As a leading member of the Vienna Circle, Rudolph Carnap's aim was to bring about a "unified science" by applying a method of logical analysis to the empirical data of all the sciences. This work, first published in English in 1934, endeavors to work out a way in which the observation statements required for verification are not private to the observer. The work shows the strong influence of Wittgenstein, Russell, and Frege.

Graham and Maitzen think my CORNEA principle is in trouble because it entails “intolerable violations of closure under known entailment.” I argue that the trouble arises from current befuddlement about closure itself, and that a distinction drawn by Rudolph Carnap, suitably extended, shows how closure, when properly understood, works in tandem with CORNEA. CORNEA does not obey Closure because it shouldn’t: it applies to “dynamic” epistemic operators, whereas closure principles hold only for “static” ones. What the authors see (...) as an intolerable vice of CORNEA is actually a virtue, helping us see what closure principles should—and shouldn’t—themselves be about. (shrink)

Most handbooks on statistics and the theory of probability leave the reader in a mysterious tangle of mathematical rules for computing apparently arbitrarily chosen numerical functions. At first sight, then, a treatise on the Logical Foundations of Probability raises hopes that it will be a guide to clarity in these matters. These hopes are strengthened if the reader remembers that the author, Professor Rudolph Carnap of the University of Chicago, is noted for his thesis that philosophy is the (...) study of the logic of science. On the other hand, a first glance into this book may discourage a reader who, though familiar with statistics, is not familiar with modern logic and its notation. For this reason particularly I shall try to give an account of this book that will enable the interested student to form some opinion of its usefulness to him. (shrink)

Thirty years after the publication of Thomas Kuhn’s The Structure of Scientific Revolutions, sharp disagreement persists concerning the implications of Kuhn’s "historicist" challenge to empiricism. I discuss the historicist movement over the past thirty years, and the extent to which the discourse between two branches of the historical school has been influenced by tacit assumptions shared with Rudolf Carnap’s empiricism. I begin with an examination of Carnap’s logicism --his logic of science-- and his 1960 correspondence with Kuhn. I (...) focus on problems in the analysis applied to the unit of metascientific study or appraisal, arguing for a reassessment of historicist treatment of the internal/external distinction and historiographic meta-methodology. The critique of objectivism and relativism that eventuates from this re-assessment is a double-edged blade, undercutting both objectivist and relativist treatments of cognitive evaluation and scientific change. I use it to cut across an otherwise diverse group of historicist-influenced writers, including Imre Lakatos, Larry Laudan, H. M. Collins, Stephen Stich. I. Introduction.. (shrink)

The first chapters of Michalos’ book give an account of the controversy between Karl Popper and Rudolph Carnap following the former’s critique of Carnap in "Degree of Confirmation". Michalos very compactly summarizes the controversy and argues: 1) that Popper was mistaken when he tried to show that Carnap always identified the quantitative degree of confirmation with the acceptability of scientific theories; 2) that Popper is mistaken in accusing Carnap of confusing classificatory, comparative, and quantitative concepts; (...) 3) that a conflict between Popper and Carnap, apparently over the problem of unrestricted universals, was in fact over the everyday practical use of such universal sentences; 4) that Popper’s critique of Carnap’s theorem for the singular predictive inference is incorrect because Popper construes the theorem with respect to two different kinds of evidential statements. The final chapters of the book deal with some additional issues that have developed out of the central controversy. One chapter consists largely in a reply to Imre Lakatos in further defense of Carnap. A second presents a critique of the Hintikka-Hilpinen acceptance rule. The last chapter is a comparison of cost—benefit versus utility acceptance rules in which Michalos claims to show the superiority of the former. In general, the book is an attempt to defend an inductive logic against the criticisms offered by Popperian deductive methodologists. A great deal of this material already appeared in various forms. The book is useful insofar as it collects material in one place and provides references to the important contributions to the controversy. Unfortunately, the book is cramped, explicitly discussing only some of the narrow issues found in the journal literature, and some sections are so compact as to be incomprehensible without extensive knowledge of the source material. Michalos might have given himself wider scope so that he could develop the implications of these limited problems for the broader issues of the philosophy of science.—K. M. (shrink)

