No. Natural Law(behavioral) is the equivalent of saying Laws of Nature (physical). As with physics, if we begin with the greeks (Aristotle, Epicurus, Democritus) it took a long time to develop the physical sciences. And likewise, it took a long time to develop the behavioral sciences. However, it’s just as possible to reduce them to first principles (irreducible laws) as it has been physics. It took us longer frankly (a) because it’s more complicated and (b) we don’t want to believe it, even more than we don’t want to believe evolutionary laws (darwin).
But, here we are. Physical Law, Behavioral Law, Evolutionary Law.
