Logic and Philosophy of Logic

Logic and philosophy of logic have increasingly become areas of research and great interest in Latin America and Spain where significant work has been done and continues to be done in both of these fields. The goal of this volume is to draw attention to this work through a collection of original and unpublished papers by specialists from Latin America and Spain.Some of the papers are of importance for set-theory and model theory. They cover topics such as the foundations of paraconsistency the use of paraconsistent logic as a basis for set-theory and the methodological aspects in both the justi?cation of new axioms in set theory and the formalization of pre-theoretic notions. Other papers are related to epistemic logic. They deal with the issues of abduction and the choice of the simplest hypothesis the definition of group probability and the nature of explanation and understanding in such logic. There are also papers on logical paradoxes the semantics of names (including fictional names) and the nature of relations.Max A.
