We argue that all general concepts are family resemblance concepts. These include concepts introduced by ostension, such as colour. Concepts of colour and of each of the specific colours are family resemblance concepts because similarities concerning an open-ended range of colour or of appearance features crop up and disappear. After discussing the notion of “same colour” and Wittgenstein's use of the phrase “our colours”, we suggest family resemblance concepts in one tradition can often be extended to family resemblance concepts in (...) another tradition, illustrated by Wittgenstein's use of the words Spiel and “game”.

Readers beware! This book is other than it first seems. Ludwig Wittgenstein’s latest philosophical offering is unlike anything that we have had from him to date. Its preface warns that the Tractatus is no textbook. This is an extreme understatement; really it is a deep puzzle—one that must be handled with great care. As the first lines signal there has been a radical change in the author’s characteristic style. Gone are the ingenious, probing explorations of topics undertaken in his highly (...) fragmentary writings that have been Wittgenstein’s trademark to date. In his new book Wittgenstein abandons the interrogative that his signature vision of and approach to philosophy found in his many masterpieces—The Blue and Brown Books, The Philosophical Investigations, and On Certainty. His previous masterworks have prosecuted a continuous philosophical enterprise designed to expose, resist and reject certain deeply compelling pictures that attract, mesmerize and blind us when it comes to thinking ..

We will look critically at three essays by Cora Diamond concerning Peter Winch's views on the possibility of communication and criticism between language-games. We briefly present our understanding of Winch's approach to philosophy. Then, we argue that Diamond misidentifies Winch's views, taking them to imply language-game relativism or linguistic idealism. When she does raise valid criticisms against language-game relativism, her critical points mainly coincide with things that Winch has already stressed in his own work. That leaves us with the question (...) what their real disagreement amounts to. Finally, we suggest that at the bottom of Diamond's objections lies her failure to appreciate Winch's insights about the place of logic in human intercourse. (shrink)

Christina Lafont has argued that the early Heidegger's reflections on truth and understanding are incompatible with ‘the supposition of a single objective world’. This paper presents her argument, reviews some responses that the existing Heidegger literature suggests, and offers what I argue is a superior response. Building on a deeper exploration of just what the above ‘supposition’ demands, I argue that a crucial assumption that Lafont and Haugeland both accept must be rejected, namely, that different ‘understandings of Being’ can be (...) viewed as offering ‘rival perspectives’ on a common subject-matter. I develop this case by drawing on an alternative account of what a Heideggerian ‘understanding of Being’ might be like. (shrink)

I examine the familiar criterial view of personhood, according to which the possession of personal properties such as self-consciousness, emotionality, sentience, and so forth is necessary and sufficient for the status of a person. I argue that this view confuses criteria for personhood with parts of an ideal of personhood. In normal cases, we have already identified a creature as a person before we start looking for it to manifest the personal properties, indeed this pre-identification is part of what makes (...) it possible for us to see and interpret the creature as a person in the first place. This pre-identification is typically based on biological features. Except in some interesting special or science-fiction cases, some of which I discuss, it is human animals that we identify as persons. (shrink)

The word “picture” occurs pervasively in Wittgenstein's later philosophy. Not only does Wittgenstein often use literal pictures or the notion of mental pictures in his investigations, but he also frequently uses “picture” to speak about a way of conceiving of a matter (e.g. “A picture held us captive” at Philosophical Investigations§115). I argue that “picture” used in this conceptual sense is not a shorthand for an assumption or a set of propositions but is rather an expression of conceptual bedrock on (...) the model of an organising myth. This reading builds primarily on work by Gordon Baker and Stanley Cavell. (shrink)

Drawing Wittgenstein's and Irigaray's philosophies into conversation might help resolve certain misunderstandings that have so far hampered both the reception of Irigaray's work and the development of feminist praxis in general. A Wittgensteinian reading of Irigaray can furnish an anti-essentialist conception of "woman" that retains the theoretical and political specificity feminism requires while dispelling charges that Irigaray's attempt to delineate a "feminine" language is either groundlessly utopian or entails a biological essentialism.

