Thomas S. Kuhns Buch,,Die Struktur wissenschaftlicher Revolutionen" zählt zweifelsohne zu einem der einflussreichsten Werke innerhalb der Wissenschaftstheorie des vergangenen Jahrhunderts. Mit seinen wissenschaftshistorisch gestützten Überlegungen zu revolutionären Paradigmenwechseln fordert er ein naives Bild des kumulativen Fortschritts der Wissenschaften heraus. Das Buch ist damit einer der Ausgangspunkte der sogenannten,historischen Wende' in der Wissenschaftsphilosophie. Und noch heute provoziert die Verwendung der Begriffe,,Paradigma",,,Normalwissenschaft",,,Krisenforschung",,,Anomalie" oder,,Inkommensurabilität" teils erbitterte Debatten in der Wissenschaftsphilosophie. Neben der außerordentlichen Relevanz, die Kuhns Buch für akademische Debatten in der Philosophie und der Wissenschaftstheorie hatte, ist darüber hinaus aber auch die ungemeine Popularität des Buches bemerkenswert: Fast 1,5 Million Exemplare der englischen Ausgabe wurden verkauft,,The Times Literary Supplement' zählt das Buch zu den 100 einflussreichsten Büchern nach dem Zweiten Weltkrieg, der ehemalige Vize-Präsident und Friedensnobelpreisträger Al Gore nennt das Buch als eines seiner Lieblingsbücher und in vielen Einführungsvorlesungen zu methodischen Grundlagen von Spezialdisziplinen wird das Buch erwähnt. Der Band versammelt Beiträge der national und international führenden Experten zu Kuhns Klassiker und ermöglicht so die kapitelweise Erschließung des Originaltextes.

Universitäten weisen als institutioneller Inbegriff von Wissenschaft eine immense Fächervielfalt auf. Doch was hält diese Vielfalt der Wissenschaften zusammen, und was sind deren jeweiligen Besonderheiten? Ist es überhaupt sinnvoll, solch unterschiedliche Forschungsbereiche wie zum Beispiel die Koptologie und die Materialphysik nach ähnlichen Standards zu bewerten und zu vergleichen? Ist solch eine Vielfalt notwendig für den Erkenntnisfortschritt oder eher ein Hemmnis, das es zu überwinden gilt? Wie hängen die Theorien, Methoden und Gegenstandsbereiche der verschiedenen Disziplinen miteinander zusammen – haben die Disziplinen einen je eigenen Zugriff auf verschiedene Aspekte der Wirklichkeit, oder lassen sich die Theorien und Erklärungen einiger Disziplinen auf die anderer zurückführen? Fragen dieser Art werden in diesem Buch aus der Perspektive verschiedener Disziplinen betrachtet.

This article focuses on the role considerations about the history of science play in philosophical debates about disagreement in science. First the article shortly reflects on the relationship between history and philosophy of science. Second, the article focuses on figuring out the impact of Kuhn’s and Feyerabend’s much discussed claims about incommensurability on the question of disagreement. It is shown that incommensurability introduces a plethora of potential issues of disagreement in science. The article closes by some remarks about using examples from the history of science in the debate about scientific realism: the same cases of disagreement in the history of science can be interpreted in a realist or anti-realist way.

In this article we focus on Sally Haslanger’s theoretical project of distinguishing between different ways to understand social constructionist theses in general. The goal of this article is to better understand Haslanger’s distinction between different forms of social constructionism. In trying to get a better grasp of Haslanger’s distinctions we will encounter some difficulties that will hinder us getting a coherent picture of these distinctions. For some of these difficulties we will present some possible solutions but, in the end, we will ask for further commentary from Haslanger herself to improve on our understanding of her distinction between different forms of social constructionism.

This chapter discusses whether the appropriation of Kuhnian thoughts by the so-called Strong Programme in the sociology of scientific knowledge is appropriate. In order to answer the question of appropriate appropriation, Kuhn’s and the Strong Programme’s stances on two “isms” are compared: relativism and naturalism. It is shown that the Strong Programme clearly goes beyond Kuhn and breaks more radically with philosophical tradition. Nevertheless, there are also philosophical continuities and similarities.

In this paper we show that Audi’s fallibilist foundationalism is beset by three unclarities. First, there is a conceptual unclarity in that Audi leaves open if and how to distinguish clearly between the concepts of fallibility and defeasibility. Second, there is a general unclarity: it is not always clear which fallibility/defeasibility-theses Audi accepts or denies. Finally, there is an unclarity of self-application because Audi does not specify his own claim that fallibilist foundationalism is an inductivist, and therefore itself fallible, thesis. The critical part of our paper is supplemented by a constructive part, in which we present a space of possible distinctions between different fallibility and defeasibility theses. These distinctions can be used by Audi as a toolkit to improve the clarity of fallibilist foundationalism and thus provide means to strengthen his position.

Whereas there is much discussion about Thomas Kuhn’s notion of methodological incommensurability and many have seen his ideas as an attempt to allow for rational disagreement in science, so far no serious analysis of how exactly Kuhn aims to account for rational disagreement has been proposed. This paper provides the first in-depth analysis of Kuhn’s account of rational disagreement in science—an account that can be seen as the most prominent attempt to allow for rational disagreement in science. Three things will be shown: First, we find not one, but two accounts of rational disagreements in science in Kuhn’s writings: one stemming from methodological incommensurability and one stemming from Kuhn-underdetermination, which are not only fundamentally different—the first purports to explain how disagreeing scientists can nevertheless be rational, while the second attempts to show how rational scientists can nevertheless disagree—but appear to be incompatible with each other. Second, I will assess both accounts. Kuhn’s account from methodological incommensurability is not convincing since it cannot explain rational disagreement in science. Whereas, on the other hand, Kuhn’s account from Kuhn-underdetermination allows for rational disagreement, his argument why we should accept it is not convincing. Third, I present a tentative sketch of an alternative to Kuhn’s account that emphasizes the fallibility of epistemic justification in order to show that Kuhn’s argument founders. In sum, the paper shows that focusing not on the muchly debated consequences of methodological incommensurability, but on Kuhn’s treatment of rational disagreement gives new insight into the adequate interpretation of his thought as well as the cogency of his ideas.

