Exploring the deep philosophical principles of the “historical initiative spirit” has driven further discussion of major issues in the study of laws. The first question is whether historical laws follow natural laws. It is related to the method of exploring social laws. The perspective of the possibility of long-term neglected natural laws can be used to explain the conditionality and subjectivity of historical laws, as well as to grasp the unity of the objectivity of social laws and the selectivity of specific paths. The second question, related to the relationship between laws and basic elements of things, is what the determining factors of the laws are. The answer to this question helps to clarify the conditions for the breeding, emergence, and development of social laws. The third question is whether the subject can create laws. It involves the possibility and selectivity of science, the “for me relationship” and “from other relationships” of historical activities, the “intrinsic value” and “external value” of historical activities, and the general and special laws of historical activities. The fourth question is how the subject understands and masters the laws. Attention should be paid to paths to mastering laws, such as from unrepeatable historical events to repeatable laws, from psychological motivation to “underlying determinants”, and from individual power to “social synergy”.