In this essay, I argue that a proper understanding of the historicity of love requires an appreciation of the irreplaceability of the beloved. I do this through a consideration of ideas that were first put forward by Robert Kraut in “Love De Re” (1986). I also evaluate Amelie Rorty's criticisms of Kraut's thesis in “The Historicity of Psychological Attitudes: Love is Not Love Which Alters Not When It Alteration Finds” (1986). I argue that Rorty fundamentally misunderstands Kraut's Kripkean analogy, and (...) I go on to criticize her claim that concern over the proper object of love should be best understood as a concern over constancy. This leads me to an elaboration of the distinct senses in which love can be seen as historical. I end with a further defense of the irreplaceability of the beloved and a discussion of the relevance of recent debates over the importance of personal identity for an adequate account of the historical dimension of love.

I develop a solution to the Sorites Paradox, according to which a concatenation of valid arguments need not itself be valid. I specify which chains of valid arguments are those that do not preserve validity: those that pass the vague boundary between cases where the relevant concept applies and cases where that concept does not apply. I also develop various criticisms of this solution and show why they fail; basically, they all involve a petitio at some stage. I criticise the (...) conviction that if every short argument in a long concatenated argument is valid, so is the long argument: it is, I argue, the result of an unjustified generalisation from the case of arguments that do not employ vague concepts (as in mathematics) to arguments that do employ them. My approach is Wittgensteinian in its “leaving everything as it is,” in its claiming that the “beginning” has been searched too far back (see paper's epigraph) and in its claim that the paradox was generated by a misapplication of a partial picture of the behaviour of arguments. I conclude my paper by comparing and contrasting my approach to the few precedents found in the vagueness literature and by answering a few additional objections that were raised there. (shrink)

Abstract: This essay explores the relation between feminist epistemology and the problem of philosophical skepticism. Even though feminist epistemology has not typically focused on skepticism as a problem, I argue that a feminist contextualist epistemology may solve many of the difficulties facing recent contextualist responses to skepticism. Philosophical skepticism appears to succeed in casting doubt on the very possibility of knowledge by shifting our attention to abnormal contexts. I argue that this shift in context constitutes an attempt to exercise unearned (...) social and epistemic power and that it should be resisted on epistemic and pragmatic grounds. I conclude that skepticism is a problem that feminists can and should take up as they address the social aspects of traditional epistemological problems. (shrink)

The paper reviews the grounds for relativist interpretations of Wittgenstein's later thought, especially in On Certainty . It distinguishes between factual and virtual forms of epistemic relativism and argues that, on closer inspection, Wittgenstein's notes don't support any form of relativism – let it be factual or virtual. In passing, it considers also so-called "naturalist" readings of On Certainty , which may lend support to a relativist interpretation of Wittgenstein's ideas, finds them wanting, and recommends to interpret his positive proposal (...) in On Certainty as a form of "internal rationalism.".

My aim in this paper is to destabilise the brain-is-self thesis, something that is now regarded in some quarters as philosophical commonsense. My contention is that it is the epithelial body that enters into the formation of our sense of self and that largely bears the burden of personal identity as well as playing the key role in grounding our psychological ascriptions. Lacking any sensorimotor or social presence of its own, the brain by itself cannot "underlie" selfhood, but only as (...) part of the whole living human being. If the minded individual is embodied, this must mean more than being embrained. (shrink)

Frederick Olafson criticizes Hubert Dreyfus’s interpretation of BEING AND TIME on a number of points, including the meaning of being, the nature of intentionality, and especially the role of das Man in Heidegger’s account of social existence. But on the whole Olafson’s critique is unconvincing because it rests on an implausible account of presence and perceptual intuition in Heidegger’s early philosophy, and because Olafson maintains an overly individuated notion of Dasein and consequently a one-sided conception of the role of das (...) Man. Unfortunately, since Dreyfus confines his commentary exclusively to Division I, he in effect forgoes any attempt to explain how das Man might be understood as playing the simultaneously constitutive and destructive role Heidegger evidently envisioned for it. I conclude by arguing that the conformity and the conformism represented by das Man are bound together by Heidegger’s notion of standoffishness (Abständigkeit). (shrink)

