What does prosperity actually mean today? How can we live in a way that ensures well-being for all people while operating within ecological limits? The solution may lie in a different appreciation of time. The authors therefore pose the question of what a good life really is and examine the role of time, work, and a healthy environment for our well-being. Clearly understandable yet academically grounded, the book offers an engaging introduction to the debate on sustainable economics and develops visions for a justly designed future. And if you happen to have two superconducting pipes and some helium on hand, you can even build a time machine with the included instructions.
