In this paper it is argued that qualitative theories (Q-theories) can be used to describe the statistical structure of cross classified populations and that the notion of verisimilitude provides an appropriate tool for measuring the statistical adequacy of Q-theories. First of all, a short outline of the post-Popperian approaches to verisimilitude and of the related verisimilitudinarian non-falsificationist methodologies (VNF-methodologies) is given. Secondly, the notion of Q-theory is explicated, and the qualitative verisimilitude of Q-theories is defined. Afterwards, appropriate (...) measures for the statistical verisimilitude of Q-theories are introduced, so to obtain a clear formulation of the intuitive idea that the statistical truth about cross classified populations can be approached by falsified Q-theories. Finally, it is argued that some basic intuitions underlying VNF-methodologies are shared by the so-called prediction logic, developed by the statisticians and social scientists David K. Hildebrand, James D. Laing and Howard Rosenthal. (shrink)

The Nicomachean Ethics is generally thought to be a “dialectical” work, aimed at resolving aporia in a set of endoxa, which it takes as its starting-point. I argue that Aristotle’s aim in the treatise is, rather, to produce definitions of key ethical terms, and that his starting-points are limited to evaluative and discriminative judgments of a certain sort, which are demanded by the nature of the discipline and are not endoxa. I discuss also how the definitions are reached (focusing on (...) the cases of the virtues of character) and the roles that aporiai do play in the process. (shrink)

Karl Popper (1902-1994) was one of the most influential philosophers of science of the 20th century. He made significant contributions to debates concerning general scientific methodology and theory choice, the demarcation of science from non-science, the nature of probability and quantum mechanics, and the methodology of the social sciences. His work is notable for its wide influence both within the philosophy of science, within science itself, and within a broader social context. Popper’s early work attempts to solve the problem of (...) demarcation and offer a clear criterion that distinguishes scientific theories from metaphysical or mythological claims. Popper’s falsificationist methodology holds that scientific theories are characterized by entailing predictions that future observations might reveal to be false. When theories are falsified by such observations, scientists can respond by revising the theory, or by rejecting the theory in favor of a rival or by maintaining the theory as is and changing an auxiliary hypothesis. In either case, however, this process must aim at the production of new, falsifiable predictions. While Popper recognizes that scientists can and do hold onto theories in the face of failed predictions when there are no predictively superior rivals to turn to. He holds that scientific practice is characterized by its continual effort to test theories against experience and make revisions based on the outcomes of these tests. By contrast, theories that are permanently immunized from falsification by the introduction of untestable ad hoc hypotheses can no longer be classified as scientific. Among other things, Popper argues that his falsificationist proposal allows for a solution of the problem of induction, since inductive reasoning plays no role in his account of theory choice. Along with his general proposals regarding falsification and scientific methodology, Popper is notable for his work on probability and quantum mechanics and on the methodology of the social sciences. Popper defends a propensity theory of probability, according to which probabilities are interpreted as objective, mind-independent properties of experimental setups. Popper then uses this theory to provide a realist interpretation of quantum mechanics, though its applicability goes beyond this specific case. With respect to the social sciences, Popper argued against the historicist attempt to formulate universal laws covering the whole of human history and instead argued in favor of methodological individualism and situational logic.

K. R. Popper distinguished between two main uses of logic, the demonstrational one, in mathematical proofs, and the derivational one, in the empirical sciences. These two uses are governed by the following methodological constraints: in mathematical proofs one ought to use minimal logical means (logical minimalism), while in the empirical sciences one ought to use the strongest available logic (logical maximalism). In this paper I discuss whether Popper’s critical rationalism is compatible with a revision of logic in the empirical sciences, (...) given the condition of logical maximalism. Apparently, if one ought to use the strongest logic in the empirical sciences, logic would remain immune to criticism and, thus, non-revisable. I will show that critical rationalism is theoretically compatible with a revision of logic in the empirical sciences. However, a question that remains to be clarified by the critical rationalists is what kind of evidence would lead them to revise the system of logic that underlies a physical theory, such as quantum mechanics? Popper’s falsificationist methodology will be compared with the recently advocated extension of the abductive methodology from the empirical sciences to logic by T. Williamson, since both of them arrive at the same conclusion concerning the status of classical logic. (shrink)

