Lewis encourages us to "crush Bulverism" in order to let reason play an effective part in human affairs. Reasoning is important because we "can only find out the rights and wrongs by reasoning - never by being rude about your opponent's psychology."
I found a major correlation between today's lesson on Bulverism and yesterday's "Meditation in a Toolshed." Bulverism is the exact opposite of the humility that we are urged to adopt. The only way we can look both along and at the light is by making ourselves humble enough to acknowledge the validity of our opponent's arguments. This doesn't justify becoming a doormat and accepting all that is thrust upon us. It simply means that we need to be more open and discerning with what others might have to say to us. God can show Himself to us through the people in our lives, but if we automatically shut out everyone who attempts to approach us, we will never hear His message. Passion in argumentation is important, but it comes second to respect. There is a fine line between being passionate and self-righteous.
