Over the objective of questioning the epistemic foundation of the governance notion, we aim to resituate it in a sociological reality as much theoretical as empirical. This thought found its roots inside the modern condition, for which following Touraine (1992), joins together Reason and Subject. Consequently, the modern individual take part in an emerging political culture built on the basis of individualism where Subject can pretend to be part in res publica. Governance seems to allow that new political culture. In order to explore these ideas, a case study will be presented around two fields in Bas-Saint-Laurent area (Québec) where two populations are engaged in developing a collective project linking economic and social matter while integrating the protection of natural resources; the French tool Parc National Régional is evaluated. Taking those results as a starting point we note that the passage between systems of political actions whose standards are well established and to a political tool like governance runs up against different principles of action.
