 There is an important element of Ross’s intuitionism that Audi does not moderate, but instead makes more of than Ross. We previously noted that Ross’s conception of self-evidence is more restricted than the standard conception in that self-evident propositions are evident to those who have reached sufficient mental maturity and given them sufficient attention, rather than to anyone who understands them. The more restricted understanding allows an explanation of why people who understand a self-evident proposition might nevertheless not have a justification for believing it. On the plausible assumption that there is a close connection between what is evident for a person and what a person believes, Ross’s weaker conception also suggests an explanation of why some people who understand a self-evident proposition might believe it while others do not. Audi uses different terminology from Ross, formulating the relevant condition on self-evidence in terms of “adequate understanding”. But for Audi adequate understanding requires rather more than mere semantic comprehension, and, in the end, his view is probably quite close to Ross’s. Audi’s view of adequate understanding emerges when he explains how reasonable people could disagree about self-evident moral propositions as well as how one might continue to be justified in spite of disagreement (see 2015: 67–72). So Audi develops and does important work with the possibilities Ross’s more restricted conception of self-evidence opened up, but Ross did not much explore.
