alt Hacker NewsPhilosophically, this is not true in general, but that's for trivial reasons: "how many integers greater than 7 are blue?" doesn't correspond to a formal question. It is absolutely true in many specific cases. Most problems posed by a mathematician will correspond to exactly one formal proposition, within the context of a given formal system. This problem is unusual, in that it was originally misspecified.
I suppose there's no formally defined procedure that accepts a natural language statement and outputs either its formalization or "misspecified". And "absolutely true" means "the vast majority of mathematicians agree that there's only one formal proposition that corresponds to this statement".
