A reasonable argument is (tentatively defined as) an argument which hasn't been shown to be fallacious or based on erroneous premises. The conclusion of such an argument is considered a reasonably sound opinion and may be written as if factual, following the policy of Reinforcement by Contradiction.
This was going to be a redirect to Issuepedia:Reasonably sound opinion, but then I realized it was more of a separate concept. Or maybe it isn't. Any opinions on this? --Woozle 14:15, 27 March 2007 (EDT)
