Popper, Polanyi and Duncker represent the widely held position that theoretical and experimental scientific research are motivated by problems to which discoveries are solutions. According to the argument here, their views are unsupported and - in light of counter-instances, anomalous chance discoveries, and the force of curiosity - over-generalized.

There has been a significant interest in the recent literature in developing a solution to the problem of theory choice which is both normative and descriptive, but agent-based rather than rule-based, originating from Pierre Duhem’s notion of ‘good sense’. In this paper we present the properties Duhem attributes to good sense in different contexts, before examining its current reconstructions advanced in the literature and their limitations. We propose an alternative account of good sense, seen as promoting social consensus in science, (...) and show that it is superior to its rivals in two respects: it is more faithful to Duhemian good sense, and it cashes out the effect that virtues have on scientific progress. We then defend the social consensus account against objections that highlight the positive role of diversity and division of labour in science. (shrink)

In this article I discuss a recent argument due to Dan McArthur, who suggests that the charge that Michael Friedman’s relativised a priori leads to irrationality in theory change can be avoided by adopting structural realism. I provide several arguments to show that the conjunction of Friedman’s relativised a priori with structural realism cannot make the former avoid the charge of irrationality. I also explore the extent to which Friedman’s view and structural realism are compatible, a presupposition of McArthur’s argument. (...) This compatibility is usually questioned, due to the Kantian aspect of Friedman’s view, which clashes with the metaphysical premise of scientific realism. I argue that structural realism does not necessarily depend on this premise and as a consequence can be compatible with Friedman’s view, but more importantly I question whether Friedman’s view really implies mind dependence.

The way scientific discovery has been conceptualized has changed drastically in the last few decades: its relation to logic, inference, methods, and evolution has been deeply reloaded. The ‘philosophical matrix’ moulded by logical empiricism and analytical tradition has been challenged by the ‘friends of discovery’, who opened up the way to a rational investigation of discovery. This has produced not only new theories of discovery, but also new ways of practicing it in a rational and more systematic way. Ampliative rules, (...) methods, heuristic procedures and even a logic of discovery have been investigated, extracted, reconstructed and refined. The outcome is a ‘scientific discovery revolution’: not only a new way of looking at discovery, but also a construction of tools that can guide us to discover something new. This is a very important contribution of philosophy of science to science, as it puts the former in a position not only to interpret what scientists do, but also to provide and improve tools that they can employ in their activity.

It is argued that philosophical realism is well suited to serve as a perspective from which to understand nursing, and that it should be considered as an alternative to positivist, interpretivist, hermeneutical and phenomenological approaches. However, existing forms of realism, including theory and entity realism are shown to be faced with serious problems. In response, an alternative form ‘constraint realism’ is outlined, and shown to be apposite for illuminating the rule or convention governed behaviour characteristic of human beings. A brief (...) sketch is offered of its application to the social practice of nursing. (shrink)

The concept of approximate truth plays a prominent role in most versions of scientific realism. However, adequately conceptualizing ?approximate truth? has proved challenging. This article argues that the goal of articulating the concept of approximate truth can be advanced by first investigating the processes by which science accords theories the status of accepted or rejected. Accordingly, this article uses a path diagram model as a visual heuristic for the purpose of showing the processes in science that are involved in determining (...) a theory's status. This ?inductive realist? model of theory status then serves as a starting point for explicating an inductive realist view of approximate truth that, it is argued, can explain instances of the success of science, but does not (1) require science's theories to be strictly true in any world or (2) require a metric for measuring how close an approximately true theory is to some strictly true theory. To show the advantages of the inductive realist approach to approximate truth, an example of a major success story of science, the successful eradication of smallpox, is reviewed and then explained.

This paper starts with an intuitive notion of representational spaces, which is intended to provide an improved version of Kuhn's concept of paradigms. It then proceeds to study the following topics in terms of this new notion: incommensurability, paradigm change, explanation of anomalies, explanation of regularities, explanation of irregularities, and physical necessity. In the course of the investigation, "representational space" gets clarified and defined. It is envisaged that this new concept should throw light on many issues in the philosophy of (...) science.

