Seventeen specially written essays by eminent philosophers and linguists appear for the first time in this anthology, all with the central theme of logical form - a fundamental issue in analytical philosophy and linguistic theory.
Logical form has always been a prime concern for philosophers belonging to the analytic tradition. For at least one century, the study of logical form has been widely adopted as a method of investigation, relying on its capacity to reveal the structure of thoughts or the constitution of facts. This book focuses on the very idea of logical form, which is directly relevant to any principled reflection on that method. Its central thesis is that there is no such thing as a correct answer to the question of what is logical form: two significantly different notions of logical form are needed to fulfill two major theoretical roles that pertain respectively to logic and to semantics. This thesis has a negative and a positive side. The negative side is that a deeply rooted presumption about logical form turns out to be overly optimistic: there is no unique notion of logical form that can play both roles. The positive side is that the distinction between two notions of logical form, once properly spelled out, sheds light on some fundamental issues concerning the relation between logic and language.
Logical Form in Natural Language clearly explains and defends the truth-theoretic method in semantics first developed by Donald Davidson to analyze logical forms of sentences of natural language.
This study focuses on the relation of syntactic and semantic structure. It investigates the notion that within generative grammar there is a level of linguistic representation Logical Form. Its main assumption is that this is a level of phrase structure representation, derived by transformational operations from S-structure, and over which formal semantic interpretations are defined.The book explores Logical Form by focusing primarily on quantificational phenomena and on how their explicit syntactic representation interacts with various syntactic and semantic properties. Among the topics discussed are the interactions of wh and quantified phrases, bound variable anaphora, branching quantifiers, extraposition and multiple interrogation.Logical Form contains several technical innovations: the notion that LF-movement closely approximates "Move α," a new approach to characterizing quantifier scope, which makes central use of the notion of "government," a novel interpretation of the relation of syntactic nodes and categorical projections, and an application of path theory to the syntactic structure of Logical Form.Robert May is Assistant Professor of Linguistics, Barnard College, Columbia University.

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.
Directionality and Logical Form provides a detailed treatment of the syntax of focusing particles, such as only and even in a cross-linguistic perspective. The derivation of logical forms is shown to be under the control, not only of the ECP and subjacency, but also of directionality of government and the particular word-order parameter that holds in a given language: head-final languages systematically disallow certain derivations or readings that are available in head-initial languages. The reason is that heads that deviate in their selection properties from canonical head-finality project a directionality barrier. Various strategies are explored by which this barrier can be circumvented. Although the theory is developed mainly on the basis of the head position in German, it can be directly used to explain constraints on the scope of Wh-in-situ in Bengali and closely related languages. Audience: Syntacticians and semanticists interested in parametric variation, as well as linguists working on Germanic and/or Indo-Aryan languages.
This book critically reviews grammatical research into logical form over the past 20 years and reconsiders some of its major themes in the light of recent theoretical innovations. In the late 1970s generative grammarians proposed the existence of an abstract syntactic level of grammatical representation derived from surface structure which was phonetically invisible. This level, dubbed logical form, has been thought of as the information that the grammar contributes to semantic interpretation. The first part of the book reviews the standard arguments for the existence of LF and its format.
Lexico-Logical Form relates in aim to Noam Chomsky's recent works on economy and minimalism: both authors recast the structure of the grammar, revealing its essential properties in the process. In Lexico- Logical Form, Michael Brody meticulously dissects aspects of the Principles and Parameters theory, pares away the extraneous, focuses on core issues, and recreates them in subtle and interesting ways.Brody argues for and discusses aspects of a radically minimalist, nonderivational approach to syntax in which both the central conceptual systems and the lexicon have direct access to the single syntactic representation, called Lexico-Logical Form. He proposes to streamline the syntactic component of the grammar by eliminating syntactic derivation and all syntactic levels of representation other than LF, the interface with the semantic component.A central driving force throughout is the elimination of redundancy in the theory. Since movement characterizes a subset of the relations characterized by chains, the former is eliminated. Since the lexicon must constrain the input to the semantic component, intervening representations are eliminated, and the relationship beween the lexicon and LF becomes direct. This timely approach explores a logical next step in the minimalist path.Lingistic Inquiry Monograph No. 27
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.
