There’s been lots of good stuff written recently on causation by omission. Does anyone know any equally good work on causation of omissions? Here’s two puzzle cases that I’d like to know what to think about.
Killing a Would-be Stranger
Smith is planning to disappear from his community. He has the tickets to fly away, the false passport and documentation to start life in his new country, and even a job lined up in his new home. He’s sent all of his belongings on ahead to his new home. As he’s heading out to the airport to fly away, Jones kills him and throws his body into the sea where it’s never found.
Question: Is Jones’s killing Smith the cause of his not being in his old community.
Argument for yes: Jones’s killing Smith is a cause of his being at the bottom of the sea. His being at the bottom of the sea is a cause of his not being in his old community.
Argument for no: No counterfactual dependence of his not being around on his being shot by Jones. The second causal claim might be false. (Transitivity of causation is dubious.)
Slacking Off
I am meant to teach a class at 3. Instead I decide to go watch an afternoon baseball game. The game starts at 1, so I leave home at 12.30 to go to the game. I’m not in my class at 3. I think it’s pretty clear that my deciding to go to the ballgame is a cause of my not being in my class at 3.
Question schema: Is my being in the ballpark at t a cause of my not being in my class at 3.
I think the answer is pretty clearly no for t = 3, since then my being at the ballpark constitutes, rather than causes, my not being in class. But what about for t = 2:59? If I hadn’t been in the ballpark then, I probably would have been teaching. But wait! That looks like a backtracker conditional – if I hadn’t been in the ballpark then it probably would have been because I wouldn’t have decided to go to the game. If I hadn’t been in the ballpark at 2:59, it probably would have been because I had to leave on an emergency just before then. (Maybe I had a heart attack and was whisked away in an ambulance.) So I don’t know whether the relevant causal counterfactuals are true.
