Interesting idea of yours - given that scientific 'facts' are simply a concensus of opinion as to the nature of a particular event. A fact cannot be obsolete, yet science is a field which involves ongoing revision of what we 'know'.
If an opinion (that is a hypothesis or conjecture) is shown to consistently predict facts in the future, it becomes a theory, meaning it accurately models facts. This is a form of truth.ChrisSmith24 said:Is there a line at which an opinion can become a fact?
Something can only truly shown to be superior by measurably quantifiable means. Portal 2 is a longer game than Portal. Portal 2 includes more game elements[footnote]that is, elements with which puzzles are built[/footnote] than Portal 1 does.. This does not equate to Portal 2 is better than Portal 1 unless you specifically define better as longer, or as with more game elements or both.My point is that if the only way we judge quality is based on opinions, something can never be proved superior.
Nope. Artistic merit, being a purely subjective issue, remains opinion. It may be a popular opinion (e.g. Portal 2 was well received by reviewers.) It may be the opinion of persons of import or reverence (e.g. John Blow, Shigeru Miyamoto, President Obama and Pope Benedict XIV all believe Portal 2 is a good game and would recommend it to their friends and family), but none of these things makes the quality of Portal 2 fact, or truth.Surely it is a fact that Portal 2 is a better game [than my barely working game demo]... Does anyone else agree that we should be able to state these things as facts, or should it never be able to be proven, as it is only opinions?
