This book is the first systematic analysis of the emergence of, and the resolution strategies for, inconsistency in linguistic theorizing.

The question of what types of data and evidence can be used is one of the most important topics in linguistics. This book is the first to comprehensively present the methodological problems associated with linguistic data and evidence. Its originality is twofold. First, the authors' approach accounts for a series of unexplained characteristics of linguistic theorising: the uncertainty and diversity of data, the role of evidence in the evaluation of hypotheses, the problem solving strategies as well as the emergence and resolution of inconsistencies. Second, the findings are obtained by the application of a new model of plausible argumentation which is also of relevance from a general argumentation theoretical point of view. All concepts and theses are systematically introduced and illustrated by a number of examples from different linguistic theories, and a detailed case-study section shows how the proposed model can be applied to specific linguistic problems.

Currently, one of the methodological debates in linguistics focuses on the question of what kinds of data are allowed in different linguistic theories and what subtypes of data can work as evidence for or against particular hypotheses. The first part of the volume puts forward a methodological framework called the ‘p-model’ that is expected to account for the data/evidence problem in linguistics. The aim of the case studies in the second part is to show how this framework can be applied to the everyday research practice of the working linguist, and how it can increase the effectiveness of linguistic theorising. Accordingly, the case studies exemplify that the p-model can come to grips with diverse object-scientific quandaries in syntax, semantics and pragmatics. The third part includes case studies that illustrate how it copes with metascientific issues such as inconsistency in linguistic theories and the relationship between thought experiments and real experiments.

Although the past decades have seen a great diversity of approaches to the history of generative linguistics, there has been no systematic analysis of the state of the art. The aim of the book is to fill this gap. Part I provides an unbiased, balanced and impartial overview of numerous approaches to the history of generative linguistics. In addition, it evaluates the approaches thus discussed against a set of evaluation criteria. Part II demonstrates in a case study the workability of a model of plausible argumentation that goes beyond the limits of current historiographical approaches. Due to the comprehensive analysis of the state of the art, the book may be useful for graduate and undergraduate students. However, since it is also intended to enrich the historiography of linguistics in a novel way, the book may also attract the attention of both linguists interested in the history of science, and historians of science interested in linguistics.

The present books is a step further in the theoretical definition of the ROAL-Hypothesis, in which new empirical and experimental dimensions and findings encounter a space hypothesis of language and language-in-individual-languages. The space hypothesis has been a necessary mode to strengthen mathematical postulates on text/field levels between verifiability/demonstration and events of individual languages. In addition to past books, the present one discusses two difficult questions: - Demonstration of translatability - The relation between the linguistic object and it's semiotic projection. Both face the challenge of immanence/relevance from both epistemic and mathematical modelling. The result as such derives from a constant search of a scientific theory of language accounting for verifiability/demonstration and empirical observability beyond idealizations and idealization raising lacking complex relations between acts and facts.

This book investigates a large range of changes and their motivations in all parts of the grammar and lexicon. The core argument is that, in the absence of a Grand Unification Theory in linguistics, a natural language changes. Changes occur in successive formal grammars.

The evaluation of linguistic theories depends heavily on what kind of data can be regarded as evidence either for or against their hypotheses. The question of what data types linguistic theories use, and which of these types are acknowledged as evidence, is accordingly one of the most fundamental and most widely discussed problems of contemporary linguistics. The aim of this volume is to shed fresh light on this problem by presenting the first findings of a research project. Part I consists of state-of-the-art studies critically analysing current views on the topic. Part II includes case studies which highlight how the conclusions of the state-of-the-art studies may motivate novel and sophisticated accounts of the particular linguistic issues investigated. Die Bewertung linguistischer Theorien hängt in einem bedeutenden Maße davon ab, welche Datentypen als Evidenz für oder gegen ihre Hypothesen herangezogen werden. Die Frage, welche Datentypen linguistische Theorien verwenden und welche von diesen als Evidenz gelten, ist dementsprechend eines der schwerwiegendsten und meistdiskutierten Grundlagenprobleme der gegenwärtigen Linguistik. Dieser Band setzt sich zum Ziel, durch die Darstellung der ersten Resultate eines Forschungsprojekts neues Licht auf dieses Problem zu werfen. Teil I besteht aus Forschungsüberblicken, die sich mit jüngsten Ansichten kritisch auseinandersetzen. Teil II enthält Fallstudien, die illustrieren sollen, auf welche Weise die Ergebnisse der Forschungsüberblicke neuartige und ausgefeilte Analysen der jeweiligen linguistischen Erscheinungen motivieren.