L'idée d'associer probabilité et induction n'est pas propre au xxe siècle, mais elle a reçu un développement systématique lorsque les philosophes néo-positivistes s'en sont emparés. Dès les années 1940, le philosophe Rudolf Carnap s'est proposé de relever le «défi humien» en fondant une théorie de la confirmation par la construction d'une logique probabiliste dite «inductive». Ce projet avait été esquissé à Cambridge dans les années 1920 par l'économiste John M. Keynes. Examiner le programme de Carnap dans sa totalité, (...) le situer dans son contexte historique, suivre son évolution et les influences qu'il a eues, tels sont les buts de cet article. The idea of associating probability and induction is not a theme suitable for the xxth century but it has received a systematic development when the neo-positivist philosophers seized it. Beginning with the 1940's, the philosopher Rudolph Carnap proposed to affront the «Humian challenge» by founding a theory of confirmation through the construction of a probabilistic logic called «inductive». This project had been outlined in Cambridge during the 1920's by the economist John M. Keynes. To examine Carnap's program in its totality, to situate it in its historical context, to follow its evolution and the influences it has had, these are the aims of this article. (shrink)

Rudolph Carnap’s Aufbau was one of the more ambitious philosophical programs of the twentieth century. His proposal was to begin with elementarerlebnisse —cross sections of one total stream of experience temporally limited by the least perceivable segment of time—and an undefined primitive relation, recollection of similarity, holding between the elementary experiences. Without any further non-logical terms, the goal was to utilize a logic, such as that of Principia Mathematica, and actually to construct logically, or to define formally, all (...) the kinds of entities, phenomenal, physical, psychological and cultural, which we usually take to make up our world. Unfortunately, the program is not completed. Only what Carnap refers to as the lower levels is actually formally constructed—that is, what might be called the phenomenal level. The remainder of the constructional program is only suggested in outline. (shrink)

Yehoshua Bar-Hillel and Rudolph Carnap’s classical theory of semantic information entails the counterintuitive feature that inconsistent statements convey maximal information. Theories preserving Bar-Hillel and Carnap’s modal intuitions while imposing a veridicality requirement on which statements convey information—such as the theories of Fred Dretske or Luciano Floridi—avoid this commitment, as inconsistent statements are deemed not information-conveying by fiat. This paper produces a pair of paradoxical statements that such “veridical-modal” theories must evaluate as both conveying and not conveying information, (...) although Bar-Hillel and Carnap’s theory accommodates these statements without inconsistency. Moreover, the paradoxes are independently interesting as the mode in which they self-refer bears on their evaluation. (shrink)

The paper traces, historically and systematically, the influence of Carnap’s philosophical program on the writings of Nelson Goodman, focusing on the relationship between Carnap’s Aufbau and Goodman’s Structure of Appearance. In particular, drawing on unpublished material from the Carnap Research Archives, I show that Carnap had already anticipated Goodman’s criticism of the method of quasi-analysis and that Goodman misconstrued the status of this procedure on several counts. I also argue that Carnap’s anti-metaphysical stance left his (...) approach with an explanatory deficit which Goodman’s pragmatist pluralism is able to address. (shrink)

