 The third and final strategy that platonists can pursue is to accept (1) and (2) and explain why (3) is nonetheless false. This strategy is different from the first two in that it doesn't involve the postulation of an information-transferring contact between human beings and abstract objects. The idea here is to grant that human beings do not have such contact with abstract objects and to explain how they can nonetheless acquire knowledge of such objects. This has been the most popular strategy among contemporary platonists. Its advocates include Quine (1951, section 6), Steiner (1975, chapter 4), Parsons (1980, 1994), Katz (1981, 1998), Resnik (1982, 1997), Wright (1983), Lewis (1986, section 2.4), Hale (1987), Shapiro (1989, 1997), Burgess (1990), Balaguer (1995, 1998a), Linsky and Zalta (1995), Burgess and Rosen (1997), and Linnebo (2006). There are several different versions of this view; we will look very briefly at the most prominent of them.
