What does Montag learn from the woman who gets burned with her book? include a quote from the book

This woman had a tremendous impact on Montag.  She burned
with her books.  When he is talking with Mildred about it later, he says "There must be
something in books, things we can't imagine to make a woman stay in a burning house,
there must be something there.  You don't stay for nothing." (pg 51)   Mildred tries to
say that the woman was simple-minded and that it is water under the bridge.  Montag
knows that the experience will last him a lifetime. He cannot put it out of his mind. He
goes on to explain that for the first time he realized that a man wrote the books  He
had to think them up and put them down on paper, and then he came along and in two
minutes burned it all up and it was over.  It seriously bothered
him.