Platonism is the most pervasive philosophy of mathematics. Indeed, it can be argued that an inarticulate, half-conscious Platonism is nearly universal among mathematicians. The basic idea is that mathematical entities exist outside space and time, outside thought and matter, in an abstract realm. In the more eloquent words of Edward Everett, a distinguished nineteenth-century American scholar, "in pure mathematics we contemplate absolute truths which existed in the divine mind before the morning stars sang together, and which will continue to exist (...) there when the last of their radiant host shall have fallen from heaven." In What is Mathematics, Really?, renowned mathematician Rueben Hersh takes these eloquent words and this pervasive philosophy to task, in a subversive attack on traditional philosophies of mathematics, most notably, Platonism and formalism. Virtually all philosophers of mathematics treat it as isolated, timeless, ahistorical, inhuman. Hersh argues the contrary, that mathematics must be understood as a human activity, a social phenomenon, part of human culture, historically evolved, and intelligible only in a social context. Mathematical objects are created by humans, not arbitrarily, but from activity with existing mathematical objects, and from the needs of science and daily life. Hersh pulls the screen back to reveal mathematics as seen by professionals, debunking many mathematical myths, and demonstrating how the "humanist" idea of the nature of mathematics more closely resembles how mathematicians actually work. At the heart of the book is a fascinating historical account of the mainstream of philosophy--ranging from Pythagoras, Plato, Descartes, Spinoza, and Kant, to Bertrand Russell, David Hilbert, Rudolph Carnap, and Willard V.O. Quine--followed by the mavericks who saw mathematics as a human artifact, including Aristotle, Locke, Hume, Mill, Peirce, Dewey, and Lakatos. In his epilogue, Hersh reveals that this is no mere armchair debate, of little consequence to the outside world. He contends that Platonism and elitism fit well together, that Platonism in fact is used to justify the claim that "some people just can't learn math." The humanist philosophy, on the other hand, links mathematics with geople, with society, and with history. It fits with liberal anti-elitism and its historical striving for universal literacy, universal higher education, and universal access to knowledge and culture. Thus Hersh's argument has educational and political ramifications. Written by the co-author of The Mathematical Experience, which won the American Book Award in 1983, this volume reflects an insider's view of mathematical life, based on twenty years of doing research on advanced mathematical problems, thirty-five years of teaching graduates and undergraduates, and many long hours of listening, talking to, and reading philosophers. A clearly written and highly iconoclastic book, it is sure to be hotly debated by anyone with a passionate interest in mathematics or the philosophy of science. (shrink)

First published in 1949 expressly to introduce logical positivism to English speakers. Reichenbach, with Rudolph Carnap, founded logical positivism, a form of epistemofogy that privileged scientific over metaphysical truths.

In this paper, I revisit W. V. Quine’s thesis of indeterminacy of translation. I think Quine’s arguments for the thesis are marred by his controversial assumptions about language that amount to a kind of linguistic behaviorism. I hope to cast a new light on the thesis by presenting a strong argument for the thesis that does not rest on those assumptions. The argument that I present in the paper results from adapting Benson Mates’s objection to Rudolph Carnap’s analysis (...) ofsynonymy as intensional isomorphism. (shrink)

About this book Hilary Whitehall Putnam was one of the leading philosophers of the second half of the 20th century. As student of Rudolph Carnap's and Hans Reichenbach's, he went on to become not only a major figure in North American analytic philosophy, who made significant contributions to the philosophy of mind, language, mathematics, and physics but also to the disciplines of logic, number theory, and computer science. He passed away on March 13, 2016. The present volume is (...) a memorial to his extraordinary intellectual contributions, honoring his contributions as a philosopher, a thinker, and a public intellectual. It features essays by an international team of leading philosophers, covering all aspects of Hilary Putnam's philosophy from his work in ethics and the history of philosophy to his contributions to the philosophy of science, logic, and mathematics. Each essay is an original contribution. -/- Author information James Conant, Univ. of Chicago/Univ. of Leipzig, USA/Germany; Sanjit Chakraborty, IISER Kolkata/VIT-AP University, India. (shrink)

