim by focusing on the practice of model organism choice. Through a survey of examples utilized in the literature of the Modern synthesis, (...) I identify a previously overlooked feature: exclusion of research on marine invertebrates. Understanding the import of this pattern requires interpreting it in terms of two epistemic values operating in biological research: theoretical generality and explanatory completeness. In tandem, these values clarify and enhance the significance of this exclusion. The absence of marine invertebrates implied both a lack of generality in the resulting theory and a lack of completeness with respect to particular evolutionary problems, such as evolvability and the origin of novelty. These problems were salient to embryological researchers aware of the variation and diversity of larval forms in marine invertebrates. In closing, I apply this analysis to model organism choice in evo-devo and discuss its relevance for an extended evolutionary synthesis. (shrink)

Reacting against the dominance of obligation-based moral theories in both general and nursing ethics, the author proposes a 'strong' (action-guiding) account of a virtue-based approach to moral decision-making within contemporary nursing practice. Merits and criticisms of obligation and virtue-based approaches to morality are identified and examined. One of the author's central premises is that the notions of moral goodness and badness carry more moral weight than the traditionally important notions of moral rightness and wrongness. Therefore, the author argues that in (...) order to deliver morally good care, it is vital to consider the kind of nurse one is and this means examining one's moral character. This book will be rewarding reading for a wide range of readers including clinical nurses, nurse educators and nurse ethicists; indeed, anyone interested in morality and ethics and the work of nurses will find this book stimulating reading.

Psychological and philosophical perspectives are employed in an exploration of the reasons particular individuals experience an activity as personally expressive while others may find the same activity neutral or even aversive. The relationships between personal expressiveness and intrinsic motivation, flow, and self-actualization are considered. The construct of personal expressiveness is shown to have its roots in eudaimonistic philosophy. Living in a manner consistent with one's daimon or "true self" gives rise to a cognitive-affective state labeled "eudaimonia" that is distinguishable from (...) hedonic enjoyment. A personally expressive personality pattern is described integrating concepts from diverse theories including a sense of personal identity, self-actualization, an internal locus of control, and principled moral reasoning. A series of empirical investigations is proposed to test the theoretical concepts of personal expressiveness advanced. (shrink)

Friends since childhood, Anais Darnby and Lindsay Markham have long harbored a secret passion for one another. When they finally confess their love, their future together seems assured, sealed with their searing embrace. But when a debauched Lindsay is seduced by a scheming socialite, a devastated Anais seeks refuge in another man's bed while Lindsay retreats to the exotic East. There, he is seduced again--this time by the alluring red smoke and sinister beauty of opium. Back home, Lindsay's addiction is (...) fed by the vogue for all things Oriental--especially its sensual pleasures--in fashionable London society. In his lucid moments, Lindsay still lusts after Anais, who can neither allow him near nor forget his smoldering touch. Tortured by two obsessions--opium and Anais--Lindsay must ultimately decide which is the one he truly cannot live without. (shrink)

Philosophers and psychologists have recently been focusing on the important question of how positive character traits are developed. Within philosophy, these positive character traits are referred to as virtues. In this chapter, I examine one intuitively appealing proposal concerning virtue development - the idea that the path to moral virtue can begin with the experience of admiration for a moral exemplar. My aim is to provide a model of how this process might work by identifying the different stages it would (...) involve. I then highlight three ways in which admiration might nevertheless fail to result in the development of moral virtue. It is hoped that providing this model, and identifying the potential problems, will be helpful for those interested in virtue education. (shrink)

White searches for the subtler side of Nietzsche beyond his ambiguous support for violence and oppression. He looks at the `yes saying teachings' articulated with the `voice of beauty'.

Since the 1950s, the cognitive revolution has been transforming work in psychology, linguistics, and anthropology. Literary scholars, however, have only recently begun to grapple with the significance of cognitive understandings of language, mind, and behavior for literary and cultural studies. This unique issue of Poetics Today brings the concerns of literary history and cultural studies for the first time into a sustained and productive dialogue with cognitive methods, findings, and paradigms.The introduction situates the collection in relation to previous work, defines (...) the issues, highlights the stakes. Articles by Mark Turner and Paul Hernadi propose a bold extension of notions of literary history to include not only preliterature oral forms but the entire history of the species, viewing literary activity as a crucial human adaptation. Ellen Spolsky's essay provides an unprecedented statement of common ground shared by cognitive-evolutionary approaches and poststructuralist theory. The final three essays examine works by Aphra Behn, A. L. Barbauld, and Jane Austen in terms of their contemporary cultural and political contexts as well as in light of paradigms drawn from cognitive neuroscience and evolutionary theory. A commentary by Tony Jackson surveys the entire issue from the viewpoint of an informed outsider. (shrink)
