What are the limits of Left Wittgensteinianism's point- and need-based account of conceptual change? Based upon Wittgenstein's account of certainty and the riverbed analogy for conceptual change in On Certainty, the question is raised whether Queloz and Cueni's redevelopment of Left Wittgensteinianism can account for the multiplicitous forms of change these concepts are subject to. I argue that Left Wittgensteinianism can only partially do so, because it overemphasises the role of criticism-driven conceptual change, due to its focus on (...) the reason-based contingency of the practices of a local ‘we’. In response, it is argued that Left Wittgensteinianism should be fortified with (i) gradual changes to concepts' sociocultural constraints that concept-users are unaware of and (ii) evolutionary and environmental changes to the biological determinants of natural constraints of conceptual cores. In the end, there are conceptual practices like holding for certain that are generally, and fully contingent, but simultaneously inevitable not only for ‘us’ but also for many other delimitations of ‘we’. Subsequently, the compatibility of this Wittgensteinian account of conceptual change with pragmatic genealogy is discussed. It is concluded that thinking about conceptual changes to practices cannot be about the possibility of criticism alone nor succeed without the inclusion thereof. (shrink)

While Cavell is well known for his reinterpretation of the later Wittgenstein, he has never really engaged himself with post-Investigations writings like On Certainty. This collection may, however, seem to undermine the profoundly anti-dogmatic reading of Wittgenstein that Cavell has developed. In addition to apparently arguing against what Cavell calls ‘the truth of skepticism’ – a phrase contested by other Wittgensteinians – On Certainty may seem to justify the rejection of whoever dares to question one’s basic presuppositions. According (...) to On Certainty, or so it seems, the only right response to someone with different certainties is a reproach like ‘Fool!’ or ‘Heretic!’. This article aims to show that On Certainty need not be taken to prove Cavell wrong. It explains that Wittgenstein, in line with the first two parts of The Claim of Reason, does not reject scepticism out of hand but rather questions the sceptic’s self-understanding. Using arguments from Part Three of The Claim, the article moreover argues that a confrontation with divergence calls for self-examination rather than self-righteousness. Precisely because Wittgenstein acknowledges ‘the groundlessness of our believing’ or, in Cavellian terms, ‘the truth of skepticism’, he is not the authoritarian thinker that some have taken him to be.

Wittgenstein's book On Certainty which was first published in 1969, eighteen years after his death, is a collection of notes which he composed during the last eighteen months of his life. As his editors explain in their preface, these notes, which were written at four different periods, are all in the form of a first draft. They are more repetitive than they no doubt would have been if Wittgenstein had been able to revise them. Even so, they are characteristically (...) succinct and penetrating, and the argument which they develop is easier to follow than that of the general run of Wittgenstein's later work. (shrink)

Annalisa Coliva (Int J Study Skept 10(3–4):346–366, 2020) asks, “Are there mathematical hinges?” I argue here, against Coliva’s own conclusion, that there are. I further claim that this affirmative answer allows a case to be made for taking the concept of a hinge to be a useful and general-purpose tool for studying mathematical practice in its real complexity. Seeing how Wittgenstein can, and why he would, countenance mathematical hinges additionally gives us a deeper understanding of some of his latest thoughts (...) on mathematics. For example, a view of how mathematical hinges relate to Wittgenstein’s well-known river-bed analogy enables us to see how his way of thinking about mathematics can account nicely for a “dynamics of change” within mathematical research—something his philosophy of mathematics has been accused of missing (e.g., by Robert Ackermann (Wittgenstein’s city, The University of Massachusetts Press, Amherst, 1988) and Mark Wilson (Wandering significance: an essay on conceptual behavior, Oxford University Press, Oxford, 2006). Finally, the perspective on mathematical hinges ultimately arrived at will be seen to provide us with illuminating examples of how our conceptual choices and theories can be ungrounded but nevertheless the right ones (in a sense to be explained).

