As much as i like this forum I have a question, what us the difference between a fact and an opinion? According to feynman, one should never trust authority. Therfore any truth is always subject to scientific debate, and as soon as we are told a concesses is true, by the very fact of being a concenses we should debate the facts. I am of the opinion that we all have opinions, but that majority opinions alone do not negate our opinions. I believe that all valuable opinions come from the minority side. Can anyone show an opinion coming from the majority, where anything invaluable has come?
