4262 If the only aim was consistent beliefs then new evidence and experiments would be irrelevant [Goldman]
6871 We can't only believe things if we are currently conscious of their justification - there are too many [Goldman]
6872 Internalism must cover Forgotten Evidence, which is no longer retrievable from memory [Goldman]

6874 Internal justification needs both mental stability and time to compute coherence [Goldman]
6875 Reliability involves truth, and truth is external [Goldman]
8831 Introspection is really retrospection; my pain is justified by a brief causal history [Goldman]
