Jurisprudence is the science or philosophy of law. According to Farlex (2009) Criminal Jurisprudence can also be thought of as; "law as a science or philosophy or a system of laws or a particular branch of law or the branch of philosophy concerned with the law and the principles that lead courts to make the decisions they do." The Merriam-Webster Online Dictionary states that, "Jurisprudence means, Symptoms, Causes, Treatments of Jurisprudence 1: the science or philosophy of law 2 a: a system or body of law b: the course of court decisions 3: a department of law ." It is always a good idea to have these distinctions when it comes to law. It is far easier to classify things if there is already a classification for them. Lawyers, courts and the government can properly handle anything that comes their way because they have a system in place to handle these things. If one wants to study the science or philosophy of law they can start by learning the different classifications like Criminal Jurisprudence for example.
Now that we know what Criminal Jurisprudence means we can further examine its uses. Cornell University Law School states, "The word jurisprudence derives from the Latin term juris prudentia, which means "the study, knowledge, or science of law." In the United States jurisprudence commonly means the philosophy of law. Legal philosophy has many aspects, but four of them are the most common. The first and the most prevalent form of jurisprudence seeks to analyze, explain, classify, and criticize entire bodies of law. Law school textbooks and legal encyclopedias represent this type of scholarship. The second type of jurisprudence compares and contrasts law with other fields of knowledge such as literature, economics, religion, and the social sciences. The third type of jurisprudence seeks to reveal the historical, moral, and cultural basis of a particular legal concept. The fourth body of jurisprudence focuses on finding the answer to such abstract questions as What is law? How do judges (properly) decide cases?"
It also states, "Apart from different types of jurisprudence, different schools of jurisprudence exist. Formalism, or conceptualism, treats law like math or science. Formalists believe that a judge identifies the relevant legal principles, applies them to the facts of a case, and logically deduces a rule that will govern the outcome of the dispute. In contrast, proponents of legal realism believe that most cases before courts present hard questions that judges must resolve by balancing the interests of the parties and ultimately drawing an arbitrary line on one side of the dispute. This line, realists maintain, is drawn according to the political, economic, and psychological inclinations of the judge. Some legal realists even believe that a judge is able to shape the outcome of the case based on personal biases."
P.S. I would put more into your own words. I don't think you can quote that much. Hope it helps.
