This is the second edition of an important introduction to Leibniz's philosophy of logic and language first published in 1972. It takes issue with several traditional interpretations of Leibniz (by Russell amongst others) while revealing how Leibniz's thought is related to issues of great interest in current logical theory. For this new edition, the author has added new chapters on infinitesimals and conditionals as well as taking account of reviews of the first edition.

Second edition of an important introduction to Leibniz"s philosophy of logic and language, first published in 1972.

The most comprehensive account of the full range of Leibniz's thought.

Why was Leibniz so deeply interested in signs and language? What role does this interest play in his philosophical system? In the essays here collected, Marcello Dascal attempts to tackle these questions from different angles. They bring to light aspects of Leibniz's work on these and related issues which have been so far neglected. As a rule they take as their starting point Leibniz's early writings (some unpublished, some only available in Latin) on characters and cognition, on definition, on truth, on memory, on grammar, on the specific problems of religious discourse, and so on. An effort has been made to relate the views expressed in these writings both to Leibniz' more mature views, and to the conceptions prevailing in his time, as well as in preceding and following periods. The common thread running through all the essays is to what extent language and signs, in their most varied forms, are related to cognitive processes, according to Leibniz and his contemporaries.

Language is what we all share and is our common concern. What is the nature of language? How is language related to the world? How is communication possible via language? What is the impact of language on our reasoning and thinking? Many people are unaware that misunderstandings and conflicts during communication occur as a result of the way we use language. This book introduces the central issues in the history of philosophical investigations about the concept of language. Topics are structured with reference to the world’s foremost philosophers of language. The book will encourage the reader to explore the depths of the concept of language and will raise an awareness of this distinctive human capacity.

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.

Translations of some of Leibniz's most important logical works. A long introduction provides explanatory comment and gives an estimate of Leibniz as a logician.
