First published in 2000. This is Volume II of six in the Library of Philosophy series on the Philosophy of Science. Written in 1938, philosophical systems which employ logical methods almost exclusively would undoubtedly be expected to produce non-empirical results. If, however, logic is taken simply as a method of connecting meanings it is not difficult to reconcile logical methods with empirical results. If logical formular, in other words, assert nothing about the meanings of propositions, but simply show how such meanings are connected, then an empiricism based on a logical analysis of meanings is not inconsistent. This is what the Logical Positivists have attempted to do. This book looks at two areas: the foundations of a scientific method free from metaphysics, and the elimination of pseudo-concepts introduced by metaphysics into science and philosophy.
A reinterpretation of the enduring significance of logical positivism.
Philosophy in the twentieth century has been dominated by the urge for analysis, a methodology that is supposed to be comparable in clarity and correctness to scientific thought. In this brilliant and devastating attack on such exaggerated claims, Stanley Rosen demonstrates how analysis alone lacks the power to approach the deepest and most important philosophical questions. He thus provides us with a new and deeper understanding of the nature and limits of analytic thinking.
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.
The title is his own. Herbert Feigl, the provocateur and the soul (if we may put it so) of modesty, wrote to me some years ago, "I'm more of a catalyst than producer of new and original ideas all my life . . . ", but then he com pleted the self-appraisal: " . . . with just a few exceptions perhaps". We need not argue for the creative nature of catalysis, but will simply remark that there are 'new and original ideas' in the twenty-four papers selected for this volume, in the extraordinary aperrus of the 25-year-old Feigl in his Vienna dissertation of 1927 on Zufall und Gesetz, in the creative critique and articulation in his classical monograph of 1958 on The 'Mental' and the 'Physical'; and the reader will want to turn to some of the seventy other titles in our Feigl bibliography appended. Professor Feigl has been a model philosophical worker: above all else, honest, self-aware, open-minded and open-hearted; keenly, devotedly, and even arduously the student of the sciences, he has been a logician and an empiricist. Early on, he brought the Vienna Circle to America, and much later he helped to bring it back to Central Europe. The story of the logical empiricist movement, and of Herbert Feigl's part in it, has often been told, importantly by Feigl himself in four papers we have included here.
Copleston, an Oxford Jesuit and specialist in the history of philosophy, first created his history as an introduction for Catholic ecclesiastical seminaries. However, since its first publication (the last volume appearing in the mid-1970s) the series has become the classic account for all philosophy scholars and students. The 11-volume series gives an accessible account of each philosopher's work, but also explains their relationship to the work of other philosophers.
If there is a movement or school that epitomizes analytic philosophy in the middle of the twentieth century, it is logical empiricism. Logical empiricists created a scientifically and technically informed philosophy of science, established mathematical logic as a topic in and tool for philosophy, and initiated the project of formal semantics. Accounts of analytic philosophy written in the middle of the twentieth century gave logical empiricism a central place in the project. The second wave of interpretative accounts was constructed to show how philosophy should progress, or had progressed, beyond logical empiricism. The essays survey the formative stages of logical empiricism in central Europe and its acculturation in North America, discussing its main topics, and achievements and failures, in different areas of philosophy of science, and assessing its influence on philosophy, past, present, and future.
Friedrich Waismann (1896–1959) was one of the most gifted students and collaborators of Moritz Schlick. Accepted as a discussion partner by Wittgenstein from 1927 on, he functioned as spokesman for the latter’s ideas in the Schlick Circle, until Wittgenstein’s contact with this most faithful interpreter was broken off in 1935 and not renewed when exile took Waismann to Cambridge. Nonetheless, at Oxford, where he went in 1939, and eventually became Reader in Philosophy of Mathematics (changing later to Philosophy of Science), Waismann made important and independent contributions to analytic philosophy and philosophy of science (for example in relation to probability, causality and linguistic analysis). The full extent of these only became evident later when the larger (unpublished) part of his writings could be studied. His first posthumous work The Principles of Linguistic Philosophy (1965, 2nd edn.1997; German 1976) and his earlier Einführung in das mathematische Denken (1936) have recently proved of fresh interest to the scientific community. This late flowering and new understanding of Waismann’s position is connected with the fact that he somewhat unfairly fell under the shadow of Wittgenstein, his mentor and predecessor. Central to this book about a life and work familiar to few is unpublished and unknown works on causality and probability. These are commented on in this volume, which will also include a publication of new or previously scattered material and an overview of Waismann’s life.
