Many contributors of the debate about knowledge by testimony concentrate on the problem of justification. In my paper I will stress a different point – the concept of testimony itself. As a starting point I will use the definitional proposal of Jennifer Lackey. She holds that the concept of testimony should be regarded as entailing two aspects – one corresponding to the speaker, the other one to the hearer. I will adopt the assumption that we need to deal with both (...) aspects. Nevertheless, I will show that her concept – which suggests regarding testimony as an act of communication conveying information – is too broad and, therefore, I will end up with a different twofold definition.

The following inquiry pursues two interlinked aims. The first is to understand Wittgenstein's idea of non-foundational certainty in the context of a reading of On Certainty that emphasizes its Pyrrhonian elements. The second is to read Wittgenstein's remarks on idealism/radical skepticism in On Certainty in parallel with the discussion of rule-following in Philosophical Investigations in order to demonstrate an underlying similarity of philosophical concerns and methods. I argue that for the later Wittgenstein, what is held certain in a given context (...) of inquiry or action is a locally transcendental condition of the inquiry or action in question. In On Certainty, Wittgenstein's analysis of the difference between knowledge and certainty forms the basis of his critique of both Moore's "Proof" and radical skepticism. This critique takes the shape of rejection of a presupposition shared by both parties, and utilizes what I identify as a Pyrrhonian-style argument against opposed dogmatic views. Wittgenstein's method in this text involves describing epistemic language-games. I demonstrate that this is consistent with the rejection of epistemological theorizing, arguing that a Wittgensteinian "picture" is not a theory, but an impressionistic description that accomplishes two things: (i) throwing into relief problems with dogmatic theories and their presuppositions, and (ii) describing the provenance of linguistic and epistemic practices in terms of norms grounded in convention. Convention, in turn, is not arbitrary, but grounded in the biological and social natures of human beings--in what Wittgenstein calls forms of life. Thus there is a kind of naturalism in the work of the later Wittgenstein. It is a naturalism that comes neatly dovetailed with Pyrrhonism--a combination of strategies traceable to Hume's work in the Treatise. I read Hume as someone who develops the Pyrrhonian method to include philosophy done "in a careless manner," and argue that Wittgenstein adopts a similar method in his later works. Finally, I explain the deference to convention in the work of both Hume and Wittgenstein by reference to a passage in Sextus' Outlines, on which I provide a gloss in the final chapter of this work.

Different philosophers tried ways to restore the role of reason in ethics. This shift in the philosophical climate was influenced by--or was at least in accordance with--the thought of the later Wittgenstein. In particular, this article will consider the relevance of Wittgenstein for cognitivist views, such as that of S. Toulmin, relativist like G. Harman, and British moral realists like S. Lovibond and J. McDowell. In fact, Wittgenstein is one of the founding fathers of antifoundationalism. He gives us the hopeful (...) insight that the end of foundationalism does not necessarily imply the end of moral philosophy but must be considered a new start of it. (edited). (shrink)

It is possible to pursue philosophy with a clarificatory end in mind. Doing philosophy in this mode neither reduces to simply engaging in therapy or theorizing. This paper defends the possibility of this distinctive kind of philosophical activity and gives an account of its product—non-theoretical insights—in an attempt to show that there exists a third, ‘live’ option for understanding what philosophy has to offer. It responds to criticisms leveled at elucidatory philosophy by defenders of extreme therapeutic readings and clearly demonstrates (...) that in rejecting the latter one cannot assume Wittgenstein’s approach to philosophy was theoretically based by default.

Interpretations of Wittgenstein’s work notoriously fuel debate and controversy. This holds true not only with respect to its main messages, but also to questions concerning its unity and purpose. Tradition has it that his intellectual career can be best understood if carved in twain; that we can get a purchase on his thinking by focusing on and contrasting his, “two diametrically opposed philosophical masterpieces, the Tractatus Logico-Philosophicus (1921) and the Philosophical Investigations (1953)” (Hacker 2001, 1). This is allegedly justified by (...) the supposition that these provide us with two, distinctive, “powerful complete world-pictures” (Hacker 2001, p. viii). Others object; holding that this simple division fails to take account of all the major breaks. They claim that, minimally, we ought to recognise at least three major moments in the progression of Wittgenstein's thought, taking stock of a final period in which On Certainty dominates. Still others reject the idea that the best interpretative results will come from regarding the development of his thinking in the stark terms of involving 'complete' changes of mind at all. On the contrary, they argue that we will better understand his works if we emphasise their methodological continuity. For anyone interested in these matters, The Voices of Wittgenstein is an absolutely fascinating collection. It presents us with dictations by Wittgenstein and a series of other writings with his solid imprint; all of these were compiled and arranged (if not partly composed) by Waismann. Although Baker is clear that they did not come with any explicit account of their origin or purpose, it is possible to draw some reasonable inferences about these by consideration of the salient historical facts.

