This short book comprises “four largely self-contained studies … unified by a common interpretive approach”, the “investigation of the historical development of … Wittgenstein’s early philosophy”. Proops applies this historical approach to Wittgenstein’s conception of logic, his critique of “logical assertion,” his “picture theory” of language, and his discussion of the justification of deduction. He endeavors to “bring out how Wittgenstein develops his views … as foils to the positions developed by Frege and Russell”, arguing that “it is not Frege but Russell whose work provides the most important background for … the Tractatus”.

Thomas Ricketts has developed a powerful interpretation of Frege on judgment, truth and logic. Recently, Ricketts has modified his reading, holding that judgment is an act of knowledge-acquisition; this rules out incorrect judgment. I argue that Ricketts goes too far here. I criticize the textual basis for Ricketts's new view, and show that the interpretive problems which led him to this change can be met without such extreme measures. Thus, I defend Ricketts' earlier view against his own later modification. Along the way I discuss Kant and Brentano on judgment, and I explore Fregean argument concerning the objectivity of truth

George Wilson has recently defended Kripke's well-known interpretation of Wittgenstein against the criticisms of John McDowell. Wilson claims that these criticisms rest on misunderstandings of Kripke and that, when correctly understood, Kripke's interpretation stands up to them well. In particular, Wilson defends Kripke's Wittgenstein against the charge of "non-factualism" about meaning. However, Wilson has not appreciated the full significance of McDowell's criticism. I use a brief exploration of Kripke's analogy between Wittgenstein and Hume to put this significance in sharp relief. It emerges that McDowell's response to Kripke's Wittgenstein account of meaning is in important respects analogous to Kant's response to Hume's account of causality, particularly Kant's complaint that Hume reduced the objective necessity of the causal nexus to a merely subjective necessity. In the same way Kripke's Wittgenstein reduces the objective normative force of meanings to a "quasi-subjective," community-relative status.

My title1 is taken from one of the most obscure, and most discussed, sections of an already obscure and much discussed work, the discussion of the self, the world, and solipsism in sections 5.6-5.641 of Ludwig Wittgenstein’s Tractatus Logico- Philosophicus.2 Wittgenstein writes: 5.6 The limits of my language mean the limits of my world. 5.61 Logic fills the world: the limits of the world are also its limits. We cannot therefore say in logic: This and this there is in the world, that there is not. For that would apparently presuppose that we exclude certain possibilities, and this cannot be the case since otherwise logic must get outside the limits of the world: that is

Frege’s distinction between sense (Sinn) and meaning (Bedeutung) is his most influential contribution to philosophy, however central it was to his own projects, and however he may have conceived its importance. Philosophers of language influenced by, or reacting against the distinction, and historians of philosophy commenting on it, have all contributed to the voluminous literature surrounding it.1 Nonetheless in this essay I hope to shed new light on the distinction by considering it in the context of the development of Frege’s thought, and connecting it more intimately than is usually done with Frege’s interests in logic, especially his views on judgment, truth and inference, which were central to his own projects as he conceived them

Gilbert Ryle’s distinction between knowledge-how and knowledge-that emerged from his criticism of the “intellectualist legend” that to do something intelligently is “to do a bit of theory and then to do a bit of practice,” and became a philosophical commonplace in the second half of the last century. In this century Jason Stanley has attacked Ryle’s distinction, arguing that “knowing-how is a species of knowing-that,” and accusing Ryle of setting up a straw man in his critique of “intellectualism.” Examining the use of the terms “intellectualism” and “anti-intellectualism” in the first half of the 20th century, in a wide-ranging debate in the social sciences as well as in philosophy, I show that Ryle was not criticizing a straw man, but a live historical position. In the context of this controversy, Ryle’s position represents a third way between “intellectualism” and “anti-intellectualism,” an option that has largely gone missing in the 21st century discussion. This argument illustrates how history can inform the history of philosophy, and how the history of philosophy can inform contemporary philosophical inquiry.

Last spring, as I was beginning a graduate seminar on Frege, I received a complimentary copy of this new translation of his masterwork, The Foundations of Arithmetic . I had ordered Austin's famous translation, well-loved for the beauty of its English and the clarity with which it presents Frege's overall argument, but known to be less than literal, and to sometimes supplement translation with interpretation. I was intrigued by Dale Jacquette's promise "to combine literal accuracy and readability for beginning students and professional scholars alike," and to improve on Austin where the latter "does not always faithfully represent or seem to perfectly understand certain of Frege's German idioms." (v) Such a translation, complete with index, critical introduction, and commentary, and at a bargain price, seemed worthy of my students' attention. So, I mentioned to the class that this book might be worth looking into

Gilbert Ryle's distinction between knowledge-how and knowledge-that faces a significant challenge: accounting for the unity of knowledge. Jason Stanley, an ‘intellectualist’ opponent of Ryle's, brings out this problem by arguing that Ryleans must treat ‘know’ as an ambiguous word and must distinguish knowledge proper from knowledge-how, which is ‘knowledge’ only so-called. I develop the challenge and show that underlying Ryle's distinction is a unified vision of knowledge as ‘a capacity to get things right’, covering both knowledge-how and knowledge-that. I show how Ryle specifies the general notion into knowledge-how and knowledge-that and discuss the mutual interdependence exhibited by the two forms of knowledge. Ryle's positive view of knowledge, properly understood, emerges as an important, neglected, alternative which should be brought back into the ongoing conversation about practical and theoretical knowledge.

