I defend the view that aspect-perception – seeing as a duck, or a face as courageous – typically involves concept-application. Seemingly obvious, this is contested by Avner Baz: ‘aspects may not aptly be identified with, or in terms of, empirical concepts […]’ – In opposition, I claim that they may. Indeed, in many cases there is no other way to identify aspects.I review the development in Baz’s view, from his early criticism of Stephen Mulhall, to his recent recruitment of the (...) discussion about aspects to criticize John McDowell’s conceptualism, and his claim: ‘the dawning of Wittgensteinian aspects reveals our power to perceive unity and sense that are not aptly thought of as conceptual’.I accept many of Baz’s claims against Mulhall and McDowell. However, his arguments go too far. Aspect-perception, I argue, typically involves a special kind of application of concepts. Denying that is denying much of what is important and of interest in the phenomena of aspect. The world revealed in aspect-perception is not the conceptualized world of science; but it is also not the pre-conceptualized ‘phenomenal’ world which, according to Baz, we normally have in perception, and which he wants to bring into view.

According to a widespread view in metaphysics and philosophy of science, all explanations involve relations of ontic dependence between the items appearing in the explanandum and the items appearing in the explanans. I argue that a family of mathematical cases, which I call “viewing-as explanations”, are incompatible with the Dependence Thesis. These cases, I claim, feature genuine explanations that aren’t supported by ontic dependence relations. Hence the thesis isn’t true in general. The first part of the paper defends this claim (...) and discusses its significance. The second part of the paper considers whether viewing-as explanations occur in the empirical sciences, focusing on the case of so-called fictional models. It’s sometimes suggested that fictional models can be explanatory even though they fail to represent actual worldly dependence relations. Whether or not such models explain, I suggest, depends on whether we think scientific explanations necessarily give information relevant to intervention and control. Finally, I argue that counterfactual approaches to explanation also have trouble accommodating viewing-as cases. (shrink)

Broadly speaking, language is part of a social activity in both Wittgenstein and Xunzi 荀子, and for both clarification of language is central to their philosophical projects; the goal of this article is to explore the extent of resonance and discord that may be found when comparing these two philosophers. While for Xunzi, the rectification of names (zhengming 正名) is anchored in a regard for establishing, propagating, and/or restoring a harmonious social system, perspicuity is for Wittgenstein represented as a philosophical (...) end in itself. The article ventures study in particular the themes of perspicuity and aspect-perception in Wittgenstein together with the topics of correcting names and the cultivation of the heart-mind (xin 心) in the Xunzi. The aspiration of this project is to gain an overview of the role(s) of clarification projects in different philosophical traditions, all while not overlooking the different historical contexts and philosophical ends of these two philosophers.

This essay accounts for the notion of _Lebensform_ by assigning it a _logical _role in Wittgenstein’s later philosophy. Wittgenstein’s additions of the notion to his manuscripts of the _PI_ occurred during the initial drafting of the book 1936-7, after he abandoned his effort to revise _The Brown Book_. It is argued that this constituted a substantive step forward in his attitude toward the notion of simplicity as it figures within the notion of logical analysis. Next, a reconstruction of his later (...) remarks on _Lebensformen_ is offered which factors in his reading of Alan Turing’s “On computable numbers, with an application to the _Entscheidungsproblem_“, as well as his discussions with Turing 1937-1939. An interpretation of the five occurrences of _Lebensform_ in the PI is then given in terms of a logical “regression” to _Lebensform_ as a fundamental notion. This regression characterizes Wittgenstein’s mature answer to the question, “What is the nature of the logical?”. (shrink)

In ‘Aesthetics Problems of Modern Philosophy’ Stanley Cavell proposes, first, that Kant's characterization of judgments of beauty may be read as a Wittgensteinian grammatical characterization, and, second, that the philosophical appeal to ‘what we say and mean’ partakes of the grammar of judgment of beauty. I argue first that the expression of the dawning of an aspect partakes of the grammar of judgments of beauty as characterized by Kant, and may also be seen—on a prevailing way of thinking about concepts (...) and how they relate to their instances—to have the same kind of significance that judgments of beauty have according to Kant. And then I argue that there are good reasons for being suspicious of the prevailing conception of concepts, and therefore good reasons for being suspicious of the proposed understanding of the significance of aspect perception—an understanding that has attracted many readers of Wittgenstein's remarks on aspects. This leads me to suggest that it is actually the philosophical appeal to ordinary language that has the kind of significance that the Kantian picture attributes to judgments of beauty and to the seeing of aspects. In this way, I offer a way to vindicate Cavell's second proposal. (shrink)

In her Introduction to Wittgenstein’s Tractatus , Elizabeth Anscombe took it to be a fault of the Tractatus that it excluded the statement “‘Someone’ is not the name of someone”, which she took to be obviously true. It is not a bipolar proposition, and its negation, she said, peters out into nothingness. I examine the question whether she is right that the Tractatus excludes such propositions, and I consider her example in relation to other propositions which, arguably at least, have (...) no intelligible negation. In considering the particular case of Frege’s response to Benno Kerry about the concept ‘horse’, I try to develop an account of the place in Wittgenstein’s philosophy for certain sorts of proposition which do not have an intelligible negation.

