In this important new book, Norberto Bobbio provides a valuable clarification and defence of human rights. He argues that the development of human rights is an historical sign of progress in a world marked by the proliferation of cruel wars, the arms trade, pollution, famine and almost universal pessimism. Drawing widely on the work of Kant, Locke, Beccaria and Paine, Bobbio argues that the French Revolution is a crucial event in moulding our ideas and attitudes today. He suggests that the proclamation of rights does not necessarily mean that those rights are actually enforced. He carefully traces the development of human rights through various 'generations' - libertarian, social, ecological - and argues that the recognition and effective protection of human rights are the foundations of modern democratic institutions. Human rights, democracy and peace are the three essential components of the same historic movement.
