Sappiamo che cos'è la verità relativa?

I discuss a recent semantic proposal by Max Kölbel (2009) that indirectly explicates the notion of relative truth, or "truth for". I show that, due to the ambiguity of the prepositional phrase "For t" in contexts of the form "For t, t' is P", Kölbel's proposal is incompatible with essential aspects of moderate relativism, for one reading of "For t" makes relativism universal (as noted by Stanley 2005) while the other reading eliminates disagreement in standard cases of alleged faultless disagreement.
