Dynamics of scientific change and cognitive science. An epistemological update / Dinámica de cambio y ciencias cognitivas. Una puesta al día epistemológica

Abstract

I explore two proposals on the dynamics of scientific change in the general philosophy of science and I evaluate the extent to which they can be applied in the cognitive sciences. I do this by paying special attention to the youth and diversity which characterize this field of scientific research. Firstly, I distinguish two kinds of uses of Kuhn’s work: direct but loose applications of Kuhnean concepts to the history of cognitive science, on the one hand, and indirect applications of certain aspects of Kuhnean ideas, on the other hand. Secondly, I criticize their pertinence on the basis of the secondary role which theories play in the field. Finally, I defend the fertility of the concept of ‘research tradition’ proposed by Laudan, by focusing on the previously highlighted set of idiosyncratic characteristics of the cognitive sciences.     

The Future of The Structure of Scientific Revolutions

I examine the value and limitations of Kuhn’s Structure of Scientific Revolutions. In the interests of developing a social epistemology of science, I argue that we should draw on Kuhn’s later work, published in The Road since Structure. There, Kuhn draws attention to the important role that specialty formation plays in resolving crises in science, a topic he did not discuss in Structure. I argue that we need to develop a better understanding of specialty research communities. Kuhn’s later work provides a research agenda for those who want to study scientific specialization. I briefly discuss some recent studies that promise to provide valuable insight into the social structure of science.     

Is open-mindedness truth-conducive?

What makes an intellectual virtue a virtue? A straightforward and influential answer to this question has been given by virtue-reliabilists: a trait is a virtue only insofar as it is truth-conducive. In this paper I shall contend that recent arguments advanced by Jack Kwong in defence of the reliabilist view are good as far as they go, in that they advance the debate by usefully clarifying ways in how best to understand the nature of open-mindedness. But I shall argue that these considerations do not establish the desired conclusions that open-mindedness is truth-conducive. To establish these much stronger conclusions we would need an adequate reply to what I shall call Montmarquet’s objection. I argue that Linda Zagzebski’s reply to Montmarquet’s objection, to which Kwong defers, is inadequate. I conclude that it is contingent if open-mindedness is truth-conducive, and if a necessary tie to truth is what makes an intellectual virtue a virtue, then the status of open-mindedness as an intellectual virtue is jeopardised. We either need an adequate reliabilist response to Montmarquet’s objection, or else seek alternative accounts of what it is that makes a virtue a virtue. I conclude by briefly outlining some alternatives.

     

Stabilizing and Changing Phenomenal Worlds: Ludwik Fleck and Thomas Kuhn on Scientific Literature

In the work of both Ludwik Fleck and Thomas Kuhn the scientific literature plays important roles for stability and change of scientific phenomenal worlds. In this article we shall introduce the analyses of scientific literature provided by Fleck and Kuhn, respectively. From this background we shall discuss the problem of how divergent thinking can emerge in a dogmatic atmosphere. We shall argue that in their accounts of the factors inducing changes of scientific phenomenal worlds Fleck and Kuhn offer substantially different approaches, and we shall discuss in which respects their approaches may be compatible. This revised version was published online in August 2006 with corrections to the Cover Date.     

Explaining the Success of Science: Kuhn and Scientific Realists

In this essay, I critically evaluate the approaches to explaining the success of science in Kuhn and the works of inference-to-the-best-explanation scientific realists. Kuhn’s challenge to realists, who invoke the truth of theories to explain their success, is two-fold. His paradigm-account of success confronts realists with the problem of theory change, and the historical fact of successful theories later rejected as false. Secondly, Kuhn’s account of the success of science has no need to bring truth into the explanation. In turn, I argue that weakness in Kuhn and the prevailing forms of scientific realism motivate a better account of realism which I characterize as ‘best current theory realism’ and defend against the pessimistic meta-induction and the problem of theory-change. This realism argues that the best explanation of the success of current and past scientific theories only requires the simple claim that our best current theories are true. Kuhn’s account can explain how normal science succeeds but cannot account for why its problem solutions work where they do and why they fail for other puzzles.     