Ranging from Joseph Bellamy to Hilary Putnam, and from early New England Divinity Schools to contemporary university philosophy departments, historian Bruce Kuklick recounts the story of the growth of philosophical thinking in the United States. Readers will explore the thought of early American philosphers such as Jonathan Edwards and John Witherspoon and will see how the political ideas of Benjamin Franklin, Thomas Paine and Thomas Jefferson influenced philosophy in colonial America. Kuklick discusses The Transcendental Club (members Henry David Thoreau, Ralph (...) Waldo Emerson) and describes the rise of pragmatism centered on Metaphysical Club of Cambridge (and members William James, Oliver Wendell Holmes, and Charles Peirce). He examines the profound impact Darwinism had on American philosophy and looks at Idealists such as the Kantian Josiah Royce and the Hegelian John Dewey. The book shows how, in the twentieth century, the Nazi conquest of Europe unleashed a flood of European intellectuals onto these shores, including such major thinkers as Theodore Adorno, Erich Fromm, Rudolph Carnap, and Alfred Tarski. Finally, Kuklick examines the contributions of such contemporary philosophers as Sidney Hook and Willard Quine and such books as John Rawl's A Theory of Justice and Herbert Marcuse's One Dimensional Man. Kuklick pulls no punches in portraying the state of American philosophy today and its contested role in the intellectual life of the nation and the world. The range of philosophical thought in our nation's history has been great, from Edwards's Religious Affections to Kuhn's The Structure of Scientific Revolutions, and Bruce Kuklick has captured it all in a book that blends intricate details with sweeping vision.

Philosophers often write in a particular mood; their work is playful, strident, strenuous, or nostalgic. On the face of it, these moods contribute little to a philosophical argument and are merely incidental. However, I will argue that the cognitive science of moods and emotions offers us reasons to suspect that mood is relevant for philosophical texts. I use examples from Friedrich Nietzsche and Rudolph Carnap to illustrate the role moods play in their arguments. As readers and writers of (...) philosophical texts, we do well to attend to mood.

Among philosophers of science nearly a century ago the dominant attitude was that (in Rudolph Carnap’s words) philosophy of science was “like science itself, neutral with respect to practical aims, whether they are moral aims for the individual, or political aims for a society.” The dominant attitude today is not much different: our aim is still to articulate scientific rationality, and our understanding of that rationality still excludes the moral and political. I contrast this with the growing entanglements (...) within the sciences of the ethical and the epistemic, and I suggest ways in which philosophers of science can usefully respond. †To contact the author, please write to: Department of Philosophy, 100 Malloy Hall, University of Notre Dame, Notre Dame, IN 46556; e‐mail: [email protected].

The verification theory of meaning aims to characterise what it is for a sentence to be meaningful and also what kind of abstract object the meaning of a sentence is. A brief outline is given by Rudolph Carnap, one of the theory's most prominent defenders: If we knew what it would be for a given sentence to be found true then we would know what its meaning is. [...] thus the meaning of a sentence is in a certain (...) sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. [4: 420] In short, the verification theory of meaning claims that the meaning of a sentence is the method of its verification. (shrink)

Theories of meaning developed within the analytic tradition, starting with Gottlob Frege, and within continental philosophy, starting with Husserl, can be distinguished by their disagreement about the phenomenon of collapse or failure of meaning. Our text focuses on Frege’s legacy, taken up by Rudolph Carnap, which culminated in a view of the collapse of meaning defined first by a purely syntactic conception of categorial error and second, when Tarski entered the scene, by the paradoxes created by the conflict (...) between the use of the predicate truth and the concept of proof. As positivism’s conventionalism and late model-theoretic semantics became the paradigms derived from this position, the result, in our view, was a conception of meaning success and meaning failure dominated by dependence on a technological conception. We will argue that this dependence leads to the inability to evaluate the breaks in rational parameters and crises of meaning addressed by the phenomenological and transcendental perspectives. Husserl’s critique of logic as technology is the basis for the reflexive standpoint on the phenomena of meaning failure that leads to a theoretical and eidetic ideal approach to that phenomenon. It is then suggested that this phenomenological reflective standpoint on the problem of meaning failure is the origin of the doors that lead to the divergent paths between the analytic and continental traditions. Thus, this is an article with three argumentative phases connected into a larger unity. The first phase presents Husserl’s critique of a purely extensional, syntactic, and recursive conception of logical consequence and the concept of truth; the second presents Hussel’s larger conception of meaning-failure; the third—presented in an appendix— presents a lesson on the division between continental and analytic philosophy.