In On Certainty, the important, but to many readers obscure, twentieth century Austrian philosopher, Ludwig Wittgenstein, provides not only a brilliant solution to a previously intractable philosophical problem, but also the elements of an entirely new way of approaching this and similar longstanding, apparently un-resolvable, problems. In these notes he re-conceives the problem of radical skepticism–the claim that we can never really be certain of anything except the contents of our own minds–as a kind of philosophical “disease” of thought. (...) His approach to the problem, which I will emphasize is similar to the treatment of disease, has two main goals: -/- (1) bring about an awareness in the philosopher that this kind of extreme skepticism is not a methodological approach to be taken seriously, and, with this awareness, -/- (2) an attempt to replace this radical skepticism with a practical, Common Sense framework. -/- Implicit in Wittgenstein’s approach are a number of strategies found in a contemporary approach to psychotherapy known as Cognitive Behavioral Therapy (CBT). These strategies, along with philosophical methods and scientific practices rooted in the Scottish School of Common Sense, seek to diagnose and treat irrational thoughts and beliefs that often emerge (and re-emerge) in the discipline of philosophy. The aim is to provide the philosopher with tools necessary to adjust and reshape these irrational, self-defeating thoughts and beliefs into something new, something healthy. (shrink)

Written over the last 18 months of his life and inspired by his interest in G. E. Moore's defence of common sense, this much discussed volume collects Wittgenstein's reflections on knowledge and certainty, on what it is to know a proposition for sure.

On Certainty continues Rescher s longstanding practice of publishing occasional studies that form part of a wider program of investigation of the scope and limits of rational inquiry in the pursuit of understanding. And pragmatism forms a subtextual Leitmotiv of these essays, seeing that the linking idea at work throughout is that knowledge is a tool for the management of our theoretical and practical affairs, and that what we ask of it is serviceability for the uses we have in (...) view.".

In lieu of an abstract, here is a brief excerpt of the content:47. Hausman on Certainty and Necessity in Hume Professor Hausman in the course of a painstaking and often illuminating examination of my paper "Hume on Intuitive and Demonstrative Inference" fortunately has occasion to make some positive suggestions of his own regarding the best way to interpret Hume's philosophy. One of the most interesting and provocative of these suggestions is that we should discount Hume's claim to have found (...) an impression of reflection which is at the same time one of necessity. Rather, we should regard the impression of reflection in question as one of certainty. Such a manner of proceeding would, moreover, in Hausman' s view have the advantage öf explaining why we all believe that causal connections are necessary when in fact they are not. For the same impression of certainty, as Hausman envisages it, will be generated by both the cognitive act of comparing two relata wherein genuine necessity is reflected and the determination of an idea by a preceding impression wherein causal inference consists and wherein genuine necessity plays no role. But how can Hausman be so sure that they will be the same? For he insists that the cognitive act of comparing two relata is radically different from the determination of an idea by a preceding impression. Why then should we expect that observation of the two should generate comparable feelings of certainty? And if they do not generate comparable feelings of certainty what is the purpose served by postulating them? Moreover, I use the term "postulating" advisedly: by Hausman' s own admission there is little or no textual evidence for their presence in Hume's theory of causal inference. Hausman' s purpose would be no worse served - at least incoherence would be avoided - by emphasizing what a cognitive act of comparing two relata and a determination of an idea by a preceding impression have in common as opposed to what distinguishes them. They have, moreover, more in 48. common than he seems to think. For, while the one requires reflection according to Hume and the other does not, they 2 both involve a determination of the mind. Nor is Hume's use of the concept of intuition in connection with the former incompatible with such a determination, as Hausman seems to think. On the contrary, it implies it. For intuition as Hume understands it seems to pertain to immediate inference. And such inferences consist as far as he is concerned in determinations of the mind to move from one 3 idea to a second one. Indeed, it is just the supposed infallibility of such determinations that allows him to distinguish them from the more haphazard principles of as4 sociation. A cognitive act of comparing two relata and a determination of an idea by a preceding impression are sufficiently alike, then, to explain why we all believe that causal connections are necessary when in fact they are not. This does not mean, of course, that necessity need reside in such a cognitive act of comparing. As a matter cf fact, as we shall see in a moment, this is not the view that Hume usually takes of the matter. But a cognitive act of comparing, as we shall also see in a moment, is close enough to the area in which necessity does reside to allow Hume to explain in the manner indicated how our mistaken belief about causal connections arises. Hausman' s comparable feelings of certainty are not required. Nor has Occam's razor finished cutting. More specifically, the idea of real necessity of which Hausman speaks could have, as far as I can see, no role to play in Hume's philosophy which is not already played by the cognitive act of comparing two relata. There is, moreover, no such idea anymore than there is any idea of causal necessity. The "idea of entities in a particular sort of relation" presumably like resemblance will not do. For resemblance is not necessity. And to say as Hausman does that "it is because we can read off a resemblance, say, that we pronounce the relationship necessary" is to state a problem, not to 49.??. 6 solve it. What then is the solution? It seems... (shrink)

