“ To commit the act of felo-de-se is a form of delusion. You see, my love, to leave one's life unfinished implies the possibility of success. What is left unlived may contain the potential truth one always seeks. Those who kill themselves do so with the conviction that they would have reached that truth eventually had they lived to the proper end. They die in the illusion of hope which in a way keeps the rest of us alive. Reason, therefore, for not committing suicide. ”