The point of this paper is to provide a principled framework for a naturalistic, interactivist-constructivist model of rational capacity and a sketch of the model itself, indicating its merits. Being naturalistic, it takes its orientation from scientific understanding. In particular, it adopts the developing interactivist-constructivist understanding of the functional capacities of biological organisms as a useful naturalistic platform for constructing such higher order capacities as reason and cognition. Further, both the framework and model are marked by the finitude and fallibility (...) that science attributes to organisms, with their radical consequences, and also by the individual and collective capacities to improve their performances that learning organisms display. Part A prepares the ground for the exposition through a critique of the dominant Western analytic tradition in rationalising science, followed by a brief exposition of the naturalist framework that will be employed to frame the construction. This results in two sets of guidelines for constructing an alternative. Part B provides the new conception of reason as a rich complex of processes of improvement against epistemic values, and argues its merits. It closes with an account of normativity and our similarly developing rational knowledge of it, including (reflexively) of reason itself. (shrink)

For several decades, economists have been preoccupied with an attempt to place their entire subject on the ‘sound microfoundations’ of general equilibrium theory, with its individualistic premises. However, this project has run into seemingly intractable problems. This essay examines underlying questions such as the appropriate building block of analysis and the structure of explanation in economics. The examination of biology is found to be instructive, due to debates concerning the limitations of reductionism within that discipline. The final part of the (...) paper argues for the autonomy of a non‐reductionist macroeconomics, based on the institution as the unit of analysis. (shrink)

The inductive argument from the falsity of most past scientific theories (more than 100 years old) to the falsity of most present ones is defensible, I argue, if it is modified to account for the degrees of theoreticity or observationality in such theories, and the extent to which they are hedged. The case of descriptive astronomy is examined to show that most of the true theories of the 1890s were high in observationality and/or significantly hedged. The false theories of that (...) period, however, were not even approximately true. Apparently, scientists are more interested in supplanting theories with improved observations than in producing true theories. (shrink)

Cognitive and social sciences such as psychology and sociology are often described as immature sciences. But what is immaturity? According to the received view, immaturity is disunity, where disunity can usefully be cashed out in terms of having a plurality of disunified frameworks in play, where these frameworks consist of concepts, theories, goals, practices, methods, criteria for what counts as a good explanation, etc. However, there are some reasons to think that the cognitive and social sciences should be disunified in (...) this sense. If that is right, either these sciences should remain immature, or we need a new account of immaturity. The former option is unappealing. I therefore provide an alternative account of immaturity, based on Dudley Shapere’s work on the internal/external distinction. I then go on to use this account to argue against the imposition of unification on the cognitive and social sciences. Acceptance of disunity may be the route to maturity, rather than a sign of immaturity. (shrink)

This paper analyzes the main features of rational choice theory and evaluates it with respect to the conceptions of Lakatos' research program and Laudan's research tradition. The analysis reveals that the thin rationality assumption, the axiomatic method and the reduction to the micro level are the only features shared by all rational choice models. On these grounds, it is argued that rational choice theory cannot be characterized as a research program. This is due to the fact that the thin rationality (...) assumption cannot be understood as a hard core in Lakatos' terms. It is argued that Laudan's conception of a research tradition better characterizes rational choice theory. On the basis of this conclusion, certain important criticisms of rational choice theory are answered. First, the criticisms concerning the core assumptions of rational choice theory are countered. It is argued that this critique is based on a misunderstanding of rational choice theory as a unified set of models, such as Lakatos' research program. Second, Green and Shapiro's rational choice 'pathologies' - inconsistent predictions, post hoc theory development and arbitrary domain restrictions - are evaluated. Contrary to Green and Shapiro, it is argued that post hoc theory development is a more preferable strategy for developing RCT than domain restrictions based on ex ante rules. (shrink)

