When things descend into the canon of indoctrinated greatness, they must surely be freshly re-evaluated and qualified over time, otherwise we end up teaching things in text books in a wrote fashion that are never re-evaluated, all things are in flux, and it tires me to see people repeating the opinions of others or books without qualifying them themselves. The great canon of literary works is like this just taught wrote fashion and each person learns the dogma and indoctrinates someone else with it, noise transference.
