The differences between the two is that Natural Law theory focuses on the legitimacy of law from a morality and justice based standpoint while Legal Positivism draws from the authority of the lawmaker and the process of lawmaking.

Legal positivism provides a clear framework for understanding the law based on rules and principles established by authority. It helps maintain stability and predictability in legal systems by emphasizing the importance of written laws rather than moral or ethical considerations. Additionally, it can help prevent arbitrary decision-making by requiring adherence to established legal processes.

The three major theories of law are natural law theory, legal positivism, and legal realism. Natural law theory posits that law is derived from universal moral principles. Legal positivism suggests that law is based on society's rules and conventions. Legal realism emphasizes the role of judges in shaping the law based on practical considerations.