Alvin Weinberg’s classic and much debated two articles in Minerva, “Criteria for Scientific Choice” (1963) and “Criteria for Scientific Choice II – The Two Cultures” (1964), represent two of the first and most important attempts to create a meta-discourse about priority setting in science policy, and many of the points advanced remain relevant. The goal of this paper is to elaborate on the relevance of some of Weinberg’s original arguments to priority setting today. We have singled out four issues for (...) attention: The tension between scientific and institutional choice, the assumptions behind the triad of scientific, technological and social merit, the elusive ‘externality from size’ argument for funding promoted by Weinberg, and finally the problems involved in the idea of basic science as an ‘overhead cost’ for applied science, and applied science as an ‘overhead’ on a sectoral mission. These four issues will be elaborated from a policy perspective and connected to present day challenges for science and technology policy. (shrink)

The Macarthur-Wilson equilibrium theory of island biogeography has had a contradictory role in ecology. As a lasting contribution, the theory has created a new way of viewing insular environments as dynamical systems. On the other hand, many of the applications of the theory have reduced to mere unimaginative curve-fitting. I analyze this paradox in semiotic terms: the theory was mainly equated with the simple species-area relationship which became a signifier of interesting island ecology. The theory is, however, better viewed as (...) a theoretical framework that suggests specific hypotheses on the ecology of colonization of insular environments. This paradox is inherent in the use of simplifying analytic models. Analytic models are necessary and fruitful in the work of ecologists, but they ought to be supplemented with a broader, pluralistic appreciation of the role of theories in general. (shrink)

Ecology has often been characterized as an immature scientific discipline. This paper explores some of the sources of this alleged immaturity. I argue that the perception of immaturity results primarily from the fact that historically ecologists have based their work upon two very different approaches to research.

The critical focus of this paper is on a claim made explicitly by Gilbert Harman and accepted implicitly by numerous others, the claim that naturalism supports concurrent defense of scientific objectivism and moral relativism. I challenge the assumptions of Harman's ‘argument from naturalism' used to support this combination of positions, utilizing. Hilary Putnam’s ‘companions in guilt’ argument in order to counter it. The paper concludes that while domain-specific anti-realism is often warranted, Harman’s own views about the objectivity of facts and (...) the subjectivity of values are better seen as stemming from scientistic ideals of knowledge than from dictates of naturalism. Scientists qua scientists make value judgments, and setting aside scientistic assumptions and unrealizable conceptions of scientific objectivity should lead us to more symmetrical metaphilosophical conception of epistemic and ethical normativity than that which underlies Harman's account.

Selectionist evolutionary theory has often been faulted for not making novel predictions that are surprising, risky, and correct. I argue that it in fact exhibits the theoretical virtue of predictive capacity in addition to two other virtues: explanatory unification and model fitting. Two case studies show the predictive capacity of selectionist evolutionary theory: parallel evolutionary change in E. coli, and the origin of eukaryotic cells through endosymbiosis.

This book critically examines Freud's own detailed arguments for his major explanatory and therapeutic principles, the current neorevisionist versions of psychoanalysis, and the hermeneuticists' reconstruction of Freud's theory and therapy as an alternative to what they claim was a “scientistic” misconstrual of the psychoanalytic enterprise. The clinical case for Freud's cornerstone theory of repression – the claim that psychic conflict plays a causal role in producing neuroses, dreams, and bungled actions – turns out to be ill-founded for two main reasons: (...) Even if clinical data were valid, the method of free association has failed to support the psychoanalytic theory of unconscious motivation; Clinical data tend in any case to be artifacts of the analyst's self-fulfilling expectations, thus losing much of their evidential value. The hypothesis that psychoanalytic treatment is in reality a placebo poses a serious challenge to the assumption that insight is a key causal factor when therapy is successful. This challenge has yet to be met by psychoanalysts. Similar conclusions undermine the neorevisionist versions of psychoanalysis. The most influential hermeneuticists, on the other hand, are shown to have imposed an alien philosophy on psychoanalysis, partly through their reliance on gross misconceptions of the natural sciences. Karl Popper's criticism of the Freudian corpus as empirically untestable has misjudged its evidential weaknesses, which are more subtle. If there exists empirical evidence for the principal psychoanalytic doctrines, it cannot be obtained without well-designed extraclinical studies of a kind that have for the most part yet to be attempted.

