I don't remember reading anything by him, but... [googles] Yeah, I guess so, even though IMO Drescher's way of putting it makes it clearer (than the English Wikipedia's description of Lewis's view) that Egan's Law isn't violated. (Conversely, I think that Drescher's discussion of space-time is much worse from that point of view -- “static” means a constant function of time, not just a single-valued one! I thought that after Zeno we had cleared that up; a much better way to describe B-theory AKA eternalism AKA block time is this.)
