"What I do not want to write is didactic political tracts"

In this quote, Joan D. Vinge is revealing her viewpoint on the kind of writing she does not wish to do. She is stating that she does not wish to compose didactic political systems. A didactic political system is a piece of writing that is planned to teach a moral or political lesson. It is typically written in a preachy or condescending tone, and is meant to convince the reader to adopt a specific perspective. Vinge is likely revealing her choice for writing that is more imaginative and creative, instead of writing that is meant to be educational or persuasive. She might likewise be expressing her desire to write stories that are entertaining and thought-provoking, rather than stories that are merely attempting to make a political point.
