2. Why is Levine skeptical about the possibilities of closing the explanatory gap? What reasons does he give? Are they convincing? Why, or why not?

He now endorses strong representationalism—the idea that experiential features, such as seeing red, are representational features. Could Jackson be right? Could experiential features really be representational features? Why do you suppose Jackson adopted this position? Does he manage to save physicalism? Why, or why not?
