 Once ‘property’ has been disambiguated, we can see how mental properties can be causally relevant after all. For now, if mental properties1 are tropes, they can be identified with physical properties1. Mental properties2 can still be distinguished from physical properties2, for properties considered as types are—in line with the standard view of tropes—identified with similarity classes of tropes. When Lisa removes her hand from the stove because she feels pain, therefore, she removes her hand in virtue of something that is partly characterized by a trope which is such that it belongs to a class of mentally similar tropes. This trope is identical with a physical trope—it is both mental and physical—because it also belongs to a (distinct) similarity class of physically similar tropes. Therefore, mental properties can be causally relevant in spite of the fact that the mental is multiply realizable by the physical, and in spite of the fact that we live in a physically closed and non-overdetermined universe.
