The basic idea at the heart of human rights is that all human beings are equal: equal in rights – equal in human dignity. This idea is universally accepted and believed. At the same time another idea – the idea that we are separately citizens of different countries is also a feature of the modern world – and the way it is practised has led to enormous discrimination and violation of human rights. In reality people, as a matter of law, have different fundamental rights even though we believe that all human beings are equal.
