As I wrote earlier, the concept of rights arose from the study of the nature of man.
Sure would love to read the research report on this "study". Got a link?
Yes, and would this study be a scientific treatise... or a philosophical reflection? Is there a single authoritative study, or is is a matter of opinion and discussion? Is the study a reflection of the culture from which it emerged so that other cultures would inherently agree as might be the case of a study of particle physics or chemistry?