I discuss methodology in epistemology. I argue that settling the facts, even the epistemic facts, fails to settle the questions of intellectual policy at the center of our epistemic lives. An upshot is that the standard methodology of analyzing concepts like knowledge, justification, rationality, and so on is misconceived. More generally, any epistemic method that seeks to issue in intellectual policy by settling the facts, whether by way of abductive theorizing or empirical investigation, no matter how reliable, is inapt. The (...) argument is a radicalization of Moore’s Open Question Argument. I conclude by considering the ramifications of this conclusion for the debate surrounding “Modal Security”, a proposed necessary condition on undermining defeat. (shrink)

The function and legitimacy of values in decision making is a critically important issue in the contemporary analysis of science. It is particularly relevant for some of the more application-oriented areas of science, specifically decision-oriented science in the field of regulation of technological risks. Our main objective in this paper is to assess the diversity of roles that non-cognitive values related to decision making can adopt in the kinds of scientific activity that underlie risk regulation. We start out, first, by (...) analyzing the issue of values with the help of a framework taken from the wider philosophical debate on science and values. Second, we study the principal conceptualizations used by scholars who have applied them to numerous case studies. Third, we appraise the links between those conceptualizations and learning processes in decision-oriented science. In this, we recur to the concept of methodological learning, i.e., learning about the best methodologies for generating knowledge that is useful for science-based regulatory decisions. The main result of our analysis is that non-cognitive values can contribute to methodological improvements in science in three principal ways: as basis for critical analysis, for contextualizing methodologies, and for establishing the burden of proof.

A conceptual analysis of falsificationism is performed, in which the central falsificationist thesis is divided into several components. Furthermore, an empirical study of falsification in science is reported, based on the 70 scientific contributions that were published as articles in Nature in 2000. Only one of these articles conformed to the falsificationist recipe for successful science, namely the falsification of a hypothesis that is more accessible to falsification than to verification. It is argued that falsificationism relies on an (...) incorrect view of the nature of scientific inquiry and that it is, therefore, not a tenable research methodology. (shrink)

One important trend in political philosophy is to hold that non-human animals don't directly place demands of justice on us. Another important trend is to give considerations of justice normative priority in our general normative theorising about social/political institutions. This situation is problematic, given the actual ethical standing of non-human animals. Either we need a theory of justice that gives facts about non-human animals a non-derivative explanatory role in the determination of facts about what justice involves, or else we should (...) be wary of the default normative priority that considerations of justice have in much of contemporary political philosophy. This discussion brings out important general methodological points tied to the role of concept and word choice in normative theorising about our social/political institutions. These methodological points, I argue, matter for a range of discussions in contemporary political philosophy, including those about global justice. (shrink)

This article argues that non-ideal theory is distinctive in its use of a certain methodology which is prior to specific topics (such as injustice, oppression, etc.), grounded in the idea of socially situated knowledge, and able to address ideological situatedness. Drawing on standpoint epistemology, we show that one’s social position within given power structures has implications for knowledge acquisition and that being in a vulnerable or marginalised position can be advantageous to knowledge acquisition. Following ideology critique, we argue that both (...) marginalised and powerful social positions are embedded within a given ideology. As ideology is more than a mere set of attitudes or beliefs that social agents endorse or resist, situated agents and theorists cannot develop normative criteria that are not themselves situated. Hence, non-ideal theory has to be equipped with methods that are likely to make this situatedness visible. We close by presenting some diverse methods that already do so. (shrink)

Readers of “Falsificationism Redux” (the rejoinder) may have found it to be another waffling non-explanation of induction and the alleged falsity of falsificationism—or even self-refuting, as its title indicates (redux: brought back, revived, restored). However, it seems worth another round of replies if only because the arguments are fairly typical of the would-be ‘inductivist’ and it might help some people who have yet to see how these arguments fail.

