Shaw

"The reasonable man adapts himself to the world. The unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man." [George Bernard Shaw]

MacIntyre

"What deprives us of the knowledge of God also deprives us of self-knowledge: an indefinite capacity for distraction by external trivialities and a craving for self justification, so that we either do not attend to what is within or, if we do, disguise from ourselves our thoughts and motives." [MacIntyre, God, Philosophy, Universities]
