According to a subjectivist view of some concept, C, there is an a priori implication of subjective responses in C's application or possession conditions. Subjectivists who intend their view to be descriptive of our practice with C will hold that it is possible for there to be true empirical claims which explain such responses in terms of certain things being C. Mark Johnston's "missing-explanation argument" employs a substitution principle with a view to establishing that these strands of subjectivism are inconsistent. I suggest that Johnston's substitution principle survives an attempt by Alex Miller to show that it is unreliable, but that it is prey to a counterexample which cannot be explained away by the proponent of the missing-explanation argument. I conclude that the missing-explanation argument poses no threat to subjectivism
