The article considers the historical transformations of the law, and argues that many contemporary scientists are wrong to ignore it. The paper criticizes the approach to the status of laws, which is determined by the degree of their compliance with the criteria of objectivity and rationality. Instead, a classification is constructed that includes the laws of logic and mathematics, natural sciences, technology, as well as social and legal. To consider the processes of unfolding laws in the evolution of reality, the concept of nomogenesis is used. The unification of laws is achieved due to the fact that they are all determined by the balance of their characteristic tendencies: objective / subjective, rational / extra-rational, determination / will. Special attention is paid to social and legal laws. The case of defining three social laws is offered.
