Can you sum up your viewpoint on just what natural law is?
Natural Law is that law within us where, if we were to observe one man doing away with another man because of something the second man had done, we would either help or at least not hinder the first man in carrying out his doing away of the second man because it is in accord with our inner notions of justice and right.
I.e., a man one catches man two attempting to murder a member of man one's family, or steal something from man one, or undermine the society man one belongs to, or commit adultery with man one's wife, or rape man one's daughter, or kidnap man one's son, etc. And man one, having caught man two, is observed by man three who either applauds or helps man one do away with man two.
Natural Law is the mode of justice which naturally occurs among men in the absence of State authority - i.e. in a frontier or wilderness, during natural disasters, etc., or which even springs up spontaneously in a civilized judicial culture in the absence of an immediate police presence during the commission of a crime (i.e. the rough justice given out to a mugger caught by the citizenry, or an intruder shot in a house).
Natural Law is the natural condemnation of murder, theft, adultery, lying, blasphemy, sacrilege, treason, rape, kidnapping, etc. because these things are wrong and harmful in and of themselves, and we know it without God revealing it to us by light of our own reason about how society is best ordered for the preservation of everyone's enjoyment of their life, liberty, and property.
