Full Idea
The idea of a cosmopolitan right is not fantastic and overstrained; it is a necessary complement to the unwritten code of political and international right, transforming it into a universal right of humanity.

There are political and inter-national rights, but also universal cosmopolitan rights

A Reaction
The interesting thought is that there are no 'natural rights', but there can be universal rights insofar as there exists a universal community. See the UN Declaration of Human Rights c.1948.
