If I come into work with a black eye and people ask how I got it, it is perfectly reasonable to give a purely physical explanation, and say, ‘because the blood vessels in my ocular area are working overtime to repair damaged tissue.’ But they might feel a bit short-changed with that reply, because physical explanations don’t remove the need for personal explanations. They will probably find a different type of answer (‘because I stared too long at this guy’s girlfriend in the pub last night’) rather more satisfying. And they certainly won’t think that the former removes the possibility of the latter.
