For dblack's sake, I have got to respond to this, though I have no more to say to those whose minds are closed to the ramifications of human consciousness, either as a matter of sociopathy, pride or trolling, and that is not a personal attack as such, merely a statement of fact.
dblack, there is absolutely nothing spiritual about the facts of natural law. Clear the cobwebs of post-modern sloganeering from your mind; they're obscuring the reality of things for you. The imperatives of the Golden Rule just are . . . in nature!
Are you saying you don't understand that murdering or oppressing or robbing another is wrong? More to the point, are you saying you would have another murder or oppress or rob you?
Start there, and stay there as long as it takes to sink in. Forget the rest for now.
What is esoteric or mystical about that?
What's hurting your head are the esoteric and mystical roadblocks of relativism's inscrutable mumbo jumbo: they are standing between you and the apprehension of the reality in which you live.
Why would any sensible person give a hoot about an inscrutable distinction that would make no difference to us in everyday reality? There exists for us no means by which to quantify it, let alone qualify it. Use your wits and bear down on reality as it is for us. There's already more than enough complexity in that, enough to boggle the mind for eternity. Why do you make things harder than they are?
Natural law = natural morality. Natural morality = natural law. Same thing. Natural, not supernatural.
Foxfyre is wrong to say that natural rights have nothing to do with morals; they have everything to do with morals as bottomed on the of reality of human (sentient) nature. What's the first principle of morality with regard to natural rights? Knowing where your rights end, for that is the point at which another's begin.
The moral distinction between a genuine right and an ability is the same moral distinction between natural rights and government tyranny stomping all over the former under the guise of civil protections. But to be fair to her, I'm pretty sure she was speaking in a different context as she just made the same point to another, effectively, regarding this very moral distinction.
Also, natural law is not religious in any supernatural or theistic sense at all as bottomed on nature.
However, it is not unreasonable to say that natural law is natural religion, but not in the sense that's clouding your thinking at all.
Besides, my occasional allusions to nature being ultimately grounded in an eternally subsistent and, therefore, transcendent reality beyond the same is not religious as such, but ontological. If those allusions are causing you to confuse the facts of nature in this regard, disregard them for now. They're not immediately relevant, just instructive.
But like I said, just concentrate on the following for now:
You know that murdering or oppressing or robbing another is wrong, because you know that you would not have another murder or oppress or rob you.
Natural law = natural morality. Natural morality = natural law. Same thing. Natural, not supernatural.
Grasp that and you're on your way.
