Karl Popper is famous for having proposed that science advances by a process of conjecture and refutation. He is also famous for defending the open society against what he saw as its arch enemies – Plato and Marx. Popper’s contributions to thought are of profound importance, but they are not the last word on the subject. They need to be improved. My concern in this book is to spell out what is of greatest importance in Popper’s work, what its failings (...) are, how it needs to be improved to overcome these failings, and what implications emerge as a result. The book consists of a collection of essays which dramatically develop Karl Popper’s views about natural and social science, and how we should go about trying to solve social problems. Criticism of Popper’s falsificationist philosophy of natural science leads to a conception of science that I call aim-oriented empiricism. This makes explicit metaphysical theses concerning the comprehensibility and knowability of the universe that are an implicit part of scientific knowledge – implicit in the way science excludes all theories that are not explanatory, even those that are more successful empirically than accepted theories. Aim-oriented empiricism has major implications, not just for the academic discipline of philosophy of science, but for science itself. Popper generalized his philosophy of science of falsificationism to arrive at a new conception of rationality – critical rationalism – the key methodological idea of Popper’s profound critical exploration of political and social issues in his The Open Society and Its Enemies, and The Poverty of Historicism. This path of Popper, from scientific method to rationality and social and political issues is followed here, but the starting point is aim-oriented empiricism rather than falsificationism. Aim-oriented empiricism is generalized to form a conception of rationality I call aim-oriented rationalism. This has far-reaching implications for political and social issues, for the nature of social inquiry and the humanities, and indeed for academic inquiry as a whole. The strategies for tackling social problems that arise from aim-oriented rationalism improve on Popper’s recommended strategies of piecemeal social engineering and critical rationalism, associated with Popper’s conception of the open society. This book thus sets out to develop Popper’s philosophy in new and fruitful directions. The theme of the book, in short, is to discover what can be learned from scientific progress about how to achieve social progress towards a better world. (shrink)

I compare the epistemic culture of Wikipedia with the epistemic culture of science, with special attention to the culture of collaborative research in science. The two cultures differ markedly with respect to (1) the knowledge produced, (2) who produces the knowledge, and (3) the processes by which knowledge is produced. Wikipedia has created a community of inquirers that are governed by norms very different from those that govern scientists. Those who contribute to Wikipedia do not ground their claims on their (...) reputations as knowers, for they stand to lose nothing if and when their contributions are found to be misleading or false. And the immediacy of the medium encourages gossip and jokes. Hence, though we have some reason to believe that an invisible hand aids scientists in realizing their epistemic goals, we cannot ground our confidence in what is reported on Wikipedia on the fact that an invisible hand ensures quality. Nor is the information on Wikipedia aptly justified in a manner similar to the way testimony can be justified. (shrink)

In August 2002, three Indian computer scientists published a paper, ‘PRIMES is in P’, online. It presents a ‘deterministic algorithm’ which determines in ‘polynomial time’ if a given number is a prime number. The story was quickly picked up by the general press, and by this means spread through the scientific community of complexity theorists, where it was hailed as a major theoretical breakthrough. This is although scientists regarded the media reports as vulgar popularizations. When the paper was published in (...) a peer-reviewed journal only two years later, the three scientists had already received wide recognition for their accomplishment. Current sociological theory challenges the ability to clearly distinguish on independent epistemic grounds between distorted and non-distorted scientific knowledge. It views the demarcation lines between such forms of presentation as contextual and unstable. In my paper, I challenge this view. By systematically surveying the popular press coverage of the ‘PRIMES is in P’ affair, I argue--against the prevailing new orthodoxy--that distorted simplifications of scientific knowledge are distinguishable from non-distorted simplifications on independent epistemic grounds. I argue that in the ‘PRIMES is in P’ affair, the three scientists could ride on the wave of the general press-distorted coverage of their algorithm, while counting on their colleagues’ ability to distinguish genuine accounts from distorted ones. Thus, their scientific reputation was unharmed. This suggests that the possibility of the existence of independent epistemic standards must be incorporated into the new SSK model of popularization.