Wittgenstein's last work, On Certainty , is widely regarded as his third masterpiece of philosophy and one of his most enigmatic writings. On Certainty explores the ways in which claims of indisputable knowledge are expressed, and how language forms the basis of such claims. On Certainty has largely been read as representing a break with Wittgenstein's previous thinking, but this study places these ideas firmly in the development of his thought since the 1930s. Wittgenstein on Certainty (...) and Doubt illuminates Wittgenstein's examination of the logical features of epistemic terms—such as 'know', 'believe' and 'doubt'—and his interrogation of the foundations of human knowledge, the extent to which our knowledge is immune from doubt, and the conflicts between different articulations of knowledge.

This radical reading of Wittgenstein's third and last masterpiece, On Certainty, has major implications for philosophy. It elucidates Wittgenstein's ultimate thoughts on the nature of our basic beliefs and his demystification of scepticism. Our basic certainties are shown to be nonepistemic, nonpropositional attitudes that, as such, have no verbal occurrence but manifest themselves exclusively in our actions. This fundamental certainty is a belief-in, a primitive confidence or ur-trust whose practical nature bridges the hitherto unresolved categorial gap between belief (...) and action. (shrink)

The paper focuses on the role of relativistic ideas in Wittgenstein’s philosophy. In particular, it focuses on On Certainty (1969), where in (305), Wittgenstein explicitly invokes Einstein’s theory of relativity: “Here once more there is needed a step like the one taken in relativity theory.” The aim of the paper is to establish a connection between Wittgenstein and Einstein that is both theoretically and exegetically sound. In particular, the paper argues that Wittgenstein’s reaction to scepticism closely resembles Einstein’s reaction (...) to the ether. (shrink)

I can’t help but like a book that calls Wittgenstein the greatest philosopher since Kant and then proceeds to show how On Certainty, a manifestly brilliant but understudied book, sheds light on matters under current debate. It is pleasant to see a highly skilled contemporary put texts from the later philosophy under close scrutiny and mine them for insight, and that outside the bounds of familiar Wittgenstein scholarship.

In this paper, I survey the way Wittgenstein reacts to radical philosophical doubt in his On Certainty.He deems skeptical doubt in some important cases idle, pointless or otherwise negligible. I point out that several passages of On Certainty make it difficult to judge whether Wittgenstein intends to address a skeptic or a metaphysical idealist. Drawing attention to the anti-skeptical nature of Berkeley’s idealism, I go on to argue that the question is far from trivial: rather, it affects the (...) way we should evaluate Wittgenstein’s arguments in On Certainty in general. I finally attempt to explain why Wittgenstein remained ambiguous about the target of his arguments, and discuss the possibility of making room for the idealism/skepticism distinction in On Certainty’s framework.

