This paper derives a mathematical expression giving the development of the probability of a scientific hypothesis with the number of confirming tests, as determined by Bayes's theorem, in a special case in which all the tests are "independent" of one another. The simple expression obtained shows clearly how the various factors influence the growth of the probability. The result is used to set a numerical lower bound on the probabilities representing the a priori beliefs of humans in generalizations that become (...) accepted. By making a comparison with the predictions of a "logical atomic" model in the case of physical laws, it is argued that humans have significant a priori "knowledge" in a weak sense. (shrink)

The following progress report views language acquisition as primarily the attempt to create processes that connect together in a fruitful way linguistic input and other activity. The representations made of linguistic input are thus those that are optimally effective in mediating such interconnections. An effective Language Acquisition Device should contain mechanisms specific to the task of creating the desired interconnection processes in the linguistic environment in which the language learner finds himself or herself. Analysis of this requirement gives clear indications (...) as to what these mechanisms may be. (shrink)

This chapter examines the developments that led from Wittgenstein’s early logical atomist view that all meaningful discourse can be analyzed into logically independent elementary propositions to his later philosophy. In 1929, Wittgenstein rejected logical atomism for a “logical holist” conception of language as composed of calculi, formal systems characterized by their constitutive rules. By the mid-1930s, he had rejected the model of a calculus, emphasizing that language is action within a social and natural context — more like a game than (...) a calculus — and that rule-governed behavior is dependent on a background of practices which cannot themselves be explicitly formulated as rules. The discussion of these central developments for the emergence of his later “practical holism” focuses on changes in his conception of the nature of measurement and the role of mind and mental processes in linguistic meaning.

An analysis of the sources of Wittgenstein’s picture theory — which include not only his moment of insight on reading a magazine story about the use of models in a traffic court, but also the work of Russell, Hertz, and Boltzmann — provides the basis for an exploration of Wittgenstein’s articulation of a pictorial conception of representation in his wartime notebooks and its crystallization in the Tractatus. A discussion of Wittgenstein’s later criticism of the picture theory and his notion of (...) a “philosophical picture” illustrates the fundamental reversal in his transition to his later conception of philosophy: instead of taking literal pictures as a guide to the nature of meaning, he came to regard philosophical theories as akin to expressing an aesthetic preference for a certain style of representation. Wittgenstein’s treatment of factual language in the picture theory is related to his Tractarian approach to logical form, and the role of the show/say distinction in his early conception of logic and language. Particular attention is given to the difficulties generated by the idea that the conditions for the possibility of a given domain of discourse cannot be described in language, but must be shown by the form of words in question.

This chapter argues that the ontology of the Tractatus is best understood as the consequence of Wittgenstein’s conception of logic and representation in general, and the postulate of the determinacy of sense in particular. Once it is recognized that Wittgenstein arrived at the idea of simple objects based on an abstract argument about the nature of complexes and analysis without providing any specific examples of such analyses, it is easy to see the need for caution in attributing any characteristics to (...) the objects over and above those demanded by Wittgenstein’s logicolinguistic commitments. Commentators have taken the Tractatus to be setting out a bewildering variety of highly specific views about the nature of objects. But the truth is that the book is so programmatic that its ontology can be elaborated in any number of ways. The final section of this chapter analyzes Wittgenstein’s treatment of the self in the Tractatus and his writing from the 1930s as a central example of the extreme tensions between the positivisistic doctrines stated in the Tractatus and the antipositivistic subtext it aims to convey or “show”: if the exoteric doctrine of the Tractatus is that there is no such thing as the subject of experience, the esoteric doctrine is that there is. This leads to a close reading of his proposal in the early 1930s that is considered a “subjectless” language as a way of clarifying the nature of experience, and his subsequent critique of the notions of the “metaphysical self” and the “visual world”. He had transmuted the difference between the first person and third person modes of speech into differences between two worlds and then had tried to put them back together again. (shrink)

