ABSTRACT
The relationship between the purposiveness of human activities and the regularity of social development is an important part of historical materialism. However, many ambiguities or even mistakes may challenge the understanding of this issue. As a result, it is necessary to clear these ambiguities and mistakes through accurate interpretation. Human activities are purposeful, whereas social development has its objective laws independent of human purpose. This may be a synopsis of the relationship between the purpose of human activities and the regularity of social development. The “development of social forms” is equivalent in meaning to “social development.” Semantically, the proposition of “the unity between the regularity and the purposiveness of social development” argues that the regularity of social development is consistent with the purpose of human activities. This is necessarily so because social development has its objective laws independent of human will and purpose.
