Sultana's Dream

The main theme of the novel is that women aren't stupid and uninventive; they're just busy. If women ran the society, they would rise to the task, and they would do even better than men, because men are commonly limited by competition, whereas women tend to think and operate more as a group (these are the arguments of the novel, it seems). The sci-fi futurism of the novel is an argument that women could be elite and powerful if women were more empowered socially.
