Thirty years after the publication of Thomas Kuhn’s The Structure of Scientific Revolutions, sharp disagreement persists concerning the implications of Kuhn’s "historicist" challenge to empiricism. I discuss the historicist movement over the past thirty years, and the extent to which the discourse between two branches of the historical school has been influenced by tacit assumptions shared with Rudolf Carnap’s empiricism. I begin with an examination of Carnap’s logicism --his logic of science-- and his 1960 correspondence with Kuhn. I focus on (...) problems in the analysis applied to the unit of metascientific study or appraisal, arguing for a reassessment of historicist treatment of the internal/external distinction and historiographic meta-methodology. The critique of objectivism and relativism that eventuates from this re-assessment is a double-edged blade, undercutting both objectivist and relativist treatments of cognitive evaluation and scientific change. I use it to cut across an otherwise diverse group of historicist-influenced writers, including Imre Lakatos, Larry Laudan, H. M. Collins, Stephen Stich. I. Introduction.. (shrink)

Laudan's thesis that conceptual problem solving is at least as important as empirical problem solving in scientific research is given support by a study of the relation between the chromosome theory and the Mendelian research program. It will be shown that there existed a conceptual tension between the chromosome theory and the Mendelian program. This tension was to be resolved by changing the constraints of the Mendelian program. The relation between the chromosome theory and the Mendelian program is shown to (...) be a good illustration of the influence of science itself on the rational standards governing scientific development.

Summary For Imre Lakatos hismethodology of scientific research programmes was not only a philosophical theory of science and scientific change but also the conceptual foundation of empirical and historical studies of science. At least terminologically this view is today widely accepted: The concept of aresearch programme is used in all sorts of literature on science. In the present paper I argue that this concept can lead to serious distortions of empirical and historical studies of science if it is not detached (...) from the Lakatosian philosophical framework. Themethodology of scientific research programmes has three main pitfalls, which may lead to disorientations of empirical and historical studies of science: (1) Contrary to what the term research programme may suggest, it offers no perspective on scientific research as an object of analysissui generis; (2) its concept of science is too narrow and covers only minor parts of what counts as science in the real world; (3) it reduces history of science to a mere sequence of research programmes and thereby eliminates the fact that there is an evolution of the structure of research programmes, too.

Research Programme and Development of Science. For Imre Lakatos his methodology of scientific research programmes was not only a philosophical theory of science and scientific change but also the conceptual foundation of empirical and historical studies of science. At least terminologically this view is today widely accepted: The concept of a research programme is used in all sorts of literature on science. In the present paper I argue that this concept can lead to serious distortions of empirical and historical studies (...) of science if it is not detached from the Lakatosian philosophical framework. The methodology of scientific research programmes has three main pitfalls, which may lead to disorientations of empirical and historical studies of science: (1) Contrary to what the term "research programme" may suggest, it offers no perspective on scientific research as an object of analysis sui generis; (2) its concept of science is too narrow and covers only minor parts of what counts as science in the real world; (3) it reduces history of science to a mere sequence of research programmes and thereby eliminates the fact that there is an evolution of the structure of research programmes, too.

Some peculiarities of the evaluation of theories within scientific research programmes (SRPs) and of the assessing of rival SRPs are described assuming that scientists try to maximise an 'epistemic utility function' under economic and institutional constraints. Special attention is given to Lakatos' concepts of 'empirical progress' and 'theoretical progress'. A notion of 'empirical verisimilitude' is defended as an appropriate utility function. The neologism 'methodonomics' is applied to this kind of studies.

Cognitive architectures - task-general theories of the structure and function of the complete cognitive system - are sometimes argued to be more akin to frameworks or belief systems than scientific theories. The argument stems from the apparent non-falsifiability of existing cognitive architectures. Newell was aware of this criticism and argued that architectures should be viewed not as theories subject to Popperian falsification, but rather as Lakatosian research programs based on cumulative growth. Newell's argument is undermined because he failed to demonstrate (...) that the development of Soar, his own candidate architecture, adhered to Lakatosian principles. This paper presents detailed case studies of the development of two cognitive architectures, Soar and ACT-R, from a Lakatosian perspective. It is demonstrated that both are broadly Lakatosian, but that in both cases there have been theoretical progressions that, according to Lakatosian criteria, are pseudo-scientific. Thus, Newell's defense of Soar as a scientific rather than pseudo-scientific theory is not supported in practice. The ACT series of architectures has fewer pseudo-scientific progressions than Soar, but it too is vulnerable to accusations of pseudo-science. From this analysis, it is argued that successive versions of theories of the human cognitive architecture must explicitly address five questions to maintain scientific credibility. (shrink)

