I think the intended implication goes the other way:
"But while we can't safely conclude that beautiful writing is true, it's usually safe to conclude the converse: something that seems clumsily written will usually have gotten the ideas wrong too."
In this sense it's similar to "Who speaks bad, thinks bad and lives bad. Words are important!" by Nanni Moretti in Palombella Rossa.
Hopefully that's not too much italianposting for the international audience :)
