The received view in the history of the philosophy of psychology is that the logical positivists—Carnap and Hempel in particular—endorsed the position commonly known as “logical” or “analytical” behaviourism, according to which the relations between psychological statements and the physical-behavioural statements intended to give their meaning are analytic and knowable a priori. This chapter argues that this is sheer legend: most, if not all, such relations were viewed by the logical positivists as synthetic and knowable only a (...) posteriori. It then traces the origins of the legend to the logical positivists’ idiosyncratic extensional or at best weakly intensional use of what are now considered crucially strongly intensional semantic notions, such as “translation,” “meaning” and their cognates, focussing on a particular instance of this latter phenomenon, arguing that a conflation of explicit definition and analyticity may be the chief source of the legend.

This essay considers the nature of conceptual frameworks in science, and suggests a reconsideration of the role played by philosophy in radical conceptual change. On Kuhn's view of conceptual conflict, the scientist's appeal to philosophical principles is an obvious symptom of incommensurability; philosophical preferences are merely “subjective factors” that play a part in the “necessarily circular” arguments that scientists offer for their own conceptual commitments. Recent work by Friedman has persuasively challenged this view, revealing the roles that philosophical concerns have (...) played in preparing the way for conceptual change, creating an enlarged conceptual space in which alternatives to the prevailing framework become intelligible and can be rationally discussed. If we shift our focus from philosophical themes or preferences to the process of philosophical analysis, however, we can see philosophy in a different and much more significant historic role: not merely as an external source of general heuristic principles and new conceptual possibilities, but, at least in the most important revolutionary developments, as an objective tool of scientific inquiry. I suggest that this approach offers some insight into the philosophical significance of Newton's and Einstein's revolutionary work in physics, and of the interpretation of their work by (respectively) Kant and the logical positivists. It also offers insight into the connections between modern philosophy of science and some traditional philosophical concerns about the nature of a priori knowledge. (shrink)

I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline to (...) provide a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

The nrst of the people to be thanked for their help during the composition of this work is Professor I.M. Bochenski, under whom I had the good fortune to study for an extended period of time. Without his help, it is doubtful that this work would have been writt"l1 at all. Among the other professors who helped along the way, I would like to cite in particular Professors A.F. Utz, M.D. Philippe and N. Luyten of the University of Fribourg. Many (...) friends were present at the birth of the ideas contained in this book. By naming K.G. Ballestrem, T.l. Blakeley and M.F. Gagern, I do not want to slight any of the rest. It was A. Spiekermann in Hollinghofen who saw to it that other preoccupations did not rob me of all the time needed for the study of the subject-matter and to the composition of this treatise. Of particular help in getting sources from the libraries of the world were Miss Lifschitz of the Institute of East-European Studies and Mr. Uldry of the Cantonal Library in Fribourg, Switzerland. Finally, my patient typist, Mrs. Frey in Munster, deserves special mention for her beautiful work. (shrink)

The word "modem" in the title of this book refers primarily to post-medieval discussions, but it also hints at those medieval mo dal theories which were considered modem in contradistinction to ancient conceptions and which in different ways influenced philosophical discussions during the early modem period. The me dieval developments are investigated in the opening paper, 'The Foundations of Modality and Conceivability in Descartes and His Predecessors', by Lilli Alanen and Simo Knuuttila. Boethius's works from the early sixth century belonged (...) to the sources from which early medieval thinkers obtained their knowledge of ancient thought. They offered extensive discus sions of traditional modal conceptions the basic forms of which were: (1) the paradigm of possibility as a potency striving to realize itself; (2) the "statistical" interpretation of modal no tions where necessity means actuality in all relevant cases or omnitemporal actuality, possibility means actuality in some rel evant cases or sometimes, and impossibility means omnitemporal non-actuality; and (3) the "logical" definition of possibility as something which, being assumed, results in nothing contradic tory. Boethius accepted the Aristotelian view according to which total possibilities in the first sense must prove their met tle through actualization and possibilities in the third sense are assumed to be realized in our actual history. On these presump tions, all of the above-mentioned ancient paradigms imply the Principle of Plenitude according to which no genuine possibility remains unrealized. (shrink)

