First Published in 2016. In this book starts with the discussion located at the crossroads between two basic political principles. The first one is the democratic idea of representative government, based on elections by general suffrage. The second is the nation-state principle which says that the world is divided into sovereign states and that only those who are citizens can claim a right to take part in political life, in other words that foreign citizens are not allowed to participate in political elections. Democracy is honoured almost everywhere, at least as a principle, but the modern system of states presupposes that as a general rule only those who are citizens are entitled to vote, to stand for election, to join parties, and to participate in political debate and give voice to their political demands and interests. Both these basic political principles are young, and their pre sent confrontation is therefore also new to us.
