 The Independence Condition: The question as to whether the C-conditions obtain in a given instance must be logically independent of the class of truths for which we are attempting to give an extension-determining account: what makes an opinion best must not presuppose some logically prior determination of the extensions putatively determined by best opinions. (Justification: if we have to assume certain facts about the extension of P in the determination of the conditions under which opinions about P are best, then we cannot view best opinions as themselves constituting those facts, since whether a given opinion is best would then presuppose some logically prior determination of the very facts the judgement-dependent account wishes to view as constituted by best opinions).