Modern methodology furnishes two partly competitive and partly complementary views on structure of the development of scientific investigation. According to the first view the development of science consists in enlargement of the set of empirical theorems; according to the other it consists, rather, in the narrowing of the set of possible theoretical hypotheses. A particular kind of assertion is associated with each of these views. The first is associated with the relation of assertion expressed in the statement: “the state α (...) of scientific investigationB forces us to accept the statement Τ”. The other view is associated with the relation of assertion expressed in the statement: “the state α of scientific investigationB admits the acceptance of the statement Τ”. Under a suitable definition of forcing we obtain the conclusion that intuitionistic logic is the class of only those formulas which we are forced to accept by every state of every scientific investigation. The notion of admission under a certain definition analogically leads to intuitionistic logic; on the other hand in the case of another, more natural definition, it leads to justification of a certain system of strict implication which is stronger than Lewis’ system S4 and which overlaps system S5.It can be said that assuming quite a natural definition of admission this system contains only those formulas the acceptance of which is admitted by every state of every scientific investigation.

The aim of this dissertation is to show that, if one is committed to the scientific worldview, one is thereby committed to ethical non-naturalism. In the first chapter I offer the reader an outline of the three primary domains of ethical inquiry: normative ethics, applied ethics, and meta-ethics. I commit myself to a meta-ethical thesis--ethical non-naturalism--and contrast ethical non-naturalism with its competitors. In the second chapter I offer a cursory defense of the moral realist's semantic thesis. I offer reason to (...) think the realist has the correct semantic account and argue against the semantic accounts offered by the realist's primary opponents. In the third chapter of the dissertation I argue that commitment to the scientific worldview requires that one think that the methods of the sciences provide privileged access to facts about the external world and I offer a brief sketch of inference to the best explanation--the primary method I will employ in offering a defense of ethical non-naturalism. In the fourth chapter I develop a method for identifying non-natural properties. The method relies heavily on the predictive power that can be gained by the accurate application of predicates. In the fifth chapter I apply the method developed in the previous chapter. The results are mixed. The method fails to demonstrate that there are non-natural moral facts; however, it does demonstrate that there are non-natural normative facts. Using this result as a lemma, I identify a hypothesis--"[H]"--that, if true, would vindicate ethical non-naturalism. In the sixth chapter I rely on [H] to respond to evolutionary criticisms of ethical non-naturalism and argue that, if morality evolved, we have good reason to believe [H]. In the final chapter, I defend the view I have developed from objections arising from the existence of moral disagreement and I argue that [H] provides the best explanation of the existence of actual moral disagreement.

Based on a rather simple thesis that we can learn from our mistakes, Karl Popper developed a falsificationist epistemology in which knowledge grows through falsifying, or criticizing, our theories. According to him, knowledge, especially scientific knowledge, progresses through conjectures that are controlled by criticism, or attempted refutations . As he puts it, ‘Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us understand the difficulties of the problem which we are trying to solve. (...) This is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory ... is always a step forward that takes us nearer to the truth. And this is how we can learn from our mistakes’ . Since criticism plays such a crucial role in Popper's falsificationist methodology, it seems natural to envisage his heuristic as a helpful resource for developing critical thinking. However, there is much controversy in the psychological literature over the feasibility and utility of his falsificationism as a heuristic. In this paper, I first consider Popper's falsificationism within the framework of his critical rationalism, elucidating three core and interrelated concepts, viz. fallibilism, criticism, and verisimilitude. Then I argue that the implementation of Popper's falsificationism means exposing to criticism various philosophical presuppositions that work against criticism, such as essentialism, instrumentalism, and conventionalism; it also means combating what seems a common tendency of humans to be biased towards confirmation. I examine the confirmation bias, to which Popper did not give much attention: its pervasiveness and various guises, some theoretical explanations for it, and the role of teachers in undermining its strength and spread. Finally, I consider the question whether students can and should be taught to use disconfirmatory strategies for solving problems. (shrink)

Focusing on some contemporary Islamic reformers’ solutions, in particular, Abolkarim Soroush, Mohsen Kadivar, and Fazlur Rahman, to concrete issues in Muslim societies, this article examines two different methodological strategies of alternative readings of the Sunna: an archeological one and a genealogical one. In the archeological perspective, the holy text has been considered as a repository of answers to all sorts of questions. Through a pathological analysis, this view suggests solutions to correct distortions and looks for new windows seeking an original (...) interpretation of the Qur’an. The genealogical view, on the other hand, puts aside this pathology and instead insists on the idea of the contingency of any interpretation. Regardless of accuracy and validity, according to the genealogical view, all interpretations have addressed temporal and contextual questions. What is important in this perspective is not returning to an original source for finding the exact message of Allah, or correcting previous interpretations, but recurrently referring to an open-ended text in order to explore the futures of the Qur’an.

