  There are no resemblance-tropes corresponding to these resemblance predicates. Another response denies that resemblance relations mark an addition to our ontology and, hence, there can be no regress of resemblance relations. Campbell, for example, argues that the successive resemblance relations in the regress are nothing over and above the non-relational tropes that ultimately ground these relations. Since resemblance is an internal relation, it supervenes on these ground-level non-resemblance tropes, but supervenient “additions” are not real additions to one’s ontology (Campbell 1990, 37).
