Conceivability is not invoked for logical statements, or mathematical statements about abstract objects. But zombies seem to be concrete rather than abstract objects. Similar to pink elephants. It would be absurd to conjecture that pink elephants are mathematically impossible. (More specifically, both physical and mental objects are typically counted as concrete.) It would also seem strange to assume that elephants being pink is logically impossible. Or things being faster than light. These don’t seem like statements that could hide a logical contradiction.

Sure, I agree about the pink elephants. I’m less sure about the speed of light.
