A dumb statements thread? That is antiadhomical, as it's not the statements that are dumb but rather who makes the statement. Just kidding. People aren't dumb. Statements are. And they like sowing, apparently. Or at least they own some...thread. Or got caught with trace evidence of it on their clothing. Okay, so that's just a play on words--specifically, making light of its ambiguity.
Actually, despite the distinction between the person (who can be dumb) and a statement that is only dumb secondarily ... . And goodness gracious (!), what might I mean by secondarily? I mean that in the sense sentences can be thought of as true. If a proposition expressed by a sentence is true, then tied for first, both the proposition and statement are true. Up in second place, by the allowance of the powers of language, such sentences used to make a proposition making statement are true by proxy.
Speaking of statements and propositions, they are essentially the same, but wheresoever I can be found, there is at least one (me) ready to assert that there's always a distinction (even when synonyms in particular contexts vanquishes the differences). A statement, for example, is human dependent, but as a tool of philosophy, a proposition is meant to transcend time, so a proposition is MORE than merely what's expressed by a sentence.
So, given a time that predates language, the sentence "Earth has mass" did not exist, but truth is eternal (or some like such term) but a proposition is meant to transcend into the world of "but ifs." <-possibly the dumbest statement...but believe it or not, I could make it coherent at least.
Oh, and propositions that are false are not true, and vice versa. However, although sentences that are false are not true, the vice versa doesn't hold up. How so? Not all sentences express propositons. Those that don't are either true nor false, thus both not true and not false.
