 Having made the point that the platonist explanation of (N) is uninformative, the nominalist's next move is to appeal to Ockham's razor to argue that we shouldn't believe in Gness (or at least that we shouldn't believe in Gness for any reason that has anything to do with the need to explain things like (N)). Ockham's razor is a principle that tells us that we should believe in objects of a given kind only if they play a genuine explanatory role. This principle suggests that if Gness does not play a genuine role in an explanation of the fact that gluons are G, then we shouldn't believe in Gness — or, again, we shouldn't believe in it for any reason having to do with the need to explain the fact that gluons are G.
