'It makes nonsense to say that men have, on the one hand, rights, and on the other hand, obligations. Such words only express differences in point of view. The actual relationship between the two is between object and subject. A man, considered in isolation, only has duties, amongst which are certain duties towards himself. Other men, seen from his point of view, only have rights. He, in his turn, has rights, when seen from the point of view of other men, who recognize that they have obligations toward him. A man left alone in the universe would have no rights whatever, but he would have obligations.'
Simone Weil, The Need for Roots: Prelude to a Declaration of Duties Towards Mankind, p.3.
