This theoretical study starts from the observation that nearly any social problem is hierarchically structured. In order to elucidate the importance of this hierarchical aspect for the eventual solution of the problem, the concepts «problem domain» and «context» are introduced. With respect to each problem the nature of the problem defining instance, the problem definition and the problem experience are considered under a double aspect: the three of them can be individual as well as collective. As for the problem itself a distinction is made between a subjective and an objective component. One also examines the elements that make a problem into a real social problem. Eventually one observes that each problem situation leads to the formation of a «field of power» involving various problem defining instances, each with its particular problem definition and problem experience. A valuable solution to any problem can hardly be reached without taking into account each of the forces in this field of power.
