The Theory of Factual Evidence states that theories can be proven true if a sufficient amount of factual evidence is provided. All ways of proof involve the assumption that this theory is true.

Clear and convincing proof means that the evidence presented by a party during the trial must be highly and substantially more probable to be true than not and the trier of fact must have a firm belief or conviction in its factuality.
