In this 1958 book, Professor Hanson turns to an equally important but comparatively neglected subject, the philosophical aspects of research and discovery.

A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

The essays in this volume represent an approach to human knowledge that has had a profound influence on many recent thinkers. Popper breaks with a traditional commonsense theory of knowledge that can be traced back to Aristotle. A realist and fallibilist, he argues closely and in simple language that scientific knowledge, once stated in human language, is no longer part of ourselves but a separate entity that grows through critical selection.

Mr. Danto argues that recent developments in the artworld, in particular the production of works of art that cannot be told from ordinary things, make urgent the need for a new theory of art and make plain the factors such a theory can and cannot involve. In the course of constructing such a theory, he seeks to demonstrate the relationship between philosophy and art, as well as the connections that hold between art and social institutions and art history. The book (...) distinguishes what belongs to artistic theory from what has traditionally been confused with it, namely aesthetic theory and offers as well a systematic account of metaphor, expression, and style, together with an original account 0f artistic representation. A wealth of examples, drawn especially from recent and contemporary art, illuminate the argument. (shrink)

Coherent, well organized text familiarizes readers with complete theory of logical inference and its applications to math and the empirical sciences. Part I deals with formal principles of inference and definition; Part II explores elementary intuitive set theory, with separate chapters on sets, relations, and functions. Last section introduces numerous examples of axiomatically formulated theories in both discussion and exercises. Ideal for undergraduates; no background in math or philosophy required.

This second edition features a new 48-page Afterword--1980 updating Professor Beardsley's classic work.

This is the basis of the first part of the book.

In the present paper Cohen's and Lee's theory of social conformity and Festinger's theory of cognitive dissonance are first reconstructed according to a revised form of the so-called “structuralist theory-conception” developed by Sneed and Stegmüller with their collaborators. Then the two theories are conceptually correlated in the sense of a technical notion of conceptual correlation which can be shown to be an essential generalization of the theory-relations handled by the structuralist. It will turn out that there is no unique way (...) to connect these theories with each other. However, it is shown that two ontologically and conceptually different theories can be correlated. This in turn gives in principle an opportunity to compare critically these two theories given that the constructed conceptual correlation is sufficiently sound and that the theories are empirically testable to a sufficient extent.

We revive the idea that a deductive-nomological explanation of a scientific theory by its successor may be defensible, even in those common and troublesome cases where the theories concerned are mutually incompatible; and limiting, approximating and counterfactual assumptions may be required in order to define a logical relation between them. Our solution is based on a general characterization of limiting relations between physical theories using the method of nonstandard analysis.

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 round this issue in my studies of intertheory relations in science, I decided to take the plunge and make the problem of incommensurability the central and unifying theme of a book. The present volume is the result of that decision. My interest in problems of comparability and commensurability in science was awakened in the formative years of my philosophi cal studies by my teacher, Jerzy Giedymin. From him I have learnt not only to enjoy philosophical problems but also to beware of simpleminded solutions to them. The vibrant seminars of Paul Feyerabend held at Sussex University in 1974 left me in no doubt that incommensurability was, and would remain, a major topic of debate and dispute in the philosophical study of human knowledge.
