Acknowledging this difference, Cohen notes that we already know that there are “varying degrees to which competent speakers are blind to the context-sensitivity in the language” (2014, 74). The context-sensitivity of indexicals like ‘I’ and ‘now’ are easy to spot, that of ‘flat’ somewhat harder. And for ‘know’, “it may be very difficult even after some amount of reflection for competent speakers to accept context-sensitivity. It may take subtle philosophical considerations concerning the best way to resolve a paradox in order to ‘see’ the context-sensitivity of ‘knows’” (ibid.).
