The discussion of the possibility of world government has been revived since the end of the Cold War and particularly after the turn of the millennium. It has engaged many authors. In this article, I provide a survey of the continuing debate on world government. I explore the leading question of the debate, whether the conditions of insecurity in which states are placed and other global problems that face contemporary humanity require the creation of a global authority, and consequently, the (...) establishment of a world state. After a careful analysis I suggest that a world state is neither necessary nor inevitable nor desirable. I argue that the plurality of nation-states that form an international society has a great advantage over a world state. It supports the diversity of character and culture, and sustains the continuous progress of humankind. (shrink)
