Well, discussion can go on forever, when few are enlightened with the facts. Check in on the discussion thread at TCP PDF entitled Libby juror supports pardon
Hey, I was a major fan of the x-files (until mulder left), but I am seldom in doubt about the differences among fact, fiction, fantasy, proof, evidence, truth, and falsehoods.
Proof is found in repeatable demonstration. Evidence is when there may be a relationship that comports with occam's razor (see below). The item of evidence is often a fact. A fact is something that exists in 3 dimensions at the present point in time. A proof is when one or more facts are unalterably related to one or more facts.
My memory evidences to me that it was a fact that I made love to cate blanchett, but this is actually a fiction (any non-fact that stands in for a fact) that you suspect is a fantasy.
