You've probably seen the comic Dilbert, by Scott Adams, around in some fashion. But back in 1999-2000, there was a short lived TV series. In the second season, episode 3 - The Shroud of Wally, Dilbert explores the meaning of life after dying... not once, but twice. However, before Dilbert dies the first time, he has the following conversation with his mother (Dilmom) who believes everything she hears.
Dilmom: You have to believe in some things without proof Dilbert. Otherwise, life will appear meaningless.
Dilbert: Maybe life is meaningless. Did you ever think of that?
After dying, Dilbert follows "the light" to a cubicle. A theme that he reverberates throughout the episode... that he thought there would be more to the afterlife. Hence concluding that nothing really matters.
At the end of the show, Dilbert comes to terms with this through a conversation with Dogbert.
Dilbert: Is the answer out there (points to the sky) or in here (points to his head). Is everything simply a manifestation of consciousness? Or is there another actual level of existence? A dimension parallel to or beyond the one we live in now.
Dogbert: It is all part of the big illusion that we perpetuate on ourselves and is in turn perpetuated on us. Like the rocketship or the Shroud of Wally. When we believe, we engage the illusion. When we stop believing we shatter the illusion and shatter ourselves in the process... because we are part of it.
Dilbert: Maybe your right. Maybe the mistake is in making distinctions. Out there, in here. Life, death. It is all the same illusion.
What do you think? Is it all an illusion?
