There are many examples of the libertarian approach in the American legal system, including aspects of contract and tort law. The real implication of libertarianism is that the winners in society must compensate the losers in order that no one is worse off. As described above, jurisprudential theory is based on a pragmatic blending of egalitarian, libertarian, and utilitarian ethics. The law stands guard over individual human rights. Engineers who enjoy individual freedoms may cherish them as citizens, but nevertheless fail to include their costs in the professional analysis of an engineering product or service.
Individual liberties are expensive.
While democratic principles permit a majority to select lawmakers, the law requires that individuals be treated fairly by society. The tension within the law itself among egalitarianism, libertarianism, and utilitarianism requires that each point of view be expressed. Engineers enrich the way the law works by advocating the utilitarian position. However, the goal of the law is the avoidance of disputes, or, failing that, the resolution of disputes in a manner acceptable to society. Engineers should understand the utility of diversity in the complex process for reaching this goal.
