Quotes from Serial Experiments Lain (TV, 1998)
Chisa Yomoda: There was no reason for me to stay in the real world any longer. In the real world, it didn't matter if I was there or not. When I realized that, I was no longer afraid of losing my body.
Masami Eiri: Mankind is a creature that no longer evolves, is it not? Compared to other animals, the cancer rate in man is exceedingly small. One theory says that man is a neoteny and is no longer able to evolve. If this is true, then what an absurd creature man has evolved into. Not knowing what it is that drives them they keep their bodies merely to satisfy the desires of the flesh. They're worthless, don't you think? That's all mankind is.
