A kind revealed by ordinary people. For them, historical laws are also objective reality, which refers to historical phenomena that have appeared many times in the course of historical development and have similar appearances or essential commonalities, as well as their internal and external essential relations. Revealing historical laws is the expression that people explore its deep causal relationship through historical appearances and reveal the universality, unity and inevitability of historical development; It is people's dissatisfaction with the superficial description of history, hoping that history can learn from reality and predict its future performance. Because the revelation of historical laws is an abstract understanding of the deep structure of history and is imperceptible, it is possible to cast more subjective influence. Therefore, we can also say that the historical law is a subjective abstraction and induction of the above historical phenomena and connections. In other words, some things that were once considered as historical laws were later proved to be irregular by history; Other things that were once considered as accidental phenomena were later proved to be laws by history, so historical laws are the products of historical laws and are often restricted by various subjective and objective conditions. In this way, on the one hand, the historical law is an objective law that did exist in human society, on the other hand, it is subjective, because it can not be obtained by experience and can not be proved by experiments immediately, so it is a special thing. It has similarities and differences with natural law. This shows that historical science is a special science.