Karl Jaspers argued that academics must be prepared to accept, perhaps even to welcome, the fact that most students 'will learn next to nothing' from a university education. In this paper I shall argue that, while Jaspers' model is unpersuasive as an ideal and inaccurate as a description, there is an uncomfortable truth lurking behind his forthright but gloomy conclusion; viz., that university teaching pays little direct attention to the needs of the student in the wider world (i.e. to the (...) needs of the student qua employee or qua citizen or even qua rounded human being) and pays even less attention, or perhaps none at all, to the needs and expectations of third parties such as employers. In terms of the political context universities now find themselves in, this is an uncomfortable and embarrassing truth for faculty to admit, for it appears to epitomise a self-regarding and inward looking academy. Yet, despite this, perhaps it is a truth that academics should be prepared to accept, even to welcome. At least, in starting any serious discussion on the nature of a university education, it should be a truth we are prepared to admit. (shrink)

Many philosophers have taken there to be an important relation between personal identity and several of our practical concerns (among them moral responsibility, compensation, and self-concern). I articulate four natural methodological assumptions made by those wanting to construct a theory of the relation between identity and practical concerns, and I point out powerful objections to each assumption, objections constituting serious methodological obstacles to the overall project. I then attempt to offer replies to each general objection in a way that leaves (...) the project intact, albeit significantly changed. Perhaps the most important change stems from the recognition that the practical concerns motivating investigation into personal identity turn out to be not univocal, as is typically thought, such that each of the different practical concerns may actually be related to personal identity in very different ways.

Philosophers have been long interested in delusional beliefs and in whether, by reporting and endorsing such beliefs, deluded subjects violate norms of rationality (Campbell 1999; Davies & Coltheart 2002; Gerrans 2001; Stone & Young 1997; Broome 2004; Bortolotti 2005). So far they have focused on identifying the relation between intentionality and rationality in order to gain a better understanding of both ordinary and delusional beliefs. In this paper Matthew Broome and I aim at drawing attention to the extent to which (...) deluded subjects are committed to the content of their delusional beliefs, that is, to whether they can be regarded as authors of their beliefs (Moran 2001). We consider several levels of commitment one can have to a reported belief, delusional or otherwise, and we distinguish between _ownership_ and _authorship_ of beliefs (Gallagher 2000). After examining some examples of belief authoring (or lack thereof) in psychopathology, we argue that there is no straight-forward and unitary answer to the question whether deluded subjects author their beliefs. Nevertheless, introducing the notion of authorship in the debate can significantly contribute to the philosophical literature on the rationality of delusions and can also have important implications for diagnosis and therapy in psychiatry.

Any good theory of knowledge ascriptions should explain and predict our judgments about their felicity. I argue that any such explanation must take into account a distinction between three ways of using knowledge ascriptions: to suggest acceptance of the embedded proposition, to explain or predict a subject's behavior or attitudes, or to understand the relation of knowledge as such. The contextual effects on our judgments about felicity systematically differ between these three types of uses. Using such a distinction is, in (...) principle, open to both contextualist and pragmatic invariantist accounts of knowledge ascriptions. However, there are some implications pertaining to the use of the “method of cases” in the debate about knowledge ascriptions. (shrink)

Though ancient Pyrrhonian skepticism is apparently based on disagreement, this aspect of skepticism has been widely neglected in contemporary discussion on skepticism. The paper provides a rational reconstruction of the skeptical argument from disagreement that can be found in the books of Sextus Empiricus. It is argued that this argument forms a genuine skeptical paradox that has no fully satisfactory resolution. All attempts to resolve it make knowledge or justified belief either intuitively too easy or impossible.

This paper presents and defends a reappraisal of J.L. Austin’s infamous analogy between saying ‘I know’ and ‘I promise’ in ‘Other Minds.’ The paper has four sections. In §1, I contend that the standard reading of Austin’s analogy is a strawman that distorts the terms of the analogy and superimposes philosophical commitments that Austin was precisely trying to combat. In §§2 and 3, I argue that to understand the point of the analogy we must contextualize ‘Other Minds’ as a response (...) to logical positivism. I recap A.J. Ayer’s influential account of positivism, before arguing that ‘Other Minds’ and its centrepiece analogy should be read as an attack on Austin’s colleague’s organizing positivist assumptions – specifically, descriptivism and the fact/value dichotomy that it props up. My main thesis is that Austin sought to show that epistemic discourse is imbricated with ethical commitments. This reading is anticipated by Cavell, to whom I turn in §4. I bring together insights from across Cavell’s oeuvre to develop this reading of Austin’s analogy and finally to critique certain aspects of it. This paper adds to the recent resurgence in Austin scholarship and aims to get clear the philosophical and historical stakes of his historically maligned analogy. (shrink)

