 Burge has influentially asserted that brute errors about “present, ordinary, accessible propositional attitudes [such as belief and desire]” are impossible or at least subject to “severe limits”—where a “brute error” is an error that “indicates no rational failure and no malfunction in the mistaken individual” such as commonly occur in ordinary perception due to “misleading natural conditions or look-alike substitutes” (1988, 657–658; 1996, 103–104). However, Burge offers little argument for this claim, apart from the argument mentioned in Sections 2.3.1 and 4.1.1 above that for certain sorts of self-ascriptions error in general (and not just “brute error”) is impossible, due to the “self-verifying” nature of such self-ascriptions.
