The Square : a Central Object for Thought
The square of opposition is a very famous theme coming from Aristotelian logic dealing with the notions of opposition, negation, quantification and proposition. It has been continuously studied by people interested in logic, philosophy and Aristotle during two thousand years. Even Frege, one of the main founders of modern mathematical logic, used it.
Some people have proposed to replace the square by a triangle, on the other hand the square has been generalized into more complex geometrical objects: hexagons, octagons and even polyhedra and multi-dimensional objects.
Aim of the Congress
This will be the 3rd world congress organized about the square of opposition after very succesful previous events in Montreux, Switzerland 2007 and in Corté, Corsica 2010. This is an interdisciplinary event gathering logicians, philosophers, mathematicians, semioticians, artists, cognitivists, and computer scientists.
The meeting will end by a final round square table where subalterned people will express their various contrarieties, subcontrarieties and contradictions.
