A natural right in the strict sense is that which is naturally under a person’s control, his body with its faculties of movement, feeling, thought, and speech. By extension, a natural right is what a person brings under his control without violating any other person’s natural rights.

As a slave one cannot undertake obligations without the consent of one’s master. As a citizen one cannot undertake obligations unless the legal system of the State in which one holds citizenship permits one to do so. Neither a slave nor a citizen is a free person, although those who are held as slaves or citizens may well be free persons: it is just that their freedom is not respected.Frank Van Dun
I recall an incident involving the late George Stigler at a conference in Spain in the 1980s. Hearing that I had written a book on reason and natural law, Stigler started to ridicule reason, going so far as to say that there is as much reason in a monkey's antics as in any human act. At that point I asked him whether he was trying to tell me something about how he wrote his books; he gave me a blank stare and stormed out of the room.Frank Van Dun
