Revisiting the Circular Nature of a Research Path

In this paper, I recall some moments of my intellectual journey and some of the people who have played an important role in my development. Moreover, I give a survey of the various lectures delivered at the symposium with the purpose of highlighting the ideas they share, how the ideas were developed and how they have been aggregated together so as to become a basis for reflection for the Saint-Denis cognitive psychology group and for researchers and students interested in this approach.