Unlike most books on Wittgenstein, Wittgenstein on Mind and Language begins from the initial articulation of his thoughts in his first drafts, conversations, and lectures, and attends closely to the process of revision that led to the Tractatus and Philosophical Investigations. This introductory chapter provides information about the nature of the Wittgenstein papers, summarizes the rationale for reading his work in this way, and outlines the reading of the development of Wittgenstein’s philosophy that this approach yields. This discussion on the (...) development of Wittgenstein’s thought emphasizes the role of his changing conception of the nature of experience and its relationship to the world, the closely related problem of the relationship between ordinary language and its analysis, his later conception of the role of analogies in generating — and dissolving — philosophical problems, the parallels with psychoanalysis, and the variety of philosophical methods employed in his later philosophical writing. There is also an overview of a central theme of the book as a whole: the contrast Wittgenstein drew between “ordinary” and “philosophical” ways of looking at things when he wrote the Tractatus, and how that contrast was transformed in his subsequent writing, focusing on his contrast between “primary” and “secondary” worlds and his notion of a “phenomenological language”.

In 1929, Wittgenstein made use of river imagery to convey the supposedly inexpressible thesis that all is in flux. However, he rejects this extreme thesis in manuscripts from the early 1930s and drafts of the Philosophical Investigations, affirming that one can step twice into the same river. His later discussion of the “stream of life” involves a return, in certain respects, to the river analogy, albeit in a very different key. Examining Wittgenstein’s changing use of this image casts light on (...) the continuities and discontinuities in the development of his philosophy. Wittgenstein’s argument that a private definition is impossible because ostension always depends on a “technique of use”, and his rejection of a positive theory of mind is clarified by examining some unusually explicit notes for a public lecture on private language. This material shows how the treatment of training and practice in the opening sections of the Philosophical Investigations is the basis for the subsequent discussion of both rule-following and privacy.

A key philosophical feature of Peter Jackson’s film interpretation of J.R.R. Tolkien’s The Lord of the Rings is its use of fantasy to inspire a “recovery” of the actual or, in other words, a reawakening to the beauty of nature and the many possible ways of living in healthier ecological relation to the world. Though none of these ways is perfectly achieved, this pluralistic view is demonstrated in the various lifeways of Hobbits, Elves, Men, and Ents. All of the positive (...) relationships embodied in the films—to trees, mountains, horses, and vegetable gardens—involve loving care and attention, receiving nourishment and livelihood without instrumentalization, or reducing nature to mere resource. The films also vividly display a variety of ugly and destructive ways of using the land to accrue power and wealth. These noxious ways, specifically because they actively destroy the lands that they use, always need more. They will thus eventually annihilate the beautiful ways of being if they are not actively resisted. Some of those who would rather be tending their own trees, gardens, or horses or even wandering in the wild forests must therefore turn their attention to struggle and resistance instead. This is a struggle full of grief, and at times even verging on despair, but it is marked by the refusal to give up hope. Indeed, what Jackson and Tolkien have to say about hope is as important in responding to the ecological crisis as anything they have to say about nature, inasmuch as they help to remind us that even in our own times, “there is still hope.”.

Drawing on ten years of research on the unpublished Wittgenstein papers, Stern investigates what motivated Wittgenstein's philosophical writing and casts new light on the Tractatus and Philosophical Investigations. The book is an exposition of Wittgenstein's early conception of the nature of representation and how his later revision and criticism of that work led to a radically different way of looking at mind and language. It also explains how the unpublished manuscripts and typescripts were put together and why they often provide (...) better evidence of the development of his ideas than can be found in his published writing. In doing so, the book traces the development of a number of central themes in Wittgenstein's philosophy, including his conception of philosophical method, the picture theory of meaning, the limits of language, the application of language to experience, his treatment of private language, and what he called the "flow of life." Arguing that Wittgenstein's views are often much more simple (and more radical) than we have been led to believe, Wittgenstein on Mind and Language provides an overview of the development of Wittgenstein's philosophy and brings to light aspects of his philosophy that have been almost universally neglected.

