Currently, two research approaches in the academic community have not yet been clearly revealed, which are the history of thought on “the Second Integration” and the intellectual history related to “the Second Integration”. The former approach is based on the current situation and is an analysis of the reasoning and deduction based on the order of categories of “the Second Integration”. The latter approach is based on intellectual history and tends to explore the historical theories and practices related to “the Second Integration”. After careful evaluations of both, the research approach of the intellectual history of “the Second Integration” has more significant academic rationality and stronger research potential. The advantages of this approach are not only reflected in the differences in the history of thought on “the Second Integration”, but also in the traditional Chinese context and periodization context in terms of academic significance. It shows the degree of Sinicization in dealing with issues in the history of thought through dialogue, refutation, and integration among different ideological systems, as well as the reconstruction of the history of thought for solving contemporary problems. Therefore, it can not only fully explore the theoretical advantages of “the Second Integration” in terms of thinking mode, ideological resources, and theoretical height, but also realize the interpretation of the history of thought in a way that transcends the history of thought by completing the intellectual reconstructions, providing intellectual resources that are both effective and legitimate for contemporary issues.