This essay presents a long, detailed, in many ways critical but also appreciative account, of David Bloor’s recent book The Enigma of the Aerofoil. I take that work as the crowning statement of ideas and principles developed over the past four decades by Bloor and other exponents of the ‘strong programme’ in the sociology of scientific knowledge. It therefore offers both a test-case of that approach and a welcome opportunity to review, clarify and extend some of the arguments brought against (...) it by critical realists. This purpose is particularly well served by Bloor’s having here assembled such a wealth of scientific, historical, political and socio-cultural data concerning one specific, very crucial period of research into theories of aerodynamic lift. His book thus provides an exceptionally useful point of engagement for anyone seeking to adjudicate these issues from a critically angled but engaged and constructive standpoint. (shrink)

D. Justin Coates argues that, in ‘Freedom and Resentment’, P. F. Strawson develops a modest transcendental argument for the legitimacy of our moral responsibility practices. I disagree with Coates’ claim that Strawson’s argument provides a justification, in Wittgenstein’s and/or Strawson’s sense of that term, of our responsibility practices. I argue that my interpretation of Strawson solves some difficulties with Coates’ argument, while retaining its advantages.

ABSTRACTOscar Larsson’s essay condemns discursive institutionalism for the “sin” of subjectivism. In reality, however, discursive institutionalism emphasizes the intersubjective nature of ideas through its theorization of agents’ “background ideational abilities” and “foreground discursive abilities.” It also avoids relativism by means of Wittgenstein’s distinction between experiences of everyday life and pictures of the world. Contrary to Larsson, what truly separates post-structuralism from discursive institutionalism is the respective approaches’ theorization of the relationship of power to ideas, with discursive institutionalists mainly focused on (...) persuasive power through ideas, while post-structuralists focus on the structural power in ideas or on coercive power over ideas.

Two Conceptions of Wittgenstein's Contextualism How should we understand Wittgenstein's proposals that "the meaning of a word is its use in the language" and that a name only has a meaning in a language-game? Are they incompatible with occasion-invariant semantics? In this paper I present two leading interpretations of Wittgenstein's contextualism: James Conant's meaning-eliminativism and Charles Travis's meaning-underdetermination. I argue that, even though these two interpretations are very similar, the latter gives a more nuanced account of Wittgenstein's contextualism which does (...) not involve a commitment to the claim that words have no meaning outside immediate contexts of use.

There is a widespread assumption that ordinary language philosophy was killed off sometime in the 1960s or 70s by a combination of Gricean pragmatics and the rapid development of systematic semantic theory. Contrary to that widespread assumption, however, contemporary versions of ordinary language philosophy are alive and flourishing, but going by various aliases—in particular (some versions of) "contextualism" and (some versions of) "experimental philosophy". And a growing group of contemporary philosophers are explicitly embracing the methods as well as the title (...) of ordinary language philosophy and arguing that it has been unfairly maligned and was never decisively refuted. In this overview, I will outline the main projects and arguments employed by contemporary ordinary language philosophers, and make the case that updated versions of the arguments made by ordinary language philosophers in the middle of the twentieth century are attracting renewed attention.

In “Correspondence to Reality in Ethics”, Mario Brandhorst examines the view of ethics that Wittgenstein took in his later years. According to Brandhorst, Wittgenstein leaves room for truth and falsity, facts, correspondence and reality in ethics. Wittgenstein's target, argues Brandhorst, is objectivity. I argue that Brandhorst's arguments in favour of truth, facts, reality and correspondence in ethics invite similar arguments in favour of objectivity, that Brandhorst does not recognise this because his conception of objectivity is distorted by a Platonist picture (...) and that he misinterprets the passage which he takes to support a Wittgensteinian case against objectivity.

