There has been some discussion lately about logic and the rules of logic as they apply to describing the real world and events contained therein. I believe this was the focus of study of both Bertrand Russell and Ludwig Wittgenstein. If A=B and B=A then by comparison what is C rendered? And if the answer is both A and B, then equal weight has to be given to all propositions thereafter. And thus they remain forever unsolvable and undefined.
Is mathematics an opinion?
