Objective reality is a state of affairs. States of affairs are not the
kinds of things which have truth values. Propositions about states of
affairs are the kinds of things which have truth values. To equal
Absolute Truth (a proposition) with Objective Reality (a state of
affairs) is equivilant to claiming that an apple is true or the annual
rainfall in the Amazon basin is false.
Objective reality is not the kind of thing which can be true or false.
It is what it is. Statements about objective reality can be said to have
a truth value, or in the case of science, a degree of accuracy.
Take care. -KMO
