From defending Tautology to keeping silent

                
                Most of our models will be judged as "tautology", which means two things: First, in rhetoric, you using different words to say the same thing even if the repetition does not provide clarity. Second, it means a technical notion in formal logic, universal unconditioned truth, always valid("it's not even wrong"). See the explanation below.
Tautology [taw-tol-uh-jee] Show IPA –noun, plural -gies.
1.needless repetition of an idea, especially in words other than those of the immediate context, without imparting additional force or clearness, as in “widow woman.”
2.an instance of such repetition.
3.Logic .
a.a compound propositional form all of whose instances are true, as “A or not A.”
b.an instance of such a form, as “This candidate will win or will not win.”
Should you argue with him? Never bother to do that. There are too many papers judged as tautology got published. This is a trap. You should not try to discuss with those boring theories. They will disappear finally by themselves.
