res ipsa loquitur

the thing speaks for itself

Notes

A phrase from the common law of torts meaning that negligence can be inferred from the fact that such an accident happened, without proof of exactly how. A clause sometimes (informally) added on to the end of this phrase is sed quid in infernos dicit ("but what the hell does it say?"), which serves as a reminder that one must still interpret the significance of events that "speak for themselves".
