Natural Law

Margaret MacDonald brings to light some pretty interesting questions, such as, how can facts about nature be discovered which have never been observed or confirmed by observation? She is talking about natural laws and how they are imperfect according to mans law. How natural laws are unwritten, might even be unknown, yet applies to all men everywhere. And how natural laws are only imperfectly realized through positive laws, is that to say that there could be some natural laws out there that we have not reasoned with yet. For instance the proliferation of laws/rights in recent times have brought forth laws which never were considered rights before they were brought up, now that they are in open view being debated people are thinking that they are “natural” human rights. Why all of a sudden have we expanded and fought for rights in away never before seen? MacDonald says that we are able to know these natural laws through reason because men can reason; so the greater our intellectual capacity becomes, the better our reasoning becomes and thus the more natural laws are realized through this? I might be way off, but if natural laws are only imperfectly realized through positive laws, then the proliferation of rights in recent years might not be as bad as we think if in fact we are realizing new natural laws through this.