Against the Politics of Postmodern Philosophy of Science

This paper discusses the tenets of the politics of postmodern philosophy of science. At issue are Rouse’s version of naturalism and his reading of Quine’s distinction between the indeterminacy of translation and the underdetermination of theories by empirical evidence. I argue that the postmodern approach to science’s research practices as patterns of interaction within the world is not in line with the naturalistic account Rouse aims at. I focus also on Rouse’s readings of Heidegger’s existential conception of science and Kuhn’s concept of normal science. Finally, a strategy of defending science’s cognitive distinctiveness in terms of hermeneutic philosophy is suggested as an alternative to the postmodern philosophy of science.     

TENSIONS IN INTELLIGENT DESIGN'S CRITIQUE OF THEISTIC EVOLUTIONISM

“Intelligent Design” (ID) is a contemporary intellectual movement arguing that there is scientific evidence for the existence of some sort of creator. Its proponents see ID as a scientific research program and as a way to build a bridge between science and theology, while many critics see it merely as a repackaged form of religiously motivated creationism: both bad science and bad theology. In this article, I offer a close reading of the ID movement's critique of theistic evolutionism and argue that this critique is ultimately in tension with the movement's broader thought.     

The Social Authority of Paradigms as Group Commitments: Rehabilitating Kuhn with Recent Social Philosophy

By linking the conceptual and social dynamics of change in science, Kuhn’s Structure of Scientific Revolutions proved tremendously fruitful for research in science studies. But Kuhn’s idea of incommensurability provoked strong criticism from philosophers of science. In this essay I show how Raimo Tuomela’s Philosophy of Sociality illuminates and strengthens Kuhn’s model of scientific change. After recalling the central features and problems of Kuhn’s model, I introduce Tuomela’s approach. I then show (a) how Tuomela’s conception of group ethos aligns with Kuhn’s notion of paradigms as group commitments, and (b) how Tuomela’s distinction between I-mode and we-mode forms of collective intentionality can capture the shifting paradigmatic commitments in Kuhn’s model of change as a cycle of normal and revolutionary science. But Tuomela’s analysis does not rely on meaning holism, and thus does not involve the problematic notion of incommensurability that burdened Kuhn’s analysis.     

On Typologies for Relating Science and Religion

Geoffrey Cantor and Chris Kenny have criticized attempts to classify various ways of relating science and religion. They hold that all typologies are too simple and too static to illuminate the complex and changing historical interactions of science and religion. I argue that typologies serve a useful pedagogical function even though every particular interaction must be seen in its historical context. I acknowledge the problems in making distinctions between categories of classification and examine some alternative typologies that have been proposed. I leave as an open question whether my fourfold typology is applicable to differing religious traditions. Finally I consider some parallels between typologies for science‐religion interactions and typologies for relationships between religions. Can our discussions be both interdisciplinary and interreligious without the danger of imposing the conceptual framework of one discipline or religious tradition on another discipline or tradition?     

Alasdair MacIntyre's Analysis of Tradition

I argue that, in analysing the structure and development of moral traditions, MacIntyre relies primarily on Kuhn's model of scientific tradition, rather than (as is held by at least two influential commentators) on Lakatos' model. I unpack three foci of Kuhn's conception of the sciences, namely: the ‘crisis’ conception of scientific development, what I call the ‘systematic conception’ of scientific paradigms, and the view that successive paradigms are incommensurable. I then show that these three foci are integrated into MacIntyre's account of the development of moral traditions with a surprising degree of faithfulness to Kuhn. And crucially, I argue against the overall cogency of his account, given the disparities I pinpoint between scientific and moral traditions. My overall critique is, however, fundamentally friendly, since nothing I have to say invalidates the very notion of a moral tradition, and all I am calling for are less problematic construals of that notion.     

Radical views on cognition and the dynamics of scientific change

Radical views on cognition are generally defined by a cluster of features including non-representationalism and vehicle-externalism. In this paper, I concentrate on the way radical views on cognition define themselves as revolutionary theories in cognitive science. These theories often use the Kuhnian concepts of “paradigm” and “paradigm shift” for describing their ambitions and the current situation in cognitive science. I examine whether the use of Kuhn’s theory of science is appropriate here. There might be good reasons to think that cognitive science is in a situation of foundational crisis, but that does not entail that the classical paradigm (computationalism) is currently displaced to the benefit of a new paradigm. Larry Laudan’s theory of research traditions is more enlightening than Kuhn’s theory for describing the scope and ambitions of radical views on cognition, and their relations with an anti-intellectualist tradition in philosophy.

