Résumé
This study's aim is to prove that putting in place of a real philosophical work with children is possible and can be made easier if they are allowed in their forms to express a personal thought. That is where among other things the co-operative pedagogy lead to. It will then consist in emphasizing that the practise of cooperation at school can be continued and completed thanks to a meeting with the philosopher. These stakes appear to be stronger since we also propose to show how children of a school located in a Priority Education Area, who are most of the time of Maghrebi extraction, are capable of philosophizing. A varied methodological corpus includes a series of scripts of philosophical discussions of a third course form during three years, of discussions with pupils, with teachers and with people recognized as experts on these fields, of questionnaires filled out by all the pupils of a co-operative school in Montpellier.
