Of course there are dozens of different theories about what it all means, although space aliens, mad scientists, and they're-all-dead-and-this-is-the-afterlife seem to be the most popular by far. During the first season, I inclined toward the Purgatory theory. Everyone seemed to have issues they needed to work out before they could find whatever peace they were looking for, not to mention dark secrets, which their adventures on the island always seemed to call up one way or the other. With Season 2 and the emergence of the Dharma Initiative I swung over into the science experiment camp. But the more we learn about the Others the shakier that theory seems to me, although I'm still not ready to abandon it. Perhaps there is something deeper going on for which the Dharma Initiative is merely a front -- something so dark and secret that most of those who work for the Initiative have no clue what it's really all about. They honestly think they are trying to save the world, while those in charge have an entirely different motive. Or perhaps some of them have caught on and rebelled, which would explain why there seem to be two groups of Others. Some might still be dupes and true believers, while others are desperately trying to undo the whole project. Except that would really mean three groups: the dupes, the rebels, and the people in charge. What does everyone else think?
