Kegley's primary intent is to show that neo-realism ignores factors that influence international actors, and that a theory is needed that expands the notion of self-interest to include the moral sphere.

In a recent article Merritt has claimed that current observational data provide “severe tests” falsifying the standard cosmological model. Based on Popper’s idea of conventionalism, he concludes that the introduction of some essential components of the standard cosmological model—including dark matter and dark energy—are a consequence of conventionalist stratagems. In this article, I provide more recent discoveries and discussions showing that the standard cosmological model is not built on any conventionalist stratagem.

Barry Barnes and David Bloor of the Strong Programme of the sociology of knowledge advance a naturalized epistemology that reduces all accounts of normativity to social causes. I endorse their program of naturalizing one kind of normativity, but I argue that there is another kind they cannot naturalize. Within the context of sociological explanations of rationality, there are norms of rationality instantiated by scientists that Barnes and Bloor study, and Barnes and Bloor's own normative ascriptions of scientists as rational beings. (...) I argue that Barnes and Bloor successfully justify their naturalization of the norms of rationality of the scientists they describe by a methodological caution and arguments from under-determination and finitism. But they inevitably fail to naturalize their own normative ascriptions of those scientists as rational. (shrink)

From its inception Darwinian evolutionary biology has been seen as having a problematic relationship of fact and theory. While the forging of the modern evolutionary synthesis resolved most of these issues for biologists, critics continue to argue that natural selection and common descent are “only theories.” Much of the confusion engendered by the “evolution wars” can be clarified by applying the concept of phenomena, inferred from fact, and explained by theories, thus locating where legitimate dissent may still exist. By setting (...) such analysis in the context of research traditions, it is possible to gain further insight into the complex interplay of facts, phenomena, and theories. Two case studies are explored to assess the value of such approaches, one from within evolutionary biology, the Baldwin effect, and one from outside, intelligent design. (shrink)

Social constructivist approaches to science have often been dismissed as inaccurate accounts of scientific knowledge. In this article, we take the claims of robust social constructivism (SC) seriously and attempt to find a theory which does instantiate the epistemic predicament as described by SC. We argue that Freudian psychoanalysis, in virtue of some of its well-known epistemic complications and conceptual confusions, provides a perfect illustration of what SC claims is actually going on in science. In other words, the features SC (...) mistakenly ascribes to science in general correctly characterize the epistemic status of Freudian psychoanalysis. This sheds some light on the internal disputes in the field of psychoanalysis, on the sociology of psychoanalytic movement, and on the “war” that has been waged over Freud's legacy with his critics. In addition, our analysis offers an indirect and independent argument against SC as an account of bona fide science, by illustrating what science would look like if it were to function as SC claims it does.

An immunizing strategy is an argument brought forward in support of a belief system, though independent from that belief system, which makes it more or less invulnerable to rational argumentation and/or empirical evidence. By contrast, an epistemic defense mechanism is defined as a structural feature of a belief system which has the same effect of deflecting arguments and evidence. We discuss the remarkable recurrence of certain patterns of immunizing strategies and defense mechanisms in pseudoscience and other belief systems. Five different (...) types will be distinguished and analyzed, with examples drawn from widely different domains. The difference between immunizing strategies and defense mechanisms is analyzed, and their epistemological status is discussed. Our classification sheds new light on the various ways in which belief systems may achieve invulnerability against empirical evidence and rational criticism, and we propose our analysis as part of an explanation of these belief systems’ enduring appeal and tenacity.

Remarks on Interpretation, Confirmation and Progressiveness of Early Matrix Mechanics. Our note discusses a case study in view of questions of theory-choice. We examine the extent to which the first 'complete, consistent exposition' of matrix mechanics in 1925 can be claimed to be reasonably confirmed, well interpreted and fruitful. Various strategies, by means of deductions and otherwise, by Born, Jordan and Heisenberg to establish these claims are critically assessed. It is shown that the outcome of the Bothe-Geiger experiment does not (...) represent a 'direct' confirmation of the theory. Finally we pose the question of progressiveness and argue for a low over-all 'problem-solving effectiveness'. (shrink)

