@Jeff,
"This just in: FACTS ARE NOT OPINIONS. There is no false dichotomy at all.
"Simply adding, "I believe that..." in front of a fact doesn't change it into an opinion. That's a linguistic trap."
A fact is not an opinion, that's true -- in fact, they refer to different things (one's beliefs, versus what is true). However, some opinions are facts, and some are not. It is impossible to know something without both believing it and its being a fact. (Also there must be solid justification).
In short, every fact you believe in is, among other things, an opinion of yours (it happens to be a justified true opinion/belief). Putting a dichotomy between facts and opinions, therefore, is silly.
@Tru,
Thank you for the comments. I don't pretend to be an expert on CC, so I appreciate the perspective. I did find the quotation he included from the CC troubling. It seems to promulgate a trivially wrong but worrisomely growing misconception about epistemology in our society. I didn't mean it as any broader a complaint than that, though.
