  Sometimes Nominalism is identified with those positions exemplifying strategy (a). But this seems to be based on the thought that what makes a position nominalist is the rejection of properties, numbers, propositions, etc. In this entry, however, I shall understand Nominalism in a broader way, namely as encompassing positions implementing strategies (a) or (b) above. For Nominalism has nothing against properties, numbers, propositions, possible worlds, etc., as such. What Nominalism finds uncongenial in entities like properties, numbers, possible worlds and propositions is that they are supposed to be universals or abstract objects. Thus the mere rejection of properties, numbers, possible worlds, propositions, etc., does not make one a nominalist – to be a nominalist one needs to reject them because they are supposed to be universals or abstract objects. Michael Jubien, for instance, rejects propositions, but he admits properties and relations construed Platonistically; his reasons for rejecting propositions have nothing to do with their alleged abstract character (Jubien 2001: 48–54). It would be odd to call Jubien a nominalist about propositions.