Much ink has been spent on Popper's falsificationism. Why, then, am I writing another paper on this subject? This paper is neither a new kind of criticism nor a new kind of defense of falsificationism. Recent debate about the legitimacy of adaptationism among biologists centers on the question of whether Popper's falsificationism or Lakatos' methodology of scientific research programs (SRP) is adequate in understanding science. S. Jay Gould and Richard C. Lewontin (1978) argue that adaptationism is unfalsifiable since it easily (...) invites ad hoc adjustments when it makes false predictions. William A. Mitchell and Thomas J. Valone (1990) argue that adaptationism is a research program, and that the charge of falsifiability does not apply to a research program. Although both sides make use of the theories of scientific methodology proposed by Karl R. Popper (1934, 1957, 1963, 1971) and Imre Lakatos (1965, 1974, 1978), the differences and the similarities between these philosophers are overlooked. The purpose of the present paper is to explicate the differences and the similarities between the two philosophies of science. (shrink)

Problems of methodology are among the most acute in the modern scientific study of religion. As a result of the crisis of classical rationality, which, in particular, is a crisis of monologism and universalism of the mind, before the scientific research of religion, there was a need for the development of new paradigms and the problem of the unity of the methodology of religious studies. It should be noted the tendency to overcome the sociological regulations of religious studies, the search (...) for new approaches to comprehend the essence of religion. Using the terminology of T. Kuhn, we can say that the process of forming a new scientific paradigm is now under way, which is aimed at understanding not only the external forms of religion, or the solution of the problem of the functioning of religion in different cultures and in society, as much as religion as one of the essential structural elements of human existence.

This article examines the underlying problems of one particular perspective in educational theory that has recently gained momentum: the Wilfred Carr approach, which puts forward the premise that there is no theory in educational research and, consequently, it is a form of practice. The article highlights the scientific, epistemological and methodological assumptions inherent in such a view. The argument is developed as follows: first, it expounds what Carr understands by the methodology of action research and educational theory, setting out his (...) distinctive view. Secondly, it explains that both Carr's underlying methodology, as well as his theoretical alternative, are based on a particular perspective on Social Science. Thirdly, it reveals Carr's epistemological assumptions and the resultant educational consequences. (shrink)

Machine learning operates at the intersection of statistics and computer science. This raises the question as to its underlying methodology. While much emphasis has been put on the close link between the process of learning from data and induction, the falsificationist component of machine learning has received minor attention. In this paper, we argue that the idea of falsification is central to the methodology of machine learning. It is commonly thought that machine learning algorithms infer general prediction rules from (...) past observations. This is akin to a statistical procedure by which estimates are obtained from a sample of data. But machine learning algorithms can also be described as choosing one prediction rule from an entire class of functions. In particular, the algorithm that determines the weights of an artificial neural network operates by empirical risk minimization and rejects prediction rules that lack empirical adequacy. It also exhibits a behavior of implicit regularization that pushes hypothesis choice toward simpler prediction rules. We argue that taking both aspects together gives rise to a falsificationist account of artificial neural networks. (shrink)

Falsificationism has dominated 20th century philosophy of science. It seemed to have eclipsed all forms of inductivism. Yet recent debates have revived a specific form of eliminative inductivism, the basic ideas of which go back to F. Bacon and J.S. Mill. These modern endorsements of eliminative inductivism claim to show that progressive problem solving is possible using induction, rather than falsification as a method of justification. But this common ground between falsificationism and eliminative inductivism has not led to a detailed (...) investigation into the relationship, if any, which may exist between these two methodologies. This paper reviews several versions of eliminative inductivism, establishes a natural relation between eliminative inductivism and falsificationism, which derives from the distinction between models and theories, and carries out this investigation against a case study of the construction of atom models. The result of the investigation is that falsificationism is a form of eliminative inductivism in the limit of certain constraints. (shrink)

