What is Natural Law?

As we have stated elsewhere, natural law, as that part of the eternal law which applies specifically to human beings, is the rule or norm of practical reason which governs all human actions. Natural law is “natural” because it is based upon human “nature”—what humans “are” as designed by their Creator—and not upon the human will. Natural law is a “law” because it is not only binding (prescriptive and proscriptive commands) on all humans, but also because it directs all humans to their proper end and common good, and is in principle knowable by all humans. Some might wonder about the promulgation of natural law, suggesting either (1) that it is not promulgated, as there is no “place” where one can find it written down, or (2) that it is not promulgated, because it appears that not all are aware of it.

To the first objection, we reply (a) that it is inscribed on the mind of man—it is more naturally anchored in the mind of man than the Operating System and basic applications are in a newly purchased i-Phone.⁹ Furthermore, (b) as if “permanent inscription” of the law on the mind of man was not sufficient, many of the early Reformers held that God also “published” the main tenets of natural law in the 10 Commandments given to Moses on Mount Sinai.

To the second objection, we reply that ignorance of a law is proof neither that the law was not promulgated, nor that one can be held non-guilty if one breaks the law. It is simply not the case, even in our technologically advanced age, that all of those who live within any given municipality are aware when new laws are created, even though they may be posted publicly. Even if one is not aware of a law which has been promulgated, one is still held responsible for knowing about it (and seeking to find out what regulations may apply to any socially affective action one makes), and one is considered guilty for breaking the law whether one knows about it or not. In the same way, though the Natural Law is equally promulgated to all, it is not necessarily equally known by all. Just as there may be many who are unaware of the laws in a given area, there may be many who, due to lack of time, training, or ability, or due to negligence (vicious or innocent), have less knowledge of the givings of the Natural Law than others. However, the Natural Law is sufficiently promulgated that those who break it are rightly condemned.
