 The measure of expected truthlikeness can be used for retrospective comparisons of past theories \(g\), if evidence \(e\) is taken to include our currently accepted theory \(T\), i.e., the truthlikeness of \(g\) is estimated by \(ver(g\mid e \amp T)\) (Niiniluoto, 1984, 171). In the same spirit, Barrett (2008) has proposed that—assuming that science makes progress toward the truth through the elimination of descriptive error—the “probable approximate truth” of Newtonian gravitation can be warranted by its “nesting relations” to the General Theory of Relativity.
