Jurisprudence is the philosophy and theory of law. It is concerned primarily with both what law is and what it ought to be. That includes questions of how persons and social relations are understood in legal terms, and of the values in and of law. Work that is counted as jurisprudence is mostly philosophical, but it includes work that also belongs to other disciplines, such as sociology, history, politics and economics.
Philosophy of law is a branch of philosophy that examines the nature of law and law's relationship to other systems of norms, especially ethics and political philosophy. It asks questions like "What is law?", "What are the criteria for legal validity?", and "What is the relationship between law and morality?" Philosophy of law and jurisprudence are often used interchangeably, though jurisprudence sometimes encompasses forms of reasoning that fit into economics or sociology.
