No violence intended to the intentions of the original poster, but: It wouldn't work for me. No surprise I'm sure :-). In left hand column: Number 2 is too cut and dried. "Shown to be faulty" has all sorts of auumptions in various contextst. BUT #3 ythey say "principles of reason", which may just possibly be able to be worked with BUT then explain it with a completely invalid example - "More reasonable" is never a guarantee of fact or truth. Neither is "more supporting evidence", even if "supporting" can be agreed on. Number 4's 4 points sound to be more written for a formal debate than for a= n attempt to elucidate truth. And their conclusions at bottom right feel like what the page is really about. viz an attempt to make a "rule set " that will let you declare your opponents tactics illegitimate and so show that they have lost the argument= .. Mayhaps too harch, but I can't feel good about it even at a relook "just in case". Whatever.
