Final answer:
The contribution involves a critique of the narrative voice in Orwell's 'Nineteen Eighty-Four' as a way to explore the themes and social and political impacts of the novel, and it shows how authors can draw on external events and historical moments to deepen textual analysis.
Step-by-step explanation:
The author's discussion of George Orwell's Nineteen Eighty-Four contributes to the text by offering a critical examination of the narrative's voice and how it reflects underlying societal concerns, such as censorship and propaganda, leading to a deeper understanding of the text's themes, characterization, and point of view. By relating the narrative voice to Orwell's depiction of a dystopian society, the author accentuates the political and social ramifications of the literary work. The context provided by the author, including both historical and contemporary influences, enables readers to see how Orwell's novel not only echoes the control experienced during wartime Britain but also continues to resonate with modern day issues of governmental authority and individual liberty.
Furthermore, the mention of Gwyn Garrison's textual analysis shows an example of how authors can extend their analysis beyond just the text, bringing in external events and real people. The discussion of Orwell's work thus supports a wider conversation about the impact of literature on societal structures and individual consciousness, and how various methods of study can reveal different layers of understanding of a literary work.