In this new introduction to a classic philosophical text, David Stern examines Wittgenstein's Philosophical Investigations. He gives particular attention to both the arguments of the Investigations and the way in which the work is written, and especially to the role of dialogue in the book. While he concentrates on helping the reader to arrive at his or her own interpretation of the primary text, he also provides guidance to the unusually wide range of existing interpretations, and to the reasons (...) why the Investigations have inspired such a diversity of readings. Following closely the text of the Investigations and meant to be read alongside it, this survey is accessible to readers with no previous background in philosophy. It is well-suited to university-level courses on Wittgenstein, but can also be read with profit by students in other disciplines. (shrink)

This edition of G. E. Moore's notes taken at Wittgenstein's seminal Cambridge lectures in the early 1930s provides, for the first time, an almost verbatim record of those classes. The presentation of the notes is both accessible and faithful to their original manuscripts, and a comprehensive introduction and synoptic table of contents provide the reader with essential contextual information and summaries of the topics in each lecture. The lectures form an excellent introduction to Wittgenstein's middle-period thought, covering a broad range (...) of philosophical topics, ranging from core questions in the philosophy of language, mind, logic, and mathematics, to illuminating discussions of subjects on which Wittgenstein says very little elsewhere, including ethics, religion, aesthetics, psychoanalysis, and anthropology. The volume also includes a 1932 essay by Moore critiquing Wittgenstein's conception of grammar, together with Wittgenstein's response. A companion website offers access to images of the entire set of source manuscripts. (shrink)

Originally conceived as a forty-page conclusion to Hacker’s twenty years of work on the monumental four-volume Analytical Commentary on the Philosophical Investigations, this book “rapidly assumed a life of its own”. A major contribution to the history of analytic philosophy, this substantial volume delivers even more than the title promises. The eight chapters are best approached as a six-chapter book, itself some 220 pages long, on Wittgenstein’s contribution to twentieth-century philosophy, followed by a two-chapter, 120-page epilogue about how and why (...) his influence has waned. The first six chapters provide an encyclopedic summary of the fruits of Hacker’s research on Wittgenstein’s writing, an immensely learned account of British philosophy from the turn of the century to the 1970s, and a detailed account of Wittgenstein’s reception by Oxford, Cambridge, and the Vienna Circle. The book’s closing chapters, “Post-positivism in the United States and Quine’s Apostasy” and “The Decline of Analytic Philosophy,” polemically argue that Quine’s philosophy, and the post-Quinean naturalism prevalent in Anglo-American philosophy today, amount to such a decisive break with the analytic tradition, as Hacker conceives of it, that they should not be counted as “analytic.”.

The alliance of discursivity with neurosis on the one hand, and an exploration of new conditions of discourse on the other, conditions now self consciously denoted as 'West', gives notice of a certain disillusionment I feel with my culturally received, monotheistic valourization of the power of 'word-ing', and my sense that the problem is not discourse per se, but the way my understanding of it is, or has been, too stuck within its own cultural self enclosure, within the compound of (...) its own cultural grammar, one might say. In taking up these issues within the context of a conference convened to consider "Fragmentation and the Desire for Order/Unity" play off each other relationally, or symbiotically but how so inevitably and incidentally in the West that play-off has a neurotic tail-chasing character that is inspired precisely by Desire. My remarks, therefore, about the possibilities of new conditions of discourse for the West, turn most profoundly on a problematizing of Desire itself. (shrink)

One of the great contributions of postmodern thinkers like Michel Foucault and Jacques Derrida to the human sciences generally, in which Education is situated, has been the concept of "discourse." To call a particular way of thinking and acting a discourse is to reference the way meaning is achieved amongst actors by a mutual agreement, direct or tacit, about key terms and actions. A discourse is a kind of self-enclosed semantic and practical universe within which people operate "as if" everyone (...) knew what everyone else is talking about. (shrink)

Examining the significance of Kant's account of "rational faith," this study argues that he profoundly revises his account of the human will and the moral philosophy of it in his later religious writings.

