First,"Dreams of the Red Chamber" is a complete overthrow of the Chinese traditional twenty-four histories, and has opened up for us, in a gigantically breading way, the third pedigree of human history with the male and female love as the core and different from the pedigree with the dual division between the good and the bad. Next, along with the affirmation of the third pedigree of human beings,"Dreams of the Red Chamber" enable the female sex acting as the "second sex" for long to come again onto the stage in the human history, thus unprecedentedly disclosing the incomparably grave historic tragedy of the female sex in reality. Finally, more importantly,"Dreams of the Red Chamber" not only consider the ruling of the current discourse as the deepest cause of the female tragedy but also make a restoration with the meaning of the life generation science for the human discourse so as to make the initial word "discourse of love" more original than the discourse of the knowledge nature and bring the following of "God of lover", the new salvation way, into the agenda.

首先，《红楼梦》是对中国传统二十四史的彻底颠覆，并大破大立地为我们开辟出有别于善恶二分谱系的一种以男女情爱为核心的人类历史第三谱系；其次，随着对这一人类第三谱系肯定，《红楼梦》使长期作为&第二性&的女性在人类历史中重新登场，并前所未有地揭露了现实中女性无比深重的历史悲剧；最终，更重要的是，《红楼梦》不仅把现行话语的统治视为女性悲剧的最为深刻原因，而且同时对人类话语进行了一种生命发生学意义的还原，而使一种有别于知识性话语的更为始源的&情的话语&这一泰初之言得以彰显，把对&情的上帝&的昄依这一新的救赎之途提到人类文化的议事日程。