In recent years, there have been some attempts to defend the legitimacy of a non-inductive generative logic of discovery whose strategy is to analyze a variety of constraints on the actual generation of explanatory hypotheses. These proposed new theories, however, are only weakly generative (relying on sophisticated processes of elimination) rather than strongly generative (embodying processes of correction).This paper develops a strongly generative theory which holds that we can come to know something new only as a variant of what we (...) already know — and that the novelty of this variant is not thereby eliminated nor beyond our powers of characterization, a double requirement that is vital for resolving the Meno paradox. In this light, the discovery of a new hypothesis is taken as the correction of an antecedent hypothesis in response to the discrepancies between the predictions generated by that antecedent hypothesis and the desired result (e.g. the actual data to be explained). This process comprises two parallel operations: the first, which demonstrates the positive role of the facts in generating new explanations, involves a mapping between multiple hypotheses and sets of predictions generated from those hypotheses, for the purpose of taking the actual data as a determinable variant of neighboring sets of predictions. This mapping permits the facts to indicate how corrective adjustments in the working hypothesis should be made; the second operation, which demonstrates the positive role of explanations in generating new facts, involves a mapping between differently construed versions of the actual data and the conceptualizations derived from those perceptual versions, for the purpose of taking the working hypothesis as a determinable variant of these neighboring conceptualizations. This mapping permits a given hypothesis to generate predictions increasingly closer to the actual facts. (shrink)

The aim of this paper is to address the neglected but important problem of differentiating between epistemically beneficial and epistemically detrimental dissent. By “dissent,” we refer to the act of objecting to a particular conclusion, especially one that is widely held. While dissent in science can clearly be beneficial, there might be some instances of dissent that not only fail to contribute to scientific progress, but actually impede it. Potential examples of this include the tobacco industry’s funding of studies that (...) questioned the link between smoking and lung cancer, and the attempt by the petroleum industry and other groups to cast doubt upon the conclusion that human consumption of fossil fuels contributes to global climate change. The problem of distinguishing between good and bad dissent is important because of the growing tendency of some stakeholders to attempt to delay political action by ’manufacturing doubt’. Our discussion in this paper focuses on climate science. This field, in our view, is rife with instances of bad dissent. On the basis of our discussion of climate science, we articulate a set of sufficient conditions for epistemically problematic dissent in general, which we call “the inductive risk account of epistemically detrimental dissent.”.

In a thought experiment we want to test how the emergence of adult neural stem cells could constitute an example for a scientific revolution in the sense of Thomas Kuhn. In his major work, The structure of scientific revolutions, 3rd edn, University of Chicago Press, Chicago (Kuhn 1996), the philosopher of science, Thomas Kuhn, states that scientific progress is not a cumulative process, but new theories appear by a rather revolutionary sequence of events. Kuhn built his theory on landmark events (...) taken from chemistry and physics, lacking examples from biology. Beginning with Ramon y Cajal’s famous quote, no new neurons after birth , from the early years of the twentieth century, and Reynolds and Weiss’s conflicting finding in 1992 of adult neural stem cells giving rise to new neurons, we will test how the finding of neural stem cells in the adult brain matches with Kuhn’s theory. The pivotal problem of defining a paradigm will be our main focus, since the emergence of adult neural stem cells has been acclaimed by the scientific community as the rebuttal of Ramon y Cajal’s paradigm.

In education there is a concern that science teachers misrepresent the nature of science to students. An assumption that is implicit in this concern is that science teachers should be teaching the philosophy of science as it is understood by philosophers. This paper argues that both philosophers and science teachers misrepresent science when they engage in their respective disciplines, and it is evident the two misrepresentations are of different types. In philosophy, the misrepresentation is of a philosophical-epistemological nature where advocates (...) of particular views maintain that advocates of other views misinterpret the nature of science. In education, the misrepresentation is of a cognitive, teaching nature where teachers'' practical interpretations are not congruent with philosophers'' interpretations of science. The discrepancy that exists between the two misrepresentations is due to the intentions of the two disciplines, and assuming that science teachers should teach a philosophically coherent interpretation of the nature of science is an over-simplification of the problem. The concepts of espoused theories and theories-in-use are used to link the two interpretations of science and provide suggestions for future research that may help clarify misrepresentations of science in science education.

This article differentiates between three different axes of conflict in world risk society. The first axis is that of ecological conflicts, which are by their very essence global. The second is global financial crises, which, in a first stage, can be individualized and nationalized. And the third, which suddenly broke upon us on September 11th, is the threat of transnational terror networks, which empowers governments and states. Two sets of implications are drawn: first, there are the political dynamics of world (...) risk society. In an age where trust and faith in God, class and progress have largely disappeared, humanity's common fear has proved the last - ambivalent - resource for making new bonds. Second, the methodological nationalism that preoccupies the sociological imagination has to be overcome and a `methodological cosmopolitism' has to be created. (shrink)

