Fragment of a discussion from Course talk:Phil440A

One of the problems I find with the rule of attention is it's relationship with Lewis' other rules, particularly the rule of conservatism. If two people are in conversation and one of them says something that seems to be against common knowledge, such as saying that the world is flat, which of these rules would outweigh the other? Does the rule of conservatism only hold if both people in the conversation share the same idea of common knowledge, even if one person seems to be obviously wrong? I would assume in this case that the rule of attention would outweigh the rule of conservatisim. In this situation, the person claiming the earth to be flat would have to argue their case, and the other person would have to seriously consider their argument. The interaction between Lewis' many rules seems kind of vague to me, this may not be the best example, but in some cases it doesn't seem clear which rule takes priority over the other.
