Theories in the usual sense, as characterized by a language and a set of theorems in that language ("statement view"), are related to theories in the structuralist sense, in turn characterized by a set of potential models and a subset thereof as models ("non-statement view", J. Sneed, W. Stegmüller). It is shown that reductions of theories in the structuralist sense (that is, functions on structures) give rise to so-called "representations" of theories in the statement sense and vice versa, where representations (...) |

The historical development of the electronic configuration model is traced and the status of the model with respect to quantum mechanics is examined. The successes and problems raised by the model are explored, particularly in chemical ab initio calculations. The relevance of these issues to whether chemistry has been reduced to quantum mechanics is discussed, as are some general notions on reduction. |

Douglas W. Hands's “What Economics Is Not: An Economist's Response to Rosenberg“ is an unsympathetic criticism of the explanatory hypotheses of “If Economics Isn't Science, What Is It?”. Before replying to his objection, I summarize the claims of that paper. |

Criteria are given to characterize mature theories in contradistinction to developing theories. We lean heavily on the physical sciences. An established theory is defined as a mature one with known validity limits. The approximate truth of such theories is thereby given a quantitative character. Superseding theories do not falsify established theories because the latter are protected by their validity limits. This view of scientific realism leads to ontological levels and cumulativity of knowledge. It is applied to a defense of realism (...) |

According to the Incommensurability Thesis (IT) superseding scientific theories (paradigms) are incommensurable. Unlike many authors we do not discuss whether there is a relationship of this kind. We take for granted that this may be the case, and see the problem in the endeavour to establish the domain of validity of the IT. The notion incommensurability (Ic) is derivative from the concepts of scientific paradigm (P) and scientific revolution (R). There are several concepts of P, as well as various conceptions (...) |

This paper proposes that the philosophy of Bernard Lonergan can provide insight into the challenge of integrating nursing theory, research and practice. The author discusses Lonergan's work in regard to reflective understanding, authenticity and the human person as a subject of consciously developing unity. This is followed by a discussion of two key elements in Lonergan's work that relate to nursing: the subject–object challenge of nursing inquiry and common sense vs. scientific knowledge. The author suggests that integration of nursing theory, (...) |

We revive the idea that a deductive-nomological explanation of a scientific theory by its successor may be defensible, even in those common and troublesome cases where the theories concerned are mutually incompatible; and limiting, approximating and counterfactual assumptions may be required in order to define a logical relation between them. Our solution is based on a general characterization of limiting relations between physical theories using the method of nonstandard analysis. |

The main puzzle about theoretical definitions is that nothing seems to decide which assumptions contribute to such definitions and which do not. I argue that theoretical definitions are indeed imprecise, but that this does not normally matter, since the definitional imprecision does not normally produce indeterminacy of referential value. Sometimes, however, the definitional imprecision is less benign, and does generate referential indeterminacy. In these special cases, but not otherwise, it is necessary to refine the term's definition. |

Looking at Thomas Kuhn's work from a cognitive science perspective helps to articulate and to legitimize, to some degree, his rejection of traditional views of concepts, categorization, theory structure, and rule-based problem solving. Whereas my colleagues focus on the later Kuhn of the MIT years, I study the early Kuhn as an anticipation of case-based reasoning and schema theory. These recent developments in cognitive psychology and artificial intelligence may point toward a more computational version of Kuhn's ideas, but they also (...) |

An amended bootstrapping can avoid Christensen's counterexamples. Earman and Edidin argue that Christensen's examples to bootstrapping rely on his failure to analyze background knowledge. I add an additional condition to bootstrapping that is motivated by Glymour's remarks on variety of evidence. I argue that it avoids the problems that the examples raise. I defend the modification against the charge that it is holistic, and that it collapses into Bayesianism. |

The following article treats the 'applicational turn' of modern fluid dynamics as it set in at the beginning of the 20th century with Ludwig Prandtl's concept of the boundary layer. It seeks to show that there is much more to applying a theory in a highly mathematical field like fluid dynamics than deriving a special case from a general explanatory theory under particular antecedent conditions. In Prandtl's case, the decisive move was to introduce a model that provided a physical/causal conception (...) |

Relativism is one of the most tenacious theories about truth, with a pedigree as old as philosophy itself. Nearly as ancient is the chief criticism of relativism, namely the charge that the theory is self-refuting. This paper develops a logic of relativism that (1) illuminates the classic self-refutation charge and shows how to escape it; (2) makes rigorous the ideas of truth as relative and truth as absolute, and shows the relations between them; (3) develops an intensional logic for relativism; (...) |

