The issue then comes up of how to get rid of Bulverism. There is still truth and reason to Bulverism, but "until Bulverism is crushed, reason can play no effective part in human affairs." Each side uses reason improperly for Bulverism. And until it is completely gone we will always have bad arguments.
I really like the quote: "A theory cannot be accepted if it does not allow our thinking to be a genuine insight, nor if the fact of our knowledge is not explicable in terms of that theory." I think many people accept theories that they do not think out, or apply their own knowledge. This is evident when I am talking to a friend about current issues and they only facts they know about a certain subject are ones somebody else told them. They did not research on their own. It's very frustrating. So, I really like that C.S. Lewis makes the statement that a theory cannot be accepted if we don't genuinely think about it or apply knowledge.