This paper concerns the problem of how to give historical explanations of scientist's decisions to prefer one theory over another. It is argued that such explanations ought to contain only statements about the beliefs and preferences of the agents involved, and, in particular, ought not to include evaluative premises about the theories themselves. It is argued that Lakatos's attempt to build into such historical explanations premises of an evaluative kind is deficient. The arguments of Laudan to the effect that such (...) explanations depend crucially upon evaluative assumptions about the rationality or irrationality of decisions are examined. It is argued that they do not establish the need for such assumptions. Similar criticisms are then shown to be applicable to a version of the 'hermeneutical' model of explanation for human actions.

A case study of the development of quantum field theory and of S-matrix theory, from their inceptions to the present, is presented. The descriptions of science given by Kuhn and by Lakatos are compared and contrasted as they apply to this case study. The episodes of the developments of these theories are then considered as candidates for competing research programs in Lakatos' methodology of scientific research programs. Lakatos' scheme provides a reasonable overall description and a plausible assessment of the relative (...) value of these two programs in terms of progressive and degenerating problem shifts. Also discussed are the roles of various types of models as they have been used in these areas of theoretical high-energy physics. (shrink)

In this paper I assess the obstacles to a transfer of Lakatos's methodology of scientific research programmes to mathematics. I argue that, if we are to use something akin to this methodology to discuss modern mathematics with its interweaving theoretical development, we shall require a more intricate construction and we shall have to move still further away from seeing mathematical knowledge as a collection of statements. I also examine the notion of rivalry within mathematics and claim that this appears to (...) be significant only at a high level. In addition, ideas of ‘progress’ in mathematics are outlined.

Over the past thirty years Paul Feyerabend has developed an extremely distinctive and influentical approach to problems in the philosophy of science. The most important and seminal of his published essays are collected here in two volumes, with new introductions to provide an overview and historical perspective on the discussions of each part. Volume 1 presents papers on the interpretation of scientific theories, together with papers applying the views developed to particular problems in philosophy and physics. The essays in volume (...) 2 examine the origin and history of an abstract rationalism, as well as its consequences for the philosophy of science and methods of scientific research. Professor Feyerabend argues with great force and imagination for a comprehensive and opportunistic pluralism. In doing so he draws on extensive knowledge of scientific history and practice, and he is alert always to the wider philosophical, practical and political implications of conflicting views. These two volumes fully display the variety of his ideas, and confirm the originality and significance of his work. (shrink)

Abstract The paper is an attempt to interpret Imre Lakatos's methodology of scientific research programmes (MSRP) on the basis of his mathematical methodology, the method of proofs and refutations (MPR). After sketching MSRP and MPR and analysing their relationship to Popper's and Poly a's work, I argue that MSRP was originally conceived as a methodology in the same sense as MPR. The most conspicuous difference between the two, namely that MSRP is fundamentally backward?looking, whereas MPR is primarily forward?looking, is due (...) to the fact that Lakatos could not carry out his project in the full sense. I also explain why he could not. (shrink)

In the first part of this article I investigated the Popperian roots of Lakatos's Proofs and Refutations, which was an attempt to apply, and thereby to test, Popper's theory of knowledge in a field-mathematics-to which it had not primarily been intended to apply. While Popper's theory of knowledge stood up gloriously to this test, the new application gave rise to new insights into the heuristic of mathematical development, which necessitated further clarification and improvement of some Popperian methodological maxims. In the (...) present part I analyze this second phase in the development of Lakatos's Popperian programme in mathematics, and its connection to the methodology of scientific research programmes. (shrink)

In this paper I explore possibilities of bringing post-positivist philosophies of empirical science to bear on the dynamics of mathematical development. This is done by way of a convergent accommodation of a mathematical version of Lakatos's methodology of research programmes, and a version of Kuhn's account of scientific change that is made applicable to mathematics by cleansing it of all references to the psychology of perception. The resulting view is argued in the light of two case histories of radical conceptual (...) innovations. (shrink)