In arguing a "role for history," Kuhn was proposing a naturalized philosophy of science. That, I argue, is the only viable approach to the philosophy of science. I begin by exhibiting the main general objections to a naturalistic approach. These objections, I suggest, are equally powerful against nonnaturalistic accounts. I review the failure of two nonnaturalistic approaches, methodological foundationism (Carnap, Reichenbach, and Popper) and metamethodology (Lakatos and Laudan). The correct response, I suggest, is to adopt an "evolutionary perspective." This perspective (...) |

Sometimes a theory is interpreted realistically--i.e., as literally true--whereas sometimes a theory is interpreted instrumentalistically--i.e., as merely a convenient device for summarizing, systematizing, deducing, etc., a given body of observable facts. This paper is part of a program aimed at determining the basis on which scientists decide on which of these interpretations to accept a theory. I proceed by examining one case: the nineteenth-century debates about the existence of atoms. I argue that there was a gradual transition from an instrumentalist (...) |

Mathematicians and physical scientists depend heavily on the formal symbolism of mathematics in order to express and develop their theories. For this and other reasons the last hundred years has seen a growing interest in the nature of formal language and the way it expresses meaning; particularly the objective, shared aspect of meaning as opposed to subjective, personal aspects. This dichotomy suggests the question: do the objective philosophical theories of meaning offer concepts which can be applied in psychological theories of (...) |

This paper argues, first, that recent studies of experimentation, most notably by Deborah Mayo, provide the conceptual resources to describe scientific discovery's early stages as error-probing processes. Second, it shows that this description yields greater understanding of those early stages, including the challenges that they pose, the research strategies associated with them, and their influence on the rest of the discovery process. Throughout, the paper examines the phenomenon of "chemical hormesis" (i.e., anomalous low-dose effects from toxic chemicals) as a case (...) |

The biological effects of low doses of toxic and carcinogenic chemicals are currently a matter of significant scientific controversy. This paper argues that philosophers of science can contribute to alleviating this controversy by examining it with the aid of a novel account of scientific anomaly. Specifically, analysis of contemporary research on chemical hormesis (i.e., alleged beneficial biological effects produced by low doses of substances that are harmful at higher doses) suggests that scientists may initially describe anomalous phenomena in terms of (...) |

Inflationary cosmology won a large following on the basis of the claim that it solves various problems that beset the standard big bang model. We argue that these problems concern not the empirical adequacy of the standard model but rather the nature of the explanations it offers. Furthermore, inflationary cosmology has not been able to deliver on its proposed solutions without offering models which are increasingly complicated and contrived, which depart more and more from the standard model it was supposed (...) |

This paper articulates a feminist poststructural philosophy of education by combining the work of Luce Irigaray and Michel Foucault. This acts as an underpinning for a philosophy of desire (McWilliam, 1999) in education, or as a minor philosophy of education where multiple movements of bodies are enacted through theoretical methodologies and research. These methods include qualitative analysis and critical discourse analysis; where the conjunction Irigaray-Foucault is a paradigm for dealing with educational phenomena. It is also a rigorous materialism (Braidotti, 2005) (...) |

How is scientific knowledge used, adapted, and extended in deriving phenomena and real-world systems? This paper aims at developing a general account of 'applying science' within the exemplar-based framework of Data-Oriented Processing (DOP), which is also known as Exemplar-Based Explanation (EBE). According to the exemplar-based paradigm, phenomena are explained not by deriving them all the way down from theoretical laws and boundary conditions but by modelling them on previously derived phenomena that function as exemplars. To accomplish this, DOP proposes to (...) |

I argue that the naturalism of Thomas Kuhn’s The Structure of Scientific Revolutions, which he himself later ignored, is worthy of rehabilitation. A naturalistic conception of paradigms is ripe for development with the tools of cognitive science. As a consequence a naturalistic understanding of world-change and incommensurability is also viable. |

In this paper I draw a connection between Kuhn and the empiricist legacy, specifically between his thesis of incommensurability, in particular in its later taxonomic form, and van Fraassen's constructive empiricism. I show that if it is the case the empirically equivalent but genuinely distinct theories do exist, then we can expect such theories to be taxonomically incommensurable. I link this to Hacking's claim that Kuhn was a nominalist. I also argue that Kuhn and van Fraassen do not differ as (...) |

