Frequent lateral genetic transfer undermines the existence of a unique “tree of life” that relates all organisms. Vertical inheritance is nonetheless of vital interest in the study of microbial evolution, and knowing the “tree of cells” can yield insights into ecological continuity, the rates of change of different cellular characters, and the evolutionary plasticity of genomes. Notwithstanding within-species recombination, the relationships most frequently recovered from genomic data at shallow to moderate taxonomic depths are likely to reflect cellular inheritance. At the (...) same time, it is clear that several types of ‘average signals’ from whole genomes can be highly misleading, and the existence of a central tendency must not be taken as prima facie evidence of vertical descent. Phylogenetic networks offer an attractive solution, since they can be formulated in ways that mitigate the misleading aspects of hybrid evolutionary signals in genomes. But the connections in a network typically show genetic relatedness without distinguishing between vertical and lateral inheritance of genetic material. The solution may lie in a compromise between strict tree-thinking and network paradigms: build a phylogenetic network, but identify the set of connections in the network that are potentially due to vertical descent. Even if a single tree cannot be unambiguously identified, choosing a subnetwork of putative vertical connections can still lead to drastic reductions in the set of candidate vertical hypotheses.

In her 1996 book, Error and the Growth of Experimental Knowledge, Deborah Mayo argues that use- (or heuristic) novelty is not a criterion we need to consider in assessing the evidential value of observations. Using the notion of a “severe” test, Mayo claims that such novelty is valuable only when it leads to severity, and never otherwise. To illustrate her view, she examines the historical case involving the famous 1919 British eclipse expeditions that generated observations supporting Einstein's theory of gravitation (...) over Newton's. My plan here is to defend use-novelty as a valuable methodological principle. I begin by exposing a weakness in Mayo's criticism of use-novelty. Remedying this weakness re-establishes the worth of use-novelty under specific conditions; in particular, heuristically novel data are to be preferred, as I will say, “prima facie”. Armed with this revised version of use-novelty, I re-examine the history of the eclipse experiments and offer an interpretation of this episode that to an extent—and contrary to Mayo—restores the mildly heretical, Earman/Glymour evaluation of this episode offered in their (1980). I conclude by responding to criticism of my assessment of Mayo's work. (shrink)

Natural selection is commonly interpreted as the fundamental mechanism of evolution. Questions about how selection theory can claim to be the all-sufficient explanation of evolution often go unanswered by today's neo-Darwinists, perhaps for fear that any criticism of the evolutionary paradigm will encourage creationists and proponents of intelligent design.In Biological Emergences, Robert Reid argues that natural selection is not the cause of evolution. He writes that the causes of variations, which he refers to as natural experiments, are independent of (...) natural selection; indeed, he suggests, natural selection may get in the way of evolution. Reid proposes an alternative theory to explain how emergent novelties are generated and under what conditions they can overcome the resistance of natural selection. He suggests that what causes innovative variation causes evolution, and that these phenomena are environmental as well as organismal.After an extended critique of selectionism, Reid constructs an emergence theory of evolution, first examining the evidence in three causal arenas of emergent evolution: symbiosis/association, evolutionary physiology/behavior, and developmental evolution. Based on this evidence of causation, he proposes some working hypotheses, examining mechanisms and processes common to all three arenas, and arrives at a theoretical framework that accounts for generative mechanisms and emergent qualities. Without selectionism, Reid argues, evolutionary innovation can more easily be integrated into a general thesis. Finally, Reid proposes a biological synthesis of rapid emergent evolutionary phases and the prolonged, dynamically stable, non-evolutionary phases imposed by natural selection. (shrink)

The revolution involving the foundations of the physical sciences heralded by relativity and quantum theories has been stimulating philosophers for many years. Both of these comprehensive sets of concepts have involved profound challenges to traditional theories of epistemology, ontology, and language. This volume gathers six experts in physics, logic and philosophy to discuss developments in space exploration and nuclear science and their impact on the philosophy of science.

