Jean-Paul Sartre produced plays and novels like The Respectful Prostitute (1946), which explored racism in the American South. These works were criticized as too polemical to count as good literature. What might in the present day culminate only in a Twitter fight led Sartre to publish a whole book defending his practices, called What Is Literature? (1946).
In the clip below, Mark Linsenmayer from the Partially Examined Life Philosophy Podcast explains Sartre's view, outlining both how strange it is and why you might want to take it seriously anyway. In short, Sartre sees the act of writing fiction as an ethical appeal to his reader's freedom. The reader is challenged to hear the truths the work expresses, to understand and take action on them. More directly, the reader is challenged to read the work, which involves a demand on the reader's attention and imagination to "flesh out" the situations the book describes. The reader takes an active role in completing the work, and this role can be abandoned freely at any time. If a writer creates an escapist fantasy, the reader is invited to escape. If the writer produces a piece of lying propaganda, then the reader is being invited to collaborate in that fundamentally corrupt work.
So if writing is always an ethical, political act, then Sartre shouldn't be blamed for producing overtly political work. In fact, writers who deny that their work is political are dodging their own responsibility for playing haphazardly with this potentially dangerous tool. Their work will produce political effects whether they like it or not.
