Abstract: One of the institutional highlights of the encounter between Austrian “wissen¬schaftliche Philosophie” and French “philosophie scientifique” in the first half of the 20th century was the “First International Congress for Unity of Science” that took place 1935 in Paris. In my contribution I deal with an episode of the philosophical mega-event whose protagonist was the American philosopher and semiotician Charles William Morris. At the Paris congress he presented his programme of a comprehensive, practice-oriented scientific philosophy and, in a more (...) elaborated version he published it two years later in Logical Positivism, Pragmatism and Scientific Empiricism (Morris 1937). Morris aimed at a synthesis of formalism, pragmatism, and traditional empiricism that combined the virtues of these accounts while avoided their shortocmings. The core of approach was a comprehensive theory of the concept of meaning. Through an analysis of the concept of meaning he sought to sort out the existing differences and the options for a possible future rapprochment between logical empiricism and pragmatism. Against the overly narrow logical empiricist understanding of philosophy as the syntax of the language of science Morris argued for a “scientific pragmatism” that comprised four levels: (1) Philosophy as Logic of Science, (2) Philosophy as Clarification of Meaning (Peirce), (3) Philosophy as Empirical Axiology (Dewey), and (4) Philosophy as Empirical Cosmology (Whitehead).

APA PsycNET abstract: This is the first volume of a two-volume work on Probability and Induction. Because the writer holds that probability logic is identical with inductive logic, this work is devoted to philosophical problems concerning the nature of probability and inductive reasoning. The author rejects a statistical frequency basis for probability in favor of a logical relation between two statements or propositions. Probability "is the degree of confirmation of a hypothesis (or conclusion) on the basis of some given evidence (...) (or premises)." Furthermore, all principles and theorems of inductive logic are analytic, and the entire system is to be constructed by means of symbolic logic and semantic methods. This means that the author confines himself to the formalistic procedures of word and symbol systems. The resulting sentence or language structures are presumed to separate off logic from all subjectivist or psychological elements. Despite the abstractionism, the claim is made that if an inductive probability system of logic can be constructed it will have its practical application in mathematical statistics, and in various sciences. 16-page bibliography.

"This book is valuable as expounding in full a theory of meaning that has its roots in the work of Frege and has been of the widest influence.

A great mathematician and teacher, and a physicist and philosopher in his own right, bridges the gap between science and the humanities in this exposition of the philosophy of science. He traces the history of science from Aristotle to Einstein to illustrate philosophy's ongoing role in the scientific process. In this volume he explains modern technology's gradual erosion of the rapport between physical theories and philosophical systems, and offers suggestions for restoring the link between these related areas. This book is (...) suitable for undergraduate students and other readers. 1962 ed. Index. 36 figures. (shrink)

This paper offers a refutation of J. C. Pinto de Oliveira's recent critique of revisionist Carnap scholarship as giving undue weight to two brief letters to Kuhn expressing his interest in the latter's work. First an argument is provided to show that Carnap and Kuhn are by no means divided by a radical mismatch of their conceptions of the rationality of science as supposedly evidenced by their stance towards the distinction of the contexts of discovery and justification. This is followed (...) by an argument to the effect that the fact that Carnap's own work concentrated on formal aspects of scientific theories does not licence the conclusion that he thought historical investigations and concerns irrelevant for what we nowadays would rightly call "philosophy of science".

Foundations of the theory of signs.--Signs, language, and behavior.--Five semiotical studies.

For several decades, Dr. Morris has worked primarily with twoproblems: the development of a general theory of signs, and thedevelopment of a general theory of value. He approached both problemsin terms of George Mead's theory of action or behavior. This bookbrings together these two lines of development.

He approached both problems in terms (...) of George Mead's theory of action or behavior. This book brings together these two lines of development. In many languages there is a term like the English "meaning" which has two poles: that which something signifies and the value or significance of what is signified. The nature of signification and significance, as well as their relations within human behavior, is the subject matter of this book. This book is addressed to philosophers and to students of the behavioral sciences, but it will also appeal to anyone seriously interested in the study of human communication. (shrink)

It is proposed to examine the consequences which ensue if philosophy is deliberately oriented around the methods and results of science. That such reorientation has been more or less unconsciously taking place for centuries is evident; the problem demands particular discussion at this time only because the reorientation has gone so far and with such success as to challenge seriously certain past conceptions of philosophy and to demand of philosophers what, if anything, is left for them to do. For present (...) purposes the revolution indicated will be regarded as a fait accompli, and the sole concern will be with what alternatives remain open. The conclusions differ from those of certain others who accept the same fait accompli only in believing that more alternatives do in fact remain open than they envisage. (shrink)

Value judgments are meaningless. This thesis was one of the notorious tenets of Carnap's mature logical empiricism. Less well known is the fact that in the Aufbau values were considered as philosophically respectable entities that could be constituted from value experiences. About 1930, however, values and value judgments were banished to the realm of meaningless metaphysics, and Carnap came to endorse a strict emotivism. The aim of this paper is to shed light on the question why Carnap abandoned his originally (...) positive attitude concerning values. It is argued that his non-cognitivist attitude was the symptom of a deep-rooted and never properly dissolved tension between conflicting inclinations towards Neokantianism and Lebensphilosophie. In America Carnap's non-cognitivism became a major obstacle for a closer collaboration between logical empiricists and American pragmatists. Carnap's persisting adherence to the dualism of practical life and theoretical science was the ultimate reason why he could not accept Morris's and Kaplan's pragmatist theses that cognitivism might well be compatible with a logical and empiricist scientific philosophy.

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. 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. (shrink)

The developments of recent years have made it more and more clear that one of the most fruitful approaches to the science of science, i.e. to a logical, epistemological and methodological analysis of science, consists in the analysis of the language of science. This analysis is meant not only as an analysis of the general structure of the scientific language, but also as an analysis of the expressions of that language as they are used in science, e.g. of the words (...) used, of the sentences of different forms asserted by scientists, of the theories consisting of such sentences, of proofs and derivations for such sentences, etc. (shrink)

Rudolf Carnap and W. V. Quine, two of the twentieth century's most important philosophers, corresponded at length—and over a long period of time—on matters personal, professional, and philosophical. Their friendship encompassed issues and disagreements that go to the heart of contemporary philosophic discussions. Carnap was a founder and leader of the logical positivist school. The younger Quine began as his staunch admirer but diverged from him increasingly over questions in the analysis of meaning and the justification of belief. That they (...) remained close, relishing their differences through years of correspondence, shows their stature both as thinkers and as friends. The letters are presented here, in full, for the first time. The substantial introduction by Richard Creath offers a lively overview of Carnap's and Quine's careers and backgrounds, allowing the nonspecialist to see their writings in historical and intellectual perspective. Creath also provides a judicious analysis of the philosophical divide between them, showing how deep the issues cut into the discipline, and how to a large extent they remain unresolved. (shrink)
