 The generalization of the truth content comparison, by incorporating falsity content comparisons, also has some nice features. It preserves the comparisons of true theories mentioned above. The truth content \(A_T\) of a false theory \(A\) (itself a theory in the Tarskian sense) will clearly be closer to the truth than \(A\) (Diagram 1). And the whole truth \(T\) will be closer to the truth than any falsehood \(B\) because the truth content of \(B\) must be contained within \(T\), and the falsity content of \(T\) (the empty class) must be properly contained within the non-empty falsity content of \(B\).