A new direction in philosophy Between 1920 and 1940 logical empiricism reset the direction of philosophy of science and much of the rest of Anglo-American philosophy. It began as a relatively organized movement centered on the Vienna Circle, and like-minded philosophers elsewhere, especially in Berlin. As Europe drifted into the Nazi era, several important figures, especially Carnap and Neurath, also found common ground in their liberal politics and radical social agenda. Together, the logical empiricists set out to reform (...) traditional philosophy with a new set of doctrines more firmly grounded in logic and science. Criticism and decline Because of Nazi persecution, most of the European adherents of logical empiricism moved to the United States in the late 1930s. During the 1940s, many of their most cherished tenets became targets of criticism from outsiders as well as from within their own ranks. Philosophers of science in the late 1950s and 1960s rejected logical empiricism and, starting in the 1970s, presented such alternative programs such as scientific realism with evolutionary epistemology. A resurgence of interest During the early 1980s, philosophers and historians of philosophy began to study logical empiricism as an important movement. Unlike their predecessors in the 1960s-for whom the debate over logical empiricism now seems to have been largely motivated by professional politics-these philosopher no longer have to take positions for or against logical empiricism. The result has been a more balanced view of that movement, its achievements, its failures, and its influence. Hard-to-find core writings now available This collection makes available a selection of the most influential and representative writings of the logical empiricists, important contemporary criticisms of their doctrines, their responses, as well as the recent reappraisals. Introductions to each volume examine the articles in historical context and provide importantbackground information that is vital to a full understanding of the issues discussed.

This abridged and revised edition of the original book (Springer-Verlag Vienna, 2001) offers the only comprehensive history and documentation of the Vienna Circle based on new sources with an innovative historiographical approach to the study of science. With reference to previously unpublished archival material and more recent literature, it refutes a number of widespread clichés about "neo-positivism" or "logical positivism". Following some insights on the relation between the history of science and the philosophy of science, the (...) book offers an accessible introduction to the complex subject of "the rise of scientific philosophy" in its socio-cultural background and European philosophical networks till the forced migration in the Anglo-Saxon world. The first part of the book focuses on the origins of Logical Empiricism before World War I and the development of the Vienna Circle in "Red Vienna" (with the "Verein Ernst Mach"), its fate during Austro-Fascism (Schlick's murder 1936) and its final expulsion by National-Socialism beginning with the "Anschluss" in 1938. It analyses the dynamics of the Schlick-Circle in the intellectual context of "late enlightenment" including the minutes of the meetings from 1930 on for the first time published and presents an extensive description of the meetings and international Unity of Science conferences between 1929 and 1941. The chapters introduce the leading philosophers of the Schlick Circle (e.g., Hans Hahn, Otto Neurath, Rudolf Carnap, Philipp Frank, Felix Kaufmann, Edgar Zilsel) and describe the conflicting interaction between Moritz Schlick and Otto Neurath, the long term communication between Moritz Schlick, Friedrich Waismann and Ludwig Wittgenstein, as well as between the Vienna Circle with Heinrich Gomperz and Karl Popper. In addition, Karl Menger's "Mathematical Colloquium" with Kurt Gödel is presented as a parallel movement. The final chapter of this section describes the demise of the Vienna Circle and the forced exodus of scientists and intellectuals from Austria.The second part of the book includes a bio-bibliographical documentation of the Vienna Circle members and for the first time of the assassination of Moritz Schlick in 1936, followed by an appendix comprising an extensive list of sources and literature.

Logical Positivists had a very lively interest in the revolutionary science of their time, but also in modern art and especially in ‘international style’ architecture. Surprisingly they never published a representative volume or longer statement on art and architecture. But: it is not well known that Otto Neurath, their leading organizer and spokesman, invited the eminent art historian and critic Meyer Schapiro to contribute a volume on art to the International Encyclopedia of Unified Science. Schapiro failed to deliver the (...) promised book. But from the extended correspondence and some material in the Schapiro papers one can describe the general direction the thing would have taken. The correspondence is also very interesting, because it also covers questions of the endangered peace and the approaching war, the academic scene in Europe and in the USA, and surprisingly: Martin Heidegger. Neurath died in 1945, but Schapiro came back to the Heidegger theme in 1968 when he wrote his famous harsh criticism of Heidegger’s programmatic long paper “Das Kunstwerk” where he interprets one of Van Gogh’s shoe-paintings. Schapiro’s short article caused much controversy then. (shrink)

Logical positivism is often characterized as a set of naive doctrines on meaning, method, and metaphysics. In recent decades, however, historians have dismissed this view as a gross misinterpretation. This new scholarship raises a number of questions. When did the standard reading emerge? Why did it become so popular? And how could commentators have been so wrong? This essay reconstructs the history of a “caricature” and rejects the hypothesis that it was developed by ill-informed Anglophone scholars who failed (...) to appreciate the subtleties of European scientific philosophy. It argues that the received view has a more complicated history and was frequently promoted by the European positivists themselves. The essay shows that the view has roots in both American and European scientific philosophy and emerged as a result of the complex interplay between the two communities in the years before the intellectual migration.

