The book explored the following topics:
· The tragedy of the commons is presented as the best explanation of why we do so little to obviate the causes behind climate change.
· A world government presents a way out of the tragedy of the commons.
· Standard arguments against a world state are examined.· The question of whether it matters if humanity goes extinct is taken seriously.
· What if the attempt to establish a world state fails.
The book is written by a philosopher, but the intended audience is broad. It has a place in courses in political philosophy, but it is possible for anyone who wants to do so to dig deeper into the questions should be able to read it. And regardless of whether you who read the book are a scholar or a layperson, there is no way for you to avoid its topic. Global existential issues concern all of us, regardless of profession or nationality.
