Answer:
Including non-western literary works, and literary works authored by women would benefit the quality and depth of the post-secondary education system.
Students should be able to study, analyze, and learn from many different literary works: both from the western world and from outside the western world, and both from works made by men, and from works made by women.
The reason is simple, this inclusions would enrich the literary perspective of students. It would make them better academics, and perhaps, better authors as well.