The early writings of Wilfrid Sellars are characterized by the analysis of themes and problems from Rudolph Carnap's philosophy of language. In particular, Sellars investigated the notion of "material'' rules of inference and explored the possibility of a "pure'' pragmatics. In these initial researches Sellars laid the foundations for his inferentialist analysis of meaning. A crucial component of such an analysis is the seminal form of rational expressivism that Sellars began to develop at the time. In this paper (...) I address the genesis of this idea and some of the main implications that it has on the characterization of the space of reasons. (shrink)

The art of memory started with Aristotle’s questions on memory. During its long evolution, it had important contributions from alchemists, was transformed by Ramon Llull and apparently ended with Giordano Bruno, who was considered the best known representative of this art. This tradition did not disappear, but lives in the formulations of our modern scientific theories. From its initial form as a method of keeping information via associations, it became a principle of classification and structuring of knowledge. This principle, which (...) we here name differentiation with stratification, is a structural design behind classical mechanics. Integrating two different traditions of science in one structure, this physical theory became the modern paradigm of science. In this paper, we show that this principle can also be formulated as a set of questions. This is done via an analysis of theories, based on the epistemology of observational realism. A combination of Rudolph Carnap’s concept of theory as a system of observational and theoretical languages, with a criterion for separating observational languages, based on analytical psychology, shapes this epistemology. The ‘nuclear’ role of the observational laws and the differentiations from these nucleus, reproducing the general cases of phenomena, reveals the memory art’s heritage in the theories. Here in this paper we argue that this design is also present in special relativity and in quantum mechanics. (shrink)

According to the standard account, logical positivism was the philosophical foundation of psychological neo-behaviorism. Smith (1986) has questioned this interpretation, suggesting that neo-behaviorism drew its philosophical inspiration from a different tradition, one more in keeping with naturalistic epistemology. Smith does not deny, however, the traditional interpretation of the philosophy of logical positivism, which sets it apart from naturalistic epistemology. In this article I suggest (following recent historical scholarship) that a more careful reading of the leading figure of logical positivism, (...) class='Hi'>Rudolph Carnap, shows an important naturalistic component in his philosophy. Hence, we must reevaluate our standard interpretation of the philosophy of logical positivism and its relation to psychological neo-behaviorism. (shrink)

Hans Reichenbach was a formidable figure in early-twentieth-century philosophy of science. Educated in Germany, he was influential in establishing the so-called Berlin Circle, a companion group to the Vienna Circle founded by his colleague Rudolph Carnap. The movement they founded—usually known as "logical positivism," although it is more precisely known as "scientific philosophy" or "logical empiricism"—was a form of epistemology that privileged scientific over metaphysical truths. Reichenbach, like other young philosophers of the exact sciences of his generation, was (...) deeply impressed by the far-reaching changes in physics brought about by Einstein's special and general theories of relativity. Reichenbach responded to scientific advances by doing fundamental work in space-time theories, in quantum mechanics, in statistical mechanics, and in the development of probability theory—making him the most important philosopher of physics in the first generation of logical empiricism. Forced from his academic position by the Nazi race laws in 1933, Reichenbach wrote _Experience and Prediction_ at the University of Istanbul, where had had fled, expressly to introduce logical positivism to English speakers. In the two decades following World War II, during the explosion of scientific advances in North America, logical positivism was the reigning theory of the philosophy of science and Reichenbach was at the peak of his career. But, inevitably, support for logical positivism began to wane as it became obvious that the justification of scientific theories could not be entirely resolved by relying on strictly formal, technical processes. The growth of the discipline of the history of philosophy of science, which has created an audience of scholars eager for seminal classics in scientific philosophy, and the evidence supporting a historicist paradigm within logical positivism are two important reasons to make _Experience and Prediction_ available once again. "Hans Reichenbach's_ Experience and Prediction_ is one of the most important books in twentieth-century philosophy of science. Its author was, along with Rudolf Carnap, one of the two principal ambassadors to North America of the exciting new European philosophical movement known here under the names 'Logical Positivism' and 'Scientific Philosophy.' In 1938, when the book was published, Reichenbach was an exile from his native Germany, teaching in Istanbul, Turkey, and about to emigrate to the United States to take up a prestigious position at UCLA. He wrote_ Experience and Prediction_ in English as his calling card to his new American colleagues. More than any other single book,_ Experience and Prediction_ set the agenda for the new discipline of the philosophy of science that was to emerge after World War II as, perhaps, the most exciting new area in North American philosophy. Many of the problems still at the focus of discussion were given their classic formulations in this book. Long out of print,_ Experience and Prediction_ appears here in a new edition accompanied by a splendid historical introduction by the noted young philosopher and historian of the philosophy of science, Alan Richardson. A jewel of a book may once again be appreciated in its proper setting." —Don A. Howard, University of Notre Dame. (shrink)

