A fact is a factum, a thing done. It is something accomplished: a deed performed, a happening occurred, an event enacted. Unlike truths which are untouched by time, facts are stamped with the character of the past. As the past is unchangeable, so the facts are indisputably what they are. To dispute a fact is to wrench it from its pastness and hurl it before the future. The irony of every ostensible factual dispute is that the object in dispute is no longer a fact at all.
