It may be argued that Protagoras could have opted for a more sensible form of alethic relativism where a person’s beliefs are not automatically true relative to the framework she accepts. Rather a belief p is true according to X’s framework iff (roughly) X would believe that p if she were to reason cogently by her own standards on the basis of full relevant information. This form of alethic relativism allows for argument and persuasion among people who initially disagree, for despite their disagreement they may share or come to share a framework. Protagoras may, on this reinterpretation, be trying to persuade his interlocutor that if she were to reason cogently by her own standards from their shared framework, she would accept relativism. However, it is not clear how the relativist could share a framework with the absolutist on the nature of truth or what argumentative strategies he can use to convert the absolutist without presupposing a shared (relativist or absolutist) conceptions of truth. In particular, a consistent relativist will have only a relativized criteria of what counts as “true” information, which presumably will not be shared by the absolutist.