Explanatory inquiry characteristically begins with a certain puzzlement about the world. But why do certain situations elicit our puzzlement while others leave us, in some epistemically relevant sense, cold? Moreover, what exactly is involved in the move from a state of puzzlement to a state where one's puzzlement is satisfied? In this paper I try to answer both of these questions. I also suggest ways in which our account of scientific rationality might benefit from having a better sense of the (...) kind of epistemic goal we are trying to realize, when we engage in our explanatory inquiries.

But the dangers to abnormal discourse do not come from science or naturalistic philosophy. They come from the scarcity of food and from the secret police. Given leisure and libraries, the conversation which Plato began will not end in self‐objedification ‐ not because aspects of the world, or of human beings, escape being objects of scientific inquiry, but simply because free and leisured conversation generates abnormal discourse as the sparks fly upward.

A conception of social epistemology is articulated with links to studies of science and opinion in such disciplines as history, sociology, and political science. The conception is evaluative, though, rather than purely descriptive. Three types of evaluative approaches are examined but rejected: relativism, consensualism, and expertism. A fourth, truth-linked, approach to intellectual evaluation is then advocated: social procedures should be appraised by their propensity to foster true belief. Standards of evaluation in social epistemics would be much the same as those (...) in individual epistemics, only the objects of evaluation would be interpersonal patterns of judgment and communication, and institutional practices that bear on opinion formation.

Problem solving has recently become a central topic both in the philosophy of science and in cognitive science. This paper integrates approaches to problem solving from these two disciplines and discusses the epistemological consequences of such an integration. The paper first analyzes problem solving as getting a true answer to a question. It then explores some stages of cognitive activity relevant to question answering that have been delineated by historians and philosophers of science and by cognitive psychologists and artificial intelligencers. (...) The traditional opposition between discovery and justification is challenged. It is suggested that epistemology may be conceptualized, in part, as the critical assessment of problem-solving strategies. (shrink)

Economic forms of analysis have penetrated to many disciplines in the last 30 years: political science, sociology, law, social and political philosophy, and so forth. We wish to extend the economic paradigm to certain problems in epistemology and the philosophy of science. Scientific agents, and scholarly inquirers generally, act in some ways like vendors, trying to "sell" their findings, theories, analyses, or arguments to an audience of prospective "buyers". The analogy with the marketplace is imperfect. The ideas or discoveries that (...) a scientist offers are not private goods in the economist's sense. Nonetheless, there are parallels with the marketplace that are worth exploring. (shrink)

The aim of this paper is to establish a substantial positive philosophical connection between Bas van Fraassen and Hegel, by focusing on their respective notions of ‘stance’ and ‘form of consciousness’. In Section I, I run through five ways of understanding van Fraassen’s idea of a stance. I argue that a ‘stance’ is best understood as an intellectual disposition. This, in turn, means that the criteria for assessing a stance are ones which ask whether or not a stance adequately makes (...) sense of things. In Section II, the discussion turns to Hegel’s notion of a ‘form of consciousness’. I argue that Hegel’s notion of a ‘form of consciousness’ is best understood as comprising a worldview. The principal advantage of articulating stances in a Hegelian way is that such an interpretation improves on the previous five ways of understanding stances. This is because a form of consciousness explicitly details both the theoretical and affective attitudes that van Fraassen is after. Therefore, why Hegel is potentially a better source of understanding stances than the other accounts is that forms of consciousness most clearly illustrate the pragmatist elements of a stance.

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 (...) is defended against one recent critic (Putnam). To argue the plausibility of a naturalistic approach, I next sketch a naturalistic account of theories and of theory choice. This account is then illustrated by the recent revolution in geology. In conclusion I return to Kuhn's question about the role of history in developing a naturalistic theory of science. (shrink)
