英文摘要：

Marx＇ historical materialism with its philosophical statement that ＂the problem is changing the world＂ realized the histori- cal turn of philosophical topics, a conversion to convert social production logic, capital logic, scientific logic, free logic as its ontologi- cal basis. The underlying interpretation framework for social project thinking is the unity between social decisiveness and selectivity of unity, the unity between reality and social necessity, unity between theoretical rationality and practical rationality. But social engi- neering philosophy constitutes three basic dimensions of ＂perceptual pe~;son activity＂, organic unity oE social life and production, life, and the modernization of society, man and scientific teehnology.
