"In my novel, the peaceable aliens are forced to learn from us how to commit war, while we learn nothing from them. I present this as a tragedy. I understand that the same situation in Avatar is seen as a victory. 'White man teach simple native important lesson: violence solves all problems.' Uh-huh." - Author Ursula Le Guin talks about her novel The Word For World Is Forest the plot of which is strikingly familiar to James Cameron's Avatar.
