In political philosophy, the concept of rights is vigorously debated. Most political theorists accept the concept of human rights, but differ in their understanding of what is to be considered a legitimate right. A classical liberal approach is to understand rights as basic individual guarantees against arbitrary actions from a political majority. But how are we to decide what justifies a moral right? Should basic welfare, so-called positive or social rights, be considered a right in the same way as freedom of speech? And is there any conflict in the different visions of moral rights? How can we resolve the many contemporary disputes about rights within the field of political theory?
