"We find it difficult to conceive of evil and beauty together. The fear of the beautiful fay that ran through the elder ages almost eludes our grasp. Even more alarming: goodness is itself bereft of its proper beauty. In Faërie one can indeed conceive of an ogre who possesses a castle hideous as a nightmare (for the evil of the ogre wills it so), but one cannot conceive of a house built with a good purpose – an inn, a hostel for travellers, the hall of a virtuous and noble king – that is yet sickeningly ugly. At the present day it would be rash to hope to see one that was not – unless it was built before our time."
