Amazingly, Cardinal Cormac Murphy-O'Connor, Archbishop of Westminster, has , in the same speech in which he conceded Christians should "respect atheists", has suggested that he thinks it is dangerous to be governed by reason alone.
He was saying that societies ruled only by reason "were like those created by Hitler and Stalin".
It is hard to believe that someone who spouts such nonsense is permitted to hold a position of such power and influence. Using reason to govern our behaviour is a far cry from what Hitler and Stalin did. They were both distinctly unreasonable.
Darth Cormac seems to think that reason is a path to the dark side, yet being a Catholic he believes he literally consumes human flesh and blood.
Only someone who believes in an all-knowing sky-faerie could think that reason leads to being unreasonable. Go Darth!