H.-J. Glock has made important contributions to discussions of rationality, reasons, and rules. This chapter addresses four conceptions of rationality that Glock identifies. One of these conceptions of rationality is that rationality consists in responsiveness to reasons. This chapter goes on to consider the idea that reasons became prominent in normative ethics because of their usefulness in articulating moral pluralism. The final section of the chapter connects reasons and rules and contends that both are ineliminable.

Advancing our understanding of one of the most influential 20th-century philosophers, Robert Vinten brings together an international line up of scholars to consider the relevance of Ludwig Wittgenstein's ideas to the cognitive science of religion. Wittgenstein's claims ranged from the rejection of the idea that psychology is a 'young science' in comparison to physics to challenges to scientistic and intellectualist accounts of religion in the work of past anthropologists. Chapters explore whether these remarks about psychology and religion undermine the frameworks (...) and practices of cognitive scientists of religion. Employing philosophical tools as well as drawing on case studies, contributions not only illuminate psychological experiments, anthropological observations and neurophysical research relevant to understanding religious phenomena, they allow cognitive scientists to either heed or clarify their position in relation to Wittgenstein's objections. By developing and responding to his criticisms, Wittgenstein and the Cognitive Science of Religion offers novel perspectives on his philosophy in relation to religion, human nature, and the mind.

In On Certainty, Wittgenstein formulates several criticisms against skepticism about our knowledge of the external world. My goal is to show that Wittgenstein does not here offer a convincing answer to the skeptical problem. First, I will present a strong version of the problem, understanding it as a paradoxical argument. In the second part, I will introduce and raise problems for two pragmatic responses against skepticism that appear in On Certainty. Finally, I will present some of Wittgenstein’s logical criticisms against (...) skepticism, which may initially be considered strong, because they seem to refute some skeptical assumptions. They concern Wittgenstein’s ideas that it is logically impossible to doubt and to be mistaken about Moorean propositions, and that these propositions don’t have a truth-value. But even these, I intend to show, do not really challenge skepticism, for they are not well grounded. (shrink)

My goal here is to assess whether Wittgenstein’s metaphilosophical conception of a descriptive philosophy is in accordance with his philosophical practice. I argue that Wittgenstein doesn’t really limit himself to description when he criticizes Moore’s use of the verb “to know”. In On Certainty, Wittgenstein argues that Moore’s claims of knowledge are at odds with the everyday use of the verb “to know”, because, among other things, they don’t allow the possibility of justification. That is, Wittgenstein considers that proper, everyday (...) claims of knowledge require the possibility of justification. What I try to show is that this idea cannot be derived from the mere observation and description of knowledge claims in ordinary language. I conclude that Wittgenstein’s treatment of the verb “to know” constitutes an inconsistency between his metaphilosophical posture and his philosophical practice. (shrink)

This paper considers the connection between concepts, conceptual schemes and grammar in Wittgenstein’s last writings. It lists eight claims about concepts that one can garner from these writings. It then focuses on one of them, namely that there is an important difference between conceptual and factual problems and investigations. That claim draws in its wake other claims, all of them revolving around the idea of a conceptual scheme, what Wittgenstein calls a ‘grammar’. I explain why Wittgenstein’s account does not fall (...) prey to Davidson’s animadversions against the idea of a conceptual scheme as a force operating on a pre-conceptual content. In the sequel I deny that the distinction between grammatical and empirical propositions disappears in the last writings: it is neither deliberately abandoned, nor willy-nilly undermined by the admission of hinge propositions in On Certainty or by the role accorded to agreement in judgement.

Our approach to the liar paradox is based on the Wittgensteinian approach to semantic and logical paradoxes. The main aim of this article is to point out that the liar sentence is only seemingly intelligible, and that it has not been given any sense. First, we will present the traditional solutions of the paradox, especially those which we call modificational. Then we will determine what the defects of these solutions are. Our main objection is that the modificational approaches assume that (...) we can express in languages certain senses which are improper. Next, we will explain why we think that the liar sentence is a mere nonsense. This sentence does not have any role in any language game – it is completely useless. We will also respond to several objections to our approach. 1. That it is not consistent with the principle of compositionality of sense. 2. According to the Quineian philosophy of logic, paradoxical sentences can be conceived as false assumptions leading to crises of logical paradigms. 3. The liar sentence seems to be, contrary to our approach, intelligible. (shrink)

