Alright, let's break this down. First let's talk about this "truth predicate" business. It's basically a fancy way of saying something's true. Like, instead of "The Yankees are the best," you'd say "It's true that the Yankees are the best." Same thing, right?
But here's where alethic nihilism steps up to the plate. These folks, they're saying there ain't no such thing as a truth predicate. So, "It's true that the Yankees are the best" doesn't fly with them. It's not that they're saying the Yankees ain't the best, they just don't get on board with this whole "it's true" thing.
You're probably thinking, "Wait a minute, how does that even work?" We're always saying stuff's true. If I say "The Yankees are the best," and they really are the best (which they are, don't even start with me), it feels like a no-brainer to say my statement's true. But these alethic nihilist types? They're not having it. They'll tell you "The Yankees are the best," full stop. No need for this truth stuff.
Why would anyone think like this? Well, it helps them dodge some tricky philosophic traps, like this thing called the Liar Paradox ("This statement is false"). If there's no such thing as a truth predicate, bam, problem solved.
But let's be real, this ain't a popular view. A lot of philosophers think truth's a big deal, not something you can just toss out the window.
