Jurisprudence

Positivists and naturalists tend to converge in the area of historical jurisprudence. Historical jurisprudence is marked by judges who consider history, tradition, and custom when deciding a legal dispute. Strictly speaking, history does not completely fall within the definition of either positivism or natural law. Historical events, like the Civil War, are not legislative enactments, although they may be the product of governmental policy. Nor do historical events embody eternal principles of morality, although they may be the product of clashing moral views. Yet, historical events shape both morality and law. Thus, many positivists and naturalists find a place for historical jurisprudence in their legal philosophy.

For example, Justice Holmes was considered a positivist to the extent that he believed that courts should defer to legislative judgment unless a particular statute clearly violates an express provision of the Constitution. But he qualified this stance when a given statute "infringe[s] on fundamental principles as they have been understood by the traditions of our people and our law" (LOCHNER V. NEW YORK, 198 U.S. 45, 25 S. Ct. 539, 49 L. Ed. 937 [1905]). In such instances, Holmes felt, courts were justified in striking down a particular written law.

BENJAMIN N. CARDOZO, considered an adherent of sociological jurisprudence by some and a realist by others, was another Supreme Court justice who incorporated history into his legal philosophy. When evaluating the merits of a claim brought under the DUE PROCESS Clauses of the Fifth and Fourteenth Amendments, Cardozo denied relief to claims that were not "implicit in the concept of ordered liberty" and the "principle[s] of justice [that are] so rooted in the traditions and conscience of our people as to be ranked as fundamental" (Palko v. Connecticut, 302 U.S. 319, 58 S. Ct. 149, 82 L. Ed. 288 [1937]).
