I agree with this criticism, but also think that context is required in order to determine the presupposition included in a complex sentence. To show the context role in fixing the utterance truth-conditions in those cases, this paper introduces the Kripkean anaphoric account on presuppositions （section 2）, and then criticizes this approach because it is very restrictive （section 3）. The paper concludes that to solve those difficulties, one should appeal to a two-dimensional framework, including a new parameter that focuses on the sentence according to the concrete features of the context： the speaker＇s point of view （section 4）.展开更多

Analyzing the Dickinson＇s poets and other writers＇ or poets＇ works in different contexts of classical inheritance, and philosophical thought. To break up the text of the solitary, put the text in the associative network of readers＇ experience, take the text as the link of the writer and the readers, and connect the inheritance, experience of the writer and the readers＇ reading. Use the method of intertextuality to interpret the non-meaning of the text, then to understand the significance of existence of Dickinson＇s works. This thesis mainly studies from the following aspects： It reveals the intertextuality of the works of Dickinson and Shakespeare, Isaac Watts and some Romantic poets from the point of classical context. By studying from the point of Transcendentalism and Existentialism, It explores the intertexutality relationship between Dickinson and Emerson, Thoreau as well as other writers. It also disserts the significance and influences of Dickinson＇s works through comparing and analyzing the intertextuality between Dickinson and Li Qingzhao, Xi Murong, as well as Annebaby.展开更多
