NON-FALSEHOOD

except in trivial cases, (largely the a priori or tautologies), we cannot know we speak the truth, we can only warranty that we have done sufficient due diligence to not knowingly speak a falsehood.

So we can say that all certain knowledge consists of falsehoods, and all that we conventionally claim is true, except for trivialities, consists only of truth candidates.

Of those truth candidates we can only claim that they survive in the tests of hypothesis(survival of plausibility), theory(survival from criticism), and law(survival in application), and tautology (indifference).
