If we inquire into the reasons for this great change, we receive these answers: political philosophy is unscientific, or it is unhistorical, or it is both. 若追问这一巨变的原因，我们会得到如下答案：政治哲学不科学，或不历史，或既不科学又不历史。
According to Fredric Jameson, nostalgic movies create a new past and convey a "pastness" that has nothing to do with history by a unhistorical collage of images about the past. 根据詹姆逊的看法，怀旧电影借助非历史地拼凑各种有关过去的形象，创造出一种新的过去，传达一种非关历史的“过去性”。
