Dworkin’s and other analytic/positivist philosophers’ theoretical approach to law leads inexorably to politicization, totalitarianism, less justice, less trust in government, and less truth. A more practical approach is Fuller’s, which is based on experience of human behavior and an analysis of what has worked in the past. That is also the approach traditionally used in the common law system. This article uses a comparative study of the two Western traditions, their history, and their most prominent legal philosophers to explicate how and why Dworkin’s and Fuller’s approaches are consistent and inconsistent with those traditions, followed by a comparative analysis of the results obtained by prominent international NGOs. Dworkin’s approach, which grows out of analytic philosophy, is unworkable because like all scientistic theories, it treats human beings mechanistically, de-emphasizing personal responsibility, ignoring the need for individual incentive, and it assumes an all-encompassing, all-powerful government of experts to make legal decisions for a collectivity. Under Fuller’s common law approach, the proper role of law is to manage conflict, as it cannot be prevented and cannot always be resolved, thus building the public’s trust in government as unbiased and apolitical as possible. This concept of the rule of law places law above government, minimizes politicization, incentivizes personal responsibility, individual incentive, and entrepreneurship, and is the only true common good among men.
