  The resemblance nominalist ontology is an ontology of resembling particulars like horses, atoms, houses, stars, men (and classes). But the resemblance nominalist does not reify resemblance. Thus that a and b resemble each other does not require that there are three entities there: a, b and a third, relational entity that is their resemblance. The only entities involved in that situation are a and b. In this respect, Resemblance Nominalism resembles Ostrich Nominalism. The difference is that whereas the latter admits many sorts of basic facts involving only particulars – ‘a is scarlet’, ‘b is an electron’ – the former admits only basic facts of the form ‘a resembles b to such and such a degree’.
