Rallying to the Cause

Why did the house go up in flames? Because it was made of wood, or because of an arson attack? Or because of an insurance claim? Choose one only. As you’ll all know, even way back in the day, solid ol’ Aristotle distinguished four levels of causality (ha, only four?): material, efficient, formal, final, if I remember aright. When it comes to certain tings, tho’, there can only be the one cause, for sure, and in single and peculiar instances things can be only their own cause, spinning round and round in their own wee tautology, and the curses of Sycorax on anyone who says otherwise. Like, for instance, the only cause of football hooliganism is the hooligans. So if there’s a footy match between two fierce rivals, and the security is really lax, and the barriers are all broken, and a horrid spat breaks out, then this is only and always attributable only to the hooligans, and to refer to any other level of causality is insensitive and perhaps wicked. And the historians, when they come to explain the hooliganism of the 1980's will doubtless also say that the only proper explanation is that there existed many hooligans. Anyway, please insert other examples as you see fit.
