M. John Harrison in an unpublished interview from way back before Sunken Lands… came out:

If people didn’t have Joseph Campbell’s artful wish-fulfilment (sic) fantasy to place them at the centre of events and keep them enchanted with their own reflection, they might dump their wish to be princess of all they survey, and instead channel their dissatisfactions into making a better world for everyone.

This line of thinking is why I am a grateful reader of Harrison’s and… not a Campbell fan.
