This volume is a valuable addition to the literature related to the Soviet invasion of Czechoslovakia in August 1968. The author focusses his analysis on the facotrs that determined the post-invasion "normalization" primarily in terms of the Czechoslovak response to the invasion which imparted a specific character to the aftermath of the action of the Warsaw Pact.

During the late 1960s, Normalization and Social Role Valorization (SRV) enabled the widespread emergence of community residential options and then provided the philosophical climate within which educational integration, supported employment, and community participation were able to take firm root. This book is unique in tracing the evolution and impact of Normalization and SRV over the last quarter-century, with many of the chapter authors personally involved in a still-evolving international movement. Published in English.

This volume presents an illuminating analysis of the ways in which normalization processes and practices operate in a welfare state in an age of neoliberalism. This informative book problematizes the meaning of the phrase 'normalization processes and prac

An Introduction to Proof Theory provides an accessible introduction to the theory of proofs, with details of proofs worked out and examples and exercises to aid the reader's understanding. It also serves as a companion to reading the original pathbreaking articles by Gerhard Gentzen. The first half covers topics in structural proof theory, including the Gödel-Gentzen translation of classical into intuitionistic logic (and arithmetic), natural deduction and the normalization theorems (for both NJ and NK), the sequent calculus, including cut-elimination and mid-sequent theorems, and various applications of these results. The second half examines ordinal proof theory, specifically Gentzen's consistency proof for first-order Peano Arithmetic. The theory of ordinal notations and other elements of ordinal theory are developed from scratch, and no knowledge of set theory is presumed. The proof methods needed to establish proof-theoretic results, especially proof by induction, are introduced in stages throughout the text. Mancosu, Galvan, and Zach's introduction will provide a solid foundation for those looking to understand this central area of mathematical logic and the philosophy of mathematics.

The functional logic programming paradigm combines the two most important fields of declarative programming, namely functional and logic programming, in an integrated way to allow the concise notation of high-level programs. However, the variety of concepts and conciseness of programs may also impact their efficiency. In this work we employ the powerful optimization technique of partial evaluation to develop a fully automatic program optimizer, the so-called partial evaluator. In particular, we formalize the normalization of programs during compilation, establish a formal notation of the evaluation process, develop a formal partial evaluation scheme and prove its correctness and termination, and implement a working partial evaluator which shows impressive results.

This introduction to the basic ideas of structural proof theory contains a thorough discussion and comparison of various types of formalization of first-order logic. Examples are given of several areas of application, namely: the metamathematics of pure first-order logic (intuitionistic as well as classical); the theory of logic programming; category theory; modal logic; linear logic; first-order arithmetic and second-order logic. In each case the aim is to illustrate the methods in relatively simple situations and then apply them elsewhere in much more complex settings. There are numerous exercises throughout the text. In general, the only prerequisite is a standard course in first-order logic, making the book ideal for graduate students and beginning researchers in mathematical logic, theoretical computer science and artificial intelligence. For the new edition, many sections have been rewritten to improve clarity, new sections have been added on cut elimination, and solutions to selected exercises have been included.

by MICHEL FOUCAULT Everyone knows that in France there are few logicians but many historians of science; and that in the 'philosophical establishment' - whether teaching or research oriented - they have occupied a considerable position. But do we know precisely the importance that, in the course of these past fifteen or twenty years, up to the very frontiers of the establishment, a 'work' like that of Georges Canguilhem can have had for those very people who were separ ated from, or challenged, the establishment? Yes, I know, there have been noisier theatres: psychoanalysis, Marxism, linguistics, ethnology. But let us not forget this fact which depends, as you will, on the sociology of French intellectual environments, the functioning of our university institutions or our system of cultural values: in all the political or scientific discussions of these strange sixty years past, the role of the 'philosophers' - I simply mean those who had received their university training in philosophy department- has been important: perhaps too important for the liking of certain people. And, directly or indirectly, all or almost all these philosophers have had to 'come to terms with' the teaching and books of Georges Canguilhem. From this, a paradox: this man, whose work is austere, intentionally and carefully limited to a particular domain in the history of science, which in any case does not pass for a spectacular discipline, has somehow found him self present in discussions where he himself took care never to figure.