Drawing on recent work on the nature of the numbering system of the _Tractatus_ and Wittgenstein’s use of that system in his composition of the _Prototractatus_, the paper sets out the rationale for the online tool called__ __ The University of Iowa Tractatus Map. The map consists of a website with a front page that links to two separate subway-style maps of the hypertextual numbering system Wittgenstein used in his _Tractatus_. One map displays the structure of the published _Tractatus_; the (...) other lays out the structure of the _Prototractatus_. The site makes available the full text of the German and the two canonical English translations.__ __While we envisage the map as a tool that we would like a wide variety of readers to find helpful, we argue that our website amounts to a radically new edition of Wittgenstein’s early masterpiece, with far-reaching implications for the interpretation of that text. In particular, we claim that our visually compelling presentation of the book’s overall structure delivers on Wittgenstein’s cryptic claim in a letter to his publisher that it is the numbers that “make the book surveyable and clear”.

Semiotic objections to markets urge us not to place a good on the market because of the message that doing so would send. Brennan and Jaworski reject them on the grounds that either the contingent semiotics of a market can be changed or the weakness of semiotic reasons allows them to be ignored. The scope of their argument neglects the impure semiotic objections that claim that the message a market sends causes, constitutes, or involves a nonsemiotic wrong. These are the (...) most compelling class of semiotic objections and are the kind actually advanced in the literature. Rather than focusing on the necessity or contingency of a market's semiotics, we should instead attend to a semiotic objection's most important feature: its purity or impurity. (shrink)

The current coronavirus pandemic presents the greatest healthcare crisis in living memory. Hospitals across the world have faced unprecedented pressure. In the face of this tidal wave of demand for limited healthcare resources, how are clinicians to identify patients most likely to benefit? Should age or frailty be discriminators? This paper seeks to analyse the current evidence-base, seeking a nuanced approach to pandemic decision-making, such as admission to critical care.

The "standard account" of Wittgenstein’s relations with the Vienna Circle is that the early Wittgenstein was a principal source and inspiration for the Circle’s positivistic and scientific philosophy, while the later Wittgenstein was deeply opposed to the logical empiricist project of articulating a "scientific conception of the world." However, this telegraphic summary is at best only half-true and at worst deeply misleading. For it prevents us appreciating the fluidity and protean character of their philosophical dialogue. In retrospectively attributing clear-cut positions (...) to Wittgenstein and his interlocutors, it is very easy to read back our current understanding of familiar distinctions into a time when those terms were used in a much more open-ended way. The paper aims to to provide a broader perspective on this debate, starting from the protagonists’ understanding of their respective positions. Too often, the programmatic statements about the nature of their work that are repeated in manifestoes, introductions, and elementary textbooks have occupied center stage in the subsequent secondary literature. Consequently, I focus on a detailed examination of a turning point in their relationship. That turning point is Wittgenstein's charge, in the summer of 1932, that a recently published paper of Carnap's, "Physicalistic Language as the Universal Language of Science", made such extensive and unacknowledged use of Wittgenstein's own ideas that Wittgenstein would, as he put it in a letter to Schlick, "soon be in a situation where my own work shall be considered merely as a reheated version or plagiarism of Carnap’s." While the leading parties in this dispute shared a basic commitment to the primacy of physicalistic language, and the view that all significant languages are translatable, there was a remarkable lack of mutual understanding between them, and deep disagreement about the nature of the doctrines they disputed. Three quarters of a century later, we are so much more conscious of the differences that separated them than the points on which they agreed that it takes an effort of historical reconstruction to appreciate why Wittgenstein once feared that his own work would be regarded as a pale shadow of Carnap’s.

