This book takes an idea first explored by medieval logicians 800 years ago and revisits it armed with the tools of contemporary linguistics, logic, and computer science. The idea - the Holy Grail of the medieval logicians - was the thought that all of logic could be reduced to two very simple rules that are sensitive to logical polarity (for example, the presence and absence of negations). Ludlow and Živanović pursue this idea and show how it has profound consequences for our understanding of the nature of human inferential capacities. They also show its consequences for some of the deepest issues in contemporary linguistics, including the nature of quantification, puzzles about discourse anaphora and pragmatics, and even insights into the source of aboutness in natural language. The key to their enterprise is a formal relation they call "p-scope" - a polarity-sensitive relation that controls the operations that can be carried out in their Dynamic Deductive System. They show that with p-scope in play, deductions can be carried out using sublogical operations like those they call COPY and PRUNE - operations that are simple syntactic operations on sentences. They prove that the resulting deductive system is complete and sound. The result is a beautiful formal tapestry in which p-scope unlocks important properties of natural language, including the property of "restrictedness," which they prove to be equivalent to the semantic notion of conservativity. More than that, they show that restrictedness is also a key to understanding quantification and discourse anaphora, and many other linguistic phenomena.

This volume deals with the connection between thinking-and-speaking and our form(s) of life. All contributions engage with Wittgenstein’s approach to this topic. As a whole, the volume takes a stance against both biological and ethnological interpretations of the notion "form of life" and seeks to promote a broadly logico-linguistic understanding instead. The structure of this book is threefold. Part one focuses on lines of thinking that lead from Wittgenstein’s earlier thought to the concept of form of life in his later work. Contributions to part two examine the concrete philosophical function of this notion as well as the ways in which it differs from cognate concepts. Contributions to part three put Wittgenstein’s notion of form of life in perspective by relating it to phenomenology, ordinary language philosophy and problems in contemporary analytic philosophy.

One of the central issues of analytic philosophy and especially the theory of language is the concept of logical form. As typically understood this concept covers investigations into universal logical features underlying languages. However, from Frege and Russell onwards logical form analysts were no longer confined to such narrow linguistic perspectives. For them, investigating the logical form of language took the wider philosophical perspective of trying to understand language as our principal means for representing the world. From Russell's theory of definite descriptions to Davidson's truth-theoretical analyses of adverbial modification, citation, and reported speech, to lay open the logical structures underlying language is seen as a way of revealing the structure and features of the thereby represented world. Seventeen specially written essays by eminent philosophers and linguists appear for the first time in this anthology. Logical Form and Language brings together exciting new contributions from diverse points of view, which illuminate the lively current debate about this topic.

Publisher description

Ricorso and Revelation traces the impact on Modernism of the archaeological discoveries of the Palace of Knossos, the Royal Cemetery of Ur, and the Tomb of Tutankhamen, and the artifacts recovered from these sites, showing how they entered the narrative strategies of the Modernist movement. The author also develops a new argument about the four myth configurations — the maze, alchemy, the Great Goddess, and the Apocalypse — which were of central importance to the literature of European Modernism between 1895 and 1946, studying their appearances in a wide range of European modernist writers and in the paintings of Picasso and the films of Jean Cocteau. Drawing from a variety of theories on myth, Smith suggests that each of these four myths represents a creative return to the origins (ricorso), a reduction of the raw materials of daily life to the fundamental elements of creation (revelation), followed by a recreation of the world (cosmogenesis), of the poet (ontogenesis), and of the text (poesis).

This book constitutes the refereed proceedings of the 22nd Annual German Conference on Artificial Intelligence, KI-98, held in Bremen, Germany, in September 1998. The 16 revised full papers presented were carefully reviewed and selected for inclusion in the proceedings. Also included are three invited papers and abstracts of two invited talks, as well as an appendix containing up-to-date descriptions of German AI projects. Thus the volume gives a unique overview of AI research in Germany.