Theoretical explication of a growing body of empirical data on consciousness-related anomalous phenomena is unlikely to be achieved in terms of known physical processes. Rather, it will first be necessary to formulate the basic role of consciousness in the definition of reality before such anomalous experience can adequately be represented. This paper takes the position that reality is constituted only in the interaction of consciousness with its environment, and therefore that any scheme of conceptual organization developed to represent that reality (...) must reflect the processes of consciousness as well as those of its environment. In this spirit, the concepts and formalisms of elementary quantum mechanics, as originally proposed to explain anomalous atomic-scale physical phenomena, are appropriated via metaphor to represent the general characteristics of consciousness interacting with any environment. More specifically, if consciousness is represented by a quantum mechanical wave function, and its environment by an appropriate potential profile, Schrödinger wave mechanics defines eigenfunctions and eigenvalues that can be associated with the cognitive and emotional experiences of that consciousness in that environment. To articulate this metaphor it is necessary to associate certain aspects of the formalism, such as the coordinate system, the quantum numbers, and even the metric itself, with various impressionistic descriptors of consciousness, such as its intensity, perspective, approach/avoidance attitude, balance between cognitive and emotional activity, and receptive/assertive disposition. With these established, a number of the generic features of quantum mechanics, such as the wave/particle duality, and the uncertainty, indistinguishability, and exclusion principles, display metaphoric relevance to familiar individual and collective experiences. Similarly, such traditional quantum theoretic exercises as the central force field and atomic structure, covalent molecular bonds, barrier penetration, and quantum statistical collective behavior become useful analogies for representation of a variety of consciousness experiences, both normal and anomalous, and for the design of experiments to study these systematically.

The scientific, personal, and social implications of this revolutionary work are staggering. MARGINS OF REALITY is nothing less than a fundamental reevaluation of how the world really works.

Culp (1994) provides a defense for a form of experimental reasoning entitled 'robustness'. Her strategy is to examine a recent episode in experimental microbiology--the case of the mistaken discovery of a bacterial organelle called a 'mesosome'--with an eye to showing how experimenters effectively used robust experimental reasoning (or could have used robust reasoning) to refute the existence of the mesosome. My plan is to criticize Culp's assessment of the mesosome episode and to cast doubt on the epistemic significance of robustness. (...) In turn, I present a different account of the experimental reasoning microbiologists used in arriving at the conclusion that mesosomes are artifacts. I call this form of reasoning 'reliable process reasoning', and close the paper with a brief discussion of how experimental microbiologists justify the claim that an experimental process is reliable.

This original new work takes a sharply focused look at Berkeley's ontology and provides a fuller understanding of the relationship between, on the one hand, Berkeley's nominalism and antiabstractionism and, on the other, his principal arguments for idealism and his attempts to square his idealism with common sense. Drawing heavily on detailed textual analysis, historical context, and careful examination of the work of other scholars, Muehlmann challenges, modifies, rejects, and exploits some well-established interpretations of Berkeley's philosophy.

Turnbull offers a close and detailed reading of the Parmenides, using his interpretation to illuminate Plato's major late dialogues. The picture presented of Plato's later philosophy is plausible, highly interesting, and original.

Based on the "Guide to the Human Fertilisation and Embryology Act 1990", this volume reviews the regulation of assisted conception including complex moral issues such as abortion, embryo research and cloning.

In 1993, an astonishing discovery was made at a tomb in Guodian in Hubei province (east central China). Written on strips of bamboo that have miraculously survived intact since 300 B.C., the "Guodian Laozi," is by far the earliest version of the _Tao Te Ching_ ever unearthed. Students of ancient Chinese civilization proclaimed the text a decisive breakthrough in the understanding of this famous text: it provides the most conclusive evidence to date that the text was the work of multiple (...) authors and editors over hundreds of years, rather than the achievement of a single individual writing during the time of Confucius. Robert Henricks now presents the first English translation of the "bamboo slip Laozi." Differing substantially from other versions we have of the text, the Guodian Laozi provides us with clues on how and when the text came into being. As Henricks's translation shows, many chapters are missing in this form of the text, and some chapters remain incomplete. All of this seems to suggest that the _Tao Te Ching_ was not yet "complete" when these slips were copied. In his translation, Henricks focuses attention on lines in each of the chapters that vary from readings in other editions. In addition, he shows how the sequence of chapters in this form of the text is totally unrelated to the sequence readers commonly see in the "standard" form of the text, i.e., in other translations. Here are just a few of the noteworthy features of this new _Tao Te Ching:_ • A lucid introduction to the Guodian Laozi, offering background on the archaeological interpretation of the discovery • Line-by-line comparisons of the Guodian Laozi against the Mawangdui and Wang Bi editions • Extensive notes on each chapter describing the unique elements of the Guodian Laozi in comparison with other versions • Transcriptions for each chapter, noting both the ancient and modern form of the characters in the chapter • An appendix featuring the official biography of Laozi written by Sima Qian, the Grand Historian of China, as well as Henricks's commentary and notes on this biography This groundbreaking work will lead to a reassessment of the history and significance of this well-known and critical work as well as a reevaluation of the role it played in the development of Taoism in early China.