Wittgenstein's principal works, the Tractatus Logico‐Philosophicus and Philosophical Investigations, are each written in such strikingly unconventional ways that it takes considerable effort to translate them into conventional philosophical writing. The most important aspect of Wittgenstein's style for an understanding of his philosophy is his use of multiple voices, and the way he forces his reader to engage with those voices in order to understand him. This chapter provides an outline of the leading macro‐level answers to the question which of Wittgenstein's (...) writings set out his philosophy, and which set out views he rejected. Wittgenstein's method of composition, revision, and rearrangement, leads from the remarks written down in his wartime notebooks, to a manuscript containing several stages of construction of the Prototractatus, and from there to the polished typescript of the Tractatus. The chapter illustrates how to interpret Wittgenstein's remarks without taking a position on questions about texts and style, voice and authorship. (shrink)

Wittgenstein's 'middle period' is often seen as a transitional phase connecting his better-known early and later philosophies. The fifteen essays in this volume focus both on the distinctive character of his teaching and writing in the 1930s, and on its pivotal importance for an understanding of his philosophy as a whole. They offer wide-ranging perspectives on the central issue of how best to identify changes and continuities in his philosophy during those years, as well as on particular topics in the (...) philosophy of mind, religion, ethics, aesthetics, and the philosophy of mathematics. The volume will be valuable for all who are interested in this formative period of Wittgenstein's development. (shrink)

There are some things money literally cannot buy. Invariably transformable goods are such things because when they are exchanged for money, they become something else. These goods are destroyed rather than transferred in monetary exchanges. They mark out an impassable limit beyond which money and the market cannot reach. They cannot be for sale, in the strongest and most literal sense. Variably transformable goods are similar. They can be destroyed when offered or exchanged for money, but they differ in their (...) ability to sometimes emerge from financial transactions intact. -/- Analyzing transformable goods reveals informative and surprising results. Like other goods and commodities, they are agent relative, defined by the way particular agents value them. Inside the same transaction, a good could be transformable for one agent and not another, depending on how and what these agents value in the transaction. Applying this conceptual framework can reveal otherwise obscure facets of existing and future debates about the ethics and limits of markets. To demonstrate this, the framework is here applied to Richard Titmuss’s arguments about markets in blood, clarifying and illuminating some of his most confusing claims. Applying this framework to other debates may reveal even more striking results. (shrink)

Whose values should count – those of patients or the general public – when adopting the quality-adjusted life year framework for healthcare decision making is a long-standing debate. Specific disciplines, such as economics, are not wedded to a particular side of the debate, and arguments for and against the use of patient values have been discussed at length in the literature. In 2012, Sinclair proposed an approach, grounded within patient preference theory, which sought to avoid a perceived unfair discrimination against (...) people with disabilities when using values from the general public. Key assumptions about general public values that beget this line of thinking were that ‘disabled states always tally with lower quality of life’, and the use of standardised instruments means that ‘you are forced into a fixed view of disability as a lower value state’. Drawing on recent contributions to the health economics literature, we contend that such assumptions are not inherent to the incorporation of general public values for the estimation of QALYs. In practice, whether health states of people with disabilities are of ‘lower value’ is, to some extent, a reflection of the health state descriptions that members of the public are asked to value.

Jerome Wakefield has argued that a disorder is a harmful dysfunction. This paper develops how Wakefield should construe harmful in his harmful dysfunction analysis. Recently, Neil Feit has argued that classic puzzles involved in analyzing harm render Wakefield’s HDA better off without harm as a necessary condition. Whether or not one conceives of harm as comparative or non-comparative, the concern is that the HDA forces people to classify as mere dysfunction what they know to be a disorder. For instance, one (...) can conceive of cases where simultaneous disorders prevent each other from being, in any traditional sense, actually harmful; in such cases, according to the HDA, neither would be a disorder. I argue that the sense of harm that Wakefield should employ in the HDA is dispositional, similar to the sense of harm used when describing a vile of poison: “Be careful! That’s poison. It’s harmful.” I call this harm in the damage sense. Using this sense of harm enables the HDA to avoid Feit’s arguments, and thus it should be preferred to other senses when analyzing harmful dysfunction. (shrink)

