His contributions to historical philosophy include the following: his study of the origin of time as the historical process itself is a combination of the priori and the postpriori in history that can testify the relationship between, historical philosophy and historiography; he establishes the criterion for evaluating the times by dividing time into time in conception and chronological time; he testifies the unification of cosmopolitism and patriotism based on a discussion of the relationship between the general and the individual; he describes human history as a long and arduous process in which rationality wins over irrationality and civilization wins over barbarism, a dialectical revelation of historical process.
