History is not a law? This is significant problems in the theory of historical philosophy, Popper is a critique rationalism of Western representative. He criticized historicism and historical law systemly.

The first part, from the perspective of contemporary Western philosophy, history, analyses the situation of the law, including the major schools of contemporary Western philosophy, humanistic philosophy, philosophy of positivism and post-modernist view of the law of history of philosophy. The second part describes Popper's doube of the law of history, that is history's mysteries can not be cognitive which means that history is meaningless, there isn't a law of historical development but a trend. Historical prophecy is built on the basis of the history of law. If there is no laws of history, the history of prophecy is impossible. The third part reveals and discusses the historical development of the law, the law of manifestation, the relationship between the law of history and human activities in line with the relationship of the historical process of purpose and regularity.This part is to verify the existence of objective laws of history.It is great value of Popper's denial of the discourse on the laws of history. It is helpful for people to study Marx's concept of law from a deeper, broader historical perspective.
