Legal Positivism is a theory of law that emphasizes the importance of written laws and regulations created by human authorities. According to this view, laws are valid not because they are morally right, but because they are enacted by legitimate institutions, such as legislatures or courts. Legal Positivists argue that the existence of law is separate from moral considerations. This approach contrasts with other legal theories, such as Natural Law, which asserts that laws should reflect moral principles. Prominent figures in Legal Positivism include H.L.A. Hart and Jeremy Bentham, who focused on the systematic analysis of legal systems and the role of social facts in determining the validity of laws.