The papers comprising Zur Farbenlehre, best known portion of Goethe's writings on color and optics, appeared between 1808 and 1810. Portions of Zur Farbenlehre, translated by the painter Charles Lock Eastlake and frequently reprinted under the title Theory of Colours, achieved immediate notoriety because of Goethe's insistent questioning of Newton's methodology. Acknowledging no mentors except Theophrastus and the physicist Robert Boyle, Goethe compared the Newtonian theory of colors--indelicately, some think--to a once proud castle still revered long after it has fallen (...) into decay. The furor aroused by this intemperate analogy has not fully subsided yet. During the twentieth century Max Planck answered the impertinence with a vigorous ad hominem attack and Rudolph Carnap followed suit. We still lack a serious analysis of Goethe's color theories or his arguments against Newton. And the early vituperation seems quaint. Questioning Newton's methodology--or even his epistemology--is a legitimate activity and has even become commonplace. The 1840 edition of Eastlake's translation enjoys a perennial popularity among artists and a few perceptual psychologists, who have been allowed to monopolize for too long a book which is primarily a highly provocative inquiry in the philosophy of science. Someday an imaginative publisher may be inspired to make available more extensive translations of Goethe's copious writings on color, complemented by the type of careful editing, annotation and analysis which I. Bernard Cohen and Alexander Koyré provide for the writings of Newton. Until then one is grateful for Eastlake.--P. S. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Continental Divide: Heidegger, Cassirer, DavosSebastian LuftPeter E. Gordon. Continental Divide: Heidegger, Cassirer, Davos. Cambridge, MA: Harvard University Press, 2010. Pp. 448. Cloth, $39.95.Much ink has been spilled on the dispute between Ernst Cassirer and Martin Heidegger that took place in the Swiss resort town Davos in 1929—famous since Thomas Mann staged his Magic Mountain there—and which has since been referred to as the “Davos Dispute.” While the debate (...) itself and accounts accompanying it have been widely known to historians [End Page 508] of philosophy, Harvard historian Peter E. Gordon shows in this marvelous new book how memory has shaped the event into something much larger than anyone could have foreseen. It is, Gordon claims, the silent work of memory that has made this debate, rather innocuous at the time, into what can be retrospectively be considered the truly earth-shattering philosophical event of the twentieth century.In hindsight, the symbolism of the debate between a German who became a leading Nazi philosopher in 1933 and a Jew who, in the same year, was dismissed from his professorship and forced to flee Germany, could not be greater. It only grows if one connects the historic events with their respective philosophies: on the one side the liberal modern Cassirer, whose philosophy allegedly glorified the Weimar stalemate, and on the other side the radical Heidegger, whose call for “authentic existence” took on a bone-chilling reality as he embraced Hitler in 1933 as the führer to lead Germany back to its authentic roots.Two volumes—the 1999 collection, 70 Jahre Davoser Disputation, edited by E. Rudolph and D. Kaegi, and, in 2000, A Parting of the Ways by Michael Friedman—were the first to delve into the debate’s symbolic meaning. It was Friedman’s thesis that the fateful “parting of the ways” between Continental and Analytic philosophy could be traced to this meeting, which was also attended by Rudolf Carnap. Despite these studies, there has until now not been a comprehensive treatment that pulls together all threads into one narrative, covering the entire intellectual, historical, cultural, and philosophical landscape of the time. Gordon’s book achieves just that and will be, for years to come, the landmark work on this encounter.The book begins from the background in post-World War I philosophy in Germany, which was perceived, along with culture, as being in crisis (ch. 1), to “set the stage” on the “Magic Mountain” (ch. 2). It proceeds to summarize the individual lectures by Cassirer and Heidegger, giving a detailed interpretation of the protocol prepared by students of the interlocutors (chs. 3–4). The author then takes a deep breath in chapter 5 to place the debate in the larger context of Cassirer’s and Heidegger’s philosophies. But the story does not end there, as chapter 6 examines the relation between both thinkers after the debate. Finally, in chapter 7, Gordon assesses the newer debates concerning this dispute up to the debate between Bourdieu and Habermas concerning Heidegger’s Nazi involvement, though it does not re-engage with Friedman’s thesis, as might have been desired.Regarding his interpretation, Gordon juxtaposes Cassirer’s and Heidegger’s philosophies along the Kantian distinction between spontaneity and receptivity, where both paradigms make different claims on the “normative image of humanity” (5 ff.). Whether humanity is interpreted as spontaneous and world-creating, in optimistic Enlightenment terms (Cassirer), or as receptive and open to the world, i.e. as the “shepherd” rather than the “lord of being” (Heidegger), both are answering the fourth of Kant’s questions, “What is man?” While this distinction is useful for understanding the basic relation between them, it is also—as the author would concede—somewhat too coarse to do justice to their mutual differences and commonalities. Were one to assert a systematic critique, Gordon does not really make up his mind as to the true significance of these paradigms: are they mutually exclusive oppositions or, as he implies elsewhere, two alternative versions of philosophical modernism with a common ground? There is evidence for both readings. This question, however, is for the philosopher to answer—the philosopher who wants to push... (shrink)