In this collection of essays one of the preeminent philosophers of science writing offers a reinterpretation of the enduring significance of logical positivism, the revolutionary philosophical movement centered around the Vienna Circle in the 1920s and 30s. Michael Friedman argues that the logical positivists were radicals not by presenting a new version of empiricism but rather by offering a new conception of a priori knowledge and its role in empirical knowledge. This collection will be mandatory reading for (...) any philosopher or historian of science interested in the history of logical positivism in particular or the evolution of modern philosophy in general.

An outstanding reference source to this challenging subject area, and the first collection of its kind. Essential reading for students and researchers in the history of the philosophy, the history of analytical philosophy and twentieth-century philosophy.

This book is a compact, accessible treatment of the main ideas advanced by the positivists, including Schlick, Carnap, Ayer, and the early Wittgenstein. Oswald Hanfling discusses such ideas as the 'verification principle' ('the meaning of this statement is the method of its verification') and the 'elimination of metaphysics, ' an attempt to show that metaphysical statements, for example about God, are unverifiable and therefore meaningless.

Do the terms “logical positivism” and “logical empiricism” mark a philosophically real and significant distinction? There is, of course, no doubt that the first term designates the group of philosophers known as the Vienna Circle, headed by Moritz Schlick and including Rudolf Carnap, Herbert Feigl, Philipp Frank, Hans Hahn, Otto Neurath, Friedrich Waismann and others. What is debatable, however, is whether the name “logical positivism” correctly distinguishes their doctrines from related ones called “logical empiricism” (...) that emerged from the Berlin Society for Scientific Philosophy around Hans Reichenbach which included Walter Dubislav, Kurt Grelling, Kurt Lewin and a young Carl Gustav Hempel.1 The ..

The two most antagonistic schools in contemporary Western philosophy are Existentialism and Logical Positivism. They have nothing in common but the name of philosophy, and even that they deny each other. There is some kind of discussion going on between even such distant schools as Pragmatism and neo-Thomism; Existentialists and Logical Positivists have nothing but sarcasms for each other. To philosophers familiar only with the Anglo-Saxon scene Existentialism must appear negligible. In the Mediterranean countries, on the other (...) hand, where philosophy is a much more popular pastime, Existentialism has an unparalleled vogue and Logical Positivism is considered a horrible aberration from the naturally speculative course of philosophy. In South America whose philosophical life we are apt to underrate Logical Positivism seems to be known to almost nobody, whereas Existentialism, mostly in its German and anti-religious shape, has become, quite paradoxically, the rallying point of “Liberalism,” liberalism, in Spanish countries, being above all anti-catholicism. Although, ironically enough, both Logical Positivism and modern Existentialism originated in German speaking countries, the split between the two goes vaguely parallel with, and may have found some ready echo in, the different cultural inheritance of the Anglo-Saxon and Latin races. Hence, the subject of this paper would seem far-fetched to those steeped in their own national tradition. There is, however, a growing consciousness of the “one world” function of philosophy, particularly with regard to Eastern and Western philosophy. Would it not be a prerequisite of this more ambitious enterprise to gain a clear conception about the most radical split in our own contemporary Western philosophy, the split between Logical Positivism and Existentialism? This paper is an attempt to establish a perspective permitting a just evaluation of the two philosophies. (shrink)

Due to their acceptance of the verifiability principle, the only way left for logical positivists to argue for the meaningfulness of religious language was to accept some sort of emotivistic conception of it or to reduce it to the description of religious attitude. The verifiability principle, however, suffers from some severe limitations that make it inadequate as a criterion for cognitive meaning. To resolve these problems, logical positivists gave up the requirement of conclusive verifiability and defended a sort (...) of ‘liberalization’ of the verifiability principle. Carnap’s confirmability criterion for cognitive meaning, which is a liberalized form of the verifiability principle, is compatible with an orthodox conception of religious language since, from a theistic perspective, the existence of God can be confirmed through our observational statements.

