We say we like consistency in others and ourselves (safer? more predictable?), but really it's our contradictions that make us fully human. And where the contradiction springs is where we find our greatest strengths.
Maybe the most admirable among us, are not those without contradiction (because we know this is a false face, a bald lie, and only the shallow mask of the hypocrite), but those who are fully comfortable with all of their contradictions fully on display.
We are all of us crucified on the cross of contradiction. It's the crux of the human story.