Additional theorizing about mathematical practice is needed in order to ground appeals to truly useful notions of the virtues in mathematics. This paper aims to contribute to this theorizing, first, by characterizing mathematical practice as being epistemic and “objectual” in the sense of Knorr Cetina The practice turn in contemporary theory, Routledge, London, 2001). Then, it elaborates a MacIntyrean framework for extracting conceptions of the virtues related to mathematical practice so understood. Finally, it makes the case that Wittgenstein’s methodology for (...) examining mathematics and its practice is the most appropriate one to use for the actual investigation of mathematical practice within this MacIntyrean framework. At each stage of thinking through mathematical practice by these means, places where new virtue-theoretic questions are opened up for investigation are noted and briefly explored. (shrink)

L'idée de « progrès » en philosophie, ancrée dans la devise des Recherches Philosophiques, est à la fois grammaticale et autobiographique. Où se trouvait le progrès de Wittgenstein dans les années qui avaient suivi le Tractatus? Quelles leçons tirer de son parcours? Pour répondre à la question, il faut repenser la manière dont la grammaire du « progrès » doit être pesée et mesurée en philosophie. Nous nous appuyons sur l'essai de Jacques Bouveresse « Les ténèbres de notre temps (1991)» (...) et l'idée de Stanley Cavell selon laquelle la pratique philosophique de Wittgenstein dans le Tractatus et les Recherches Philosophiques s'appuient partout sur le fait de voir à travers les réalités les possibilités, traiter la « forme » comme une possibilité de la structure. Cela permet de retracer le destin de tournants de pensée apparaissant déjà dans le Tractatus : variations sur des lignes de pensée que Wittgenstein reprendra plus tard et qu’il réorchestrera d'une nouvelle manière.

Dans son Introduction au Tractatus de Wittgenstein, Elizabeth Anscombe considérait que le livre avait le défaut d’exclure la proposition « “Quelqu’un” n’est pas le nom de quelqu’un » qu’elle considérait comme évidemment vraie. Ce n’est pas une proposition bipolaire et sa négation n’est pas intelligible. J’examine la question de savoir si elle a raison de dire que le Tractatu s exclut de telles propositions, et je considère son exemple en relation avec d’autres propositions qui, du moins en théorie, n’ont pas (...) de négation intelligible. En considérant le cas particulier de la réponse de Frege à Benno Kerry sur le concept de ‘cheval’, j’essaie de développer une approche de la place que donne la philosophie de Wittgenstein à certains types de proposition qui n’ont pas de négation intelligible.

This article characterizes aspect-perception as a distinct form of judgment in Kant's sense: a distinct way in which the mind contacts world and applies concepts. First, aspect-perception involves a mode of thinking about things apart from any established routine of conceptualizing them. It is thus a form of concept application that is essentially reflection about language. Second, this mode of reflection has an experiential, sometimes perceptual, element: in aspect-perception, that is, we experience meanings—bodies of norms. Third, aspect-perception can be “preparatory”: (...) it may help us to decide what linguistic norms to develop and how to conceptualize—make the world thinkable. Fourth, the article discusses the forms of justification for which aspect-perception allows—the necessity and normativity involved in employing this form of judgment. (shrink)

I argue that the typical Wittgensteinian method of philosophical investigation cannot help elucidate the grammar of aspect-seeing. In the typical Wittgensteinian method, we examine meaning in use: We practice language, and note the logical ramifications. I argue that the effectiveness of this method is hindered in the case of aspect-seeing by the fact that aspect-seeing involves an aberrant activity of seeing: Whereas it is normally nonsense to say that we choose what to see (decide to see the White House red, (...) for instance), it is possible to see aspects at will—e.g. to decide to see Jastrow’s duck-rabbit as a duck. I suggest an alternative method of investigation, one that reflects on language from a disengaged standpoint: a method that allows us to entertain a form of conceptualization of an object but does not commit us to adopting that way—namely, that does not involve us in a use of the object according to the norms that govern that conceptualization. This method, I argue, fits the s ubject matter of aspect-perception, since aspect-perception itself involves such a disengaged form of reflection. (shrink)

Une théorie de la science qui permette une « étude systématique des formes » est l’ἐπιστήμη ζητοῦμένη de Cavaillès : ce dernier ne la trouve ni dans l’analytique kantienne, ni dans la théorie de la science de Bolzano ; pas plus que chez Frege, Carnap ou Tarski ; et ni dans la théorie de la démonstration, ni dans la mathesis husserlienne. Cet article défend l’idée qu’il aurait pu la trouver, ou du moins s’en approcher, s’il avait accordé davantage d’attention à (...) une figure de la logique qu’il a délaissée : celle qu’incarnent Russell et son héritier Wittgenstein. L’analyse de la notion même de forme, que celle-ci désigne un complexe symbolique, une structure mathématique ou un schéma démonstratif, y aurait également gagné. (shrink)
