Hartmut Rosa (born August 15, 1965) is a German sociologist and political scientist, most well known for his theory of resonance and temporal sociology of social acceleration.

In 1997, he graduated summa cum laude from the Humboldt University of Berlin and received his Ph.D. for his dissertation on political philosophy according to Charles Taylor.

He received the Feodor Lynen Research Fellowship of the Alexander von Humboldt Foundation for his work as a visiting professor at the New School University in New York City in 2001–2002.

[6] Rosa's sociological work on time appears most prominently in his habilitation thesis “Social Acceleration: The Change in Temporal Structures”.

Most recently, he has dealt in particular with the topos of desynchronisation, i.e. the increasing divergence of the time structures of various social sub-areas such as politics and the economy.

[9] In response to the "communitarianism debate": Rosa particularly advocates the "dignity of labour" and its social orientation and benefits for the common good, especially in reference to the topic of socio-ecological degrowth.

[10] He has further written several (introductory) texts on communitarian political and democratic theory, including his dissertation on the Canadian philosopher Charles Taylor.

This intends examining the contexts of tradition and discourse as well as normative or ideological implications, in which he sees the central concern of a critical conceptual history.

[14][15] Felski argues that the idea of resonance “pushes back against regimes of accounting in the contemporary university: the ubiquitous rhetoric of metrics, impact factors, and citation indexes”, all areas which overlook the act of learning as something with is self-transformative and brings together “cognition and emotional, analysis and affect” whose “outcomes cannot be known in advance.”[14] Psychologist Svend Brinkmann has stated that Rosa's sociology of world relations invites us not to “reduce our relationship to the world to one of active agents that use passive resources as this easily mirrors the experiences of alienation in modernity.”[16] Brinkmann proposes that cultural psychology should do more to take patients’ accounts of world relations and resonance more seriously.
