This paper is devoted to stress the importance of the contribution of Gaetano Kanizsato contemporary psychology. His theoretical ideas have in many respects been truly seminal. In particular, are emphasized his distinction between the primary and secondary process, his criticism of the concept ofPrägnanz, and his focus on self-organisation in a dynamic approach. To continue his work, the main task is to identify the rules and constraints that enable us to see the world as it appears. In the last years of his scientific work, his insight was that the non-linear dynamic approach may be the best way to achieve this goal, giving a more sound sense to the intuitions of Gestalt psychologie.Unfortunately, he died before he could reap the fruits of this insight. Here are reviewed the first results that some among his direct and indirect pupils have obtained in this direction.
