A collection of papers from Paul Hertz to Dov Gabbay - through Tarski, Gödel, Kripke - giving a general perspective about logical systems. These papers discuss questions such as the relativity and nature of logic, present tools such as consequence operators and combinations of logics, prove theorems such as translations between logics, investigate the domain of validity and application of fundamental results such as compactness and completeness. Each of these papers is presented by a specialist explaining its context, import and influence.

From the reviews:“The quest for common ground in the expression of logical statements--regardless of the given syntax, semantics, or grammar--has taken the best efforts of notable logicians throughout the 20th century. This book gathers a collection of some of the most notable of their works. Its structure is chronological … . I highly recommend this book to logicians, mathematicians working on provability theory, and software engineers.” (Arturo Ortiz-Tapia, ACM Computing Reviews, July, 2012)

No other anthology on universal logic or connected topics has been published In general it is not so usual to have an anthology with presentations of each paper by so many different specialists In this book will be collected already published papers from 1920 to 1990 that can be considered in the spirit of universal logic Includes supplementary material: sn.pub/extras
