The lines at the end of "A Tale of Two Cities" are equally magnificent and possibly even more memorable.
"It is a far, far better thing that I do than I have ever done. It is a far, far better rest that I go to than I have ever known". To understand the meaning of those words you would have had to have read th book or seen the movie. Did you?
The middle of "A Tale of Two Cities" is quite equal to the beginning and end. Then of course there is "Call me Ismael". Words that are so memorable are priceless in a story about a man with a wooden leg and a whale.
