"I went to the woods because I wanted to live deliberately, I wanted to live deep and suck out all the marrow of life, To put to rout all that was not life and not when I had come to die Discover that I had not lived."
- Thoreau
I think that this quote is similar to "I go to seek a Great Perhaps" said by Francois Rabelais. They're both talking about going elsewhere to really live their lives. It also relates to the Keating quote from the post before this one. They relate in the way that they both mean that they can't truly be themselves and be happy unless they're somewhere else. Keating goes to dreams, Thoreau goes to the woods. "to live deep and suck out all the marrow of life" I interpret as to mean that he wants to live his life to the fullest. "To put to rout that was not life and not when I had to come to die Discover that I had not lived" this means to me that Thoreau was a bit afraid (if I could call it a fear) of coming to his death and realizing that he had not lived in the way that he could have really lived. This quote also has a bit of a "carpe diem" theme going on, which is why I think it was very appropriate for The Dead Poet's Society.