G.E. Moore’s writings on external world skepticism show us, in broad outline, how to dispense with external world skepticism in a way that is satisfying, intellectually responsible, and yet avoids engaging in constructive epistemological theory-building altogether. His work thus reveals something very important about the relation between epistemology and ordinary life, and also about what it would take to reach a satisfying resolution of certain sorts of perennial philosophical problems.

This paper establishes a dialogue between the later works of Wittgenstein, those of Cavell and the novels of J. M. Coetzee concerning the problem of violence, authority and the authoritative voice. By drawing on J. M. Coetzee's Waiting for the Barbarians and Diary of a Bad Year, the paper discusses lessons and insights on the nature of violence and the ways in which it can be accepted as “normal.” The term “normalization” is used in order to show how violence and (...) cruelty can become a “form of life” that develops according to its own actors, cultural practices and legitimacies.

In the first experiment, I exhibit unreliable judgment about the primeness or divisibility of four-digit numbers, in contrast to a seeming Excel program. In the second experiment, I exhibit an imperfect memory for arbitrary-seeming three-digit number and letter combinations, in contrast to my seeming collaborator with seemingly hidden notes. In the third experiment, I seem to suffer repeated defeats at chess. In all three experiments, the most straightforward interpretation of the experiential evidence is that something exists in the universe that (...) is superior in the relevant respects – theoretical reasoning (about primes), memorial retention (for digits and letters), or practical reasoning (at chess) – to my own solipsistically-conceived self.

The position of the philosophy of education in theoretical or practical philosophy was the main subject of debate between Paul Hirst and Wilfred Carr. In his support for practical philosophy, Carr argues that in order to bridge the theory/practice gap and deconstruct the illusory intactness of philosophy of education from developments in the practical realm, philosophy of education should be assumed as a branch of practical philosophy. Opposed to this argument, Hirst holds that philosophy of education is a second-order activity (...) and a theoretical matter. Even though both viewpoints seem to be reductive, it is argued here that the controversy of Hirst and Carr on theoretical/practical philosophy of education is more a pseudo-problem than a real one. This is because Hirst does not dismiss the reflection on action as a source of philosophical knowledge, nor does Carr in fact avoid a second-order activity in his endeavour in philosophy of education. Nonetheless, it is argued that we should celebrate a moderate dualism in the case of theoretical and practical reason. (shrink)

The paper argues that dreams consist partly in an awareness or experience of the conceptual fabric of our existence. Since what we mean by reality is intimately tied to the concepts given in our experience, dreams are therefore also partly an awareness of the fabric of what we mean by being itself and in general, that is, by objective as well as subjective reality. Further, the paper argues that this characteristic of dreams accounts for several other, more specific aspects of (...) dreams and their possible interpretation, and that it allows us to see how these aspects are related to each other. These more specific aspects are the peculiar types of conceptual or logical relations and transitions that occur within dreams, dreams’ distinctive feeling texture, and some dimensions of the grounds and nature of suitable methods of interpreting dreams.

The dissertation examines the nature and epistemic implications of epistemic source circularity. An argument exhibits this type of circularity when at least one of the premises is produced by a belief source the conclusion says is legitimate, e.g. a track record argument for the legitimacy of sense perception that uses premises produced by sense perception. In chapter one I examine this and several other types of circularity, identifying relevant similarities and differences between them. In chapter two I discuss the differences (...) between internalist and externalist analyses of justification. I examine in detail foundationalist and non-foundationalist versions of internalism, and go on to consider how one might characterize externalism: either negatively, by denying particular internalist theses, or positively, in terms of a theory offering different conditions for justification. I discuss the views of reliabilist foundationalists at length. In chapter three I present the internalist objection to externalism that the latter mistakenly permit one to be justified in believing the conclusion of an epistemic source circular inference. I explain the externalists' response that it is not in virtue of their externalism that they permit epistemic source circularity but rather their foundationalism; thus, internalist foundationalists must permit epistemic source circularity as well. I evaluate the positions of several internalists, most of them explicitly foundationalists, and argue that they too cannot avoid permitting epistemic source circularity. In the final chapter I consider whether such circularity is vicious, even though both internalist and externalist foundationalists permit it. I argue that one can sustain an objection to epistemic source circularity by imposing a non-question-begging requirement on justification and explain how respecting this requirement leads one to a non-foundationalist view. I conclude by considering the objection that question-begging leads to a certain arbitrariness in belief formation that should give the foundationalist pause when it comes to determining, at the beginning of inquiry, which beliefs are justified and which are not. The dissertation is primarily concerned with making clear the possible skeptical and non-skeptical positions one can take towards epistemic source circularity. I do not argue for the truth of a particular metaepistemology. (shrink)

Plusieurs auteurs se sont inspirés des thèses du deuxième Wittgenstein pour proposer une nouvelle approche en sciences sociales qui viserait la justification plutôt que l'explication de l'action.