The six essays in this volume discuss philosophical thought on scientific theory including: a call for a realist, rather than instrumentalist interpretation of science; a critique of one of the core ideas of positivism concerning the relation between observational and theoretical languages; using aerodynamics to discuss the representational aspect of scientific theories and their isomorphic qualities; the relationship between the reliability of common sense and the authenticity of the world view of science; removing long-held ambiguities on the theory of inductive (...) logic; and the relationship between the actuality of conceptual revolutions in the history of science and traditional philosophical pictures of scientific theory-building.

In the history of science, only three hundred years separate the discoveries of Galileo and Albert Einstein. Recent science has brought us relativity theory, quantum mechanics, and elementary particle physics-in a radical and mercurial departure from earlier developments. In this collection of essays, four philosophers and one physicist consider the interactions of mathematics and physics with logic and philosophy in the rapidly changing environment of modern science.

In 1942 a coalition of twenty scientific societies formed the Conference on the Supply of Experimental Animals in an attempt to pressure the Medical Research Council to accept responsibility for the provision of standardised experimental animals in Britain. The practice of animal experimentation was subject to State regulation under the Cruelty to Animals Act of 1876, but no provision existed for the provision of animals for experimental use. Consequently, day-to-day laboratory work was reliant on a commercial small animal market which (...) had emerged to sustain the hobby of animal fancying. This paper explores how difficulties encountered in experimental practice within the laboratory led to the problematisation of biomedical science’s reliance upon a commercial market for animals during the inter-war period. This is shown to have produced a crisis within animal reliant experimental science in the early 1940s which enabled the left-wing Association of Scientific Workers to cast science’s reliance on a free market as economically inefficient and a threat to the reliability of British research. It is argued that the development of standard experimental animals in Britain was, therefore, embedded within the wider cultural, societal, political and economic national context of the time.

Morrison offers an illuminating study of two linked traditions that have figured prominently in twentieth-century thought: Buddhism and the philosophy of Nietzsche. Nietzsche admired Buddhism, but saw it as a dangerously nihilistic religion; he forged his own affirmative philosophy in reaction against the nihilism that he feared would overwhelm Europe. Morrison shows that Nietzsche's influential view of Buddhism was mistaken, and that far from being nihilistic, it has notable and perhaps surprising affinities with Nietzsche's own project of the transvaluation of (...) all values.

The Structure of Scientific Revolutions) and Alan Musgrave argue that it is impossible to precisely date discovery events and precisely identify discoverers. They defend this claim mainly on the grounds that so-called discoverers have in many cases misconceived the objects of discovery. In this paper, I argue that Kuhn and Musgrave arrive at their view because they lack a substantive account of how well discoverers must be able to conceptualize discovered objects. I remedy this deficiency by providing just such an (...) account, and with this account I delineate how one can secure precision regarding the identity of discoverers and the times of discoveries. Near the end of my paper I bring my target of criticism up-to-date; it turns out that Steve Woolgar adopts an approach to discovery kindred to those of Kuhn and Musgrave and I close the paper by discussing what is at stake in rebutting him.

Significant to Dunn's critique of poststructuralist and postmodern theories is his application of George Herbert Mead as a means of theorizing identity and difference.

Nursing advocacy for patients is considered to be an essential component of nursing practice. This phenomenological qualitative pilot study explored registered nurses' lived experience of nursing advocacy with patients using a sample of three medical-surgical registered nurses. The guiding research questions were: (1) how do registered nurses practicing in the medical-surgical specialty area describe their experiences with nursing advocacy for their patients; and (2) what reflections on educational preparation for their professional roles do registered nurses identify as related to their (...) practices of nursing advocacy with their patients? Data analysis procedures were based on Moustakas' data analysis method, and Lincoln and Guba's criteria were applied for rigor. The emergent themes were: speaking out and speaking for patients; being compelled to act on unmet needs of patients; fulfillment and frustration; the patient is changed; primarily learned on the job; and confidence gained through practice. The findings increase the body of knowledge surrounding nursing advocacy as practiced by nurses. (shrink)

