There is no difference.
The philosophers that developed the theory of natural rights did so as a contrast to the so-called "divine rights".
The central concept of the so-called natural rights is that said rights are "not contingent upon the laws, customs, or beliefs of any particular culture or government, and therefore universal and inalienable."
Wiki As we've established time and again,
ALL such rights enumerated by the philosophers
ARE contingent on laws, customs and beliefs of a society. If they were not, then we would ALL have a consistent understanding of what these so-called natural rights are, etc. Since society's views of what is a right, the limits of said rights are, who can exercise said rights, in case of conflicts between parties whose rights shall be preferred, etc change and evolve over time and are still subject to debate what you are referring to as natural rights - universal and inalienable - cannot exist.
