“Modern masters of science are much impressed with the need of beginning all inquiry with a fact,” said G. K. Chesterton. “The ancient masters of religion were quite equally impressed with that necessity. They began with the fact of sin—a fact as practical as potatoes.”
Recognizing the fact of sin should be the beginning of all inquiries in how we should arrange public policy. This is especially true for those of us who champion liberty. Because order is a necessary precondition of liberty, we need to maintain order by limiting and impeding certain types of sinful behavior.
Throughout human history, sin has been restrained through norm, rules, customs, and laws, and traditions. Inevitably, certain individuals push back against these restrictions and complain that they hinder their own personal liberty. Sometimes this is true, of course, but more often than not it is merely an individual wanting to put their own self-centered actions and behaviors ahead of the reasonable needs of society.
Some have argued that as long as only a relatively few people break the norms and rules that it would have little to no affect on society. But this misses, as Chesterton might say, the fact of sin, especially the fact of sin as a social contagion.
Take, for example, the victimless crimes of prostitution, vagrancy, or public drunkenness. Theoretically, we could justify the decriminalization of all these acts since they do not necessarily harm other people or their property. I’m not likely to become a vagrant because I see one on the streets, so what harm does it do?
