 By  (A5),  an assertion is permissible (appropriate, epistemically proper, warranted, correct—depending on one’s favorite terminology) only if it meets condition C, and impermissible if it does not meet C. Permission is related to the negative evaluation of assertions: assertions who violate N are prima facie faulty, and criticizable (qua violations of N). Permissibility only establishes what is necessary for permissible assertion, not what is  sufficient.[19]
