"What I have most wanted to do through the past ten years is to make political writing into art."
"Why I Write" is a short essay written by George Orwell and published in a magazine in 1946. It is structured, like much of his work, in a direct and straightforward manner. Orwell believed writing and language should be clear and to the point, something he discusses at greater length in "Politics and the English Language" (1946), which I would suggest reading. Orwell begins his essay with a brief personal history, discussing his family, how he always felt he would be a writer, and his early forays into writing, many of which were poems. He quotes from Paradise Lost and discusses how literature impacted him and influenced his own writing. As the essay progresses, he mentions his first book, Burmese Days, his motives for writing, and how the politics and history of his time gave him subject matter and made him see the importance of political writing.
Whether this structure, word choice, and progression is effective is up to the reader, but I would argue that it works well to convey his ideas and to take the reader from point A to B with admirable clarity and insight.
