Perhaps we can reconsider those curious things with complexity thinking, for under a chaotic, compositive, interlaced and interconnected circumstances, everything may happen; Perhaps changing a point of view can enable us to understand these products of blazing, rushing and chancing. However, things are not that simple, for complexity thinking will lead us to observing and seeking the hidden sequences and changing regulations.

正值此时或许我们可以借助复杂性理论重新审视那些人类心灵活动最敏感也最丰富的情感世界中不断涌现的新&东西&，以混沌、综合、交织和相互联通的思维重新理解那些激发、涌现和偶然的现象，仔细观察和寻找那些隐藏其后的潜秩序，借助那些星星点点的暗示，也许能够引导我们窥测事物发展的真实轨迹。

Moore attempted to prove that "I know I am not deceived by the evil demon" with the aid of the neo-commonsense realism, while Putnam drew support from the semantic externalism to attempt to prove that "the supposition of brains-in-a-vat is self-refuting", however their arguments are doubtful.

摩尔借助新常识实在论试图证明&我知道我没有被恶魔欺骗&；普特南则借助语义外在主义试图证明&缸中之脑假设是自我反驳的&，然而他们俩人的论证都是有问题的。

Using the image of comparative literature on the theory and methodology, this paper cards Western image of the ancient Chinese before the Qing Dynasty and analyzes the characteristics of the traditional mode of thinking and collective imagination at the beginning. Then, connecting the above features, it focuses on the image of the United Kingdom in travel notes of the Qing Dynasty and analyzes the role and significance of the travel notes and the officials in the formation of "the image of the United Kingdom" in the Qing Dynasty. That is, travels text is a kind of cultural narrative, Travels with intertexuality completed the social collective imagination. As the Qing Dynasty Construction of the image, officials try to deviate from the traditional Chinese collective imagination. By virtue of British image of self-desire, they state their self-desire and reflect on their own culture.

本文借助了比较文学形象学的理论和方法论，首先梳理了清代前中国人眼中的&西方形象&，分析出中国古人看世界的文化心理和传统思维模式特点，接着结合上述特点解读清代游记中的&英国形象&，并分析出清代游记和清代使官在英国形象生成中的作用和意义：游记文本是一种文化叙事，游记的互文性写作完成清代人对英国的集体想象；清代使官作为形象的建构者，试图背离中国传统的集体想象，他们借助英国形象言说自我的欲望、反思自身的文化。