This paper considers non-standard analysis and a recently introduced computational methodology based on the notion of ①. The latter approach was developed with the intention to allow one to work with infinities and infinitesimals numerically in a unique computational framework and in all the situations requiring these notions. Non-standard analysis is a classical purely symbolic technique that works with ultrafilters, external and internal sets, standard and non-standard numbers, etc. In its turn, the ①-based methodology does not use any of these (...) notions and proposes a more physical treatment of mathematical objects separating the objects from tools used to study them. It both offers a possibility to create new numerical methods using infinities and infinitesimals in floating-point computations and allows one to study certain mathematical objects dealing with infinity more accurately than it is done traditionally. In these notes, we explain that even though both methodologies deal with infinities and infinitesimals, they are independent and represent two different philosophies of Mathematics that are not in a conflict. It is proved that texts :539–555, 2017; Gutman and Kutateladze in Sib Math J 49:835–841, 2008; Kutateladze in J Appl Ind Math 5:73–75, 2011) asserting that the ①-based methodology is a part of non-standard analysis unfortunately contain several logical fallacies. Their attempt to show that the ①-based methodology can be formalized within non-standard analysis is similar to trying to show that constructivism can be reduced to the traditional Mathematics.

In our century, the philosophy of science has been overshadowed by two towering figures: Popper and Wittgenstein, both Viennese emigrants, who have become subjects to the Queen (cf., e.g., Radnitzky [1987a] Entre Wittgenstein et Popper ... ). The discussion has been structured by two great controversies: from the 30s Popper versus logical positivism (or falsificationism versus verificationism/probabilism), and from the 60s 'the new philosophy of science' versus Critical Rationalism. (Exemplary contributions to thes two controversies can be found, e.g., in the (...) two collections Radnitzky and Andersson (eds.) [1978], Progress... Science, and [1979], Structure...Science.) Wittgenstein's Tractatus has been the idee directrice of the Vienna Circle and its successor, Logical Empiricism. The cynosure of 'the new philosophy of science' is Wittgenstein's later philosophy as presented, in particular, in his Philosophical Investigations. If you apply it to the philosophy of science, you will view 'normative' methodology as a counterpart of ideal language philosophy, and hence regard any methodological prescriptions as unrealistic and claim that philosophy of science cannot do more than describe the practice of science, preferably in terms of case studies culled from the history of science. You will be placed on the road to relativism (Kuhn, Feyerabend, Hiibner, and others). An interesting variant of relativism is Stegmiiller's attempt, with the help of the formal methods developed by Sneed, to give Kuhn's results a more exact form (Sneed, Stegmiiller, Moulines, Mostarin)-what Feyerabend has called 'the Sneedification of science'. Today, departments of philosophy of science are dominated by philosophers who either sympathize with logical empiricism or with 'the new philosophy of science'. Critical Rationalism has an outsider position, but enjoys the sympathy of many scientists (Bartley [1989], Unfathomed Knowledge .. .; see also Bartley [198 7b], 'Philosophy of biology ... ', and Munz [1987], ' ... the mirror of Rorty'). (shrink)

What methodology should philosophers follow? Should they rely on methods that can be conducted from the armchair? Or should they leave the armchair and turn to the methods of the natural sciences, such as experiments in the laboratory? Or is this opposition itself a false one? Arguments about philosophical methodology are raging in the wake of a number of often conflicting currents, such as the growth of experimental philosophy, the resurgence of interest in metaphysical questions, and the use of formal (...) methods. This outstanding collection of specially-commissioned chapters by leading international philosophers discusses these questions and many more. It provides a comprehensive survey of philosophical methodology in the most important philosophical subjects: metaphysics, epistemology, philosophy of language, philosophy of mind, phenomenology, philosophy of science, ethics, and aesthetics. A key feature of the collection is that philosophers discuss and evaluate contrasting approaches in each subject, offering a superb overview of the variety of methodological approaches - both naturalistic and non-naturalistic - in each of these areas. They examine important topics at the heart of methodological argument, including the role of intuitions and conceptual analysis, thought experiments, introspection, and the place that results from the natural sciences should have in philosophical theorizing. The collection begins with a fascinating exchange about philosophical naturalism between Timothy Williamson and Alexander Rosenberg, and also includes contributions from the following philosophers: Lynne Rudder Baker, Matt Bedke, Greg Currie, Michael Devitt, Matthew C. Haug, Jenann Ismael, Hilary Kornblith, Neil Levy, E.J. Lowe, Kirk Ludwig, Marie McGinn, David Papineau, Matthew Ratcliffe, Georges Rey, Jeffrey W. Roland, Barry C. Smith, Amie L. Thomasson, Valerie Tiberius, Jessica Wilson, and David W. Smith. (shrink)

In this paper I argue that neuroscience has been harmed by the widespread adoption of seriously inadequate methodologies or philosophies of science - most notably inductivism and falsificationism.

