Full Idea
Metaphysical realism about truth is a bundle of ideas: that it is a matter of Correspondence, that it exhibits Independence (of humans), Bivalence, and Uniqueness (there is only one ultimate truth).

A Reaction
It requires robust truth, but not correspondence (which is too strict, and too imprecise). Not sure about bivalence, which seems an unwarranted imposition. The other two seem fine, to me.
