To acquire the habit of reading is to construct for yourself a refuge from almost all the miseries of life. — W. Somersat Maugham, Books and You
The walls of books around him, dense with the past, formed a kind of insulation against the present world and its disasters. Ross Macdonald
I really like the image of my library as a mighty fortress in this quotation. It is included in many collections of quotations but none included the text source. One site hinted at The Underground Man where I found something similar.
The walls were lined with books, many of them in foreign languages, like insulation against the immediate present.
Perhaps he liked the image well enough to polish and reuse in another novel. Possibly it’s an example of a quotation being modified as it’s passed around. I am happy to have a bit of literary research to justify a binge reading of Macdonald’s work.
