But you see that is the point, what one person may categorize as fiction, others may categorize as verifiable fact. That is the whole crux of the issue which you continue to miss completely. > "That's not an opinion." Of course it is an opinion. In fact, it is my opinion that it is an opinion :) Also, I think you may be defining opinion different than almost everyone else, myself included. The generally accepted definition is that opinions are beliefs or judgements about observable reality. And yes, such beliefs or judgements can be wrong. As such, they are intimately intertwined with the concept of 'knowing'. That is, how does one differentiate between 'knowing a thing to be true' and 'believing that a thing is true'. This is where epistemology enters the discussion. And you are categorically wrong in opining that it is not 'really relevant' ;)
