"But the trouble with deep belief is that it costs something. And there is something inside me, some selfish beast of a subtle thing that doesn't like the truth at all because it carries responsibility, and if I actually believe these things I have to do something about them. It is so, so cumbersome to believe anything." - Blue Like Jazz
Does belief always cost us something? Is there a fine line between deep and shallow belief, where the depth makes us behave differently?
