In this post, Carolina Sartorio discusses her recent article in the Causation in War Symposium in Journal of Applied Philosophy on how degrees of causation can (and cannot) bear on liability to harm.
The recent literature on the ethics of war draws heavily on the concept of causation. Your liability to be attacked during a war, some suggest, depends on the extent of your causal contribution to an unjust threat. Prominent theorists like Jeff McMahan and Cecile Fabre embrace a principle of civilian immunity on this basis: they claim that civilians (unlike soldiers) aren’t liable to attack because their causal contributions to an unjust war are typically very minimal. These ideas rest on an important assumption: that causation comes in degrees. But, is this assumption true? In my article, I argue against it. I claim that the appearance that causation comes in degrees is an illusion that can be explained away.