While naturalism is used in positive senses by the tradition of analytical philosophy, with Ludwig Wittgenstein its best example, and by the tradition of phenomenology, with Maurice Merleau-Ponty its best exemplar, it also has an extremely negative sense on both of these fronts. Hence, both Merleau-Ponty and Wittgenstein in their basic thrusts adamantly reject reductionistic naturalism. Although Merleau-Ponty’s phenomenology rejects the naturalism Husserl rejects, he early on found a place for the “truth of naturalism.” In a parallel way, Wittgenstein accepts (...) a certain positive sense of naturalism, while rejecting Quine’s kind of naturalism. It is the aim of this paper to investigate the common ground in the views of Wittgenstein and Merleau-Ponty regarding the naturalism that they each espouse and that which they each reject. (shrink)

In this paper I distinguish two kinds of predictivism, 'timeless' and 'historicized'. The former is the conventional understanding of predictivism. However, I argue that its defense in the works of John Worrall and Patrick Maher is wanting. Alternatively, I promote an historicized predictivism, and briefly defend such a predictivism at the end of the paper.

In lieu of an abstract, here is a brief excerpt of the content:Eidos/idea in IsocratesRobert G. SullivanFor modern readers, the career and literary output of the Attic rhetorician Isocrates is uncomfortably situated at the boundary between what we conceive as technical rhetoric and professional philosophy. Much of this confusion may be due to Isocrates' famous description of his program as being a philosophia (Panegyricus 10, 47; Evagoras 8, 81; Panathenaicus 9; Against the Sophists 1, 11-18, 21; Antidosis 30, 42-50, 162, (...) 176, 181-92).1 Over the years, the issue has exercised a large number of scholars who have tried to specify what Isocrates meant by the term and what matters he considered to be within his purview.2 Recently, the idea has been advanced that Isocrates and Plato consciously struggled over the use of the term (Nehamas 1990, 4; Timmerman 1998, 145). In Nehamas's very useful formulation, Isocrates thought philosophy to be "the ability to speak well, which in turn reflects and is the product of thinking well and shrewdly about practical affairs" (1990, 4). Timmerman's review of the relevant literature shows how Isocrates' conflation of philosophia and hê tôn logôn paideia has hurt his reputation among modern disciplinary philosophers: "This confusion and resultant devaluation of Isocrates' philosophy is predicated on a platonically colored view of what constitutes philosophy" (1998, 147). More recently, others have made efforts to recover Isocrates for philosophy by concentrating on those parts of his program that are of interest to philosophers of our era.3As a result, there has been a long-standing critical misapprehension regarding how best to interpret his works. Simply put, a question arises as to whether we should interpret them as bei. (shrink)

Patient advocacy is an important aspect of nursing care, yet there are few instruments to measure this essential function. This study was conducted to develop, determine the psychometric properties, and support validity of the Protective Nursing Advocacy Scale (PNAS), which measures nursing advocacy beliefs and actions from a protective perspective. The study used a descriptive correlational design with a systematically selected sample of 419 medical-surgical registered nurses. Analysis of the 43-item instrument was conducted using principal components analysis with promax rotation, (...) which resulted in the items loading onto four components. The four subscales have sufficient internal consistency, as did the overall PNAS. Satisfactory evidence of construct, content, and convergent validity were determined. Implications for nursing practice include using the PNAS in conjunction with an educational program to enhance advocacy skills, which may help to improve patient outcomes. (shrink)

The goal of this paper is to defend the claim that there is such a thing as direct perception, where by ‘direct perception’ I mean perception unmediated by theorizing or concepts. The basis for my defense is a general philosophic perspective which I call ‘empiricist philosophy’. In brief, empiricist philosophy (as I have defined it) is untenable without the occurrence of direct perception. It is untenable without direct perception because, otherwise, one can't escape the hermeneutic circle, as this phrase is (...) used in van Fraassen (1980). The bulk of the paper is devoted to defending my belief in direct perception against various objections that can be posed against it. I discuss various anticipations of my view found in the literature, eventually focusing on Ian Hacking's related conception of `entity realism' (Hacking 1983). Hacking has been criticized by a number of philosophers and my plan is to respond to these criticisms on behalf of entity realism (or more precisely on behalf of the claim that direct perception is a reality) and to then respond to other possible criticisms that can be launched against direct perception.
