We present in this article a new logical system inspired from linear logic. This system is designed in order to express causality and dynamism. The cut elimination theorem holds for this logic. Examples of applications are given.

John B. Thompson's lucid and helpful introduction to this collection of essays includes a brief history of Ricoeur's career and the thematic focuses of his major works. This introduction is followed by "Notes on editing and translating" and by "A Response by Paul Ricoeur.".

This volume "contains eight articles dealing with the intellectual and institutional developments in physics from the mid-1840’s to the mid-1920’s. The primary focus is on the quantum and relativity theories and Einstein’s contributions to these theories. The secondary focus is on thermodynamics and its kinetic theory basis in the nineteenth century." Slightly more than one third of the book is devoted to various aspects of Einstein’s work: M. J. Klein analyzes his difference with Bohr in 1923-1925; R. McCormmach traces the (...) problem area which he extracted from Lorentz’ electron theory in about the first decade of this century; and S. Goldberg considers the British response to his special theory of relativity in 1905-1911. In the editor’s foreword, McCormmach illustrates from the current investigation of Einstein a general thesis about "the limitations of contemporary writing in the history of science." Thus, this anthology may well become a standard secondary source for Einstein scholarship. A fourth of the book has to do with thermodynamics: Y. Elkana follows Helmholtz’ formulation of its first law ; E. E. Daub looks at the evolution of concepts essential to its second law ; and E. W. Garber delineates Clausius’ contribution to its underpinnings. Just two articles are unrelated to these two foci: P. Forman, in the longest paper in the volume, considers Lande’s search for a theory of the anomalous Zooman effect in 1919-1921; and R. Sviedrys, in an exchange with A. Thackray, examines the rise of physical science at Cambridge University during the Victorian era. (shrink)

Taking the position that scientific hypotheses explain the world and do not merely classify data, the author describes the decline of the Newtonian world picture and the development of a new, "ether-theoretical" view. The nineteenth century founders of electromagnetism—Faraday, Maxwell, Hertz, Lorentz—all tendered theories of a medium, usually called the "ether," which filled the space between any two noncontiguous bodies and transported electromagnetic actions from one to the other. After Einstein profoundly reinterpreted the concept of medium, it came to be (...) called the "field." In giving this history, William Berkson explains what problems each scientist faced and how the process of solving them led to new discoveries. He also draws out the philosophical consequences of the history, especially for the positions of Popper, Meyerson, Agassi and Kuhn. (shrink)

This massive, expensive tome comprises all the proceedings of the 1970 biennial meeting of the Philosophy of Science Association. Beyond the selection of the papers to be presented at the meeting, there has been no winnowing of the good from the bad. Further, there is no indexing. Thus, the technical philosopher of science, to whose interest the contributed papers in this anthology will appeal, faces the prospect of doing these jobs himself. The symposium papers, which account for a relatively small (...) fraction of this volume, will interest readers of this journal the most. These papers investigate three topics: theoretical entities in statistical explanation; capacities and natures; history of science and its rational reconstruction. (shrink)

While cetaceans clearly show social learning in a wide variety of contexts, to label this as hides more than it reveals: we need a taxonomy of culture to tease apart the differences rather than hiding them in a catch-all category.

In recent years, most studies of human memory systems have placed the emphasis on differences rather than on similarities. The present study sought to assess the impact of perceptual priming on the creation of new episodic memories. It was composed of three distinct experimental phases: an initial study phase, during which the number of repetitions of target words was manipulated; a perceptual priming test phase, involving both target and new control words, which constituted the incidental encoding phase of a subsequent (...) Remember/Know/Guess recognition task. Results showed that the greater the perceptual priming at encoding, the more the episodic memory performance was enhanced, whereas no such relation was found for know judgments or feeling of familiarity. Furthermore, the words that were associated with the creation of new episodic memories had been perceptually primed to a greater extent during the incidental encoding phase than the words that were subsequently judged to be known or forgotten. These results suggest that the perceptual contents of episodic memories are constituted by the very perceptual representations that generate priming effects. Potential mechanisms linking perceptual priming to the creation of episodic memories are discussed. (shrink)
