  • We will look at his list of rules. What are they rules of? They are not rules of good method - how to think in order to get knowledge. So what are they?

I think Lewis Rule of Resemblance "one possibility saliently resembles another. Then if one of them may not be properly ignored, neither may the other" (556). is the one that makes the most sense to me. When he talks about the possibility of winning the lottery he says that my chances of winning or someone else' are similar and my chances of losing is similar to everyone else' chances that being why the possibility of me winning or losing is just as likely and also in comparison to any other individual participating in the lottery. In regards to the Rule of Actuality. I don't understand whose actuality counts because at first he says that the subject and ascriber's actuality are the same so there is only one actual world(top of page 555) then later he says that there is a difference and it is the subjects and not the ascriber's actuality that matters (bottom of page 555)???