In this paper, we will discuss Peter van Inwagen’s contribution to the epistemological debate about revealed peer disagreement. Roughly, this debate focuses on situations in which at least two participants disagree on a certain proposition based on the same evidence. This leads to the problem of how one should react rationally when peer disagreement is revealed. Van Inwagen, as we will show, discusses four possible reactions, all of which he rejects as unsatisfying. Our proposal will be to point to hidden assumptions in van Inwagen’s reasoning and ask whether he is willing to reject at least one of these to get rid of the problem. In short, our thesis amounts to the following: Of the two epistemological claims, which we call “Weak” and “Full-blown Fallibilism”, van Inwagen cannot simultaneously accept the first and reject the latter, while this is what he seems to suggest. Revealing this potential dilemma for van Inwagen’s position will lead to a more detailed discussion of how “rationality”, “truth”, “evidence” and “justification” interrelate and how a closer look at their relation might help solving the puzzle of revealed peer disagreement.

In this paper I will introduce a practical explication for the notion of expertise. At first, I motivate this attempt by taking a look on recent debates which display great disagreement about whether and how to define expertise in the first place. After that I will introduce the methodology of practical explications in the spirit of Edward Craig’s Knowledge and the state of nature along with some conditions of adequacy taken from ordinary and scientific language. This eventually culminates in the respective explication of expertise according to which this term essentially refers to a certain kind of service-relation. This is why expertise should be considered as a predominantly social kind. This article will end up with a discussion of advantages and prima facie plausible objections against my account of expertise.

In a paper published in this journal Martin Hinton aims to show that the struggle between Moti Mizrahi and me about whether arguments from expert opinion are weak arguments rests on misunderstandings (Hinton 2015). Let me emphasize that I generally appreciate Hinton’s intention to settle the dispute between Mizrahi and myself in this way. 1 Furthermore, I also agree with Hinton’s conclusion that if Mizrahi is interpreted in the way Hinton does, then Mizrahi’s “claim becomes far less controversial, but also rather uninteresting” (Hinton 2015, 551)—to refer to the title of my former paper: just spilling out the water wouldn’t be worth a paper in Informal Logic. 2 Let me therefore focus in this reply on the points where Hinton directly attacks my treatment of Mizrahi and also what Hinton takes to be my account of expertise. I will discuss the following criticism of Hinton: (1) that, at points, my attack on Mizrahi is unfair due to my misunderstanding of his intentions, (2) that the notion of expertise I use is self-contradictory/inconsistent, (3) that the argument for my view is circular, (4) that one of my examples—the example from soccer—is mistaken. In rebutting this criticism, I aim to clarify the background of my former paper in this journal.

This paper discusses Sosa’s via media between existential relativism and absolutism. We discuss three implications of Sosa’s account which require some further clarification. First, we distinguish three alternative readings of Sosa’s account – the indexicalist, the homonymist and the (proper) relativist reading – and argue that they differ with respect to two crucial points: (a) they lead to different analyses of the lack of disagreement in existential discourse, and (b) they differ with respect to the question of whether conceptual schemes pick out different senses of “exist” or whether they pick out different entities to exist. Second, we ask Sosa to answer on four problematic implications of his final position: (a) Sosa appears to change the topic from ontology to semantics without solving the ontological issue. (b) It is puzzling why Sosa finally accepts the initially implausible explosion of reality. (c) Sosa is forced to accept that disputants really disagree in existential disputes (although faultlessly). (d) We offer an even simpler alternative option to reconcile the realist and the relativist intuitions by clarifying what is meant by “conceptual relativism”, without arguing for existential relativity at all. Third, we argue that Sosa’s argumentative reliance on an appropriate development of conceptual schemes drives him not only to a position of pure conceptual absolutism, but even to a more traditional form of ontological absolutism according to which nature itself manages to cut the cookies. In contrast to his apparent intention, this discharges Sosa’s via media from any relativist intuition.

In this paper I argue that a moderate form of epistemic relativism that is inspired by the work of Thomas Kuhn fails. First of all, it is shown that there is evidence to the effect that Kuhn already in his 'The Structure of Scientific Revolutions' proposes moderate relativism. Second, it is argued that moderate relativism is confronted with a severe dilemma that follows from Kuhn’s own argument for his relativistic conclusion. By focusing on the work of moderate relativists like Bernd Schofer and Gerald Doppelt this dilemma as well as the ultimate failure of Kuhn’s moderate relativism are exhibited.

The paper explores the defence by the early sociologist of science Ludwik Fleck against the charge of relativism. It is shown that there are crucial and hitherto unnoticed similarities between Fleck’s strategy and the attempt by his contemporary Karl Mannheim to distinguish between an incoherent relativism and a consistent relationism. Both authors seek to revise epistemology fundamentally by reinterpreting the concept of objectivity in two ways: as inner- and inter-style objectivity. The argument for the latter concept shows the genuine political background and intent of Fleck’s sociology of science and its ambition to relieve the cultural struggles of his time