Sometimes themes can be found in common across very different systems in which change occurs. Imre Lakatos developed a theory of change in science, and one involving entities visible at different levels. There are theories defended at a particular time, and there are also research programs, larger units that bundle together a sequence of related theories and within which many scientists may work. Research programs are competing higher-level units within a scientific field. Scientific change involves change within research programs, and (...) change in the ensemble of research programs present at a time, where some will be growing, some shrinking, some progressing, some degenerating. These are also themes in biological evolution. Recent biology has often found itself dealing with the relation between change at a level of "collectives" – such as organisms like us – and change at a lower level – the level of cells, genes, and other evolving parts. This work is continuous with an older discussion, one that arose when biological evolution was no more than a vague speculation, round the beginning of the 19th century. What is the living individual? What is the basic unit of life or living organization? Questions like this were pursued by Goethe, by Erasmus Darwin, the grandfather of Charles, and many others. Initially it was plants, especially, that were seen to raise these problems, and then newly described marine animals with strange life cycles. The discussion was influenced by the rise of the cell theory in the early 19th century, but some writers looked for individuals well below the level of the cell. (shrink)

Lakatos’s approach to prediction and novel facts is of considerable interest. Prediction appears in his conception in at least three different levels: a) as an important aim of the research programs; b) as a procedure -a key method- for increasing our scientific knowledge both theoretically and empirically; and c) as the way to assess the scientific character of knowledge claims -means for evaluating results-. At all these levels he envisions a close connection between prediction and novel facts. The paper has (...) four aims. First, to examine his concept of “prediction” in Lakatos’s MSRP, taking into account different aspects (semantical, logical, epistemological, methodological and axiological). Second, to clarify the notion of “novel facts”, which requires the consideration of the various ways in which new facts can be understood. Third, to examine the prediction of novel facts as criterion of appraisal (theoretical, empirical and heuristical). Fourth, to explore Lakatos’s approach (i.e., the concept of prediction linked to novel facts) in connection with the field of economics, in order to shed new light on issues that have been discussed in recent years.

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)

This note is intended to address one particular issue in the relative status of Quantum Chemistry in comparison to both Chemistry and Physics. It has been suggested, in the context of the question of the reduction relations between Chemistry and Physics that Quantum Chemistry as a research programme is incapable of furnishing useful guidance to practising chemists. If true, this claim will let us qualify Quantum Chemistry as a degenerating research programme, which, due to its complexity has difficulty to be (...) applied to Chemistry. This claim is shown to be false. The replacement claim I wish to make is that Quantum Chemistry is perfectly capable of furnishing such guidance, but renders the ontological status of many models favored by chemists problematic. Quantum Chemistry, however, validates these models in an instrumental fashion. I will argue that Quantum Chemistry is a progressive research programme. (shrink)

In this paper a model is presented for the growth of knowledge in a dynamic scientific system. A system which is in some respects an idealization of a Lakatosian research program. The kinematics of the system is described in terms of two probabilistic variables, one of which is related to the evolution of its theoretical component and the other--to the growth of the empirical component. It is shown that when the empirical growth is faster than the theoretical growth the posterior (...) probability of the theoretical component increases. Thus, empirical progressiveness of a research program, as explicated in this model, is accompanied by an increase in the degree of confirmation. In such a case the system grows in a Popperian-like spirit, while learning from experience in a Bayesian manner. (shrink)

Heuristic is a central concept of Lakatos' philosophy both in his early works and in his later work, the methodology of scientific research programs (MSRP). The term itself, however, went through significant change of meaning. In this paper I study this change and the ‘metaphysical' commitments behind it. In order to do so, I turn to his mathematical heuristic elaborated in Proofs and Refutations. I aim to show the dialogical character of mathematical knowledge in his account, which can open a (...) door to hermeneutic studies of mathematical practice. (shrink)

Research programmes are sets of problems preferred on epistemic grounds and including preferred heuristics for inquiry. Charles Lyell's research programme for biogeograpy includes the problem of explaining the distribution of species constrained by laws governing locomotion and containment of species. Included in the programme are laws governing the supernatural introduction of replacement species. Wallace and Darwin derected arguments against the putative intelligibility of this aspect of Lyell's programme before discovering natural selection, and their defence, at this time of natural laws (...) governing the introduction of new species is interesting as a defence of a noval programme of research, not a defence of a proposed theroy. These arguments are presented and an epistemological foundation is offered for them. 1 The author is indebted to a referee for helpful comments on an earlier draft of this paper. (shrink)

Popper has provided a model for the scientific explanation of human actions and a metaphysical theory of man which can guide scientific research. In this paper I discuss the problems of the empirical content and nomicity of the Rationality Principle and extend the method of situational analysis to the problem of explaining beliefs. The domain of applicability of the Rationality Principle is bounded on one side by cases in which behavior is determined by processes which can not be influenced by (...) criticism and on the other side by the phenomenon of substantive creativity. However, a large part of human activity lies within its scope. (shrink)