Gyula begins with a contrast between contemporary scare-quotes essentialism and Aristotelian full-blooded essentialism. The former is a semantic thesis couched in the vocabulary of possible-worlds semantics, holding that some terms are rigid designators, while the latter is a metaphysical thesis, couched in a more ancient vocabulary, holding that things have essences. Gyula argues that the more traditional metaphysical framework deserves reconsideration, both because it can help us with problems arising from the contemporary approach, and because it possesses greater expressive power than the contemporary approach. He presents a fragmentary formal semantics for the traditional approach, and argues that this semantics enables us to see how the problems of contemporary essentialism can be avoided while at the same time other properly metaphysical issues, which are unapproachable from within the contemporary model due to its expressive weakness, become available for investigation. The semantics that he presents seems intended to establish the intelligibility of the traditional vocabulary, and so of the thesis of Aristotelian essentialism which is couched in it. Gyula then argues that this thesis is in fact true, using the vocabulary which the semantics has rendered legitimate

  Ted A. Warfield has recently employed modal logic to argue that compatibilism in the free-will/determinism debate entails the rejection of intuitively valid inferences. I show that Warfield's argument fails. A parallel argument leads to the false conclusion that the mere possibility of determinism, together with the necessary existence of any contingent propositions, entails the rejection of intuitively valid inferences. The error in both arguments involves a crucial equivocation, which can be revealed by replacing modal operators with explicit quantifiers over possible worlds. I conclude that the modal-logical apparatus used by Warfield obscures rather than clarifies, and distracts from the real philosophical issues involved in the metaphysical debate. These issues cannot be settled by logic alone

In "What is History For?," Scott Soames responds to criticisms of his treatment of Russell's logic in volume 1 of his "Philosophical Analysis in the Twentieth Century." This note rebuts two of Soames's replies, showing that a first-order presentation of Russell's logic does not fit the argument of the "Introduction to Mathematical Philosophy," and that Soames's contextual definition of classes does not match Russell's contextual definition of classes. In consequence, Soames's presentation of Russell's logic misrepresents what Russell took to be its technical achievement and its philosophical significance.

In work culminating in Know How (2009), Jason Stanley argues, against Gilbert Ryle, that knowledge-how is a species of knowledge-that. In How Propaganda Works (2015), Stanley portrays this work as undermining a “flawed ideology” supporting elitist valuations of intellectual work and workers. However, the link between Stanley’s two philosophical projects is weak. Ryle’s distinction between knowledge-how and knowledge-that lacks the political consequences foreseen by Stanley. Versions of “intellectualism” have as much potential to align with hierarchical political systems as do versions of “anti-intellectualism.” Consequently, the debate about knowledge-how and knowledge-that comes apart from Stanley’s more recent concerns about flawed ideologies.En un trabajo que encuentra su culminación en Know How (2009), Jason Stanely argumenta, en contra de Gilbert Ryle, que el saber-cómo es una especie del saber-qué. En How Propaganda Works (2015), Stanley presenta su trabajo como debilitador de una “falsa ideología” que respalda valoraciones elitistas del trabajo intelectual y los trabajadores intelectuales. Sin embargo, la conexión entre los dos proyectos filosóficos de Stanley es débil. La distinción de Ryle entre saber-cómo y saber-qué no tiene las consecuencias políticas previstas por Stanley. Algunas versiones del “intelectualismo” tienen el mismo potencial para alinearse con sistemas políticos jerárquico que algunas versiones del “anti-intelectualismo”. En consecuencia, el debate en torno a las nociones de saber-cómo y saber-qué no tiene incidencia sobre la preocupación más reciente de Stanley acerca de las ideologías falsas.

This note is a friendly amendment to Marti's analysis of the failure of Føllesdal's argument that modal distinctions collapse in Carnap's logic S2. Føllesdal's argument turns on the treatment of descriptions. Marti considers how modal descriptions, which Carnap banned, might be handled; she adopts an approach which blocks Føllesdal's argument, but requires a separate treatment of non-modal descriptions. I point out that a more general treatment of descriptions in S2 is possible, and indeed is implicit in Marti's informal discussion, and that this treatment also blocks Føllesdal's argument. Further, I show by a semantic argument that no revised version of Føllesdal's argument could establish a collapse of modal distinctions
