This will be the 6th world congress organized about the square of opposition after very successful previous editions in Montreux, Switzerland 2007; Corté, Corsica 2010; Beirut, Lebanon 2012; Vatican, 2014; Easter Island, 2016. This is an interdisciplinary event gathering logicians, philosophers, mathematicians, semioticians, theologians, cognitivists, artists and computer scientists.

The square of opposition is a logical structure coming from Aristotelian logic. It has been continuously studied during two thousand years. Even Frege, one of the main founders of modern mathematical logic, used it. It can be applied to many fields, ranging from metalogic to highway code, through economics, music, physics, color theory, theology.