Consider the following epistemological principle:KR: A knowledge source K can yield knowledge for subject S only if S knows K is reliable.Traditional epistemologists face a dilemma: either reject KR and confront what Stewart Cohen calls “the Problem of Easy Knowledge” or embrace KR and deny that unreflective beings can possess knowledge. In order to avoid this dilemma, an epistemological theory must allow for knowledge on the part of unreflective beings without falling prey to the problem of easy knowledge. I argue (...) that the epistemology of the dying Wittgenstein, presented posthumously in On Certainty, avoids the dilemma. (shrink)

It is argued in this article that the concept of practice is one of the key concepts in Wittgenstein's later philosophy. It partly replaces his earlier talk about the inexpressible. ?The practice has to speak for itself, as Wittgenstein succinctly puts it. The concept of practice not only points to the ways in which the unity of our concepts are underpinned, as Gordon Baker has it, it also comprises the skills involved in handling the conceptualized phenomena, our prereflective familiarity with (...) them, expressed in the sureness in our behaviour towards them, and the judgmental power exercised in applying or withholding a given concept on a particular occasion. These factors are all relevant to the establishment of knowledge, but they cannot themselves be fully and straightforwardly articulated by verbal means. Nevertheless, they represent what we go by when we apply concepts and other types of rules. To follow a rule is what Wittgenstein calls a practice. The sketched analysis of this concept makes us understand better how it is possible to apply a rule without the support of another rule. It also makes us realize in what sense one is justified in talking about tacit knowledge in connection with the application of concepts and rule?following in general. Quite a lot hangs on seeing the world aright at this point. (shrink)

Epistemology, I will argue, is of crucial importance to the sociology of knowledge— not just by way of definition of the phenomenon under study, but also because approaches to the sociology of knowledge rely on too-often implicit epistemological stances. I will make this argument through a series of categorizations: first, I will classify the field of epistemology into its three main forms; second, I will classify the sociology of knowledge into epistemological categories; third, I will classify the sociology of science (...) into these same categories. All the while, I will be making an argument for an empirical epistemology and "agnostic" studies of knowledge. This article does not cover the field of epistemology exhaustively, but tries to offer an orderly overview of classic positions for the benefit of social scientists. (shrink)

Reflection on the history of skepticism shows that philosophers have often conjoined as a single doctrine various theses that are best kept apart. Some of these theses are incredible – literally almost impossible to accept – whereas others seem quite plausible, and even verging on the platitudinous. Mixing them together, one arrives at a view – skepticism – that is as a whole indefensible. My aim is to pull these different elements apart, and to focus on one particular strand of (...) skepticism that deserves sustained and respectful attention. The strand I have in mind I will refer to as epistemic defeatism. Roughly, in its most global form, it is the view that, in the final analysis, we have no good evidence for the truth of any proposition. Working through various historical texts, I attempt to untangle epistemic defeatism from neighboring views, and in particular to establish its independence from questions about knowledge. Having thus established the view's autonomy, I turn to the options for self-consciously accepting defeat. One may despair or one may have faith. But I will ultimately propose that the most attractive option – the option that preserves the most of our epistemic integrity – is to have hope. (shrink)

After describing Wittgenstein's notion of ‘certainty’, in this article I provide four arguments to demonstrate that no certainty can be acquired at will. Specifically, I argue that, in order to assimilate a certainty, it is irrelevant whether the individual concerned has found a ground that seemingly justifies that certainty; has a given mental state; is willing to accept the certainty on the proposal of a persuader; or tries to act according to the certainty involved. Lastly, I analyse how each of (...) these arguments is reflected in the way children acquire certainties. (shrink)
