  Scientific standards sanction propositions to a certain degree rather than outright. The latest hypothesis at the research coalface adopted tentatively by a few experts does not have the same standing as a long-entrenched theory. Thus the black-or-white notion of scientific standards sanctioning or not sanctioning p will not do. (This is an idea which Bayesian confirmation theory takes seriously.) It might also be argued that this is also true for mathematical standards, for example by considering non-deductive grounds for belief in mathematical propositions. It seems reasonable to see Goldbach's Conjecture, the claim that every even number greater than 4 is the sum of two primes, as supported to a high degree by the non-deductive evidence currently available for it. In the absence of a proof of Goldbach's Conjecture, however, this degree falls short of 1. A more precise statement of the naturalist's creed must therefore issue guidelines for apportioning credence in p in line with the degree and type of commitment to p scientific or mathematical standards recommend.
