There was proof in Madame Bovary and Don Quixote.
Here it is again in C & P, Park VI, chapter 2.
Proof that… Reading too much = Madness
In this particular part of Crime and Punishment, Porfiry is talking about Nikolay, the man who confessed to Lizaveta and the pawn broker’s murders:
He was full of fever, prayer at night, read the old books, the ‘true’ ones, and read himself crazy.
Here we are a year and a half later and eleven novels into the WEM list.
You’ll start watching for the signs, won’t you?
Because just like when the narrator in Don Quixote said, “… the lack of sleep and the excess of reading withered his brain, and he went mad”, I’m feeling rather tired, and I found out that Anna Karenina is 900+ pages.
