唯識二十論述記 2.53

2.53

述曰：若許聚色量同極微，其諸聚色應不可見，量如微故。又立量言：汝麁聚色應不可見；量如微故，或即微處故；猶如極微。此中說宗，因如前說，然合與同處。此之二難，皆是設遮，非為本計。

The Commentary says: If it is accepted that the extent of aggregate form is identical to that of a paramāṇu, then all aggregate form should be invisible, because its extent is like that of a paramāṇu. Furthermore, an anumāna is formulated: 'Your coarse aggregate form should be invisible; because its extent is like that of a paramāṇu, or because it occupies the same location as a paramāṇu; just like a paramāṇu.' Here the pratijñā is stated, and the hetu is as stated before; however, conjunction and identical location—these two objections—are both hypothetical refutations, not their fundamental tenet.
