To summarize, this book is about the idea that what’s at the core of a good life, a flourishing human existence, is something that Rosa calls “resonance.” “Resonance” is just some kind of vibration or harmonization between the individual and the rest of the world. You could use lots of other metaphors, but it’s basically about being “in tune” in a certain way. And, crucially, it’s a kind of relationship to the world that involves quite a lot less control over events than we tend to think that we want, or than states and governments and bureaucracies and social institutions often to try to achieve.
