 It has also been pointed out that even if we agree that seeing or grasping needs to be first-hand, and that others cannot do this for me, the same “first-handedness” apparently holds for belief. That is, no one else can believe for me, because believing is a first-personal act (Hazlett forthcoming: sec. 2.3). But just as this fact about belief does not lead us to think that propositional knowledge cannot be transmitted, so too it should not lead us to think that understanding cannot be transmitted (Boyd 2017).
