成唯識論述記 1.603

1.603

述曰：此中量云：所生之果色，應不名麁；與本極微等故；猶如本極微。又應返難：極微應是麁。量云：所執極微，應不名細；與麁量等故；如麁果色。

The Commentary states: The syllogism here is: The produced material effect should not be called coarse; because it is equal [in size] to the original atom; just like the original atom. Furthermore, a counter-challenge should be made: the atom should be coarse. The syllogism is: The posited atom should not be called subtle; because it is equal in size to the coarse [effect]; just like the coarse material effect.
