Hi Nick, I assume you already know about the work Judea Pearl did to define a notion of causality in the context of inference on Boolean networks? I don't have citations on this, because I only learned about it recently in someone's talk, but I gather it is fairly widely known. Happily it doesn't claim to address all questions in which a given kind of word appears, so it probably contributed something concrete to answering a single class of them.
What is that old folk saying, said with a sigh? "Always a physicist, never a philosopher."
