Proposal: Soundness and Completness

Self-killed. — Quirck

Adminned at 12 Jun 2013 07:25:25 UTC

Append to the rule “Truths”:

A statement cannot be added to Truths if it directly contradicts another statement. The contrapositive to any statement in Truths is False. There exist statements which are neither provably True or False.

Making sure our list of Truths abides by Soundness, and introducing the problem of completeness.

against On account of how contrapositives of True statements are True as well.

against Per RaichuKFM. Also, I don’t think the third part is necessary (as long as we don’t make up a rule stating “everything which is not in the list of Truths is false”). And I don’t like the first part.

Ienpw… if a contrapositive of a true statement is false, then we’ve broken logic. It’s a bit early in the game for that, isn’t it?

Also, it never specifies it must contradict another statement in truths, and every statement directly contradicts its opposite, so it would make Truths unusable.

against  Yeah - I meant the negation or converse, not the contrapositive. I guess my reasoning wasn’t so sound.
