Jurisprudence is the study and theory of law.
Bentham was the first one to analyse what is law. He divided his study into two parts:
1. Examination of Law as it is- Expositorial Approach- Command of Sovereign.
2. Examination of Law as it ought to be- Censorial Approach- Morality of Law.
Two main streams are:
1. Natural Law: or the law of nature. Human laws that come from enternal (never ending) and unchangable. It is a system of law that is determined by nature, and so is universal. Classically, natural law refers to the use of reason to analyze human nature — both social and personal — and deduce binding rules of moral behavior from it. natural law can be invoked to criticize judicial decisions about what the law says but not to criticize the best interpretation of the law itself.
2. Positive law: are human-made laws that oblige or specify an action. It also describes the establishment of specific rights for an individual or group. positive law may be characterized as "law actually and specifically enacted or adopted by proper authority for the government of an organized jural society.

i. Unauthoritative Writings
