How reasonable is the way we speak about causality? Say a person catches a cold. The cause of that cold might be said to be the effect of the cold virus; or it might be said to be the contraction of the cold; or the failure to prevent the contraction of the cold; or the presence of the virus or of the victim wherever it was contracter; or whatever brought either of them to that place; etc. For most things (leaving aside the thorny issue of free will), things that happen are caused by other things. So when we speak of causality, does it make any sense to say that some causes caused whatever we're talking about, and to ignore other, more proximal or more distal causes?