In the year 2060, sophisticated investigative tools can help catch a killer. But there are some questions even the most advanced technologies cannot answer... Harlan Coben says, “J.D. Robb’s In Death novels are can’t-miss pleasures.” Her latest is no exception, as the priest at a Catholic funeral mass brings the chalice to his lips—and falls over dead... When Detective Lieutenant Eve Dallas confirms that the consecrated wine contained potassium cyanide, she’s determined to solve the murder of Father Miguel Flores, despite (...) her discomfort with her surroundings. It’s not the bodegas and pawn shops of East Harlem that bother her, though the neighborhood is a long way from the stone mansion she shares with her billionaire husband Roarke. It’s all that holiness flying around at St. Christobal’s that makes her uneasy. A search of the victim’s sparsely furnished room reveals little—except for a carefully hidden religious medal with a mysterious inscription, and a couple of underlined Bible passages. The autopsy reveals more: faint scars of knife wounds, a removed tattoo—and evidence of plastic surgery suggesting “Father Flores” may not be the man his parishioners thought. Now, as Eve pieces together clues that suggest identity theft, gang connections, and a deeply personal act of revenge, she hopes to track down whoever committed this unholy act. Until a second murder—in front of an even larger crowd of worshippers—knocks the whole investigation sideways.

This paper examines the relevance of Wittgenstein’s On Certainty to the contemporary debate regarding the problem of radical scepticism. In particular, it considers two accounts in the recent literature which have seen in Wittgenstein’s remarks on “hinge propositions” in On Certainty the basis for a primarily epistemological anti-sceptical thesis—viz., the inferential contextualism offered by Michael Williams and the ‘unearned warrant’ thesis defended by Crispin Wright. Both positions are shown to be problematic, both as interpretations of Wittgenstein and as (...) anti-sceptical theses. Indeed, it is argued that on a reading of On Certainty which has Wittgenstein advancing a primarily epistemological thesis, there is in fact strong evidence to suggest that Wittgenstein thought that no epistemic response to the sceptic was available—at best, it seems, only a pragmatic antisceptical thesis is on offer. Such a conclusion is not without import to the present debate regarding radical scepticism, however, since it poses a general challenge for how the sceptical argument is conceived in the contemporary literature.

This article examines how deduction preserves certainty and how much certainty it can preserve according to Descartes’s Rules for the Direction of the Mind. I argue that the certainty of a deduction is a matter of four conditions for Descartes. First, certainty depends on whether the conjunction of simple propositions is composed with necessity or contingency. Second, a deduction approaches the certainty of an intuition depending on how many “acts of conceiving” it requires and—third—the complexity (...) or difficulty of the acts of thinking, which is determined by the content of the thoughts and on external factors. Fourth, certainty depends on the intellectual aptitude of the person using the deduction. A deduction lacks certainty when it relies on memory such that it is not apprehended with immediacy. However, the mental capacity and speed of a mind can be increased by training the special mental faculties of perspicacity and discernment. Increasing one’s intellectual aptitude allows for more steps of a deduction to be inferred in fewer acts of conceiving, thereby helping preserve the certainty of a deduction. (shrink)

Wittgenstein had little to say directly on philosophy of history. But some pertinent remarks in _On Certainty_ have received little attention, apart from in Elizabeth Anscombe's short article on Hume and Julius Caesar. That article acknowledges its debt to _On Certainty,_ which responses to Anscombe have failed to recognise. Wittgenstein focuses in _On Certainty_ on apparently empirical propositions that seem to be certainties, but in fact form a rule-like framework for judging. I have called these _Moorean propositions_, and the (...) present article develops the suggestion that history as a discipline rests on them. The result is a qualification of empiricism in philosophy of history. (shrink)

I want to suggest a way of approaching On Certainty that treats what Wittgenstein is doing in the notebooks that make up this work as manifesting a kind philosophical practice that is broadly Pyrrhonian, at least on one reading of what this involves. Such a reading fits with the general philosophical quietism found in Wittgenstein’s work, particularly in his later writings, and is also supported by independent textual evidence that he was profoundly influenced by Pyrrhonian scepticism. Crucially, however, it (...) also helps to clarify the sense in which the Pyrrhonian sceptical techniques, and hence the kind of philosophical quietism that goes along with them, can have an essentially disquieting effect on the subject.

