Science or philosophy of law. Jurisprudence may be divided into three branches: analytical, sociological, and theoretical. The analytical branch articulates axioms, defines terms, and prescribes the methods that best enable one to view the legal order as an internally consistent, logical system. The sociological branch examines the actual effects of the law within society and the influence of social phenomena on the substantive and procedural aspects of law. The theoretical branch evaluates and criticizes law in terms of the ideals or goals postulated for it.
