  Derek Parfit’s Triviality Objection (Parfit 2011) is another contemporary extension of the Open Question Argument. If moral naturalism is true, says Parfit, then it will be possible to make moral claims and natural claims and have those two claims be about the same fact. Parfit worries that if the two claims are about the same fact, then those two claims must contain all the same information. And a statement of equivalence between any two claims that contain the same information must be trivial. But moral claims that describe the relationships between moral facts and natural facts are not trivial at all—they are highly substantive.
