v. 1. Nominalism and realism.--v. 2. A theory of universals.

Available for the first time in 20 years, here are two important works from the 1920s by the best-known representative of the Vienna Circle.

Gonzalo Rodriguez-Pereyra offers a fresh philosophical account of properties. How is it that two different things (such as two red roses) can share the same property (redness)? According to resemblance nominalism, things have their properties in virtue of resembling other things. This unfashionable view is championed with clarity and rigor.

Bertrand Russell argued that any attempt to get rid of universals in favor of resemblances fails. He argued that no resemblance theory could avoid postulating a universal of resemblance without falling prey to a vicious infinite regress. He added that admitting such a universal of resemblance made it pointless to avoid other universals. In this paper I defend resemblance nominalism from both of Russell's points by arguing that (a) resemblance nominalism can avoid the postulation of a universal of resemblance without (...) falling into a vicious infinite regress, and (b) even if resemblance nominalism had to admit a universal of resemblance, this would not make it pointless to avoid postulating other universals.

Russell famously argued that Resemblance Nominalism leads to a vicious infinite regress in attempting to avoid admitting universals. Saying that a number of things are white only in that they resemble a particular white thing leaves a number of resemblances to that white thing, each of them constituting the holding of the same relation to the paradigm, qualifying that resemblance relation as a universal. Trying to dismiss that new universal by appeal to resemblances between those first resemblances only leads to (...) a new universal of resemblance, and so on. It is argued here that this does not arise for a properly formulated resemblance theory, which only requires one complex relation among the many particulars we deal with, a complex relation which is not multiply instantiated and thus not a universal.
