In John Knittel's book Via Mala, there is a passage where one of the protagonists meditates about cleaning. He points to the fact that endless cleaning and dusting is the refuge of those small people who put emphasis on the trivial and overlook the important and meaningful. He compares these individuals to the famous physician Carylle, who is looking for microbes and misses big, more important things.
Can anyone help me with the exact wording of that paragraph?

I worked the Internet over pretty good, with all the searching tricks I know, but could find no help for you there.
Just checking to say "I tried."
