This was an incredibly interesting post. Suicide as a concept and act is something that should be explored more in the mainstream, as it's something that most people simply brush off as being unacceptable (see: DanQ's comment). theadvancedapes: Have you ever read The Stranger or The Myth of Sisyphus by Albert Camus?
The both intertwine Absurdism with the concept of suicide. The Myth of Sisyphus is a philosophical essay that poses and answers a pretty specific question asked by Camus: Should the fact that life is meaningless be addressed by committing suicide? The Stranger isn't quite so blunt and to the point as it's a short novel, and also my favorite work of his. The same concept and question posed in The Myth of Sisyphus is posed here, but to a much lesser degree. This novel attempts to explore the absurdity of living as opposed to delving into suicide.
That is an interesting concept. I have found that the apparent "meaninglessness" of life is something that atheists must encounter frequently when discussing life with religious people. For me, I just try and find meaning in my own passions, interests, friends, and family. You have to make your own meaning since the universe is indifferent to your existence.
