Modern science has developed the notion of "natural laws" to describe the apparent sequential patterns of the most complex parts of the physical world. But it cannot tell us what we ought to do about arms production, or human sexuality or abortion or race, or death. Non-teleological science can no more tell us that nuclear fusion is immoral than it can tell us what is the natural purpose of the solar system. Natural Law, however, can tell us what ought to be done in light of the nature of law. If indeed the nature of law is that it is directed toward the accomplishment (actualization) of the proper (just) ordering (a rational and effective structure) of relations (social interactions) among men (human persons in their various states of being), then we can make justifiable evaluative judgments. We can logically call laws good or bad, just or unjust, wise or stupid. What natural laws cannot do, natural law is equipped to do.
