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.

Normative generally means relating to an evaluative standard. Normativity is the phenomenon in human societies of designating some actions or outcomes as good, desirable, or permissible, and others as bad, undesirable, or impermissible. A norm in this sense means a standard for evaluating or making judgments about behavior or outcomes. "Normative" is sometimes also used, somewhat confusingly, to mean relating to a descriptive standard: doing what is normally done or what most others are expected to do in practice. In this sense a norm is not evaluative, a basis for judging behavior or outcomes; it is simply a fact or observation about behavior or outcomes, without judgment. Many researchers in science, law, and philosophy try to restrict the use of the term "normative" to the evaluative sense and refer to the description of behavior and outcomes as positive, descriptive, predictive, or empirical.
In ethics, value pluralism is the idea that there are several values which may be equally correct and fundamental, and yet in conflict with each other. In addition, value-pluralism postulates that in many cases, such incompatible values may be incommensurable, in the sense that there is no objective ordering of them in terms of importance. Value pluralism is opposed to value monism, which states that all other forms of value can be commensured with or reduced to a single form.

Pragmatic ethics is a theory of normative philosophical ethics and meta-ethics. Ethical pragmatists such as John Dewey believe that some societies have progressed morally in much the way they have attained progress in science. Scientists can pursue inquiry into the truth of a hypothesis and accept the hypothesis, in the sense that they act as though the hypothesis were true; nonetheless, they think that future generations can advance science, and thus future generations can refine or replace their accepted hypotheses. Similarly, ethical pragmatists think that norms, principles, and moral criteria are likely to be improved as a result of inquiry.
Ethics is, in general terms, the study of right and wrong. It can look descriptively at moral behaviour and judgements; it can give practical advice, or it can analyse and theorise about the nature of morality and ethics.
