Why does Swift refrain from explicitly stating he is the author of the book?

Swift refrains from explicitly stating that he is the author of "Gulliver's Travels" to enhance the narrative's authenticity. By presenting the story as a true account of Lemuel Gulliver's adventures, he invites readers to engage more deeply with the text, blurring the lines between fiction and reality. This technique allows Swift to explore complex themes and critiques of society, politics, and human nature without the immediate bias that might come from being identified as the author. This narrative style fosters a sense of immersion and credibility, prompting readers to consider the implications of Gulliver's experiences as reflections of their own world.
