摘要：

《三体》是一个改变世界框架的思想和文学实验。作者设想，地球人在外星人带来的灾难面前，被迫放弃人类世界框架，采纳基于黑暗森林图像的宇宙关系法则。新的世界框架必然造成人性的重估，催生新的认知方式和道德原则。刘慈欣以社会学家的严谨态度，一步步地将全部过程展开。这既是从休谟到罗尔斯的普遍人性论批判的延续，也冲击着传统的看文学的方式，因为在刘慈欣这里，人物塑造和情节设置取决于世界设定，“世界”才是他要描述的主要对象。

Abstract:

Three Bodies is a thought and literary experiment to change the world frame. The author envisions that the human race, in the face of the catastrophe brought by the aliens, is forced to abandon its old world frame and adopts the law of cosmic relations based on the image of Dark Forest. The new world frame inevitably causes a reassessment of human nature, giving rise to new ways of perceiving and moral principles. With the rigor of a sociologist, Liu Cixin unfolds this process step by step. While continuing the critique of the universal human nature from David Hume to John Rawls, it revises the traditional way of understanding literature, because in Liu Cixin’s work, both characterization and plotting depend on the world setting, and the world is the main object to be described.
