In order to determine whether two participants in a discussion are in real dis/agreement, one must compare their propositions. Comparison presupposes yardsticks in common. This text thematises such yardsticks, in that it demonstrates the existence, content and factual significance of a relatively well-delimited set of proposition types and proposition patterns, with their accompanying tenability criteria and motivating interests. The book is a work in the field of legal theory by virtue of its demonstrating how lawyers' power of judgement is constituted in and through these yardsticks. The book is interdisciplinary by virtue of its demonstrating how the same yardsticks come into play more generally in argumentation formulated in everyday language, i.e. independently of law. And the book is a work in the field of philosophy by virtue of its demonstrating the existence and factual significance of language and argumentation actions with a certain independence in relation to the level of controversial fundamental philosophical positions.;""Analysis of Dis/agreement"" is addressed to all who are interested in the mapping of the argumentative structures of language: philosophers, legal theorists, lawyers, linguists and others.