The study “Psychoanalysis—its image and its public” intimates that common sense is increasingly informed by science. But common sense asserts its autonomy and, in turn, may affect the trajectory of science. This is a process that leads to many differentiations—in common sense, in scientific innovation and in political and regulatory structures. Bauer and Gaskell's toblerone model of triangles of mediation provided a distillation of their reading of “La Psychanalyse.” Here it was argued that representations are multi-modal phenomena necessitating the use (...) of multiple methodologies .In this paper we briefly summarise these arguments and elaborate ways in which social representation theory can be considered a progressive research programme. “Progressive” because as the theory has developed it has extended the range and depth of its conceptual basis; it provides a new synthesis for the social scientific understanding of the phenomena of common sense and of representation; it acts as an antidote to the reductionism of public opinion and, finally, it is a stimulus to depart from disciplinary silos. However, there remain unresolved issues: how to segment the relevant social milieus and how to close the feedback loop from common sense to science? (shrink)

According to the instrumentalism of Friedman and Machlup it is irrelevant whether the explanatory principles or “assumptions” of a theory satisfy any criterion of “plausibility,” “realism,” “credibility,” or “soundness.” In this view the main or only criterion for selecting theories is whether a theory yields empirically testable implications that turn out to be consistent with observations. All we should require or expect from a theory is that it is a useful instrument for the purpose of prediction. Considerations of the “efficiency” (...) of a theory for the purpose of ordering our experiences are permitted, but considerations of “plausibility” are not. “Explanatory assumptions” are not really explanatory in the sense that they claim to represent underlying causal processes in reality; they only serve to generate, by deduction, implications that are in accordance with as many observations as possible.

Abstract.Evolutionary psychology and behavioural genomics are both approaches to explain human behaviour from a genetic point of view. Nonetheless, thus far the development of these disciplines is anything but interdependent. This paper examines the question whether evolutionary psychology can contribute to behavioural genomics. Firstly, a possible inconsistency between the two approaches is reviewed, viz. that evolutionary psychology focuses on the universal human nature and disregards the genetic variation studied by behavioural genomics. Secondly, we will discuss the structure of biological explanations. (...) Some philosophers rightly acknowledge that explanations do not involve laws which are exceptionless and universal. Instead, generalisations that are invariant suffice for successful explanation as long as two other stipulations are recognised: the domain within which the generalisation has no exceptions as well as the distribution of the mechanism described by the generalisation should both be specified. It is argued that evolutionary psychology can contribute to behavioural genomic explanations by accounting for these two specifications. (shrink)

Recently improved understanding of evolutionary processes suggests that tree-based phylogenetic analyses of evolutionary change cannot adequately explain the divergent evolutionary histories of a great many genes and gene complexes. In particular, genetic diversity in the genomes of prokaryotes, phages, and plasmids cannot be fit into classic tree-like models of evolution. These findings entail the need for fundamental reform of our understanding of molecular evolution and the need to devise alternative apparatus for integrated analysis of these genomes. We advocate the development (...) of integrative phylogenomics for analyzing these genomes and their histories, with tools suited to analyzing the importance of lateral gene transfer (LGT) and of DNA evolution in extra-cellular mobile genetic elements (e.g., viruses, plasmids). These phenomena greatly increase the complexity of relationships among interacting genetic partners, as they exchange functional genetic units. We examine the ontology of functional genetic units, interacting genetic partners, and emergent genetic associations, argue that these three categories of entities are required for a successful integrated phylogenomics. We conclude with arguments to suggest that the proposed new perspective and associated tools are suitable, and perhaps required, as a replacement for the bifurcating trees that have dominated evolutionary thinking for the last 150 years.

The article analyses in detail the Meselson–Stahl experiment, identifying two novel difficulties for the crucial experiment account, namely, the fragility of the experimental results and the fact that the hypotheses under scrutiny were not mutually exclusive. The crucial experiment account is rejected in favour of an experimental-mechanistic account of the historical significance of the experiment, emphasizing that the experiment generated data about the biochemistry of DNA replication that is independent of the testing of the semi-conservative, conservative, and dispersive hypotheses. _1_ (...)

Dans ce travail, je vais m'efforcer de critiquer la thèse poppérienne de la dissymétrie entre les procédures de vérification et de réfutation des théories empiriques. Pour caractériser les théories empiriques, j'utiliserai le critère suivant: l'analyse des procédures discursives employées ne suffit pas comme base de discussion de leur valeur de vérité. On doit faire appel à quelque chose dont on considère que la donnée est en quelque façon, et du point de vue de la connaissance, extérieure à la théorie. Dans (...) le titre, j'ai employé «falsification» parce que c'était le terme habituel des traducteurs français de Popper jusqu'à une date récente. Je trouve cette terminologie peu claire et j'utiliserai les couples vérifier/réfuter, confirmer/infirmer. (shrink)
