Positivists argue that there is no connection between law and morality and the the only sources of law are rules that have been expressly enacted by a governmental entity or court of law. Naturalists, or proponents of natural law, insist that the rules enacted by government are not the only sources of law. They argue that moral philosophy, religion, human reason and individual conscience are also integrate parts of the law. There are no bright lines between different schools of jurisprudence. The legal philosophy of a particular legal scholar may consist of a combination of strains from many schools of legal thought.
Some scholars think that it is more appropriate to think about jurisprudence as a continuum.
The above mentioned schools of legal thoughts are only part of a diverse jurisprudential picture of the United States. Other prominent schools of legal thought exist. Critical legal studies , feminist jurisprudence , law and economics, utilitarianism, and legal pragmatism are but a few of them.
