This SAJL will promote interaction among logicians based in South America and also between logicians from South America and logicians from other continents. The aim of the South American Journal of Logic is to promote logic in all its aspects: philosophical, mathematical, computational, historical by publishing high quality peer-reviewed papers. You are welcome to submit a paper. Send your paper in PDF to: submit@sa-logic.org. Editors-in-Chief.