Imre Lakatos' philosophical and scientific papers are published here in two volumes. Volume I brings together his very influential but scattered papers on the philosophy of the physical sciences, and includes one important unpublished essay on the effect of Newton's scientific achievement. Volume II presents his work on the philosophy of mathematics (much of it unpublished), together with some critical essays on contemporary philosophers of science and some famous polemical writings on political and educational issues. Imre Lakatos had an influence (...) out of all proportion to the length of his philosophical career. This collection exhibits and confirms the originality, range and the essential unity of his work. It demonstrates too the force and spirit he brought to every issue with which he engaged, from his most abstract mathematical work to his passionate 'Letter to the director of the LSE'. Lakatos' ideas are now the focus of widespread and increasing interest, and these volumes should make possible for the first time their study as a whole and their proper assessment. (shrink)

Lakatos: An Introduction is the first comprehensive analysis on the intellectual life and theories of the distinguished thinker Imre Lakatos. This book clearly presents Lakatos's development of a philosophy of mathematics and empirical science, Lakatos's thought as an important hybrid of Popperian philosophy and Hegelian-Marxist thought, the relationship between Lakatos's views on science and mathematics and his more general philosophical beliefs. Brendan Larvor clearly locates Lakatos in the liberal-rationalist tradition and explains connections between the philosopher's life, philosophy, politics, and technical (...) work in science and mathematics.

Marian Przełęcki’s semantics for the Received View is a good explication of Carnap’s position on the subject, anticipates many discussions and results from both proponents and opponents of the Received View, and can be the basis for a thriving research program.

Imre Lakatos’ idea that history of science without philosophy of science is blind may still be given a plausible interpretation today, even though his theory of the methodology of scientific research programmes has been rejected. The latter theory captures neither rationality in science nor the sense in which history must be told in a rational fashion. Nonetheless, Lakatos was right in insisting that the discipline of history consists of written rational reconstructions. In this paper, we will examine possible ways to (...) cash out different, philosophically interesting, relationships: between rationality and science, between rationality and philosophy of science and/or epistemology, and, of course, between history and philosophy of science. Our conclusion is that the historian of science may be a philosopher of science as weIl, but if that philosophy of science is essentially a historical and dogmatic, it either cannot be used for history or it will deprive history of some of its most interesting and useful categories.

Although, when first introduced, Copernicus's theory considered as a whole was not superior to the Ptolemaic theory according to any of the usual criteria for comparing theories and determining their acceptability, it did have features which provided the early Copernicans with good reasons for entertaining it and trying to develop it further. These features are discussed and then three plausibility considerations which seem to be operative in this case are formulated.

Here is a dilemma concerning the history of science. Can the history of scientific thought be reduced to the history of the beliefs, motives and actions of scientists? Or should we think of the history of scientific thought as in some sense independent from the history of scientists? The aim of this paper is to carve out an intermediate position between these two. I will argue that the history of scientific thought supervenes on, but not reducible to, the history of (...) scientists. There is a legitimate level of description for analyzing the history of scientific thought that does not reduce to the individual level of scientists. Yet, every aspect of the history of scientific thought is determined by the actual motives and actions of individual scientists. Maybe surprisingly, I use Imre Lakatos’s controversial concept of the rational reconstruction of the history of science in order to argue for this intermediate position. (shrink)

Recent research shows that research programmes (quantitative, qualitative and mixed) in education are not displaced (as suggested by Kuhn) but rather lead to integration. The objective of this study is to present a rationale for mixed methods (integrative) research programs based on contemporary philosophy of science (Lakatos, Giere, Cartwright, Holton, Laudan). This historical reconstruction of episodes from physical science (spanning a period of almost 300 years, 17 th to 20 th century) does not agree with the positivist image of science. (...) Quantitative data (empirical evidence) by itself, does not facilitate progress (despite widespread belief to the contrary), neither in the physical sciences nor in the social sciences (education) A historical reconstruction shows that both Piaget and Pascual-Leone's research programs in cognitive psychology, follow the Galilean idealisation quite closely, similar to the research programs of Newton, Mendeleev, Einstein, Thomson, Rutherford, Millikan and Perl in the physical sciences. This relationship does not imply that researchers in education have to emulate research in the physical sciences. A major argument in favor of mixed methods (integrative) research programs is that it provides a rationale for hypotheses, theories, guiding assumptions and presuppositions to compete and provide alternatives. Similar to the physical sciences, this proliferation of hypotheses leads to controversies and rivalries, and thus facilitates the decision making process of the scientific community. It is concluded that mixed methods research programs (not paradigms) in education can facilitate the construction of robust strategies, provided we let the problem situation (as studied by practicing researchers) decide the methodology.

