 The third question, applied to positism, is the question why certain beliefs are properly posited. Relativistic positists answer that this is so because of a certain societal fact: because they are taken to be so by an appropriate sub-sector of a certain society at a certain time. Non-relativistic positists answer that a certain belief is properly taken as a posit just in case every justificatory act that we engage in presupposes that the belief in question is true.
