3. Ten Leading Objections I shall now answer ten of what seem to me the dozen best challenges to a GGC account of function. Although some of these objections were posed against other types of analysis, since they affect a GGC account equally, I will reply. Most of them can apply to all GGC analyses, and often S&R analyses too. But some are specific objections to my own statistical species-relative account of biomedical normality. 3.1. Arbitrary, Evaluative, or Circular Goal-Choice
Both Melander and Schaffner charge that the GGC approach has no naturalis tic way to identity the goals of organisms, but instead requires the theorist to choose them arbitrarily or evaluatively. Melander (1997: 32-4), adapting Nagel’s example, imagines that a person’s kidneys and muscles reset the target they maintain for blood water content at Similarly, Neander (forthcoming: 53 n. 13) says: ‘Since there is no selection without varia tion, a trail that has no competition will not be selected for anything in the future (until an alter native allele arises)’. Millikan’s argument (1989fc 174) that Bigelow and Pargetter’s account is incoherent is, however, unconvincing. 17 Thanks to Michael Rea for this concise summan’.
