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 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

Philip Kitcher’s account of scientific realism in 'The Advancement of Science' (AS) differs from his account in 'Science, Truth and Democracy' (STD). We demonstrate that (1) contrary to appearance, Kitcher in AS proposes a so-called Kantian realism that is accompanied not by a correspondence theory, but by a hybrid conception of truth. (2) Also, we point out that Kitcher does not pertain to the “promiscuous realism” proposed in STD stringently, but falls back on his Kantian realism of AS at points. Here, we question Kitcher’s claim that his promiscuous-realist conception stems initially from commonsensical be-liefs.

In two recent papers in Studies in History and Philosophy of Science Howard Sankey has argued that there is an intimate relationship between Pyrrhonian skepticism and recent approaches to epistemic relativism.Though the general argument and idea of Sankey’s papers is very much appreciated, it is argued that the epistemic relativist’s recourse to the skeptical strategy outlined by the Pyrrhonian is not a good one. This diagnosis gives rise to an objection against the epistemic relativist who argues on the basis of the skeptical strategy that differs from Sankey’s naturalistic response. Furthermore, it can be shown that what is really at stake between epistemic relativism and epistemic absolutism is the question of which criteria there are for variation of epistemic norms and epistemic systems.

In this paper, I show that there are important but hitherto unnoticed similarities between key figures of the Vienna Circle and early defenders of sociology of knowledge. The similarities regard their stance on potential implications of the study of science for political and societal issues. I argue that notably Otto Neurath and Karl Mannheim are concerned with proposing a genuine political philosophy of science that is remarkably different from today’s emerging interest in the relation between science and society in philosophy of science