Summary This paper presents an immanent criticism of Lakatos' reconstruction of the degenerating phase of Bohr's atomic theory. That is to say, the historiographical methods used are exclusively of a Lakatosian kind. Such a closer Lakatosian look at the historical episode in question shows that Lakatos' own reconstruction is incorrect on three essential points. These are the role of the correspondence principle, the position of the hard core in Bohr's programme, and the presence of important novel predicted facts. I conclude (...) that these defects are irreparable within the framework of Lakatos' methodology of scientific research programmes. (shrink)

The problem of the critical assessment of theories across paradigms raised by Kuhn is not resolved, it is argued, either by Scheffler's appeal to initial credibility or by Lakatos' conception of a research program. It is argued further that, in these contexts, the notion of reasonable choice by individuals makes no sense. The conclusion supports Feyerabend's position of "epistemological anarchism.".

This paper addresses the intellectual motivation of some of those involved in the intelligent design movement. It identifies their concerns with the critique of the claim that Darwinism offers an adequate explanation of prima facie teleological features in biology, a critique of naturalism, and the concern on the part of some of these authors including Dembski, with the revival of 'Old Princeton' apologetics. It is argued that their work is interesting and is in principle intellectually legitimate. It is also suggested, (...) however, that it needs to be appraised qua 'research programme' (after the fashion of the early work of Lakatos), and that, seen in that light, what needs to be accomplished might seem daunting.

This book offers a distinctive treatment of Hayek's ideas as a "research program". It presents a detailed account of aspects of Hayek's intellectual development and of problems that arise within his work, and then offers some broad suggestions as to ways in which the program initiated in his work might be developed further. The book discusses how Popper and Lakatos' ideas about "research programs" might be applied within political theory. There then follows a distinctive presentation of Hayek's intellectual development up (...) to The Road to Serfdom, together with critical engagement with his later ideas. The discussion draws on a full range of his writings, makes use of some neglected earlier work on social theory and law, and also draws on archival material. This book should appeal to anyone with an interest in Hayek's work, as well as to those with a concern for twentieth century intellectual history. (shrink)

economists. According to Rosenberg, Milton Friedman's positive methodology is being supplanted by Lakatos's methodology of scientific research programs (MSRP). At any rate, the Kuhnian wave of the seventies is being swallowed up by the Lakatosian program. (Redman 142) There have been a number of attempts to comprehend mainstream (bourgeois) economics as a Lakatosian research program, or as a set of competing research programs. (Latsis, ed. passim; de Marchi and Blaug, eds.)i In contrast, the extent to which the Marxian study of (...) capitalism can be interpreted from this perspective has hardly been explored.ii In the following sections some provisional steps in this direction will be taken. I shall first introduce a reading of Marx's Capital that emphasizes the systematic dialectic of economic categories unifying that work. I shall then ask whether we can arrive at a better understanding of Marx's systematic dialectic through considering how it contributes to a scientific research 1 program in Lakatos's sense of the term. Two other themes will arise along the way. Certain shortcomings in Lakatos's framework will be discussed. Also, a number of reasons for considering the Marxian research program superior to that of neoclassical economics will be mentioned. It should be stressed that the main topic of the present paper is the role of systematic dialectics in the Marxian research program. The other themes go far beyond the scope of single paper. Lakatos's work can be understood as a response to the dead-end of naive falsificationism. According to this simplistic methodology, theories are to be tested by deducing predictions from them and then determining whether the events predicted occur. If the predicted events do take place at some later time, this does not verify the validity of the theory. That would be to commit the fallacy of affirming the consequent; there may be many other theories that also lead to the prediction in question. In contrast, if the predicted events do not take place, that is sufficient to falsify the proposed theory.. (shrink)

