 Lewis 1986 pp 195–197 argues that a version of the argument from concern can be at least raised about any realist possible worlds theory account of possibility: and, he would likely add, any fictionalist account as well. If Humphrey is unfamiliar with possible-worlds-jargon, he may not take himself to have any concern with possible worlds when it hurts that he could have won. Of course, theorists may wish to offer reasons why some accounts do better in respecting the facts about what we are concerned with than others. (Or indeed give general reasons why no argument from concern is a challenge to theories of possibility.)