We present a novel semantic and conversational framework for a class of gradable-like constructions. These include metalinguistic comparatives, like "Ann is more a linguist than a philosopher", as well as metalinguistic equatives, degree modifications, and conditionals. To the extent previous literature discusses such metalinguistic gradability, the focus has been on comparatives. We extend our account of metalinguistic comparatives (Rudolph & Kocurek 2020) to cover a broader range of metalinguistic gradable constructions. On our semantic expressivist view, these all serve in (...) various ways to express speakers' relative commitments to different linguistic interpretations. (shrink)

Dieses Buch will die systematische Darstellung einer solchen Methode, der "logischen Syntax", geben (nahere Erlauterungen in der Einleitung, §§ 1, 2). In unserem "Wiener Kreis" und in manchen ahnlich gerich­ teten Gruppen (in Polen, Frankreich, England, USA. und ver­ einzelt sogar in Deutschland) hat sich gegenwartig die Auffassung immer deutlicher herausgebildet, daB die traditionelle meta· physische Philosophie keinen Anspruch auf Wissenschaftlichkeit machen kann. Was an der Arbeit des Philosophen wissenschaft· lich haltbar ist, besteht - soweit es nicht empirische Fragen betrifft, die der Realwissenschaft zuzuweisen sind - in logischer Analyse. Die logische Syntax will nun ein Begriffsgeb8. ude, eine Sprache liefem, mit deren Hilfe die Ergebnisse logischer Analyse exakt formulierbar sind. (shrink)