I argue that the numbering system of the Tractatus lets us see how it was constructed, in two closely related senses of that term. First, it tells us a great deal about the genesis of the book, for the numbering system was used to assemble and rearrange a series of drafts, as recorded in MS 104. Second, it helps us understand the structure of the published book, as cryptically summarized in the opening footnote. I also discuss an unpublished letter from (...) Anscombe to von Wright from 1948 which contains the very first sketch of a tree-structured reading, and what I believe is Stenius’s response to Anscombe’s proposal. The paper critically evaluates previous work on tree-structured readings and contends that we need to read the Tractatus in both the number order used in the published book and the tree order that Wittgenstein used to draft it. It also considers some of the main ways of turning this complex branching structure into a linear, printed text, and so serves as an introduction to the three tree-structured editions of the Tractatus that accompany this paper (the German text, and the translations by Ogden/Ramsey and Pears & McGuinness).

In the debates concerning the ethics of human enhancement through biological or technological modifications, there have been several appeals to the concept of human dignity, both by those favouring such enhancement and by those opposing it. The result is the phenomenon of ‘dignity talk', where opposing sides both appeal to the concept of human dignity to ground their arguments resulting in a moral impasse. This article examines the use of the concept of human dignity in the enhancement debates and reveals (...) that the problem of dignity talk arises because proponents of various positions tend to ground human dignity in different features of the human individual. These features include species-membership, possession of a particular capacity, a sense of self-worth, and moral behaviour. The article proposes a solution to this problem by appealing to another feature of human beings, namely their being-in-relationship-over-time. Doing so enables us to understand dignity as a concept that affirms the worth of human individuals as complex, multidimensional wholes, rather than as isolated features. Consequently, the concept of human dignity can serve both a descriptive and a normative function in the enhancement debates. At a descriptive level, asking what advocates of a position mean when they refer to human dignity will reveal what aspects of being human they deem to be most valuable. The debate can then focus on these values. The normative function, although it cannot proscribe or prescribe all enhancement, approves only those enhancements that contribute to the flourishing of human individuals as multidimensional wholes.

Locke’s property rights are now usually understood to be both fundamental and strictly negative. Fundamental because they are thought to be basic constraints on what we may do, unconstrained by anything deeper. Negative because they are thought to only protect a property holder against the claims of others. Here, I argue that this widespread interpretation is mistaken. For Locke, property rights are constrained by the deeper ‘fundamental law of nature,’ which involves positive obligations to those in need and confines the (...) right to excess property within circumstances where it is not needed to preserve human life.

Wittgenstein’s writings and lectures during the first half of the 1930s play a crucial role in any interpretation of the relationship between the Tractatus and the Philosophical Investigations . G. E. Moore’s notes of Wittgenstein’s Cambridge lectures, 1930-1933, offer us a remarkably careful and conscientious record of what Wittgenstein said at the time, and are much more detailed and reliable than previously published notes from those lectures. The co-authors are currently editing these notes of Wittgenstein’s lectures for a book to (...) be published by Cambridge University Press. We describe the materials that make up Moore’s notes, explain their unique value, review the principal editorial challenges that these materials present, and provide a brief outline of our editorial project.

Ruth Macklin argued that dignity is nothing more than respect for persons or their autonomy. During the COVID-19 pandemic, difficult decisions are being made about the allocation of scarce resources. Respect for autonomy cannot justify rationing decisions. Justice can be invoked to justify rationing. However, this leaves an uncomfortable tension between the principles. Dignity is not a useless concept because it is able to account for why we respect autonomy and for why it can be legitimate to override autonomy in (...) times of critical care resource shortages. Dignity affirms the worth of the human individual as a meaning-making embodied subject, who is always in relationship to others, the world, time, and transcendence, and who realizes their dignity through their moral behaviour. Such an understanding means people should be helped to make morally right decisions about their own treatment, which may include forgoing potentially beneficial treatment for the good of others. Respect for dignity does not require fulfilling the morally wrong choices of one who insists on treatment at the expense of others. Dignity also protects the discretion of clinicians to make decisions appropriate to their competence by prohibiting the application of broad-based criteria such as age. (shrink)
