I love Ian Banks' books because he frequently takes the time to imagine a utopia, not as an allegory for why utopias are impossible (and in the extreme sense they are, we all get that, it's not interesting) but rather as an exercise in seeing how close one could get to a society with real freedom and few contradictions.
I think it's a good exercise. OK fine so how would a world without hunger or unwanted suffering work?
He took on the topic of gender in this spirit and it's glorious.
