In his writings on the foundations of logic, Gottlob Frege, the father of modern logic, sketched a conception of truth that focuses on the following questions: What is the sense of the word "true"? Is truth a definable concept or a primitive one? What are the kinds of things of which truth is predicated? What is the role of the concept of truth in judgment, assertion and recognition? What is the logical category of truth? What is the significance of the concept of truth for science in general and for logic in particular?
The present volume is dedicated to the interpretation, reconstruction and critical assessment of Frege's conception of truth. It is of interest to all those working on Frege, the history of logic and semantics, or theories of truth. The volume brings together nine original papers whose authors are all widely known to Frege scholars. The main topics are: the role of the concept of truth in Frege's system, the nature of the truth-values, the logical category of truth, the relationship between truth and judgment, and the conception of the truth-bearers.
Dirk Greimann received his doctorate from the University of Munich and is now Professor of Philosophy at the Federal University of Santa Maria in Brazil. His areas of specialization are the philosophy of language and logic, ontology, and the history of Analytic Philosophy, especially Frege, Tarski and Quine. He has extensively published in these areas and is currently working on a book dealing with the relationship between truth and assertoric force.
