The article discusses how different legal theories view the relationship between law and morality. Some believe they are separate, while others see them as connected. The authors explore how legal positivism and natural law can be integrated, leading to a new perspective called 'non-positivism'. This challenges traditional ideas about law and opens up new ways of thinking about legal theory. The debate between Joseph Raz and Robert Alexy highlights the ongoing discussion about the role of natural law in legal theory. The study suggests that Kelsenian legal positivism still has relevance in understanding the nature of law today.