Why did Copernicus's research programme supersede Ptolemy's?’, Lakatos and Zahar argued that, on Zahar's criterion for ‘novel fact’, Copernican theory was objectively scientifically superior to Ptolemaic theory. They are mistaken, Lakatos and Zahar applied Zahar's criterion to ‘a historical thought-experiment’—fictional rather than real history. Further, in their fictional history, they compared Copernicus to Eudoxus rather than Ptolemy, ignored Tycho Brahe, and did not consider facts that would be novel for geostatic theories. When Zahar's criterion is applied to real history, the (...) results are distinctly different. Finally, most of the historical and conceptual problems in applying Zahar's criterion to the Copernican Revolution primarily arise from a deep difficulty in Lakatos's programme: the necessity of individuating research programmes and identifying their originators. 1 Working closely with David Dahl was crucial in developing this paper. Robert Westman's valiant effort to keep me on the historical straight and narrow drastically limited my tendency to a priori historical pronouncements. The Vassar Philosophy Department, John Tompsich, and Jean Sterling were also helpful. (shrink)

In this paper we show that any reasoning process in which conclusions can be both fallible and corrigible can be formalized in terms of two approaches: (i) syntactically, with the use of defeasible reasoning, according to which reasoning consists in the construction and assessment of arguments for and against a given claim, and (ii) semantically, with the use of partial structures, which allow for the representation of less than conclusive information. We are particularly interested in the formalization of scientific reasoning, (...) along the lines traced by Lakatos’ methodology of scientific research programs. We show how current debates in cosmology could be put into this framework, shedding light on a very controversial topic. (shrink)

Bernard Lavor and John Kadvany argue that Lakatos’s Hegelian approach to the philosophy of mathematics and science enabled him to overcome all competing philosophies. His use of the approach Hegel developed in his Phenomenology enabled him to show how mathematics and science develop, how they are open-ended, and that they are not subject to rules, even though their rationality may be understood after the fact. Hegel showed Lakatos how to falsify the past to make progress in the present. A critique (...) based on normal standards of fairness and honesty finds this argument an attack on rationality. The similarity of the methods Lakatos used as a Stalinist politician and those he used as a philosopher are pointed out. The Hegelian interpretation of his philosophy is an excuse for his misdeeds. Key Words: Lakatos • Popper • Agassi • research program • historiography. (shrink)

It has often been argued, by philosophers and more recently by developmental psychologists, that our common-sense conception of the mind should be regarded as a scientific theory. However, those who advance this view rarely say much about what they take a scientific theory to be. In this paper, I look at one specific proposal as to how we should interpret the theory view of folk psychology--namely, by seeing it as having a structure analogous to that of a Lakatosian research program. (...) I argue that although the Lakatosian model may seem promising--particularly to those who are interested in studying the development of children's understanding of the mind--the analogy between Lakatosian research programs and folk psychology cannot be made good because folk psychology does not possess anything analogous to the positive heuristic of a Lakatosian research program. I also argue that Lakatos' account of theories may not be the best one for developmental psychologists to adopt because of the emphasis which Lakatos places on the social embeddedness of scientific theorising. (shrink)

In this paper I try to explain why Lakatos’s (and Popper’s) conventionalist view must be replaced by a phenomenological conception of the empirical basis; for only in this way can one make sense of the theses that the hard core of an RP (Research Programme) can be shielded against refutations; that this metaphysical hard core can be turned into a set of guidelines or, alternatively, into a set of heuristic metaprinciples governing the development of an RP; and that a distinction (...) can legitimately be made between novel predictions and facts to which a theory might have been adjusted post hoc. Two basic metaprinciples are finally examined: the (conservative) Correspondence Principle and various (revolutionary) symmetry requirements; both of these heuristic devices illustrate the fundamental role which, according to Lakatos, mathematics plays in the progress of empirical science.

Gerhard Schurz [2001, Journal for General Philosophy of Science, 32, 65-107] has proposed to reconstruct auxiliary hypothesis addition, e.g., postulation of Neptune to immunize Newtonian mechanics, with concepts from non-monotonous inference to avoid the retention of false predictions that are among the consequence-set of the deductive model. However, the non-monotonous reconstruction retains the observational premise that is indeed rejected in the deductive model. Hence, his proposal fails to do justice to Lakatos' core-belt model, therefore fails to meet what Schurz coined (...) "Lakatos' challenge". It is argued that Lakatos's distinction between core and belt of a research program is not mapable onto premise-set and consequence-set and that Schurz's understanding of a ceteris paribus clause as a transfinite list of (absent) interfering factors is problematic. I propose a simple reading of Lakatos's use of the term ceteris paribus clause and motivate why the term hypothesis addition, despite not being interpretable literally, came to be entrenched. (shrink)
