Full Idea
Lewis's concrete worlds give a better account of modality (than fictional worlds). When I learn that a man like me drives a truck, I gain evidence for the fact that I can drive a truck.
Gist of Idea
Concrete worlds, unlike fictions, at least offer evidence of how the actual world could be

-: 'Philosophical Studies' [-], p.7
A Reaction
Cf. Idea 12464. Jacobs still rightly rejects this as an account of possibility, since the possibility that I might drive a truck must be rooted in me, not in some other person who drives a truck, even if that person is very like me.
