Resonance is a quality of human relationships with the world proposed by Hartmut Rosa. Rosa, professor of sociology at the University of Jena, uses his resonance theory in Resonanz (2016) to explain social phenomena from a fundamental human quest for "resonant" relationships. Resonance term The term resonance is taken from physics to describe a subject–object relationship as a vibrating system in which both sides mutually stimulate each other. In contrast to the physical meaning of the word, however, here they do not merely return the received sound, but speak "with their own voice". The subjects' relational abilities and their intersubjective structures are constituted by such resonance experiences or their absence. This is made clear by the primary relationship of the newborn to its reference person, by whose reception or rejection of interactions the fundamental relationship patterns develop. With the concept of resonance used in this way, an attempt is made to find a way of approaching the question of successful relations between subject and world in the sense of "good life" as free as possible from cultural evaluations and assumptions. The possible points of reference of such resonances are ubiquitous and are described in three basic axes: Horizontal resonances take place between two (or more) people, in love and family relationships, friendships or political space. Diagonal resonance axes are relationships to things and activities, vertical resonance axes are relationships to the great collective singulars: nature, art, history or religion. In all these contexts, intensive experiences are possible that make life experienceable as an intensive encounter or relationship for its own sake. This is juxtaposed with silent or instrumental world relations, determined by the orientation towards domination and making available, which are primarily concerned with the achievement of a useful goal. For example, a mountain tour can be a resonance experience as an intensive confrontation with the demands of the path and the encountering nature, as a purely purpose-oriented company but also instrumental and in this sense "mute". Obviously, world sections that are perceived as attractive or desirable are predestined for resonance experiences, while those that are perceived as hostile or anxious are expected to be "silent", non-resonant experiences. Another prerequisite for the establishment of resonances are strong evaluations of the subject, which give the object a significance that goes beyond desire or attractiveness. If an attempt is made to outline as resonance what people seek and long for in their