The volume uncovers the most pragmatic and pragmatist aspects of Ludwig Wittgenstein’s philosophy, particularly of On Certainty, through a comparison with the pragmatist tradition as expressed by Charles S. Peirce and William James. On Certainty is often described as 'pragmatic' in literature and this pragmatic aspect is said to characterize a new turn in its author’s thought. Yet, what is still missing is a study of what specifically are the features which make these writings 'sound like pragmatism', as (...) Wittgenstein himself put it (OC 422). The book therefore aims to verify if and to what extent it is possible to sustain that there is an objective convergence between his thought and pragmatism. In doing so, the volume also proposes a clarification of the main differences between Peirce’s and James’ vision of some key ideas of classical pragmatism like doubt and certainty, common sense, the pragmatic maxim, action. Among the achievements of the work are: an analysis of Wittgenstein’s first mention of pragmatism; some pieces of evidence in favour of the hypothesis that Wittgenstein did read some works by Peirce; a documented investigation on the relevance of Frank Ramsey for the development of Wittgenstein’s idea of pragmatism. The volume does not sustain the thesis that Wittgenstein was a pragmatist (nor the opposing thesis that he was not), but highlights the objective convergences and the divergences between his perspective and pragmatism through a balanced analysis running both on an exegetical and on a theoretical level.

In this paper, I propose a comparison between some widely accepted Quinian views and Ludwig Wittgenstein's remarks on the logical and the empirical in On Certainty. While Quine's perspective and Wittgenstein's aare not thorougly dissimilar (so that the question of which influence Wittgenstein's thought might have had on the thought of some contemporary philosopher like Quine is both interesting and relevant), there is at least one important difference between them. I submit that Wittgenstein's view on this crucial distinction are (...) more general but ultimately more plausible than the nowadays popular Quinian view. (shrink)

Wittgenstein's writing is notoriously obscure. And his epistemological views are not widely read and, as much as they are, they are not widely accepted. This dissertation is a defense of these views as published under the title of On Certainty. Given the obscurity of his writing and the variety of interpretations it lends itself to, in order to defend his position I spell out what I take Wittgenstein's position to consist in as well as what its aim is, namely (...) a dissolution rather than refutation of the skeptical position. My aim is to bring to the forefront Wittgenstein's views as a real and worthy alternative to widely read responses to skepticism. (shrink)

This work provides a thorough index of terms found in Ludwig Wittgenstein's On Certainty. The index includes not only every philosophical term found in Wittgenstein's text, but also many non-philosophical terms when they are used in highly charged philosophical contexts. In all, there are some 575 main entries. Moreover, a concerted effort is made to indicate in what connections a given term is used by adding subordinate qualifying phrases to the main entries. For crucial terms (e.g., 'know,' 'proposition,' 'doubt,' (...) etc.) the sub-entries indicating context are quite extensive. (shrink)

Ludwig Wittgenstein is arguably the most important philosopher of the twentieth century. In On Certainty he discusses central issues in epistemology, including the nature of knowledge and scepticism. The Routledge Philosophy Guidebook to Wittgenstein and On Certainty introduces and assesses: Wittgenstein's career and the background to his later philosophy the central ideas and text of On Certainty , including its responses to G.E. Moore and discussion of fundamental issues in the theory of knowledge Wittgenstein's continuing importance in (...) contemporary philosophy. This GuideBook is essential reading for all students of Wittgenstein, and for those studying epistemology and philosophy of language. On Certainty, Wittgenstein's final work, addresses a category of "world-picture" propositions discovered by G.E. Moore. These challenge Wittgenstein's enduring commitment to a well-defined category of empirical propositions, and help to generate a critique of scepticism. Developing Wittgenstein's view that scepticism is self-undermining, the Guidebook offers a combative yet therapeutic interpretation that locates On Certainty between the standpoints of Kant and Hume.
