I love a good conspiracy theory.
Conspiracy theories are a product of hope.
Organized, goal-oriented evil can be combated, so there is hope it can be thwarted. Still, it's a realistic one, and paradoxically enables us to reason out the bad things that happen in our world. I do realize that not all conspiracy theories are reasonable, or hopeful, or merit attention. What I also realize is that people equate conspiracy theories with insanity, ignoring that many of the greatest minds in history have been drawn to them. He concludes, then, that the only rational path is to believe.