Das Problem, unter welchen Bedingungen eine Hypothese oder Theorienmodifikation als methodologisch akzeptabel gilt, wird in der wissenschaftstheoretischen Tradition als die Frage des Ad-Hoc-Charakters von Hypothesen diskutiert. Das gleichartige Problem tritt aber auch in Lakatos' Methodologie wissenschaftlicher Forschungsprogramme auf, welche von methodologisch zulässigen Theorienänderungen die Vorhersage 'neuer Tatsachen' verlangt. Über diesen Begriff der neuen Tatsache und damit der Adäquatheitsbedingungen für wissenschaftliche Erklärungen hat sich eine weitgefächerte Debatte entsponnen. In diesem Papier wird der Versuch unternommen, die Forderung der unabhängigen Testbarkeit einer Hypothese, (...) welche im Rahmen der Diskussion des Ad-hoc-Charakters von Hypothesen eine wichtige Rolle spielt, auch für die Frage der Spezifizierung von 'neuen Tatsachen' fruchtbar zu machen. Ich argumentiere zugunsten der Bedingung, daß eine Hypothese als methodologisch akzeptabel gelten sollte, wenn sie zumindest zwei unabhängige Tatsachen erklärt. Ein derartiger Ansatz verlangt die Kennzeichnung dessen, was als 'eine Tatsache' zu gelten hat. Die Schwierigkeit einer derartigen Kennzeichnung ist ein notorisches Problem jedes Kriteriums, das auf unabhängige Testbarkeit zielt. Eine Klärung dieses Problems wird über das Konzept der empirischen Generalisierung versucht. Als 'eine Tatsache' im methodologischen Sinne gilt demnach ein gesetzmäßiger Zusammenhang zwischen zwei Meßgrößen. Dies erlaubt weiterführend eine Klärung des Problems, was methodologisch als 'ein Experiment' zu werten ist, d. h. was als Reproduktion desselben und was als andersartiges Experiment gelten soll. Mit Hilfe dieser Klärungen wird unter anderem der Ad-hoc-Charakter der Lorentzschen Kontraktionshypothese sowie das Problem der Gleich- oder Verschiedenartigkeit von Michelson-Morley- und Kennedy-Thorndike-Experiment untersucht.

Karl R. Popper was a great admirer and friend of Hans Albert. What is it exactly that connected them? Answer to this question, barely a sketch, will also answer the question why and how I came to know Hans Albert. Within the normative methodological tradition set forth in Rene Descartes’ Regulae and Discourse on the Method, Karl R. Popper and Hans Albert converged on critical rationalism, the generalized version of Popper’s deductivist-falsificationist methodology of science.

The political theory of migration has largely occurred within a paradigm of methodological nationalism and this has led to the neglect of morally salient agents and causes. This article draws on research from the social sciences on the transnationalism, globalization and migration systems theory to show how methodological nationalist assumptions have affected the views of political theorists on membership, culture and distributive justice. In particular, it is contended that methodological nationalism has prevented political theorists of migration from addressing the roles (...) of non-state agents and of transnational economic, social and political structures. These agents and structures contribute to the asymmetrical distribution of goods and opportunities and thus have important implications for debates about migration and distributive justice. (shrink)