     

Unification and Revolution: A Paradigm for Paradigms

Incommensurability was Kuhn’s worst mistake. If it is to be found anywhere in science, it would be in physics. But revolutions in theoretical physics all embody theoretical unification. Far from obliterating the idea that there is a persisting theoretical idea in physics, revolutions do just the opposite: they all actually exemplify the persisting idea of underlying unity. Furthermore, persistent acceptance of unifying theories in physics when empirically more successful disunified rivals can always be concocted means that physics makes a persistent implicit assumption concerning unity. To put it in Kuhnian terms, underlying unity is a paradigm for paradigms. We need a conception of science which represents problematic assumptions concerning the physical comprehensibility and knowability of the universe in the form of a hierarchy, these assumptions becoming less and less substantial and more and more such that their truth is required for science, or the pursuit of knowledge, to be possible at all, as one goes up the hierarchy. This hierarchical conception of science has important Kuhnian features, but also differs dramatically from the view Kuhn expounds in his The Structure of Scientific Revolutions. In this paper, I compare and contrast these two views in a much more detailed way than has been done hitherto. I show how the hierarchical view can be construed to emerge from Kuhn’s view as it is modified to overcome objections. I argue that the hierarchical conception of science is to be preferred to Kuhn’s view.     

What is interdisciplinary communication? Reflections on the very idea of disciplinary integration

In this paper I attempt to answer the question: What is interdisciplinary communication? I attempt to answer this question, rather than what some might consider the ontologically prior question—what is interdisciplinarity (ID)?—for two reasons: (1) there is no generally agreed-upon definition of ID; and (2) one’s views regarding interdisciplinary communication have a normative relationship with one’s other views of ID, including one’s views of its very essence. I support these claims with reference to the growing literature on ID, which has a marked tendency to favor the idea that interdisciplinary communication entails some kind of ‘integration’. The literature on ID does not yet include very many philosophers, but we have something valuable to offer in addressing the question of interdisciplinary communication. Playing somewhat fast-and-loose with traditional categories of the subdisciplines of philosophy, I group some philosophers—mostly from the philosophy of science, social–political philosophy, and moral theory—and some non-philosophers together to provide three different, but related, answers to the question of interdisciplinary communication. The groups are as follows: (1) Habermas–Klein, (2) Kuhn–MacIntyre, and (3) Bataille–Lyotard. These groups can also be thought of in terms of the types of answers they give to the question of interdisciplinary communication, especially in terms of the following key words (where the numbers correspond to the groups from the previous sentence): (1) consensus, (2) incommensurability, and (3) invention.     

The Structure’s Legacy: Not from Philosophy to Description

In the paper I consider how empirical material, from either history or sociology, features in Kuhn’s account of science in The Structure of Scientific Revolutions and argue that the study of scientific practice did not offer him data to be used as evidence for defending hypotheses but rather cultivated a sensitivity for detail and difference which helped him undermine an idealized conception of science. Recent attempts in the science studies literature, appealing to Wittgenstein’s philosophy, have aimed at reducing philosophy to multifaceted empirical research in relation to science. I discuss how this turn which is at odds with Wittgenstein’s philosophy, cannot be a continuation of Kuhn’s project which bears similarities to Wittgenstein’s.     

Putting Thoughts to Work: Concepts,Systematicity, and Stimulus‐Independence*

I argue that we can reconcile two seemingly incompatible traditions for thinking about concepts. On the one hand, many cognitive scientists assume that the systematic redeployment of representational abilities suffices for having concepts. On the other hand, a long philosophical tradition maintains that language is necessary for genuinely conceptual thought. I argue that on a theoretically useful and empirically plausible concept of ‘concept’, it is necessary and sufficient for conceptual thought that a thinker be able to entertain many of the potential thoughts produced by recombining her representational abilities apart from a direct confrontation with the states of affairs being represented. Such representational abilities support a cognitive engagement with the world that is flexible, abstract, and active.     

The Proper Structure of the Intellectual Virtues

If we adopt a virtue approach to epistemology, what form should the intellectual virtues take? In this paper, I argue that the proper structure of the intellectual virtues should be one that follows the tradition of internalism in epistemology. I begin by giving a general characterization of virtue epistemology and then define internalism within that framework. Arguing for internalism, I first consider the thought experiment of the new evil demon and show how externalist accounts of intellectual virtue, though constructed to accommodate our intuitions in such cases, cannot fully do so. I further argue that only adopting an internalist structure of the virtues will provide intellectual virtues that appropriately mirror the structure of the classical moral virtues. Finally, I argue that only an internalist structure of the virtues can explain why the intellectual virtues are valuable in themselves.     

