  We rejected Ryle’s criterion for topic-neutrality because it appealed to an unclarified notion of aboutness. We rejected Goodman’s explication of aboutness because it assumed that the line between logic and non-logic had already been drawn. And we rejected Lewis’s account of aboutness because it did not distinguish logical truths from other kinds of necessary truths. How else might we cash out the idea that logic is “not about anything in particular”? Two approaches have been prominent in the literature.
