"Good literature substitutes for experience which we have not ourselves lived through" Alexander Solzhenitsyn
The first quote means that in literature you can experience things you have never experienced in real life. This allows you to go where you cannot travel in real life such as the 1600's. This also makes think differently because you're traveling to a place you've never been.This is what the quote means to me.

The applies to my new book (King Arthur and the Knights of the Round Table) becuase i cannot experience medeival Britain or have a real sword fight. This also lets me see the way britains thought back then.
