This paper suggests a new way of analysing testimony. The starting point of the analysis is ‘epistemological communitarianism’. This is the view that communities, rather than individuals, are the primary bearers of knowledge. The new perspective is developed through a discussion of four issues: the scope of testimony; the role of inferences in the reception and evaluation of testimony; the possibility of a global justification of testimony; and the question of whether testimony is a generative source of knowledge or a mere means of transmission of already existing knowledge. The last-mentioned issue is given special prominence. It is argued that testimony is a generative source of knowledge.Author Keywords: Testimony; Communitarianism; Epistemology; Trust; Sociology of knowledge

Psychologists and philosophers have assumed that psychological knowledge is knowledge about, and held by, the individual mind. _Psychological Knowledge_ challenges these views. It argues that bodies of psychological knowledge are social institutions like money or the monarchy, and that mental states are social artefacts like coins or crowns. Martin Kusch takes on arguments of alternative proposals, shows what is wrong with them, and demonstrates how his own social-philosophical approach constitutes an advance. We see that exists a substantial natural amount of philosophical theorising, a body of work that tries to determine the nature and structure of folk psychology. Examining the workings of constuctivism, _Psychological Knowledge_ is an invaluable introduction to the history of psychology and the recent philosophy of mind.

No other recent book in Anglophone philosophy has attracted as much criticism and has found so few friends as Saul Kripke's "Wittgenstein on Rules and Private Language". Amongst its critics, one finds the very top of the philosophical profession. Yet, it is rightly counted amongst the books that students of philosophy, at least in the Anglo-American world, have to read at some point in their education. Enormously influential, it has given rise to debates that strike at the very heart of contemporary philosophy of mind and language. In this major new interpretation, Martin Kusch defends Kripke's account against the numerous weighty objections that have been put forward over the past twenty years and argues that none of them is decisive. He shows that many critiques are based on misunderstandings of Kripke's reasoning; that many attacks can be blocked by refining and developing Kripke's position; and that many alternative proposals turn out either to be unworkable or to be disguised variants of the view they are meant to replace. Kusch argues that the apparent simplicity of Kripke's text is deceptive and that a fresh reading gives Kripke's overall argument a new strength

This chapter gives substance to the idea of a ‘communitarian value-driven epistemology’ by developing and combining ideas from Edward Craig's and Bernard Williams' ‘epistemic genealogy’ and Barry Barnes' and Steven Shapin's ‘sociology of knowledge’. In order to make transparent how this project might slot into more familiar, or more mainstream, projects, the paper maintains throughout a critical dialogue with Jon Kvanvig's position. The chapter is structured around an attempt to defend Craig's position against Kvanvig's criticisms: by treating the institution of testimony as a collective good underwritten by the intrinsic and interrelated values of accuracy and sincerity; by rendering protoknowledge attributions as ascriptions of honour; and by allowing attributions of protoknowledge to be intertwined with attributions of freedom. The view that emerges is that the core of our knowledge practices comprises institutions of testimony, and that these practices are a collective good.

The paper begins with a detailed reconstruction of the development of Ian Hacking’s theory of scientific ‘styles of reasoning’, paying particular attention to Alistair Crombie’s influence, and suggesting that Hacking’s theory deserves to come under the title ‘historical epistemology’. Subsequently, the paper seeks to establish three critical theses. First, Hacking’s reliance on Crombie leads him to adopt an outdated historiographical position; second, Hacking is unsuccessful in his attempt to distance historical epistemology from epistemic relativism; and third, Hacking has not offered convincing criteria for individuating styles of reasoning.

This paper seeks to defend, develop, and revise Edward Craig's “genealogy of knowledge”. The paper first develops the suggestion that Craig's project is naturally thought of as an important instance of “social cognitive ecology”. It then introduces the genealogy of knowledge and some of its main problems and weaknesses, suggesting that these are best taken as challenges for further work rather than as refutations. The central sections of the paper conduct a critical dialogue between Craig's theory and Wittgenstein's claim–familiar from On Certainty–that common-sense certainties cannot be known. It turns out that Craig's distinction between different stages in the development of our concept of knowledge can illuminate and make plausible Wittgenstein's claim. But it can do so only if Craig's traditional commitment to a central “core” in our concept of knowledge is replaced with the idea of knowledge as a family-resemblance concept.

This paper tries to motivate three desiderata for historical epistemologies: (a) that they should be reflective about the pedigree of their conceptual apparatus; (b) that they must face up to the potentially relativistic consequences of their historicism; and (c) that they must not forget the hard-won lessons of microhistory (i.e. historical events must be explained causally; historical events must not be artificially divided into internal/intellectual and external/social “factors” or “levels”; and constructed series of homogenous events must not be treated as quasi-organisms). Ian Hacking’s work on styles of reasoning and Lorraine Daston’s and Peter Galison’s investigation into epistemic virtues are used to identify the costs of neglecting these desiderata

This paper consists of brief critical comments on Chapter 8, “Personifying Group Agents”, of Christian List’s and Philip Pettit’s book Group Agency (2011). A first set of objections concerns the chapter’s history of ideas. List and Pettit present the history of the idea of corporate personhood as divided between “intrinsicist” and “performative” conceptions. I argue that this distinction does not fit with the historical record and that it makes important political and legal divides and battles invisible. A second set of criticisms builds on perspectives provided by the sociology of knowledge and by John Dewey. My guiding thought here is that “person”, at least when the term is applied to groups, is what political scientists call an “essentially contested concept”. My third set of comments targets the rudimentary political philosophy of List’s and Pettit’s book. I suggest that List’s and Pettit’s corporate personhood theory turns out to be normatively irrelevant; that their concept of “respect” is marred by an ambiguity; and that it remains unclear how their work constitutes progress in guarding against corporate power

Bas van Fraassen’s recent book Scientific Representation: Paradoxes of Perspective modifies and refines the “constructive empiricism” of The Scientific Image in a number of ways. This paper investigates the changes concerning one of the most controversial aspects of the overall position, that is, van Fraassen’s agnosticism concerning the veridicality of microscopic observation. The paper tries to make plausible that the new formulation of this agnosticism is an advance over the older rendering. The central part of this investigation is an attempt to answer Marc Alspector-Kelly’s 2004-criticism of an early version of van Fraassen’s new position. Alspector-Kelly’s contribution it is to date the most extensive attack on van Fraassen’s twenty-first-century work on the topic of microscopic observation. One of the central ideas emerging from the present discussion is a link between the debate over the veridicality of microscopic observation and the issue of the theory-ladenness of experience

In a number of papers and in his recent book, Is Water H₂O? Evidence, Realism, Pluralism (2012), Hasok Chang has argued that the correct interpretation of the Chemical Revolution provides a strong case for the view that progress in science is served by maintaining several incommensurable “systems of practice” in the same discipline, and concerning the same region of nature. This paper is a critical discussion of Chang's reading of the Chemical Revolution. It seeks to establish, first, that Chang's assessment of Lavoisier's and Priestley's work and character follows the phlogistonists' “actors' sociology”; second, that Chang simplifies late-eighteenth-century chemical debates by reducing them to an alleged conflict between two systems of practice; third, that Chang's evidence for a slow transition from phlogistonist theory to oxygen theory is not strong; and fourth, that he is wrong to assume that chemists at the time did not have overwhelming good reasons to favour Lavoisier's over the phlogistonists' views.
