The exercise of imagination is dangerous to those who profit from the way things are because it has the power to show that the way things are is not permanent, not universal, not necessary. Having that real though limited power to put established institutions into question, imaginative literature has also the responsibility of power. The storyteller is the truthteller.
We will not know our own injustice if we cannot imagine justice. We will not be free if we do not imagine freedom. We cannot demand that anyone try to attain justice and freedom who has not had a chance to imagine them as attainable.
- Ursula Le Guin, The Wave in the Mind