This paper is more than a plea for Rhees’ reading of the work of Wittgenstein (particularly of On Certainty). My interest in Rhees’ interpretation lies on its resemblance with my own reading, on the one hand, and on its being (surprisingly) unmentioned by other interpreters, on the other. The two core aims of this paper focus on Rhees’ main ideas. First, I argue that although certain facts that are accepted beyond doubt belong to the method, which in turn is included (...) in grammar, this does not mean that these facts are expressions of rules of grammar. Second, I argue that grammar is not conditioned by a certain class of facts (i.e. general facts of nature), but a language-game is possible because we do not call in question certain facts (i.e. grammar is not conditioned by something like ontology). The point is that those facts that are not called in question are beyond truth and falsity, but this does not mean that these facts must be true. The logical role these facts (and the sentences used to express them) play in a language-game is not that of being true or false. Moreover, grammar itself constitutes what is meant by ‘object’, ‘fact’, or ‘general fact of nature’. (shrink)

Wittgenstein’s remarks on religious and magical practices are often thought to harbour troubling fideistic and relativistic views. Unsurprisingly, commentators are generally resistant to the idea that religious belief constitutes a ‘language‐game’ governed by its own peculiar ‘rules’, and is thereby insulated from the critical assessment of non‐participants. Indeed, on this fideist‐relativist reading, it is unclear how mutual understanding between believers and non‐believers (even between different sorts of believers) would be possible. In this paper I do three things: (i) show why (...) the fideist‐relativist reading of Wittgenstein is not wildly implausible (Sections 1–2); (ii) argue that, despite its initial plausibility, this reading fails to take into account Wittgenstein’s naturalism (Sections 3–4); and (iii) explain what sort of naturalism this is, and how it sheds light on Wittgenstein’s remarks on religious belief (Sections 5–6).

In a remark written sometime between 1933 and 1943, Wittgenstein suggests that philosophy ought really to be written as one “writes a poem.” Around this time he also talks of simile as the “best thing” in philosophy. In this paper I consider what it would mean to take such claims seriously. Through examining newly discovered material from the Skinner manuscripts, I offer an analysis of Wittgenstein's approach to literary techniques and see how this impacts on his conception of philosophy.

Wittgenstein’s remarks in On Certainty about the acquisition of child language have gone nearly unnoticed for the commentators of his work. In this paper, I analyze some of those remarks to shed light on the main questions posed in On the categorical distinction between knowledge and certainty; the nature of language-games; the refutation of skepticism and, above all, the challenges involved by learning to believe.

This paper makes use of a new development in social psychology, Positioning Theory, the study of the way rights and duties are ascribed, attributed and justified to and by individuals in local social groups. It links this theory with a generally Vygotsky inspired approach to understanding the means by which people are brought into terrorist networks. Focusing on the use of the Internet as a device to bring mentor and novice together, the unique role of chat rooms and personal conversations (...) made possible by the Internet in this psychological process is revealed. Examining Vygotsky's ideas about the influence of a collective identity on the development of individual identities by psychological symbiosis in the Zone of Proximal Development sheds new light on the positioning of terrorist recruits. Incorporating Wittgenstein's concept of hinges into understanding the groundings of individual positions explains how the jihadist form of life turns on the unexamined grounding of beliefs about the non-believers.

In recent publications, Harré and Llored Challenges of cultural psychology, Routledge, London, pp 189–206, 2018a; Philosophy, 93:167–186, 2018b; The analysis of practices, Cambridge Scholars Publishing, Newcastle upon Tyne, 2019) take the role of philosophy of science as a digging out of the ‘hinges’, that are the tacit elements of a discipline. In this perspective, the philosophy of chemistry consists, at least partly, in making explicit the hinges on which chemistry turns and in examining their origins and logical status. In this (...) paper, we propose to query Harré and Llored’s research approach in the case study of the element chlorine. Whereas most early nineteenth-century textbooks define the element as the endpoint of chemical decomposition, the controversy surrounding the element chlorine reveals implicit criteria that surpass operational indivisibility. From 1810 onwards, Davy argued that chlorine was a simple substance; yet, even though it had been known to be indecomposable using the strongest instruments available, the widespread acceptance of chlorine took until 1816–1818. The main factor that contributed to the resolution of the debate was the discovery of iodine, an analogous element which provided new theoretical coherence between explanations of different phenomena :247–258, 1959). Thus, the idea that elements should qualitatively resemble each other is an implicit belief which appears to have been shared by many prominent chemists of the time, despite the fact that it was not stated as part of the definition of the chemical element. Could we assert that this idea was a ‘hinge’ around which the notion of chemical element revolved? Our talk will answer this question. (shrink)
