Her essay celebrates how the Maybeck house allowed the "inhabitants" to fulfill the total aesthetic experience. Therefore, the spatial house becomes the stage, the residents become the actors.LeGuin's descriptions of fictional material culture, cities, streets, parks, houses,
clothes, music, food, agriculture, rocketships, are all secondary but well drawn and appealing.
Nature is well described too.
Her center of attention however is personal, social, political - in a broad sense.
Or to my examples earlier, "Wonderland" is the stageÃ¢â‚¬â€œÃ¢â‚¬â€œthe mental space the reader "lives in"Ã¢â‚¬â€œÃ¢â‚¬â€œwhile Alice and her adventures are the center of attention, the actors, the inhabitants.
Michael Pollan has a good line about the process of writing.... 'The subject is the landscape, the story is the path that leads through the landscape.'
I believe Le Guin is discussing the relationship between spaces and their occupants, how she sees it idealized in physical architecture, and how she's reflected that relationship in her mental spaces of literature.
