innermost being, it is by no means conceived as a permanent state that can be established, but always as a selective, momentary success or self-adjustment that stands out against the background of the predominantly silent, instrumental. Resonance in this sense is therefore essentially characterized by the fact that it cannot be produced systematically and intentionally, but is ultimately unavailable. Social theory As a sociological theory, resonance theory deals with the social conditions that promote or hinder successful relationships. If the striving for resonance is regarded as ubiquitous human primary motivation, its concretization depends to a large extent on historical, geographical and cultural conditions. In particular, existential hardship and political repression complicate resonance experiences if they do not make them completely impossible. The promise of modernity is therefore to make resonance possible by overcoming political arbitrariness and improving material resources. Rosa sees this promise as an inherent contradiction of modernity, however, undermined by the conditions that progress, which is primarily geared to increasing resources, ultimately requires: Expanded resources expand the world accessible to the subject and thus his possibilities for resonance experiences. This results in a logic of increase, which requires a constant continuation of improvement and multiplication of resources. This is accompanied by an increasing pressure to accelerate: in order to maintain the status quo within a modern society, an increasingly rapid increase in services, innovations and material production is necessary. Rosa sees this mode of dynamic stabilization as constitutive for modernity: while pre-modern societies transform themselves adaptively, i.e. in response to changed conditions, modern society is virtually defined by its compulsion for continuous transformation. While the current phase of late modernism is characterized by a high resonance sensitivity and expectation of its subjects, the mode of dynamic stabilization results in a loss of resonance possibilities. Rosa notes three essential manifestations of the current crisis of modernity: the ecological crisis due to the finite nature of natural resources compared to an unlimited expectation of increase the political crisis, which arises essentially from the fact that democratic negotiation processes are too slow for the accelerated technological and resulting social changes and are therefore regarded as ineffective or obsolete, and the psychological crisis of the subjects, which is overwhelmed by the acceleration and therefore see itself exhausted (burn-out). Resonance theory is thus in the tradition of critical theory from Marx to Adorno and Horkheimer to Habermas and Honneth. It shares the central
