There is something about a man that we need a challenge to overcome. There is a hill that must be taken, a mountain climbed, a hot rod built. We have to walk the Appalachian Trail. But what if you were without limits to challenge. What if the constraining bonds were society and challenges against it? Obviously Superman and Tyler Durden are on opposite sides of the fence. Superman upholds civilization against all odds while Tyler is an incorporeal mad bomber & cult leader who leads the disaffected and bored against a society that they feel holds them back from being supermen on their own.
We're the middle children of history, man. No purpose or place. We have no Great War. No Great Depression. Our Great War's a spiritual war... our Great Depression is our lives. We've all been raised on television to believe that one day we'd all be millionaires, and movie gods, and rock stars. But we won't.
What do the challenges in our lives mean? When I was at Castle Peak, what the mountain meant was far more than what the mountain was. What is life without something to overcome?