Is knowledge in the natural sciences discovered or constructed? For objectivists, scientific knowledge is discovered through investigations into a mind-independent, natural world. For constructivists, such knowledge is produced through negotiations among members of a professional guild. I examine the clash between the two positions and propose that scientific knowledge is the concurrent outcome from investigations into a natural world and from consensus reached through negotiations of a professional guild. Specifically, I introduce the general methodological notion, instituting science, which incorporates both (...) the discovery and the construction processes in the generation of scientific knowledge. To that end, I use a case study from the biomedical sciences to illustrate the notion. I conclude with a discussion of how this methodological notion helps to address the debate between objectivists and constructivists over the generation of scientific knowledge, and of how it compares with others who have also attempted to address the debate.

REVIEW (1): "Jeff Kochan’s book offers both an original reading of Martin Heidegger’s early writings on science and a powerful defense of the sociology of scientific knowledge (SSK) research program. Science as Social Existence weaves together a compelling argument for the thesis that SSK and Heidegger’s existential phenomenology should be thought of as mutually supporting research programs." (Julian Kiverstein, in Isis) ---- REVIEW (2): "I cannot in the space of this review do justice to the richness and range of Kochan's (...) discussion [...]. There is a great deal in this foundational portion of Kochan's discussion that I find tremendously interesting and engaging [...]." (David R. Cerbone, in Studies in History and Philosophy of Science) ---- REVIEW (3): "Science as Social Existence will be of interest not only to Heidegger scholars but to anyone engaged in science and technology studies. [...] This is an informative and original book. Kochan should be praised for his clear, pleasant-to-read prose." (Michael Butler, in CHOICE). (shrink)

Das Thema dieses Bandes ist die Frage, ob die Wissenschaftstheorie eine normative Disziplin ist. Zunächst überrascht die Frage, denn für viele Wissenschaftstheoretiker ist die Antwort ein klares „Ja“; sie halten es für einen Allgemeinplatz, dass die Wissenschaftstheorie ein normatives Unternehmen ist. Bei genauerem Hinsehen stellt sich jedoch heraus, dass die Frage unterschiedliche Interpretationen zulässt, die einzeln diskutiert werden müssen. Dies geschieht im ersten Abschnitt. Im zweiten Abschnitt suchen wir nach möglichen Erklärungen dafür, warum die Wissenschaftstheorie bisher bei dem Projekt, eine (...) allseits akzeptable Methodologie wissenschaftlichen Schließens zu formulieren und zu begründen, so wenig Erfolg hatte. Eine mögliche Erklärung für den ausbleibenden Erfolg ist der Partikularismus, wonach Methoden keine allgemeine, sondern nur eine lokale, bereichsabhängige Gültigkeit haben. Im dritten Abschnitt wollen wir an Hand des Bayesianismus zeigen, dass die Methodologie doch nicht so schlecht da steht, wie es zunächst den Anschein hat. Der Bayesianismus ist für viele Wissenschaftstheoretiker der aussichtsreichste Kandidat für eine allgemeine Theorie induktiven Räsonierens. Wir besprechen seine Vorzüge, stellen aber auch dar, welche Konzessionen er an den Partikularismus machen muss. (shrink)

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

Helen Longino argues that the way to ensure scientific knowledge is objective is to have a diversity of scientific investigators. This is the best example of recent feminist arguments which hold that the real value of diversity is epistemic, and not political, but it only partly succeeds. In the end, Longino's objectivity amounts to intersubjective agreement about contextually based standards, and while her account gives us a good reason for wanting diversity in our scientific communities, this reason turns out to (...) be political.

There has been a sharp rise in private funding of medical research, especially in relation to patentable products. Several serious problems with this are described. A solution involving the elimination of patents and public funding administered through extended national health care systems is proposed.

