The philosophical writings of Otto Neurath, and their central themes, have been described many times, by Carnap in his authobiographical essay, by Ayer and Morris and Kraft decades ago, by Haller and Hegselmann and Nemeth and others in recent years. How extraordinary Neurath's insights were, even when they perhaps were more to be seen as conjectures, aperfus, philosophical hypotheses, tools to be taken up and used in the practical workshop of life; and how prescient he was. A few examples may be helpful: (1) Neurath's 1912 lecture on the conceptual critique of the idea of a pleasure maximum ...

xi should hope for "first and foremost" from any historical investigation, including his own, was that "it may not be too tedious. " II That hope is generally realized in Mach's historical writings, most of which are as lively and interesting now as they were when they appeared. Mach did not follow any existing model of historical or philosophical or scientific exposition, but went at things his own way combining the various approaches as needed to reach the goals he set for himself. When he is at his best we get a sense of the Mach whom William James met on a visit to Prague, the Mach whose...

The Law of Causality and its Limits was the principal philosophical work of the physicist turned philosopher, Philipp Frank. Born in Vienna on March 20, 1884, Frank died in Cambridge, Massachusetts on July 21, 1966. He received his doctorate in 1907 at the University of Vienna in theoretical physics, having studied under Ludwig Boltzmann; his sub sequent research in physics and mathematics was represented by more than 60 scientific papers. Moreover his great success as teacher and expositor was recognized throughout the scientific world with publication of his collaborative Die...

Ladislav Tondl's insightful investigations into the language of the sciences bear directly upon some decisive points of confrontation in modern philos- ophy of science and of language itself. In the decade since his Scientific Procedures was published in English (Boston Studies 11), Dr Tondl has enlarged his original monograph of 1966 on the promise, problems and achievements of modern semantics: the main topic of his later work has been semantic information theory. A Russian translation, considerably expanded as a second edition, was published in 1975 (Moscow, Progress Publishers) with an...

Friedrich Waismann was born in Vienna in 1896 and lived there until the time of the Anschluss in 1938. From then until his death in 1959 he lived in England; this, apart from a brief period at Cambridge early on, was almost wholly at Oxford, ,Vhere he held the posts, first, or reader in the philosophy of mathematics and then of reader in the philosophy of science. He was of Jewish descent -his father being Russian, his mother German. He studied mathematics and physics at the University of Vienna and attended the lec- tures of Hahn. Beginning his career as a teacher of mathematics he soon be-...

The main item in the present volume was published in 1930 under the title Das Unendliche in der Mathematik und seine Ausschaltung. It was at that time the fullest systematic account from the standpoint of Husserl's phenomenology of what is known as 'finitism' (also as 'intuitionism' and 'constructivism') in mathematics. Since then, important changes have been required in philosophies of mathematics, in part because of Kurt Godel's epoch-making paper of 1931 which established the essential in completeness of arithmetic. In the light of that finding, a number of the claims made in the book (and...

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...

The nutrient dynamics and biological structure of shallow non-stratified lakes differ markedly from that of deep and stratified lakes: for example, the return of nutrients lost through sedimentation is faster and the potential importance of fish and submerged macrophytes as food-web regulators is greater. In addition shallow lakes are more easily influenced by fluctuations in the physical environment caused by wind disturbance, temperature change, etc. Although shallow lakes are often the most common lake type in lowland countries, less attention has been paid to them than to deep stratified...
