 Opinions differ about the force of such examples. According to some, to require that understanding why p involves knowledge of mechanisms or deeper processes in this way would annihilate most of our everyday understanding (Grimm 2019a). Thus I can apparently understand why my eyes are watering—because I am chopping onions—without appreciating anything about the mechanism or connection that underlies the watering. Others argue that there is indeed understanding in these cases, although perhaps not a lot (Sliwa 2015).