“The day the Enlightenment went out”, is how Gary Wills described the re-election of President George W. Bush in an op-ed column in the New York Times (November 4, 2004). Reflecting upon the conservative religious vote that put Bush back in the White House, Wills wondered if there was any connection between the fact that many more Americans believe in the Virgin Birth than in Darwin’s theory of evolution and that 75 percent of Bush supporters actually believed—without an iota of (...) credible evidence— that Iraq was directly responsible for the terrorist attack on 9/11. Wills asks if a people that have lost respect for evidence and critical reasoning can still be called an enlightened nation. “Belief that does not require proof or evidence” is how the Webster New World Dictionary defines the word “faith”. It also defines “faith” as “faith in God”. The American elections, then, turned out to be a massive faith-based initiative in both these senses of the word. Belief and policies backed not by evidence, but by religious values wedded to an aggressive nationalism are driving American politics. In this America is not alone. India, the subject matter of much of what follows, has had its own brush with faith-driven politics in which an aggressive Hindu nationalism came to color public policies, including science education.1 The question is: how do secular democracies like the United States and India (the world’s first and the world’s largest democracies, respectively), manage to square off their official commitment to enlightened values of openness and religion–state separation with the realities of faith-based politics? How do matters of fact—that is, questions that in principle can be decided by empirical evidence—end up getting decided on the basis of religious faith. This alchemy of turning secular matters of fact into religiouscivilizational matters holds the key to understanding the democratic-populist route to religious fundamentalism.. (shrink)

The sociology of science seeks to theorize the social conditioning of science. This theorizing seems to undermine the validity of scientific knowledge and lead to relativism. Bourdieu and Latour both attempt to develop a sociology of science that overcomes relativism but stipulate opposite conditions for the production of scientific truths: while Bourdieu emphasizes autonomy, Latour emphasizes associations. This is because they work with oppositional epistemological and ontological assumptions. In both theories, the notion of truth lacks an independent definition; it is (...) derived from the theorist’s position on rationalism and defined with reference to how it is produced. This interdependence creates a different problem in each case. Bourdieu’s assertion that truths produced in relatively autonomous scientific fields are “trans-historical” remains an epistemological assertion. Latour’s argument that truths are produced through associations fails to capture the different resources, distinctions and boundarie.. (shrink)

It's sometimes useful to start with a quiz, even if it seems irrelevant to the issues at hand. Suppose you have to organize a tennis tournament with, say, 1025 players. Match winners will go on to the next round while losers bow out until all have been eliminated except, of course, the final champion. Your problem is this: How many matches must you book for this tournament?

The present article offers an introductory vision to the political philosophy of science. The political philosophy of science is a new field of study where the philosophy of science and political philosophy converge. We will see the main contents of this field. We will also note that it depends on the construction of a model of rationality where science and politics can meet each other. Finally, the article tries to outline such a model of rationality. In order to do so, (...) we will review the relationship between Karl Popper’s scientific and political philosophy. I suggest to read Popper’s critical rationalism in terms of a kind of prudential rationality. (shrink)

Darwin’s theory of evolution by natural selection is central to modern biology, but is resisted by many people. This paper discusses the major psychological obstacles to accepting Darwin’s theory. Cognitive obstacles to adopting evolution by natural selection include conceptual difficulties, methodological issues, and coherence problems that derive from the intuitiveness of alternative theories. The main emotional obstacles to accepting evolution are its apparent conflict with valued beliefs about God, souls, and morality. We draw on the philosophy of science and on (...) a psychological theory of cognitive and emotional belief revision to make suggestions about what can be done to improve acceptance of Darwinian ideas.

This article highlights that in our rush to call for the democratization of science and expertise we must not forget to speak to what type of democratization we are calling for. In short, not all participatory forms are the same. In developing this argument, I examine one such form that has yet to receive much attention from science and technology studies scholars: the agricultural field day. In examining the field day, we find that its orientation—that is, toward either the conventional (...) or sustainable model of agriculture—shapes significantly its democratic approach to knowledge coproduction. To help inform how we understand conventional and sustainable field days, I turned to two conceptual frameworks of participation: namely, that of Wynne and Funtowicz and Ravetz. In doing this, we find that conventional field days mirror closely that form of public participation detailed by Funtowicz and Ravetz, while sustainable field days reflect that conceptualized by Wynne.

