In the fall of 1985 Carnegie Mellon University established a Department of Philosophy. The focus of the department is logic broadly conceived, philos- ophy of science, in particular of the social sciences, and linguistics. To mark the inauguration of the department, a daylong celebration was held on April 5, 1986. This celebration consisted of two keynote addresses by Patrick Sup- pes and Thomas Schwartz, seminars directed by members of the department, and a panel discussion on the computational model of mind moderated by Dana S. Scott. The various contributions, in modified and expanded...

The Lvov-Warsaw School was active in all spheres of philosophy. Its members worked in the border area between philosophy and disci- plines such as psychology, linguistics, and literary theory. But its most important achievements were without doubt in logic and philosophical analysis based on logic. The present book is concerned with fields to which the Lvov-Warsaw School made its most important and famous contributions. Data on the School as a whole are included only in the first and last part of the book. This work is based on my monograph (1985), which appeared in Polish. But it is not...

This is not "another collection of contributions on a traditional subject." Even more than we dared to expect during the preparatory stages, the papers in this volume prove that our thinking about science has taken a new turn and has reached a new stage. The progressive destruction of the received view has been a fascinating and healthy experience. At present, the period of destruction is over. A richer and more equilibrated analysis of a number of problems is possible and is being cru'ried out. In this sense, this book comes right on time. We owe a lot to the scholars of the Kuhnian period....

1. The Aim of This Essay Ethical Egoism, the doctrine that, roughly speaking, one should promote one's own good, has been a live issue since the very beginnings of moral philosophy. Historically, it is the most widely held normative theory, and, next to Utilitarianism, it is the most intensely debated one. What is at stake in this debate is a fundamental question of ethics: 'Is there any reason, except self-interest, for considering the interests of other people?' The ethical egoist answers No to this question, thus rejecting the received conception of morality. Is Ethical Egoism an...

Probability has become one of the most characteristic con cepts of modern culture, and a 'probabilistic way of thinking' may be said to have penetrated almost every sector of our in tellectual life. However it would be difficult to determine an explicit list of 'positive' features, to be proposed as identifica tion marks of this way of thinking. One would rather say that it is characterized by certain 'negative' features, i. e. by certain at titudes which appear to be the negation of well established tra ditional assumptions, conceptual frameworks, world outlooks and the like. It is because...

The modern discussion on the concept of truthlikeness was started in 1960. In his influential Word and Object, W. V. O. Quine argued that Charles Peirce's definition of truth as the limit of inquiry is faulty for the reason that the notion 'nearer than' is only "defined for numbers and not for theories." In his contribution to the 1960 International Congress for Logic, Methodology, and Philosophy of Science at Stan ford, Karl Popper defended the opposite view by defining a compara tive notion of verisimilitude for theories. was originally introduced by the The concept of verisimilitude...

How many miles to Babylon? Three-score and ten. Can I get there by candle-light? Yes, and back again. If your heels are nimble dnd light, You may get there by candle-light. Any philosopher who takes more than a fleeting interest in the sciences and their development must at some stage confront the issue of incommensurability in one or other of its many manifes tations. For the philosopher of science concerned with problems of conceptual change and the growth of knowledge, matters of incommensurability are of paramount concern. After many years of skating over, skimming through and skirting...

This volume has its already distant or1g1n in an inter national conference on Evolutionary Epistemology the editors organized at the University of Ghent in November 1984. This conference aimed to follow up the endeavor started at the ERISS (Epistemologically Relevant Internalist Sociology of Science) conference organized by Don Campbell and Alex Rosen berg at Cazenovia Lake, New York, in June 1981, whilst in jecting the gist of certain current continental intellectual developments into a debate whose focus, we thought, was in danger of being narrowed too much, considering the still...

Phenomenology and analytic philosophy have skirmished often, but seldom in ways conducive to dialectical progress. Generally, the skirmishes seem more "political" than philosophical, as when one side ridicules the methods of the other or criticizes the viability of the other's issues and assump tions. Analytic interest in third person objectivity is often spurned by Continental philosophers as being unduly abstract. Continental interest in first person subjectivity is often criticized by analysts as being muddled and imprecise. Logical analysis confronts the power of metaphor and judges it...
