Is hearing silence just a matter of inferring an absence of sound from one’s failure to hear? No, a wounded soldier who wonders whether he has gone deaf can hear silence while being neutral about whether he is hearing silence. He hopes he is hearing silence but neither believes nor disbelieves that he is hearing silence.
