@freemo Doctor Freemo, How do you counter with someone who disagrees with the idea that wikipedia is a legitimate source of knowledge? So far as I can see, this kind of skepticism does have some point, not only because the editors of wikipedia may not qualify for the task, but also because wikipedia is getting more politicized than ever. In fact the problem is not limited to wikipedia, all the major institutions, the media, the academy, the ones who were supposed to reveal and pursue the truth, have all lost their credibility, and along with it the public trust. Even the very notion of objective reality itself has been under vicious attacks from these institutions supposedly protecting them. While I feel sorry for people buying into the fake stories promoted by certain politicians and writers, I can understand the deeper reason why they are behaving that way, because who is there to trust when the mainstream media and academy no longer care about the truth and are campaigning against you?
I think all this boils down to this question: In this ultra politicized world when the old authorities have become fraudulent and corrupt, how do we prove that those external sources we invoke are legitimately true? would that take too much effort? Yes, the task always falls on the individual to use his own reason and independent thinking to decide what is true, but our energy are limited and, we don't have so much time to define every concept or prove the credibility of our invoked external sources.
