The last thought that Fitz wrote in the book says “The mass of men lead lives of quiet desperation. What is called resignation is confirmed desperation.” The first sentence explains how Thoreau believes that most people a too raveled in their money to observe the world around them clearly. He thinks that most of them are not really happy but there view is clouded by money. So really they are desperate to escape that world, but they are quiet so because they do not know that they are desperate. The next part means that when they retire they are truly desperate because they will never do anything in there life that is meaning full. They just end when hey are behind and they never get anything done besides making money. But who knows, this could all mean something else that Thoreau is hiding from us or maybe there is an other meaning that is hidden under the cryptic writing of Thoreau.