A Critical Assessment of the Programmes of Producing ‘Islamic Science’ and ‘Islamisation of Science/Knowledge’

In the present article, working from within the framework of critical rationalism and focusing mostly on the views developed by some Iranian writers, I argue that the programmes of producing ‘Islamic Science’ (cIS) and ‘Islamisation of Science/Knowledge’ (IoK) are doomed to failure. I develop my arguments in three parts. I start by explaining that the advocates of the programmes of producing cIS or IoK subscribe to mistaken images of science that are shaped by either a positivist or outmoded culturalist/interpretivist theories of science. I shall then focus on the similarities and differences of ‘science’ and ‘technology’, arguing that despite close interconnection between the two it is of utmost importance, for analytical purposes, to keep these two socially constructed entities apart. Drawing on the above distinction, I argue that while creating ‘Islamic’ or ‘indigenous’ sciences is impossible, constructing ‘Islamic’ or ‘indigenous’ technologies is, in principle, feasible. Lastly, I turn to some of the more recent works on creating/constructing cIS and/or IoK. I shall try to show that none of the arguments introduced by the advocates of the projects of cIS/IoK is tenable.     

A Gadamerian Critique of Kuhn’s Linguistic Turn: Incommensurability Revisited

In this article, I discuss Gadamer’s hermeneutic account of understanding as an alternative to Kuhn’s incommensurability thesis. After a brief account of Kuhn’s aesthetic account and arguments against it, I argue that the linguistic account faces a paradox that results from Kuhn’s objectivist account of understanding, and his lack of historical reflexivity. The statement ‘Languages are incommensurable’ is not a unique view of language, and is thus subject to contest by incommensurable readings. Resolving the paradox requires an account of incommensurability that is self‐referentially consistent, open‐ended, and historically reflexive whereby we recognize that our very interest in incommensurability is historically conditioned. By meeting these conditions, Gadamer’s account of historical understanding offers a middle ground between two extremes: on the one side is the claim that understanding involves becoming a native of an incommensurable language, and on the other side is the rejection of the prospect of understanding a contextually removed language altogether. Gadamer is discussed as a mediator between Kuhn’s epistemic and historical projects, and thus paves the way for a new hermeneutics of science. The notions of traditional horizon, historically effected consciousness, the universality of interpretation, alienation, dialogical openness, and the fusion of horizons are also discussed.     

The Freedom of Thought: Patočka on Descartes and Husserl

Pato?ka highlights the central role of Cartesianism in our tradition of thinking. Yet, today, brain scientists often claim to have overcome Cartesian dualism. In this paper, I argue that the Cartesian conceptions of human nature and sensory perception remain presuppositions of brain science, where perception is largely equated with thinking. Equating perception and thinking means that thinking is a determined process, which leads to an erosion of critique. Critique, and the freedom of thought it entails, is essential to Descartes, Husserl and Pato?ka. I examine the differences, as well as the relationship, between Descartes method of doubt, Husserl’s phenomenological epochē and Pato?ka’s universalization of the epochē. I also show how Descartes’, Husserl’s and Pato?ka’s way into critique present different ways to understand self, things and the world. In conclusion, I suggest that Pato?ka presents a promising way to critique mechanistic understandings of thinking by rethinking both subject and object.     

Indiscernible universals

Universals have traditionally thought to obey the identity of indiscernibles, that is, it has traditionally been thought that there can be no perfectly similar universals. But at least in the conception of universals as immanent, there is nothing that rules out there being indiscernible universals. In this paper, I shall argue that there is useful work indiscernible universals can do, and so there might be reason to postulate indiscernible universals. In particular, I shall argue that postulating indiscernible universals can allow a theory of universals to identify particulars with bundles of universals, and that postulating indiscernible universals can allow a theory of universals to develop an account of the resemblance of quantitative universals that avoids the objections that Armstrong’s account faces. Finally, I shall respond to some objections and I shall undermine the criterion of distinction between particulars and universals that says that the distinction between particulars and universals lies in that while there can be indiscernible particulars, there cannot be indiscernible universals.