In the late 19th century, physiologists such as David Ferrier, Eduard Hitzig, and Hermann Munk argued that cerebral brain functions are localized in discrete structures. By the early 20th century, this became the dominant position. However, another prominent physiologist, Friedrich Goltz, rejected theories of cerebral localization and argued against these physiologists until his death in 1902. I argue in this paper that previous historical accounts have failed to comprehend why Goltz rejected cerebral localization. I show that Goltz adhered to a (...) falsificationist methodology, and I reconstruct how he designed his experiments and weighted different kinds of evidence. I then draw on the exploratory experimentation literature from recent philosophy of science to trace one root of the debate to differences in how the German localizers designed their experiments and reasoned about evidence. While Goltz designed his experiments to test hypotheses about the functions of predetermined cerebral structures, the localizers explored new functions and structures in the process of constructing new theories. I argue that the localizers relied on untested background conjectures to justify their inferences about functional organization. These background conjectures collapsed a distinction between phenomena they produced direct evidence for (localized symptoms) and what they reached conclusions about (localized functions). (shrink)

This article examines the methodology of a core branch of contemporary political theory or philosophy: “analytic” political theory. After distinguishing political theory from related fields, such as political science, moral philosophy, and legal theory, the article discusses the analysis of political concepts. It then turns to the notions of principles and theories, as distinct from concepts, and reviews the methods of assessing such principles and theories, for the purpose of justifying or criticizing them. Finally, it looks at a recent debate (...) on how abstract and idealized political theory should be, and assesses the significance of disagreement in political theory. The discussion is carried out from an angle inspired by the philosophy of science. (shrink)

Methodological naturalism arises as a topic in metaethics in two ways. One is the issue of whether we should be methodological naturalists when doing our moral theorising, and another is whether we should take a naturalistic approach to metaethics itself. Interestingly, these can come apart, and some naturalist programs in metaethics justify a non-scientific approach to our moral theorising. This paper discusses the range of approaches that fall under the general umbrella of methodological naturalism, and how naturalists view the role (...) of science in ethics and metaethics. It discusses how naturalism interacts with the use of intuitions, using conceptual analysis, and reflective equilibrium methods. Finally, it discusses some ways using scientific investigation can make distinctive contributions to ethics and metaethics. (shrink)

In this article we distinguish between philosophical bioethics (PB), descriptive policy orientated bioethics (DPOB) and normative policy oriented bioethics (NPOB). We argue that finding an appropriate methodology for combining empirical data and moral theory depends on what the aims of the research endeavour are, and that, for the most part, this combination is only required for NPOB. After briefly discussing the debate around the is/ought problem, and suggesting that both sides of this debate are misunderstanding one another (i.e. one side (...) treats it as a conceptual problem, whilst the other treats it as an empirical claim), we outline and defend a methodological approach to NPOB based on work we have carried out on a project exploring the normative foundations of paternal rights and responsibilities. We suggest that given the prominent role already played by moral intuition in moral theory, one appropriate way to integrate empirical data and philosophical bioethics is to utilize empirically gathered lay intuition as the foundation for ethical reasoning in NPOB. The method we propose involves a modification of a long-established tradition on non-intervention in qualitative data gathering, combined with a form of reflective equilibrium where the demands of theory and data are given equal weight and a pragmatic compromise reached.

Research in the subject area of economics (as a social science) has defined its ontologie of scientific investigation through economic methodology; a philosophical approach entailing the proviso of empirical evidence and backed by an understanding of human interaction in their natural habitat. The contention of economic methodology being refuted for its non-scientific means of investigation and particularly with the application of Ceteris Paribus (CP) law, has been critically addressed in this article, with Sierra Leone as a case example. Sierra Leone (...) is a complex economy and issues surrounding the assumption of CP has been brought to the fore, with a view of the political economy structure being made transparent so as to make it possible for economists to address critical issues surrounding corruption (exogenous factors), not accounted for in econometric modelling. This is not necessarily that which is considered as the most obvious, with the use of CP concept, for example, the influence of naturally occurring incidents like adverse weather conditions, flooding and earthquakes.

The aim of this paper is to examine the role of methodology in action research. It begins by showing how, as a form of inquiry concerned with the development of practice, action research is nothing other than a modern 20th century manifestation of the pre‐modern tradition of practical philosophy. It then draws in Gadamer's powerful vindication of the contemporary relevance of practical philosophy in order to show how, by embracing the idea of ‘methodology’, action research functions to sustain a distorted (...) understanding of what practice is. The paper concludes by outlining a non‐methodological view of action research whose chief task is to promote the kind of historical self‐consciousness that the development of practice presupposes and requires.
