Jean-Blaise Grize will always be one of the most important logicians in the world. His studies have been providing fondamental contributions to genetic epistemology and argumentation studies. As Emeritus Professor of the University of Neuchâtel, he worked on epistemology, logic and psycholinguistics. He conceived natural logic as a logic field and, in this endeavour, counted on the collaboration of Marie-Jeanne Borel and Professor Denis Miéville who inherited his Chair and the direction of his research centre. Professor Grize passed away on the 3rd August 2013.

NATURAL LOGIC
Natural logic was developed with the goal of expressing the logic of thinking processes. It allows the researcher to analyze representations that are generated by mental operations while people communicate. In addition to its philosophical and epistemological foundations, natural logic was conceived as a tool able to go beyond the Piagetian model of operatory logic. It is a suitable method to study of communication situations. For additional information, visit the website of Communalis - Communication and Natural Logic International Society.