Logical positivism and the Vienna Circle are almost synonymous. The Vienna Circle grew in strength throughout the 1920s, attracting philosophers such as Rudolf Carnap, Friedrich Waismann, and Otto Neurath and mathematicians and scientists such as Kurt Gödel and Hans Hahn. It started as an intellectual club (initially known as the Ernst Mach Society), with Moritz Schlick, Professor of Philosophy at the University of Vienna, as its leading light. As the club debated and discussed problems in science, logic, and (...) philosophy, a definite consensus emerged. The members of the Vienna Circle were bound, initially at least, by commitments, to.

On 15 October 1959, Rudolf Carnap, a leading member of the recently founded Vienna Circle, came to lecture at the Bauhaus in Dessau, southwest of Berlin. Carnap had just finished his magnum opus, The Logical Construction of the World, a book that immediately became the bible of the new antiphilosophy announced by the logical positivists. From a small group in Vienna, the movement soon expanded to include an international following, and in the sixty years since has exerted a (...) powerful sway over the conduct of the philosophy of science as well as over wide branches of philosophy, economics, psychology, and physics. The site of Carnap’s lecture that day, the Dessau Bauhaus, was a stunning building designed by Walter Gropius and dedicated just three years earlier. Protected by its flat roof and glass walls, the artists, architects, weavers, and furniture designers had made the school a citadel of high modernism. It was here that Carnap addressed an enthusiastic audience on “Science and Life.” “I work in science,” he began, “and you in visible forms; the two are only different sides of a single life.”1 In this paper I will explore this “single life” of which the new philosophy and the new art were to be different facets; in the process, I hope to cast light on the shared modernist impulses that drove both disciplines in the interwar years. 1.

I argue that the analytic method has been circularly used to analyze the concept of “philosophy,” and that the result of this analysis has also been used to criticize African ethnophilosophy as nonphilosophical.

I defend ethnophilosophy against these criticisms, arguing that they are rooted in logical positivism, the view that philosophy essentially involves the use of the methods of science and (...) class='Hi'>logical analysis.

The subject of this paper is the relation of Logical Positivism to Theology. By “Logical Positivism” I mean the doctrine originated by Dr. Wittgenstein and expounded more at length by Professors Carnap, Schlick, and other members of the Viennese Circle in the periodical calledErkenntnis. The clearest account of it in English is that given by Mr. R. B. Braithwaite in the volume calledCambridge University Studies.

Teachers are urged to integrate grammar instruction with lessons on writer's craft, but what does that look like in real classrooms with real kids? In The Craft of Grammar, Jeff Anderson shows how he brings grammar and craft together meaningfully for student writers. Jeff and his sixth-grade students move easily from analyzing sentences to freewrites in writer's notebooks to "express-lane edits" of their writing in daily workshops. The lessons, individual conferences, and small-group activities on the video demonstrate how to use (...) high-quality children's and young adult literature as mentor texts and as an alternative to "Daily Oral Language." This sixty-minute DVD includes examples of: developing whole-class lessons focused on short mentor text; linking the writer's notebook to grammar instruction; assisting students in individual conferences as they test new writing strategies and analyze text; scaffolding learning through guided practice and small-group work; creating mnemonic devices to help students retain key rules; celebrating student success and tactfully correcting errors. Jeff presents simple and imaginative tools and memory devices—from the whoop of the AAAWWUBIS to the clever and catchy FANBOYS—that help students see the value of grammar and mechanics in crafting powerful writing and retain that knowledge. Filmed in his diverse, Title I classroom in San Antonio, Texas, and featuring Jeff's unique brand of energy, passion, and self-deprecating humor, The Craft of Grammar helps teachers of intermediate and adolescent writers find new and engaging ways to connect the writing process with grammar and mechanics.

This paper reconstructs the American reception of logical positivism in the early 1930s. I argue that Moritz Schlick (who had visiting positions at Stanford and Berkeley between 1929 and 1932) and Herbert Feigl (who visited Harvard in the 1930-31 academic year) played a crucial role in promoting the *Wissenschaftliche Weltauffassung*, years before members of the Vienna Circle, the Berlin Group, and the Lvov-Warsaw school would seek refuge in the United States. Building on archive material from the Wiener Kreis (...) Archiv, the Harvard University Archives, and the Herbert Feigl Papers, as well as a large number of publications in American philosophy journals from the early 1930s, I reconstruct the subtle transformation of the American philosophical landscape in the years immediately preceding the European exodus. I argue that (1) American philosophical discussions about meaning and significance and (2) internal dynamics in the Vienna Circle between 1929 and 1931 significantly impacted the way in which US philosophers came to perceive logical positivism.
