Harold Doyle3 said:Look, truth can be subjective—it has an opposite, which makes it relative. But a fact? A fact doesn't have an opposite. It either exists or it doesn't. Simple as that.
If we follow that line of reasoning, everything would have an opposite, which would mean everything is relative, and we’d quickly run into a logical mess. The opposite of truth is a lie; the opposite of good is evil, so by that logic, both good and evil become relative. The opposite of life is death, making life relative too. Even the opposite of existence is nothingness, so existence and nothingness would be relative, and so on. Using that same flawed logic, the opposite of a fact is a non-fact, which would somehow make the fact itself relative. But obviously, having an opposite isn't the same thing as being relative. Relativity just means something is defined in relation to something else, and that "something else" doesn't necessarily have to be its direct opposite. You wouldn't say truth is relative because it depends on lies; rather, it's considered relative because it isn't absolute. It’s much like facts—either they exist or they don't. And really, the exact same rule applies to truth: it either exists or it doesn't.
Now, let's look at how Wikipedia defines it:
"Truth is the property of being in accord with fact or reality."