The Science Wars have not involved any violence, nor even threats of violence. Thus the label “wars” for this series of discussions, mostly one-sided and mostly located within the academy, is something of an overblown metaphor. Nonetheless, I will suggest that there are some respects in which the metaphor is appropriate. The Science Wars involve territory, albeit a metaphorical kind of territory. They inspire work that can be best interpreted as ideological, a result of disciplinary interests. Moreover, fellow participants in (...) the wars and others reward that ideological work.My goal in this is to display efforts to maintain a discipline's epistemic authority, the recognition that members of that discipline have legitimate claims to knowledge on a subject. The central section of the paper takes the form of a discussion of one recent contribution to the Science Wars, James Robert Brown's Who Rules in Science? My argument is at least somewhat generalizable beyond this book, and it therefore points to interesting phenomena related to epistemic authority. (shrink)

These reflections range over some distinctive features of the journal Science & Education, they acknowledge in a limited way the many individuals who over the past 25 years have contributed to the success and reputation of the journal, they chart the beginnings of the journal, and they dwell on a few central concerns—clear writing and the contribution of HPS to teacher education. The reflections also revisit the much-debated and written-upon philosophical and pedagogical arguments occasioned by the rise and possible demise (...) of constructivism in science education.

In this paper, it is argued that although data mining (DM) is being touted as a solution to many business problems and is basking in the glory of electronic business environments of today, as practiced currently, it reflects a preoccupation with short-run commercial applications and a neglect of the underlying theoretical issues. Although an argument can be made that theoretical precedence is not a necessary prerequisite for practical application or for commercial success, it can also be argued that an exclusive (...) reliance on data-driven and exploratory components of pattern recognition without a corresponding attention to the causal schemas underlying patterns is destined to limit the potential for DM to evolve into a long-term solution to business problems or into an intellectual discipline in its own right. This paper presents an overview of key features and assumptions in DM and examines some of the key practical, philosophical, and foundational issues in DM. (shrink)

Financial conflicts of interest in medical research foster deviations from research standards and evidentially lead to the suppression of research findings that are at odds with commercial interests of pharmaceutical companies. Questionable research practices prevent data from being created, made available, or given suitable recognition. They run counter to codified principles of responsible conduct of research, such as honesty, openness or respect for the law. Resulting in ignorance, misrepresentation and suspension of scientific self-correction, suppression of medical evidence in its various (...) forms is both a threat to the epistemic and the moral integrity of medical science. This paper discusses an example of the suppression of medical evidence in recent influenza research and develops a conceptual framework for the description and assessment of questionable research practices applied in research and publication processes to suppress evidence.

I argue that, in analysing the structure and development of moral traditions, MacIntyre relies primarily on Kuhn's model of scientific tradition, rather than 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.

Sergio Sismondo's “Boundary Work and the Science Wars” nicely exemplifies a hotly debated central issue. One side, let me call them the rationalists, tries to explain episodes in the history of science in terms of reason. They claim that scientists, past and present, believe what they do because of the evidence that they have at the time. The other side, following Sismondo, let me call them STSers , claim that social and other non-cognitive factors are the frequent causes of belief. (...) This disagreement naturally leads to a meta-level debate. Rationalists, such as myself, try to give reasons for believing the STSers are wrong-headed in their approach. And Sismondo replies with the claim that whether I realize it or not I am really doing boundary work – an explanation of my activity in terms of social factors. (shrink)

This paper argues that a naturalized epistemology of the kind presented by W.V. Quine preserves everything worthwhile in traditional epistemology. Arguments against Quinean naturalism by such writers as Laurence BonJour, Jaegwon Kim, Richard Rorty, Barry Stroud, and Donald Davidson are criticized. Contrary to what is sometimes assumed, Quinean naturalism does not reject a priori justification. The important point is that epistemology is contained in science. There is no ‘first philosophy’, and, in particular, epistemology is not a normative discipline. Nevertheless, there (...) is a sense in which Quinean naturalism provides an answer to Cartesian scepticism. (shrink)

Diese Arbeit untersucht die Frage, welche möglichen Auslöser für emotional bedingte Voreingenommenheit es auf Seiten der Kritiker des heutigen philosophischen Naturalismus gibt. Sie findet diese zum einen in bestimmten Ergebnissen einzelner wissenschaftlicher Disziplinen, den sogenannten ›Kränkungen‹, die fälschlicherweise dem philosophischen Naturalismus angelastet werden, und zum anderen in den programmatischen Voraussetzungen des philosophischen Naturalismus, den ›naturalistischen Zumutungen‹. Nach einer kurzen Darstellung des naturalistischen Programms werden diese beiden Gruppen exemplifiziert, voneinander abgegrenzt und zwei Ansätze zur Klärung von Missverständnissen der naturalistischen Position vorgeschlagen.
