 Of course the notions of “about” and “relevance” are notoriously difficult to pin down (Goodman 1961). And a speaker can know something is true without knowing everything about what makes it true. Often it will require empirical research to settle what makes a statement true. Moreover, what is determined a posteriori to be a truth-maker may exhibit a complexity quite different from that of the statement it makes true (Mulligan, Simons, &amp; Smith 1984: 299). Nevertheless, it is clear that unless (Entailment-T) is constrained in some way it will generate truth-makers that are unwanted because their presence conflicts with (Relevance).
