Next, focus on the ontology of documentary, the creation, the dissemination and the acceptance level, making a comprehensive analysis of the authenticity of documentary in the process of creation based on the "horizon fusion" theory.Second, research on the authenticity of documentary in documentary history of the world, and discuss different view about authenticity based on "pre-comprehension". With reference to different creative mode and features of foreign classic documentary, combing different comprehension about the authenticity of documentary, and discussing the domestic "prejudice". This chapter makes a comparative analysis for the same period of documentary creation of both the domestic and the abroad, points out the "dislocation" and "lag" of domestic theoretical comprehension.Third, take "effect of history" theory as the breakthrough point, explore the openness, narrative and sentience with the development of documentary creation, and point out that it is a blending process. And emphasize the trend of comprehension:don’t ignore the "original intention" of the authenticity, both the "degree" of subjective creation and the "humanities".So, the paper on the basis of the history of documentary in the longitudinal direction, analyzes the creation mode and type on the lateral, and coupled with creation value and ethics, intended to have a three-dimensional comprehension for the authenticity of documentary. |