Reasoners compare problems to prior cases to draw conclusions about a problem and guide decision making. All Case-Based Reasoning (CBR) employs some methods for generalizing from cases to support indexing and relevance assessment and evidences two basic inference methods: constraining search by tracing a solution from a past case or evaluating a case by comparing it to past cases. Across domains and tasks, however, humans reason with cases in subtly different ways evidencing different mixes of and mechanisms for these components.In (...) |

In this article, I discuss Gadamer's hermeneutic account of understanding as an alternative to Kuhn's incommensurability thesis. After a brief account of Kuhn's aesthetic account and arguments against it, I argue that the linguistic account faces a paradox that results from Kuhn's objectivist account of understanding, and his lack of historical reflexivity. The statement 'Languages are incommensurable' is not a unique view of language, and is thus subject to contest by incommensurable readings. Resolving the paradox requires an account of incommensurability (...) |

What do appeals to case studies accomplish? Consider the dilemma: On the one hand, if the case is selected because it exemplifies the philosophical point, then it is not clear that the historical data hasn't been manipulated to fit the point. On the other hand, if one starts with a case study, it is not clear where to go from there—for it is unreasonable to generalize from one case or even two or three. |

Karl Marx and Sigmund Freud provided powerful accounts of systematic interested ignorance. Fifty years ago, Anglo-American philosophies of science stigmatized Marx's and Freud's analyses as models of irrationality. They remain disvalued today, at a time when virtually all other humanities and social science disciplines have returned to extract valuable insights from them. Here the argument is that there are reasons distinctive to philosophy why such theories were especially disvalued then and why they remain so today. However, there are even better (...) |

It is no secret that scientists argue. They argue about theories. But even more, they argue about the evidence for theories. Is the evidence itself trustworthy? This is a bit surprising from the perspective of traditional empiricist accounts of scientific methodology according to which the evidence for scientific theories stems from observation, especially observation with the naked eye. These accounts portray the testing of scientific theories as a matter of comparing the predictions of the theory with the data generated by (...) |

In the course of defending both a unified model of intertheoretic relations in science and scientific realism, Paul Churchland has attempted to reinvigorate eliminative materialism. Churchland's eliminativism operates on three claims: (1) that some intertheoretic contexts involve incommensurable theories, (2) that such contexts invariably require the elimination of one theory or the other, and (3) that the relation of psychology and neuroscience is just such a context. I argue that a more detailed account of intertheoretic relations, which distinguishes between the (...) |

This article addresses the question how philosophy should be evaluated in a research-grant funding environment. It offers a new conception of philosophy that is inclusive and builds on familiar elements of professional, philosophical practice. Philosophy systematically questions the questions we ask, the concepts we use, and the values we hold. Its product is therefore rarely conclusive but can be embodied in everything we do. This is typical of explorative research and differentiates it from exploitative research, which constitutes the bulk of (...) |

In Kitzmiller v. Dover (2005), the only U.S. federal case on teaching Intelligent Design in public schools, the plaintiffs used the same argument as in the creation-science trials of the 1980s: Intelligent Design is religion, not science, because it invokes the supernatural; thus teaching it violates the Constitution. Although the plaintiffs won, this strategy is unwise because it is based on problematic definitions of religion and science, leads to multiple truths in society, and is unlikely to succeed before the present (...) |

The present paper is an inquiry into the role of the teacher in the context of the dominant Indian value system, an imposed curriculum and teacher-students interactions from the social psychological and critical interdisciplinary perspectives. The role of the school in the present modernist worldview is to frame and impart knowledge which may lead to economic growth. In this context, the role of the teacher is observed as being limited to a bearer of information rather than a leader who visualizes (...) |

Computer simulation of an epistemic landscape model, modified to include explicit representation of a centralized funding body, show the method of funding allocation has significant effects on communal trade-off between exploration and exploitation, with consequences for the community’s ability to generate significant truths. The results show this effect is contextual, and depends on the size of the landscape being explored, with funding that includes explicit random allocation performing significantly better than peer-review on large landscapes. The paper proposes a way of (...) |

Today, Larry Laudan is known predominantly for his work on the pessimistic metainduction and for his discussion of science and values. This essay examines a less familiar part of Laudan’s work, his typology of historical methodologies from the late 1970s. My aim is to elucidate Laudan’s typology and to examine one of the types in more depth, namely, the “pragmatic, symbiotic” model of historical methodology. Laudan expounded the model in the essays that eventually became his 1981 book Science and Hypothesis. (...) |
