Charles Sanders Peirce (1839--1914) has often been referred to as one of the most important North American philosophers, but the real extent of his philosophical importance is only now beginning to emerge. Peirce's pragmaticism' (his own term) may provide the key to an epistemological theory which avoids both the Scylla of foundationalism and the Charybdis of relativism. Peirce's Logic', linked to a conception of knowledge and of science, is increasingly coming to be recognised as the only possible one. In Living Doubt, 26 papers are presented by some of the world's leading philosophers, demonstrating the rich and cosmopolitan variety of approach to Peirce's epistemology. The contributions are grouped under three general headings: Knowledge, truth and the pragmatic principle; Peirce and the epistemological tradition; and Knowledge, language and semeiotic.

This volume contains the Proceedings of the International Colloqui- um "Newton's Scientific and Philosophical Legacy", that was held at the Catholic University of Nijmegen (The Netherlands) from June 9th to 12th 1987 to celebrate the Tercentenary of the publication of Newton's Philo- sophiae Naturalis Principia Mathematica (1667). Although 1987 was a busy year for Newton scholars, we were happy that five of most prom- inent among them were able to come to Nijmegen and speak on the vari- ous aspects of Newton's thought. They are the Professors I. Bernard Cohen (Harvard), Gale Christianson (Indiana State), B. J. Dobbs (Northwestern), Richard H. Popkin (UCLA) and Mordechai Feingold (Boston University). No doubt, recent scholarship has put Newton's genius in a quite different perspective from the one that had come to make up what may be called Newtonian mythology. Although his achievements in the areas of mechanics, mathematics, and optics remain indisputed, Newton's scientific efforts were apparently entirely subordi- nate to his religious beliefs. This volume has been divided into four parts, preceded by a Pream- ble in which Prof. Christianson offers a vivid portrait of Newton as a per- son. The first part deals with the science of Newton as he himself under- stood that term. The second part considers the influence of Newton's work on later scientific developments. The third part deals primarily with the question of the methodological influence of Newton, and the last part with his more philosophical legacy. Two editorial remarks are due.
