The ego loves to take sides, and the longer and more vigorously it justifies its side, the more it feels like this is surely truth. Soon my truth easily morphs into the truth and even the only truth. We end up not with orthodoxy but with egocentricity. This is invariably what happens when we have not been exposed to perennial philosophy, when we are not taught how to distill the big patterns out of the momentary arguments where everyone takes sides, when we cannot distinguish the small, separate self and the self created by God and one with God, from all eternity.
-Richard Rohr, Center for Action & Contemplation
